"Your Majesty wait!" After getting off the city wall, Ren Baqian ran to the Chengling Mansion and stroked his spear, took another box out of the Chengling Mansion, and asked the guards to help him take it back to the vicinity of the city wall.

The Empress and Li Qianqiu were waiting there under the escort of a team of flying cavalry. Seeing Ren Baqian carrying a box behind him, they all guessed in their hearts what was in the box.

Ren Baqian asked the guard to open the box, revealing the rows of black round tubes placed inside.

Not big, but one palm is about one inch in diameter.

"Master Ren's Mansion, what is this?" Li Qianqiu asked curiously by picking up one and fiddling in his hand.

"Explosive!" Ren Baqian smiled.

This batch of explosives was obtained by him at the place where he bought a gun on Earth. It was divided into two layers: inside and outside. In the middle is 300 grams of TNT explosives, and outside is gunpowder, which is ignited with fire and detonated the TNT when the gunpowder explodes.

Originally, this thing was intended to be used for mining, and 300 were prepared, and this box was half of it. It turned out to be useless. This time I took it with me when I came out of Lancheng, and it was just right to use it at this time.

"Explosive?" Li Qianqiu was a little confused.

The empress knows a little about what the explosives are, but she doesn't know how to use them.

"You will know in a while." After Ren Baqian said that, everyone went up to the city wall again.

Ren Baqian squatted and tied the explosives to several long arrows, cut the lead behind the explosives, then looked up and said to Li Qianqiu: "Sir Li, I will ask you to find someone to shoot this under the opponent's catapult car in a while.

"I'll do it!" Li Qianqiu said unscrupulously.

In fact, the distance of 200 meters is almost the same for these ancient soldiers who grew up hunting in the mountains.

But he also wanted to see what Ren Baqian made.

Ren Baqian prepared a total of twenty-two chariots, and there were only twenty enemy catapults distributed around Liaocheng.

After he was ready, Ren Baqian handed the bow and arrow to Li Qianqiu. Before he could speak, the bone arrow turned into a white line and stabbed into a catapult car with a sharp sound of breaking through the air.

Ren Baqian:...

Li Qianqiu looked expectant and asked more than ten seconds later: "Why didn't you react?"

"There hasn't been lit yet..." Ren Baqian said speechlessly.

"Forgot, forgot!" Li Qianqiu laughed, and after laughing, he pinched a bone arrow and put it on the bow again.

Ren Baqian asked someone to take the ignition of the wooden strips to ignite the lead and quickly said, "Okay, let it go!"

The lead is still ten centimeters long, so it should be fine if it takes more than ten seconds, but he is afraid that something will be wrong with the lead. If it is a gunman, he will be in great trouble then.

As he finished speaking, Li Qianqiu's fingers were released, and the bone arrow once again crossed a distance of two hundred meters and was directly nailed to the catapult cart with a sharp sound of breaking through the air.

Then Li Qianqiu threw his gaze at Ren Baqian.

"Wait!" Ren Baqian looked at that direction with a telescope, and at this time he couldn't see clearly whether the lead was still burning.

However, before waiting for a long time, a loud "boom" sound suddenly came from the Great Xia army. With the sudden light of fire coming out of nowhere, the catapult instantly turned into pieces and flew around everywhere, hitting the iron shield in front of the military formation and making a collision sound.

The several soldiers loading around the trench were directly blown away by the explosion airflow, and two of them were only some broken corpses falling everywhere.

"Boom!" Just as the Daxia army was shocked by this sudden change, the Daxia army formation exploded again. This time, the unlit explosive tube was blown into the Daxia army formation and exploded again. At least ten meters of soldiers around were blown away by this explosion, and soldiers within a radius of five meters were directly blown to pieces.

"Good thing!" Li Qianqiu saw this scene on the city wall and immediately exclaimed.

"This box saves some use and is specifically designed to deal with their siege equipment. Without siege equipment, they probably can't do anything other than besiege.

They need to consume food here, and the food they need to consume is not a decimal place." Ren Baqian reminded him that he was terrible to Li Qianqiu squander at will.

"With this thing, no matter how many people they come this time, they can only watch from below." Li Qianqiu laughed and patted Ren Baqian's shoulder.

Then he asked several guards to take these bone arrows and apply them according to the method just now.

After seeing the explosion in the Daxia army formation, these guards were careful and immediately shot the bone arrows out as soon as they caught fire, for fear of blowing them into their hands.

Every one or two minutes, you can see a ball of fire bursting out in front of the Daxia Army formation and the sound of blasting explosions.

But in a moment, the six trenchers in the east of Lancheng turned into a pile of broken wood, and then a few explosions came from the north of the city in the distance, and then the east of the city.

In a moment, the trenchers of the Daxia Army turned into broken wood, and hundreds of soldiers who were killed by explosives or injured by broken wood.

"Let me take a look at this thing and keep it well. If there is any problem, you will ask me." Li Qianqiu said sternly to the guard behind him.

"Don't worry, Protector."

"Don't see open fire, don't bump, be careful to store it. Put it in a cool and humid place, remember to not touch the fire." Ren Baqianqin told everyone on earth that everyone knows the danger of this thing and cannot see the fire, but Da Yaoren always makes him feel a little worried.

