In the game "Super God," thankfully, it can simulate countless worlds.

[Simulation complete. Rewards are being generated. The host can choose one reward from the following options.]

1. Physics knowledge learned in simulation.

2. White Talent: Charlatan.

3. The nanofiber technology used in the Guzheng project.

4. Some reflections on life.

"I can only choose one of the four rewards." Lin Yuan looked at the four rewards generated by the system and made a decisive choice.

"I choose number 3, nanofiber technology!"

Logically speaking, talent should be the best reward, but unfortunately, Lin Yuan really doesn't like this white talent, "The Charlatan," and choosing this talent might even change his personality.

Lin Yuan would definitely decline such a reward.

He wouldn't choose a reward that could change his personality, no matter how powerful it was.

While physics knowledge is somewhat useful, it pales in comparison to nanowire technology.

Even with Lin Yuan's limited knowledge of physics, he couldn't create nanowires even in a hundred years.

Life lessons are even less useful; anyone can spout grand principles!

After selecting the reward, the production process of nanowires and related knowledge quickly appeared in Lin Yuan's mind.

"Um……"

Rubbing his forehead, Lin Yuan gradually digested the not-too-overwhelming amount of knowledge.

"These nanowires are only one-thousandth the diameter of a human hair, yet their strength is comparable to that of a diamond." Lin Yuan read the description of the nanowires.

In the Three-Body universe, the official force used a large net composed of nanowires to cut the ETO organization's headquarters, Judgment Day, into pieces.

This is definitely a versatile material, involving a lot of nanotechnology, which broadened his horizons.

Lin Yuan stroked his chin: "Most importantly, the cost isn't too high, and it can be mass-produced."

"This is going to be a windfall!"

If we had this technology, we could start a high-tech company. This advanced material can be used in many fields, and we could make a lot of money just by selling the patent!

However, Lin Yuan suddenly remembered the large chrysanthemum above Juxia City.

"What the hell are you talking about?" Lin Yuan sighed helplessly.

It's the end of the world, money doesn't matter, what matters is strength!

"System, simulate again!"

[Insufficient simulation attempts. Special simulations can be obtained by recharging. Would you like to recharge?]

"Top up! Top up now!"

Is that even a question? You'd have to go bankrupt to top up your account.

[The first recharge in this special simulation was for 1,000 yuan. Insufficient funds were detected in the host's bank card, and the recharge failed.]

Upon seeing this sentence, Lin Yuan couldn't help but twitch his lips, feeling the deep malice this world harbors towards the poor.

As an orphan, he received considerable government subsidies, mostly for things like tuition waivers, textbook waivers, and meal card top-ups.

There was definitely a monetary subsidy, but these days computers and mobile phones are standard equipment for college students. Lin Yuan gritted his teeth and chose to buy some high-performance components to assemble a laptop himself, and also bought a smartphone.

This cost him most of his savings, leaving him with only one month's living expenses.

As for scholarships, the school hasn't issued any yet this semester. The key point is that knowing the world is about to end, he's too lazy to even apply for any scholarships.

The money is about to become worthless, so why bother with all that trouble?

"Does this mean that with the world about to end, I'll have to go out and work to earn money?"

Impossible! Absolutely impossible!

"It's okay, I still have the sign-in simulation in this world." Lin Yuan comforted himself, he still had a choice.

"As an important character in the storyline of Galaxy Force, Ge Xiaolun will definitely receive a sign-in reward."

He's tried the special simulation, but he hasn't tried the simulation of this world yet.

It's unclear whether he can survive the three-year simulation limit in the simulation.

Lin Yuan got out of bed, dressed, and decided to go out for a walk.

Staying in the dorm means you're unlikely to encounter many special characters who trigger the sign-in event.

"I just don't know if ordinary people, besides the characters in the story, can trigger the sign-in event."

Looking at the time, Lin Yuan realized that although he had gone through a simulation, not much time had passed, and there were still ten minutes before the first class started.

"How about we go to class?" Lin Yuan thought for a moment, since he had nothing else to do anyway.

Moreover, Ge Xiaolun is also in class. He needs to sign in as a character. As the protagonist, surely Ge Xiaolun can't even sign in?

Lin Yuan rushed towards the teaching building and finally arrived at the classroom at the last minute.

"I thought you weren't coming!" Good student Ge Xiaolun was sitting in the first row. When he saw Lin Yuan walk in, he waved to his troublesome roommate to sit next to him.

Didn't you see the murderous look in the female teacher's eyes behind the lectern?

The teacher giving this open class was a middle-aged woman who was holding up the attendance list and staring intently at Lin Yuan.

Lin Yuan felt a chill run down his spine. He casually glanced at the students in the classroom and was about to go to his seat when he suddenly stopped.

He was surprised to see two people, one in white and one in green, signing in at the classroom!

The green light above Ge Xiaolun's head did not surprise Lin Yuan.

The story hasn't even started yet, and Ge Xiaolun is just an ordinary person. It's already quite good that he can refresh the green sign-in.

If a golden sign-in reward is actually refreshed, the difficulty of the task will probably be explosive. If it's something like defeating Karl or solving the Void Fear, Lin Yuan can only sigh in vain.

For him, the role of Ge Xiaolun is essentially useless.

But what's with this white sign-in sheet? Could there be some hidden big shot among his classmates?

"Student, do you want to stand and listen to the lesson?" The female teacher's tone was already impatient when she saw Lin Yuan standing dumbfounded at the front of the classroom.

It's already class time, and not only did they arrive at the classroom just in time, they even dared to delay her class.

Do you really think she's easy to talk to?

"I'm sorry, teacher." Lin Yuan quickly admitted his mistake, then decisively ignored Ge Xiaolun and walked quickly to the back row, heading towards the white sign-in area that had been refreshed.

Arriving at a female classmate's seat, Lin Yuan glanced at the white name tag above her head and plopped down next to her.

When Qin Xuan saw Lin Yuan sit down next to her, she lowered her head with a slight blush.

[White Check-in Task: Become friends with Qin Xuan.]

"Damn it, system, don't mess things up!"

Lin Yuan's expression changed slightly; he hadn't expected the sign-in task to be making friends.

"What kind of friend is this? A fair-weather friend or a close friend?"

Does a nodding acquaintance count?

Lin Yuan pondered inwardly, noting that the system offered no explanation.

It can't be her girlfriend, can it?

"Um," Qin Xuan mustered her courage and looked up at Lin Yuan, "we've been classmates for so long, and I still don't know your QQ number or anything."

"Want to add each other as friends?"
