At this time, the sinkhole was completely dark.

The three of them rested for a while, and then returned to the Ten Thousand Snakes Cave along the same path.

Master Wu'an took out an oil lamp, lit it, and covered it with a green lampshade. It's a lot darker, but from a distance it looks like a firefly.

In the Ten Thousand Snakes Cave, although the tallest stone pillar has been destroyed by Xiao Yao, the remaining stone pillars are still there, densely crawling with snakes again, and the two-striped black snake that was cut off by Xiao Yao has no bones.

The three of them didn't dare to get too close, and walked along the perimeter of the stone pillar.

Master Wu'an took out a bamboo tube and released some earthworm-like Gu worms from inside. The Gu worms began to burrow in the nearby soil, but not in the direction of the stone pillar, but in the direction of the center of the sinkhole.

The three immediately followed. These carrion Gu crawled for nearly three quarters of an hour before they began to stop in one place and spin around.

Uan immediately instructed Pan Li to dig through the soil with a scimitar, digging to a depth of about a foot, revealing some black bones in the soil.

The bones looked like they had been buried for a long time, and they were rotting badly. But there were a lot of black beetles crawling on top of the rotten bones.

"It seems that these are the bones of those divine beasts, but I don't know if there will be other places else." Pan Li said.

"There will definitely be. We need to keep looking. The beetles on these rotten bones eat the rotten bones, and they will be infected by the Gu poison in the remaining zài rotten bones. These beetles were then eaten by other snakes and scorpions, and the Gu poison first grew in the bodies of these beetles, and then continued to grow in the bodies of the organisms that ate them. ”

"But these Gu poisons are remnants after all, and even if they infect other animals, they won't survive for long. It's not enough to make Gu worms advanced at all. However, the Gu worms that were radicalized by the blood Gu were different, they could absorb these remnant Gu poisons, so those high-level Gu worms appeared. Master Wu'an explained.

"And what do we do with these dug bones?" Xiao Yao asked.

"It could have been burned with fire, but we can't light it here, and we can't touch the bones to prevent poisoning, so we can only melt them all with bone powder."

After Master Wu'an finished speaking, he took out a small vial from the package and poured some red powder from the bottle. The powder was poured on the bones, and immediately emitted a foul and pungent odor, and a lot of bubbles bubbled. Then I saw the rotten bones slowly melt.

Master Wu'an once again used the carrion Gu to carefully search within a radius of several miles, but did not find any traces of the bones of the divine beast, so he left with Xiao Yao and Pan Li.

"According to the records left behind, when the last Great Witch God died, there were still five divine beasts here. The great witch god could not bear to kill them, so he continued to keep them in this den. The place we just went to should only be the bones of one of the mythical beasts. It means that there are still four places where the bones of the divine beasts are buried, or four living divine beasts. There are still a few living divine beasts, it is not yet certain. Master Wu'an said as he walked.

"We continue to search in this beast cave, since we haven't found any traces left by the activities of the divine beasts during the day, it means that there are no more divine beasts in this dragon pool, I will send some more carrion corpse Gu, and search carefully in this dragon pool for the last time, if there is still none, we will go to other places to look for it."

Master Wu'an pondered.

"The two of us are the master's protectors, and the master can send Gu worms to look around." General Panli and Xiao Yao glanced at each other and said immediately.

So Xiao Yao and Pan Li were on the left and on the right, protecting both sides of Master Wu'an. Wu An took out a few bamboo tubes again and released five carrion Gu, and the Gu worms immediately crawled in different directions.

"We just need to wait here quietly, if the bones are not found, these Gu worms will come back in half an hour, if the bones are found, they will stay at the bones, I just need to put another carrion Gu, and then follow it to find the exact location." Master Wu'an explained to the two.

Since there was no need for the three of them to search for themselves, the three of them began to slowly observe the movements around them.

The dens of the beasts in the darkness were eerily quiet, with the occasional bird flying by in the night.

Half an hour is particularly torturous for the three of them at this moment.

Within a few minutes, Xiao Yao felt that the night in this sinkhole was very abnormal. With his own perception, he realized that the birds that occasionally flew by did not want to hunt, but seemed to be frightened and fled away.

Xiao Yao secretly carried up the getaway, concentrating his eyes and carefully sweeping around inch by inch.

Sure enough, the source of the anomaly was found!

At this time, Master Wu'an and Pan Li also noticed.

Dense crowds of ants began to gather in the vicinity of the three of them, and at first there were only a few hundred, lying on the ground unnoticed.

Soon, thousands of ants emerged around the three of them, all of them gathered in a small area, and then headed in a specific direction, crawling to the place where the three had just dug up the bones of the divine beast.