If these things explode, probably one-quarter of Liao Cheng will be scrapped.

"Don't worry, sir." The guard behind him bowed.

The catapult was blown up, and Daxia would probably not have any other attacks today. Li Qianqiu continued to stay on the city wall to inspect, and Ren Baqian followed the empress back to the city's palace.

"Your Majesty is a little thin." Ren Baqian was talking nonsense with his eyes open on the way back. The empress is not an ordinary person, so her body naturally will not become fat and thinner as she eats more and less.

The empress was very helpful and glanced at him gently.

The guards behind looked at the sky one by one, pretending to hear nothing.

...

In the north of Liaocheng, a big tent in the camp behind tens of thousands of troops, a general with a fifty-bearded hair was standing in front of the desk and looking at the map above, with his fingers gesturing on it from time to time.

"General!" A middle-aged scribe came in from outside the tent and bowed.

The tent is the general who commanded the 700,000 army this time, the champion general, Wu Shenghou Jinling.

His reputation among the people of Daxia is far inferior to that of the Red Martial Arts in Dayao, because Daxia has not made any progress in the south for 70 years. In fact, he has a very high reputation in the court and can be said to be among the top three in the army.

In just a few decades, he could get a glimpse of the status of Wu Shenghou from a civilian to a third-rank general.

He has been stationed in the border for more than 20 years and has been preparing for more than 20 years. Even in his dream, he is thinking about how to attack Dayao. Now he can finally achieve his life's wish, and the battle situation is still in line with his expectations. Next, it depends on which side is better.

"How is that Lu Pinghai's injury now?" Wu Shenghou asked without raising his head.

"General, Lu Pinghai's injury has recovered for half of it, and it will definitely be fine in another month." The scholar bowed.

"It's still time." Wu Shenghou said softly.

"She still disagreed when Li Yuanzhu wrote to her." The scholar said again.

"As expected." Wu Shenghou was not surprised.

"Have Lu Zijian found it?"

"There is no news yet." The scribe continued. Lu Zijian, the second most famous person in the world, has always been unpredictable.

As for Lin Xian, the world's number one, there has been no trace for several years. Many people suspect that he is no longer alive or has broken through the legendary boundary.

"Do you think Qi Zixiao will leave Liaocheng?" Wu Shenghou asked casually.

"Not! If she left Liaocheng, she would have thrown down tens of thousands of soldiers and civilians in Liaocheng. Qi Zixiao would never have done such a thing. Unless she is at the moment of life and death, she will never be able to leave as she drags her like this now." The scribe said decisively.

Wu Shenghou nodded, just as he thought.

By the time she wanted to leave, it was probably too late.

Wu Shenghou moved his finger from one point on the map to another point, and finally pressed his finger on one of the points, where his target was.

It is not only a must-pass place for Lancheng and the Northern Protectorate, but also a must-pass place for the Northeast Protectorate to return to the rescue.

As long as you occupy this place, even if Qi Zixiao can escape back, he will throw away a large area of ​​fertile soil in the north...

"Is there any news on Yun Country?"

"They are still quarreling in the court." The scribe replied softly.

"Did they forget that they almost destroyed the country by those barbarians?" Wu Shenghou sneered and contempt. "Those guys full of merchant flavor..."

"Even without them, with the general's preparation for so long, it is not impossible to take down Da Yao." The scribe immediately continued. "The walls of Lancheng City are only six meters thick, and these catapults can break Liaocheng."

You should know that the walls of the Iron Cable Pass, Shuncheng and Ziyue City in the north are all twenty meters thick, and the Iron Cable Pass is even thirty meters. The walls of the Lancheng City are only six meters thick. As long as the trencher smashes a few more rounds, it can break out the gap.

"You can't even break it!" Wu Shenghou said lightly.

In places like the city, the powerful personal strength of the ancient tribe can be exerted. He would rather waste the ancient tribes to death near the city wall than let the soldiers enter the city to fight with the ancient tribe. Those ancient tribe civilians would probably cause them a considerable casualties.

Not to mention there are flying riders inside.

However, if the city wall is really smashed open, the developed thunder cannons will come in handy.

Thinking of another shell called Wanhua Bullet in his hand, Wu Shenghou felt that the court should really give the craftsmen a heavy reward.

Just as the two were chatting here, they heard a few loud noises from a distance that were different from the huge rocks hitting the city wall.

"Which bastard used the thunder cannon?" This explosion immediately reminded Wu Shenghou of the Vulcan cannons stored in the army and those things called thunder fire powder.

Then Wu Shenghou rejected this idea. He did not give an order, who dared to use the thunder cannon?

As soon as I walked out of the tent, I heard another loud noise in front of the formation.

"boom!"

Wu Shenghou frowned. What was going on? This was clearly the sound of the thunder cannon fire, but it was still so loud when it came here, and the sound was much louder.

Before he could figure it out, there were another loud bang in front of him.

"Come on, let's see what's going on." Wu Shenghou said in a deep voice.

After a quarter of an hour, a general wearing iron armor came back and knelt on one knee and said, "General, I don't know why, a fireball suddenly exploded out of thin air from the trench. It was very powerful, and the trench was completely destroyed."

Another quarter of an hour later, someone rushed to report it in both directions, and the catapults in both directions were also destroyed.
Chapter completed!
