I have to admit that Lu Zhi is worthy of the name of the great Confucian of the current dynasty, and his knowledge is so profound that even Luan Yi, a person from the future, can hardly look at his back. Astronomy and geography are omniscient, the subset of history is like a stream, and the art of war is free. Luan Yi learned a lot from him.

Lu Zhi obviously likes to chat with Luan Yi as well, the reason is very simple, although the young man in front of him is not like him quoting scriptures and classics, but the words he says are very simple, which implies a lot of thought-provoking truths, and from time to time he will say surprising words, and some opinions that he has never thought of. At first glance, these views may sound a bit deviant, but if you think about it carefully, you will find that the words are exquisite, implying the core essence of the cycle of heavenly principles. It is similar to Luan Yi's "Original Wealth".

For example, Luan Yi said that he realized a set of theories from playing chess, which he called game theory, and there is a very typical example in the theory, the content of which is: there are two thieves arrested by the officials, A and B, but there is not enough evidence to convict them. The officers then imprisoned the suspects separately, met with them separately, and offered the same option to both parties: if one pleaded guilty and testified against the other and the other remained silent, the person would be released immediately, and the silent person would be sentenced to 10 years' imprisonment. If both remained silent, they were also sentenced to one year's imprisonment. If both of them report to each other, they will also be sentenced to 8 years' imprisonment.

Luan Yi calls this paradigm the prisoner's dilemma.

In this example, Luan Yi first makes the assumption that both prisoners are natural persons mentioned in Yuan Fu, that is, ordinary people who are oriented towards "self-interest" thinking, that is, they both seek the best self-interest and do not care about the interests of the other participant. If the benefit of a participant in one strategy is lower than that of other strategies in any case, this strategy is called a "strict disadvantage". Rational participants never choose. In addition, there is no other force to interfere with individual decision-making, and participants can choose their strategy exactly as they wish.

Which strategy should prisoners choose to minimize their personal sentences? The two prisoners were incommunicado and did not know each other's choices; And even if they can talk, they may not be able to trust each other not to talk back. As far as an individual's rational choice is concerned, the sentence for reporting betrayal is always lower than silence. Imagine how two rational prisoners in a dilemma would choose:

If the other party is silent and betrayal, I will be released, so I will choose to betray.

If the other party betrays and accuses me, I will also accuse the other party in order to get a lower sentence, so I will also choose to betray.

Both of them face the same situation, so their rational thinking will come to the same conclusion - choose betrayal. Betrayal is the dominant of the two strategies. Therefore, the only common denominator that can be reached in this game is that both participants betray each other, and as a result, both men will serve 8 years in prison.

Luan Yi's explanation of game theory and the prisoner's dilemma made Lu Zhi stunned and speechless for a long time. After pondering the content for a while, I felt more and more reasonable. Let Luan Yi speak more deeply.

Poor Luan Yi did not have a deep study of mathematics in his previous life, and he only had a general understanding of game theory, so he could only say that his research on game theory was still in the initial stage, and there was not much to teach Lu Zhi.

Lu Zhi looked a little disappointed, and then relieved, how old Luan Yi is, but he is only 17 years old, and it is rare in the world to have such an understanding. Thinking of this, Lu Zhi's eyes suddenly lit up, "Such an achievement at such a young age?" Then when it comes to the year of establishment, will it be repaid? ”

Since then, the communication between Lu Zhi and Luan Yi has become closer and closer, and most of them are Lu Zhi talking and Luan Yi listening.

Luan Yi vaguely felt that Lu Zhi wanted to teach what he had learned all his life, but he had already worshiped under Cai Yong and could no longer worship Lu Zhi as a teacher.

Lu Zhi didn't care about this, even if he didn't have a master-apprentice relationship with Luan Yi, he still instilled in Luan Yi what he had learned all his life all day long. Luan Yi was dizzy all day long, and couldn't help but recall the days when he was studying at Yingchuan College.

There is always a time when the words are finished. Soon, Lu Zhi found that he didn't have much to teach Luan Yi, and his daily schoolwork gradually decreased.

The boring time grew, and the days became slower and slower day by day, but Wang Yun's oral training said that Emperor Ling still had no intention of interrogating him.

In desperation, Luan Yi had to find a way to polish his time, so he asked the cell boss to prepare a game of Go and play against Lu Zhi.

But that Lu Zhi's chess skills are really superb, and he doesn't know at all that he will let the juniors kill more than a dozen games in a row, all of which ended in Luan Yi's fiasco.

If you win, you win, and you always put on a smug look.

Luan Yi was furious, thinking about how to avenge this year's revenge. After thinking about it all night, he came up with a plan, drew a sketch overnight, and handed it to the cell boss, so that the cell boss could find someone to make it according to the map as soon as possible.

After half a day, a pair of chess pieces that were still fragrant with lacquer were placed in the middle of Luan Yi and Lu Zhi.

Chess as a "new thing" in the Han Dynasty, Lu Zhi naturally didn't know how to play, after asking about the specific way to play, he immediately saw that chess contained a deep mystery of the art of war, and couldn't help but praise Luan Yi, "Ziqi is really smart, he can come up with such a strange thing!" Let's talk about the next game first. ”

Luan Yi nodded happily. In the first set, Lu Zhigang knew that Ma Xiangri and Xianggotian were not very good at playing, and he was killed by Luan Yi and became the commander of the light pole. Luan Yi was overjoyed.

In the second set, Lu Zhi's situation was slightly better, but he was beaten by Luan Yi's afterthought.

Third Set ...... Let's not mention the third set.

