After leaving the place where the mother was placed, Liang Yu did not return to Linyang Prefecture immediately.

At this time, he was still wandering in the hermit-controlled area. Because of the supernatural powers of the Divine Turtle Hidden and the Mysterious Snake Flash, Liang Yu didn't have to worry that the guys from the Hidden Clan would find him, even if he found the unlucky one, he didn't know who it was.

Liang Yu's wanderings were not aimless, he was searching for something, some heaven and earth treasures that could be integrated into his bones.

Since he successfully turned and tempered his skin, in the conversation with Ming Yang Daozun after he came back, he finally realized how difficult the test of the first heaven he had encountered was not simple. At the same time, he also had an intuition that the test of every day in the future would not be simple.

In order to ensure his safety and improve the success rate of each physical tempering, he consulted his master very seriously, and also consulted a lot of classics. Zuihou, he finally found a more difficult, but should be very effective.

It is to find the heaven and earth treasures that can be effectively fused into the tempering parts, and improve the basic quality of the corresponding parts. The higher the underlying quality, the more likely it is that Zuihou will succeed and the less risk it will be.

However, the difficulty lies in the fact that such heaven and earth treasures are already very rare and very rare in the Qiankun Continent!

This time, what Liang Yu was looking for was something that could be integrated into the bones, and things that could be integrated into the bones, Liang Yu only knew three kinds under the guidance of the classics and Ming Yang Daozun. They are: rootless wood, iron pith and dragon's beard grass.

Among them, rootless wood and iron pith are described in the classics, and it is also noted that rootless wood should be found in extreme yin places, and iron pith should be found in extremely hot places, such as the core of magma.

As for the dragon beard grass, Ming Yang Daozun also heard from his master, so it was already more than a hundred years ago, and the place where it probably appeared was a Jedi called Beast Yuan, which is said to be a companion plant in the lair of a high-level spiritual qi beast with the blood of the dragon clan.

On the Qiankun Continent, there are both extremely yin land and extremely hot land, and they are all within the scope occupied by the Yin clan. So Liang Yu has no scruples about searching, anyway, it is now a borderless land, and if it was placed in the past, it would have to take care of the nearby shili.

As for the beast yuan, Ming Yang Daozun is not very clear, so he will not consider it for the time being.

Now, Liang Yu is walking all the way to the closest extremely hot place to him, Huoyun Valley.

Located at the junction of Chiyang Prefecture and Turu Prefecture, Huoyun Valley is an active volcanic group, with volcanic eruptions all year round, columns of smoke that soar into the sky all year round, and the air is filled with the smell of flames and pungent sulfur.

It is precisely because of this that the cultivation environment here has always been poor, so there are basically no monks here, let alone a cultivation sect. Of course, the Hidden Clan didn't care too much about this place, although it wasn't really worthless, but they didn't have time to tap into the resources here.

The reason why it is said that this place is not worthless is because there is a very special fire attribute ore produced here, which is an excellent material for refining fire attribute spirit weapons. However, because the conditions here are too harsh, monks who do not have a certain level of strength will not easily set foot here.

However, at this time, a figure appeared within the range of the Fire Cloud Valley, and it was still approaching the core area at a very fast speed, not thinking about the occasional ore searcher.

This guy who suddenly appeared was naturally Liang Yu, and his target was certainly not a fire attribute ore. His goal is the iron pith that may or may not exist here.

At this time, a layer of spiritual power shield had appeared around his body, blocking the extreme heat from the outside and keeping it cool.

In fact, in this place that is still not a small distance away from the core area, even if Liang Yu does not hold up the spiritual power shield, the temperature of the outside world will not bring any harm to his skin, because the quality of his skin has almost reached the point of invulnerability after being tempered by the yin and yang winds. It's just that his clothes can't do this, although the water spirit robe is okay, but he can't go into battle in a vacuum!

Soon, Liang Yu came to the edge of the core area. What caught my eye was a magma pond composed of fiery red magma, like a cauldron boiling a pot, and the magma tumbled up and down, emitting hot gas.

Without the slightest pause, Liang Yu continued to fly inside, but the speed of the flight was not very fast.

In the core area of the Fire Cloud Valley, although the conditions are very harsh, it does not mean that there is no breath of life. In fact, there are still some special people living here with extremely tenacious vitality.

Soon, Liang Yu saw these guys.

Crocodile-like creatures emerged from the magma lake, their eyes flashing with bloody eyes, as if they had seen a delicacy, and in fact they also regarded Liang Yu as a delicacy.

"Whoosh!"

A fiery red arrow shot out of the magma, only towards Liang Yu. What's even more surprising is that this fire bonus arrow turned around on its own in mid-air, as if it were alive.

In fact, it's alive. It was the Fire Cloud Beast that lived in the magma here and looked a little like a crocodile, and this guy actually took the initiative to emerge from the magma and launched an attack on Liang Yu.

After seeing this expected attack, Liang Yu gently stretched out his hand, grabbed it by the neck, and grabbed it in his hand. Liang Yu's timing was very accurate, no more, no less, and he caught the idea at once.

Suddenly, this rash attacker realized that his attack had failed, and had become someone else's prisoner in an instant, and after struggling a few times without any hope, he simply drooped down.

Seeing this gadget, he gave up resistance, and Liang Yu couldn't help but look at it carefully. The Fire Cloud Beast that was caught by himself was only more than a meter long, and it was equivalent to a third level in terms of momentum. After a closer look, Liang Yu found that the Fire Cloud Beast's mouth was really long, and if it was allowed to open freely, it should be described as a bloody mouth.

Judging from this little guy, the teeth in his mouth are already very sharp and sharp, like a sharp knife, and the tip is actually red, as if it is coming out of the fire.

For such a little guy, Liang Yu naturally had no intention of hurting it, and casually threw it back into the magma. After this guy fell into the lava, he immediately got into it, and there was no trace of him. Not only him, but even the other low-level guys were also frightened by Liang Yu and hid.

Then, Liang Yu continued to rush inside. Soon, he felt a more powerful breath of life from the magma.
