Cheng Yun studied honestly in Luoyang during this time, and studied with Yang Ci, Yang Biao, Han Shuo, Yuan Kui, Yuan Feng and others.

Although at the beginning he thought that it was okay to learn the strategy of the military formation and the strategy of governing the country, but this idea was severely criticized by Liu Zhan, and he also understood, in fact, in this Han Dynasty, he has mastered the general study of the scriptures and meanings, and can have the corresponding position of power, and can derive the policy of governing the country, although Cheng Yun does not understand the policy of governing the country in later generations, it does not mean that he does not know that it is right for others to put it forward.

There are many people who say that Wang Mang is also a person of later generations like Cheng Yun, but Cheng Yun only hopes that he is not, he is too stupid, and it is normal that he can't do some things by himself, just like he has never beaten Tian Yu alone, of course, it is not ruled out that one day Tian Yu will be old and he will not be able to beat him, but so far he has never won.

If you can't do something, let someone else do it, you know what it is, you can direct it, or order the person who will do it, you tell him what to do, not what you want to do.

Yuan Shu's side is, Yuan Fang's last wish Cheng Yun can only be a commander, a supervisor, can not be a practitioner, the practitioner Yuan Shu has been addicted to learning for more than half a year, and he can't extricate himself, every time Cheng Yun comes to him, he is learning from painstaking scholars, especially the "Book of Changes", he has a deep attainment in this, and he usually predicts cloud and rain weather, and the accuracy is not much better than that of Yuan Feng.

In addition to studying, Cheng Yun often pulls Yuan Shu to the martial arts arena to watch the people of the guard training competition, not to mention, the training ability Xu Rong is much stronger than Xu Shu, obviously the soldiers under Xu Rong's command are full of spirit and strong combat power, and it must be Xu Rong's side to take out a one-on-one advantage, but to talk about team battles, Xu Rong's department is too far away from Xu Shu's department, and it was originally quite methodical to interact with each other, but it was messed up by Xu Shu's abandonment tactics in a few rounds, so that Xu Shu's department won the victory.

However, Xu Rong also found a way to relieve his anger, that is, the fighting general, Xu Rong is older than Xu Shu, just like Tian Yu is older than Cheng Yun, every heads-up is Xu Shu's defeat, Xu Shu and Cheng Yun are different in that he will continue to accept the challenge next time he is challenged after he loses, and he will never get tired of it.

Cheng Yun felt that he was a sign of masochism, but Xu Shu sneered: "Do you think, if I don't accept his heads-up every time, he won't let his subordinates accompany me to practice the military formation, especially every time I win him in the military formation." One person, one game is the most suitable. ”

Cheng Yun had nothing to say, and silently mourned for Xu Rong in his heart, and he didn't know if it was a blessing or a curse to meet such a friend.

That is, to watch them perform martial arts, in order to make Yuan Shu excited, sometimes Yuan Shu also played a few tricks with Xu Shu in the martial arts arena, although he lost more and won less, but he was able to fight with Xu Shu with his strength, Xu Shu privately told Cheng Yun that he did not release water.

Oh, why didn't you choose Xu Rong for a move? Xu Rong's tricks are not like the competition between Xu Shu and Yuan Shu and their rangers, it is a horse fight, Xu Rong crushes Xu Shu in horse battle, and Xu Shu is not worthy of Xu Rong in foot combat.

Cheng Yun sometimes asked Yuan Shu to go to Yang's house, but Yuan Shu stopped going after going twice, not only because the Yang family was his father-in-law's house, he was very uncomfortable, but also because there was an existence that made his scalp numb, his brother-in-law Yang Xiu.

Yang Xiu is three years younger than Cheng Yun, and in terms of intelligence, Cheng Yun is far from being comparable, but Cheng Yun's knowledge is far beyond Yang Xiu's, so he can still deal with it, plus Cheng Yun has been improving, so for Cheng Yun, the Yang family is not a tiger's den in Longtan, but like a game show that answers questions and breaks through.

Yang Biao also likes to pamper this little son very much, obviously he is to train him as the head of the Yang family in the future, but if there is no Cheng Yun, he will be killed by Cao Cao directly, thinking of this, Cheng Yun has to shake his head, the child still can't be too used to it.

Yang Ci also thinks this way, recently Yang Ci is idle at home, basking in the sun every day, Cheng Yun came to talk to Cheng Yun about current affairs, and lectured on scriptures for him, and the two became New Year's friends.

On this day, Yang Ci was telling Cheng Yun about "Ouyang Shangshu", and Yang Xiu, who was uneasy, came out again, I have to say that Yang Ci first had Cheng Yun Zhuyu in front, and his love for Yang Xiu was relatively normal, rather than doting, so Yang Xiu's growth environment was still quite good.

Yang Xiu didn't dare to be presumptuous in front of Cheng Yun, this big brother belonged to his peers, and he couldn't get the protection of his parents when he taught himself, and if he made a mistake, he grabbed the handle, and he had to clean it up.

