When he came to a very ordinary sea area, the demon dragon stretched out its claws and a black circle appeared at a location on the sea surface, circling the sea surface of ten meters.

He said respectfully: "Master, it's here, and Obsidian dives here, then dives under the sea and eventually disappears."

"Um!"

Yu Guihai nodded, and his huge divine thought instantly penetrated the thick sea water and reached the bottom of the sea.

Then, he frowned. There was indeed nothing unusual here. The sea water depth was only a few hundred miles. Although it was far from comparable to the Earth's ocean in his previous life, it was nothing in the Wuhai Realm, and the depth of the sea was not rare.

However, this is exactly the abnormality.

The Demon Dragon is absolutely impossible to deceive him, so the Obsidian must have disappeared here, but even he can't see any abnormalities here, so that's very difficult.

"You stay here and observe the changes around you at any time. I'll go down and take a look." Yu Guihai became interested, gave a casual command, and then jumped into the sea.

Yu Guihai swam rapidly, and there was an invisible layer of energy on his body, which separated the sea water and could not wet his clothes.

Not long after, he arrived at the bottom of the sea. In front of him was the black sludge under the sea, and there was no abnormality at all. Even the divine consciousness probe could not find anything.

Yu Guihai wandered around for a while, but he didn't get anything.

He checked it out with his own hands. The sludge below was real. He even punched it out and burst out a large pit more than ten meters deep. There was still an ordinary subsea soil layer under the pit.

"This is strange. What's the problem?"

Yu Guihai thought in his heart, and his eyes kept looking around. The black sea water could not completely block his gaze. The ground of the seabed, which is hundreds of meters in radius, is within his patrol range.

"Hmm? There's a problem here."

Yu Guihai suddenly found a black stone not far away.

This stone looks ordinary, but there is silt nearby. Such a stone looks very abrupt. Moreover, this stone has not been before, so it must have been turned out from under the sludge when he bombarded the seabed.

He swam over and carefully investigated the stone and immediately discovered the clue.

This stone is extraordinary. The part of the exposed sea water is scanned with divine thoughts and is no different from the sea water, but the part of the stone buried in the silt is indistinguishable from the silt.

What's even more rare is that this thing can be hidden from him, the super strong man at the peak of the Void Refining Period, which shows his extraordinaryness.

Yu Guihai reached out and grabbed the black stone with an invisible big hand, and grabbed it directly.

The stone is in the shape of a pyramid. When you look closely, you can see the strange and obscure lines. When you grab it, the weight is similar to the silt under the sea. After grabbing it, the weight suddenly becomes exactly the same as the surrounding sea water.

"Obsida's disappearance must be related to this thing." Yu Guihai thought.

Suddenly, a sudden change occurred, and an invisible force suddenly burst out from the black stone, sweeping towards Yu Guihai.

Yu Guihai was stunned and was about to defend himself, but he found that this force was not a power of damage at all, but a power of teleportation.

So, he just mobilized Daoyuan to protect himself and did not resist.

After a blur before his eyes, Yu Guihai found himself in a dark space.

This space is not large, only a radius of more than 100 meters, half of which is a black stone platform with various life practice tools on it, like a place of cultivation.

The other half is a black water filled with demonic energy. Several black lotus float in the black water, emitting rich waves of demonic energy, which are all extremely precious potions. There is also a strange fish lurking in the black water.

Among them, the strength is only the Yuan-Type level and is not worth mentioning.

A huge monster was standing on the black stone platform, the missing Obsidian.

When he saw Yu Guihai, Hei Obsidian immediately paid a visit, "Watch the master."

"Why did you come in here?" Yu Guihai asked curiously.

"I don't know, as soon as I reached the bottom of the sea, I was suddenly pulled in by a pulling force." Obsidian replied.

Yu Guihai thought for a while and guessed a little [Biqudao www.biqudao.vip] The reason is that there are various decorative styles here. It is obvious that this place has a lot to do with the Demon Lord Blood Class, and it is even likely that it is a blood class.

.

Obsidian is a puppet of the blood class, and it may cause the reaction of the black stone as soon as it approaches.

"Do you know this place?" Yu Guihai asked.

"I don't know, my memory is only after the Wuhai Realm, and there is no memory here." Obsidian replied.

"Yeah!" Yu Guihai nodded, no longer asked, but began to check along the stone platform.

Through this inspection, Yu Guihai quickly discovered something important.

A black smooth stone tablet.

This object is the most abnormal in the entire space. Its material is extremely hard and seems to be able to accept external energy input.

As for other things, except for the many black lotus flowers in the pool, they are all ordinary treasure decorations, and there are no treasures that are valuable to him.

Yu Guihai tried it a little. Although this black stone tablet could absorb Daoyuan, it did not react.

So he thought about it, changed the nature of Daoyuan, took back the power of other Dao fragments, leaving only the power of Dao fragments in the Demon Realm.

Suddenly, the black stone tablet responded.

A stream of information emerged in my mind. It was a magic skill, and its name was a meaningless name in the demon world. This magic skill did not know the level, which was very different from the immortal method. It practiced bloodlines.

This is a universal magic skill, which is commonly used in all demon bloodlines, and of course its effect is far less than that of those specific bloodline magic skills. For example, the eight-song clan must have specific bloodline cultivation methods.

Unfortunately, Yu Guihai could not obtain it, so this universal magic skill was more useful to him. Once he was integrated into the Hunyuan Dao Art, this magic skill could be practiced even with the power of blood.

The limit of this magic skill is in the mid-stage of the Cave Void Period, which is obviously the cultivation method of the Demon Lord Blood Class. This place is also within the space treasure of the Demon Lord Blood Class.

However, Yu Guihai was a little surprised. He didn't know why the blood class placed such an important inheritance treasure here instead of carrying it with him.

He didn't think much about it and then continued to check the information.

In addition to this magical skill, there is also some information in the stone tablet, which is about this space.

It turns out that this thing is not simple either, it is a treasure weapon of Void Inn.

This object is refined using special Void Star iron ore, and can also withstand a certain degree of void rays and other dangers, but cannot fly.

Because its material is far less than that of pure Void Star Iron, it cannot bless too many exquisite functions.

This object has a magic array that hides itself, which can be automatically disguised to prevent external exploration. However, this magic array will also block internal exploration of the external environment.

Therefore, this treasure can only be rested and restored in it. If it is allowed to fly, it will fly around like a headless fly, which is a desperate situation in the void.
