"Why didn't you save the injured guy this time?" Yan Shenshi asked curiously.

"It's not that you can't save it, it's that you can't save it at all, if you throw it down, you can at least delay it for a little longer!"

"Cut, you still did the thing you hated the most after all, and later...

"Can you stop talking?"

Chen Xunyi was quite disgusted that Yan Shenshi was rambling about what he had just done, he was just forced to do so, besides, the soldier was no longer breathing, and his neck was sucked by polydonts, so it was basically certain that the soldier was going to die soon.

And Yan Shenshi is now constantly holding this behavior to talk about him, which makes him extremely disgusted!

"Okay, let's not talk about it! When the hell are you going to light the fire! Yan Shenshi asked.

Chen Xunyi approached the outer fence and cautiously poked his head out, he was worried that he would be suddenly attacked by this multi-toothed worm, the oil drum was still bubbling out, although the number of multi-toothed worms on it was not much, but some had begun to leave the oil drum.

"It's coming! Soon! ”

Abel was also shouting, "When is it going to be?" ”

Some of the soldiers of the defense force had already turned their eyes to him.

"Hey! Doctor! Can't you light it yet? Oleph's mood had reached a point of considerable impatience, and his voice had become louder.

Chen Xunyi's eyes stared at the oil drum under the Great Wall of the border, "Wait a minute! ”

"Still waiting?" There are constantly people complaining, which makes Chen Xunyi's heart fluctuate slightly, he is thinking about whether he must wait until that moment, maybe the time is ripe, you can try!

But he was still very worried, if it didn't work out, it would be difficult!

His heart was entangled, the soldiers of the defense team were trying to drive away the multi-toothed insects, and his eyes were always fixed on the oil barrels and the walls of the Great Wall on the border, now? Or wait!

After a while, Yan Shenshi also joined the ranks of the expulsion!

Damn! The pressure in his heart has reached its peak at the moment, but he still can't release it, what if this is the best time? Missed ...

He grabbed the outer fence hard, the whole person was in extreme anxiety, and he kept shouting in his heart, now! Or wait! Now it's better to wait!

The pressure broke through Chen Xunyi's last line of defense, and he was ready to shout loudly to ignite the fire.

Suddenly, he saw the mouthparts of several multi-toothed insects on the wall sticking out.

"It's coming!" When Chen Xunyi saw the scene in front of him, his heart suddenly began to cheer up, he held his breath and stared at more and more insects stretching out his mouthparts.

"Aren't you alright?" Yan Shenshi frowned and shouted loudly.

"Wait a minute! Soon! Here they go! ”

When the multi-toothed worm on the oil drum stretched out its mouthparts, Chen Xunyi held the hand of the railing and squeezed it hard, "Ignite!" ”

The torches that had been prepared were thrown out of the soldier's hands and fell straight towards the area where the oil drum was.

As soon as the torch touched the oil drum, the flames immediately burst out from the ground, and thick black smoke continued to resound and drift into the sky.

The firelight lit up the entire night sky, leaving an orange glow on everyone's faces.

"Quick! Put away the lampholder of the spotlight! Chen Xunyi shouted loudly, "After making sure that most of the insects are in flames, immediately retreat!" ”

He took the lead in retreating to a position more than twenty meters away from the outer hurdle.

One after another, some soldiers pulled the lampholder back, and the other soldiers had already retreated to the place where Chen Xunyi was.

Yan Shenshi and Olef and the others also retreated.

"What's next?" Olev asked, "Flamethrowers can't kill them, do you think gasoline can kill them?" ”

"Yes! I'm pretty sure! Chen Xunyi squatted down, "Squat as much as possible, or lie down to hide, there will be a big fireworks show waiting for us in a while." ”

"Fireworks?"

Everyone squatted down and waited quietly, some people couldn't wait, and wanted to go up to have a look, but were scolded back by Chen Xunyi.

It's terrible! Chen Xunyi thought to himself, this kind of explosion could happen at any time!

The crackling sound came slowly, and then it got louder and louder, resounding throughout the sky, and the fire suddenly weakened.

"Gone?" Olef looked at the fire that was about to disappear and shouted suspiciously.

Boom! A violent sound sounded from the border Great Wall, and the surging firelight rushed out from under the outer fence and emerged more than ten meters inside the outer fence.

A huge burst of energy burst out, and the strong shock wave formed hit everyone, and after a heat wave, a tingling pain was felt on the faces of those present.

A few who were not lying on their stomachs were knocked to the ground by the shock wave.

Chen Xunyi wiped his face on his arm, and he kept slapping his body, removing the fine particles from the explosion.

"What's going on?" Olef asked curiously, his face seemingly full of question marks.

A soldier had already run to the outer fence, and the soldier shouted excitedly, "The insects are gone!" There is no trace on the Great Wall of the Border! ”

"I don't have time to explain! I'm going to work on the pipes tomorrow! Chen Xunyi raised his hand, said hello and walked to the military truck.

"Hey! You don't explain clearly? Yabel was also quite curious at the moment, and there was no longer the long-winded appearance just now.

"Let's talk about it when you have time!" Chen Xunyi walked away without looking back, he climbed into the military truck, sat there, leaned on the railing, and was fine! It worked, otherwise, I don't even know what to do!

He patted his chest lightly and let out a long breath

"You're so appetizing!" Yan Shenshi and the pioneer soldiers who came with him got into the back compartment of the military truck.

"I really don't have time to explain!"

"So there's time now?" Yan Shenshi asked, and he shouted to the driver in front of him, "Autopsy!" ”

Chen Xunyi leaned on the railing and turned his gaze to the outside of the Great Wall on the border, "You are also curious?" ”

"Of course!"

"When I dissected it, I found that the body and abdomen of this polydont were covered with a layer of such shells!" Chen Xunyi took out a shell from his pocket and put it in front of his eyes.

"This kind of shell, maybe that's why they're not afraid of flamethrowers!"

"Huh! I'm wondering about gasoline. ”

"I smelled a smell around the body of this bug, which was somewhat similar to gasoline, and after cutting the mouthparts of the worm similar to the straw, I found that there was the same smell in it, but not in the rest of the body, so I deduced that the mouthparts could radiate this smell around, similar to something like pheromones."

"So you think these bugs are going to smoke gas? Since this smell is carried by them, it is rare for any creature to ingest it! ”

Chen Xunyi looked at Yan Shenshi with a surprised gaze. ：，，，
