According to the original design, the heavy trebuchet could load a hundred pounds of stone and throw it. Of course, you can also load 120 pounds of gravel and throw it.

When tackling key problems, there is no point in crushing stones, so the ten trebuchets are used with hundreds of pounds of stones. Of course, it is impossible for the army to carry thousands of pounds of stones around, but the stone thing can be completely made from local materials.

Even if you can't find a hundred pounds of stones, two fifty pounds can be improvised.

That is to say, the last dozen or so stones of dozens or hundreds of catties were thrown out like this, and then fell towards the sloping valley pass. It was as if it were a meteorite falling from the sky.

When testing this kind of heavy catapult before, Liu Tao also joked: artificial weakened version of meteor shower.

In fact, if you find oil, refine it into gasoline, pour it on a stone, and ignite it before it is ejected, you may be able to create the feeling of a meteor shower.

But forget about the big rocks, if it's the kind of gravel, you can try it. The kind is mainly used for siege, mainly for the soldiers defending the city, as well as the buildings in the city.

The stones fell and smashed against the wall, and the destructive power of the heavy trebuchet on the rammed earth wall was quickly manifested.

I saw a large piece of the wall, which slowly peeled off. A dozen stones went down, and the entire wall became potholed and crippled. As if it only took a second round of bombardment, it would collapse completely.

"What's that?" Yang Ang on the city wall looked into the distance in disbelief, the ten huge catapults seemed to have become monsters in his eyes at this moment.

"It's supposed to be a kind of stone thrower, but it's more powerful and the stones you can throw are heavier!" The adjutant next to him hurriedly explained, "General, if we can't destroy them before the second round of projectiles, I'm afraid that Xiegu Pass will be destroyed first!" ”

The implication is to let Yang Ang make a plan early, whether to retreat, or to fight, he must make a decision quickly.

But Yang Ang has no idea, it will definitely not work to go out to fight, the Han army is really good at spells, unlike his own side is completely parallel goods; If he doesn't go out to fight, he is not Yang Bai's descendant, and if he flees in battle, Yang Song probably won't protect him.

The Yang clan in Hanzhong is actually in the army, and his influence is much higher than that of Zhang Lu. At the same time, Zhang Lu was able to gain a firm foothold in Hanzhong, which was actually the help of the Yang family.

Among them, Yang Song, the head of the Yang family, served as the mastermind under Zhang Lu, and Yang Song's younger brother Yang Bai was a general in the army. In addition to the lineage, in the side lineage, Yang Ang and Yang Ren also served in the army.

It can be said that the Yang family controls the army and the family, while Zhang Lu controls the civilian officials and the common people, and the relationship of cooperation between the two sides is greater than the subordinate relationship.

The problem is that even if it is a cooperative relationship, as a general in the army, he escapes from the battle, so Zhang Lu has no way not to pursue it. Otherwise, if he can escape, won't the other Yang disciples be able to escape? Everyone is running away, who will deal with the Han army?

"Fight, switch, follow me!" Yang Ang weighed it, he would rather be a martyr who died in battle than a coward who escaped from the battle, in this era, reputation is really too important.

The opportunity to surrender has been missed by the group of pigs above, when he was in the army, when he knew about it, Zhang Lu had officially replied to Dahan and refused to surrender.

I don't know where Zhang Lu or Yang Song got their confidence.

According to the Great Han, if you don't surrender at that time, then you can only kill without mercy. Surrender is also death, and death in battle is also death, so it is better to die a little face.

"Meng Qi, I'll leave it to you!" Seeing that the other party opened the door to fight, Zhao Yun shouted behind him. Zhang Yan has to be on guard against the barbarians that may appear around him, so it is not good to leave casually, just let Ma Chao behave.

"It's been too long!" Ma Chao was obviously a little impatient to wait, and immediately led the army to kill him when he heard the words.

He led the orthodox Xiliang Iron Cavalry, and generally there would be one horse when marching, but when charging, he would change to another horse. Before the battle, Zhao Yun also asked if he wanted to bless the spell, but he refused.

In Ma Chao's opinion, there is no need to waste spells on the garbage in front of him.

"What is it ...... young people" Looking at the excitement of Ma Chao leading people over, Zhao Yun smiled faintly, after all, Ma Chao is only twenty-one years old this year, and he is indeed young.

"But the general hasn't aged much, it's not good to be so old-fashioned." Zhang Yan teased.

The two have known each other since they were children, after all, they are both from Changshan Zhending County, and they are considered fellow villagers. According to the principle of the township party in this era, the two should belong to the same faction in Dahan.

In fact, both of them belong to the faction in the early days of Liu Tao's career. It is different from the Cao Cao faction, the Yingchuan faction, the Bingzhou faction, the Yanzhou faction, the Youzhou faction, the Liangzhou faction, the Xuzhou faction and the Jingzhou faction.

The oldest faction of the old ministers of the Han Dynasty, with the retirement of Huangfu Song and others one after another, has almost lost its influence. The older generation will gradually retire after all, and those who remain are young and energetic.

"As the main general, I can't break away like an ordinary young man." Zhao Yun replied, originally the two had been hostile, but later he didn't expect that Zhang Yan had defected to Liu Tao very early. The two met again a few years later, and they were already colleagues.

So the relationship between the two sides eased slightly, but due to the different defense areas and a little deliberateness, the two did not become too close. In other words, they all deliberately avoid each other.

"You're going to be bored...... Having said that, when we met before, how did I see that chick, it seems to be interesting to you......" Zhang Yan quipped.

"Oh, Ma Chao's sister?" Zhao Yun also remembered that girl, and she really liked to surround herself. At least I'll find an opportunity to get close from time to time.,It's lively and cute.。

"Looks like you've noticed her too?" Zhang Yan was a little surprised, "Have you ever thought about marrying the Ma family?" ”

"The world is not peaceful, how can it be home?" Zhao Yun replied.

"Don't be so stubborn, you must know that Your Majesty's children have already started school. If you don't hurry up and work hard, you will miss the opportunity to be classmates with a few princes. Zhang Yan reminded.

Excluding him, Zhang Yan is already married, and his son Zhang Fang can already play soy sauce.

"That's it, isn't my little sister worthy of you?" Ma Chao unknowingly, he had returned here, and he didn't hear anything else, but he seemed to hear the two talking about his little sister.

"You ......" Zhao Yun was stunned when he heard this, and then looked ahead, Yang Angbu, who had been killed, had been defeated by Ma Chao unconsciously, and Yang Ang himself had been beheaded by Ma Chao.

The rest of the pursuit of the defeated army, it is estimated that Ma Chao found it boring, so he did not chase and came back directly to resume his life.
