"That's right, so we initially planned to destroy those eggs with gasoline." Natasha said, "If you like wet creatures, you must be afraid of flames."

"This idea is right, but if you like moisture, you may not necessarily need to keep your body moist at all times." Bai Youwei thought for a while and began to climb ahead of the ventilation duct, "Come with me."

The people behind were stunned, "Where are you going?"

"Go to find Yuri." Bai Youwei climbed to the fork of the ventilation duct, looked around and tried to distinguish the location, "...I thought of an idea, which is very suitable for dealing with those little monsters."

She turned a corner and continued to climb forward, regardless of whether the people behind her were following or not.

Natasha was separated from her two people, and she wanted to come up and ask clearly, but she couldn't get close to her, so she could only ask in a hurry from behind: "What's the idea?"

Bai Youwei crawled in front and said, "These monsters called alien species look quite like insects. Do you know how insects breathe?"

Ada: "Don't you?"

Bai Youwei paused, twitched the corner of her mouth and replied: "Some insects breathe on the valve and trachea, such as cockroaches, ants, locusts... There is a row of round holes on both sides of their abdomen, which is equivalent to human nostrils. Some insects breathe on their gills, such as dragonfly larvae and ephemerals."

"The alien species do not live underwater, so they should not rely on their gill breathing." Shen Mo said, "The possibility of valve breathing is greater."

"Yeah." Bai Youwei nodded her head gently, "They look like arthropod insects. Generally, arthropod insects breathe through valve ventricular pores, but it's strange that these insects usually don't make themselves sticky."

Ada also turned around and muttered, "Yes, my body is wet, and the air holes will definitely be blocked. How can I breathe?"

"There is another way of breathing..." Bai Youwei said, "The most typical example of body wall breathing is earthworms."

Natasha was surprised: "Earthworm?"

The alien species looks like a cockroach when crawling and lizard when standing upright. It is really hard to associate with soft creatures like earthworms.

Bai Youwei said: "Although it looks different, the habit of secreting mucus is quite similar. The earthworm's skin is rich in capillaries, and oxygen will first dissolve in the mucus on the body surface, then penetrate into the body wall, and then into the capillaries on the body wall, so it needs to continuously secrete mucus to keep the body moist. In other words, without mucus, the earthworm will die."

After hearing this, Natasha suddenly realized. After thinking about it for a while, she felt more and more unwilling. She sighed: "If there was still gasoline, just burn them to death!"

Even if it cannot be burned to death, the dry environment will definitely make them in great pain.

"I can still find a way to get a few buckets of gasoline, but this situation is not suitable for use..." Bai Youwei said slowly in front of her, calming down, "If it burns, the smoke will definitely enter the ventilation duct and we will be smoked to death."

Natasha: "Then... let's not ignite the fire first, wait until we leave the ventilation duct before ignition?"

"No need to be so troublesome." Bai Youwei stopped. At this moment, right below her, the tool room where Yuri was.

She tapped the partition twice and shouted in a low voice: "Yuri~"

Yuri had heard their movements and asked, "How is the situation outside?"

"At least 80% of the hatch, there are quite a lot of them anyway."

Bai Youwei moved forward and left a free position so that Shen Mo could come over and pry open the mesh partition of the vent.

Yuri said with a serious expression: "If it is 80%, our bullets will definitely not be enough. There is still explosives, but we must consider it carefully. Not only do we need to find a way to concentrate those alien species, but we must also lead them to a suitable location for explosion..."

"No need..." Bai Youwei stretched out a small hand from the pried vent and waved it to Yuri, "Put the toilet cleaner on the shelf behind you... Yes, that's the big bottle, hand me it."
