"Fire is useful, use fire!" Zeng Tao said excitedly immediately.
At this time, Li Wenxi's voice was heard from the main tree house.
"What's going on outside?"
She also heard the sound of insects gnawing at the trees, saw the trees constantly falling in the jungle, and leaned on the window and shouted towards this side.
"Bing!" Coco also called out to this side, "Bing bing bing!"
The meaning seemed to be telling him to go back quickly.
Xu Xin immediately shouted to the main tree house, "Wen Xi, tell them to turn off all the lights! No light is allowed in the tree house! There's something going on outside!"
"I see!"
Within five or six seconds, all the lights on the four floors of the tree house went out.
The area around the tree house immediately became dark, with only the torch that Xu Xin had inserted into the ground still burning and emitting light.
Suddenly, the flying insects became even crazier and rushed towards the torches in groups.
But there were so many insects flying towards the torch, and some even on the ground climbed up along the torch. In a moment, the torch was surrounded by the swarm of insects and extinguished.
However, many insects were burned to death and an unpleasant burnt smell filled the air.
Flames are very useful.
The insects, having lost their target, returned to the jungle and began to eat the trees.
"Let's set fire to the forest! Burn all those bugs to ashes!" Zeng Tao suggested.
"Are you crazy?" Lou Feier patted her head. "Do you want us all to die?"
“Don’t hit me on the head!” Zeng Tao slapped her hand away and said nonchalantly, “It’s not like we haven’t encountered forest fires before. Didn’t the jungle grow back the next day? We didn’t die.”
Jin Yue frowned slightly: "I think we shouldn't do this kind of thing unless it's absolutely necessary. Setting fire to the mountain is extremely harmful."
"Why not?" Zeng Tao pointed at the jungle. "If we don't burn it, the jungle will probably be eaten clean by the bugs. Once they have eaten the jungle, they will come and eat us! It's better to let the jungle sacrifice itself gloriously and perish together with the bugs!"
Zeng Tao's words do make some sense.
but…
It’s better not to do this.
"If we set fire to the mountain, how long do you think it will last?" Xu Xin turned his head and looked at Zeng Tao and asked.
"Well... although a jungle fire can burn for a long time, that's because it keeps spreading outward." Zeng Tao thought Xu Xin was afraid that the jungle would burn for a long time, so she argued, "The area around our tree house won't burn for long, right? Besides, the jungle fires in this world should also cover a large area, right?"
The rivers in the jungle are complex and the wildfire may only burn an area and will not affect many people.
After all, most of the people around them had already been on their side as explorers.
"Whether the spread will affect other people is not the point, but because it can't last long, we can't set fire to the jungle." Xu Xin shook his head. "The trees around the main tree house will burn out in a few hours at most. This batch of insects has been burned, but what about the next batch? What about tomorrow night? What if there is another swarm of insects tomorrow night?"
"This..." Zeng Tao was stunned by the question and murmured with her head down, "The jungle is gone, but there are still insects... And maybe the jungle can grow again..."
"You probably don't know how these bugs appeared?" Xu Xin asked.
The three girls all shook their heads: "Not sure."
The problem of insects still needs to be handled with caution.
It is indeed possible that this jungle will be eaten clean by these insects, but at their current speed, it is unlikely that they will finish it all in one night.
At least it would last three nights.
It’s better to keep it.
Xu Xin spoke up at this time: "Setting fire is indeed a solution, but there is no need to burn the forest. Let's light a few bonfires in the open space to test the effect. If it doesn't work... we can dig a circle of trenches and set fire to them."
The fire trench that was dug during the tree house defense battle had been filled in by him a long time ago. If he wanted to set a new fire, he would need to dig it again.
Let's try a campfire first.
Light a bonfire, and these insects will have the fire as their target, so they should not attack the tree house.
"That's a good idea! But what should we use to make a fire?"
"Mutated vines." Xu Xin said.
