There are so many of these insects that they are everywhere in the air, and they are as tiny as a needle tip and are difficult to spot.

The air was foggy, and it seemed to be all because of these insects.

Could this be the real reason behind the demise of this ancient sect? For any living creature to exist, it needs a complete food chain. What do they rely on to survive?

Dole caught some insects and put them in his own special collection bottle, which he sealed completely.

The clone does not have the conditions for research here, so he has to go back to do research. This insect is too lethal, so he has to preserve it well. If he is not careful, it may become a place with no trace of human beings.

At this time, the old poisonous creature was also observing the surroundings. He did not take the matter of the poisonous insects seriously. Such things were too small and could be resisted with their own strength, as long as there were not too many of them. Looking around, the old poisonous creature said:

"Dole, according to the information I got, this is a complete sect. The front is where ordinary people and ordinary disciples live. We still have to go to the back. The warehouse, secret manuals, and materials are all on the mountain. But do you have any way to stop this thing? I only have some small tricks here, which can't stop it for too long. And the higher up you go, the denser the existence of this thing may be."

Dolai was stunned for a moment, "The higher it is, the greater the density of existence?" He sensed it carefully and found that there was no difference between above and below. If there was anything completely different, it might be the density of the environment and energy elements, classification!

He said slowly, "Don't be anxious. Let me think about it. This thing is not simple. My level 6 Xuanshi Bug has a hard time dealing with it. I'm afraid the purpose of its creation was not an accident, but intentional."

The old poison was stunned for a moment. He looked around and said in disbelief, "It was intentional. Who could deliberately trap an entire sect to death here? This involves the lives of thousands or even tens of thousands of people. This is too cruel."

Duolai curled his lips and said, "Maybe there is a grudge, or it could be the great elder who had a conflict with the sect. Anyway, although this thing is very active, it is not outside, which in itself sends a signal."

The magic circle can block people and large creatures, but it should not be able to block small things like this. However, there is nothing outside, including a gap as big as the gate, which is obviously abnormal.

There must be something different between the outside and the inside, which locked these little things tightly, so there is no danger of leakage.

What is the difference between outside and inside?

Dole thought about it carefully, and there were so many differences.

Air, humidity, oxygen content, barometric pressure, these could all be factors.

The environment of this unknown sect is almost the same as it was many years ago. The surrounding pavilions and towers have only shown signs of vicissitudes of time and are covered with a layer of dust, but the structure remains quite intact, and it looks like an old courtyard that has not been disturbed for decades.

Looking outside from here, you can see the sky outside. The thick fog seen from the outside looking in does not exist. At a glance, you can see the sky hundreds of kilometers away.

The environment here is much better than that down there. The air is fresh, and there are all kinds of tall trees, distributed in different places, embellishing this desolate world.

There was indeed nothing to see in the front. The two stayed there for a while but did not come up with any analysis results.

After attaching some of the mysterious corpse worms to the old poisonous creature to help him isolate some of the poisonous insects, Duolai and the other man began to move forward.

This was a completely dead world. Even the air was still here. It was so quiet around that there was not a sound at all. The two of them went up quickly and soon reached the middle yard.

There is a door here that separates the inside and outside. It looks like after climbing over this door, the inner courtyard should be inside.

The old poisonous creature was a little excited. What he wanted to do most now was to find the treasure house and see what good things were inside.

The front yard and the middle yard are both ordinary areas. Even if you can find some things here, they are used by ordinary people and ordinary disciples and are not very valuable. For high-level wizards like them, the higher-level things are more useful. There are a lot of low-level things outside, so what's the use of them.

To pass through the central courtyard, one has to pass through an isolation gate, but this time the isolation gate has been broken, revealing a tattered threshold.

When the two saw this, their hearts sank, as someone had gone in.

The two looked at each other, then walked straight through the door and headed inside.

The scene inside was a little different again. There was some fog in the air, and it felt wet. The density of those small insects increased again.

Duolai didn't feel anything, but the old poisonous creature's face changed and he retreated directly.

Some red spots soon appeared on his face, and he hurriedly took out some medicine and applied it on his face.

Dolai also felt at this time that there were more of those small insects here and they were more powerful. Even the black corpse worms were suffering unprecedented attacks.

This tiny bug can basically be said to be a slightly larger virus.

Now he has a question in his mind, who made this thing? This might be the culprit that directly destroyed the sect.

At this moment, Duolai glanced and saw the first corpse in the sect. It was at a corner at the end of the front corridor.

It was a pair of legs with only bones left, and the bones were completely black. Although the whole picture could not be seen, it was estimated that the front half was the same.

All the Xuan corpse worms in the body started moving at this time, trying their best to digest these small insects. However, there were too many small insects, so many that it was unimaginable. Almost every inch of the air contained tens of thousands of them.

How do these things survive? It's really strange.

Dole just took a look and then stepped back and returned to the middle courtyard.

At the backyard door, the old poisonous creature's face looked a little ugly. The power in his body continued to radiate. His face had regained its previous color and his skin had become smooth again, but his face was still very ugly.

Duolai glanced at the old poisonous creature and said, "This insect has a high magic resistance. Even if the protection is fully activated, it cannot completely defend against it. Otherwise, I will cover your entire body with the black corpse insect?"

After being here for so long, he has discovered that this insect is very powerful and can penetrate defenses with its tiny claws. If he were not in the form of an insect, he would have no better solution at this time.

The old poisonous creature had an extremely gloomy face. He had finally gotten in, but the situation inside was indeed like this. No wonder those who went out were all so silent and didn't speak. They probably couldn't say anything.

He didn't see any corpses along the way, but he could imagine that those who came in front must have taken the corpses away or hidden them to trick the people behind them.

If you don't get any benefits yourself, then others won't have an easy time either. This is the bad nature of human beings.

Duolai told him what he had just observed. The old poisonous creature said with a gloomy face, "That should be where the people outside went in and died. These little bugs are so ferocious, their toxicity and penetrating power are extremely strong, and there are so many of them that people feel terrified. No defense is useful."
