This is the ground-to-air guided cannon that made Liu Ye famous at home and abroad for a while, and was called "Thunderbolt Car" by Yuan Shaojun. Commonly known as, well, those who are illiterate and have a low grade are also called catapults. However, what is less known is that Guo Jia has another name for it, which is also a name that is truly recognized by Liu Ye, the maker. That's right, the Thunderbolt has an official name - the Armstrong Slalom Acceleration Jet Armstrong Cannon! This degree of restoration is really high, hey.

Obviously, just like the Pythagorean theorem and Newton's first law, in Liu Ye's heart, this kind of completely incomprehensible, but when he heard it, he felt that it was very powerful, and it was the real high-end and high-grade name! Therefore, after hearing Guo Jia say this for the first time, Liu Ye, the inventor, immediately recognized such a name. Cut, what kind of thunderbolt? It's so shallow.,When you hear it, it makes people feel like that.,It sounds like my "Armstrong Roundabout Acceleration Jet Armstrong Cannon, this degree of restoration is really high, hey" domineering?!

That's right, read that right. Although Guo Jia named Liu Ye's catapult "Armstrong Roundabout Acceleration Jet Armstrong Cannon", because when Guo Jia said this, he would always subconsciously follow the sentence "This degree of reduction is really high", so Liu Ye, who didn't understand it in the first place, naturally added this sentence to it, and the more I couldn't understand it, it showed that this grade was getting higher and higher!

Because Liu Ye is the maker of this catapult, therefore, to be precise, the official name of this catapult is actually - the Armstrong Roundabout Acceleration Jet Armstrong Cannon This degree of restoration is really high. (Thunderbolt cries)

Well, this story also tells us that forcibly changing a liberal arts student into a science student. In fact, there is a lot of risk. Parents and future parents should pay attention, they don't want their children to become like Liu Ye. But you have to be cautious!

Ahem, anyway. Liu Ye built a catapult and successfully counterattacked Yuan Shao's high-platform arrows, so that Yuan Shao could not dominate the air power, and returned a clear sky, this day, it finally stopped raining.

In this way, Yuan Jun no longer dared to climb high and shoot arrows. So, the trial made another plan, and sure enough. Under Yuan Shao's command, there is actually no shortage of talents at all, and there are more people with good brains. Proposal for trial: Order the soldiers to use shovels to secretly dig tunnels and penetrate through Cao's camp, called the "Digger Army".

Air combat doesn't work, so the trial will start to play tunnel warfare. Tunnel warfare, hey tunnel warfare, ambush millions of divine soldiers, hey ambush under millions of divine soldiers. If Guo Jia was also in Yuan Shao's camp at this time, he would definitely be amazed. Isn't this guy really from time in time? It simply gives Guo Jia the illusion of fighting across the ages.

So here, Guo Jia, who has been making soy sauce, finally played a little role. That's the reminder! said that it was a little, it was because Guo Jia was just moving his mouth, in fact. Guo Jia still plays a considerable role. Don't forget, when Yuan Shao beat Gongsun Zhan. But they dug tunnels. It can be said that Yuan Shao's "digging army" is already very professional. There has been a successful practical experience.

Gongsun Zhan was building Gao Lei at that time, he was in a high place, and there was a lookout outside but he couldn't notice the problem, if Cao Jun didn't deliberately pay attention, how could he find the clue? Especially before Yuan Shao had built a high platform outside and carried out civil engineering, even if Cao Jun accidentally saw some mounds or something, it was easy to ignore the past, right?

So, don't look at the only sentence in history Cao Bing saw Yuan Jun digging a pit behind the mountain, in fact, it is far from that simple, Yuan Shao's secret military and strategic actions, is it what you can see if you want to see it? Yuan Shao was so careless? Just find something to cover it up. Only by deliberately probing can we discover such subtle problems. Therefore, this can reflect the importance of Guo Jia.

So Guo Jia took the initiative to find an opportunity to remind Cao Cao, showing that he still existed, and he was still paying attention to the battle situation, and he was not completely playing soy sauce. And because Yuan Shao had already used this trick before, now that Guo Jia suddenly reminded him, he would not feel abrupt at all, and it would not make people feel inexplicable.

As a result, Cao Cao had a cautious mentality, this kind of thing would rather be believed than not believed, and sent someone to investigate, and really found a problem! For a while, the atmosphere of "Guo Jia is really a god and a man" was set off again, and it was said that coincidental things can not be repeated, but they can not be three, who can keep "crow's mouth" like Guo Jia! Otherwise, it may also be that the base number itself is large, for example, everything is said, and any possible situation is considered, so the more times it is said, the more situations in the statement will naturally increase, but is Guo Jia like this? No! Guo Jia often said it suddenly as if it had a flash of inspiration, and then suddenly hit. Although Guo Jia is usually very talkative, but in terms of reminding prophecy, Guo Jia still says relatively little, which makes people wonder, does this guy really have a destiny?

In the face of Yuan Shao's tunnel battle, Cao Cao asked again, what should I do? What if you know they're digging? I don't know where the other party will dig it out in the end. And, what if you hold one point, but in fact the enemy has a few points? As long as there is chaos in the camp all of a sudden, Yuan Shao will take the opportunity to cooperate with the outside again, and it will be strange if the Cao army will not be directly defeated at that time! This really gave Cao Cao a feeling that he couldn't guard against it.

There is no way, the disparity in strength makes Cao Cao have a lot of things that he wants to do but can't do, just like watching the other party build a high barrier before, Cao Cao can't stop it if he wants to. It's the same now, knowing that the other party is digging a tunnel, he can't rush out to stop it. Can we just move out of here and camp in another place?

Although that made Yuan Shao's "digging army" useless, Cao Cao's manpower and material resources were greater. Moreover, when changing camps, when building new camps, once Yuan Shao's sneak attack was encountered, it was unimaginable. Even if it succeeds, what if Yuan Shao comes to dig the tunnel again? Do you continue to change? Can you still retreat all the way to Xu Du like this?

In this regard, Guo Jia was silent again, although he knew what he could do, but he still left it to Liu Ye to perform. You can't put all your eggs in one basket. Since all the credit is on him Guo Jia, he will be high, so find someone to share it, maybe his Guo Jia's personal aura is a little less, but in fact, he does not lack such a point, on the whole, this will be better. Of course, the premise is that Liu Ye is absolutely reliable, and Guo Jia can definitely trust Liu Ye.

So Liu Ye proposed to Cao Cao that he could dig a long trench around the camp, which was equivalent to digging a moat. Although this project is very large, Cao Cao's side is more just laborious, and Yuan Shao's side is time-consuming to dig tunnels, and it can't be done by too many people. The soldiers are on the mountain, and they are stoned; The soldiers are in the ground, and they are protected by water. Liu Ye's strategic thinking can be described as quite ingenious, of course, this requires science and engineering knowledge as a basis. Tut-tut, this is the realm of superiority!