The mutated vines can burn much longer than wood, and one vine can burn for an entire night once and for all.
As explorers, they have no shortage of mutated vines.
After all, the juice of the mutant vines is used to make explosives, so they must have sufficient reserves of this stuff.
Before in the underground world, they, especially Wen Guixin, brought up a lot of mutated vines from underground.
And yesterday, the first day of the hot summer, while he and Li Wenxi were busy, others were not idle either.
The cold winter is over, and dangerous areas in the jungle appear again. Wen Guixin and her people are responsible for going to the dangerous areas to kill the vines.
Although she only operated for about an hour before returning due to the heat, her speed in clearing out monsters was enough to last them for a long time.
Xu Xin turned and looked at the women around him.
What should they do with their tree house now
Zeng Tao didn't care anymore, after all, her tree house was basically beyond saving.
The tree houses of Lou Feier and Jin Yue are both about a hundred meters away from the main tree house, very close to the lush jungle, and only a few meters away from the jungle.
Their tree house is likely to be the first to be attacked!
Although it may not necessarily be destroyed, it is still necessary to take precautions.
And there is Qin Fu.
Where did that guy go
The map instantly appeared in his mind, and then he saw a red dot about five or six hundred meters away from the main tree house, and it was slowly moving in a farther direction.
This guy has just recovered, what is he going to do now
Forget it, let’s deal with the area around the tree house first!
"You two, go to the tree house and pack up your things, and take all the valuables with you." Xu Xin turned to Lou Feier and Jin Yue and said.
Their tree house is too close to the jungle, so they should just let everyone come to their own tree house.
"I'll go help them!" Zeng Tao also followed them.
Xu Xin quickly returned to his tree house.
"What's going on outside?" Li Wenxi immediately came over and asked worriedly, "Why are those trees falling one after another?"
Xu Xin briefly explained the situation, and then said, "I need mutant vines to make bonfire materials!"
Most of the explorers' supplies are stored here with Li Wenxi, and Li Wenxi brought all those materials with him when he came this time.
"good!"
Lou Feier, Jin Yue and Zeng Tao had already finished cleaning up the dozens of dead mutant vines they had come down from the tree house. Together with Xu Xin, they quickly placed them in a circle about seventy to eighty meters around the tree house and then set them on fire!
The mutated vines are a very flammable material, so just roll them into a ball on the ground and light them on fire.
There were extremely bright flames burning on all sides of the tree house.
Suddenly, the swarms of insects in the jungle went crazy!
Countless flying insects and reptiles rushed towards the burning mutant vines and threw themselves into the fierce flames!
Then became part of the flame.
The flames of the mutated vines are much brighter and more intense than those of torches!
Even though the swarm of insects was surging, they were unable to put out the flames with their numbers. Just being stoked by the external flames, these tiny flying insects turned into ashes, using themselves as fuel, which made the flames even more intense!
The same goes for the reptiles on the ground. If they crawl into the flames, they will only serve as fuel, making the flames burn more vigorously!
The tree house was also illuminated, and the survivors in the tree house were basically lying on the windows looking out.
“Is this how you repel insects?”
"A whole circle of flames!"
"Oh my god, so many bugs are flying into the fire! Oh my god, they are so densely packed, so disgusting!"
"Why is this fire getting stronger and stronger?"
"The insects are using their bodies to add fuel to the flames."
"Go away, go away. Don't make a fuss. I told you, living with Brother Xin, what do you have to worry about?"
"Indeed, except for not being able to use my tree house to communicate with the outside world, this place is extremely comfortable!"
"Haha, it's so bright outside! It's just like daytime. There's no need to turn on the lights. Let's continue having fun!"
"Keep going, I'll definitely win the next one!"
This group of people is quite comfortable.
Of course, they are now equivalent to being locked in a tree house. They are enjoying themselves and not clamoring to go out, which actually saves Xu Xin a lot of trouble.
Looking at the raging flames in front of him that were very effective, Xu Xin nodded with satisfaction.