"Will!" Lu Zhi stroked his beard and laughed, "The old man has won again!" ”

Luan Yi was dejected, and his hair bun made him scratch all over the place, "I can't play this chess!" "Breathlessly, he lay down on the bed and couldn't bear his head.

Lu Zhi didn't say much, and went back to the table to drink tea while holding a book and reading leisurely.

For a long time afterward, Luan Yi always regretted that he couldn't play a few more games with Lu Zhi that day. As for the reason...... Lu Zhi is gone.

After Lu Zhi was imprisoned, the imperial court worshiped Dong Zhuo, who was the governor of the state and the Taishou of Hedong, as the general of Dongzhonglang, and replaced Lu Zhi in Jizhou to pacify the Yellow Turban Army.

The funny thing is that one of the big defeats is also closely related to Wei Ning. After this guy served as the captain of the school, he escorted a batch of food and salary when he went north, and because he did not understand the military affairs during the march, he would not arrange the marching route, and he was used to being delicate, and he had not suffered the hardships of the long journey, and he stopped and stopped all the way, and repeatedly missed the Jiancheng City. As a result, the officers and men slept in the open all day long, and there were many complaints.

One day, as usual, the army did not have time to catch up with the next county town, so they had to camp in the field. It happened that there was a small river here, so Wei Ning asked his officers and soldiers to set up camp on the riverside, saying that it was convenient to get water next to the river, and the officers and soldiers could also take the opportunity to wash their bodies. The adjutant of the army stepped forward to dissuade him, telling him that it was taboo for soldiers to put tents along the river, and that if he was attacked in the middle of the night, there was no way out.

But no matter how he persuaded Wei Ning, he just didn't listen.

As a result, there was really a bandit attack that night. The officers and soldiers were defenseless, and the camp tents were lined up along the river, which was unorganized. was defeated by bandits, with countless casualties, and the food and salary were also robbed. Fortunately, Wei Ning has a good water nature, and he escaped from the water to ascend to heaven.

Pity this Wei Ning, the thief didn't see any of them, and he ended up annihilated. fled to Hebei, Dong Zhuo heard that the food was gone, and suddenly became a big one. What do you rely on to fight a war? It's a salary. Now it's good...... It's all gone!

Dong Zhuo was already angry after losing the battle, and now that the food is gone, he is even more angry. If it weren't for Wei Ning's fact that he was a member of the Wei family in Hedong, and Dong Zhuo happened to be concurrently in the position of Taishou in Hedong and had some friendship with the Wei family, he would have dragged Wei Ning out a long time ago.

However, capital crimes are inevitable, and living crimes are inevitable. Dong Zhuo slapped Wei Ning back to the capital again, and folded another letter, pushing the reason for the unfavorable war to Wei Ning.

Long Yan was furious and scolded Zhang Rang for finding something for him. Didn't you say that you can be as civil and martial as Luan Yi? This is called Nengwen Nengwu? This is called losing soldiers and money, and losing money. Emperor Ling scolded Zhang Rang for a bloody squirt, so frightened that Zhang Rang knelt on the ground and trembled, and didn't even dare to reply a word. watched Emperor Ling take away Wei Ning's position as captain. If it weren't for Luan Yi's need for him to come out and confront him, he would have been pulled out and beheaded.

Although Dong Zhuo put all the blame on Wei Ning's head, he didn't end up with anything. In April, Emperor Ling ordered Zuo Zhonglang to send Huangfu Song to Jizhou to replace Dong Zhuo and pacify the Yellow Turban Army. Huangfu Song lived up to expectations, beheaded Zhang Liang and more than 30,000 people, drowned more than 50,000 people when he fled to the river embankment, burned more than 30,000 cars, and captured a large number of people. And Zhang Jiao was broken and killed, and the head was transported back to Beijing. In the same month, Huangfu Song and Julu Taishou Guo Dian attacked Quyang, successfully beheaded Zhang Bao, and captured more than 100,000 people. The Yellow Turban Rebellion was completely quelled and returned triumphantly.

After Huangfu Song returned to Luoyang, he wrote to Liu Hong, giving Lu Zhi the credit for pacifying the Yellow Turban Army in Jizhou, and at the same time praised Luan Yi's achievements to Emperor Ling, and begged Luan Yi to be acquitted.

As a result, Emperor Ling Xu Lu Zhiguan was reinstated and still served as Shangshu. did not make a statement on the treatment of Luan Yi. Neither release nor trial.

Obviously, the emperor has not yet made up his mind in this matter, and he has a grudge against the Holy Mother Sect, and he can't bear to lose a talent like Luan Yi.

Lu Zhi was released from prison. When he was released from prison, he looked back at Luan Yi and said quietly: "When you come out, let's play chess and chess together." ”

Somehow, Lu Zhi was obviously expressionless and looked serious. But after hearing these words, Luan Yi suddenly felt that his eyes were sour, and he wanted to cry. He bowed slightly, and then turned his head and pretended to look out the window. It wasn't until Lu Zhi's footsteps spread farther and farther away, and after disappearing, he turned back to look at the tall back.

"It's really nice to be in such a place and make such a friend!"

Lu Zhi didn't feel anything when he was there. Sometimes, Luan Yi will faintly feel that this old man is very annoying, at least in terms of playing chess so that people don't hate it. But now that Lu Zhi is gone, and he is the only one left in the prison, he feels that it is more interesting to have the company of old guys, at least someone can talk to him, drink, chat, and play chess. As it is now, 'There are walls on all sides, and there is a man in the middle.' What did Lang do? Count the four walls. ’

was really panicked, Luan Yi had nothing to do, and compiled the knowledge that Lu Zhi taught him some time ago into notes for slow digestion.
