I am cultivating immortality in the chaotic world.

Chapter 304 "You also know probability?"

The corridor continued to rush forward at an extremely fast speed in the dazzling light, and its target was exactly the sixth level.

At this time, many people in the secret realm have already qualified to leave.

After all, to be eligible to leave the secret realm, one only needs to pass four levels.

However, up to now, no one has left the secret realm. The rest of them still want to take a look to see what the content of the next level is. If the content of the next level is too difficult, they can leave the secret realm at that time.

It is worth mentioning that.

Since the fifth level, there has been no doubling mechanism. Regardless of whether the fifth level is passed or not, the rewards for subsequent levels will not be doubled.

at this time--

"Hi."

The host of the secret realm who was away from the crowd suddenly thought of something, slapped his head, looked at the crowd and said embarrassedly: "I suddenly thought of something, I forgot to mention it just now. Logically speaking, some of you already have the qualifications to leave this secret realm. As long as you are willing, you can leave this secret realm at any time."

"but."

"You just chose to give up leaving this secret realm, and this sixth level is a bit special. Once you choose to give up leaving the secret realm, you must pass the sixth level to have the opportunity to leave the secret realm again."

"That is to say, those of you who have the qualifications to leave the secret realm just now need to pass the sixth level before you can successfully leave the secret realm."

The voice just fell.

The faces of most of the challengers instantly turned gloomy. Isn't this a damn threat? Originally, they were just curious to see what the content of the sixth level was. What if the content of the sixth level was very simple? Wouldn't that be a lucky break?
It turns out that there is such a rule. The most important thing is, why is such a fatal secret realm rule not explained clearly in advance?

You are too unqualified to be a secret realm challenger.

As for the rest of the people, their expressions showed no joy or sadness, and they completely ignored this rule. These people were all veteran gamblers, and they had to pass the sixth level to be eligible to leave the secret realm, so naturally they didn't mind this rule.

Anyway, they are not qualified to leave the secret realm yet.

Although everyone had already started cursing in their hearts, no one spoke. The strength of the host of the secret realm was unquestionable, and if they spoke at this time, they would most likely be killed on the spot.

They felt the real example when they first entered the secret realm.

at this time--

The speed of the corridor slowly slowed down, the dazzling light around gradually dissipated, visibility gradually increased, and right in front of the void was a palace.
A huge palace.

The tallest building was even thousands of feet high, and each step was several feet high. The entrance gate was nearly a thousand feet high. If a mortal was put into a palace of this size, he would not even be able to cross the steps.

This is more like a palace built for giants.

For example, the barbarians.

"arrive."

The host of the secret realm looked at the palace in the distance, and said seriously, "This is the final destination of this secret realm, the 'Immortal Palace'. It is said that I don't know. There is no relevant information about this palace in the secret realm, but I think it must have a magnificent history. You can imagine it yourself."

"It's called 'Immortal Palace'. Maybe an immortal died here."

"The sixth, seventh, eighth, and ninth levels of this secret realm are all within this palace."

The speed of the corridor had gradually slowed down, and soon it stopped at the first step. As a wooden door slowly emerged on the wall of the corridor, Chen Lu, leaning on the Tianji Umbrella, was the first to push open the wooden door and landed on this step.

"."

Chen Yu didn't say anything, just looked around.

The steps in front are several feet high. From a distance, you can only see the grandeur and height of the palace, but only by observing it up close can you see the details contained in it, including these steps, buildings, and even the entire palace.

They are all made of a huge stone.

There is no splicing method at all; all buildings, steps, etc. are not built but carved out.

It is like a skillful craftsman carving a "Hundred Herbs Picture of All Living Beings" on a piece of jade.

This method requires supernatural skills, extremely high cultivation, top aesthetic and artistic attainments, and extremely deep financial resources. It is not a simple method to get such a large and integrated stone.

not to mention.
This is no ordinary stone.

He had an entry that could see through the information of treasures, and when he focused his eyes on the stone under his feet, a panel slowly emerged in front of him.
-
「Treasure name」: The Great Stone of Creation.