The flames produced by the burning of mutated vines are very stable, and there is basically no wind in the jungle now, so it will not affect the surrounding jungle and cause forest fires, and it can stably attract and kill insects.
However, there are still disadvantages.
Flames will significantly increase the temperature of the surrounding environment.
The temperature at night was originally only forty degrees, but now, under the influence of these mutated vine fires, the surrounding temperature is rising rapidly!
Moreover, the mutated vines are not ordinary wood. The temperature of the flames they produce when they burn is much higher than that of ordinary wood!
This means that even Xu Xin cannot get close to the area around the flames!
The temperature around the tree house, due to the scorching heat and the flames, directly exceeded the temperature at noon, breaking through 60 degrees and approaching 70 degrees!
At this temperature, you can fry eggs...
"It's so hot..." Zeng Tao complained weakly.
"This is the first time I feel so hot..." Lou Feier wiped the sweat from her forehead.
Although Jin Yue didn't say anything, her whole body was soaked.
Although they have mutant physiques, they still can't stand the high temperature of nearly 70 degrees.
In comparison, Xu Xin, who has high temperature resistance, is relatively at ease at this time.
"You guys go to my tree house first."
No matter how hot it is outside, it will not affect his tree house. After all, its constant temperature capability is still very strong.
This method can be used by other explorers!
The girls returned to the tree house and were pulled up by Li Wenxi, while Xu Xin continued to observe for a while.
No bug was interested in his tree house. Even the bugs in a large area around it gave up eating the trees and rushed towards the flames frantically.
It's safe for now.
Moreover, it has greatly slowed down the destruction of surrounding trees.
He immediately contacted Ji Chaoyang.
"... I had the same idea, but I didn't expect the effect to be so good." Ji Chaoyang was a little surprised that this method was so effective.
However, he had one more preparation method than Xu Xin.
"Xuefei is using herbs to make a potion to repel insects. I have been helping her. It should be successful soon."
Insect repellent
nice one!
"What materials do you need?" Xu Xin asked immediately.
"She has everything here, mugwort, oregano, mint... I don't really know much about them. She has a lot of these materials, so she doesn't need us to provide them, and we can't provide them. According to Xue Fei, this potion should have a strong insect repellent effect when sprayed on the body."
This is really good stuff!
Although the flying insects and crawling insects have not caused any harm to them yet, it does not mean that they will not attack them in the future.
It’s also good to have something to deworm himself so he can go outside!
After hanging up the call, he immediately returned to the tree house and contacted Ma Hongwei.
Ma Hongwei said that it would be better not to give up the heavy crossbow on his tree house and the things in the tree house, so he planned to do the same thing around his tree house.
Xu Xin just let him go.
He also contacted Qin Fu, who was outside doing something unknown.
Qin Fu is still very close to his tree house, and his watch can be used normally.
"What are you doing outside?" Xu Xin asked directly.
"Boss, I found something unusual around me!" Qin Fu's voice was muffled. He must have covered himself tightly. After all, he was in the jungle, and the flying insects were flying in groups. "I feel like I can find the source of these insects!"
"Oh?" Xu Xin's eyebrows relaxed immediately, "Are you sure?"
"I'm not sure, I just have this feeling. I'll contact you when I find something unusual, boss."
After hanging up the call, Xu Xin felt that this was handled quite well.
Everything went smoothly.
But now is not the time to rest.
because…
"Xu Xin, should I go back and light a few fires around my tree house?"
Li Wenxi said with some concern.
"I was planning to do that." Xu Xin nodded, "Your tree house must also be protected."
Her tree house is not a parasitic tree house. If her tree house is eaten, the other tree houses that are parasitic on her tree house will be destroyed.
A group of people will be displaced.
Not just her tree house, but everyone else’s.
Especially Qi Xuefei, Qin Yunlong and Qin Yunhu, there is no one there now!
