The lake is surrounded by valleys.

And the Xuan Qi in this neighborhood is not very strong, so no one usually comes here.

Taking a step back, even if someone came to the lake, they wouldn't have been able to discover the strangeness of the lake without coming into contact with the water in the lake.

When Meng Lieyan passed by nearby, he temporarily had a feeling that he wanted to break through, and he wanted to find a secluded place to cultivate.

Eventually, I came here and discovered the secrets of the lake.

In the inheritance of the ancient medicine god, many characteristics of flames have been recorded.

Therefore, as the recipient of the inheritance of the God of Medicine, Shen Feng judged the origin of this fire vein.

Generally speaking, the fire veins of the Purple Flame Earth's Heart Fire all grow at the bottom of the lake or at the bottom of the sea, and I don't know what the specific power of this fire vein is?

"Then let's go down and have a look. Shen Feng said.

Under normal circumstances, the fire vein will not attack people at will, as long as you don't enter the core area of the fire vein, there should be no danger.

However, if Meng Lieyan's ancestor really had an accident in the fire vein, then this fire vein would be very weird.

After all, Meng Lieyan's ancestor cultivated to the middle heaven rank of the ninth layer of the Heavenly Xuan Realm!

Shen Feng and the others exercised in their bodies, and after forming a layer of defense around their bodies, they jumped into the lake one after another.

Although there is the power of the fire vein in the lake, even Su Qinghan can resist it, after all, the power in the lake water is very weak.

This Purple Flame Earth Heart Fire is a very special kind of flame.

If a demon beast, or a monk, is burned by the Purple Flame Earth Heart Fire, then the skin on the surface of its body will not be damaged at all, not even a single hair will be burned off.

However, the blood in the bodies of the demon beasts and monks would gradually be incinerated by the Purple Flame Earth Heart Fire.

Therefore, the corpses of monks and demon beasts who generally died under the fire of the Purple Flame Earth Heart would be very intact, but all the blood disappeared, and they almost turned into a dried corpse.

This is also the reason why this flame is also called the fire of blood.

Shen Feng introduced the characteristics of the Purple Flame Earth Heart Fire to the rest of the people, after all, even Liu Yuanteng, who was a heart refiner, was very unfamiliar with this kind of fire vein.

It can be said that the Purple Flame Earth Heart Fire rarely appears in a single day, and even if it does, no one can tell where it came from.

After Su Qinghan and Meng Shixuan heard the terrifying nature of this flame, the bodies of the two of them couldn't help but become a little tighter.

Under the leadership of Meng Lieyan, the group kept swimming to the bottom of the lake.

About ten minutes later.

Meng Lieyan stopped in front of a cave at the bottom of a lake.

The entrance to the cave was large enough for four people to walk side by side.

The passage in the cave continued to stretch forward, and at the entrance of the cave a fiery force permeated the lake.

Of course, the power of this barrier is very weak, and the monk can pass through the barrier and enter the cave at will.

Unexpectedly, at the bottom of this lake, such a huge cave was formed.

Meng Lieyan was the first to pass through the weak barrier and enter the cave.

Subsequently, Shen Feng, Su Wanfeng and others also followed.

"Senior Shen, the fire vein is in the deepest part of this passage. Meng Lieyan said.

Shen Feng nodded and continued to walk deeper into the cave.

There was a heat wave all around, and the further you walked into the cave, the more the heat in the air became more and more turbulent.

Because Shen Feng and the others walked relatively slowly.

It was almost half an hour before they were coming to the end.

I saw that three meters in front of me was the end of this passage, and beyond the end, there was a space the size of a football field, which was filled with billowing purple flames, and the terrifying power was churning in it, even Liu Yuanteng and Su Wanfeng had solemn faces, if they let the two of them enter it, I am afraid they would not be able to hold on for too long.

Soon.

Shen Feng saw that on the left side of that space, there was a huge spar with a height of about one meter nine.

The most important thing is that inside this purple spar, a figure can be faintly seen, as if someone is locked inside the spar.

At this time, Meng Lieyan and others also saw this scene.

Meng Shixuan immediately said: "The person inside that spar must be the ancestor, we must rescue the ancestor as soon as possible." ”

Meng Lieyan agreed with his son's words, when he wanted to take a step.

Shen Feng stretched out his arm to stop it, and said, "Slow!"

"Your ancestor was trapped in the Amethyst Crystal, I didn't expect such a rare Amethyst to form in this fire vein. ”

"When your ancestor entered the fire vein before, he should have touched this purple flame crystal, so he was pulled into the spar by the devouring power in it. ”

"This Amethyst is the essence of the fire vein, and the Purple Flame Earth Core Fire here will be infused with fire energy every moment and enter the interior of the Amethyst Crystal. ”

"If we forcibly break it, it will only cause the Amethyst to burst, and the power in such a large piece of Asterite Crystal is enough to kill the powerhouse of the Heavenly Rank. ”

"Now if you want to save your ancestor, you must extinguish this fire vein, or absorb all the Purple Flame Earth Heart Fire in it. ”

At this, he paused slightly, and a look of doubt appeared on his face.

After taking a breath, Shen Feng continued: "It stands to reason that your ancestor is trapped in the Amethyst Crystal, and you should have been unable to hold on for a long time, is there any treasure on your ancestor?"

Hearing this, Meng Lieyan thought for a few seconds and said, "I remember that there seems to be a polar ice crystal on the ancestor's body. ”

Hearing this answer, Shen Feng's doubts were finally solved: "No wonder, this polar ice crystal can resist all kinds of flames. ”

"However, the Polar Ice Crystal is a consumable thing, and now we must find a way to rescue your Ancestor as soon as possible, otherwise he will definitely die in the Amethyst Crystal. ”

Between words.

Shen Feng's steps stepped out, and he got closer to some of the fire veins, and the burning stars and sky-swallowing white flames in his dantian were churning extremely powerfully.

A moment.

Shen Feng felt that from within the fire vein, a wave of energy fluctuations that were difficult to feel was seeping, and even this energy fluctuation was trying to enter his dantian.

This discovery made his face change instantly, and the steps under his feet suddenly retreated, and said, "Let's go, get out of here first!"

Meng Lieyan and Liu Yuanteng and the others trusted Shen Feng very much, so they naturally would not hesitate.

However.

That energy fluctuation seemed to sense that Shen Feng wanted to escape, so it no longer deliberately hidden, like a huge wave, rushed into Shen Feng's dantian.

The next moment.

The Burning Star and the Sky Devouring White Flame were all drawn out, directly into the rolling fire vein.

Right now, Shen Feng couldn't control the Burning Star and the Sky Devouring White Flame at all, and he had lost control of these two Heavenly Flames.

The scene just now happened too quickly, even Liu Yuanteng and the others only saw two clusters of flames rushing out of Shen Feng's body, and they couldn't tell what kind of heavenly fires they were?

Liu Yuanteng pulled Shen Feng and Meng Shixuan to rush out, while Su Wanfeng pulled Su Qinghan and Meng Lieyan.

The moment they swept out, terrifying flames burst out of the space, as if it were a rolling flood.

However, Liu Yuanteng and Su Wanfeng's speed was also extremely fast, when they rushed out of the cave at the bottom of the lake and rushed to the shore of the lake.

The water in this lake was burned with purple flames, and the water of the lake kept boiling, a terrifying heat, scattered in the air.