Countless ants kept crawling in the direction of digging up the bones, followed by more ants, and then followed.

What surprised the three of them the most was that not only were there so many of them, but that the rest of the insects had fled when they spotted them.

The three of them saw with their own eyes that some insects that could not be avoided were directly swarmed by these ants, and the bones disappeared in an instant.

Xiao Yao heard earlier that there is an ant in the forest in the south that sees what it eats, and he doesn't know if it's these in front of him.

Master Wu'an deserves to be a professional in this area. Immediately show its excellent professionalism and skills.

After carefully observing the ants, he tried to sprinkle some cinnabar in the direction they were heading, only to see that the ants immediately turned in a different direction, bypassing the cinnabar and continuing to crawl towards the place where the bones were buried.

Seeing this, Master Wu'an immediately pulled the two of them out of the way of the ant, and said to the two of them solemnly: "Things are even worse than I imagined. It seems that these ants have been infected with Gu poison, and their queen ant has been infected with Gu poison, and the rate of ant reproduction is many times faster than that of animals, so although many ants die because of Gu poison, there will still be many ants infected with Gu poison who survive, and they pass the Gu poison to the queen ant. Therefore, the newly-born ants in this anthill will be infected with Gu poison. ”

"Then what will happen if these ants can't find the bones of those divine beasts now?" Xiao Yao asked puzzled.

"This queen ant will continue to excrete the Gu poison from its body when it lays eggs, but the growth rate of Gu poison in its body cannot keep up with the speed at which it lays eggs, so it needs to keep eating the bones containing Gu poison. If you can't find a source of Gu poison to replenish the Gu poison lost in the queen's body, the queen ant will either die quickly, or the ants in this anthill will start refining Gu! Master Wuan said.

"What is Gu Refining? Is this the same as the Ten Thousand Snake Cave? Xiao Yao asked.

"Gu refining is the way Gu worms are raised, and the general Gu worm breeding is made with blood, that is, Gu worms bite and devour each other. The ants in this anthill are the same, they will bite each other and devour each other, and the ants infected with Gu poison will be able to gather more Gu poison from other ants, so that they will continue to evolve. ”

Master Wu'an said with a solemn face.

"Will there be a scene similar to the Ten Thousand Snakes Cave?" Xiao Yao asked.

"Ants are social insects, different from the common five poisons, this kind of social ants are generally difficult to raise as Gu worms, because raising them requires a lot of blood food to stimulate them to enter the Gu refining stage. Moreover, they themselves are very toxic, and even if they are refined, they will not be of special use. The snakes in the Ten Thousand Snake Cave rely on snake venom to continuously gather, thereby increasing the level of Gu worms, but these ants themselves are not poisonous, no matter how much they devour them, Gu worms with poisonous marks will not appear. ”

"It's just different now." Master Wu'an sighed softly and said.

"Is it because they've already been infected with the Gu poison here, so they'll start evolving soon?" Xiao Yao asked Master Wu'an based on his own inference.

"Not bad. And I also want to understand why there is a Ten Thousand Snakes Cave here. Master Wu'an nodded and continued.

"Why, could it be related to these ants?" Pan Li asked on the side.

"In fact, the so-called Ten Thousand Snake Cave is that different kinds of snakes gather at one time, and they are stimulated by the blood Gu and devour each other, so that the venom fuses with each other. Snake venom itself is one of the main sources of Gu venom, so the necessary condition for the formation of the Ten Thousand Snake Cave is that many snakes gather together. But under natural conditions, these snakes have to hunt everywhere, how can they gather together? So it is almost impossible to survive in the cave of ten thousand snakes under natural conditions, unless these snakes have to gather together! Master Wu'an said affirmatively.

"Master, do you mean that these snakes gather on those stone pillars to hide from what scares them?" Xiao Yao asked.

"Yes, and it's something that hides and crawls on the ground. As you may have noticed, the ground is unusually quiet at night, and it's hard to see reptiles on the ground. Uan said.

"I found this, what does that mean?" Xiao Yao asked.

It means that this ant is most likely not one nest, but many nests! And we're just seeing one of those litters now. So later, it's very likely that there will be these ants everywhere."

Before Master Wu'an's words fell, the three of them noticed the abnormality again.

A rustling sound began to appear in the distance, and the entire ground in the distance was covered in black. When you look at it, it looks like it's been smeared with black paint.

There are so many ants that I don't know how many there are.

"Hurry up the tree." Master Wu'an hurriedly shouted to the two. As he spoke, he climbed up to a tall maple tree next to him.

Xiao Yao and Pan Li immediately realized that the situation was not good, and in a flash, they jumped to a nearby big tree.
