There were not many things in the three bags of sacks, but the workload was still huge when it was actually done. By the time the three of them finished grinding half of the sacks, it was already afternoon. All the officials of the Ministry of War were about to leave after get off work. The little official looked at Cheng Yaojin smashing things with bare shirtless, and they were curious, but they didn't dare to come forward to ask. However, Yuchi Gong, Li Xiaogong, and Li Jing surrounded the three of them and watched the three of them sweating profusely.

While watching Cheng Yaojin work barely, Yuchi Gong smiled at Li Jing beside him and said, "Senior Brother Yao, don't say it, this Yaojin is really good at doing work." After that, he laughed.

Li Jing also smiled as he looked at the three of them in a dirt state, but he didn't laugh out loud.

"Heizi, I'll tell you, Qingquan said this is a killing weapon, and told you that when you do it, you will be envious when the emperor rewards you." Cheng Yaojin didn't stop his work and said while knocking on saltpeter.

"Ha, I don't want this reward. I'm going to smash things in broad daylight. The emperor must give you this reward to you. There is a ghost." Yuchi Gong laughed, but he didn't leave, looking like he was watching the show.

Zhang Nan looked at the pile of powder around her, so she said, "Brother Cheng, take a break and see if it works first. These should be enough." After Zhang Nan said that, Cheng Yaojin threw the stone hammer in his hand aside, sat aside regardless of his image, and said, "I'm so tired."

Yuan Tiangang didn't take much effort, but asked: "Qingquan, can you let the old Taoist see how powerful this weapon is now."

"Master Yuan, don't worry, wait until I put these things into the bottle first." After Zhang Nan finished speaking, he took a wine bottle and stuffed the powder that had been grinding for a long time into the beer bottle one to two to three, and then made these three things a little bit more solid.

Zhang Nan picked up the bottle and shook it. He found that the things inside had been completely mixed and had been pressed into a solid porcelain. Zhang Nan picked up the bottle with satisfaction and said, "It's done."

Cheng Yaojin snatched the bottle and said in shock: "Qingquan, don't tell me, we have been busy all afternoon and have done such a thing. What can we do?" After that, Cheng Yaojin swayed the bottle.

"Brother Cheng, don't look at this thing, it's powerful. Why don't you find a dead pig? I'll put this thing under the pig's body to see how powerful this thing is." After Zhang Nan said that, he took the "grenade" in Cheng Yaojin's hand.

"That's fine, but there is no dead pig in this Ministry of War." Cheng Yaojin finished speaking and scratched his head.

"I said, two, what time has it been? You two won't go back to your house." Yuchi Gong, who was watching the fun on the side, was also bored and said to Zhang Nan holding the wine bottle.

When Zhang Nan saw the sky, it was already setting. He suddenly thought that today was the day when he accompanied Cui Yue back to the door, so Zhang Nan stood up and said, "Brother Cheng, why don't you do this now? Let's put this thing here first. Let's get a dead pig here tomorrow to do the experiment. I will accompany Yue'er back to the door today. It's still not too late, so I'll go home quickly."

Cheng Yaojin also looked up at the sky and found that it was getting late, so he said, "Okay, then I'll go back and get a dead pig to bring it to you tomorrow." After that, Cheng Yaojin was also ready to leave.

Just as Zhang Nan was about to leave, Yuan Tiangang grabbed Zhang Nan and said, "Qingquan, I don't know if I can come and see this thing when it is used tomorrow." Yuan Tiangang said with a smile.

Zhang Nan looked at Yuan Tiangang, who was a little dirty after working for the afternoon of work, and said, "Of course, if the Taoist priest has nothing to do, let's come and have a look tomorrow."

"Since that's the case, I'll thank you." After Yuan Tiangang said that, he bowed to Zhang Nan and left.

When Zhang Nan saw that everyone was going back to their own houses, he quickly walked towards his mansion. When he returned to the mansion, Cui Yue had already been waiting in the front hall. When he saw Zhang Nan enter the door, Cui Yue greeted him and said, "Your husband, what are you doing? Why did you come back so late? Didn't you go back to my house today?" Cui Yue said with some blame.

"Oh, it's all my fault. I've forgotten the time when I made a small thing in the Ministry of War." After Zhang Nan said that, he kissed Cui Yue in the face and compensated him at that time. Zhang Nan would not say that he had forgotten the return to the door.

However, it was obvious that Cui Yue would not buy Zhang Nan’s account this time: "Oh, husband, go and wash your face quickly. What is the face on it, it’s dark." After Cui Yue said that, she urged Zhang Nan to wash her face quickly.

After Zhang Nan washed her face, she set off with Cui Yue with gifts. It was already autumn and it was darker quickly. By the time she arrived at Cui Mansion, the sun had already set, while Cui Shao and Cui Lu stood at the gate waiting for their daughter to come back.

Seeing Zhang Nan and Cui Yue coming, the two of them quickly asked Zhang Nan and Cui Yue to enter the mansion.

"Oh, Yue'er, I miss you so much." Cui Lu said with red eyes as she looked at Cui Yue. Although she had not seen her daughter for only three days, Cui Lu felt that she had been as long as three years.

"By the way, why did you come back so late today?" Cui Shao looked at the sky and said.

When Cui Yue heard this, she said, "It's all about Langjun. When he comes back from the Ministry of War, the sun will start to set." Cui Yue said with a grievance.

"Oh, Qingquan, is there anything big happening in the Ministry of War today? Why did it even postpone the return home?" Cui Shao asked strangely. It is not surprising to work overtime, but it is very strange to work overtime in his own workplace. Generally, there are things that have not been completed, Cui Shao will take back to his own home to do it.

"No, it's just that I got a little thing today and forgot the time for a while." Zhang Nan scratched his head embarrassedly and said.

"Little thing? What little thing?" Cui Shao said curiously. He had only made hot air balloons, but now he was curious about what Zhang Nan said.

"It's just a weapon. I thought it would be better to use it with a hot air balloon." Zhang Nan thought for a while and said. At this time, the four of them were already sitting in the hall. Zhang Nan looked at the dishes on the table and swallowed, saying that he had been busy for a day and had not even eaten a serious meal. Now that he saw what he had eaten, he felt hungry.

"Hot air balloon? What is a hot air balloon?" Cui Lu asked strangely.

"Hey, don't talk about the secrets in the court." Cui Shao reminded.

After Cui Shao finished speaking, he caught Cui Lu's eye rolling, and then Cui Lu served Cui Yue a bowl of rice and said, "If you don't say it, don't say it, come on, Yue'er will have a meal."

"Qingquan, it's good that you have this intention, but I'm telling you how to do things, how are you doing?" Cui Shao asked.

"Things? What's going on?" Zhang Nan said.

"It's what you are going to go to the battle." As soon as Cui Shao said this, Cui Yue's chopsticks fell to the ground with a clang. Then Cui Yue asked in surprise: "Mr. Lang, are you going to go to the battle?"
