"This, what is this?"

Bai Yi's face was also a bit pale, and he looked at the scene in front of him rather ugly.

She couldn't figure out what it was that caused the ground to shake in an instant, causing the ground to crack in front of her.

"How do you think of the weapon that my husband got, the famous explosive? It's powerful, isn't it?"

Lu Chensheng looked at Bai Yi beside him with a somewhat showy look.

When Bai Yi heard this, Feng Mu couldn't help but look at the big pit in front of him, and then looked back at Lu Chensheng.

"You have something like this, why didn't you take it out earlier?"

"Take it out earlier? It's not time to go to war yet, so what are you going to use it for? It's more convenient to use it to dig mountains and dig rocks."

Lu Chensheng was a little strange, looked at Bai Yi and responded.

Bai Yi was slightly startled when asked, "Well, since there is such a thing, we will only need to use these in future wars, right?"

"That won't work. This explosive still has some limitations. When we face the charge of the Tatars, this alone will not be enough."

Lu Chensheng shook his head, wondering why the limitations of explosives were so great.

Just thinking about relying on explosives to defeat the opponent is a bit whimsical.

Close combat is essential.

Bai Yi thought about it and felt that what Lu Chensheng said was right.

She was also frightened by this explosive just now, and suddenly she felt that with such a thing, what kind of hand-to-hand tactics, tactics, and formations would be necessary in the future.

Anyway, when people come, why not just throw this thing away?

Qiong Yue was at the side. Due to Lu Chensheng's reminder just now, as a grand master, she quickly calmed down, but there was still a look of surprise in her eyes.

"Did your husband rely on this thing to bury those thousands of Tatars?"

Qiong Yue immediately thought of Lu Chensheng's previous achievements in the expedition.

When Bai Yi heard this, he couldn't help but turn his head and look over. He had heard before that Lu Chensheng had unpredictable abilities.

Take a look now.

Bai Yi turned around and looked at the big pit that appeared on the ground. It was really unpredictable!

"Yeah, I was lucky at that time. There was such a cave. After it collapsed, I buried them all. Otherwise, it would be difficult to kill them all just with explosives, let alone the effort.

Points of casualties.”

Lu Chensheng's explosives were originally intended to surprise the opponent.

When the opponent panics, the situation on the battlefield will change.

But that cave provided a better opportunity.

As Lu Chensheng spoke, he arranged for people to continue digging holes and bury explosives.

The water column on the side is still spraying continuously, seemingly endlessly.

A moment later, there was another roar, and the pit on the ground became much deeper.

The soldiers helped dig and clear away some soil.

"Shopkeeper, we have no more explosives."

Gu Zhifang exploded once, and then walked up to Lu Chensheng with an embarrassed look on his face.

This thing was originally used to blow up boulders and so on, so I didn't prepare much.

Nowadays, large-scale use has directly led to the bottoming out. It should be said that it is completely gone.

Lu Chensheng's face froze slightly when he heard this. Now he wants to process it urgently, but it is impossible.

There is simply no such time.

"Put the water in."

Lu Chensheng sighed, now he had no choice but to do this.

When everyone heard this, they started working immediately.

A small opening was dug from the side, and immediately water slowly flowed in. However, within a short time, the gap became wider and wider.

"Now start digging a canal leading to the city."

Lu Chensheng gave another order from the side. Sooner or later, this small lake will be filled up. What can be done now is to dig a canal as soon as possible.

Otherwise, the water would fill up the valley and then flood Xinghan City.

Everyone immediately started to move, and Lu Chensheng started to work at this time.

Digging a canal is not that simple, especially when it is quite far away from the city, it is even more difficult.

By the time Lu Chensheng and others held up torches and worked until midnight, water had already filled the surrounding area.

However, with the help of water, the canal became easier to dig.

"How is the situation in the city? Is it flooded?"

Liu Wensheng hurried over. He didn't close his eyes even at this time, he was still running around.

"Already, water has flowed into the city. The houses in low-lying areas have been flooded, but the people have moved away. There is no serious problem."

Liu Wensheng heard this and immediately responded.

Lu Chensheng breathed a sigh of relief and said, "That's good. How is the excavation of the canals in the city going?"

"This is not easy to dig."

Liu Wensheng burst into tears when he heard this. His eyes were now bloodshot and his face looked a little haggard. "The soil here is relatively dry and hard, and the difficulty of excavation has increased a lot."

"Isn't the city going to be flooded?"

Lu Chensheng became anxious after hearing this.

There are several places in the city now that are extremely important and cannot be flooded at will.

Liu Wensheng waved his hand after hearing this, "Don't worry, do you still remember the well water in the city? I directly had people dig a channel and introduce the water into the well water. The well water did not overflow, and the situation was temporarily relieved.

Some."

Lu Chensheng was startled when he heard this, and then glanced at Liu Wensheng.

He was a little anxious before, but he forgot that he could actually use a well to drain water.

Basically, it is impossible for the water in the well to overflow.

"Okay, your mind has become a lot smarter recently!"

Lu Chensheng's face flashed with joy, he patted Liu Wensheng on the shoulder and said.

Liu Wensheng did give him a surprise this time.

"Didn't you always say before that you wanted me to go and study with those students? Do you really think I didn't go?"

Although Liu Wensheng felt a little embarrassed, he still found Erhu and others and learned a lot of knowledge.

For example, underground rivers and some knowledge that the earth is round.

"Yes, Not Bad!"

Lu Chensheng's face was full of joy, and he began to dig the canal desperately.

After being busy until white fish belly appeared on the horizon, Lu Chensheng was persuaded by everyone to go back and take a rest.

Last night, people were divided into two groups. Lu Chensheng checked the time and asked them to go back to rest, and replaced those who had already rested to continue.

Although Lu Chensheng has been practicing martial arts and has become much stronger, a night of hard work still makes Lu Chensheng feel a little unstoppable.

Ignoring cleaning, Lu Chensheng found a room and lay down directly to sleep.
