Liu Tan thought about it and realized that it was indeed not easy to improve the tread crossbow. However, he remembered that there was a legend in history that Zhuge Liang had invented the Zhuge Crossbow, which had great lethality. Unfortunately, it was lost later and he still didn't know whether it was true or not.

I feel like this thing is just like the wooden ox and the flowing horse, it only exists in legends.

However, Liu Tan tends to believe that this thing really existed. After all, many people said that the secret color porcelain did not exist back then. The discovery of the underground palace of Famen Temple slapped many people in the face.

Maybe these things are buried somewhere in China and have not been discovered yet.

Liu Tan patted Gongshu Yi on the shoulder and said, "Don't be too stressed. Just give it your all. If you can improve, even just a little bit, I'll give you an official position."

Gongshu Yi raised his head and asked, "Your Highness, is what you said true?"

Liu Tan laughed and said, "When did I ever break my promise?"

Strictly speaking, the crossbow is for Liu Tan to play with. Even if it is equipped to the guards, it is not within the scope of military supplies.

Because its range is too short, it is easy to accidentally hit a friendly unit at this distance on the battlefield. Anyway, there is a bow, so this is not the first choice.

Liu Tan couldn't give Gongshu Yi an official title just because of the crossbow. Even if he could, it would only be an official position in the royal palace, which was not a good step for Gongshu Yi and others to advance.

But the tread crossbow is different. If it is really improved, it will be equivalent to improving the combat capability of the Han army, so of course it can be given an official position.

Gongshu Yi was a little excited and said without saying anything difficult, "I will definitely try my best!"

Even if he can't do it, there are people in their family who can, and the elders haven't taken action yet!

Official positions are too attractive to the Gongshu family. They have been searching for so long just to become an official, and they cannot be jesters.

No family has prospered by relying on jesters. Even if they could, no one would want to bear the name of a jester's family. But the problem is that the Gongshu family does not want to lose their ancestral craft. As mechanical technology becomes less and less popular, the things they make have penetrated into every aspect of the lives of the nobles, but no one remembers them.

Under such circumstances, it was not easy for the Gongshu family to seek official positions.

Not to mention Chang'an, the princes... none of the princes take them seriously!

Now there is finally a Northern King who is willing to use them, and we must work hard to do so.

Gongshu Yi decided to write a letter home as soon as he returned. They could not make a decision casually on a large weapon like a foot-stepping crossbow. They had too little experience. If it looked good during the test but failed on the battlefield, even killing them would not be enough to save it.

Wei Deng watched Gongshu Yi leave in a hurry, then turned to Liu Tan and asked, "Your Highness, are we going to join the crossbow training next?"

Liu Tan nodded. "This is very useful. It will be useful in individual combat in the future. By the way, when you return to the capital, select a few of the most outstanding guards to escort Jiang Tingwei back to the capital. Then have them obey Jiang Tingwei in everything. If Jiang Tingwei asks them to beat someone up, they don't have to worry about anything. Just do it and leave the rest to us."

Wei Deng looked up at Liu Tan sharply and asked, "Your Highness, is someone in Chang'an saying bad things about us again?"

Liu Tan laughed immediately. The word "again" was used so well. However, he continued, "Not really. It's just a precaution. You know Jiang Tingwei's situation. He might be bullied, but how can we, the people of the Northern Border, be bullied? Not to mention, he's the hero of this negotiation."

Wei Deng understood and responded, "I'll immediately select the few who are most capable of fighting!"

Liu Tan waved at him and said, "Go ahead."

Wei Deng turned around and left. After Liu Tan finished giving his instructions, he turned around and started studying his lantern.

Although it is still early for the fifteenth day of the first lunar month, it does not mean that lanterns can only be hung on the fifteenth day of the first lunar month.

He planned to decorate Liu Che's palace with some lanterns, and even organize a lantern festival for Shuofang City when he came. After he saw it and thought it was suitable, he would hold it at the trade fair, which could also be a gimmick or something.

Well, opening on the fifteenth day of the first lunar month, and having a prosperous Lantern Festival, that’s a great idea.

In fact, making lanterns is not difficult. Since he has nothing to do anyway, he might as well do it himself.

Directly use soft bronze wire to bend out the desired shape.

When Liu Tan was making the lantern, Gun Gun was playing beside him. He simply made a lampshade shell in the shape of Gun Gun, making it the same size as Gun Gun, then covered it with white paper and painted the patterns on it with ink.

GunGun watched curiously as a paper panda about the same size as itself came out of the oven. After Liu Tan finished drawing it, it seemed to have misunderstood something. It barked at the paper panda twice and even hit it with a stone, making a hole in it and knocking it to the ground. However, it still refused to give up and tried frantically to escape.

Liu Tan had no choice but to walk over and push the rolling big head and said, "You can't even tell the real from the fake, are you stupid? That's you!"

GunGun took the opportunity to hug Liu Tan's waist and refused to let go. Liu Tan was almost carried into the panda park by it, and quickly asked someone to pull GunGun off him.

Gun Gun was very dissatisfied with this and turned his back to Liu Tan and refused to look at him.

Liu Tan's mouth twitched. Ever since this guy arrived in the Northern Border Kingdom, all his worries have disappeared. He has good food and drink, and his flesh is growing very fast.

It wouldn't be a big deal if it just gained weight, because the territory Liu Tan had drawn for it was huge, second only to the size of the main hall, and he had also designed a lot of enrichment toys, so GunGun played with the toys every day as if it were exercise. Not only did he gain weight, but he also developed a body full of tendons. Liu Tan didn't think he could beat him with that kind of strength, but as for Lu Xuan... he could give it a try.

He reached out and patted Gungun's head, deciding not to make a panda lantern in front of it or let it see it. This guy was not good at anything else, but he was extremely jealous, which made Liu Tan worried. How could he find a girlfriend in the future if he was so xenophobic?

After GunGun received the tender bamboo that Liu Tan fed him, he turned around and tried to hug Liu Tan again. This time, Liu Tan was quick enough to jump out of the panda enclosure and run back to his study.

Unexpectedly, the door of the panda park was not closed in time, and Gungun rushed out directly from inside and caught up with Liu Tan.

Liu Tan originally thought that it was going to grab his legs again, so he dodged for a moment. However, he didn't expect that this time Gun Gun had learned his lesson and ran straight towards his study.

Liu Tan originally wanted to catch up with it and drag it back, but he didn't expect that he couldn't catch up with GunGun along the way!

GunGun ran with a racing feel with its seemingly clumsy body. Not to mention Liu Tan, even the breeders who were chasing after him and who specialized in raising GunGun couldn't catch up with it!

Liu Tan looked at the black and white ball running into his study in confusion, with one sentence echoing in his mind: Is this reasonable?