[Source]: A monolithic mass of stone on the original continent.

「Effect of use」：
1: It is extremely strong. Carving a formation on its surface will greatly enhance the power of the formation. The stone will also purify the spiritual energy in the air at all times, making the spiritual energy purer and richer.

2: Excellent forging material.

3: Can be used to conceal the secret.

4:.-
"."

Chen Lu narrowed his eyes slightly. The origin of the huge rock under his feet was indeed extraordinary. It was a completely integrated huge rock on the "Beginning Continent" and possessed all kinds of magical effects. The three words "Beginning Continent" sounded quite intimidating, and he did not dare to think about it too much.

Instead, he tilted his head and looked into the distance.

The entire palace is located peacefully in the middle of an endless void. One day feels like ten years, peaceful and quiet. Although no one knows how long this palace has been sleeping here, one can clearly feel the heaviness of time emanating from this palace.

There were carved patterns on the ground. He couldn't understand what they meant, so he just secretly memorized them to see if he would have a chance to study what they meant in the future.

The spiritual energy in the palace is relatively pure, far exceeding the spiritual energy density of the Qitian Continent. He has never been to the fairyland, but he has roughly sensed the density of the spiritual energy in the fifth-grade fairyland. When Badan went to the fairyland for the first time, he personally broke the barrier between the fifth-grade fairyland and the fourth-grade continent. A lot of spiritual energy leaked out of the fifth-grade fairyland. The density of spiritual energy sensed at that time was not as high as that here.

If he could practice here, his practice speed would increase rapidly.

at this time--

"what!!!"

A piercing scream was heard suddenly, and a young man was seen not far away standing on the edge of the stairs, holding his broken arm and screaming in pain. In the void beside him, one could clearly see that a broken limb was slowly being crushed into powder.

obviously.

The man cast a spell with his own body, wanting to try out what this nothingness was made of. Now it seemed that he might have some idea. He only knew that there was no spiritual energy in the nothingness, but it was also the first time he knew that nothingness could have such a powerful destructive power.

This young man had reached the peak of the Refining Void realm after all, but he was unable to resist at all.

Moreover, several breaths have passed, and not only has the broken limb not regenerated, but the bleeding has not even stopped. This is a bit strange. Normally speaking, a person with such cultivation level would be able to stop bleeding even if his limbs were broken. This means that wounds cut by nothingness not only cannot regenerate, but cannot even stop bleeding.

At this time, everyone was looking at the young man and witnessing the fountain of blood. There were a few of this man's companions around him, who tried all sorts of tricks but were powerless.

Until
After dozens of breaths, the young man, in front of everyone's gaze, bled wildly until all the blood in his body had been sprayed out. Finally, he fell to the ground with a pale face and gradually dilated pupils, completely announcing the end of his life.

"Um"

After this scene, the host of the secret realm sighed and said, "Every time someone wants to give it a try, I don't know why they are so curious. I'll remind you that before I speak, it's best to follow me and don't go to some places rashly."

“It’s easy to lose your life.”

"Please look up and see how magnificent this palace is, and think about how dangerous this kind of place is."

"Now everyone gather together, I will take you to the sixth level."

As the words fell, the crowd gradually gathered together. After all, this place did seem to be full of dangers, and it was safer to follow the host of the secret realm, even though many rules were not announced in time.

"senior."

The host of the secret realm trotted over to Chen Yu's side, whispered a few words, and then returned to the crowd and coughed lightly: "Next, let me introduce the rules of this sixth level to everyone."

"See those steps in front of you?"

"There are eighteen floors in total. There are thirty-six bricks on each floor, so there are six hundred and forty-eight bricks in total. It's a very auspicious number, right?"

"Climb up these eighteen steps and you will see a huge gate a thousand feet high. That is the entrance to this palace, and also the entrance to the seventh level."

"And these bricks are the sixth level of all your challenges."

"These 648 stone bricks will trigger a corresponding effect each time you step on one of them. It could be disastrous or rewarding. It all depends on your luck. This level has nothing to do with your strength. It's mainly a test of your luck."