"I'll go and help!" Lou Feier stood up.
Jin Yue and Zeng Tao also expressed their willingness to help.
At this temperature, they are the only ones who can move normally outside the tree house.
"Okay. Go help Wen Xi and Sister Xue Fei light the bonfire. I'll go check on the other explorers!"
"clear!"
"I know!"
The three girls went out immediately.
Xu Xin quickly contacted Ji Chaoyang and told him that they would light a bonfire around Qi Xuefei's tree house.
"Thank you." Qi Xuefei's voice came, "My mosquito repellent will be ready soon."
"It's up to you."
After hanging up the phone, Xu Xin immediately prepared to go out.
“Hmm…” Coco tugged at his trouser leg.
"What's wrong, Coco?" He looked down, "Is there any danger outside?"
"Hmm!" Coco nodded her little head.
"What danger? You mean those bugs?"
"Bing..." The little guy tilted his head, then shook it, "Bing."
What it means is, it's not clear.
But he still had to go out.
"Be careful!" Li Wenxi became a little worried when seeing Keke's attitude.
"Don't worry, the bugs nowadays don't attack people."
Xu Xin didn't waste any more time and immediately got down from the tree house and teleported to Wen Guixin's side.
As soon as he was teleported here, he saw several bonfires.
Although not as much as his, it has already been ignited.
Countless insects are flying towards the campfire!
"Why are you here?" Wen Guixin poked her head out of the window.
"It's okay, I just want to see how you solve it. I also use this method, as long as you can solve it."
"It's not my idea." Wen Guixin pointed inside the tree house and said, "It was their idea. Okay, I'm going to close the window. It's too hot outside!"
As she said this, she was about to close the window.
"I have something to tell you. Sister Xuefei will be able to make mosquito repellent soon."
"So strong?!" Wen Guixin stopped closing the window with a little surprise, but then shook her head, "It's only useful for people like you who can go out, right? It's not very useful to me. I don't want to go out. It's too hot."
She closed the window and ended the conversation.
Xu Xin set two more fires in the relatively open area here, and then came to Wang Lei.
Wang Lei's side has not been dealt with yet, but fortunately he knew to turn off the lights in the tree house.
"Brother Xin, are you here?"
Xu Xin immediately went up and told them the solution.
"I'll go back for a while!" Qin Yunlong, who lives with Wang Lei, immediately stood up, "Go and protect my tree house!"
The temperature at night was only around 40 degrees, so it was not a problem to stay outside for a short period of time, and Xu Xin did not stop them.
He came to find Zhao Xiaochuan again, and Zhao Xiaochuan was lighting a bonfire outside the house.
When asked, Qin Yunhu had already gone back.
It seems we are smarter here.
He immediately came over to Li Wenxi and took a look.
There were almost as many bonfires around him as there were on his side, and the temperatures were also incredibly high.
Fortunately, no one lives here now.
Back to his tree house, basically back with him.
"We have accomplished our mission!" Zeng Tao's face was red from being roasted. "It's so cool to watch those flying insects fly into the fire!"
"What a bunch of stupid bugs. It's a good thing they are stupid." Lou Feier sighed.
"Okay, let's go back."
The few of them returned to the tree house, and the protective measures for the night came to an end.
Sitting on the sofa, Xu Xin let out a long sigh.
"Finally it's done." Li Wenxi leaned beside him and said, "It should be fine tonight, right?"
"... There is still a problem." Xu Xin stroked Coco who was lying in his arms with one hand, and rubbed his temple with the other hand in distress.
The issue of insects should be considered to have come to an end for the time being.
When he came back, there were obviously fewer insects flying towards the flames.
It’s not that the insects no longer attract light, but that many of them have died, so the density of the insect swarm has become much smaller.
but…
The temperature of the bonfire affects tonight's plans.
His original plan tonight was to stay up all night to see if the temperature would rise abnormally, but now...
He had manually raised the temperature around him.
… What should I do
