The giant worm opened its jaws wide open.

The huge mouth with sharp teeth that shone with cold light was five meters wide.

In the mouth, there are countless barbs, a dark red tongue, like a three-pointed blade!

Roar!

The barbs in the giant worm's mouth, the tongue vibrated and let out a loud roar.

This loud roar directly shook Cheng Mo's eardrums numb, and around him, the one hundred and eight streams of green smoke quickly condensed, and one hundred and eight nian beasts reappeared.

Only this time, the light emitted by the eyes of this nian beast was no longer cyan, but slightly red, fierce and terrifying.

Feeling the change in the aura around him, Cheng Mo knew that this was broken, and the originally cute and harmless little green worm had become this fierce and terrifying tooth worm!

Is this a pig and a tiger?

"Food...... Things!"

After the roar, the giant insect closed its sharp tooth and huge mouth, and its two small black eyes stared at Cheng Mo, and there was such a thought wave.

Cheng Mo was speechless, he pinched Xiao Lu between his fingers, shook it back and forth, and said:

"Are you sure you want to eat something like this hair? I'm afraid you can't even stuff between your teeth!"

Speaking of this, Cheng Mo's heart suddenly moved, such a creature seemed to have an impression in his memory.

This memory should be from the memory of Ye Ao, the senior brother of the Shenmu Sect, and there is a rumor about this world tree.

Legend has it that when the founding patriarch of the Shenmu Sect first saw this World Tree, he had communicated with this world's first tree! At that time, there were countless creatures living in this World Tree, and the most numerous were these insects, all of which survived by eating the bark and sap of the World Tree.

The World Tree was overwhelmed, and when he saw the ancestor of the Shenmu Sect, he invited him to help him remove the parasites on his body, and the ancestor of the Shenmu Sect readily agreed.

It was because of this that he was able to establish a sect on this World Tree, leaving a legacy for thousands of years.

There is such a rule in the ancestral teachings of the Shenmu Sect: Hundred years of Weishu, don't forget the original intention.

Cheng Mo thought of this, and then looked at the giant insect in front of him, and couldn't help but understand a lot of things.

The body of the World Tree is too large, and although it has spiritual intelligence, it is not capable of removing pests from its body. And the Shenmu Sect played the role of this scavenger, and every hundred years, they had to follow the ancestral teachings and help the World Tree get rid of pests.

And the place he was in now was probably the place where the Shenmu Sect collectively dealt with the pests on the trees.

He carefully observed the one hundred and eight Nian beasts, one by one, almost all of them in the appearance of various insects. It seems that this giant insect is very likely to be a strange insect bred by the Shenmu Sect, specially used to devour the parasites on the trunk of the tree in this world!

No wonder this insect only tried it at first, and then besieged it without attacking, I am afraid that it was a disciple of the Shenmu Sect who came to send food to feed it.

Cheng Mo sighed in his heart, the thousands of years of inheritance of the Shenmu Sect have gradually violated the original intention, deviated from the ancestral teachings, and in order to save trouble, he actually raised strange insects in the World Tree to act as manpower!

Although this strange insect also feeds on parasites in trees, it is also a much larger parasite after all.

He looked back at the circular passage that had entered here, and if his guess was correct, it must have been the bite of the strange worm in front of him. And he only saw these two passages, and there may be countless passages in other places that have been destroyed and gnawed out by this strange insect!

Has the Shenmu Sect changed from the role of guarding the World Tree to the role of enslaving the World Tree?

Cheng Mo didn't want to think about it anymore, at this point, he didn't want to treat this huge monster insect as his own pet anymore!

This time, Cheng Mo had murderous intent, and what appeared in his hand was no longer the magic sword Xuanyuan, but the sword destroying immortals.

Although the power of the Zhuxian Sword had been exhausted in the battle with Mu Youkun, there was a trace of the cutting law left by Xiahou Hao on it. In addition, during this period of time, he has absorbed and transformed part of the divine thunder supplement, so there must be no problem in dealing with this monster insect that has become bigger.

With the sword in his hand, he had even more killing intent emanating, which immediately stimulated the huge strange insect.

This strange insect suddenly opened its sharp teeth and huge mouth again, and let out a huge beast roar, but its body began to shrink, followed by the one hundred and eight Nian beasts directly exerted its might, and at the same time spit out a path of blue light at him!

