Chen Fei said this famous foreign line with a tiger in his heart and sniffing the roses carefully, which immediately surprised Emperor Li Yuan. Because the poem is already so good, it feels like a perfect combination of masculinity and femininity. And this one yin and one yang are just a bit similar to Taoism.

The meaning of this poem is to describe a man who has a tiger-like ambition in his heart, but he will be attracted by beautiful things and immersed in this beautiful moment. Therefore, Li Yuan, who is not unfamiliar with literature, and even Princess Wanchun, was amazed by this poem. Of course, they would not think that Chen Fei's sentence is a poem, and this kind of vernacular poetry was not popular in ancient China. However, art has no borders, and anyone can experience that taste from this sentence.

"It seems that Chen Aiqing, you are in a high mood and have experienced the great way of nature of heaven and earth. I feel a little ashamed!" Li Yuan joked.

"I don't dare!" Chen Fei answered immediately.

Li Yuan continued, "Okay, are you here to show me new weapons today? Let me see, what new weapons have you brought for me?"

Chen Fei immediately opened the scroll on his hand, revealing a pair of drawings. On this drawing are several pictures he drew by sketching, and then presented them in front of Li Yuan and Princess Wanchun.

"Good painting!" Princess Wanchun was surprised.

"Good military formation!" Li Yuan said.

Li Yuan and Princess Wanchun have different perspectives on the problem, so the two sides feel different when looking at this painting. Princess Wanchun thinks this is a good painting, but what Li Yuan saw is indeed the problem of the military formation. The soldiers in these military formations are full of fortitude and loyalty, so Li Yuan was also moved by this painting.

"Your Majesty, I will explain to you the pulley crossbow I invented. I originally invented the pulley bow, but the pulley bow is not suitable for rapid shooting because of the hand feel when pulling the bow. I changed my mind and made this pulley crossbow. The pulley crossbow can be skewed on the hands of a person without any stomping on the feet. In this way, our shooting speed is countless times faster. In the past, the speed of an arrow can be shot out, but now it can shoot three or four arrows. In this way, our same bow and crossbow will increase the rate of fire by three or four times."

"Your Majesty, look, the second picture is a tactic that I discovered when I studied the books of my predecessors. This tactic can be called linear tactics. This tactic is made by crossbowmen, arranged in three rows, and then fired crossbow arrows in turn to fight against the enemy's cavalry. If the arrows are like rain, then the cavalry will be in trouble. At that time, we can cover the crossbowmen with spearmen, so that we can defeat enemy cavalry several times that of our own." Chen Fei said.

Li Yuan looked at the simulation diagram of these queues and asked: "Chen Fei, do you think this can restrain the enemy's cavalry? This is a difficult problem to defeat the cavalry in the past!"

Chen Fei immediately explained: "Emperor, this is not without limitations. This can only deal with cavalry without heavy armor. Your Majesty, you see, these crossbows can only face the light cavalry of the enemy. If it is heavy cavalry, it cannot be restrained. As for me, I can give an example, that is, during the Qin Dynasty, did the Qin Dynasty rely on powerful crossbow soldiers and then beat the Huns' cavalry to the death? But later, for some unknown reason, this tactic was lost. I still saw it in some ancient books. And I am confident that the firing speed and power of this pulley crossbow is no less than the powerful crossbows of the Qin Dynasty at that time, so I think this method is still feasible."

Chen Fei actually mentioned in later TV archaeological documents that the Qin Dynasty had actually started shooting crossbows with triscattered shooting against enemy cavalry. The reason why the Qin Dynasty could defeat the Huns many times was that such powerful crossbows were inseparable from it. Therefore, Chen Fei learned and sold it now and used it to fool Li Yuan. Chen Fei was also confident that his pulley crossbows would definitely not be worse than those of the Qin Dynasty. History is progressing, and the Tang Dynasty's crossbows would definitely not be worse than those of the Qin Dynasty.

Of course, this tactic can only deal with the nomadic peoples in the north, because the nomadic peoples in the north do not have heavy armored cavalry. If it were heavy armored cavalry of the Han people, this tactic would not be useful, so it still has certain limitations. However, Li Yuan was also very satisfied. This crossbow formation had already made him very satisfied. Now the Tang Dynasty is about to unify the world, and their opponents are no longer the separatist regime in the country, but the Turks in the north. The Turks in the north are no longer different from the Huns in the past. Now the Tang Dynasty has just been founded and is still in its early stages, so there are not many cavalry. Therefore, this method of using infantry to restrain cavalry is extremely precious.

"Okay!" "Okay!" "Okay!"

Li Yuan said three words "good" in a row, and was obviously very happy. This time Chen Fei gave him another surprise, which made him feel that the Tang Dynasty was not so hopeless in fighting the Turks. Although the Tang Dynasty had received support from the Turks, now that the Tang Dynasty unified the world, the Turks were destined to be enemies of the Tang Dynasty. Next, they had to deal with the Turks. This method could allow infantry to defeat the Turks, which was a good way.

"Chen Fei, what reward do you want? I just awarded you the title. You are not suitable for promotion for the time being. I don't know where you should go at the official position. Do you want to go to the military weapon supervision?" Li Yuan asked.

"Emperor, I do not ask for the emperor to be promoted, but only seek to work for the emperor. This is my honor. As for the military weapon supervisor, I don't want to go, because I hope to be by the emperor and guard the emperor at any time." Chen Fei said.

Now that Chen Fei is forced to join the gang by Changsun Wuji, of course it is impossible to go to the military weapon prison. If Chen Fei goes to the military weapon prison, who knows how that guy Changsun Wuji will deal with him? Therefore, it is better to stay in the left prison guard. Moreover, the military weapon prison is a department that is often laid off, so Chen Fei will not be foolish about going to the military weapon prison. If he is laid off at that time, where can he become an official? Even if the court solves the organizational problem, he will probably be left alone to support himself by himself. Although Chen Fei wants to live a life, he will not have to think about supporting himself when he is in his teens!
