By linking my account to the check-in system, I became a leisurely traveler.

Chapter 267 Bear Bear Bear Bear Bear [Two-in-One]

"There's a bear!"

"Ah."

Li Younan casually turned off the volume of the radio broadcast that had been connected to the living area.

Now that the avalanche crisis is over, there is no longer a need to listen to the radio all the time.

"Junior high school math...is it difficult to learn?"

Li Younan focused his attention on the math supplementary material in front of Liu Li.

Liu Li lowered her head somewhat embarrassedly, but slowly removed her hand from her hand. "To be honest, it's quite difficult."

"That's normal, after all, you haven't studied for a long time."

Li Younan knew very well that the brain is adaptive. If you continuously perform a targeted and complex task for a period of time, it will form a conditioned reflex and inertia. The synapses in the relevant memory areas will also be activated, making them more and more flexible and stronger.

Conversely, if this complex task is not performed for a long period of time, the function of the corresponding area will deteriorate.

Liu Li dropped out of junior high school and doesn't even have a junior high school diploma. In a sense, her current education level is elementary school.

Many people think that junior high school knowledge is simple enough, but only when they actually relearn it do they realize that things are not so simple.

Liu Li found it somewhat difficult to learn.

But Li Younan also knew that feeling strained at this moment did not mean she was stupid.

Li Younan leaned over and took a few glances.

In terms of academics, Li Younan has enough authority to speak even without the system's advantages.

He was the top scorer in the county's college entrance examination that year, and even in the whole province, he would have ranked in the top 100.

Although some knowledge points may have been forgotten and some problem-solving skills may have become rusty over the years, the biggest difference between top students and ordinary test-takers from small towns has never been their ability to memorize knowledge points.

Especially mathematics.

Before resigning, Li Younan was an engineer, a job that required strong logic. His thinking and logical abilities not only did not deteriorate, but became even stronger.

In contrast, the amount of knowledge that actually needs to be memorized in mathematics is much smaller compared to physics and biology.

More importantly, it requires sensitivity to mathematical patterns and reasoning ability.

Therefore, Li Younan preferred studying mathematics during his student days.

The core of learning mathematics lies in... building your own knowledge framework.

It's not the kind of knowledge framework you memorize from a table of contents or mind maps, but a knowledge structure that you truly deduce step by step.

Li Younan simply flipped through the basic theorems at the beginning, and a region of his brain that hadn't been used for a long time was activated again.

The fundamental theorems are like the foundation, and the properties, characteristics, and key knowledge points on them are like building a house, which is quickly rebuilt in the mind.

There's really not much to learn in mathematics...

Li Younan smiled slightly, looking at the problem that Liu Li was struggling with. He not only saw where she went wrong at a glance, but also understood where her thought process went wrong.

"The formula for multiplication of polynomials is something that runs through all the knowledge points in junior high school mathematics."

Li Younan sat down directly next to Liu Li.

"This problem requires Vieta's formulas to solve, but your grasp of Vieta's formulas is not solid. You should say that you have only memorized the formulas, but you don't have a clear idea of ​​how they are derived. So, if the problem is slightly changed, you will find that Vieta's formulas cannot be applied."

"It's like building a house. Vieta's formulas are the roof of the house. You memorize the shape of the roof by rote."

"The questions you encounter are like telling you about the structure of a house, such as what the beams and columns are like, and asking you how to build the roof."

“You only remembered the shape of the roof, but if the beams are replaced with other shapes or more pillars are added, the existing roof can no longer be built.”

Li Younan tried to make Liu Li understand in the most intuitive and concrete way possible. Liu Li nodded thoughtfully, "Then what should I do?"

Li Younan patiently explained, "Start from the beginning, from the foundation, and gradually solidify it, so you can understand how the whole house is built."

"To truly master Vieta's formulas, it's actually quite simple. There's not much knowledge in junior high school. I'll go through it with you and see if you've mastered each basic theorem."

"First up is algebraic operations, which are the most basic and simplest concepts. Come on, let me see if you've truly mastered them..."

Li Younan patiently broke down the complex knowledge into simple theorems, first giving her test questions, and then patiently explaining it to her if he confirmed that Liu Li still had a superficial understanding.

