"Sir, are you okay?" Xiao Bai asked standing beside Zhang Nan. The obscene smile on Zhang Nan's face scared Xiao Bai.

"Ah? Xiao Bo? What did you say just now?" Zhang Nan heard a voice and turned around and found that Xiao Bo was standing beside him.

"I said, sir, are you okay? I saw you sitting alone on the ground and smirking. I felt something was wrong, so I came over and asked." Xiao Bai said.

"Laughing? Am I laughing again?" Zhang Nan touched his face and asked strangely.

"You haven't laughed yet, your mouth is grinning at the base of your ears." Xiao Bai said with a smile.

"Ah? Is that right? I was excited for a moment, excited for a moment, and couldn't control it." After Zhang Nan finished speaking, he looked at the crossbow in his hand and touched it, as if he was touching a rare treasure.

"By the way, sir, what is this? Is it a crossbow?" Although Xiao Bai had used a crossbow, and although the one in Zhang Nan's hand looked a bit similar to the crossbow, Xiao Bai didn't dare to confirm that it was a crossbow. After all, there was a crossbow where there was no place where crossbow arrows were set up.

"That's right, it's a crossbow, but this is not an ordinary crossbow. It's a crossbow that can fire three crossbow arrows at a time, and it can fire continuously." After Zhang Nan finished speaking, he handed the crossbow in his hand to Xiao Bai, "Come on, try it, tell me what you feel after using it."

Xiao Bai was not polite, so he took the crossbow and set it up. He shot the target in the distance without even aiming. He heard Zhang Nan say that he was shooting continuously, Xiao Bai was not in a hurry to see if he had shot. He fired continuously and stopped until there were no crossbow arrows in the crossbow box.

When he ran to the target, Xiao Bai discovered that the crossbow had shot through the target, packed up all the crossbow arrows, and ran to Zhang Nan with his things.

"How about it, evaluation." Zhang Nan took the crossbow and crossbow arrow from Xiao Bo's hand and loaded the crossbow arrow back.

"Artificial Artifact." Xiao Bo didn't say that much, he just simply said two words.

Zhang Nan smiled and said nothing. Zhang Nan naturally felt that the word "大天" that could be matched with the word "天票" was not the same aspect, there was no better equipment among individual soldiers' equipment.

"Okay, it's getting late. I'm going home. You continue to train with these kids and tell you quietly, have you seen the adult who came with me today?" Xiao Bai nodded, and Zhang Nan continued, "Actually, that's the emperor. I'm not afraid to tell you that the emperor is very satisfied with you. You can practice hard. It's a matter of time before you become an official in the future. I can put my words here."

After Zhang Nan finished speaking, looking at Xiao Bai with an excited face. Without waiting for Xiao Bai to speak, Zhang Nan quickly said, "I can only say so much to you. As for the competition, the competition has been cancelled, but you still have to practice. When I have other letters, I am arranging the next task for you."

Xiao Bo nodded, stood attentively, saluted Zhang Nan, and said, "Thank you sir."

Zhang Nan smiled, replied with a gift, and then returned to his mansion.

Back at the mansion, Zhang Nan had a few bites of rice and returned to his house and began to think about how to use this crossbow arrow. According to Zhang Nan's idea, the best way is to put the crossbow arrow onto the hot air balloon and cooperate with the air force to strike. However, this is just an idea. Although the hot air balloon is easy to make, as long as it has good sealing properties, this combustion gas tank is a big problem. According to the current steelmaking level of Datang, it is impossible to build a sealed gas tank, so this thing can only be supplied by itself.

Zhang Nan's initial plan was to exchange this combustion gas tank from the system and then install this set of equipment on the Tang Dynasty's earth-made hot air balloon. This not only saves costs, but also maintains the air power of the Tang Dynasty. Anyway, for the current Tang Dynasty, the air is simply safe and cannot be in a safe place. It is really a good idea to shoot crossbow arrows from the air to the bottom.

As for this continuous crossbow, Zhang Nan couldn't help Li Er, and at most he handed over this thing to the Ministry of Works for research. As for whether it could be researched, it was not Zhang Nan's responsibility. Anyway, Li Er would not cause trouble for himself, at most he was incompetent in the Ministry of Works.

With the hot air balloon and the continuous crossbow, Zhang Nan basically felt that there was no problem in dispersing the Turkic. The grassland was so vast that everything was visible when standing on the hot air balloon, and there was no place to hide. They were all living targets for the continuous crossbow. If flammable objects were sprinkled in the air, and at a glance, Zhang Nan was worried about the Turkic people.

Thinking of this, Zhang Nan seemed to have seen the bright future of the Tang Dynasty. After all, his ultimate goal is to be good at the Tang Dynasty and I, and finally earned a lot of money to take Cui Yue to live a rich life.

Thinking of Cui Yue, Zhang Nan remembered that he would go to pay Li Er a magic weapon tomorrow and go to the morning court. Cui Yue would definitely be idle when she came over tomorrow, so she handed Su Wen, and Zhang Nan ordered: "Old Su, if the wife comes to the mansion tomorrow, you can let her wait in the mansion. When the master I will come to the morning court, I will come back." After Su Wen said that he understood, Zhang Nan asked Su Wen to go down.

Sitting on the chair, Zhang Nan called out the system and looked at the hostile forces around the Tang Dynasty. Looking at the map, the Tang Dynasty's current confidants are the Turks and Tuyuhun, plus Xiangxiong. As for the Goguryeo, which was beaten by Emperor Yang of Sui but failed to be defeated several times, Zhang Nan also barely calculated it. In fact, Zhang Nan would not analyze it at all. It was just that the land area of ​​these countries was larger than that of the Tang Dynasty, so Zhang Nan listed them among the hostile forces. However, it is now hostile forces, and Zhang Nan is confident that they would all be included in the territory of the Tang Dynasty within five years.

The Tang Dynasty is still too weak now. It is a fool to eat so many countries in one bite. There is no way, so I can only do it step by step. First, start from the Tang Dynasty. First, we must improve the Tang Dynasty's technological level, first point all the skill points of the Tang Dynasty to technology, and then establish trade transactions centered on Chang'an, establish trade rules between the Tang Dynasty and surrounding countries. All transactions are carried out with gold and silver. Zhang Nan did this not because gold and silver are easier to circulate, but after the iron hoof after the Tang Dynasty stepped onto their country, it was convenient to bring the money back.

The more Zhang Nan thought about it, the happier he was. He wanted to say hello to Li Eryi now, but after looking at the sky outside, it was already dark, so Zhang Nan gave up his idea. Anyway, he would have to see his performance tomorrow. The performance was good and the support of the ministers in the court was the most important thing. Only when they recognized their plan of the Tang Dynasty from the bottom of their hearts could they proceed better according to their own ideas.
