Chen Cao looked at these plesiosaurs.

There is no mercy or sympathy here.

If Chen Cao doesn't kill them, they will kill Chen Cao.

This is the most primitive world, and the most primitive rules.

Every time Chen Cao killed a plesiosaur and absorbed the earth essence in their bodies, his body became stronger.

And after the earth essence in the body reaches a certain level, it begins to condense into a pill.

Chen Cao didn't need to deliberately condense it, the essence of the earth condensed by itself.

It's already done at the moment, but it's not enough.

It is not condensed enough, and the inner dan at this moment is still in a liquid state.

A larger amount of Earth Essence is needed to condense it.

And Chen Cao killed so many plesiosaurs, which also attracted more underground creatures.

There are strong and weak ones.

Weak underground creatures are larger rats.

They didn't dare to attack Chen Cao, but they were competing with Chen Cao for food.

Hordes were tearing at the carcass of plesiosaurs.

Chen Cao didn't have time to deal with these mice.

At that moment, the rats suddenly stopped eating, and their eyes were all focused on the vapor mist.

Chen Cao's pupils contracted suddenly, and something came over.

Suddenly, Chen Cao sensed danger.

Chen Cao immediately activated Tsing Yi Xia, and at the same time blocked the dark magma in front of him.

But the dark magma was the first to be pierced.

A force came with a force that could not be ignored.

Chen Cao was violently knocked out hundreds of meters.

This is what Chen Cao felt.

Tsing Yi Xia broke in an instant.

If he wasn't strong enough, this blow would be enough to kill him.

Chen Cao looked into the mist.

I vaguely saw a red mass.

It burns with flames all over its body.

Chen Cao directly released the current stored in the Eye of Thunder completely.

A terrifying electric current spreads in the mist of water.

The entire space was filled with electricity, making a crackling sound.

The creature's strange screams could also be heard in the mist.

It seems to work, the guy is not resistant to electricity.

Chen Cao slammed through the mist and rushed towards the flames.

Chen Cao was still startled when he saw this thing clearly.

It's a big bird with a flame burning.

It's not a big bird whose body is set on fire, it's a flame.

A thought popped into Chen Cao's mind, Immortal Bird.

Flames made up every inch of its body.

This is a real immortal bird!

The flame wings of the immortal bird flapped, and the surrounding steam mist was swept away.

At this time, Chen Cao had already arrived in front of him.

Chen Cao couldn't care about how hot this immortal bird's body was.

Anyway, it was a punch on the immortal bird.

The immortal bird was smashed away, and Chen Cao forced the immortal bird again.

Another punch landed on the body of the immortal bird.

The immortal bird pecked Chen Cao with its beak.

The blood on the immortal bird's body fell on Chen Cao's body, and Chen Cao felt a piercing burning pain.

If this continues, even if you kill this immortal bird, you will be burned to death.

Chen Cao didn't want to continue, so Chen Cao took out the guzheng and twelve stone swords.

Activated, twelve stone swords slashed at the immortal bird.

The immortal bird shouted loudly, and the stone sword caused great damage to it.

The immortal bird seems to be aware of its own time of death.

Its body suddenly began to contract, and for every minute it shrank, it became warmer.

Legend has it that the immortal bird has the ability to be reborn from the ashes, which is also known as Nirvana.

Chen Cao would not let it become nirvana, but at this time, its body had shrunk by half.

The temperature has increased several times, even if it is more than ten meters away, Chen Cao can hardly resist this high temperature.

And the stone sword melted directly.

This is a scorching heat that even the stone sword can't resist.

At this time, the immortal bird shrank by one point.

It can't go on like this.

Chen Cao released all the dark magma and wrapped it directly towards the immortal bird.

At this time, the dark magma also began to boil, like boiling water.

Chen Cao didn't know that dark magma actually had a boiling point.

However, at this time, Chen Cao was already difficult to ride a tiger.

Under Chen Cao's control, the dark magma pierced inward and shot through the body of the undead bird.

The nirvana of the immortal bird finally stopped, and so did the body.

At this time, there were no more monsters continuing to attack Chen Cao, in fact, since the appearance of the immortal bird, all the other monsters had fled.

Chen Cao walked towards the corpse of the immortal bird.

At this moment, the immortal bird is no longer as hot as before.

Its corpse was as calm as a normal creature.

Chen Cao discovered that the blood of the immortal bird was fusing with the dark magma.

Chen Cao was more concerned about whether there was gold in the body of the immortal bird.

However, when Chen Cao opened the body of the immortal bird, he found a golden bead.

Is this a purer earth essence?

No, this is already a Neidan, right?

Did you kill an immortal bird that had reached the emptiness of heaven and earth?

No, it should be the same as itself, it is only half done.

What it comprehends is the Chaos Void, and what it comprehends is the Chaos Void.

Chen Cao began to absorb the essence of the earth.

At this time, Chen Cao felt that his blood was ignited and boiling.

Chen Cao forcibly suppressed this feeling of dryness.

And the inner dan in Chen Cao's dantian began to become condensed and turned golden.

And the sphere of Nedan shows the pattern of an immortal bird.

Chen Cao felt the changes in his body, and all the weight-bearing feelings disappeared at this moment.

The sky and the earth are clear, and it is finally successfully completed.

The celestial patterns in the small world seemed to be ignited, and all the patterns were spread with red flames.

The diameter of the small heaven and earth is about fifty meters, and the shape is a hemispherical body, which is like a burning tree at the moment.

Collect! Chen Cao's heart moved, and the flames instantly dissipated and retreated into Chen Cao's body.

Chen Cao's consciousness moved again, and a flame instantly erupted at a certain location in the small world.

It's a good feeling to be in control of the world!

However, it is only within the small world, beyond the scope of the small world, Chen Cao is powerless.

Chen Cao's body was light, and the person was already floating.

Chen Cao felt that in the direction where the immortal bird appeared, there were more, more terrifying existences.

However, Chen Cao didn't plan to go deeper, it was already so dangerous here, and if he went deeper, he would only die worse.

So Chen Cao planned to leave.

Chen Cao easily returned to the waterfall and followed the dark river back to the underground lake.

At this time, Chen Cao had another idea, since the underground lake has other water sources, and the water source is likely to be on the ground.

So can you get back to the ground from the water intake?

Soon, Chen Cao found the water inlet, and Chen Cao went up the river along the water inlet.

Although the current is fast, for Chen Cao, such a turbulent water cannot pose a threat.

Finally, Chen Cao felt the outlet of the undercurrent.

Chen Cao kicked upwards hard, and finally surfaced.

But how is it so familiar?

Chen Cao glanced left and right a few times.

Is this your own home? Mirror Lake?
