After hearing this, Wang Yu changed his view of him and turned out to be a filial and responsible man.

Wang Yu took off the bag on his waist and handed it over: "This is for you. Thank you for telling me this. However, I hope that no one else will know about what you told me except you and me."

"Don't worry, I will keep it secret."

The soldier took the bag and touched it secretly. It was not copper coins, but other valuables.

Thinking of this, he was secretly happy, stuffed the pouch into his arms, and stepped aside.

On the surface, Wang Yu was eating calmly, but in fact, his heart was already filled with turbulent waves that kept rolling.

Yesterday, she was wandering around the camp and overheard someone talking about the newly made three-bow crossbow in a corner. One person said that when he accompanied the imperial army to conquer Dou Jiande, he had seen a lighter three-bow crossbow than this one.

So Wang Yu called the man aside and asked a few questions.

The three-bow bed crossbow she made is something that only appeared in later generations. Is there actually a bed crossbow that is more advanced than this?

This craftsman is either a genius, or someone from later generations traveled through time.

There is actually a weapon called "flying fish bomb" now?

Although the soldier only used the sentence "can kill people" to describe the "flying fish bomb", it was enough to shock her.

Obviously, this Exocet bomb is not an Exocet missile, but it must be an artillery shell.

Of course, gunpowder already existed in the Tang Dynasty, but its application in military applications was only in the late Tang Dynasty, which was still more than two hundred years ago.

The person who can make these weapons is definitely from modern times, and he is a person who is very good in science.

Wang Yu stopped her chopsticks. She was very excited. She was excited that there were similar people in this era. Finally, she was not alone.

Of course, such a powerful person should be on the same side as her.

If they are not on the same side, then pull him over.

"I'm full." Wang Yu stood up and left the table.

The soldier immediately stepped forward to clean up the food table. After finishing, he took the food box and left the tent.

He deliberately turned a corner and walked to a secluded place. He took out the bag from his arms and looked at it. It was gold, and he felt ecstatic in his heart.

Wang Yu was sitting behind the desk, looking at the book with great concentration, and lowered his voice: "You have been following me for so long, you should know what to say and what not to say, right?"

Daquan's heart trembled: "I understand, I didn't hear anything just now."

Wang Yu was secretly satisfied and said calmly: "Okay, you go and eat."

Daquan quietly exited the tent and warmly greeted the third and fourth left: "Let's go eat together."

The third person on the left remained unmoved and said to the fourth person on the left: "You go to eat first, I will stay here."

So Zuo Si and Daquan left.

Wang Yu stared at the two pieces of paper on the desk and fell into deep thought.

The three-bow bed crossbow in the Changle King's Army stacks the crossbows one above the other, so it is smaller than her bed crossbow, and only ten people are needed to activate it, which saves a lot of manpower.

I don’t know how this thing was modified?

Alas, she thought about it all day and night, but still couldn't find a breakthrough.

but.......

Her eyes moved to another piece of paper. Although she couldn't study the three-bow bed crossbow for the time being, she could still give this five-arrow repeating crossbow, which was lighter than the Zhuge Liannu, a try.

Thinking of this, Wang Yu immediately laid out a piece of white paper and started drawing.

That night, the candles in Wang Yu's tent burned very late...

--------

The next day, Mao hour.

Li Jing led 20,000 elite troops to attack and quietly launched an attack on Hedong City in the darkness.

The Sui army soon discovered that the rebels were attacking the city with ladders, and immediately took measures to destroy the ladders.

Seeing that the strategy of quietly climbing the city failed, Li Jing ordered the three-bow crossbow to be activated.

"Bang bang bang——"

The Sui soldiers on the city wall panicked and shouted: "General, their crossbows are coming to kill you."

Needless to say to the soldiers, Qu Tutong and Yao Junsu had already seen that the moment twelve thick stilt arrows were inserted into the city wall at the same time, they faintly felt the city wall trembling under their feet.

Maybe it was an illusion, but most of the soldiers had expressions of horror in their eyes.

"Hurry up and throw fire oil and stones."

As long as the city wall and the arrow shafts are covered with oil, they will not be able to stand firm and climb the city wall.

When the arrows formed a new ladder, the Xuanjia army in the front line immediately rushed forward. As soon as they hit the arrow shafts wrapped in kerosene, the Xuanjia army's hands and feet slipped and fell down.

There were also stones and arrows falling from the sky. Many Xuanjia troops were hit and had to retreat.

Li Jing was worried, so he summoned a thousand vanguard troops, took off his boots in public, took out his dagger, and then used the dagger to make several cuts on the soles of the boots.

He controlled the strength very well, neither deep nor shallow, and made a mark at a certain distance. After a while, the sole of the boot became uneven.

"Look, now you can follow my method and take care of your boots."

Everyone soon understood that the uneven soles of the boots would not slip when stepping on oiled arrow shafts.

By the time everyone had finished handling the boots, Li Jing had already asked someone to come over with a coarse cloth, "Wrap their hands with the coarse cloth. Don't wrap it too tightly, so as not to affect their movements, but don't wrap it too loosely."

After everything was dealt with, Li Jing ordered the Xuanjia Army: "Go to the city and use the Zhuge Liannu to restrain the opponent's archers."

More than a hundred Xuanjia soldiers immediately ran to the city, within the range of Zhuge's crossbows, and shot at the archers on the city wall.

Ordinary bows and arrows are not as good as Zhuge's continuous crossbows, and the Sui army cannot shoot at the Xuanjia army. After a few shots, all the archers at the wall hole fell down.

"Siege the city."

A thousand vanguard troops, fully armed, rushed towards the city wall.

There were no more archer attacks, and there were still stone-throwing attacks, but with the restraint of Zhuge Liannu, the attack was not too fierce.

The vanguard troops were a little happy. When they climbed steadily onto the stilts, the joy in their hearts became even stronger.

The deputy commander was really smart and easily defeated the enemy's fire oil.

Due to the fierce shooting of Zhuge Liannu, Qu Tutong and Yao Jun never dared to move too far forward. Now they heard a little silence under the city and couldn't help but urge the soldiers: "Go and see what's going on under the city?"

The soldier cowered and hid most of his body behind the city wall, looking down from the hole in the wall.

"Hey~"

The soldier hurriedly retracted his head, and a defender behind him suddenly fell down with an iron arrow stuck in his chest.

so close!

The soldier patted his chest with lingering fear.

"How's it going?" Yao Junsu asked.

The soldier hurriedly replied: "They are climbing the city and are already halfway there."

Everyone was shocked.

Yao Junsu immediately ordered: "Throw stones quickly and archers will make up for them."

The soldiers looked at the corpses on the wall and on the ground, but no one moved.

They don't want to die.

Qu Tutong was furious: "Whoever retreats will be killed without mercy."

As soon as he said this, the soldiers behind Qu Tutong showed their swords and approached the soldiers step by step.

At the same time, there were also personal soldiers of Yao Junsu.

Forced by the military prowess of the two men, the soldiers mustered up the courage to throw stones and shoot...

Within a moment, another layer of corpses was added to the city wall.
Chapter completed!