"of course."

"I know you can fly, but I need to remind you."

"You can fly, but you must step on a stone brick on each step. If you skip the steps, you will be punished by heaven. If two people land on a stone brick at the same time, the double rule will be triggered, and both the reward and the disaster will be doubled."

"In other words, you have to step on eighteen stone bricks before you can reach the top."

"Of course, there is no need to be too afraid. Many of the disasters here are not fatal."

And at this time——

The people in the square discovered that hundreds of large characters had appeared on the ground beneath their feet at some point, and these large characters clearly introduced the rules of the sixth level. They were almost exactly the same as what the host of the secret realm had said, without any mistakes.

The only additional reward is for passing this level.

"A Meridian Stone from the 'First Continent'."

The only effect of this meridian stone is that it can peel out the non-tradable existences such as the fortune of ghosts and the fortune of geniuses in one's own dantian or the dantian of others, and form them into a jade slip-like existence.

The effects are permanent.

Of course, when depriving others of the fortune in their Dantian, it must be done with the cooperation of others, or when they are in a state of unconsciousness and unable to resist. It is impossible to forcibly strip it away from a distance. If there is such a means, this kind of reward cannot appear in the sixth level, or even the ninth level. It is too difficult.

These eighteen steps are the only entrance to the palace in front of us.

The square is in contact with nothingness on three sides.

If you want to go around and reach the top, you can only go through the void, but the power of nothingness has just been demonstrated to everyone by someone himself.

This level is almost entirely based on luck.

It has nothing to do with strength.

However, the crowd did not rush to break the level immediately, but subconsciously looked at Chen Lu who was standing on the side of the crowd. The host of the secret realm had just whispered something to Chen Lu. Although no one knew what they said, it was probably about how to break this level, some skills that they didn't know about.

"."

Chen Lu frowned slightly and looked at the eighteen steps in front of him. The host of the secret realm did not reveal any skills to him just now. Under the rules of heaven, the host of the secret realm did not dare to reveal to him any information that could help him pass the level, unless it was within the host's authority.

I just whispered to him.

"Senior, this level is difficult, be careful."

Yes.

I didn't tell him any tricks, I just told him that this level was difficult.

He was thinking about a question now, relying entirely on luck? Then could he consume a ray of Tianjiao's luck to ensure that he could basically pass the test 100%? But he was a little unsure whether the luck gained after consuming Tianjiao's luck could be applied in this regard.

All the items handed out in the previous levels are sealed in jade slips and are grey in color. They cannot be used normally and can only be used after leaving the secret realm.

Among the people present, not many have the fortune of earthly pride or heavenly pride in their dantian.

However, he felt that this level should have some skills, and should not rely entirely on luck. Although he thought he had good luck, he did not want to gamble on his luck unless it was absolutely necessary. The most important thing is
How did that person named "Jiang Buping" pass this level? He must have his own means. A person of this strength cannot pass this level by relying on his luck.

This is equivalent to if you are a person who practices Qi training, when fighting for a spiritual treasure, you are willing to gamble your luck with your life.

But if you are a celestial being, you probably won’t gamble on your luck.

The reason is very simple. The input and output are completely disproportionate. The stronger a person is, the less willing he is to gamble on his luck. Once he loses the bet, everything is lost.

Perhaps, the conditions for passing the level have something to do with the patterns on the ground.

at this time--

The host of the secret realm spoke up again to remind them, "Oh, I forgot to tell you just now. The rule for the sixth level is that you must reach the top within one stick of incense. If you fail to reach the top within one stick of incense, you will be punished."

"God's punishment?" a challenger asked.

"No."

The host shook his head seriously.

"After one stick of incense, the barrier here will disappear, and nothingness will cover the ground square and these eighteen steps. That..."

He didn't know what he was thinking about, and shrugged his shoulders and said, "That scene was a bit cruel. I personally suggest that you need to speed up the process."

The words fell.

