"The yin energy here is all coming from here. Beitang Yu thought to himself.

In the water of the Ruthless Sea, Beitang Yu felt the existence of a large amount of Yin Qi, and these Yin Qi were about to materialize, and it could be said that these waters were all condensed by Yin Qi.

And such a strong yin qi, naturally is interested in some creatures that like yin qi, the black water snake lives here, it is not unreasonable, the yin qi here can definitely make it have a lot of growth, even if the monster beast creatures grow slower than humans, but the growth of a thousand years, it is also a big evil.

Beitang Yu guessed that in the Ruthless Sea, there should be materials with Yin Qi attributes, and the treasures did not dare to think about it, but there would definitely be no shortage of Yin Qi superb materials, but there was a black water snake in the Ruthless Sea, even if someone guessed that there were good things here, it was estimated that no one would dare to find them.

Beitang Yu only stayed at the edge of the Ruthless Sea for a while, and immediately sensed that something in the Ruthless Sea was staring at him, and what could make him feel a trace of urgency was the black water snake squatting in the Ruthless Sea.

"Come out, I know you're coming. Beitang Yu shouted in the direction of the ruthless sea.

Under Beitang Yu's voice, a huge black head rose silently from the Ruthless Sea, and the big head of the Black Water Snake appeared, without causing a trace of movement, which shows the special nature of the Ruthless Sea and the control of the Black Water Snake after living here for so long.

The lantern-sized pupils of the Black Water Snake stared at Beitang Yu, and felt that the aura on Beitang Yu's body was not ordinary, obviously not a soft persimmon, but the Black Water Snake was not a simple commodity, although it did not rashly make a move on Beitang Yu, it still issued a warning to Beitang Yu.

The Black Water Snake is not a good person, and it will not let go of anyone who dares to run to the Ruthless Sea or other things, no matter what the reason.

And the situation of Beitang Yu can be said to be the first time that the Black Water Snake did not attack as soon as it appeared, but stared at Beitang Yu from afar.

"I said, old black, you should be able to understand me, how about you come and mess with me? I can make you stronger. Beitang Yu said bewildermently at the Black Water Snake.

The Black Water Snake understood Beitang Yu's words, but the arrogance of the Black Water Snake could not have allowed it to follow a human? Moreover, this human didn't look much stronger than it, so the Black Water Snake would not believe that Beitang Yu could make it stronger.

"Don't you believe it? Indeed, there is no other way to make you stronger in this world, but if there is nothing in this world, there is no other world? I'll show you something else. Beitang Yu said bewildermently at the Black Water Snake.

The Black Water Snake aroused some interest in Beitang Yu, those monks who were weaker than it were all its food in front of it, but there would be no other results, only the fate of being eaten by it.

And Beitang Yu wanted to show it something, but the black water snake stared at Beitang Yu humanely.

Beitang Yu took out some things from other worlds and chatted with the Black Water Snake, and at the same time made out some cultivation systems that this world did not have and talked to the Black Water Snake, and finally talked about Heavenly Court, Hell, and other places.

The Black Water Snake looked at the abilities and items that Beitang Yu continued to display, and it was also very puzzled in his heart, because what it saw was something it had never seen before, but the Black Water Snake was not stupid enough to believe Beitang Yu with these.

Because of the intelligence of human beings, it can be said that they can come up with all kinds of tricks, let's just say that it is still possible to get some new tricks to deceive the Black Water Snake, if it weren't for Beitang Yu's strength, the Black Water Snake would not have been inked here with Beitang Yu at all.

"It seems that Lao Hei you don't believe it, but it's okay, the purpose of my coming to this world is to collect the Book of Heaven, and I will leave after I finish collecting the Book of Heaven, and then you can do it." Beitang Yu said to the Black Water Snake, and then went to look for the Blood Cave.

The Dripping Blood Cave is near the Ruthless Sea, which Beitang Yu is still clear, but where is it, Beitang Yu still has to look for it.

And in this dark area, Beitang Yu and Bai Hou quickly found out the area of the blood dripping cave through scanning and perception, and the black water snake also came out of the ruthless sea at this moment, following in an area 10 meters away from Beitang Yu.

Beitang Yu was not worried about the Black Water Snake attacking him at all, if the Black Water Snake really attacked him brainlessly, then he would also let the Black Water Snake know the fate of being killed.

"Old Hei, do you have a way to open this enchantment?" Beitang Yu said to the Black Water Snake.

The black-hearted old man set up the blood dripping cave in such a place, Beitang Yu didn't believe that he didn't let the black water snake help protect it, just like the water unicorn in the Qingyun Gate, Beitang Yu felt that the black water snake must be the guardian demon beast that the black-hearted old man put here.

However, the Black Water Snake is not the kind of person who is good at the Water Qilin, after the black-hearted old man hangs up, the Blackwater Snake is estimated to have only taken a fancy to such a good place to survive as the Ruthless Sea, and the others will not be ignored, even if it is a disciple of the Blood Refining Hall left by the black-hearted old man, if he dares to come here, it is estimated that the end will be the same.

The Black Water Snake hissed twice, and finally stared at Bei Tang Yu, so that Bei Tang Yu could feel the humanized expression of the Black Water Snake when he looked at it, this was a joke that wanted to see himself.

"Old black, you're not authentic. But since you don't help, I'll do it myself. Beitang Yu smiled and said.

The blood-dripping cave has an enchantment arranged by the black-hearted old man, unless there is a bloodthirsty bead, otherwise it cannot be opened, and the consequence of forcibly opening it is to destroy the blood-dripping hole.

Beitang Yu naturally didn't want to destroy the Dripping Blood Cave, once it was destroyed, then where would he go to get the first volume of the Book of Heaven? The first volume of the Book of Heaven was not hidden on something like other Heavenly Books, but was engraved on the wall, and destroying the Dripping Blood Cave was equivalent to destroying the first volume of the Book of Heaven.

"Psychic technique!" Beitang Yu directly summoned the six puppets, among the six puppets, the Shura Dao Death God and the Heavenly Dao Tsunade are all able to have some enchantments and seals, although the Death God system and the Hokage system are different, but there are still a lot of common techniques in some aspects.

Beitang Yu connects with the eye of reincarnation, and naturally he is also looking for a way to break the enchantment, and if he doesn't have a key to open the door, then he will find a way to pick the lock, and he will not necessarily smash the door.

When Beitang Yu was busy, the Black Water Snake was about to see Beitang Yu's jokes, and finally there was a slight crisp sound, and the enchantment shattered.
