Among them, one bow with three arrows is more than seven feet long. It can penetrate shields, gold and iron armor and other protective objects. It is powerful and most suitable for long-range killing.

The length of the stepping arrow is more than seven feet. It can be shot into the city wall to give full play to the effect of the ladder and help soldiers to attack the city.

The length of Hanya arrow is a little short, but it can shoot dozens of arrow feathers in a special iron basket. Because of its unique scattering effect, it can carry out a range of damage, making people nowhere to hide.

……

Xia Jin simply told Xiao Yiyuan about the function and power of the three bow crossbow

"I'd like to draw drawings and make three bow crossbows and one bow and three arrows now, and you can find more people who are involved in carpentry to help me make them, OK?"

Lu Qing is not in Yongzhou City at this time, otherwise, he who knows all kinds of secret devices will be her best helper.

"So good! If we can successfully kill the enemy's important generals, they will lose their morale and be of great benefit to our military aircraft! "

Knowing that Xia Jin is not a boaster, Xiao Yiyuan immediately calls Luo Ming and Luo Han, who are arranged by him to guard the south gate, and asks them to help Xia Jin make three bows and bed crossbows. He obeys his orders and can dispatch soldiers at will.

After the arrangement, he gave Xia Jin a signal tube, in case of uncontrollable factors, she can smoothly ask for help.

……

As the name suggests, the three big bows, the front, the main and the back, are combined in two positive and one negative ways and installed on a base called bed.

When the utility model is in use, the winch at the tail is rotated to drive the traction rope to pull the traction hook, the three big bows connected by the pulley are pulled apart, and then the used arrow is installed, so that a slightly greater force can knock the trigger on the machine bracket to shoot the arrow.

Its range and lethality are the best in the cold weapon era!

It is not easy to use such a powerful weapon. Every time it is launched, it will take twenty or thirty people.

……

After telling Su LuoMing and Luo Han the basic principle of the three bow crossbow, Xia Jin discussed with them.

After that, the three rushed to Liuji carpenter's shop, the largest carpenter's shop in Yongzhou City.

When the shopkeeper Liu Cheng learns that Xia Jin wants to make a powerful weapon to deal with the enemy who is besieging Yongzhou City, she is duty bound to let her use anything in the shop at will, and can send the shop assistants at will.

In addition, he went to other carpenters' shops in person to persuade other shop owners to help Xia Jin with him.

The violence of Zhou Boyi's soldiers a few days ago still fresh in the memory of these shop owners. The feeling of panic has not yet dissipated from the bottom of my heart.

Now, if Yongzhou City is destroyed, we can't imagine what kind of disaster they will suffer.

These shopkeepers readily agreed to help, and called around.

So there is such a scene, Yongzhou City, anyone who can do some carpentry work, all heard the news to Liuji carpenter shop, do their best to help Xia Jin.

When hundreds of people come to help, it's hard to avoid a mixture of good and bad.

The second is the skill. What I'm afraid of is that I'll sneak in the spies and learn how to make it. On the contrary, I'll make the garrison and the people in the city suffer.

In order to avoid this situation, Xia Jin only told LuoMing, Luohan and Liu Cheng how to make the crossbow.

Later, Liu Cheng was responsible for grouping the carpenters.

After Liu Cheng left, Xia Jin devoted herself to the drawing, while Luo Ming and Luo Han were waiting beside her.

No matter what happens, they must be protected by Xia Jin.

……

After drawing the overall picture, we also draw the detailed drawings of the parts, and an hour passes quickly and slowly.

Xia Jin is glad that she has an excellent memory. Otherwise, just because her brother had been wandering in front of her with drawings, she would never have written down so much about the detailed data of various parts, as well as the method of installation and use, let alone being useful today.

After the drawings were finished, she handed them to Liu Cheng and Luo Ming, who went to distribute them to the carpenters who had already divided into groups and began to make them.

As the intense production process begins, Xia Jin is responsible for the inspection, guidance and assembly, while Luo Han still follows her for safety.

Luo Ming and Liu Chengze are responsible for the scheduling and selection of materials.

……

Unknowingly, the sky gradually dimmed down.

After two failures, Xia Jin, with the help of Liu Cheng, a skilled craftsman, finally assembled the first three bow crossbow in a separate room.

"Luo Han, go to inform Xiao Yi... Cough... King Yi, and say that the first three bow crossbow has been made successfully."

Xia Jin is so excited that she almost breathes out the name of Xiao Yiyuan.

Although it was collected in time, the two words that had been exported were still heard by Luo Han.

It seems that the relationship between his royal master and Xia Jin is really quite different, as guard Lu said!

Will she be princess Yi?

……

Because Luo Ming is here, Luo Han doesn't worry about Xia Jin's safety. She answers the call and quickly heads for the south gate.

After about half a incense, he went back and came with three soldiers.

"Lord Xia, the king has an order to immediately transport the three bows and crossbows to the South Gate Tower."

"Good."

Xia Jin estimated in her heart that the width of the Yongzhou city wall was indeed enough to accommodate three bows and crossbows.

"Luo Ming, you stay here and work with manager Liu to supervise and guide the carpenters. I'll go to the city tower to have a look."

Although the production method is correct, Xia Jin still has to watch the successful launch of the first three arrows of this crossbow to be at ease.

"Don't worry, Mr. Xia. Manager Liu and I won't let you down."

"Yes, Mr. Xia, don't worry. I'll give it to LuoMing and me."

Luo Ming and Liu Cheng are reassuring Xia Jin.

Xia Jin nods, embraces six seven foot long bows and three arrows, and leaves with Luo Han for the south gate.

……

It took Luohan four people two quarters of an hour to get to the South Gate with three bows and crossbows.

From a distance, Xiao Yiyuan sees Xia Jin holding a bow and three arrows following Luo Han.

He quickly glanced at the enemy outside the city and entered a short rest state, and then used his lightness skill to fly towards Xia Jin.

Just a few breath, he will fall in front of Xia Jin, landing silent.

He ordered Luo Han to go to the city building first, and then he spoke to Xia Jin

"Tired? Give it to me

His voice and face were gentle.

Between the words, stretch out one's hand and then want to take Xia Jin hand even higher than her a bow three arrows.

Xia Jin because of his gentle and short Lengshen, reaction to come over, a bow three arrows has been he took over.

"Puff..."

Xia Jin couldn't help laughing, because she was worried about whether the power of three bows and crossbows was as good as she said.

"Why laugh?"

Xiao Yiyuan frowned slightly. He could not see his emotion on his cold face, but in his deep black eyes, he was full of tenderness and indulgence.
