The reason why Sima Yi in history was suspicious of Cao Cao was because Cao Cao had a dream of a three-horse trough, and secondly, because Sima Yi had the appearance of a wolf, so he was suspicious of him.

The so-called wolf Gu Zhi does not actually refer to appearance, but to a habit of the wolf. When the wolf walks, it will always look left and right or look back. And because the wolf is the totem of the Hu people, the Central Plains people are very disgusted with wolves, and finally use this behavior to describe a person who is cautious and suspicious and has bad intentions. However, in the historical records, the wolf Gu Xiang also annexed the world, but it also had the meaning of worries.

In his previous life, he thought that the appearance of the wolf Gu actually meant that a person looked like a wolf. At that time, Li Yi was still very puzzled why Cao Cao was suspicious of the other party because of a person's appearance, but he didn't think much about the fact that Cao Cao snubbed the other party because Zhang Song was too ugly. Maybe for Cao Cao, appearance equals justice?

But now, after understanding the true meaning of Wolf Gu Zhixiang, Li Yi has a new understanding of this matter, "I think it's because the suspicious Meng De maliciously demonized Wolf Gu Xiang after perceiving Sima Yi's talent and ambition, and finally came to the conclusion that Sima Yi has the ambition to annex the world, and he is insidious and vicious, which is the worry of his Cao Wei regime......"

And because of this, Li Yi is still very curious about Sima Yi, after all, he has never seen a person walking back and forth left and right or even looking backwards. Because in Li Yi's brain, this kind of person should be no different from a neuropath.

It's just a pity that the facts disappointed him, Sima Yi, who came with Sima Lang, did not show the so-called wolf appearance, and behaved very respectfully and well-behaved from beginning to end.

If there is anything different, it is that Sima Yi's eyes are very bright, giving people a feeling of "this kid has his own ideas". Moreover, he is not like his brothers, who will show his fear of Li Yi from time to time.

This kind of performance is very familiar to Li Yi, like Guo Jia when he was a child, well...... It's not cute! Well, Li Yi was actually the same when he was a child, but Li Yi didn't really want to admit it. Because he felt that he must have been the kind of cute and cute little Zhengtai when he was a child, otherwise how could he be so handsome now?

Later, Li Yi took another six exams, although they were still very young, and the eldest Sima Yi was only twelve years old. And in addition to Sima Yi, the other five Li Yi are also very unfamiliar, or they have not left any deeds worthy of reference in history at all. But since they can be collectively called Sima Bada, Li Yi still has high expectations for them.

And the results also made Li Yi very satisfied, except for Sima Yi, everyone else's performance was very good, it can be said that if the current court is still the previous court, then they are all qualified to enter the children's department.

"Boda, you can send Ah Yi and them to Wushuang City first, and then go to Qiuzi." Li Yi said with a smile.

"Thank you, Lord." Sima Lang naturally understood Li Yi's subconscious meaning, that is, he wanted Sima Lang to accompany Sima Yi and the others more. After all, in the future, Sima Yi and the others will be in the Wushuang Kingdom, and Sima Lang will stay in Shangjun, and God knows when they will be able to see each other again.

In addition to various government affairs, he often invited Ma Ming to inquire about the research and development of various instruments and weapons.

This Ma Ming is one of the craftsmen who came after seeing Li Yi's recruitment notice. After assessing his skills, Li Yi directly appointed him as the Sima of the Ministry of Works, and led many craftsmen under his command to develop various instruments and weapons for him.

Well? Sounds similar to the treatment of craftsmen in the past? Well, although it sounds the same, it is actually completely different, because Li Yi not only gave them the same status and privilege as ordinary officials, but also gave them freedom and respect that they had never had.

For example, in addition to the tasks assigned by Li Yi, he will not continue to let them perform other tasks, but let them research what they like on their own, and if they succeed and Li Yi also thinks it is good, he will give them corresponding rewards.

Of course, the most important thing is that because of the emergence of assembly line work, these craftsmen only need to do two things a day, research and teaching. Compared with the treatment of working every day under the oppression of the government before, and only getting a little bit of money, and even being monitored, it is simply a life that I can't dream of.

Therefore, Li Yi doesn't even need to supervise, these craftsmen will work hard every day to study and teach. Perhaps, the reason why Yu Rang in the Warring States Period in the past said the sentence that has been passed down through the ages, "When the countryman meets me, I repay the countryman" is like this.

With the support of Li Yi, these craftsmen are constantly studying various civilian and military instruments, but one of them is what Li Yi pays the most attention to, well...... Because he came up with it.

The building car, in Li Yi's description, is a kind of cart that can be pushed under the city wall, so that the soldiers in the car can directly enter the city wall. At the same time, it can also allow the soldiers below to constantly climb from the bottom of the car to the top floor, and the top floor can stand people. In Li Yi's opinion, this kind of thing is definitely a big killer weapon for siege! After all, isn't the reason why the siege is difficult is because the road from the city to the city wall is too difficult to walk?

If there is such a device, as long as it is pushed under the city wall, the soldiers can continue to rush directly to the city wall. In this way, the siege will become a very simple matter.

In the sketch drawn by Li Yi himself, the structure of this car can be said to be particularly simple, how to say? It is the kind of wooden frame that later generations built buildings, but it can be moved.

Strictly speaking, a movable wooden frame is not difficult in the eyes of Ma Ming and others, and even any craftsman can make it. It's just that...... The difficulty lies in the fact that this movable wooden frame not only has to be more than ten or even twenty steps high, but also has to be able to support the weight of at least dozens of people. Most importantly, it is easy to assemble and carry.

These can make it very difficult for Ma Ming and others to deal with it, and Li Yi doesn't have much to do about it. After all, he doesn't know anything about this kind of thing, huh? Does the school teacher teach? It's a pity that Li Yihe in his previous life was really unfamiliar with his teacher.

In addition to the building car, the idea of adding blood grooves to weapons has also been mentioned by Li Yiyi, science and technology are the primary productive forces, and Li Yike has never forgotten this. Although he couldn't get many epoch-making things because of his own reasons, after all, Li Yi didn't have so much capital to keep trying. But there are some things that can be roughly made by only needing to know what they look like, just like the cavalry three-piece suit and assembly line production.