The faces of everyone present turned ugly again. Why did this secret realm always have some messed up rules? The most important thing was that they were not informed in advance. If they had known earlier, if they gave up before the sixth level and had to pass the sixth level, they would never stay there for too long.

If they can pass this level, they will definitely not stay any longer at the next level and will go straight home without stopping at all!

but now.
The most important question is how to pass this level first.

"I come."

At this time, an old man with a hint of confidence on his face strode up from the crowd and walked to the front of the steps. Then he took a deep breath, and with the surge of spiritual energy, he suddenly jumped up and landed on a stone brick on the first step.

next moment--

A light mist appeared on the surface of the stone bricks, and then a spinning "dice" slowly emerged above the old man's head. The spinning speed gradually slowed down, and finally the surface of the dice stopped at "four o'clock".

Before anyone could react, in front of everyone's eyes, the faint mist on the surface of the stone bricks slowly condensed into hundreds of high-quality spirit stones.

"Hahahaha!"

Amid the old man's wild laughter, everyone suddenly realized that they had passed the first step and the hundred high-quality spirit stones had been stored in the old man's storage ring.

The old man's eyes were filled with more confidence. He stood on the first step and looked down at everyone. "I just consumed a ray of my luck. In a short period of time, my luck will be greatly improved."

"Then I will leave first. I wish you all good luck."

Say it.

The old man did not stop at all, and leaped onto the second step more confidently. As mist poured out from under his feet, a dice appeared above his head again, and this time the dice stopped at "three".

The mist suddenly turned into a thick flame, enveloping the old man completely. However, the flame only lasted for a moment and soon dissipated.

When the flames faded.

You can see that the old man was slightly injured, but it was only his beard that was gone and some superficial injuries. His overall condition was still good.

"Humph."

The old man frowned and snorted coldly, and soon found an explanation: "I understand now. Four, five, and six points are opportunities, and one, two, and three points are disasters. If I hadn't been protected by the luck of a genius, I would probably have gotten one point."

After that, the old man had almost smooth sailing.

"Five o'clock", "Four o'clock", "Five o'clock".
Almost in the blink of an eye, they reached the seventh floor.

The challengers standing in the square who had not taken a step yet looked in the direction of the old man with envy in their eyes. They knew that consuming the luck of the genius could temporarily increase luck, but they had never used it in this way. After all, it was a bit of a waste.

It seems that possessing a treasure like the Luck of a Prodigy that can increase luck for a short period of time can effectively help one pass this level.

The previous level actually rewarded them with a lot of luck.

But they are all sealed and cannot be used now. You can only truly obtain these rewards after leaving the secret realm.

but
Many people's eyes flickered, and they were secretly delighted in their hearts. They had already memorized the old man's route. They just needed to let the old man go first, and then they would continue to follow the old man's path.

They are naturally happy that someone is willing to lead the way.

At this moment everyone subconsciously remained silent, fearing that the old man would react, and they were unwilling to be the first to rush forward.

at this time--

All the challengers were stunned when they saw the old man who had reached the eighth step. The dice above the old man's head stopped at the "one point" position. One point, if it was at the "one point" position,
There was no time for people to think too much.

next moment!
"boom!!!"

Suddenly, there was a deafening thunder in the sky, and then a bolt of lightning several feet thick came straight down and hit the old man who had already jumped onto the eighth step.

When the thunder dissipated.

The old man was no longer on the eighth step. Only some charcoal drifting in the wind vaguely proved that everyone was not hallucinating.

"Dead?"

A man looked at the scene in front of him with horror, his tone full of confusion and fear. Why? He had clearly consumed "a ray of luck of genius" and greatly improved his luck for a period of time, so why did he get "a point" randomly?
This is unreasonable!
Isn't the luck of the genius enough?
For a moment, the feeling of fear spread again in the hearts of the challengers, but after such a delay, there was not much time left before an incense stick of time. A middle-aged man, while no one else could react, was the first to jump onto the first step and landed accurately on the step where the old man had just landed.

The mist dispersed under their feet again, and everyone reacted immediately and looked at the man.