"The second layer is the concept of equations and roots... This is actually a kind of knowledge similar to a small roof. We need to use this method to derive and understand it clearly, but it will be simpler than Vieta's formulas..."

"Great! You've completely mastered the first two levels. Next up is the third level, quadratic equations... This is a derivation tool, which can be seen as a method for building a house..."

Li Younan explained things in great detail. Liu Li was initially worried that she was too slow and had a poor foundation, and that she would be looked down upon. But the words Li Younan said most often were...

"Still don't quite understand? Hmm, it's not a big deal, it's not your problem, maybe I didn't explain it clearly enough. Come on, let's go over it again, I'll explain it more clearly."

They are so patient.

Liu Li recalled the attitude of her tutor when she was in junior high school. If she couldn't understand a knowledge point after two or three attempts, the tutor would definitely get angry.

Li Younan was so gentle...

It really makes me feel so at ease.

I'm also gaining more and more confidence in learning.

Time passed second by second, but the two of them did not feel the passage of time at all, until Liu Li's stomach growled and she suddenly realized that it was already dark outside the window.

My stomach is growling, how embarrassing...

Just then, the owl Tuantuan strode over with an arrogant gait. Liu Li patted its head and said, "Huh? Tuantuan, what are you calling? Coo coo coo..."

The owl blinked and tilted its head.

Li Younan laughed heartily, stood up, and said, "This little glutton must be hungry. Okay, I'll go cook."

Liu Li lowered her head deeply, feeling proud of her own cleverness.

However, after Li Younan left, Liu Li suddenly realized that an owl is an eagle... shouldn't it be "little gluttonous eagle"?

Uh……

Hate.

Liu Li puffed out her cheeks before turning her attention back to the teaching materials.

After Li Younan broke it down like this, she felt that math was really simple.

When learning mathematics, you cannot simply memorize theorems and formulas.

Every complex theorem and formula is like a tall roof; you have to understand the foundation that makes it up one by one. Once you understand them all, you will naturally understand the complex formula or theorem.

You can also use it to solve problems at will.

If you don't know where this formula comes from, it doesn't mean you don't understand the formula, but rather that you haven't mastered the prerequisite knowledge.

This indicates a weak foundation.

At the same time, some complex theorems and formulas may be the foundation of other theorems and formulas.

But when you break it down to the very bottom, it's all simple knowledge that even a fool could learn.

According to Li Younan, these simple theorems are rare in the field of mathematics.

Having grasped this core methodology for learning mathematics, Liu Li felt more confident about her future studies.

At this point, he also gained a deeper understanding of the differences between the thinking patterns of top students and those of ordinary students.

They seem to have an innate ability to quickly unravel complex systems and summarize patterns.

At this moment, Liu Li had spent several hours working on Vieta's theorem, but had not yet reached the final step. However, she was confident that she could derive it independently.

While Li Younan was cooking, she began to work out the deduction independently.

The solid foundation that Li Younan laid for her earlier was like a house that had already been built with a solid foundation and beams; all that was left was to put on the roof based on the existing structure.

This step is as simple as building a waterway, as natural as breathing.

The entire knowledge structure is now clear at a glance, and the confusion I felt when I was just memorizing formulas is gone.

Looking at the question again, it becomes as clear and straightforward as peeling away layers of an onion...

You can even guess what the question setter's thought process is like.

"So the question setter made a detour here; by simply modifying this part, the formula can be used..."

Liu Li happily finished the problem, then stretched and comfortably leaned back on the sofa, watching Li Younan busy at work.

Due to time constraints, Li Younan simply fried minced beef, added sauce, and served it with flatbread, wrapped with onions and lettuce.

Liu Li tilted her head back and said, "When I get into your university, will you send me there to study?"

Li Younan placed the food on the table and said, "If you get into my university, I will not only send you to university, but I will also stay with you there for at least a few months!"

……

Continuing on, we will venture deeper into the Yarlung Tsangpo Grand Canyon in Nyingchi, a section of the road that truly stretches into the heart of the plateau.

The journey from Bomi to Nyingchi is less than 230 kilometers. The road conditions are good, and the scenery along the way is picturesque. As a result, there are more and more tourist vehicles on the road.

