People in the Qin Dynasty, entertained during the Warring States period

He didn't want to gamble on whether Gongsun Long would yell and bite him.

The Black and White Sisters of the Yin-Yang School nervously watched Gongsun Long, who was about to harm Cao Ze. If they weren't outmatched, they would have already unleashed their Myriad Leaves Flying Flower Style.

Kong Chuan couldn't stand it anymore. This old man was too shameful. Just thinking about having to debate with this fellow tomorrow made him feel like he had no will to live.

"wisdom!"

After uttering the five-word mantra of Confucianism, Cao Ze clearly felt much clearer-headed.

Gongsun Long emerged from the abnormal state.

"I never imagined that one day I would be tormented by a single question to such an extent that I almost developed inner demons."

Kong Chuan admonished, "You old man, you're still so stubborn. Learn from me."

Gongsun Long glanced at Kong Chuan and said, "Should I learn something from you?"

"I don't know who it was back then who, under Lord Pingyuan's patronage, said to me, 'I have long admired your noble character and wish to be your disciple for a long time.'"

Kong Chuan's face darkened, and he snorted, "Don't take things out of context. No wonder you were kicked out by Lord Pingyuan."

Gongsun Long and Kong Chuan revealed each other's secrets.

If he could, Cao Ze would love to sit on a small stool, eat sunflower seeds, and watch the show.

Gongsun Long stopped criticizing Kong Chuan and looked at Cao Ze, saying, "Please enlighten me, young friend."

Kong Chuan breathed a sigh of relief. If Gongsun Long were to engage in a verbal battle with him on the spot, he might be in for a tough fight.

Cao Ze said, "Okay."

Then, Cao Ze wrote down the question about red and blue eyes on the huge wooden board.

The problem description is not complicated.

On a remote island lived 100 islanders, 5 of whom had red eyes and 95 had blue eyes. The islanders followed a strange belief:

First: They cannot look in a mirror or see the color of their own eyes.

Second: They cannot tell others what color the other person's eyes are.

Third: Once someone knows the color of his eyes, he must commit suicide that very night.

The islanders have always lived together happily.

Then one day, a stranger came. Unaware of the local customs, he inadvertently said something during a party with all the islanders: "You have people with red eyes here."

So, assuming that every islander on the island is smart enough, what would happen on this island?

This problem, posted online by a math genius years ago, attracted millions of views, but very few were able to figure it out and solve it.

When Cao Ze wrote down the question, everyone was dumbfounded.

Eighty percent of them couldn't even understand the questions.

Most of the remaining people, although they understood the questions and answers, had their brains completely shut down, which was worse than not understanding them at all.

Some quick-witted individuals, however, soon arrived at the answer.

For example, Li Si stated directly: "The answer is that everyone is dead."

Gongsun Long immediately roared, "I know everyone is dead, but why is everyone dead?! It doesn't make sense logically!"

Li Si was stunned by the shout.

Upon closer reflection, it's true that he knew everyone was dead, but he couldn't explain why everyone was dead.

Everyone on the island knows there are blue-eyed and red-eyed people, so this outsider's statement should be meaningless. Why then would the islanders commit suicide?

It seems that a starting point or source is missing to make the logic flow smoothly.

The great Confucian scholar Kong Chuan, who was about to speak, swallowed his breath in frustration. He shared the same view as Li Si, but he knew the reasoning behind it.

As for the Black and White Sisters and Mu Xuzi, they were all bewildered, wondering what had happened—that everyone was dead.

Cao Ze coughed lightly and said, "Everyone is dead. This answer is not difficult to come up with using the simplification and induction methods I have explained."

"But the biggest problem with this issue is what Mr. Gongsun mentioned: what caused everyone to die?"

The layman looks at the excitement and the insider looks at the doorway.

Anyone who achieves something will trace back to the source and will not be half-baked or pretend to know what they don't.

"First, before we can solve this problem, we need to understand two things: what is public knowledge and what is shared knowledge."

"As can be seen from the meaning of the words, shared knowledge refers to knowledge that everyone knows, but not necessarily that others also know the information."

"Public knowledge refers to the fact that everyone in a group not only knows the fact, but also that everyone else in the group knows the fact, and that everyone else in the group knows the fact... This is a process involving infinite knowledge."

After Cao Ze finished speaking, he began to write down a simplified logical reasoning process on the wooden board.

The most crucial point is that the new information brought by outsiders caused a change in the logic between the information.

Before outsiders came, there were people with red eyes on the island; this is not "public knowledge."

When outsiders arrive, they transform shared knowledge into public knowledge.

Gongsun Long was stunned for a long time before he suddenly came to his senses.

