He had expected that there might be mutant spiders who were lucky not to be drenched by gasoline, but he felt that even so, a large amount of toxic gas and temperature were enough to turn them into a pile of corpses, just the difference between scorched and non scorched.

Zhang Mu had an idea in his mind. He bypassed the mutant wolf dog, jumped down along the edge of the pit, slid down the black and yellow mixed soil to the bottom layer, and followed the dog claw traces of the mutant wolf dog. Zhang Mu came to a place, which had been planed by the wolf dog with its claws.

Now Zhang Mu finally knows why so many mutant spiders can escape from the sky. This place should be connected with a sewer of the abandoned factory. Although it is blocked, the environment here is extremely humid. In addition, it is a few meters deep from the ground. Even if the fire spreads to the thin and humid air, it will be extinguished slowly.

There are small holes in the ground near here, which should be drilled by the mutant spider in a hurry. The mutant wolf dog directly planed and enlarged one of them with the power of its own soil elements.

Zhang Mu slowly walked in along the dark hole, took out the flashlight in the era merchant ring, looked up and down, and wanted to see the situation inside. He didn't dare to use an open fire, for fear that there was something special in the air here.

The cave smells bad, and it's very humid. It's so stuffy that people's chest is uncomfortable. Fortunately, Zhang Mu's body has strong adaptability and hasn't reached the point of special discomfort.

He came to the place where the mutant wolf dog arrived, because there was no paw print in front of him. He must have been impatient to run up and ask Zhang Mu for credit as soon as he found the situation.

There is indeed a pile of bodies shed by mutant spiders on the ground, and the number is right as the mutant wolf dog said before. There are hundreds of them, densely piled in a corner.

Suddenly, Zhang Mu flashed his flashlight and found that the body in one place was very different from what he had just seen.

He walked slowly over, squatted down, picked up a flashlight, looked at it, and suddenly realized.

The corpse in this corner is not the shell, but the corpse of a real mutant spider, but the flesh and blood have dried up, the parts of the body are scattered, and there are few of the eight spider legs intact.

The number of these bodies is probably hundreds, which is only a lot more than those bodies.

Zhang Mu vaguely guessed the truth of the matter. I'm afraid there must be thousands of mutant spiders entering this cool cave, but those little spiders roasted by Zhang Mu's fire have lost their bodies and become the food of their own kind.

The mother of distress dedicated her body to her children. Although the energy contained in her body is extremely huge, even if the energy is huge, it is equally shared by five digit spiders. It is not enough for these spiders to complete their first evolution. Therefore, their ability to survive can make them focus on the same kind who took refuge with themselves, The hope of life is always left to the more capable people. This is the eternal law of nature. Even their own kind will not take into account when they face death.

"Unexpectedly, these little spiders quickly completed their first evolution in this way. It is estimated that only in this way can they escape against such a big fire. It's really a secret. There is a place where they can breathe for a moment. I knew it would be better to stay a little longer."

Zhang Mu seems a little regretful. The cave here has given those little spiders a chance of life. He has just observed that the place leading to the sewer at the end of the cave has been covered by a layer of sticky plants. Around the plant, you can see the body parts left by the mutated little spiders and a lot of entangled spider silk.

I'm afraid this plant is not a good stubble. For the mutant spiders who can only attack simply, it's like a natural graben that can't cross the past.

Those mutant spiders found that after breaking through the hopelessness here, they rushed out of the slightly weakened sea of fire by relying on their evolved shell and left here.

Zhang Mu's speculation is almost the same as the truth. These clues are enough for him to judge too much information.

Zhang Mu walked back along the way he came. When he got to the ground, his expression was a little heavy.

Just now, Yuan Rui, who was waiting for Zhang Mu to jump down without saying a word, came over with Haohao, stared at Zhang Mu, saw that he was intact, and asked, "uncle, what happened? I just saw you look so nervous. Is there any serious problem with the spider?"

Yuanrui probably guessed. Zhang Mu also felt it was not meaningful to hide from them, so he directly said, "a group of mutant spiders escaped here and survived after evolution."

"How could this happen? We almost died here in such a big fire. Can't we burn those demons?"

Yuanrui seemed a little unbelievable. The fire posture made by Zhang Mu was too big, which left a deep impression in her heart.

But at this time, Haohao's eyes seemed a little excited, "Uncle Zhang, does this mean that when I grow up, I can find these monsters and avenge my mother by myself."

Zhang Mu lost his smile. Haohao really interrupted his thought.

What he had to consider just now was whether to continue to pursue those mutant spiders.

But now he is faced with two problems. One is that the number is too large for a long time. Zhang Mu doesn't know whether they will take collective action if they have evolved once. In case they are scattered for such a long time, they will spend their energy fetching water in a bamboo basket. The other is that he has to hurry up to complete the era merchant task and open the authority of primary agents in advance.

Forget it, it's only a few hundred. Before tens of thousands, he panicked. Zhang Mu smiled and said to Haohao, "it's normal for these little things to go out and be eaten as snacks when the quantity is not enough. Even if there are really left, let Haohao solve it."

The excitement in Haohao's eyes flickered, because this time he had the hope of personal revenge and said, "let me grow up quickly."

Although it's fun to look at Haohao's excited and serious appearance, Zhang Mu still has an indelible sense of depression in his heart.

It seems that these mutant spiders may really have big problems in the future, otherwise my intuition won't give me this feeling.

Forget it, there's no way. Let's go step by step. There are more important things to do.

No more watching and staying, Zhang Mu and Yuanrui left the town immediately and continued to rush back to Luoyang.
