Mutter...... Damn it! Gao Gan was a little angry, he didn't think about the situation of the rocket, and at the same time considered that the other party would use oil, so he asked the soldiers to prepare some sand, as long as the other party used the rocket, he would directly bury it with sand.

Who knew that the other party used a slingling to throw a glass jar filled with fish oil, and then fired a rocket at the first time, the fire spread so fast that the sand was too late, and the siege equipment was completely covered by flames.

Sure enough, with the development of the times, there are more and more means, and the means that I used to think were powerful are gradually losing their effectiveness. It's a pity that the talent of the senior cadres is not high, and it is really impossible to take into account such a profound situation.

"Looks like you don't have the means to siege the city anymore?" Liu Bao looked at Gao Gan with some disdain in his eyes. Without the means to attack the city, no matter how elite the Xiongnu soldiers were, they couldn't run to the city!

Run? Liu Bao suddenly thought of something, mainly the appearance of the ramp of the ladder truck just now, which he remembered vividly. If he could construct such a ramp, even if it was not very high, almost to the right or so of the city wall, then he could take the cavalry and jump on the head of the city and let the horses run on the top of the city.

"Sandy soil...... That's right, sand! Thinking of this, he also remembered that earlier, there were soldiers who planned to use the sand in their pockets to extinguish the flames of the siege equipment, but the fire spread too quickly and had to give up.

"I'm sorry, but it will take some time to rebuild the siege equipment." Gao Gan was helpless, especially when he knew that there were still enemies around, so he had to consider whether to withdraw from the surroundings of Lin Xi County first, and then launch an attack after the preparations were completed.

"Forget it, you don't need to provide siege equipment!" Liu Bao quickly made up his mind, "You prepare a large number of pockets for me, and then mobilize the soldiers to fill them with soil, a large amount of soil!" ”

He took a closer look at the city in front of him, the city wall is not high, three or four meters away, if it is built up at this time, it will only take about three meters, he is sure, and he jumps on the city wall with the cavalry.

For a three- or four-meter soil slope, only enough soil is needed, and it is not a big problem, and tens of thousands of people take turns pouring soil, and they will soon be able to build up.

"King, are you going to ......" Gao Gan was still a little unable to react.

"You don't need to ask why, since you can't attack the city, you might as well leave it to us! If you want to take down this city, do as I say, immediately, immediately, and don't ask why! Liu Bao shouted directly.

"Okay, I'll get ready! Immediately! Gao Gan didn't know what the other party had planned, but the other party wanted to do it, so help him prepare, so he should go back and order, let the baggage soldiers, and prepare a large number of pockets.

On the city wall, seeing that the other party had retreated, Chen Zhi frowned: "General, it seems that the other party has other plans......

"I know, but we can't go out of the city to fight, we just want to attract the attention of the other side here, and then create opportunities for our allies!" Cao Ang replied.

"If you calculate the time, in order to conserve your strength, even if you borrow the gallop of the Wanshiwu for us, it will take a day to come over, but the Xiliang Iron Cavalry in ambush near our Black Mountain, and the Tiger and Leopard Cavalry in ambush on the side of Lin Shu Mountain, will arrive in two hours." Dong Zhao calculated the time.

"Two hours, I hope we can hold on for two hours!" Cao Ang looked at Chen Zhi and Zhou Cang.

"Peace of mind, as long as the subordinates still have a breath, they will definitely ensure that the city is not lost!" Chen Zhi promised, of course, he didn't forget to throw a wink at Cao Ang. Obviously, he seems to like Cao Ang a lot.

"Well, that's a hard ......" Cao Ang snorted, and then reluctantly replied. Chen Zhi is actually good, his martial arts are very good, he is good at training, and he also has the ability to command troops in battle. However, it is obviously a reverting species, and there is also a habit of dragon yang......

If you want to talk about ordinary men, they are handsome and beautiful, even if they have the habit of dragon yang, they are actually quite pleasing to the eye. But when Chen is like this, it's a bit unbearable.

Speaking of which, after an hour, thousands of bales of sand and soil have been assembled. It was not until this time that Gao Gan knew Liu Bao's thoughts, and while feeling that the other party was a genius, he also began to be vigilant.

The Huns had already begun to think about how to conquer the cities of the Han Dynasty without using siege weapons. If they are allowed to go back, then if they become hostile to them in the future, then it is estimated that they will also face danger in the counties of the state.

The solution is nothing more than three, either he will always be friendly with the Huns, this is almost impossible, but it doesn't matter, as long as he can be transferred away before the fight, anyway, his family is not in the state; Either don't let these 10,000 Huns go back, it's just that this idea is a bit unlucky, especially if you make a move, as long as you let one person escape back, then Yuan Shao will be a sinner even if he has a bad relationship with the Huns.

The last and last resort is nothing more than to raise and thicken the walls of all the cities. It's just that the cost is too high, and the construction period is slow. After the construction is completed, it is also someone else's political achievement, and it is a lot of county orders, and I don't like this kind of project very much.

"Let's go, let the Han army in the city tremble!" Liu Bao didn't know what Gao Gan was thinking, and at this moment, he waved his arms, and the various departments that had already received the order rushed towards the direction of the city wall.

At that moment, to be honest, even Cao Ang felt that the other party was crazy, could it be that the other party's horses could rush to the city wall? Otherwise, what's the point of such a large-scale attack?!

As a result, when the other party came over, he found out the other party's intentions! The first 1,000 people poured the earth with sand and gravel around the city wall, and then turned around and left. Then the second batch, the third batch......

The choice of sand is very important, and the sand of the base must be mixed with sand and gravel, so that the ramp can be tamped. Then you can't mix sand and gravel on the upper runway, after all, there is no horseshoe, and if you accidentally step on a sharp stone, then it may make the horses stumble, and even affect the soldiers above.

"General, it seems that the other party is planning to use the method of building earth to build a ramp, just like a ladder truck!" Zhou Cang quickly realized what the other party was thinking.

"It's a powerful idea, and in this case, our oil will hardly be effective." Dong Zhao thought about it, whether it was time to attack the city in the future, he could also use this method. After all, as long as you can attack a city, it doesn't matter who invented it.

At most, due to the relationship between heaven and harmony, less use of methods such as throwing rotting corpses into the city to create a plague.

"The question is how we should deal with it now, if we let the other party build dirt like this, then the other party can really run on the city wall!" Zhou Cang was a little flustered.

"Didn't the research start shooting back?" Cao Ang was on the city tower at the moment, watching the archers already start to fight back.

"The problem is that the other party is also shooting in cover, and the opponent's archery is no worse than ours!" Zhou Cang retorted.

Sure enough, near the city wall, a large number of Hun soldiers were constantly roaming, as long as they saw the archers outcropping, they would bend their bows and shoot at the city wall. These guys have been hunting on the grassland since they were children, and their archery skills are really good, and most of them can hit, so that the archers don't dare to show their heads. In such a situation, it is no wonder that Zhou Cang is a little flustered......
