Facing the overwhelming green liquid, the Cyan eye royal fly looked as if it had met a powerful enemy, and suddenly flapped its wings to dodge it.

Witnessing this scene, the crowd couldn't help but look at each other in dismay. None of them knew what was going on.

In fact, there were many things they did not know.

This giant green caterpillar in front of him was a mutated species. It was innately fond of eating vegetarian food. After that, it would find a place to hide and slowly digest them.

Obviously, the reason it came out this time was to once again eat grass.

In the end, they did not expect to meet their natural enemy, the Cyan eye royal fly.

But this mutant caterpillar is not a soft persimmon.

Due to its normal eating habits, there is a large accumulation of acidic substances in the abdominal cavity.

It was the green liquid that it had just spat out.

This green juice had a strong corrosive property. Once contaminated, it could corrode.

The reason the Cyan eye royal fly avoided it was because its pair of transparent wings were relatively weaker. Once it was contaminated with the green juice of the caterpillar, it would be corroded.

Once the wings were corroded, losing the ability to fly would undoubtedly be fatal for a species like the Cyan eye royal fly that was flying in the sky.

However, the matter was obviously not that simple.

As the natural enemy of the mutated caterpillar, Cyan eye royal fly had its eyes on it and wanted to kill it.

In the blink of an eye, the Cyan eye royal fly and the mutated caterpillar in the swamp began an unprecedented match, which opened the eyes of all the martial cultivators in the mortal world.

They finally understood the meaning behind Qin Yu's words just now.

The Cyan eye royal fly would not attack them because it already had a better prey.

The caterpillar was a mutated species, and as a Demonic Beast, it was a great tonic for the Cyan eye royal fly.

Qin Yu led the group of people and did not leave either. Standing in the distance, he let them witness the entire process of the Cyan eye royal fly hunting the mutated caterpillar.

This was the biological chain of nature, and it gave them an important lesson.

The core content of this course was that no matter where, the law of the jungle was the same. If you didn't work hard, you would be eliminated by the world.

Or to be robbed.

Only by becoming stronger would he have the opportunity to establish himself in the world.

Just as they were watching the two Demonic Beast fight, a group of people suddenly appeared at the outskirts of death swamp.

There were around ten people in this group.

They were all gathered behind a proud white-clothed youth.

What was worth noting was that there was the word 'pill' embroidered on the clothes of this group of people.

The origin of the word 'pill' was not small.

Because it represents the 'Dan Sect' of Cultivation Realm.

Dan Sect was the Cultivation Realm, one of the five first-rate cultivation sects.

Within the Cultivation Realm, one would possess absolute strength.

As a disciple of the Dan Sect s, they were an existence that was respected by everyone in the Cultivation Realm.

Thus, they were born with a sense of pride.

Only, they did not know how the disciples of the Dan Sect had come to this remote place!

The arrogant white-clothed youth looked at the endless death swamp, and a look of disdain flashed past his eyes.

"Is this the death swamp? "He doesn't look that good either!"

"That's right, I really don't understand why Deacon Lu wants us to come to this remote place to train!"

"This place is filled with aquatic plants besides the quagmire. I think we should go back and cut some grass to feed the horses!"

The people behind white-clothed youth all spoke out, and started to chat with each other in disdain.

So it turned out that this group of Dan Sect disciples was sent by the deacons of the sect to train here.

However, being arrogant, they would naturally not spare a glance for the ordinary death swamp.
