Yun Xiao took out a short knife from his waist and cut open the belly of the giant crab, although it is said that the belly of the crab is much softer than the back, but it is also relatively speaking, at least this place is much harder than Yun Xiao's own flesh, and when it was cut, it made a strange sound.

"Hehe, that's pretty lucky!"

Yun Xiao stretched his hand in, touched it for a while, and then a touch of joy appeared on his face, and on the retracted palm, there was a bloody demon pill.

Generally speaking, in the body of a third-order low-level vein demon, there are not many demon pills that have been formed, and if you want to get a demon pill, you have to look at luck, and it can also be seen from this that Yun Xiao's luck has indeed come back.

The effect of a demon pill on Yun Xiao naturally cannot be ignored, but at this time, he just wiped the demon pill and put it on his waist, and then stretched out his hand again and touched the abdomen of the giant cancer vein demon.

When Yun Xiao's outstretched right hand touched a touch of warmth, Deng Shi was overjoyed, because he knew that his purpose of coming to Jade Melting Mountain this time was finally about to be accomplished.

Retracting his right arm again, Yun Xiao's palm was already a fiery red jade, and this jade was by no means different from ordinary jade, because in addition to a touch of warm power on it, it was also emitting a faint red glow.

"Sure enough, it's Flint Heart!"

Seeing the shape of this jade, coupled with the aura that was emitted from it, Yun Xiao no longer doubted, to be honest, at the bottom of the hot spring before, he was not 100% sure that it was the flint heart, because before he could sense it carefully, the jade had already been swallowed by the Cancer Vein Demon.

The real flint heart, although its internal fire attribute energy is extremely rich, but because it is at the bottom of this hot spring all the year round, it absorbs a lot of water attribute energy, and the two complement each other for many years, and finally form this flint heart with special effects.

Now that he has a flint heart, the heavenly and earthly treasures of Yun Xiaozhong and the power of the stone heart are also complete, so after looking around, he made up his mind to use the stone heart to refine his body here.

This place may be because of the existence of the Cancer Vein Demon, there is not even a trace of movement around, Yun Xiao believes that those outer Vein Demons don't know that this overlord is dead for a while, and they should not dare to come here to disturb.

Yun Xiao, who had made up his mind, saw his right hand on his waist, and then a turquoise jade bowl appeared in his hand, and the next moment, some strange things appeared next to him.

These things are naturally natural treasures that neutralize the medicinal properties of the stone heart, maybe they are not necessarily medicinal materials that grow in the soil, but any of them can have a special effect.

This is something that Yun Xiao finally found in the jade pot cave, if it weren't for the most important flint heart, I'm afraid he would have already used this stone heart to improve his physical strength in the Jade Pot Sect.

After preparing all these things, Yun Xiao reached out and wiped it on his waist again, and then a jade bottle flashed out, it was the jade bottle containing the stone heart.

Yun Xiao didn't hesitate, and directly poured the stone heart in the jade bottle into the jade bowl, a pool of black liquid exuded a trace of weird aura, but it didn't make Yun Xiao's movements stop at all.

You must know that Yun Xiao is a genuine mortal-level low-level vein refining master, and his vein refining technique is probably stronger than Zhao Ningshu or Xuan Zhi, because he has rich experience in vein refining in the previous life.

For example, at this time, the power of reconciling this stone heart essence is the memory inheritance of Yun Xiao's previous life Longxiao God of War, if it is not so, even if he obtains the stone heart essence, I am afraid that it will take a spirit level pulse refiner to reconcile it to a level that can be tempered by a cultivator in the early stage of the Gathering Pulse Realm.

"Pulse fire, now!"

Yun Xiao's mouth fell with a low shout, and immediately a blood-red flame appeared at the bottom of the turquoise jade bowl, and under Yun Xiao's control, the jade bowl would naturally not be damaged in the slightest.

Gurgle......

A moment later, the black stone heart in the jade bowl was already bubbling with a hot breath, and at the same time, bubbles were about to float up, making a smile appear on Deyunxiao's face.

"Quenching ginseng, condensate liquid, refining vine ,......"

A piece of heaven and earth treasure was burned into a touch of water by Yun Xiao's pulse fire, or a puff of medicinal powder, and finally they were all injected into the stone heart in the jade bowl, and some unknown changes occurred.

About two hours later, when Yun Xiao smelled a faint fragrance in his nose, he knew that the critical moment had come, only to see that he threw out the flint heart that he had just gotten into his hand, and actually threw it directly into the neutralizing stone heart.

This time, Yun Xiao did not use the pulse fire to melt the flint heart, because what he wanted to borrow was the power of the flint heart itself, and he also believed that the stone heart at this time could absorb the power of the flint heart as much as possible to reach a perfect level.

