The defensive battles of Qingzhou and Xuzhou were won without Gongsun Kang. It can be seen that the elite soldiers and fierce generals in Liaodong can already be on their own.

Of course, the princes did not go out in person, and the whole army pressed on. All sides are sending generals to try to attack. found that Liaodong was a hard bone, so he stopped fighting and did not let the situation escalate.

After all, there are still princes such as Zhang Yang, Liu Biao, and Gongsun Zan around, and you can try to attack them to see if you can bite the next bite of meat.

In addition to the remote command of Liaodong, Gongsun Kang also pondered the upgrading of armaments.

He took inspiration from the platoon guns of later generations: could it be possible to invent a platoon crossbow arrow? A crossbow chariot that can fire from 10 to 50 bed crossbows at a time?

Of course, the power to fire crossbow arrows can no longer use animal tendons, and springs can be used.

Gongsun Kang, who was in his previous life, disassembled the alarm clock when he was a child. When the steel sheet is wound in circles, it has a lot of elasticity. After winding the clock and compressing it to the extreme, it can also gradually release the power, which can go for several days.

If this principle is applied to ballistas, is it possible to produce crossbow arrows?

The more Gongsun Kang thought about it, the more excited he became, and hurriedly summoned Li Shanchang, Zhang Huaiyuan, Zhang Yong, and Cao Huachun. Explain your ideas and see what they have better suggestions and needs.

Zhang Yuanhuai, an expert in weapons manufacturing, pondered for a long time after listening to this, and then said: "At present, Liaodong has refined a variety of metals, and we have also tried to add different metals to the molten iron to produce alloy steel with different flexibility and strength. Therefore, it should not be difficult to produce elastic steel sheets. ”

Zhang Huaiyuan's commitment solves the core problem of power source. It made it possible for Gongsun Kang's idea to be realized.

Li Shanchang also spoke: "At present, there are enough craftsmen in Liaodong, and rich experience abounds, and there is no problem with manpower. I can draw people to form a research team. ”

Zhang Yong and Cao Huachun were soy sauce players, and they didn't understand why they were allowed to participate in this kind of meeting, so they listened respectfully, but they didn't dare to speak indiscriminately.

Gongsun Kang glanced at them and explained to them: "Huachun must do a good job in the secrecy of scientific research, this platoon ballista is a big killer and can change the pattern of the world." The participating craftsmen should be closely monitored, and there can be no leakage! ”

Cao Huachun hurriedly stood up and clenched his fists with both hands: "No! I will definitely send more people to do a good job of surveillance. ”

Then he smiled at Zhang Yong and said: "Jingyun will be familiar with the manufacturing process of various products in the future, and when the world is peaceful in the future, I will set up a science and technology department to let you be in charge." ”

Zhang Yong also hurriedly got up, followed Cao Huachun's example, and replied respectfully: "No! ”

Gongsun Kang's arrangement for Zhang Huaiyuan in his heart is: Minister of Ordnance Industry; And Li Shanchang's arrangement is one of the seven cabinet members.

These arrangements did not say anything to the two of them, but they did not affect their loyalty to themselves.

The matter was settled, and the four of them went about their work. And Gongsun Kang is waiting for the result. Things can't be done in a short period of time, so you need to let it go.

Gongsun Kang summoned Qiao Rui to meet.

Qiao Rui, as a general under Yuan Shu, has made certain achievements for Yuan Shu to open up territory.

But because of Yuan Shu's premature defeat, none of his generals left a great name in history.

After Gongsun Kang understood the whole process of the battle of Guangling County, he believed that Qiao Rui still had strong adaptability and command ability. So I want to take him down.

The bridge itself surrendered, so it didn't take any shelf.

Entering the lobby of the Champion Hou's Mansion, Qiao Rui saw a majestic young man sitting on it, and knew that it was the Champion Hou. Immediately knelt down on his knees: "Meet the champion Hou!" ”

Gongsun Kang nodded secretly, very satisfied with Qiao Rui's acquaintance. said, "Get up, sit down and talk." ”

Qiao Rui thanked Gongsun Kang and knelt down on the mat, he didn't understand that the high-backed chairs placed under the hall could also be sitting. Just like Gongsun Kang, who is sitting on a high-backed chair right now.

Gongsun Kang and Qiao Rui talked about military strategy and governing the place, and found that Qiao Rui still had a certain level of command of war; They also have their own unique views on governing the place. It seems that he can be qualified for the defense of any county.

But Hashirui had just surrendered, and he didn't know his character yet. The historical record is too small, and it can be used with confidence like the ban.

Gongsun Kang thought about it for a while, and said: "Wadao is also our territory, there are no generals there, and we need talents like you who can stand alone." I appoint you as the Governor of Wadao, to be in charge of the military there, and to assist Zheng He in governing the Wa people. ”

Qiao Rui hurriedly knelt down, "Thank you, lord!" ”

Gongsun Kang said again: "Your family, we have sent someone to fetch it, and the news of your surrender at that time has not yet spread to the Huai River, so there should be no problem." ”

Qiao Rui thanked again and said that he had done his best to Gongsun Kang and died.
