The army gathered in front of Dingtao City, but at this moment, a few dark clouds floated from the sky. Looking at the situation, it was afraid that it would rain soon.

"As expected, it seems that the situation is in our favor!" Cheng Yu looked at the sky, "Fengxiao was very accurate and could actually predict that there would be rain today!"

"Woo meow..." Because of Cheng Yu, everyone's eyes immediately turned to Guo Jia, who was very shy.

"Fengxiao, do you actually know the weather forecast?" Wang Yong stepped forward and patted her head gently. He thought that the only village man who could do this... Slowly, it was the village man or the village man who was still talking... Cough... I didn't expect Guo Jia would do it too!

"Hey hey..." Guo Jia was a little relieved after being hit by a few times. As for the weather forecast, the literal meaning is understood at once, but it is not difficult to understand. "Mr. Shuijing said, 'For generals, they do not understand astronomy, geography, qimen, yin and yang, geography, geography, yin and yang, geography, tact, tact, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury, treasury...'"

Speaking of this, he suddenly became panicked again. Just because when he was talking about this, all the generals immediately looked at her. After all, most of them did not understand this knowledge very well. Doesn’t this mean...

"However..." Guo Jia became a little panicked, "March to war...that, that...I...text..."

"However, when marching and fighting, the situation changes rapidly. Generals cannot be fully concerned. We civil servants should check for omissions and fill in the gaps. Fengxiao, what you want to express is this?" Cheng Yu said slowly. After all, the atmosphere is not very good. If you are not good, you will provoke a conflict between civil and military officials. The key is that she herself is also a general.

After she explained that the generals around her looked much better. Guo Jia's identity in the army was to join the army, and even the most grassroots civilian. She could also make suggestions. Generally, suggestions for joining the army were rarely listened to.

However, Guo Jia is different. She has potential. She was too shy before and couldn't even speak. She has improved a lot recently, so she brought it out. Otherwise, she would not even have the chance to join the army if she had changed her past.

As she said, the situation is ever-changing, and it is ever-changing. In this case, what's the use of bringing a civil servant who can't even say anything? Guo Jia, who once defected to Yuan Shao, was not even favored by Yuan Shao for this reason. Only Cao Cao was willing to believe in her potential...

In fact, it is also for Xun Yu's sake. On the one hand, she doesn't mind raising more idle people for Xun Yu. On the other hand, Xun Yu recommends that, and those who can make friends with Xun Yu must be not too bad talent.

It is precisely because of her specialness that Cao Cao could consider her suggestions, and at this time Cheng Yu came forward and advised: "It's okay to obey! If it really rains, it can not only ensure that there is no problem with the baggage, but the situation is also more beneficial to us. Even if it is wrong, it will just waste some time, and the benefits outweigh the disadvantages!"

Cao Cao made the decision and believed Guo Jia once, but he didn't expect it to rain!

"How are you preparing for the siege equipment camp?" Cao Cao immediately stood up and shouted.

"It's ready and can be put on the battlefield at any time!" Lu Qian stood up to respond.

"Surprise the city immediately!" Cao Cao pulled out his sword, pointed at the front, and immediately ordered, "Xiahou Yuan, Cao Hong is ready!"

"Lord has an order to attack the city!" Lu Qian did not dare to neglect and immediately issued an order. Four large cars began to advance forward behind him, and four more siege equipment were behind him.

Soon, four large cars separated, and two short cars appeared in the middle, but the style was amazing!

The top of the car has a roof and eaves, just covering the soldiers on both sides. There are four wheels at the bottom, and the soldiers can push and walk and backward. There is a log in the middle. The front end is wrapped in metal, which is ovate. This car is named after the log that wraps metal, and is called - Crushing Car/Crushing City Hammer!

Excluding big cities like Chang'an and Luoyang, ordinary county towns usually use door bolts to close the door behind; when going to the county town, winch is used to open and close the door, such as Puyang before. If the capital city Luoyang or Chang'an, there will be a broken dragon stone. Once it is put down, it will not be opened inside and outside, and it can only be violently destroyed. The key is that it is difficult to destroy!

Dingtao belongs to the big city and uses a winch switch. However, with these two rushers constantly colliding, there is still a chance to break it!

Speaking of which, the four two big trucks began to move towards the city wall and divided into four strands. The mechanism on one side slowly rose, and part of the long ladder slowly rose from the folded state, forming a long ladder-shaped one with the other part at the lower end.

There is also a turntable on the body of the car, which can be rotated up and down as needed, adjust the long ladder up or down, and finally put it on the city wall to form a step ramp, allowing two people to go up side by side. This car is therefore named - Cloud Ladder!

The last thing to approach is a platform built on a chariot. The platform is divided into three layers, up and down with a long ladder. Soldiers climb to the three-story platform, either lower than the city wall or higher than the city wall, can shoot arrows, transport soldiers, and be high to cover the soldiers below. This car is famous - the well railing car!

There were more than a dozen soldiers, in groups of three or three, holding a long ladder with hooks on the long ladder, which could be firmly hooked on the city wall. The soldiers used this as a helping force to climb upwards and finally climbed up the city wall.

This thing is very simple to make and can even be used locally. So if you march quickly, you can temporarily make this long ladder as a means to climb the city wall. However, because it is very fragile, the user must bear greater casualties!

As for rushing cars, well railings and ladders, they are bulky and can easily drag down speed in the army. If it were three hundred years ago, it would be inconvenient to march with these siege equipment, especially when the road is difficult to walk.

Later, Wanshiwu proposed standardization of components, so the standard parts of the production office, from that time on, the siege equipment was disassembled and transported, and then assembled at the destination. The benefits of building standardization are highlighted here, and the components can be replaced at will, and disassembly and assembled will not cause the siege equipment to be unable to be used again.

"It's raining..." Wang Yong felt the feeling of raindrops falling, and looked up and found that the raindrops had already begun to fall again.

"The rain will cause the enemy to be unable to smoke, boiling water or gold juice, and rockets to destroy our siege weapons. The only disadvantage is to make the siege weapons wet and cause slippage, but this can be ignored! In other words, the situation is beneficial to us at this moment of siege," Cheng Yu smiled faintly, "The only thing that needs to be worried is Lu Bu!"

Indeed, with Lu Bu's means, she was afraid that many siege equipment would be fake.

"So the lord has an order!" Cheng Yu's mouth curled up slightly, "If Lu Bu goes into battle, Dian Wei and you will go and hold her back!"

"Didn't you say you didn't take the initiative?" Wang Yong immediately protested.

"But if we fail to siege the city, or even lose troops, is it really good?" Cheng Yu didn't plan to let him go, "And didn't you look down on Lu Bu very much before? Since that's the case, what's there to be afraid of?"

Well, it seems that I pretended to be too much before, so others directly used this as a basis to retort! What else can I do? I can't say to her, "I was so scared that I was so scared that I just held on and didn't say it out."
