"Eh, Senior Brother Yao, how can you say that, I haven't worn it for a few days. Pen, Fun, Pavilion www.biquge.info" Cheng Yanjin quickly said when he heard Li Jing expose his shortcomings.

"Haha, it's okay, it's okay, Qingquan is not an outsider, but Qingquan, the old man is also in good spirits when he wears this camouflage uniform, whether it's horseback riding or activity or something, it's very convenient, but the defense is not good, eh, it's a pity, but the old man also likes to wear this dress very much at home, and it's very comfortable to wear." Li Jing said with a smile.

"Don't talk about these useless things, come on, Qingquan, brother will take you to see my soldiers, let you see what it means to be a mighty army." After Cheng Yanjin finished speaking, he pulled Zhang Nan up, ready to let Zhang Nan take a look at the Qianniuwei trained under his hands.

"Brother Cheng, are you kidding, it's also called a mighty master, it's not like you haven't seen what Huai Mo looks like after training." Zhang Nan said with a look of surprise that Zhang Nan didn't expect Cheng Yanjin to dare to say that the people he trained were mighty after seeing the soldiers trained according to modern methods.

When Cheng Yanjin heard this, he immediately blushed and said: "What's the matter, you are the twenty-one person, and you are still talking big here." Cheng Yanjin still wanted to save a little face for himself.

"Brother Cheng, it's not like you don't know that the current military academy students are training hard, and it won't be long before these twenty people will become two hundred." Zhang Nan said with a smile.

"Hmph, it's boring, it's boring, don't talk about it." As soon as Cheng Yanjin heard that Zhang Nan had collapsed his stage so ruthlessly, he immediately didn't want to continue this topic. When Zhang Nan heard Cheng Yanjin say this, he smiled and didn't say any more.

"By the way, Qingquan, apart from that hot air balloon, do you have any more powerful weapons?" Cheng Biting Jin Shen mysteriously approached Zhang Nan's side and asked.

"This is naturally there, Brother Cheng, why are you asking this." Zhang Nan asked strangely.

"Isn't this a long-term experience, that hot air balloon makes me like it, Qingquan, can you help me get one." Cheng Yanjin rubbed his hands and said.

"This, Brother Cheng, it's not that I don't want to give it to you, but I don't dare to give it to you, the emperor has said that this thing is a secret weapon, I want to give you one, and the emperor won't peel me off." Zhang Nan said.

When Cheng Yanjin heard this, it seemed that the same was the case, so he said: "If you don't give it, you won't give it, then you have to let Brother Cheng see other secret weapons." ”

"This ......" more powerful weapons, Zhang Nan is not without them, just like the system even has airplanes, cannons, and aircraft carriers, but Zhang Nan just looked at it, and couldn't take it out at all, after all, the points needed for this are astronomical, even the simplest thermal weapon, the earthen pistol, Zhang Nan doesn't want to change, because it's too much of a loss.

"What's wrong, what's wrong?" Cheng Yanjin asked strangely.

"Brother Cheng, I really can't take it out for you, but I can describe to you what that thing looks like." Zhang Nan thought about it and said.

"Come on, come on, talk quickly." Cheng Yanjin urged, in fact, Cheng Yanjin didn't think that Zhang Nan could get one for himself, and it was not bad to listen to it, so he should have fun. Li Jing, who was sitting above, was also interested, took a sip of tea, and waited for Zhang Nan to say this more powerful weapon.

"It's just something so big, it's light, and you can hold it in your hand." After Zhang Nan finished speaking, he raised his slap and continued: "Within fifty steps, as long as you shoot your body, you will definitely die, and if you shoot your head, you can break your head." "That's right, what Zhang Nan said is a normal pistol.

"Qingquan, you're really telling a story, can you kill people with something as big as that? It's still less than fifty steps, and I think it's hard to kill someone within five steps. Cheng Yanjin obviously didn't believe that such a weapon would exist in this world.

Zhang Nan ignored Cheng Jinxiang and didn't believe it, after all, he didn't see the real thing, and it was still very difficult to make these people believe it.

"There is also a kind of weapon, hold it in your hand, throw it out, if it is thrown next to a person, if it happens to be thrown into that person's hand, the gas generated by this weapon will instantly blow up the arm and even the upper body, and there is no chance of survival." Zhang Nan continued.

"The more I talk about it, the more unreliable it becomes, and I don't believe it." Cheng Yanjin looked like Zhang Nan had deceived him, and he had no desire to listen to it anymore, and then got up and sat aside.

After Zhang Nan finished speaking, he was also stunned, he seemed to have talked about something crucial, but he couldn't grasp the key point.

"Pistols? Hand grenade? Zhang Nan repeated these two words in his mouth.

"That's right, grenades, the gunpowder contained in the grenade, you don't have to buy it from the system at all, the existing things in the Tang Dynasty can completely get this thing, with black powder, it is the first step towards a thermal weapon, although this thing will be used in the military at the end of the Tang Dynasty, but now it is still a new weapon that does not exist at all." Zhang Nan muttered to himself.

Cheng Yanjin obviously didn't hear what Zhang Nan was saying, but he just saw Zhang Nan looking stupid, which frightened Cheng Yanjin, why was he still stunned? Cheng Yanjin walked to Zhang Nan's side, shook Zhang Nan's body and said, "Qingquan, what's wrong with you?" ”

At this time, Zhang Nan reacted, and then said with a look of surprise: "Brother Cheng, I want to thank you." ”

"Thank me? Thank you for what I do? Cheng Yanjin said with a puzzled face.

"Thank you for adding a big killer weapon to my Datang." Zhang Nan said in surprise.

"What did I do?" Cheng Yanjin still looked puzzled.

"I thought of a more powerful weapon, with a hot air balloon, not to mention the Turks, as long as it is made, it will be invincible all over the world." Zhang Nan said with a smile, if you throw explosives from a hot air balloon, it will be an earth-made bomber of Datang.

"Tell me, what's the killing weapon?" Cheng Yanjin asked.

"Let's not talk about this first, Brother Cheng, you can help me find a few things first." Zhang Nan said.

"Oh, what do you want?" Cheng Yanjin asked.

"Sulfur, saltpeter, charcoal, just these three things, it's better to get some empty bamboo." Zhang Nan thought about it and said that although these things can be replaced from the system, Zhang Nan still asked Cheng Yanjin to find it on the spot in line with the principle of saving what can be saved.

"Does this thing have anything to do with a killing weapon? Isn't this all for alchemy? Do you want to do alchemy? Cheng Yanjin asked strangely.

"Eh, Brother Cheng, you can help me find it, and tell you, this thing is definitely a killing weapon, if this is made, it will be an invincible existence now." Zhang Nan hurriedly said that now Zhang Nan can't wait to start his own scientific experiments.