When the man lowered his head to pick up the white top-grade spirit stone, he found that the mist under his feet did not dissipate for some reason, and did not condense into substance and turn into a spirit stone like the old man.

Just when the man felt a little confused and subconsciously looked at everyone, he saw fear in everyone's eyes.

stunned for a moment.

Then an incredible possibility suddenly flashed through his mind, and he looked up at the dice above his head with a trembling body. Sure enough, the number on the dice above his head had stopped at "one".

next moment!
"Do not!!!"

Amid the man's heart-wrenching and unwilling roar, a bolt of lightning struck again.

obviously.

Even if it is the same floor tile, it does not mean that the dice points triggered by stepping on it are the same. The dice points are completely random. This also means that it is meaningless to step on that stone tile, and the dice have to be thrown again anyway.

"I see."

Fei Long looked at the eighteen steps in a trance. "That is to say, every time you throw the dice, there is a one in two chance that something bad will happen, one, two, or three points respectively."

"Although I haven't seen two points, I should be able to infer from one and three points that three points is a small disaster that may cause minor injuries, and two points is a serious injury that is not fatal."

"One point means certain death."

"That is to say, every time you step on a step, there is a one in six chance of sudden death."

"If we use probability theory to explain this level, then the probability of "Event A" occurring is one in six, and this "Event A" means sudden death. In 18 independent repeated experiments, if we want to make this Event A happen once, we can finally pass the level successfully."

"therefore--"

“In 18 experiments, the probability that event A does not occur is (5/6)^18.”

"The final calculation shows that the probability of survival is 0.000003326"

"That means if you rely purely on luck, the chance of surviving the final clearance is about 3326/1000000."

"One million people can survive more than 3,000."

"Ah."

Fei Long nodded silently and touched his nose: "With such a low survival rate based purely on luck, it can basically be said that this level cannot be based on luck. There must be other ways to pass it."

"."

Chen Yu looked away from the pattern on the floor tiles with a slightly strange expression, and tilted his head to look at Fei Long: "You also understand probability? You can do mental arithmetic quite fast."

"Understand a little bit."

Fei Long said a little embarrassedly: "It should be calculated like this, there may be some deviations, but not too big. This is all I understand. But I can be sure of one thing, that is, this number is indeed a bit scary."

"If we calculate the probability of a single cell."

"For example, if the first seventeen layers of "Event A" did not happen, then the probability of "Event A" happening on the eighteenth layer is still one in six, and there is no problem with this."

"After all, each event exists independently."

"But if you take the overall picture into account, the probability is very low."

"Ah."

Chen Yu nodded slightly, then looked at the many challengers who had already climbed the stairs and started to gamble their luck and said softly, "Your number sounds much scarier than the rules of this level. If they knew this number, they probably wouldn't walk up the stairs so easily."

The rule panel of this level will make you feel that although the probability is low, it doesn’t seem that low.

Just be lucky 18 times.

And there is still a five-sixth chance.

But in fact, the probability of survival in the end is frighteningly low, basically impossible. At this point, it is probably understandable why the old man consumed his "luck of genius" and still died suddenly in the end.

After all, "Fortune of the Prodigy" only enhances your luck, it doesn't make you completely invincible.

With the probability that only more than 3000 people out of a million can survive, even if the luck is further enhanced, it is difficult to increase it to %.

"but."

Fei Long shrugged indifferently and said with a smile: "But it doesn't matter. We don't need to gamble on this probability. Brother Lu, you have been observing the patterns on the ground just now. You must have found a way to pass the level, right?"

"No."

"No?"

Fei Long was slightly stunned, and subconsciously murmured: "No, then why did you move your eyes away from the patterns on the ground of the square? I thought you had already..."

"Oh."

Chen Yu lowered his head again to observe the patterns on the ground, and said casually: "You are talking to me, right? I looked up at you, it's social etiquette."

"Most of the time, I'm still a very polite person."

"But you are right about one thing."

"I do have an idea, but I'm not sure if it's the final solution. I need to experiment."

(End of this chapter)
