"Only in this case, Zhao Jun will have to dispatch a large number of troops to complete such a task. I am afraid that military expenses cannot be afforded." Li Mu said worriedly.

"Moreover, Zhao Jun's troops have already deployed 20,000 people. At present, Zhao Jun, who has only 80,000 people in the country of Zhao, is serving as the main defensive task, and his troops are extremely weak. I am still a little worried about this, so I had better think of a solution , Can solve this problem." Li Mu said at this time.

Faced with the problem of a large number of prisoners of war becoming slaves brought by Goguryeo. Li Mu thinks it is feasible, after all, Qin has great demand in this regard. He knew that the railway company of the Qin State needed a large number of slaves to expand its manpower. The demand in this area exceeded any period, and the demand for railways was quite large.

"In this case, there is nothing we can do." Li Zuoche said regretfully, shaking his head. This is the best way he came up with. Because the opponent is actively attacking, if the opponent bypasses his own defense line, then Zhao Jun can continue to increase the defense strength. After cutting off the opponent’s retreat, as long as he lays an ambush, he will definitely be able to capture a considerable number of Goguryeos as prisoners of war. These prisoners of war are sold to the people of Qin at a fair price.

"It's not that there is no way, but the way is in the hands of the nobles of Zhao State." Li Mu said at this time.

"What do you mean?" Li Zuoche had already given up.

"Nobles, there are some private soldiers in the hands of the nobles. They can do such things. As long as we release the news and make them think that it is profitable, they will actively do it. The captured slaves are sold to the people of Qin, and the people of Qin are also happy. , This matter must be let go. As for how to do it, it is our business." Li Mu thought for a while and said with a smile.

"Yeah." Li Zuoche nodded. For such a result, it is already very good.

Yan State, a paper mill fifty miles north of Yandu. This paper mill was jointly established by the people of Qin and Yan.

"Are you the manager of this house?" An officer of the State Yan asked Qin Guoren who was looking at the paper mill coming out.

"Yes. I'm the manager here. I don't know the sir." The manager asked puzzledly. He is a native of Qin and is protected by Qin. People in Yan can't catch them casually. It is with this protection that his factory can be produced in Yan. The paper produced here is mainly supplied to Zhao and Yan, and exported. When I arrived in Qin, because it was densely forested, mountainous and rivers, the biggest raw materials for papermaking were available. And the workers here are not well paid. Just in time to open a paper mill.

"We need your chlorine gas tanks. We will give you a very fair price. We will take as much as you have." At this time, the officer said.

"Chlorine tank, what do you want that thing for? That thing is poisonous, and you don't bleach it. The oxidizing property of this thing is very?????" The manager also wants to explain further, after all, this thing is too toxic and he is afraid of killing people. , When he used it before, he repeatedly emphasized not to move randomly. So as not to cause more damage.

"Don't worry about that much? You just have to sell us the chlorine tank." The officer said impatiently.

"This. It depends on the price you give?" The manager nodded at this moment. He believes that this is nothing. Chlorine is easy to produce in Qin. It can be obtained by decomposing sodium chloride solution with direct current. Not only that, this chlorine gas is relatively easy to compress, and it is easy to transport when compressed into a cylinder. The bleaching effect is not bad. So many paper mills use this thing for bleaching.

"On the basis of your cost price, add 50%. We will charge as much as you have," the officer said.

"Okay. That's it for you." The manager nodded and said.

"We want it now," the officer said.

"Yes, did you bring the money?" the manager asked with a smile.

"This is naturally easy to say." The officer said. The next two went to see the goods, and then paid and withdrew and left. There are still many such paper mills, and Yan Jun quickly collected as many chlorine tanks as they thought were sufficient, about 10,000 bottles. After use, the jar will be refunded and there will be a large jar deposit. It can be said that Yan State spends relatively little.

"I really don't know these Yan people, they are going crazy. What do you want so many chlorine cylinders for?" A paper mill manager told another on the second floor of a restaurant.

"That is, I feel crazy too. This chlorine gas is too toxic. What do you want this thing for? Do you want to bleach it?" another factory manager said curiously.

"Who knows, but, I remembered one thing, this country of Yan seems to have let go of the poison gas before, you said, are they used to let the poison gas go?" the factory director who started it asked suspiciously.

"Yes, this is possible." Another factory director said with a pat on his head.

"Quickly, let's take a telegram and talk about this." The director went downstairs anxiously.

Qin State Xianyang. Inside the prime minister's house. Feng Jie submitted a report to Shang Wen. This report is aimed at Yan Guo's wanton purchase of chlorine gas tanks.

"Damn it. These Yan people thought of releasing poisonous gas. The release of poisonous gas is almost addictive." Shang Wen said with some annoyance.

"We have resolutely opposed the use of chemical poisonous gas by the Yan people, but the other party actually did so!" Shang Wen was extremely annoyed by the chemical poisonous gas, so Shang Wencai resolutely requested Yan State to stop and prohibit the use of chemical poisonous gas, but the previous treaty Meng Yi felt that the conclusion was a bit hasty and there were many loopholes.

"I think it seems that the people of Yan people will use these poisonous gas on the Goguryeo people. After all, their situation is very unoptimistic." Meng Yi said while looking at the report.

"It won't work on anyone. You don't know the harm of this chemical gas." Shang Wen said.

"However, the last treaty stipulated that the people of Yan and Qin were not allowed to use it in the Central Plains. But this time it is aimed at the Goguryeos, who are not from the Central Plains. They are aliens. Such a treaty is not legally binding." Meng Yi said to Shang Wen.

"Besides, our Qin State has such conditions, why don't we give special consideration to this matter?" Meng Yi asked, looking at Shang Wen.

"You know, we also have some hard to solve problems. If we sign on it, we will be in trouble. But we are targeting a small number of people. Such use. I don't think it is too much." Meng Yi said to Shangwen To.

"I think it's too much." Shang Wen said.

"I think this matter should be considered by the General Staff. After all, they are military experts." Meng Yi suggested.
