In an underground world, at this moment, a young man in white is lying on a wooden bed, and there is a beautiful girl dozing in the room.

Obviously, it is waiting for the youth to wake up.

But after five hours, there was still no sign of waking up.

This made the other party very confused, and they all began to doze off.

Just when the girl was asleep.

The young man on the bed moved his hands, but he did not wake up.

At this moment, the colorful hibiscus brain emitted a green light, starting from the brain and surging towards the whole body.

When everything stopped, the injuries in the young man's body finally recovered.

Not only that, but under the automatic operation of the Hundred Refining Divine Formula, the bones and the body began to heal automatically.

Almost seven hours later.

The young man in white opened his eyes, looked at the sky, and found that there were planks, apparently in a house.

"Where am I?"

Ye Fei muttered to himself.

Yes, the young man in white is none other than Ye Fei.

Before, he forcibly opened the hidden realm and burst out the power of the six hidden realms, causing him to suffer a lot of injuries.

Finally fainted and fell to the ground.

Ye Fei didn't think much about it and got up from the bed.

Looking at the three-layer quilt and the wooden bed, Ye Fei was puzzled.

Then I saw a woman in a flower dress sleeping.

"Martial Venerable Realm powerhouse, so young."

Ye Fei couldn't believe it, he was almost twelve or thirteen years old, since he had the strength of Wuzun.

It's hard to imagine.

Just as Ye Fei was looking at the other party, the girl suddenly sensed something and suddenly opened her eyes.

Sitting up from the chair, his eyes looked at Ye Fei's bed, but he happened to see a pair of black and white eyes, staring at him.

This scene, where did the other party experience it, and couldn't help but blush slightly.

"You're awake."

Although her face was red, Ye Fei was an injured person, so she still spoke hard.

"Where is this, how did I end up here?"

"Snake's den."

"What??"

When Ye Fei heard this, he almost didn't fall down.

Then Ye Fei learned from the other party.

In this snake den, there are only two humans.

Among them, she is one of them, and at the same time, Ye Fei also knows that the other party's name is Lan Feng, who grew up with Grandpa Snake.

After almost understanding it clearly, Ye Fei ran the exercises and found that he had recovered.

And the body is completely stable.

Not only that, Lan Feng also took Ye Fei to see Grandpa Snake.

Soon, Ye Fei passed through a criss-crossing passage and appeared in a cave house.

There is no strong aura in it, but it has a very old feeling.

"Grandpa, I'll bring you too."

"Feng'er, you go out first, I'll talk to this little friend."

The voice fell, and an old man in a black robe appeared in front of Ye Fei's eyes.

The long beard, almost a meter long, and the eyes are like two pools of stagnant water, and they are black, which makes it feel very dangerous at a glance.

"Thank you seniors for helping, I don't know what seniors want to know."

Ye Fei saluted very calmly.

Hearing Ye Fei's words, the other party smiled slightly.

Then he pointed to a chair and asked Ye Fei to sit down and said.

"Do you really want to know what kind of place this is, or rather, want to know why there is such a terrifying existence in the demon race."

The old man asked several Ye Fei questions in a row.

Ye Fei really wanted to know.

Because he couldn't understand why such a terrifying demon appeared in this so-called testing ground.

It's all about torturing them, where is the testing ground.

"Please also tell the seniors one or two."

Soon, the other party told Ye Fei that this so-called trial ground has a total of ten entrances, that is, ten empires.

Each entrance is opened at a fixed time.

Only the entrance to the Hongwu Empire is opened once in fifty years.

Needless to say, there are dangers.

Whether it is a demon clan, a bone clan, or a spirit beast, if you live in one place for a long time, your strength will definitely become stronger with the years.

As for the demon powerhouse, it was deliberately put into it by the Holy Land.

One is to temper the disciples of the trial ground.

The second is to suppress the demons.

As for whether the disciple can survive, for the Holy Land, it is best to survive, and if he can't survive, he can't hope for others.

As for the snake's den, he didn't know what it was.

He only knew that it had existed since he appeared, and he didn't know what was in it, and why it existed.

This shocked Ye Fei very much.

The other party didn't know it, which was incredible.

"Senpai, then why am I here, am I not in the proving ground?"

"This is the snake's den, and it was the jade pendant on your body that brought you here."

"What......"

Ye Fei was directly stunned, completely unable to believe it.

Everything will be related to his dragon-shaped jade pendant.

But think about it, it's not uncommon to be able to save yourself before and bring yourself to the snake's den.

"Xiaoyou, you have cultivated the Ten Thousand Dragons Formula, if I know well, if you want to cultivate the first layer of the Ten Thousand Dragons Recipe successfully, you must have a strong physical body tempering, am I right."

The old man looked at Ye Fei calmly.

Ye Fei frowned, not knowing what he was thinking.

"If you want to cultivate the Ten Thousand Dragons Technique, you have a place where you can recommend you to try it, and whether you can succeed in cultivation depends on your chance."

The old man said, and with a wave of his hand, a secret door opened from the wall behind the other party.

Then a cold breath came to his face.

The old man didn't say much, and let Ye Fei enter it.

Ye Fei sensed it and found that it was all dead things, so he stepped into it.

The old man also followed into it, and what was imprinted in front of him was a corpse.

There were white, red, and golden bones.

Looking at the scene, Ye Fei frowned.

A little excited, because these golden bones, for him, are cultivation resources.

You can use the Hundred Refining Divine Recipe to absorb and refine the physical body.

"Xiaoyou, this is the snake mound, that is, the place where the strong people of the Red Phosphorus Snake line sit."

"You slowly cultivate in it, and I won't bother you."

The old man spoke, and then disappeared.

The passage was also closed.

"No, there are so many bones here, why aren't there any members of the bone-forming clan."

"But the dead air here is indeed a bit strong, and for me, it can be described as a great supplement."

Ye Fei muttered to himself.

As he spoke, he came to a skeleton.

"This breath, could it be that it is beyond the bones left by the powerhouses of the Martial Venerable Realm."

Ye Fei was a little shocked, he didn't expect it.

The bones in the snake mound are so strong.

For Ye Fei, these things are treasures.

"It doesn't matter if you are beyond the existence of Wuzun, you will absorb the dead qi first."

Ye Fei said secretly, and began to sit cross-legged.

At the same time, the necromancy was running, and the surrounding dead qi was surging wildly.

If it weren't for the Devouring Sword Codex, it would have been a bit difficult to devour these dead qis.

Even if the devouring speed of the Necromancy Technique is very slow.

Fortunately, after Ye Fei's Devouring Sword Dictionary was devoured, it could be absorbed by the Necromantic Technique.

Time flickered, and an hour passed.

The surrounding dead air almost disappeared.

Ye Fei also opened his eyes, feeling the dead qi in the chaotic dantian, Ye Fei was very satisfied.

"In such an hour, it will break through to two meters and one, and if this speed is maintained, the death qi will definitely become stronger and stronger, but why, the chaotic dantian is chaos, why is the death qi not fused, could it be that if you want to fuse with blood and aura, you have to fuse the dead qi."

Ye Fei was a little puzzled, he knew very well about the death qi, now it was because of the Chaos Dantian, so it could exist in the Dantian, but it was not fused into the Chaos Dantian.

This is indeed a bit confusing.