Along the way, you'll find the Tongmai Bridge, a historical testament to how a once formidable barrier has been transformed into a thoroughfare; the charming town of Lulang, known as the "Oriental Switzerland"; and the Sejila Pass, the best viewpoint for the Shy Maiden Peak.

With this stop-and-go approach, sightseeing along the way, the short 230-kilometer journey ended before reaching the destination during the day. It was only after dark that the car had reached a point that was neither up nor down, which was rather awkward.

So Li Younan simply continued driving and drove all the way to Suosong Village.

Sosong Village is located in Milin, Nyingchi, nestled on the mountainside on the north bank of the Yarlung Tsangpo Grand Canyon at an altitude of about 3000 meters.

The main attraction here is Namcha Barwa, China's most beautiful snow-capped mountain, which is comparable to Mount Gongga and has an altitude of about 7800 meters.

At the same time, this is also the next check-in point for the system.

Around 10 p.m., Li Younan's car was about five or six kilometers away from Suosong Village when there were two or three cars parked on the road ahead.

Li Younan was a little puzzled. He wondered if the car was stopped in this place because there was roadwork ahead, or if there was some kind of trouble.

Thinking that the other party might be in some difficulty, Li Younan also stopped the car and said to Liu Li, "You stay in the car, I'll go down and check the situation."

Then he got out of the car and walked to the car in front to check the situation.

After getting off the bus and walking to the front, I saw three cars parked there in a row.

Judging from the license plates, the three cars came from the same place, indicating that they were traveling together.

Three men were squatting by the roadside smoking; they were probably the drivers.

Li Younan walked over and asked, "Have you run into any trouble?"

The three men looked at each other, then one of them stood up, laughed loudly, and said, "Brother, you're here to visit Suosong Village too, right?"

Li Younan nodded.

The man smiled and said, "We haven't encountered any trouble; we're just waiting for time to pass."

"Wait for time? What are we waiting for?"

“Brother, you don’t know this, do you? Suosong Village charges an entrance fee of 150 yuan per person and an additional 100 yuan per vehicle. They set up a checkpoint about one kilometer ahead, but the checkpoint is removed after 11 p.m. If we drive in under the cover of darkness, we can save several hundred yuan.”

For a moment, Li Younan was speechless. The other party then advised Li Younan to wait there for a while. It was already 10:30, and if he waited for another half hour or so, the checkpoint should have been removed.

For Li Younan, money wasn't the main issue; the thrill of "skipping the bill" was what mattered most.

Of course, strictly speaking, this can't really be considered skipping out on the bill. After all, besides those who deliberately wait until after 11 o'clock to enter the village, there are always some cars that are genuinely late, arriving after 11 or 12 o'clock. They drive in normally and accidentally don't get charged.

Li Younan thought for a moment and then got back into the car.

Liu Li immediately asked, "What's going on up ahead?" Li Younan said mysteriously, "If you stay here for another ten or twenty minutes, you can find money."

"what?"

About 20 minutes later, the car in front started up, and Li Younan slowly followed them.

Sure enough, after driving for less than a kilometer, there was a checkpoint. There was no one there, and the barrier had been raised.

After successfully passing the checkpoint, Li Younan accelerated and overtook the three cars in one go.

To his surprise, the three cars continued to follow him.

Li Younan didn't drive directly into the village. Instead, he found a suitable campsite some distance away and parked his car there, intending to spend the night there.

To his surprise, as soon as his car stopped, three other cars following behind him also stopped in the open space.

Although these three vehicles are not motorhomes, they have all been converted into beds so that people can rest and sleep on them.

All three cars belonged to couples traveling together, along with their two children.

Their car was parked not far from Li Younan's car, and the man who had spoken to Li Younan earlier came over to greet him.

The three families then set up a shared tent next to their car and cooked inside.

At this time, it should have been well past dinner time, but they had probably traveled for a long time and were bustling about.

During this time, they even came over to invite Li Younan and the others to have dinner together, but they politely declined.

Li Younan and Liu Li had both eaten dinner and were feeling a bit tired, so they decided to get some rest.

