A trip to the bottom of the sea made Qin Feng lose his Thousand Evil Tai Sui, but he gained a very interesting brain.

However, Brain Girl is right, it does help her in some way.

As she said, the body can disperse some brain cells into the brains of some low-level marine fish, and then send them out of the sea, search widely in the sea, and constantly return information. As a result, the Brain Girl knows everything about the situation in this sea!

Therefore, when Qin Feng said that he wanted to find a few fierce demon kings to kill, the brain girl immediately listed more than a dozen demon kings for Qin Feng to choose from.

Each of them is a master at the level of the Demon King, and even one is close to the level of the Sea Emperor!

Qin Feng was overjoyed in his heart.

Although this brain girl has a lot of abilities that she still doesn't know, this one magical power is enough to save herself a lot of time and trouble.

But—

There were many choices, which made Qin Feng a little undecided.

"In this way, I said the conditions, you help me screen it first!"

I can't go to every single one, I don't have that much time. And the brain girl basically still knows something about the situation of these demon kings, so Qin Feng decided to use the elimination method first.

"That's good, you say!"

Qin Feng thought for a moment and put forward his own requirements: "The best thing I need is the kind of demon king who is super big, powerful, and fierce! In addition, in terms of strength, it is best to be at the level of a demon king who has just advanced, well, that's almost it!"

"According to your requirements, there are three-headed demon kings who can satisfy you, you can consider it yourself. After speaking, the brain girl instantly transmitted the relevant information of the three-headed demon king into Qin Feng's mind through her mind.

The speed is very fast and the efficiency is very high, Qin Feng is very satisfied.

At this moment, he was a little glad to have found this brain girl as a helper, it seems that when he enters Huangquan in the future, she will definitely be a big help for himself!

Qin Feng immediately flipped through the comparison in his mind, and a trace of doubt appeared on his face.

The three-headed demon kings are-

The big catfish blood lizard king, the seven-headed storm whale king, and the blood taurus barbarian king!

And underneath their names, there are strange use of some simple numbers and some notes.

Five, five, eight!

"What do these numbers mean?"

Qin Feng's question is here.

is also a demon king, why is the first two the same, five, and the latter one is only marked as nine? This made Qin Feng a little puzzled.

"This is the degree of danger, I evaluate it myself! From one star to ten stars, one star represents a slight danger, and ten stars represent certain death!" The voice of the brain girl came into her mind, and she explained this.

Qin Feng was stunned.

Because the brain girl is so smart, she likes to formalize and fix many things! In Qin Feng's opinion, it is also quite interesting, at least at a glance.

"It's just this nine-......"

He frowned, and asked: "The cave of the Blood Golden Bull Barbarian King, why is it nine stars? This is just a demon king who has just advanced, how can it be so powerful? The other two demon kings plus one can only be regarded as seven or eight stars at most, why does it have such a high degree of danger?"

Qin Feng's question was already expected by the brain girl.

Therefore, her explanation immediately came to her mind, but her voice was quite solemn, and she seemed to have a great fear of this place.

"I'm also very puzzled by this! There, I sent several waves of fish and beasts to investigate, and in the cave, there was obviously only one blood golden bull barbarian king, although there were occasional cases of being devoured, but most of the fish and beasts also came back alive. However, shortly after his return, he died mysteriously!

The cause of their death, I have studied, there is nothing wrong with the body of the fish, but all the bones in the body are cracked and turned into a puddle of powder!

It's like something evil has sucked the essence of the bones dry!

It's weird!

That's why I've marked that area as a forbidden place, and I've rated it as a nine-star for its danger!"

"Oh?"

Qin Feng's face showed a hint of surprise.

"Bone eater, hehe, that's interesting! Let's go, let's see!"

Brain Girl: "......!"

The Underworld Blood Sea, somewhere in the deep sea—

Although it is also a deep sea, it is located in a relatively remote area.

In a Haitian wonder made up of thousands of blood corals, there is a deep cave that looks like a huge monster from a distance, crawling on the ground, swallowing endless water.

At this moment, a man was swimming among the corals and sneaking out of the sea cave.

It was Qin Feng who came specifically for hunting!

The voice of the brain girl came into Qin Feng's mind again-

"Little brother, you don't want to die, the danger is nine stars, you dare to come?"

In the brain girl's opinion, Qin Feng's true strength is only in the realm of the earth, even if he can deal with the Eight Lights Ghost King Beast, but don't forget, it is just a fake of a demon compound made by it!

And now, the Blood Taurus Barbarian King they are facing is a real demon king!

The gap in strength is not ordinarily large!

In particular, the Blood Taurus Barbarian King is still a top-notch existence at the level of the Demon King!

The special species of the Blood Sea of the Earth, a body of blood gold and brute blood can boil and burn in battle, intensifying the body of the barbarian bull demon to produce the power of the heavens, the power is infinite, and it can tear apart everything that stands in front of it with this brute force!

Pretty scary!

The key problem is that the Blood Taurus Barbarian King who has reached the realm of the Demon King can generally transform into a human form and begin to comprehend the laws of the Heavenly Dao, although this threshold is more difficult, but if it succeeds, it will not be far from the position of the Demon Emperor.