It turns out that Yun Xiao's experience in his previous life is by no means just talking, when about two hours have passed again, and after night begins to fall, the original black stone heart has a faint fiery red color.

The fiery red and pitch black are intertwined, and it looks strange and mysterious in this dark night, but in the previous life, I had seen this perfect stone heart of Yun Xiao, but I only had joy in my heart.

"It's time!"

The murmur in his mouth fell, Yun Xiao wiped his right hand on his waist, and a tall wooden barrel that had been prepared appeared out of thin air, and then scooped up a bucket of hot spring water next to it, everything was ready.

"Success or failure, in one fell swoop!"

Looking at the steaming hot spring water, Yun Xiao gritted his teeth and poured all the nearly a bowl of stone heart into the wooden barrel, and the next moment, the hot spring water that was still crystal clear just now instantly turned black and red.

Yun Xiao had already experienced, so he didn't think much about it, but directly stripped his whole body and jumped into the barrel, and even his face sank under the water.

"Ah, it hurts!"

Yun Xiao, who had just entered the barrel, first felt a hot burning pain, and then it seemed that some special energy forcibly pressed into his body, making his lips under the water open and let out a painful sigh.

It's just that all of this is expected by Yun Xiao, he knows that this stone heart refining body must be extremely painful, which is equivalent to refining the body belonging to the human body again and expelling the impurities in it, if you don't experience such pain, how can you achieve such an effect?

And Yun Xiao also knew that this time would never be too short, a few days would be at least, so after the initial severe pain, he didn't say a word.

............

When Yun Xiao absorbed the stone heart chalcedony and refined his body in this hot spring, at the southern entrance of this jade molten mountain, a strong figure came quickly.

If Yun Xiao was here, he might recognize this sturdy figure, which was Guan Tong that he had once gotten rid of not far from the north of the Jade Pot Sect, but Guan Tong's face was a little unsightly at this time.

To be honest, with the cultivation at the peak of the Gathering Pulse Realm, and the super genius who has stepped into the Chong Pulse Realm with half of his feet, he was teased by Yun Xiao before, which is simply a great shame for Guan Tong.

Originally, Guan Tong wanted to fight for the pain of losing five hundred points, and cleaned up Yun Xiao not far from the Jade Pot Sect, but in the end, he accidentally capsized in the gutter, and almost didn't escape from the hands of the night wolf owl at the peak of the third-order high-level.

That battle really made Guan General do his best, so it was difficult to get out, and from that moment on, he only had killing intent for Yun Xiao, even if this killing intent was what he had before.

Fortunately, Guan informed Dao Yunxiao that the place of his mission this time was Jade Melting Mountain, so he did not go in the wrong direction, and after more than half a month of traveling, he finally arrived at the range of this Jade Melting Mountain.

"Yun Xiao, wait, I will definitely not let you have a chance to get out of this Jade Melting Mountain!"

A voice containing resentment came out of Guan Tong's mouth, and then his figure quickly disappeared at the entrance of this jade molten mountain, bringing a strong wind, but it also looked extraordinary.

When Guan Tong's figure disappeared at this entrance for a few hours, another figure also came, this is a figure in green clothes, it seems to be a little thin, but there is a faint smile on his face, which looks chic and extraordinary.

"Hehe, Fire Spirit Crystal, this time I'm going to make a decision!"

The young man who called himself Shen Xiao let out a chuckle, and then his body moved slightly, and he disappeared at the entrance of Jade Melting Mountain like a ghost.

It's just that what Shen Xiao didn't notice was that after he entered the Jade Melting Mountain, a strange young man also appeared at another entrance not far away, but this person didn't say a word, and the movement that disappeared in the Jade Melting Mountain seemed to have never happened.

With the entry of these people, Jade Melting Mountain couldn't help but become extremely lively, but at this time, Yun Xiao, who was located in a hot spring place, didn't have the heart to care about this, because he had come to an extremely critical moment.

It has been seven full days since Yun Xiao entered the barrel to absorb the power of the stone heart, and in these seven days, the power of the stone heart has been refining his body all the time, so that his physical strength is also steadily improving.

It's just that the original plan was flawless, but after all, there was an accident, that is, Yun Xiao after this rebirth, underestimated the energy of the stone heart.

Or maybe he didn't have enough of the physical capacity of his whole body, and when he reached the seventh day, he suddenly found that the stone heart energy he could absorb was saturated.

The human body has a limit to the storage of energy, which also leads to the physical refining that they can accept, and there is also a limit.

At this time, Yun Xiao has undoubtedly reached this limit, but there is still a lot of stone heart energy remaining in the barrel, which seems to have become a deadly poison.