……

During this time, thanks to the meticulous care of Li Younan and Liu Li, the owl Tuantuan's health has been getting better and better. Not only has the splint on its wing been removed long ago, but it has also changed a lot from the disheveled feathers and frightened look when Li Younan first found it.

Now, Tuantuan has fluffy, thick, and glossy feathers. Its iris has also fully developed, and its claws are incredibly strong. It has grown into a large cat with a round head that is even bigger than that of an average cat.

Standing inside the RV, it's already an object that can't be ignored.

After all, Tuantuan's diet has been quite good during this period, with a constant supply of fresh meat and eggs. Compared to its kind in the wild who sometimes go hungry and sometimes have a full meal, it's a completely different life.

However, Tuan Tuan's wings were not fully healed yet, and she usually moved with a comical gait.

Anyone who frequently pets owls knows that owls rest during the day and are incredibly energetic at night, transforming from highly nearsighted individuals into super night vision devices.

To allow Tuantuan to release its pent-up energy, Li Younan would place it on the sunroof of the car so it could see the night view outside, calling it the "Guardian of the Night."

Liu Li said, "Won't it be too lonely up there all by itself?"

Li Younan said confidently, "No, he's actually quite happy. Look at him, after he went up to the skylight, even his eyes have become much sharper, like a real bird of prey."

Tuantuan straightened her chest.

It's worth mentioning that there's also a monitor on the roof, allowing you to see Tuan Tuan's situation in real time through the TV inside the car.

Li Younan built it a two-story wooden nest, with a roof and insulation layer on the upper level for resting, which was much more comfortable than the owl's natural nest.

The bottom layer of the cage is empty, and a garbage bag is placed inside for it to use as a toilet. During the day, the cage is left open outside the car. After Tuantuan finishes eating, it goes inside, uses the toilet, and cleans up its feces before being allowed to move around freely. This ensures that there will be no odor in the car.

Today, the same arrangement was made. Li Younan opened the skylight and placed Tuan Tuan's little nest on it.

The adorable owl transforms into a nighttime guardian in an instant when it climbs onto a skylight.

That's so cool.

Even now, the two still sleep in the same bed, innocent and pure. Liu Li is still shy, but very happy. Going to bed every night is something she looks forward to, because she can lean against her lover and smell his scent.

Li Younan felt that Liu Li's choice of words to express love was too grand.

She doesn't say "I like you," she starts with "I love you."

He once said, "I will only love one person in my life," and his definition of Li Younan is... a lover.

To be honest, in this era where so-called realism and so-called clarity are the mainstream, it's quite naive.

But in her own words, sacred love should be revered and believed in.

She genuinely believed that love was sacred.

Li Younan once said with a smile, "There might not be another silly girl like you in this world."

She said, "If one day I stop believing in love, it means I'm dead, or my heart is dead, and I will never love another person."

Despite never having been in a relationship, Long Mei is more alluring than any female player.

The little girl's silly words were like top-tier sweet talk, making anyone's heart flutter.

Not long after resting tonight, Li Younan suddenly heard Tuan Tuan making a cooing sound from the skylight.

Li Younan had a deep understanding of animals and keenly sensed that the call carried a very clear sense of alertness.

Li Younan rolled over and got out of bed.

Liu Li rubbed her eyes, still half asleep, and asked, "What's wrong?"

Li Younan checked the time; it was three in the morning.

He patted Longmei on the shoulder and said, "Tuantuan seems to have discovered something. It should be nothing serious. You rest well, I'll get up and take a look."

"Then...then you have to be careful."

Li Younan opened the skylight and let the ball out. Tuantuan tilted its head and looked at him, making two cooing noises before gazing into the darkness.

Li Younan frowned and looked in that direction as well...

Yeah, I can't see anything.

too dark.

Li Younan said to Tuantuan, "Shh..." and then went downstairs and closed the skylight.

He turned on the surveillance camera.

The vehicle is equipped with 18 surveillance cameras.

In fact, the lenses of these surveillance devices are very small. The exposed lenses are only the size of a coin, about the same size as the high-definition cameras on a family car, because the control center is integrated into the control center.

However, there are several infrared cameras among them.