That makes sense.

He cursed, "Disgusting!"

Cao Ze just smiled; it really was disgusting.

If public knowledge is used well, it can be very powerful and terrifying.

Some people may not understand, but if you replace it with terms like game theory, pirates dividing gold, the prisoner's dilemma, or open conspiracy, then you'll understand.

The main theme is "I know you know, I know you know I know..."

Ultimately, both sides lose.

Those below the platform, whether ordinary people or disciples of various schools of thought, suddenly felt a crushing sense of being trampled upon.

The difference between people is even greater than the difference between a person and a dog pooping on the street!

Cao Ze spent another day leisurely and happily, not far from becoming famous throughout the seven kingdoms and a leading figure among the hundred schools of thought.

The scholars and common people listening to Journey to the West were very sensible; after he finished speaking, they all left.

Those with foresight have already begun organizing people to copy the novels by hand, preparing to open up the market for renting novels.

With so many characters, there's enough to produce several hundred letters for rent.

Cao Ze stepped down from the stone platform and saw the Black and White Sisters blocking his way. He smiled and asked, "Do you two ladies still have any questions?"

Shao Siming Bai smiled and said, "There are many doubts, but now we sisters would like to invite Mr. Cao Ze to our Yin Yang School's guest house for a chat."

Hei nodded: "That's right, my sister and I have something we'd like to discuss with you privately, sir."

He added, "It's very important."

Cao Ze really wanted to be in the same room with a beautiful young girl, especially since they were twins, hoping to spark some romance and have some beautiful misunderstandings.

But he was more worried that the Yin-Yang School might be setting a trap for him.

Who knows what's in the guesthouse of the Yin-Yang School?

There might be a few man-eating tigresses hiding there.

"If you two really have something important to do, why don't we go to Feixue Pavilion together? I was just thinking of going there to rest for a while."

The black and white sisters exchanged a glance and said, "Either is fine."

Chapter 99 My Sister with a Charming Purple Look

Yafei stood outside the house.

The snow woman slowly closed the door.

Ya Fei glanced at Cao Ze and Shao Siming of the Yin Yang School inside the room.

"Xue'er, I told you men can't be trusted. He even brought two women here for a secret rendezvous right in front of you."

Snow Maiden blinked her blue eyes and couldn't help but laugh, "Sister Yafei, what's wrong with you? You can't stop getting angry whenever you see him."

Ya Fei gave Xue Nu a sharp rebuke.

"It's all because of you, you brat! You tell him everything!"

The snow woman quietly stuck out her tongue, "That was just an accident..."

Ya Fei inadvertently recalled the day Cao Ze stumbled upon her secret, which she had kept in the wardrobe, in her boudoir.

Helplessly, he rubbed his forehead and said, "This damn accident."

Inside the room, Cao Ze made a cup of tea for the Black and White Sisters.

"Now that there's no one else here, you can speak now."

Bai pondered for a moment and said, "Mr. Cao Ze, please do not spread what my sister and I are about to say. Otherwise, it will not only harm my sister and me, but also you."

"Of course, I'm very tight-lipped."

He thought to himself, whether it's truly airtight or not, he didn't know, but he could say it's real.

Bai asked, "I wonder how much you know about our Yin-Yang School... um, about our Shao Siming?"

Cao Ze took a sip of hot tea and said, "It is said that Shao Siming is one of the five elders of the Yin Yang School. She holds a position of fierceness and evil. Her Ten Thousand Leaves Flying Flower Flow technique is so powerful that it makes people in the martial arts world tremble with fear. She is known as the 'Messenger of Death'."

Hei laughed and said, "It's all just hearsay. My sisters and I don't have that much bloodlust."

Cao Ze remained noncommittal, saying, "Women's words are deceitful."

With a worried expression, the white-faced man said, "Since you know that the position of Lesser Master of Fate is an inauspicious one, you must also know that the previous Lesser Masters of Fate did not exist for long."

Upon hearing this, Hei's eyes dimmed.

Bai formed hand seals and summoned leaves that were formed from his internal energy.

Cao Ze said with admiration, "Yin and Yang are born, and ten thousand leaves and flowers fly. It is said that the Shao Siming of the Yin-Yang School can control the birth and death of trees and plants, and release ten thousand flying flowers and leaves. Each leaf is sharp and sharp, and can cut through gold and jade, and make autumn orchids grow on flat ground. Among those of the same realm, there are almost no rivals."

Bai picked up a green leaf and placed it in front of Cao Ze, saying, "Sir, have you noticed anything different?"

Cao Ze released his senses and easily discovered that the green leaves not only contained Bai's internal energy, but also Bai's divine soul power.
