Therefore, even if most of the main forces of the Northern Zhou Dynasty in Xiangyang have already gone north, the rest of them should not be underestimated, otherwise Yuwen Yong would not really be so big that he could threaten the Jingxiang land of the Central Plains in this north, leaving only so few soldiers and horses.

Yu Wenyong, the young male lord who unified the north, would never make such a mistake, and Yang Jian, Wei Xiaokuan, Wei Chi Hui and others around Yu Wenyong would naturally not allow him to make such a mistake.

Xiao Shilian knew very well what kind of opponent he would face, and Li Xinchen, who was walking in front of him, kept frowning, obviously he understood better than Xiao Shilian, and was more worried.

"Let's go, we have no choice but to defend this Zhangshan County now." Li Xinchen said in a low voice, took the hat and walked straight into the wind and rain. Far from being smaller, the rain outside was even greater, and the raindrops hit the eaves and Li Xinchen's hat.

The rain smashed in front of the steps, splashing countless droplets of water and mist, engulfing Li Xinchen's figure in an instant.

Xiao Shilian didn't think about it, and walked straight to follow Li Xinchen.

As Li Xinchen said, when they decided to go north from Ji Nan City, there was no way out. Now there is no point in hesitating and fearing sincerely.

Heavy rain is still falling, and in the summer, the rain in Jiangnan can come at any time, which is confusing.

And maybe because of the recent heavy rains, or maybe because this era is in the Xiaoice period after all, so the rain is very cold, even comparable to spring and autumn, sometimes the rain pours into the clothes and boots, and the wind blows people can't help but shiver.

However, this did not stop the soldiers from working, and from time to time there were neat trumpets in the sound of wind and rain, and the moat, which had been dried up into a trench, gradually advanced towards the water in the sound of wind and rain and the sound of trumpets.

Along both sides of the moat, the soldiers were digging covered in mud and rain, and they not only needed to reconnect the moat with the water, but also needed to widen the moat, especially the moat around the city gate, after all, in the case of a moat, filling the moat near the city gate and attacking the city gate directly has always been the best choice.

"Join the army, battle lord, why did you come here?" A general was not wearing armor at all, and was carrying a shovel shirtless, and he was very surprised to see the people who appeared in the wind and rain.

"Lao Tzu is not made of mud, why can't he appear here?" Xiao Shilian scolded with a smile, the rain blocked his vision, making Xiao Shilian unable to see the situation further away, "What's going on over there?" ”

The general frowned and said: "This moat is really not artificially dried up, the soil by the river is relatively soft, and it is easy to block it over the years, and now it is raining again, and it is basically mud over there, which is difficult to dig, but it is easier to widen the river on our side." ”

"Let's go, go over and have a look." Li Xinchen picked up a shovel and walked straight along the moat.

If the entire moat wants to have water, the most important thing is still in the source of the water, the water cannot be dug on the other side, and no matter how wide this side is, it is only a trench after all.

"Battle master, join the army, the wind and rain are too big, and no one knows when the barbarians will be killed, so you should hurry up" The general hurriedly wanted to stop Xiao Shilian.

Xiao Shilian stretched out his hand to block him, and said with a smile: "What's there to worry about, even if the barbarians really come, are the guys in your hands all eating dry food, not to mention how important this moat is, you also know in your heart, as the commanders of the first army, there is no reason to sit idly by, you kid will hurry up and do your own!" ”

The general nodded solemnly, and after Xiao Shilian left, he turned around and found that the rest of the soldiers were looking at this side curiously, and suddenly glared at him and shouted: "You guys, whatever you see, you all work for Lao Tzu, if anyone is slow, Lao Tzu will kick you into the ditch!" ”

"Lord!" Seeing Li Xinchen digging with a shovel, Chen Zhishen hurriedly ran over.

And Li Xinchen didn't raise his head, but raised his voice: "What's wrong?!" ”

"Lord, why are you here, it's too dangerous here, so I'll send someone to send you back!" Chen Zhishen suddenly said anxiously. Although I haven't seen the Northern Zhou people yet, after all, this is also outside the city, and there will be any accidents if you don't keep it.

And Li Xinchen and Xiao Shilian are undoubtedly the souls of the army, if something goes wrong with the two of them, then this city really doesn't have to be defended.

"What nonsense, hurry up and work for Lao Tzu!" Li Xinchen raised his head and glared at Chen Zhishen, "Lao Tzu gave you a hundred brothers, but you haven't dug through this thirty-zhang long place until now, what are you eating?!" If this moat can't be dug through, how can this city be defended?! ”

Chen Zhishen suddenly didn't dare to answer, and hurriedly glanced at several soldiers around him and asked them to follow Li Xinchen.

And Xiao Shilian also ran over covered in mud: "Shizhong, it can't go on like this, the soil here is too soft, we don't know how much water is and how much is mud when we go down this shovel, and the place just dug down will soon be filled with mud." ”

The rain flowed down the hat, Li Xinchen wiped his face, took off the hat directly, and said loudly: "Chen Zhishen! ”

Chen Zhishen hurriedly ran over: "The end will be!" ”

"Go, there are still a lot of discarded bamboo rafts and boats on the wharf outside the city, all of which have been moved over and thrown down along both sides of the river, especially bamboo rafts. Then fix these together, preferably without gaps, and take all the sandbags we used to defend the city, against both sides of the river! Li Xinchen said loudly.

"No!" Chen Zhishen hurriedly agreed, but immediately replied with a bitter face, "But the lord, we don't have enough manpower, and if we want to fix this section of the river, I'm afraid it will take a lot of effort." ”

Li Xinchen frowned, rolled up his sleeves: "Do you see this river, spread the bamboo raft flat on the river, and then put the things to be transported on the bamboo raft, and the person pulls the bamboo raft away!" ”

"Will this work?" Not only Chen Zhishen, but Xiao Shilian also looked at it in surprise.

Li Xinchen said in a deep voice: "Try it." ”

The bottom of the river is actually already mud, if you simply step on it, it is easy to fall into it, although it will not swallow people, but it will inevitably be difficult to walk, and spread on the river with bamboo rows, it will increase the force area, and then reduce the force per unit area. Naturally, the sagging of the mud will be further reduced, which will speed up the movement.

Of course, these superficial physics knowledge are naturally still fantastical for people in this era, so Li Xinchen doesn't know how to explain it, and the only thing he can do is to give it a try.

And when Xiao Shilian looked suspiciously at Chen Zhishen and the others who were dragging the bamboo row, a scout ran over quickly: "Qi Qi joined the army, the battle master, and found a team of cavalry five miles north of the city!" ”