However, this erudite brother is still quite loved by Yang Xiu, and he doesn't like to answer when asked by the knowledge of orthodox literature and scriptures (in fact, Cheng Yun's mastery is only a little stronger than Yang Xiu's, and he is afraid of going off topic), he can say four or five to six of those bizarre things, and the most important thing is that his grandfather and father are convinced by this, and it is difficult to refute.

"I met my grandfather and Brother Wen Ying." Yang Xiu's rules and regulations, thanks to Cheng Yun, Yang Xiu since the age of three began to study, there is a table word Dezu, according to Cheng Yun's crooked heresy, the reader should have a table word to set off, although this heresy was criticized by Yang Ci for a long time, but Yang Xiu's word Dezu was still finalized by Yang Ci.

"Dezu must have a funny question to test me when he came." Cheng Yun smiled, "It's better to answer this question according to the previous habit, you answer it first, and I'll answer it later." ”

Yang Ci nodded, "You little slippery head, every time I say something right, you applaud on the side and don't express your opinion; When you don't say the right thing, say the right thing. ”

"You did this, so that Xiao Dezu felt that you were much stronger than me, and now the majesty of my grandfather can't be revealed." Yang Ci laughed, but did not refuse Cheng Yun's suggestion, "What's wrong with Dezu?" ”

"Well, that's the case," Yang Xiu first explained that today he broke a very good-looking celadon that Yang Ci also loved very much, and before the next person saw it, Yang Xiu told Yang Biao about it and asked Yang Biao if there was a way to restore the broken celadon.

Yang Biao was so angry that his beard curled, "It's all broken, how can it be restored?" Even if it is glued, there will be cracks. I'm not omnipotent, it's useless to look for me for this kind of thing, you go and apologize to your grandfather yourself. ”

"I thought to myself, since my father said, 'I'm not omnipotent,' why don't I find an omnipotent man to come and help me fix the porcelain? So, is there such an all-powerful person? ”

Before Yang Ci got angry, Yang Xiu relied on his own ingenuity to successfully change the topic, and this matter was notified to Yang Ci in the form of a declarative sentence, and he did not disobey Yang Biao's words, and counted them in one fell swoop, but the excitement in his heart didn't start for long, and he saw Cheng Yun with a wicked smile next to Yang Ci who was contemplative, and his back was wet and cold.

"In my opinion, no one is omnipotent and can do anything." Yang Ci stroked his beard and groaned slightly, "People can know the past and the present, and they can also predict the future generations, but when something happens, no one can let time go back, and it is difficult to even restore it to the original state." ”

Yang Ci suddenly seemed to think of something, "What did you just say?" Which of my porcelain did you break? Is that celadon? You, you, you! ”

Cheng Yun hurriedly calmed Yang Ci's emotions, "Sir, don't be too excited, it's just a piece of celadon, you know, it's impossible for the same to appear, but with the development of the times, there can always be a better celadon appear, I'll let someone help you get a better one these days, you have a flat mind, the question just now, your guess is still quite pertinent, can you prove it?" ”

When it came to academic issues, Yang Ci really put his mind at ease, and Yang Xiu was dumbfounded, this ability to change the topic still has to learn from Brother Wen Ying, and secretly gave Cheng Yun a thumbs up.

"Proof, as I just said, no one can stop the passage of time." Yang Ci frowned, "Although this explanation is far-fetched and a counterexample has been found, it can be proved after all, right?" ”

Cheng Yun shook his head, "If someone can stop the passage of time, then you won't know, don't you think?" Because time does not pass, human thinking will cease and everything will be in a static state. ”

"Tell me about it?" Yang Ci saw that he was confident, and he was very cooperative, I have to say that these old fritters in the officialdom are better than one another, and communicating with them is like a spring breeze, provided that they are able to understand their thoughts.

"This involves a new theory," Cheng Yun is there, "and I was also inspired by Zhuangzi and Huizi, and the debate of Hao Liang is worthy of philosophical enlightenment." ”

"Those who are good at debating are famous scholars, but what is philosophy?"

Yang Ci was stunned, and Cheng Yun was also taken aback, "Huh? Well, okay, philosophy is the name I gave it, that's it, Zhuangzi and Huizi are both famous thinkers, so this kind of thinker puts forward a very philosophical academic, I call him philosophy, this has a little to do with Taoist nomenclature, but it has little to do with it. ”

Seeing that Yang Ci still wanted to ask, Cheng Yun hurriedly continued to say what he wanted to say, "An almighty person is a person who can do anything, so what can't he do?" ”

Seeing that Yang Ci and Yang Xiu's attention was attracted, Cheng Yun continued: "We can not ask this question, we are not omnipotent, it is normal to have one, then ask the almighty person this question, and you will find that he is actually not."

Yang Ci suddenly realized and laughed, "Okay, you Cheng Wenying, it really makes sense, is this the philosophy you are talking about?" ”

Cheng Yun shook his head and said with a smile, "The scope of philosophy is too big, I call it paradox, an almighty person can't find something he can't do." ”

Yang Ci nodded, "I've learned, I've learned, you Cheng Wen should definitely one day let the entire Han cheer for you." ”