This blue light was still one hundred and eight, and it actually condensed into a formation around him!

Heaven and earth are in a terrible array!

Although the Tiangang Four Evil Formations are not top-level formations, they also have countless changes and infinite power.

Cheng Mo squinted, and his divine sense instantly spread all over the four directions, and he also knew that this Heavenly Gang Formation was composed of one hundred and eight units. They can also divide and merge separately, seventy-two earthly evils, thirty-six heavenly gangs, and the power is unpredictable.

However, he was not very nervous at this time, after all, it was only one hundred and eight Nian Beasts that had formed this formation, and even if these Nian Beasts already had spiritual thoughts, they might not be able to exert the many changes in this Heavenly Gang Evil Array.

Sure enough, the one hundred and eight blue lights came to the body, Cheng Mo couldn't help but laugh in his heart, the power of these blue lights was too weak, although there were changes, but they were also very limited.

He twisted the sword and destroyed most of it directly.

Then he opened his mouth and blew, and suddenly the raging true fire flew all over the air, and the remaining cyan light was refined into nothingness by his true fire before it even made a sound.

Following his telekinesis to move again, the true fire in the air scurried around, igniting those nian beasts one after another.

These nian beasts were slashed and slashed by him before, killed and killed, and their breath was already so weak that they couldn't be weaker anymore, and they were burned by his true fire, and they suddenly turned into green smoke and drifted away without a trace!

Cheng Mo deliberately gathered the power of the true fire, and did not burn the spiritual thoughts of these beasts together.

At this time, he saw that the thoughts and bodies of these thinking beasts had dispersed, and he immediately opened his mouth and took back the true fire that filled the air, and then the Tai Chi Yuan Shen turned sharply, manifested on the top of his head, and suddenly inhaled!

One hundred and eight faint fluctuations were attracted by his Tai Chi Yuan Shen and threw themselves into it.

This one hundred and eight faint fluctuations, even those spiritual thoughts that have been formed by the Nian Beast, can also be used as an intelligent core, but compared to the intelligent core of a temple like the Supreme God, it is the difference between cloud and mud.

After receiving these one hundred and eight spiritual thoughts, he can integrate these spiritual thoughts into his own spiritual arts, so that his own spiritual skills can also give birth to pseudo-spirits, thus simulating the fourth realm of recitation: the point where the law refines its spirits.

It's just that this method takes a shortcut, although it can increase the power of the recitation, but it can't help your own realm, but if you use it more times, you will have a dependency mentality, so that your own recitation cannot go further.

Cheng Mo is naturally not this kind of short-sighted person, whether he wants to integrate with his own mental arts, he didn't think about it, he just thought it was strange, so he took it first.

The giant insect saw that its Nian beast was defeated by Cheng Mo, and its body immediately shrank rapidly, still turning into a cute green worm with a simple head and a brain, its head raised slightly, and nodded frequently towards Cheng Mo.

Is this begging for mercy?

Cheng Mo glanced at it, and gently stroked the little green wrapped around his hand, this little guy was still trembling at this time, and he didn't dare to show his head.

Cheng Mo said, "No one from the Shenmu Sect will come down to feed you, where is your lair?"

The little green worm was stunned for a while, and then he understood the meaning of Cheng Mo's words, nodded at him slightly, and with a flick of his small body, he shot towards Cheng Mo's right front.

The World Tree is extremely huge, such a green worm will definitely not be able to complete all the insect removal work, since it is raised by the Shenmu Sect, then it is likely to be more than this.

Cheng Mo followed the green worm firmly, and it took a quarter of an hour before he came to a smaller hole.

What I said here is smaller, and it is only compared to the passage when I followed up, in fact, this hole can still allow Cheng Mo to walk easily.

Entering this hole, Cheng Mo immediately felt the difference.

There is no formation in this cave, there is no seal, it seems to be an independent passage for this green worm.

In other words, even the disciples of the Shenmu Sect did not enter this cave, so they did not arrange the formation seal!

Cheng Mo couldn't help but be careful, this cave entrance was not too far from the outside area, but it was not sealed, which was really a bit abnormal.

He followed the green worm for another four or five hundred meters, and found that there was a fork in the road ahead!
