"How? Where did the Goguryeo people go? Yang Xuan looked at the simple map in his hand and asked Fan Yue, the leader of the reconnaissance team who had just returned. Pen "Fun" Pavilion www.biquge.info

"Sir, the terrain here is complicated. There are mountains and valley bottoms everywhere, and small plains are formed, and we have now detected two Goguryeo people, one is a hundred miles north of us, and the other is relatively close to us, about seventy miles, according to the current speed of the Goguryeo march, I think, they will soon reach Lingyang Town at the bottom of the mountain, Lingyang Town is the best place I have seen to release poison gas, and other places. It seems that they are all too suitable. Fan Yue reported.

"Hmm." Yang Xuan wiped his chin at this time and looked at the map in his hand, this Lingyang Town is on the north bank of the Ling River, because it is convenient to get water here, so Lingshui Town was established here.

The location of Lingshui Town is actually exactly at the bottom of two hills, and the Ling River flows from the northeast to the sea in the southwest. No one knows the exact location, because the people of Yan don't know much about this land. Although this Lingyang Town seems to be called a town, it is actually only a few more households than other places, and according to his understanding, the total population of the town is no more than forty households.

"This place is indeed the best place to release poison gas, if we let go of the Goguryeo people and let them go down the mountain into Lingyang Town, we will be able to release poison gas if we have the upper wind." Zou Wen, the leader of the meteorological team, whispered. Because poison gas requires a lot of meteorological support, a meteorological team was established, in fact, the entire meteorological team only has seven people, four soldiers who carry things, two small officers who record data, and he, the leader of the meteorological team.

Yang Xuan wiped his chin and nodded. He also thinks it's a very good location. And it is very suitable for releasing poison gas here, because this is a valley, the poison gas stays for a long time, and it is not easy to drift up the mountain on both sides, and the killing power is greater.

Yang Xuan stood up at this time, but he still hadn't decided when to make a move. After all, there are still many unknowns that have not yet been determined.

His Einsatzgruppen only has a little more than a thousand people. Most of them were people who had been recruited to transport poison gas cylinders, and his team brought more than 8,000 poison gas bottles. As far as he knew, there was another special team like him, but he didn't know exactly where.

"That's right. Is there anyone else in town? Uncle Liu asked Fan Yue in a low voice.

"I guess not many people, if there are any, should have run away. This town, in fact, should be empty, there are very few people anyway. It is estimated that when the army arrives, it will be able to rest and leave the next day. If they go further west, about a little more than 200 miles, it is estimated that they will reach Xiangping, which is the logistics supply point of the army, if I am a Goguryeo, I will definitely pass through here, if I don't pass from here, if I go to other places, it is estimated that it will be fine, but the number of people will definitely not be too much. Fan Yue explained.

"Oh. If there is anyone, I am really worried that this poisonous gas will float over and poison many people. Uncle Liu nodded and said. And behind him, he carried all his protective gear, all of which was in his marching backpack. Inside the backpack, there is a gas mask made of leather, two glass lenses repeatedly sewn with a sewing machine on two large holes, and a large metal tube on the mouth and nose. Under the tube was a large jar with small mesh underneath, in which a large amount of activated charcoal was contained, which was the earliest gas mask. In addition, there is a full set of leather protective clothing, it is summer at this time, it is very inconvenient to wear, and it is very stuffy, if it is not for the danger of releasing poisonous gas, and the money is more, it is estimated that no one wants to do such a thing.

However, because the gas mask looks similar to a skeleton, many people call them skeletons. Because they look like skeletons, especially gas masks, which are really scary to wear.

"Oh. Liu Skull, I know you are venting poison gas, but don't let this poison gas go anywhere, I look at you, it's scary. Fan Yue avoided Uncle Liu and said. People call him Liu Skull behind his back, because it seems that the other party is really just like a skeleton, and the other party is the last person to release the poison gas, which makes everyone feel scared.

"If poison gas is released in Lingyang Town, when do you think it is best to release poison gas?" At this time, Yang Xuan asked everyone. The weapons used by his Einsatzgruppen are not guns. Instead, it uses poison gas, a weapon that has been used before, but the record is not very complete, plus it is almost played at will, and the people who release the poison gas are still poisoned for this, so the experience of releasing poison gas still depends on their own processing.

"I'll start with that." Zou Wen stood up at this time and said. His meteorological knowledge is just to start at Qin Guo Station and record data, but Yan Guo lacks such talents, so Zou Wen was arrested like this and became the captain of this meteorological team.

"As far as I know, this poison gas is pale green. In normal times, according to the density of the Qin people, it should be heavier than air. If that's the case, it's better to put it in the mountains. Best. Zou Wen thought about it and said.

"According to the meteorological knowledge taught to me by the Qin people, as well as my observations, this is a valley area, that is, there is a valley wind here.

"It's a valley wind during the day. The valley floor blows to the top of the mountain. It's a mountain breeze at night. The wind blows from the mountains to the valleys. In this case, the time can only be at night. And the wind can't be strong yet. If the wind is too strong, it will be blown away, but we just need to release the poison gas as hard as we can. Zou Wen said.

"Therefore, what I suggest is that we will do it at night, and if the Goguryeo people are resting in this town, we can give them a hard time, and release enough poison gas to poison them." Zou Wen looked at everyone and said.

"Good. Good. It depends on the direction of the wind, and if the wind changes during the day, our situation will not be good. What was supposed to poison others has turned into poisoning us, which is not good. Uncle Liu said at this time.

"Phew. Bah. You Liu Skull. Fan Yue said to Uncle Liu dissatisfied at this time.

"If you gassed me, I'll be the first to strangle you." Fan Yue threatened Uncle Liu.

"This meteorological officer is worthy of working in the Qin country, and he knows a lot. I think it's going to work. Uncle Liu said excitedly when he heard this. He was also afraid of poison gassing, so he preferred the wind to be in his favor.
