Chapter 579: Yellow-green fog

When Qin's senior officials dispatched planes to participate in the war, Yan finally acted. They will use poison gas for the first time.

"How is the weather tomorrow? I want to know in advance." Ju Xin came to the front line of the Yan army with a secret weapon. This frontline is an open field. Only in the direction of Qi Jun, there is a small highland of more than 100 meters high. This highland is insignificant, but it can overlook all the surrounding conditions. The mobilization of the Yan army's forces is under the control of the high ground.

And this area is right in the middle of the two weather stations in Qin State. Therefore, Qin State usually sends a meteorological team to measure the meteorological data here by the way. Ju Xin visited the Qin State's weather control area. In the end, we finalized this place with some high-level military officers. Because this place is on a flat ground, there are more people defending. There are probably more than two thousand Qi troops, and the rebels jointly defended the area.

"Tomorrow's weather? Wait a minute, my lord, I'll check it for you." Qin Jun's weather officer checked the information.

"I'll look at the isobars." The weather officer said.

"Sir, is that drama master again to check the weather?" a deputy asked.

"Yes. Who knows what this adult thinks, come to ask about the weather every day." The weather officer was a little annoyed.

"How's the weather conditions lately?" the weather officer asked.

"A ridge of high pressure has passed. It is fine and suitable for flying. But we have no mission." said the deputy.

"Well, such high weather seems to be maintained for several days." The weather officer said.

"I think so, but there is a slight breeze. It's north," the deputy said.

"I see. I'll tell this adult." The weather officer casually took a piece of weather data and said. Obviously the weather officer has suspicions to deal with. Because Qin's meteorological observatory needs to build many to fully unveil the mysterious veil of weather, this is only initially established in Qin. And here, it's terrible. Qin Guo only sent a platoon with about forty meteorological personnel. These personnel can only provide extremely limited meteorological data. And usually the current affairs are very poor, there is a great risk of accidents. Fortunately, the communication between winter and spring. Just pay close attention to the situation in the north. Especially the report from Xianyang.

The meteorologists of the Qin State gradually discovered that Qin’s cooling was mainly due to the oppression of the two same high-pressure systems in the west and the north. Considering the cold place in the north, they regard it as cold air. It was the existence of this gas that caused Qin Guo to cool down. This shows that Qin's meteorological observations are still incomplete. And the room for improvement is very large. This is mainly limited by the transmission and understanding of meteorological data.

Meteorological data is usually calculated once a day. If it's farther away. It takes three to seven days. When these materials arrive. Meteorological phenomena have often occurred. It is this kind of primitive data that gave Qin State Meteorology a solid cognitive process.

"My lord, the situation is like this. The last time a high-pressure ridge passed hasn't been long. We are now in the range of high-pressure control, and the range of high-pressure control is usually sunny. In other words, the next few days will be good weather. The weather officer said with great gesture.

"Oh, is it windy?" Ju Xin asked.

"Wind. Yes, breeze, northerly wind." The weather officer said.

"Wh, what wind?" Ju Xin didn't know what the weather officer was talking about, what high pressure ridges and high pressure controlled or what. He didn't even know. But just know that the weather is fine and there is wind.

"Northerly wind. It is likely to be northwesterly." The weather officer explained.

"Which direction?" Ju Xin asked excitedly. One of the conditions has been met.

"That direction." The weather officer pointed to the direction of Qi Guoren.

"Okay, thank you, thank you. I will reward you later." Ju Xin said excitedly. Then excitedly left Qin State's weather station. The weather officer looked at this guy strangely.

"I'm sick." The weather officer said.

He took a bottle of soda and left.

The time to release the poisonous gas has finally come. finally come. Ju Xin exclaimed happily in his heart. Although he couldn't call it out, he was excited enough. This weapon is powerful enough to achieve a great success.

Ju Xin began to secretly prepare.

In the early hours of the morning, a very strangely equipped team walked into the Yan army's position. They were wrapped in cowhide all over. Only two glasses are included for the eyes, and there is a huge metal disc in the area of ​​the nose and mouth. It seemed very scary. Many Yan Army soldiers stared at these strange troops in a daze. They are more scary than ghosts.

And they carried the cylinder into the position without hesitation. Some people also had weird metal pipes. These people were all wearing chemical-gas protective clothing from the early Qin Dynasty, and this chemical-resistant clothing did not play much role at all.

Only the activated carbon in the gas mask still has some effects. Qin's water plant not only uses chlorine, but also uses activated carbon. The filtering effect of activated carbon has been recognized by the people of Qin. The people of Qin are very aware of the harmfulness of poisonous gas. Therefore, when they do the synthesis of chloride, they usually do it in a sealed space. But even so, it often causes some people to be slightly poisoned. The reason is that some places need to be checked manually. In order to avoid casualties, this kind of protective clothing with great psychological comfort but a little effect appeared.

A royal guard of the Yan Army took on this heavy burden. Many of them have seen the cruelty of poison gas, and many of them have been unable to eat for many days after seeing it. There are also many people asking to withdraw, but those who withdraw are all killed. To prevent leaks. To comfort these people. Yan Guo ordered such a suit.

With this kind of protection, these people are finally a little more stable.

"Listen, we will deflate before the sun comes out." Ju Xin said protectively. He left after speaking. The protective clothing is boring. And also can't breathe.

Early in the morning, the sun had not yet come out, but there was already some brilliance in the east, and a soldier of the Qi army yawned to check the surroundings.

Staying up all night made this Qi army soldier a little tired. He was like a nap, but the leaders of Qi Jun were very strict. Those who slept secretly lost their heads in their sleep. This is a battle to defend the soil. The soldiers of the Qi army controlled their tiredness.

"Let's see what's new." Qi Army soldiers stepped on a mound and looked at the Yan Army's position. This look awakened him a lot.

The yellow-green mist slowly drifted towards Qi Jun.

"I, we're wrong." The Qi Jun soldier rubbed his eyes vigorously with his hands.
