Although the Xuanjia Army was within range, they used their shields to form an extremely hard barrier to withstand the rain of arrows.

Qu Tu was in a hurry, and shouted: "Throwing stones, rolling logs, pouring fire oil, no matter what method is used, you must not let them get close to the city wall." ”

As soon as he thought of a possibility, Qu Tutong felt powerless.

He couldn't let the other party succeed.

Stones and rolling logs fell from the sky and were kicked away by the Xuanjia Army.

The oil was splashed down and was caught by the Xuanjia Army.

By the time the rocket was fired, the Xuanjia had already dug a deep trench under the rammed earth layer, made many holes in the exposed rammed earth layer, and then built a thin wall on top of the collapsed city wall.

And between this thin wall and the rammed earth layer inside, there is a hollow layer more than a foot wide, which happens to be flush with the original outer wall, and from the head of the city, this thin wall is not visible.

"Withdraw."

The Xuanjia army withdrew from the city walls, which had been rekindled by fire.

However, the fire on the walls was quickly extinguished.

Qu Tutong looked at the empty city, a little puzzled, "What did they do just now?" ”

Since there were dozens of shields spliced together just now to block their view, they couldn't see what was happening under the shields at all.

Out of an instinctive sense of crisis, Qu Tutong felt that there was something wrong with the city wall.

No matter what the other party wanted to do, as long as he blocked that wall, they couldn't do anything.

Thinking of this, Qu Tutong pointed to the ruined city wall and instructed the soldiers: "Remember this location, throw stones down, and pile up a wall."

"The archers are in position, and no one can be allowed to approach this wall."

It didn't take long for a young general to run over, "General, we have run out of stones, and the reserves in the city have also been used up. ”

Qu Tutong was a little irritable: "Then go and demolish the house, prepare more stones for backup, as well as bows and arrows, the more the better." ”

"That'...... How to block the damaged city wall? The young general hesitated and asked.

Qu Tutong couldn't help but shouted: "Then find something else to throw down, no matter if it is smashed or not, as long as it can block that wall, throw it down." ”

The youngster hurried to find something.

---------

Li Jing looked at the thin wall that had been re-erected, and his mood was very complicated.

The soldiers of the Xuanjia Army are still struggling.

Some of the warriors used shields to protect their bodies and removed stones, logs, and other debris outside the city walls; Some of the warriors dug a small ravine from under the thin wall that stretched to where they were standing, that is, outside the range of the enemy's bows and arrows.

"Add water."

Hearing Wang Yu's order, Wang Kangda immediately picked up a bucket of water and slowly poured it into the ditch.

The water is clear, and along the ravine, trickle into the thin walls.

Seeing that the water in the ravine was running out, Wang Kangda slowly poured another bucket of water.

This is repeated until the ravine is full of water and no longer dries up.

Wang Yu told Wang Kangda: "Look at it, once the water level drops, you will immediately add water." ”

"Yes." Wang Kangda responded, his eyes fixed on the ravine.

Li Jing finally understood what Wang Yu wanted to do, and he had to admire, "Xiao Yu'er, do you want to use water to break down the rammed earth layer in the middle, and then use the old method to concoct it to destroy the stone layer inside?" ”

Wang Yu smiled and nodded: "The superficial plan is like this?" ”

"Surface plan?" Li Jing was a little confused: "What is the actual plan?" ”

"Keep it a secret."

Wang Yu's expression was full of mystery, and she turned to the Xuanjia Army soldiers and said, "You have done well today, and everyone has it, and you will be rewarded with a new weapon." ”

The crowd cheered.

Daquan leaned over and looked at Wang Yu with fiery eyes: "What about me?" Do I have any? I also helped. ”

Hearing this, Wang Kangda and Yang Mao also walked over, looking at Wang Yu expectantly, if Daquan has it, then they must also have it.

After all, they do more than Daquan.

Wang Yu slowly moved his gaze to Li Jing, but said to Daquan: "Then it depends on whether the deputy marshal agrees." ”

Daquan, Wang Kangda, and Yang Mao immediately set their eyes on Li Jing.

Li Jing glanced at Wang Yu, the five-arrow repeater was originally developed by her, not to mention that she had already told the craftsman that the crossbow made first was close to her soldiers, what else could he say?

can only maintain her face, after all, she watched such a wonderful play today.

"Ahem......" Li Jing cleared his throat and said slowly, "In view of your brave actions today, I will reward you." ”

The three of them were overjoyed and thanked each other.

Turning around, everyone gathered together again, "Alas, what is this new weapon?" ”

Daquan said excitedly: "I know, I tried it last night." ”

Everyone hurriedly urged: "What kind of weapon?" What does it look like? Say it, say it......"

Li Jing looked at their excited appearance, and couldn't help but be infected by it, and his mood was a little lighter.

He sat down after the table he had just set up and asked Wang Yu: "Xiao Yu'er, I have something I don't know, and I want to ask you." ”

Hearing this, Wang Yu knew what he wanted to ask, and sat down opposite him with a smile: "Deputy marshal, please say, I must know everything, and I will say everything." ”

"How did you come up with this way of destroying the walls? Why does the outer layer collapse after burning? ”

Wang Yu took a sip of the teacup and said slowly: "I saw it from a book, but the book has been lost, and I don't know the title of the book." ”

Li Jing: "......."

She blocked all the questions behind him, and she couldn't find the book even if she wanted to.

"Actually, as I said before, if the outer layer of the wall was made of masonry, my method today would not work.

"But the walls of Hedong City happen to be the outer layer of stone, which gives me an opportunity."

Li Jing was puzzled: "How do you say this?" ”

Wang Yu took another sip of tea: "Under the calcination of the stone at high temperature, it will suddenly encounter cold water, and it will explode because of the huge temperature difference. At this time, with a light knock, the stone shatters. ”

"I see!" Li Jing suddenly realized, and his heart changed his opinion of Wang Yu again.

Sure enough, if you want to be smart, you should still read more books.

After this battle, after his wife and children arrived in Chang'an, he must buy more books for his sons to read.

Thinking of the repeater he saw last night, Li Jing suddenly had a bold guess: "I heard that the craftsman said that the five-arrow repeater was developed by you, could it be ..... Then the Zhuge crossbow was also developed by you? ”

If that's the case, it's really a gifted little prodigy.

Wang Yu curled his lips and smiled: "I just provided the construction drawing, and the specific finished product is still the credit of the craftsmen, I don't dare to take credit." ”

It's already great to be able to draw a structural drawing, but you don't dare to take credit?

At a young age, he doesn't fight for fame, and he is so modest, which is really very human.

Li Jing got up and suddenly looked at Wang Yu: "Wang Xiaoniang is talented, Li was sluggish in the past. ”

Wang Yu was taken aback by his actions, and hurriedly went to help: "The deputy marshal is serious, Wang doesn't dare to be it." ”

Li Jing took advantage of the situation, and his eyes became kind: "In the past, in Jinyang, you always called me Uncle Li. ”

"Isn't this in the military, there is a clear distinction between public and private." Wang Yu sat down with a smile: "What's more, I have made a military order now, and you are my immediate boss."

"If I call Uncle Li, if the mission fails, how can you be embarrassed to punish me?"
