Deep underground.

The Sword Venerable led Lin Chen down the stairs.

It's a bone-chilling place, several times colder than the frozen valley.

Even, Lin Chen felt extremely uncomfortable, and goosebumps got on his body.

If he stays for a long time, he is not sure if he can bear it.

If an ordinary martial artist comes here, he will freeze to death directly, and the weapons he carries with him will also be frozen to a brittle glass.

But the Sword Venerable, it seems that he has been here many times, and he has long been familiar with it.

Anyway, the five senses of the ancient martial arts powerhouse are very keen, and when they walk in the faint light, they will not worry about falling or stepping into the air.

And so they went down for a few more minutes.

What caught Lin Chen's eyes was suddenly a pool with a diameter of about two zhang, and a lotus flower poked out of the pool.

This lotus flower did not bloom, and the color was not at all the same as the outside, it was a pale jade color, and it could even be said to be the color of snow.

The faint fragrance wafted from it.

A layer of light looms over it, making it look particularly mysterious.

"What kind of elixir is this?" Lin Chen was stunned.

"The Earth Fire Blue Lotus has not yet bloomed," the Sword Venerable said, "This kind of lotus flower only blooms once in three hundred years, and the last time it bloomed was two hundred years ago. ”

"Oh, what's the use?" Lin Chen's heart pounded.

"Take it off and eat it, it will be of great benefit to you," said the Sword Venerable, "you stay for now, and I will come back to you in seven days." ”

As he spoke, the Sword Venerable walked back again.

Lin Chen looked at him, but he didn't stop him.

To be honest, he could have left such a Jedi himself, but it would take a long time.

After the Sword Venerable left, Lin Chen was not in a hurry, sitting cross-legged next to the pool, silently looking at the "Earth Fire Blue Lotus".

The name is strange, Qinglian can understand it, but where is the earth fire?

Could it be that the bottom of the pool leads to the fire?

If that's the case, then this kind of earth fire is a bit strange, otherwise this cave would not be so cold, but should be like a furnace.

Taking a deep breath of the aroma, Lin Chen felt comfortable physically and mentally, every pore was opened, and he wanted to sleep so comfortably.

It seems that this elixir, which does not have any toxicity, is indeed good for martial cultivators.

After thinking about it, Lin Chen made a bold decision.

He took off his coat and jumped directly into the pool, groping for the roots of the "Earth Fire Blue Lotus" and diving towards the bottom of the pool.

It was also very cold in the water, but it was about the same temperature outside, so Lin Chen gritted his teeth and dived.

The whole pool looks like a dug ancient well, the whole is straight down, and the light at the bottom is very sufficient, as if there is a flame jumping.

Opening his eyes wide and seeing the situation underground, Lin Chen was ecstatic in his heart.

It was indeed a fire underneath, but it was very special, the temperature was very low, and it was not affected by water, and it burned vigorously.

The earth fire emitted a kind of cold moon-like glow, which gave people a very comfortable feeling.

Searching for his memory, Lin Chen thought of the contents of the Nine Yang Refining Technique.

The reason why he thought that the level of Jiuyang Body Refining Technique was very high was because after the middle stage of this kind of body refining technique, it was very difficult to improve.

Be sure to cooperate with the Xenoflame, otherwise, there will be no further progress.

However, xenomorph flames are so scarce that it may be difficult to find one of them if hundreds of thousands of martial cultivators are mobilized to search the entire world.

I really didn't expect to meet here, it's a miracle from heaven!

Closing his eyes and meditating on a round of scorching sun in his mind, his body exuding a rich golden light, Lin Chen reached out and touched the earth fire with his palm.

There was a tingling sensation first, and then Lin Chen felt that a cool energy washed into his body.

He constantly runs the Nine Yang Refining Body Technique.

A thousand Sundays.

Two thousand Sundays.

Three thousand Sundays.

……

Here he completely forgot about time.

He has been running this alchemy technique until 100,000 Zhou Tian.

Suddenly.

The anxious shouts of the Sword Venerable could be heard from above.

Lin Chen opened his eyes and looked around.

The fire was completely gone, and it was so dark that I couldn't see my fingers.

But Lin Chen knew very well that he had completely refined that strange fire, and a blue sun seemed to rise in the sea of dantian qi, burning silently.

All the vitality has been constantly tempered by this cyan sun, refined, refined, purified, and refined again.

His vitality accumulation had fallen to one-fifth of its original level, but the level of purity was unprecedented.

The fire poison hidden in the heart is completely gone, as if it has met the ice and snow of the sun, and melted without a trace.

Stretching his body slightly, Lin Chen only felt as if he had been reborn, and his whole person was different from before.

The surface of his body no longer even emits golden light, but a kind of shining green light, as if he is the earth fire, and the earth fire is him.

"It's time to go back. With a kick of his feet, Lin Chen swam towards the top of the pool.

The surface of the pool was rippling, and he jumped out.

"Good boy, what the hell have you done?" the Sword Venerable was startled