It is a genuine infrared camera with a thermal imaging system, not some home-use night-lighting cameras.

When Li Younan turned on the infrared camera in the direction Tuan Tuan was looking and activated thermal imaging, Li Younan's eyebrows twitched the next moment.

Outside the open space was a wild field overgrown with weeds.

A huge animal was moving around inside.

Li Younan immediately recognized it...it was a bear!

It's late April now, and the bears have just finished hibernating. They're very hungry, so they're expanding their range and searching for food everywhere.

This bear is smaller than the grizzly bear that Li Younan sent away before, but it is still more than two meters tall and more than one meter wide at the shoulder!
This type of bear is perhaps the most cunning of all, and it will actively attack humans; there are cases of Tibetan bears eating people every year.

Those who have been eaten by Tibetan bears know that they can pretend to be harmless and cute, but if you think they are docile and approach them without warning, they will suddenly attack.

This thing is incredibly powerful; it can shatter a yak's skull with a single slap, and even a car window can't stop it.

It will even mimic a person waving from a distance to lure people closer.

Meanwhile, the bear drew closer and closer, eventually reaching the three vehicles.

The situation can be described as extremely dangerous.

Li Younan made a quick decision: he had to remind the people in the car immediately.

He quickly went to the driver's seat, started the engine, and then turned on the car's spotlights.

The spotlights modified on this Unimog RV are extremely dazzling; when turned on at full power, it looks like a small sun to oncoming traffic.

Intense sunlight pierced through the wilderness, but to Li Younan's surprise, the Tibetan bear was not frightened by the bright light. Instead, it slowly straightened up in the grass, tilted its head and looked at the scene with a harmless expression.

From a distance, it really looks like a person standing in a thick cotton-padded coat.

To be honest, it's a bit scary.

As expected, the light woke the people in the car.

Being woken up so abruptly was certainly unpleasant, but Li Younan had no choice—he didn't have the contact information for the people in the car.

At that moment, the window of the car closest to him rolled down, and the man who had greeted him earlier peeked out sleepily. He seemed a little resentful towards Li Younan, with whom he had just had a friendly exchange, but he still managed to suppress his emotions and asked, "Brother, what's wrong?"

Li Younan quickly poked his head out and shouted, "Bear! Bear!"

The other driver was still in a daze and hadn't reacted yet when the windows of the other two cars rolled down one after another.

One of the cars simply opened its door.

Li Younan immediately sensed something was wrong.

The driver got out of the car and came over to ask, "What's wrong?"

Li Younan pointed behind them: "Bear!"

At this moment, the Tibetan bear was not frightened at all. Instead, it put its forelimbs on the ground and slowly walked towards this side.

The group finally understood and turned around to look. They saw that the bear was only a few dozen meters away from them. They were so frightened that they lost all sleepiness and fled back to their car in a sorry state.

Li Younan wasn't idle either, pressing the horn several times in a row.

However, the horn failed to scare the bear away; instead, the beast quickened its pace and ran towards it.

However, the fact that several drivers have spotted the bear and successfully boarded their vehicles means that the situation is half-reliable.

But there's a problem: they've made beds and adjusted seats in the car, so even though they're on the bus, they can't just drive it away, which is quite inconvenient.

Then, in Li Younan's view, the Tibetan bear braved the bright headlights and piercing horns, fearlessly approaching the three cars.

Without a doubt, the people inside the car must be trembling with fear right now—their car is nothing like Li Younan's, which has thick armor, a high chassis, and can be started at any time in a critical moment.

Fortunately, they were all in the car. The bear might have the ability to break the window, but it might not be that smart.

Li Younan could only hope for the best.

However, the moment that thought crossed his mind, he was dumbfounded.

The bear kept sniffing the air and moved to the nearest SUV... then stood up.

Its claws scratched at the car door.

pat...

Suddenly... the car door was opened.

It opened, glistening and fresh...

Either the window was smashed, or the car door was opened from the outside without any warning.

At that moment, Li Younan felt as if the world had been paused for a second.

what?
Even someone who's seen a lot of big scenes was still a bit stunned by this sight.

No... let's not even talk about why the bear could open the car door...

Don't these idiots lock their car doors when they get in?!
