Three Kingdoms: The rebellious son of the Cao family married the queen at the beginning

"Your Majesty, I have come back to reply to your orders. Liu Biao's army in Runan County has been completely wiped out. Our army exchanged prisoners and got 400 million shi of food and grass. General Zhang sent back 200 million shi."

Cao Shuo nodded, and then ordered: "Xu Chu, I now appoint you as Jing Zhaoyin, responsible for the security around the capital."

Zhang Liao stayed in Runan County, so Henan Yin's defense needs someone to take over, and that must be the person he trusts most, and Xu Chu is definitely the most suitable.

Xu Chu said excitedly, "Thank you, Your Majesty, for your promotion!"

Cao Shuo said meaningfully: "Zhongkang, when you have nothing to do, ask a few advisers for advice on the art of war, and read more ancient books and allusions."

"What the king said is true!"

In order to speed up the construction of Luoyang City, Cao Shuo issued a military order to all the prefectures and counties of Wei State, and only defended but did not attack within two months.

Cao Shuo spends all his free time in the military computer room except for leisure and entertainment with his concubine every day.

He wanted Ma Jun to research the Liannu as soon as possible. As long as he could successfully research it, his infantry would be upgraded several steps.

Facing the cavalry alone, the infantry also has a certain ability to protect itself.

"Your Majesty, Your Majesty, I have researched it, I have researched it!"

Under the treatment of Cao Shuo recently, Ma Jun's stuttering problem has been cured. He came to Cao Shuo with a very delicate hand crossbow.

Cao Shuo played with it for a while excitedly, and asked, "How many arrows can this quiver hold?"

Ma Jun's face was extremely ugly in an instant, and he said with a depressed face: "This subordinate is incompetent. At present, without increasing the volume, I can only hold fifteen."

Cao Shuo nodded. Fifteen pieces are already very good. As long as the first one is made and then gradually improved, more and more will definitely be installed.

"How powerful is the arrow?"

This is what Cao Shuo is most concerned about. If he can't shoot through ordinary iron armor, then the effectiveness of his hand crossbow will be greatly reduced.

Ma Jun said: "I tried it with the armor of Dong Zhuo's soldiers. It can be pierced within a hundred steps. The further the distance, the less powerful it is."

Cao Shuo thought for a while and said, "Find a pig to wear armor!"

"pig?"

Ma Jun looked surprised, and quickly asked: "Why use pigs, can't cattle and sheep work?"

Cao Shuo explained: "Pig skin is a bit thicker than human skin, but its outer surface is almost as hard as human skin. If you can put an arrow into a pig, then humans will have no problem."

"Your Majesty is really thoughtful." Ma Jun was in admiration.

Unexpectedly, the lord still has research on this, and then he ordered someone to find a pig, and then tried it.

"Whoosh!"

"Squeak!"

A pig weighing more than 200 kilograms kept screaming in the yard. Cao Shuo couldn't bear it, and ordered: "The arrows are used up, shoot it to death."

"promise!"

After fifteen arrows had been shot, the poor pig finally fell.

Cao Shuo walked over to look at the wound, he was a little dissatisfied with the power, after a hundred steps, he could only shoot about three fingers in.

After Ma Jun looked at the wound, he was also very dissatisfied. The damage was not bad at close range. It is estimated that it would not be able to hurt the person wearing the armor after more than eighty steps.

Cao Shuo took a look at the crossbow and said, "Think of a way to increase the power a bit. If it really doesn't work, start with the arrow."

However, Ma Jun did not disappoint Cao Shuo. In less than ten days, he improved the shooting performance of the crossbow.

The power of this experiment made Cao Shuo quite satisfied. Within a hundred steps, he could shoot and kill soldiers wearing leather armor without any problem.

As for Tiejia, apart from his Xuanjia Army, all the princes in the world can't get together 5 people.

Cao Shuo said with satisfaction: "The power is already good enough. Next, we will improve the problem of the arrow box and find a way to expand it to thirty."

Ma Jun asked puzzledly: "Your Majesty, if it is expanded to thirty, the weight may increase a lot."

Cao Shuo nodded and said, "It's inevitable, but I'm thinking about it for the city defenders. If you can research such a small one, then I believe you can also research it if it's ten times larger."

He planned to make several large crossbow bolts and fix them on the city wall.

"My subordinate understands!"

Cao Shuo said: "The fifteen arrows are just right for the cavalry to equip. You order the craftsmen to make some simple accessories. The core things are all made by the military machine room."

"promise!"

Two months later, the first batch of 1 repeating crossbows in the military engine room was completed. After being filled with [-] arrows, they weighed a total of [-] catties. The lightest weight possible.

Cao Shuo summoned five thousand tiger guards and distributed five thousand to them. Wang Ling asked Wang Ling to take them to the attribute performance.

Cao Shuo looked at Wang Chen and said, "Tomorrow morning, call the generals of each battalion to come and listen to the order!"

"promise!"

In the early morning of the next day, Cao Shuo looked at the civil and military ministers below and said, "Our army has been recuperating for two months. Now it is the beginning of autumn, and the weather has turned cold. It is a good time to send troops to attack the princes."

All the soldiers looked at Cao Shuo expectantly, wondering where the first stop would be.

However, many people have speculated that it should be said that Guangling County, after all, is the territory of Xuzhou, which has been occupied by Sun Ce, and he should go back to Jiangdong.

"Notify Gan Ning in Qingzhou to let his navy block all sea passages in Guangling County for me!"

Everyone guessed right, the lord wanted to beat Sun Ce.
