Immortal cultivation starts with copying.

Some cave entrances are covered with thick dust, and zombies are unwilling to enter, which is enough to show that it is dangerous for zombies inside.

The entrance to the cave was covered with dust, but Chen Yunhao believed in the ancient mirror and walked into the passage without any hesitation.

This passage is also long enough, and through these passages we can see that the strength of the sects here was also quite strong.

As he went deeper and deeper, Chen Yunhao felt the temperature rising little by little, and he even had to use his true energy to resist the high temperature.

In the end, even though Chen Yunhao kept circulating his true energy, beads of sweat continued to drip from his forehead, as if they had penetrated deep into the lava at the center of the earth, which shows how high the temperature was.

This passage runs diagonally underground and should be almost a thousand feet deep.

At the end of the passage is a cave. From a distance, you can see flames jumping in the cave and waves of heat blowing towards you.

After entering the cave, Chen Yunhao saw clearly that there was a deep pit on the ground with roiling lava in it.

No wonder the temperature here is so high, it turns out to be a place connected to the lava in the earth's core.

Chen Yunhao's attention was instantly attracted by the two treasures floating on the lava.

A golden fire lotus was floating on the lava. It was bigger than a human head and was in full bloom.

As the lava rolled, the fire lotus also floated up and down and left and right.

The Fire Lotus is a natural treasure with fire attributes. It is a treasure that is rarely seen in a thousand years. It can be used to refine elixirs for cultivators who have reached the realm of transformation to break through.

Even if he swallowed it raw, for Chen Yunhao, who practiced fire-attributed exercises, it would quickly improve his cultivation level, and it would be easy for him to break through three small realms.

Another treasure is a ball of fire only the size of a fist floating above the lava.

The flame was light blue and jumped around on the lava like an elf.

But as soon as Chen Yunhao appeared, the flame shrank back into the lava.

It is obvious that this ball of flame has intelligence and can no longer be called a simple treasure from heaven and earth. It should be called a spiritual object!

"What a great opportunity this is...!"

The sound of the ancient mirror rang out again.

This is truly a great opportunity. Let’s not talk about the fire lotus for now, as its effectiveness is limited after all.

Take that ball of spiritual fire for example. It is the spiritual object that every cultivator who practices fire-attributed techniques or has fire spiritual roots dreams of.

This ball of spiritual fire can benefit Chen Yunhao for his entire life. This is no joke, because the spiritual fire can be upgraded continuously with almost no upper limit.

As long as Chen Yunhao's cultivation continues to improve, he can find a way to improve his spiritual fire as well.

"Okay, but how do we capture this spiritual fire and how do we store it?"

Chen Yunhao was self-aware. The fire lotus was easy to capture since it was an inanimate object after all.

But the spiritual fire was not so easy to deal with. Once it entered the lava, he was helpless.

"That's not difficult at all. I can capture it right away and even teach you the method of refining it. However, I want half of this spiritual fire..."

Spiritual fire is also a type of energy and is equally effective in restoring the ancient mirror's strength.

"This..., taking away half, will it affect the spirituality of the spiritual fire?"

"I only want the spiritual fire. I'll leave all my spirituality to you. Don't worry..."

"make a deal……!"

The man and the spirit of the weapon reached a consensus in a short moment. It was good enough as long as they each got what they needed!

Chen Yunhao waved his hand downwards, and a whip-like rope rolled flexibly on the surface of the lava. Then he shook his hand, and the fire lotus was brought back in the air.

Chen Yunhao once sold the corpse of a monster in the transformation stage. It was a tendon from the monster's body, which Chen Yunhao made into a rope.

Chen Yunhao took out a jade box and carefully placed the fire lotus inside. When he was about to close the lid and put it away, he suddenly said something to the ancient mirror.

"First, make a copy of this treasure for me."

"You're bothering me with such trivial matters...!"

The ancient mirror flashed out from Chen Yunhao's dantian and said impatiently.

Although his tone was unfriendly, he still copied another fire lotus for Chen Yunhao after a burst of light.

Then the ancient mirror flew into the air above the lava pit, with the mirror facing downward, and a beam of fiery red light shot straight into the lava.

In a moment, the ball of spiritual fire slowly emerged from the lava.

Chen Yunhao had already put away the fire lotus and was staring at the lava.

Seeing the spiritual fire cautiously poking its head out a little bit, Chen Yunhao felt that it looked like a six or seven-year-old child trying to peek in and try to steal something.

However, the beam of light emitted from the ancient mirror seemed to have an irresistible temptation to the spiritual fire, causing it to slowly float into the air along the light.

Suddenly, the light emitted from the ancient mirror turned into silk-like fibers, like a fishing net, which trapped the spiritual fire tightly.

Then the ancient mirror flashed and returned to Chen Yunhao.

At this time, Chen Yunhao had an additional mantra in his mind, which was the fire control technique on how to refine spiritual fire.

The fire control technique was extremely sophisticated, and Chen Yunhao couldn't digest it for a while.

"When you return and master the art of controlling fire, I will give you this spiritual fire."

The light on the ancient mirror dimmed, and the spiritual fire was absorbed into it.

"Senior, do you know how to leave this place?"

Watching the ancient mirror disappear from his sight and return to his dantian, Chen Yunhao asked hurriedly.

"Under the sunken ship..."

After getting the information he wanted, Chen Yunhao turned around and returned the same way.

This place, which looks like an underground maze, is now very clear. It should be the headquarters of a sect in ancient times.

However, fierce battles took place here, and traces of the battles can be seen in many places.

Of course, the victorious side of the battle will definitely plunder the place thoroughly before leaving.

So as Chen Yunhao walked along, he basically didn't see any treasures left by the monks, even those that were scrapped.

Therefore, Chen Yunhao decided to leave directly. This trip was an unexpected one, but the gains were considerable, which was enough!

He returned quickly. Half an hour later, Chen Yunhao returned to the place where he parted with Rimbaud.

At this time, Rimbaud was sitting on a flat stone slab, quietly waiting for Chen Yunhao's return.

"Grandmaster..."

Seeing Chen Yunhao return safely, Rambo hurriedly stood up and greeted him.

Chen Yunhao nodded in response, and with a wave of his sleeves, several broken shipwrecks were swept aside by the wind.

A teleportation array was revealed under the sunken ship. It was a very small teleportation array that could only accommodate three to five people at most.

The appearance of the teleportation array is almost the same as the current one, and it is also inlaid with spirit stones all around.

Chen Yunhao casually threw out five medium-grade spirit stones and embedded them in the five bases of the formation.

The teleportation array, which had not been activated for who knows how many years, began to emit spiritual light.

"Let's go..."

Chen Yunhao stepped into the teleportation station and greeted the still dazed Rimbaud. In the blink of an eye, the spiritual light dissipated and the two disappeared.
