The innkeeper laughed and didn't answer Lin Fan's question, he didn't expect that Lin Fan would choose to come to this secret room to ask him these questions after solving the three of them.

It is not difficult to imagine that if Lin Fan had that strength, he would not communicate with himself with this attitude now, and he would definitely force himself to ask.

"I have no ill will towards you, as for the news of deliberately releasing that colorful glass fruit, it is just for a guess in my own heart."

"But what this guess is, I can't tell you until you find a way out of the secret realm."

After saying these two words, the figure of the innkeeper gradually disappeared into the secret room, and Lin Fan knew that this was because the innkeeper was unwilling to say anything more on this issue.

Right now, there was no reason for this Maple City to continue staying, and Lin Fan didn't have so much time to waste here, he had to go down as soon as possible, if he could directly find a way to leave the secret realm, it would naturally be the best.

But if you can't find it, find a place where the speed of time is 10 to 1.

Without continuing to dwell on the innkeeper's body, Lin Fan turned into a streamer and leaped towards the depths of the secret realm.

This time, he used the cultivation of the Immortal Realm to move downward, and in the past, it took several days to walk to see a city, but now it can be said that he can see one in the blink of an eye.

But until now, Sima Feng hadn't seen any city that was the one she remembered.

On the way to the depths, Lin Fan told the World Tree where they were now, as well as the things that were similar to insects they encountered when they entered the secret realm, and he wanted to ask the World Tree if he knew the origin of those insects.

What Lin Fan didn't expect was that the World Tree really knew something.

Those bugs are called soul eaters, and as the name suggests, they live by devouring spiritual power, and if they don't have spiritual power for them to devour for a long time, then they will devour their companions until there is only one left in their group.

The remaining worm will not leave its place, but will adopt a method similar to dormancy to seal itself until it has spiritual power for it to devour.

"This kind of soul devouring insect divides extremely fast, as long as there is enough spiritual power as an offering, they can divide infinitely, and even occupy the whole world where they are located."

Hearing the World Tree's description of the Spirit Devouring Insect, even if Lin Fan was a powerhouse in the Immortal Realm, he couldn't help but shudder, fortunately, this Spirit Devouring Insect was only devouring spiritual power, if even flesh and blood were devoured, then wouldn't Great Xia be finally occupied by the Spirit Devouring Worm.

Next, the World Tree said another sentence that made Lin Fan's jaw drop.

"In this world, there are not only soul devouring insects, but also immortal devouring insects, that is, insects that can devour immortal power."

"Just like the relationship between immortals and cultivators, these two insects are also mortal enemies of each other, and when they meet, one of them will be completely destroyed, or both will be destroyed, and there has never been a symbiosis."

Immortal eater?

Then if you can get an immortal devouring worm, won't you be able to get rid of all the immortals in Great Xia together?

This point, the World Tree did not refute, theoretically it is true, no matter how high your cultivation is, if you encounter a Soul Eater, you can only escape, or let the Soul Eater suck in your spiritual power, but your life will not be in danger.

Similarly, even if the Immortal Emperor came, it couldn't carry a small Immortal Devouring Insect, and it could also absorb the immortal power on the Immortal Emperor's body.

This is like an elephant and a mouse, although it seems that the mouse is the weakest existence, but it can sanction the elephant, the only difference is that whether it is a soul eater or an immortal eater, they have no natural enemies.

But the way to contain them is also very simple, drain all the spiritual power or immortal power in the place where they are located, and they will kill each other until there is only one left.

And because they don't leave their location, although these Spirit Devourers are strong, they are not regarded as a scourge by cultivators.

"Senior, is there any way to raise this soul devouring insect?"

After learning about the characteristics of the Spirit Eater Insect, Lin Fan's heart had already started to think carefully, since this Spirit Devouring Insect was so strong, if he could raise one and bring it back to Great Xia, then what else would he worry about.

No matter who comes, as long as the Soul Eater is released, it won't be long before that person will definitely be sucked by the Spirit Eater and become an ordinary person.

Thinking of this, Lin Fan couldn't help laughing, who would have thought that a small soul devouring insect would have such a wonderful use.

However, the World Tree gave Lin Fan a blow to the head, not to mention raising the Spirit Devouring Worm, even if it was close to the Spirit Devouring Worm, although the Spirit Devouring Worm would not leave the place where it was, there was one thing it didn't say accurately just now.

No one knows how big the place that the Spirit Devourer has planned for itself is, maybe only a palm-sized place, but maybe it is a vast range of thousands of miles, this point, no one can judge at all.

"Do you know where the Immortal Eater came about?"

When the World Tree asked this question, there was a kind of amusement in its tone, but there was also a kind of admiration, which made people wonder whether it was trying to express emotion or something.

"When the Soul Eater begins to split, there is a 1 in 10 million chance that it will be able to split an Immortal Eater."

This Immortal Devouring Worm could actually be split by the Soul Devouring Worm?

When the World Tree said this, it really surprised Lin Fan, but soon, he realized that something was wrong.

Since the Soul Eater Worm split into the Immortal Eater, they wouldn't attack the Immortal Eater swarm?

Can the Immortal Eater survive?

And this is where the World Tree sighs, at the beginning, the Immortal Eater is no different from the Soul Eater, until it actively flies out of the group of Soul Eaters, it will find a foothold and wait for the immortal power to be sucked by itself.

"Do you understand what I mean?"

The World Tree told Lin Fan so many things about the Spirit Devouring Worm and the Immortal Devouring Worm, not to satisfy Lin Fan's curiosity, but to tell him something cryptically.

It's just that before Lin Fan could think carefully about what the World Tree said just now, Sima Feng suddenly exclaimed.

"There, there, that's the city I'm talking about!"

Not far in front of Lin Fan and them, there was a magnificent city, the height of the city wall alone was more than three times higher than that of Feng City, and on the city wall at the top of the city gate, there was a broken statue.

It is not difficult to see that this is a statue of a cultivator who used to be a cultivator, and it should be a cultivator from before this world as the innkeeper said.

There was excitement in Lin Fan's eyes, and he landed not far from the city, he didn't know how many cities he had walked through, but he knew that there were quite a few, at least no less than a dozen.

"Sima Feng, before you people from the Demon Capital entered the secret realm, they would come to this city?"

Sima Feng nodded, she didn't know about the other families.

But their Sima family is here.
