I saw four black-clothed men fleeing out of the cave in a hurry.

"Roar, roar, roar......"

The huge roar continued to come out of the mouth of the cave, only to see a two-zhang long thunder dragon chased out of the hole, the giant hammer-like dragon tail was constantly flailing, towards several black-clothed people quickly smashed, the four black-clothed people dodged as fast as possible, causing a huge force to hit the ground heavily, and the cracks on the ground spread rapidly.

The huge shock wave knocked down a high-ranking Battle Emperor Realm powerhouse, and then before he could react, the giant tail like a sledgehammer slammed into the body of the man in black.

"Poof!poof!poof......"

Blood splattered, and the black-clothed man lying on the ground quickly turned into a puddle of bloody mud, and the thunder dragon continued to pursue the three black-clothed men, and the huge dragon tail was still waving.

"Bang bang bang bang bang ......"

The giant tail of the brontosaurus and the ground were constantly clashing, and a huge sound resounded throughout the forest.

"Hey, you guys are waiting for me here, and I'll see what is in this cave. Zhou Yi said.

"Eh, my lord......" Without waiting for a few people to answer, Zhou Yi turned into a red ray and shot straight towards the cave.

Several people couldn't help but worry a little about Zhou Yi when they saw the tragic scene of the man in black just now.

Zhou Yi finally entered the cave, the first thing that caught his eye was a long corridor, on the wall of the corridor every two meters was inlaid with a football-sized crystal nucleus, and the colors were different, but these crystal nuclei had a common feature, that is, from the inside of the crystal nucleus exuded a palpitating fluctuation, Zhou Yi had seen many high-grade crystal nuclei in the underground treasure house of the Great Cadre Academy, according to his judgment, all the crystal nuclei here should be the crystal nuclei of the ninth-level demonic beasts.

Zhou Yi was slightly shocked, this thunder dragon's hand was really bigger.

Zhou Yi continued to move forward, when he was traveling nearly a hundred meters, Zhou Yi's eyes suddenly opened up, this is a huge square of nearly tens of thousands of square meters, on the top of the cave inlaid with hundreds of huge demonic beast crystal nuclei, illuminating the entire square, not far from Zhou Yi is a pool of dark red blood, a trace of blood smell spread in the space, Zhou Yi suddenly remembered, this must be one of the men in black turned into blood under the giant hammer, he saw that only four people escaped from the cave.

Moreover, there are ten directions above the square, and there are four white giant eggs on the licorice opposites, and the giant eggs actually exude a faint yellow luster.

Zhou Yi slowly approached the giant egg, exuding the breath of the earth element on it, the powerful fluctuations were terrifying, there were a large number of yellow crystal nuclei around the giant egg, judging from the energy fluctuations of the crystal nucleus, at least the eighth-level demonic beast, he guessed that this egg must be a thunder dragon egg, it turned out that the thunder dragon was an earth attribute dragon.

Suddenly, Zhou Yi's eyes aimed at a huge pool, there was a spring gushing out of the pool, Zhou Yi slowly approached the pool, a warm breath came to his face, there was a hot spring in this cave, and this spring contained a powerful breath of life, Zhou Yi was slightly frightened.

When he stayed around the pool, he was even more surprised that there were several giant eggs floating in the pool, and they emitted various colors of light, and the energy fluctuations that spread out from them were comparable to those of the Thunder Dragon.

There were still a lot of eggshell fragments around the pool, and Zhou Yi guessed that in addition to the dragon eggs in the grass nest, these dragon eggs must have been hunted by the thunder dragon.

Looking at the broken egg skin on the ground, this must be the result of the Brontosaurus eating.

Zhou Yi kept looking in this dragon cave, wanting to get some other gains.

But apart from what he saw, there was nothing else special, and if he went out, he would definitely gain something, so he was wondering what to take from the dragon cave.

He walked towards a thunder dragon egg with the most radiance, Zhou Yi knew by feeling that this dragon egg must be about to hatch, and the energy contained in it was also the most powerful, and then he put this dragon egg into the space ring, and his eyes turned to the other three dragon eggs, forget it, just stop in moderation.

He walked towards the hot springs and put all the dragon eggs into the space ring, there were seven dragon eggs of various attributes, which didn't belong to the thunder dragon originally, so let's take them all.

He turned around and was just about to get out of the hole, a trace of doubt in his heart, he thought that the spring water was alive because of the existence of dragon eggs, but in fact, it was not, when Zhou Yi took out the dragon eggs, the spring water was still full of vitality, Zhou Yi quietly watched the spring water, and the vitality floated between the springs like a warm current.

Zhou Yi leaned down and plunged his right hand into the spring water, he felt the slightest vitality pass through his right hand and spread throughout his body, that feeling actually made the cells in his body jump, and even the Lin Chao in his eyebrows was trembling slightly.

Zhou Yi does not have any dark diseases in his body, and if there is a dark disease, he will definitely recover in this spring full of vitality.

Zhou Yi suddenly realized, just at the beginning he saw seven dragon eggs soaking in the hot spring, and there was still a trace of puzzlement in his heart, and now he finally understood that the eggs soaked in the spring water were to enhance its vitality. He must find a way to get some spring water from here, which will be of great use in his hands in the future. He searched around, and finally found a broken eggshell that was not very powerful, filled it with it, and put it in the spatial ring.

"Bang bang bang bang bang ......"

At this moment, Zhou Yi heard huge footsteps like ten thousand dragons galloping, and he rushed towards the entrance of the cave as fast as he could.

When Zhou Yi came to the entrance of the cave, he didn't see a thunder dragon, but the sound of huge footsteps was still ringing, and Zhou Yi knew that the thunder dragon population must be not far away. He quickly rushed in the direction of the Parrs.

"Your Excellency, are you alright? Several people saw Zhou Yi and hurriedly asked.

"It's okay, let's run. Immediately, several people quickly ran into the distance.

The Brontosaurus population finally came to the entrance of their cave, only to see three huge Brontosaurus holding three huge beasts in their mouths, which were more than twice the size of the Brontosaurus.

"Roaring ......"

The roar was gentle, as if calling for a companion to eat.

But there was no response from the cave.

"Roar, roar, roar......"

After a few roars, there was still no response in the cave, and one thunder dragon walked towards the cave, while the rest of the thunder dragons waited quietly at the entrance of the cave.

"Roaring ......"

An angry roar came from the cave, and several thunder dragons quickly ran towards the cave.

In an instant, several thunder dragons let out an angry roar, and a terrifying aura spread from the entire mountain stream.

Zhou Yi and the others had already run for dozens of miles, and Zhou Yi finally stopped.

"My lord, what the hell is going on. Parr asked, puzzled.

Zhou Yi smiled mysteriously.