A demon king comparable to the early stage of the human monk Tiangang Realm!

And that's just the danger on the surface!

In addition, the potential unknown threat hidden in this strange Sea Cave Mansion is the most terrifying!

"Qin Feng is here to send him to death, do you know how to do it?!" There was a hint of anger in the voice of the brain girl, in her opinion, it was easy to find a good person, who could take it into the Yellow Spring, if it was hung here, all the plans would be over soon?

"Besides, it doesn't matter if you come to die, don't bring me with you!"

"Hey, talking to you, are you kid crazy?"

It's a pity that no matter how the brain girl persuades her, Qin Feng is indifferent!

In Qin Feng's opinion, the brain girl is so smart that she cleverly runs all the unknowns in the form of data in its brain, and such a result is reliable and unreliable!

Because judging from the results, no matter what, Qin Feng has no chance of winning!

The thick-skinned and thick-skinned Blood Taurus Barbarian King, unless it is killed with a single blow by means of thunderbolts, it will inevitably stimulate the brute blood of this beast to boil, and its strength will immediately skyrocket several times, and Qin Feng will definitely die!

"Qin Feng, what do you want to do?"

With doubts and puzzles, the Brain Girl only followed him silently, because she had no choice now...

Qin Feng stepped on a bloody crucian lion-headed beast, and was very careful to slowly approach the entrance of the cave, but before he reached the entrance of the cave, he was rushed out by a violent torrent.

With such a strong breath power, it seems that I really chose the right one!

patted the head of the bloody carp lion-headed beast, the latter nodded and immediately ran away, as fast as ever, a master of escape!

Qin Feng was speechless.

This guy looks very fierce, but he is born with a little timidity, it's a pity that this big lion head is a pity.

Smiling, Qin Feng sacrificed the Heaven and Earth Flood Flag, and after integrating it into his body, he walked towards the huge Blood Coral Cave and carefully touched it.

This cave is very large, countless coral stones, intertwined, exuding a faint light of blood, very strange and extremely hard!

And it's no wonder that—

The body of the blood manatee beast is relatively large among the sea beasts, this sea beast is shaped like a cow, with golden horns, and its strong limbs are all covered by blood-colored fish scales, and there is also a huge tail, the tail is shaped like a knife, and it is very long, which can be used as a weapon to chop the enemy!

If this big tail goes down, the opponent can be split in half directly!

However, with the Heaven and Earth Flood Banner in his body, he is not afraid that this demon king will find out, even if he finds out, what will he do? With his current comprehensive strength, even if he can't defeat the demon king, he still has the certainty of escaping.

However, Qin Feng's luck today seems to be good!

This blood manatee brute beast was actually asleep, and it was still in the beast form it used.

There was a reason why Qin Feng insisted on choosing this Wild Bull Demon King.

First, it had just advanced to the Demon Infant Stage, and its realm had not yet been completely stabilized, so it was relatively easy to deal with.

Second, what Qin Feng needed was the backbone of this Blood Golden Bull Barbarian King! This beast was a treasure all over its body, but because its big tendons were rope-shaped, the material was very suitable for refining a rope for ghosts and ugliness.

And the other two demon kings, in Qin Feng's opinion, are not as good as this brute bull's big tendons!

As for the potential nine-star danger, although Qin Feng was also a little jealous, for the sake of his precious apprentice, Xin Yiheng still came.

Let's take one step at a time, if it's not good, just slip away, anyway, when it comes to running for your life, you're no worse than anyone else!

Slowly diving into the depths of the cave, the undercurrent followed the breath of the Wild Bull Demon King, and it was a relatively regular tidal interval. Qin Feng repeated it several times, and finally went deeper.

In an open cavern, the situation was much better.

There is no water here, and it seems that this is where the wild bull demon king lives.

Didn't rush too deep, but found a hidden corner, hid it, and then sneaked out of the hole and took a rough look around.

After all, the Brain Girl's warning came first, so Qin Feng had to be a little more careful.

Overall, the environment here is very messy, with a lot of monsters and human bones.

It seems that this fierce bull is brutal by nature, and eats people of his own kind.

However, to Qin Feng's surprise, although the cave was in a mess, there was a faint aroma that instantly aroused Qin Feng's high vigilance!

Following the source of the aroma, in a large pile of bones, Qin Feng saw a very strange flower.

This flower is bone-white, and looks a little like a fairy lily, but it is definitely not! Because it is white and strange, white and forested, and all over the body exudes a trace of evil smell.

What kind of flower is this?

Although Qin Feng has a lot of knowledge, he has always been indifferent to things like this kind of evil grass.

But this thing appeared in the cave of the Blood Taurus Barbarian King, which is a bit of a joke.

Qin Feng narrowed his eyes and moved his gaze downward, in this large pile of chaotic bones, could it be that there was something good hidden in it? The netherworld purple pupil in his left eye opened, and Qin Feng was stunned to find that the bone essence all over the ground seemed to be passing, and the direction was completely towards the bottom of this evil bone flower, forming a very strangely shaped thing...
