Ye Han did guess correctly, the effect of poisonous gas on the giant insect was also obvious, the giant insect close to the chemical plant first lost its sense of balance, staggered like drunkenness, and then lost control of its limbs, fell to the ground and couldn't get up, and at this point, the giant insect was not far from death. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

After a while, a circle of giant insects fell outside the chemical plant, the number of which was no less than four figures, and there were still giant insect moths rushing towards the chemical plant like flames.

It's not surprising that poison gas works on giant insects, and what is the matter with giant insects that they would rather die than run to chemical plants?

Although the giant insect has no intelligence, any kind of creature has the instinct to seek advantage and avoid harm, and the giant insect has no reason to run over and send it to death.

Could it be that there is something in the chemical plant that attracts giant bugs?

Ye Han immediately asked on the radio: "Call Wulian, please answer when you hear it!" ”

"Five companies received, please speak!" Jian Shuyu hurriedly replied.

"Ask the people at the chemical plant if they have anything to do with giant insects."

"Won't it?" Jian Yushu muttered in surprise, and replied after a while, "Chief, ask clearly, they said that there is a tanker truck transporting insect liquid in the factory. ”

Ye Han suddenly realized that the reason had been found!

The so-called insect fluid is the liquid extracted from the canopy of the insect tree, when it first started to deal with the insect tree, it was directly destroyed the tree, but with the passage of time, the laboratory gradually found that the insect liquid has a very obvious effect on the evolution of insects, which can increase the success rate of ordinary insects by four times!

Although the success rate of six times the giant is only 20 percent, for the giant experiment conducted in the laboratory, it is a four-fold increase in cultivation efficiency, which can save a lot of time and save a lot of manpower and material resources.

The demand for insect fluid in laboratories is very large, and the military will try to collect insect fluid for laboratory use when conditions permit.

When the insect tree was everywhere in May, no one collected this thing at all, and when the laboratory had a need, the insect tree was either destroyed by the military, or it was close to semi-maturity and could extract a few drops of insect liquid, and now collecting a jar of insect liquid is not a simple matter.

Although there is no evidence that insect fluid is attractive to giant insects, the situation that Ye Han encountered today is the best illustration.

The giant insect is not attracted by the poisonous gas, so it must run over and send it to death, right?

Ye Han figured out the joints and immediately contacted the airport: "Thunderbolt calls the command center, please answer if you receive it!" ”

"Command received, thunderbolt, please speak!"

Ye Han explained the situation near the chemical plant and asked, "How is the situation at the airport?" ”

"The onslaught of the giant worms has eased."

"The poison gas is spreading, and I suggest that the people near the chemical plant be evacuated immediately, as soon as possible." Ye Han suggested.

Although he could not see the area where the poisonous gas spread, he could judge the direction and boundary of the poisonous gas by the location of the death of the giant worm.

In the short period of time, the poison gas has spread outward for at least 30 meters.

"Roger, we'll consider your suggestion carefully." Commander Yu's voice appeared on the radio.

"What are you thinking about at this time? If you don't withdraw, it's too late! Ye Han said urgently.

Commander Yu cautiously asked, "How long do you think the poison gas can last?" ”

"I don't know, I don't see any signs of dissipation." Ye Han said.

"Okay, I'll arrange it right away, and you can withdraw it as soon as possible." Commander Yu said.

"I can't leave yet, there are more than 60 people in the office building." Ye Han said, "Can you find a batch of gas masks?" ”

"There are gas masks at the airport, but judging from the information you provided, the poisonous gas from the chemical plant should be sarin, which can be poisoned if it gets on the skin, and the gas mask is useless." Commander Yu said.

"What about the three-defense military vehicles? Can you find me a few military vehicles with three defenses? Ye Han asked again.

"There are indeed three-defense military vehicles, but have you thought about it, the concentration of poison gas in the chemical plant is so large, and the people in the building will have to be smoked by the poison gas if they dare to go out, even if I give you the car, how do you send people to the car? They continued to hide in the building, waiting for the gas to dissipate and then come out, with a better chance of survival. Commander Yu said.

"Okay, I see." Ye Han cut off the communication, "Five companies!" ”

"Roger!"

"Jian Yushu, I'm leaving, it's full of poisonous gas outside, you can't leave the office building for the time being, you take someone to find a way to seal the doors and windows, and wait for support!"

Jian Yushu gritted his teeth and spit out a word: "Yes!" ”

Ye Han sighed, and a communication was sent back to the Dynamic Decoration Institute: "Dean, did you receive a mission notice in the hospital?" ”

Qu Jiang was surprised: "You kid is very well-informed, the pianist just set off with a battalion." ”

"One battalion at a time?" Ye Han couldn't help but be shocked.

The combat effectiveness of the moving infantry far exceeds that of the traditional infantry, generally speaking, only one squad for ordinary tasks is enough, two squads for troublesome tasks, and a platoon is pitifully few.

Qu Jiang said: "The situation is even worse than expected, and now the giant insects that have entered the sand source can only be regarded as the vanguard force. ”

Ye Han gasped: "Where did so many giant insects come from?" ”

"I don't know the specific situation, I only know that these giant insects come from the grasslands north of the sand source, and they are likely to be swarms that have crossed the border." Qu Jiang said.

"Cross-border swarm again?" Ye Han is angry and doesn't fight anywhere.

Shayuan is located in the middle of the northern border, and about 100 kilometers to the north is the border, which is a semi-desert area on both sides of the border, lacking the basis for large-scale breeding of insect swarms, and the possibility of large insect swarms is extremely low.

But a few hundred kilometers further north is Siberia, which is the most likely place in the world to have a large number of insect colonies, with a large area of sparse population and a large number of plant and animal resources to support insect colonies.

Last year, there were giant locusts, and this year there were giant insects from the source of sand, to what extent is Lao Maozi going to be pitted?

Qu Jiang said again: "There is only so much information at present, and there is a lot of unconfirmed speculation, the soldiers will block the water and cover the earth, and there is no good way in the northern capital, let's take one step at a time." ”

"Understood, tell the pianist, and let him contact me when I get to Shayuan." Ye Han said.

"No problem." Qu Jiang agreed.

Cutting off communications, Ye Han took off his armored rifle, strode out of the chemical plant, and walked in the direction of the airport.

Dozens of meters away was the insect swarm that came and went, Ye Han didn't plan to fight the insect swarm head-on, picked a direction with fewer insects to go around, and soon arrived at the edge of the poisonous gas.

The way to judge whether to reach the edge is very simple, there are several giant insects standing in front of Ye Han, they want to rush towards Ye Han but they can't control the insect legs, and finally they fall down powerlessly.

Ye Han didn't even look at the giant insect that fell to the ground, and stepped over the dying giant insect and continued to move forward.
