"Zhang Shijie, be careful. Pen, Fun, Pavilion www.biquge.info" Yang Wen said in a low voice, after Zhou Meng's death, Zhang Shijie was his cronie.

Zhang Shijie nodded, and also said in a low voice: "My lord, you should also be careful." ”

After Zhang Shijie finished speaking, he waved his hand to Liu Daxiang, and the two of them continued to crawl towards the ancient castle with a big jar in their arms.

Although not long ago, due to Li Xiang's night attack on the giant artillery factory, the Tartars had strengthened their defense and vigilance, but after a few months, the Tartars have also relaxed a lot, especially the ancient castle, which is neither the first line of defense nor a key fortress, so the Tartars are naturally more relaxed.

Seeing that the two of them had come to the ancient castle, the Tartars in the castle did not find anything, it was the time of the third watch, it was the time when human beings were most sleepy, except for a few lazy laughter occasionally in the castle, the silence in the castle was as if time had stopped.

Yang Wen couldn't help but hold his breath, if the Tartars found out, with their archery skills, I am afraid that Zhang Shijie and Liu Daxiang would not be able to escape their fate.

I saw that Liu Da wanted to take out a small tool from his arms with the help of the faint Yuehua, Yang Wen recognized that it was the tool used by Tufuzi when he robbed the tomb, and the sound of this tool when digging the soil was very small, and it could not be heard at all if he was not careful.

Liu Daxiang made a gesture to Zhang Shijie, meaning to let Zhang Shijie help watch the wind, he used to do a lot of messy things when he mixed the rivers and lakes, since Li Xiang summed up the experience of the battle of Enzhou and the Sanduozhai assault battle, once said that for some not very strong city walls, if the soil bomb is planted well, the power of the explosion can completely break the city wall, but there is nothing that can be done about the relatively strong city wall.

The ancient castle really belongs to the forest wall that is not very strong, after all, it is an auxiliary fortress outside Jiang'an City, and naturally it will not be built as strong as Jiang'an City, but it can be held without siege vehicles and trebuchets attacking.

"Poof, poof, poof." Although the sound of Liu Da wanting to dig the soil was very small, it was still very eye-catching in this quiet night, but I don't know if it was the Tartars who ignored it or Liu Da thought that the two of them were super lucky, and after the two of them put the earth bomb, they didn't alarm any soldiers.

Liu Daxiang and Zhang Shijie slowly retreated and came to Yang Wen's side, Zhang Shijie breathed a sigh of relief and said, "My lord, the earth bomb has been placed, please give an order." ”

After all, Yang Wen had never seen the power of the earth bomb, and was a little worried: "Is it really okay?" ”

Zhang Shijie led the death squad to storm the Jinsha River defense line last time, and it was a storming of the ancient castle at that time, and he was naturally clear about the power of the earth bomb, and although Liu Daxiang had not seen it with his own eyes, whether it was Liang Wu who participated in the attack on Enzhou, or Li Ji, Lu Wu and others who followed the adults to attack Sanduozhai, they all appreciated the power of the earth bomb, and they were completely set up in accordance with the methods taught by the adults, and they had some confidence in their hearts: "My lord, please rest assured, if the earth bomb is not effective, I Liu Daxiang will be the first to kill it." ”

Yang Wen glared at him, and said in an urn voice: "You kid is now a member of the Shaoxi Mansion Army, if there are any three long and two short, I can't explain to Lord Zhang, my Jiang'an City's matter is not your turn to die, since this is the case, you let the brothers prepare." ”

Gan Zuxing has thick eyebrows and big eyes, similar to Yang Wen, presumably this is a group of people to gather like things, Gan Zuxing has followed Yang Wen for no less time than Zhou Meng, but this person can solve things by force and will never use brain power, so he can only stay at the level of commanders.

"My lord, please order, such a rabbit cub can't bear it for a long time." Gan Zuxing smiled, revealing a row of white teeth, which looked a little strange in the dark night.

Seeing Yang Wen nodded, Liu Daxiang blew the velvet in his hand, and soon a little spark appeared, and then ignited the fuse of the earth bomb.

The sound of "snort, snort, snort" continued to approach the ancient castle along the lead, Liu Daxiang hurriedly covered his ears with his hands, and Zhang Shijie, Yang Wen and others also did the same when they saw this.

Seeing this lead disappear into the dirt, Yang Wen's heart jumped up suddenly, a kind of tension that had never been before, so that Yang Wen didn't even dare to breathe loudly, this is completely different from the previous siege strategy, if this attack method is proved to be effective, then the siege and defense of the city in the future may be carried out in a completely new way.

Suddenly, just as Yang Wen was careful, there was a loud "bang", which instantly made Yang Wen lose his senses, and everywhere his eyes could see, he saw a flash of fire, and then a puff of smoke flew up.

I vaguely saw that the ancient city wall shook, but it did not fall down immediately.

"Holy shit, it's too faceless." Liu Daxiang reacted the fastest, and when he saw that the city wall had not collapsed, he rushed up as soon as possible.

After all, Yang Wen is a general in the army, and he has gone through a lot of things, and he has already reacted when he saw Liu Da wanting to rush up:

"Liu Da thought about the dog's day, this is Lao Tzu's business."

After Yang Wen finished speaking, he also rushed forward with the spear in his hand.

Although Zhang Shijie is more familiar with the power of the "soil bomb", this kind of reprocessed soil bomb is more powerful than before, and when he saw Yang Wen rushing up, he also reacted, and shouted in his mouth: "My lord, be careful." ”

Liu Daxiang is famous for running fast, and in a blink of an eye, he has come to the place of the explosion, he is angry, and the big foot girl is about to kick over, but he can't imagine that the city wall has been shattered by the explosion of the earth bomb and the skeleton has been scattered, where is Liu Daxiang's big foot still used?

"Boom", in the surprise of Zhang Shijie and Yang Wen, the city wall collapsed like this, if Liu Daxiang didn't react quickly, it is estimated that the collapsed city wall would have crushed him to death.

"Grandma, if you don't lose your temper, you still think that Lao Tzu is a bitch?" Liu Daxiang looked at the collapsed city wall with a smug face, and said proudly.

At this moment, Gan Zuxing has led the soldiers to come, these have been trapped in Jiang'an City for several years, and they have already developed a fiery temper, seeing the collapse of the city wall, it is not a swarm of swarms to rush up, Liu Daxiang is naturally willing to follow to mix up the merits.

With mental calculation or unintentionality, Yang Wen won the victory at the lowest cost.

On the same night, the ancient castle on the bank of the Jinsha River, Xingyue Fort, the Daimyo Fort, Zhaomin Fort, Zhonghe Fort and Pingshan Fort in the north of Jiang'an City, a total of six fortresses, were recovered by Yang Wen and others in one go, and Shi Tianxing's department had no time to react, and the defense line was forced to retreat ten miles back.

Easily wading across the Tsing Yi River, Zhang Yuanzhi couldn't help but worry, in the jungle, the person in the canyon set up an ambush, and the art of war was half the way to attack, could it be that person who easily let himself go?

If there is a sudden flood upstream, his retreat is cut off, although there is a sailor's response, but he can only pick up the soldiers, and the rest of the horses can only be killed or given to that person, which Zhang Yuanzhi has to consider.

You must know that the Mongols went out on an expedition, each person brought five war horses, although the distance is relatively close now, but in order to attack Shaoxi Mansion, Zhang Yuanzhi still let each person bring two horses, two thousand people count a full four thousand horses, even if the Mongolian Empire is not short of war horses, but if these four thousand war horses are in the hands of that person, I don't know what kind of chaos will happen.
