"Click, click!"

The moment the strange butterfly appeared, it was already desperate to flee into the distance!

"Want to escape?"

See this scene.

How could Chen Han let this guy go!

Immediately.

The hands were quickly put together, and the eight-grade silver flame that surrounded the body quickly converged and turned into a crazy torrent, sweeping towards the sky. Wrapped in silver flames, the strange butterfly suddenly let out a miserable cry, and its body burned into nothingness!

Call......

A long puff of turbid air.

Chen Han looked around.

It's just that.

Previously, the red-haired old man who was controlled by the strange insects, as well as Zhao Qingfeng's figure, had already disappeared into this Star Dou Mountain!

"Escaped!"

Chen Han frowned slightly.

"Silver Pupil Heavenly Eyes" slowly opened, and glanced around.

It's just that.

Even so, no trace of the other party was found.

Sighing secretly, the eight wings spread out rapidly, flying back towards the Sin City!

......

"What?"

Tower of Sin.

Yan Lao's eyes widened, he looked at Chen Han in horror, and couldn't help but say, "You say, is that a gray worm?"

"That's right, this weird little insect doesn't seem to be able to kill at all, and can only rely on fire to kill it. Chen Han said slowly: "Prince Rong was not able to come back, according to my guess...... It's very likely that I've encountered those weird bugs! Yan Lao, what are these bugs?"

"A monster!"

Monsters?

Hearing this, Chen Han couldn't help frowning.

If it's a monster, why can't the Emperor recognize this weird bug?

"This is not an ordinary monster, this is a weird insect born under the invasion of the Demon Qi of the Nine Shadows and Eighteen Blood Prisons, as well as the immortal qi of the Outer Heavens!" Yan Lao said slowly: "Tens of thousands of years ago, when the demons of the Nine Shadows and Eighteen Blood Prisons came to the mortal world, there was also such an insect plague! It's just that there were only seven or eight ...... at most."

Come to think of it.

Yan Lao immediately waved his right hand, and a gilded ancient book appeared in the void.

"It's all there!"

Immediately.

Chen Han took it and flipped it quickly.

Inside the tower, there was silence, only the sound of flipping books.

Chen Han has ten lines at a glance, and he will never forget it. Under his gaze, the major historical events of the mundane world were all remembered by him.

Finally.

When he was halfway through the page, Chen Han was stunned and found the approximate incident of the weird worm!

60,000 years ago.

There was indeed such an outbreak of insect plague, and eight people were controlled. These eight people are not afraid of life and death, and they don't know pain. Looks like people are not people, like ghosts but not ghosts...... Use transparent tentacles to devour everything to replenish your strength. They will actively seek out powerful people to parasitize, which is divided into four stages in total!

The larval stage - that is, the weird little worm that Chen Han saw!

Ovial stage - this is the strange egg in the head of the Gray-winged Angel!

Maturity – it's the weird butterfly!

Complete ——???

"Elder Yan, what's going on with this complete expectation, why are all question marks?" Chen Han couldn't help but ask out loud when he saw this.

"I don't know. Because, almost all the strong people who resisted the insect plague at the beginning have fallen. So there are very few records...... I only know that this final stage of perfection is almost equivalent to that of an immortal disciple, or a powerhouse in the realm of demon disciples!"

Whew-

Hear the words.

Chen Han couldn't help but gasp.

To know.

This time the outbreak of the insect plague is not like 60,000 years ago, there are only seven or eight at most. Even if Chen Han killed them, there were thirty or forty of them. According to preliminary estimates, this time there are about 1,000 of them. If there are a thousand more people in the mortal world at once, and there are only immortal realm powerhouses who know how to kill, I am afraid that it will be ...... The consequences are unpredictable!

"But!" Just when Chen Han was shocked, Yan Lao hurriedly said: "These weird little insects, if you want to reach the complete stage from the maturity stage, it is not so easy. They need to be constantly feeding and absorbing the power of living things. After it grows to a certain extent, it will evolve into the complete stage!"

I see.

The heart hanging in the eyes of the voice finally let go of a lot.

If this period of perfection were as rapid as the previous three periods, then the entire mortal world would be destroyed only overnight!

"Old Yan, I know!"

Arched his hand.

Chen Han left the Tower of Sin.

Now.

Chen Han needs to improve his strength quickly...... Of course, the quickest is to quench. Previously, in the battle with the Gray Winged Angel, if he hadn't gone through the second easy tendon forging, the opponent's punch would have broken his own muscles and bones that had already been smashed!

Even in that case, it would be extremely difficult for Chen Han to win!

......

looked at Chen Han who was leaving.

Yan Lao couldn't help but sigh.

Shake your right hand.

A crystal ball slowly flashed out and immediately appeared in front of him.

"Why?"

"Why?"

"Why?"

The old man said again and again. "Why is the future changing?"

"In the future I see, there is no outbreak of these insect plagues...... Is this the punishment of 'heaven' for us to peep into the future?"

"Poof!"

Old Yan's body was shocked.

A mouthful of blood spewed out frantically and spilled into the crystal ball!

Passed out.

......

Back to the Chamber of Secrets.

Chen Han has already started the third Yijian bone forging!

But.

In his mind, the image of his previous battle with the Gray-winged Angel always came to mind.

These spooky bugs have few weaknesses.

The only weakness is the fear of fire!

And.

Ordinary flames, for them, have no effect at all! At the minimum, they have to be eighth-grade flames. If you wait for these weird little insects to reach their full body, only the Nine Rank Dan Fire can kill them!

"It seems that I have to find the Nine Rank Golden Flame quickly!" Chen Han couldn't help but mutter. "Time is running out now...... If it weren't for the appearance of these weird worms, maybe I would have had enough time to ascend to the Twelfth Rank of Emperor Wu and survive the Nine Heavens Divine Thunder! But now, the appearance of these weird worms has disrupted my deployment and arrangement!"

Sighing slowly, Chen Han couldn't help but smack his mouth, and his entire body was soaked in the potion.

And at the moment.

The entire mundane world is in great turmoil at this moment.

When the weird worm is not occupying the human body, it has almost no attack power...... Even the lowest-level martial artist can crush him. However, these strange guys, once they occupy the human body and parasitize in the head, then they will be able to have the strength of the Martial Emperor realm!

But.

How many powerhouses of the Martial Emperor realm are there in the mortal world?

That's it.

A silent killing, unbeknownst to everyone, lasted for three days!

And then.

These people who were occupied by strange insects quietly gathered somewhere.
