Ye Han blinked, turned around and asked: "Xiao Yuan, do you think insects are afraid of smoke?"
Xiao Yuan was stunned at first, and then he was overjoyed: "I'm afraid, I must be afraid! If we light a few more fires, maybe we can smoke out all the bugs!"
Ye Han chuckled like a naughty child: "Why smoke it out? Next time we won't even enter the hole, we will put smoke outside the hole. If we find that one exit is blocked, we can't kill them!"
Giant insects evolved from insects, and their body shape has changed, but they are still essentially earth creatures and still need to breathe oxygen. Moreover, after the size of giant insects expands, their demand for oxygen is higher.
Although bugs can't cough, the effect of thick smoke is certainly not bad.
"What about this hole?"
"It's already come to this, let's continue." Ye Han said in pain.
He just remembered that there were countless larvae in the lake. The thick smoke could only scare away the adult worms, but there was nothing that could be done about the larvae in the water.
Of course, this problem is easy to solve. Just pour poison into the water to kill the lake worms.
The highly toxic poison will definitely cause large-scale pollution of underground lakes and entire water systems, but what is pollution compared to eliminating the threat of wolfworms?
This place is not too far from the border. If the underground water system is particularly large, the poison may spread into the country along with the water flow... Well, I'm afraid you have to ask experts in water conservancy or geography whether to invest or not.
The flames in the cave hall gradually extinguished, but the heat wave and thick smoke were still filling the inside and outside of the cave hall.
He raised his legs and stepped into the cave hall. The charred insects on the ground were all strange and strange. When he stepped on them, they broke like dry branches. When he crushed them hard, they were broken into slag.
Xiao Yuan said with emotion: "It's so fucking unthinkable to use artillery shells to deal with bugs. From now on I'll just use incendiary bombs."
"Why don't you just use the flamethrower?" Ye Han asked with a smile.
"That thing is too troublesome."
Flamethrowers use liquid fuel and cylinders are essential, while incendiary bombs use solid combustible agents. The latter is much more convenient than the former.
Ye Han smiled: "Don't talk nonsense, which way are you going?"
"This way!" Xiao Yuan pointed to a cave entrance.
"Leave a fire team to guard the hole, don't let the insects cut off the way back." Ye Han said and walked towards the target.
"Yes!" Xiao Yuan agreed, leaving a group behind and followed Ye Han a few steps behind.
Walking into the passage, Xiao Yuan said again: "The place was crowded with bugs just now. It's good now, not a single one can be seen. If I had known, why would I have bothered to do that? Couldn't I have just set a fire to solve everything?"
Although the open fire in the cave hall has been extinguished, the thick smoke will not dissipate for a while, and the insects can't hide, so how can they dare to come here?
"Let's talk about it next time... How far is this place from the hatchery?" Ye Han asked.
"The straight-line distance is four to five hundred meters, with a cave hall and two forks in the middle." Xiao Yuan said.
"Speed up and if you find any bugs again, live or dead, set a fire for me. Burn them as hard as you can."
There is water in the cave but there is no suitable combustible material. Burning insects to make smoke is a feasible solution.
"Then we will happily decide!" Xiao Yuan said.
The road under your feet fluctuates up and down, and from time to time you can see a small patch of thick smoke accumulating on the roof of the cave. After walking a certain distance, the road under your feet shows an obvious slope.
Thick smoke and hot air have the habit of traveling upwards. After the team began to descend, not only the visibility was greatly improved, but also the air quality was much better. Only halfway through the journey, the armor automatically released the alarm and reconnected to the outside air.
The good air meant that wolf bugs could appear at any time. Ye Han immediately ordered the team to be more vigilant, but the bugs did not appear as suddenly as he thought.
There were no bugs to cause trouble, and the team moved incredibly fast, successfully arriving at the hatchery in a short time.
To be cautious, Ye Han did not break into the hatchery immediately, but hid outside the cave entrance to observe the situation.
The hatchery is a large cave hall, with iconic stalagmites and pillars everywhere, but the ground, walls, and anywhere that can be placed are filled with densely packed insect eggs.
The oval, milky-white eggs are each about the size of a fist, and they actually look a bit cute.
Dozens of wolfworms were busy carrying eggs in the cave hall, looking very diligent.
Ye Han asked in a low voice: "Xiao Yuan, where did the insect eggs come from?"
"I don't know, I didn't bother to check."
"Remember those holes!" Ye Han pointed at several holes in the hatchery and said.
"Captain, should we continue moving forward?" Xiao Yuan asked quietly.
"It's necessary!" Ye Han said.
At first glance, the busy bugs seem to have no pattern, but if you look closely, you will find that their actions are very regular. For example, the bugs leaving the hatchery are all empty-handed, and the bugs entering the hatchery are holding eggs.
Arriving at the hatchery is already deep into the insect nest, but the holes where the insects enter and exit must lead to more important points in the insect nest!
The hatchery is important, but it is by no means irreplaceable. Only by blowing up the swarm's delivery room can it be possible to deal a fatal blow to the swarm.
Xiao Yuan said: "How can so many insects get away? Is it possible to set another fire?"
It is very easy to set a fire, and the thick smoke can drive away all the insects in the hatchery, but doing so will probably disturb the egg-laying female insects.
At the moment, no one knows how wolf worms lay eggs, but Xiao Yuan, like Ye Han, is convinced that there must be a queen specifically responsible for reproduction in the nest.
It may be one, or it may be a group. In short, the entire insect swarm is centered on a fertile female insect, just like the situation with ants.
The key to the problem is what the insect queen looks like and whether she has the ability to move!
Queens of different types of ants are also different. Some are bloated and unable to walk and must be looked after, fed and protected by worker ants. Some queens are just larger than ordinary ants, are agile and move quickly, and can run away when in danger.
If the composition of the wolf swarm is similar to the former, then setting a fire is no big deal; on the contrary, if it is similar to the latter, then setting a fire will only scare away the queen.
After scaring away the insects, it will be difficult to find them again.
Ye Han hesitated again and again, and finally gritted his teeth and gave up his previous idea: "If you don't want to leave, I'll put a nuclear bomb here and kill you!"
Finding the worm queen is indeed very attractive, but whether finding the worm queen or catching the worm queen, apart from proving the population structure of wolf worms, what is the use of it? Is it possible that Beidu can cultivate wolves like giant ants?
insect?
Xiao Yuan asked worriedly: "What if we didn't kill the queen and let them escape?"
"It doesn't matter." Ye Han said, "Three big firecrackers can destroy most of the cave. When the time comes, they will be short of food and clothing. I don't believe that the remaining bugs can survive until next spring. If it doesn't work, we can come back and bomb them again next spring.
