The black coffin at this moment, like a bottomless pit, can't be filled no matter how it is filled.

Su Mu's eyes were slightly condensed, looking at the scene of the black coffin absorbing blood and qi, it was difficult to calm down in his heart.

With so much blood and gas absorbed, he was curious to know what had happened to the contents of the coffin.

At this time, he tried to use his strength to open the coffin board. It's a pity that he was shocked and flew out directly, almost falling down.

Since the pitch-black coffin was "lived", its power has become more and more terrifying.

As the blood qi continued to be absorbed, the coffin continued to advance, and Su Mu followed closely behind, he wanted to know what the source of the blood qi was.

In the end, Su Mu got his wish.

In the center of the main hall, a corpse remains.

A huge corpse, as long as thirty-six zhang. This is a man, however, he is not an ordinary person, but a giant.

All the blood and qi emanated from that corpse.

That giant, I don't know how long it has been dead, its body is immortal, and its body still exudes deadly blood, which makes Su Mu stunned.

He couldn't have imagined that the source of blood and qi turned out to be corpses!

Originally, the entire hall was filled with deadly blood. However, as soon as the black coffin entered, the blood vapor disappeared at a speed visible to the naked eye.

All the blood and gas went into the "belly" of the black coffin.

The blood qi on the giant's corpse was dissipating rapidly, and because of the effect of those blood qi, the giant's corpse looked full and even glowing.

However, as the blood qi disappeared, the corpse of the giant dried up rapidly, changing faster and faster.

Su Mu looked at the giant corpse vigilantly, for fear of an accident.

Even death can produce such terrible blood, then when this giant is alive, his strength must be unimaginably strong.

Su Mu felt that even if he was a strong person in the Venerable Realm, he might not be able to do this kind of thing.

In Su Mu's shocked eyes, the huge corpse actually moved.

Suddenly, Su Mu was in a trance, and at the same time, his body retreated.

How is it possible that the dead body actually moved?

Su Mu distanced himself and looked at it carefully.

The giant's corpse really moved, the blood on the corpse was disappearing, and it looked angry and wanted to resist.

Under the effect of blood qi, the two big hands smashed heavily into the black coffin.

That power made Su Mu's heart frightened, even if he was far away, he could still feel the terrifying extent of it.

This kind of power, he had felt from those four Venerables not long ago.

In the face of this power, he didn't even have a chance to resist.

At the same time, Su Mu was a little worried in his heart, with such a terrifying power, could the black coffin hold up?

However, Su Mu was worried in vain.

In the face of the attack of the two big palms, the black coffin remained immovable, very calm, only caring about absorbing blood and qi, and did not care at all.

Bang!

Two terrible attacks slammed into the black coffin's body, the blood and qi rolled, and the surroundings shook violently, and many palaces began to collapse.

When the dust settled, Su Mu came out of a corner and hurriedly went to the main hall to investigate the situation.

The black coffin was nothing, still the same as before. No, to be precise, it's different, it has become more powerful after absorbing a large amount of blood qi.

The black coffin, as hard as it is, was able to withstand the attack of the giant's big palm.

And as the blood qi continued to drain, the aura emanating from the giant's corpse became weaker and weaker.

In the dark, Su Mu actually heard a few low roars, which actually came from the corpse of the giant.

Su Mu was shocked for a while, the corpse could not die, he could be regarded as an eye-opener.

The history of the Scarlet City is tens of thousands of years. In other words, this corpse is likely to have been dead for tens of thousands of years.

The more Su Mu thought about it, the more shocked he became, who is this giant?

The giant corpse struggled violently a few times, very violently. It's just that the black coffin is even more powerful than it, and suddenly it blooms with a strange light and flies on top of the giant's corpse.

Then, Su Mu only saw that the giant corpse was changing rapidly, and finally fell silent.

And as the blood and qi on it were all absorbed by the black coffin, the giant corpse finally transformed into a huge skeleton.

Even though all the blood qi was absorbed, the skeleton was still bright red, not white.

Click!

Su Mu waved the pig-killing knife in his hand and slashed down, and suddenly sparks arose, and he was shocked to a tingle.

Even if it's just a skeleton, it's still hard to cut off.

This further shows that the strength of this giant must have been quite strong during his lifetime.

Su Mu thought for a while, and then put away the giant's skeleton. This kind of skeleton is very valuable. Whether it is scientific research value or economic value, it is beyond imagination.

And the black coffin, after absorbing the blood qi, actually quieted down.

It automatically flew into Su Mu's genetic vault and remained motionless.

Su Mu stared at all this blankly, and it took a while to come back to his senses.

What is this, this black coffin still depends on him?

However, what reassured Su Mu was that the black coffin was not harmful to him, at least for now.

After putting away the giant's skeleton, Su Mu discovered that there was a cave in this hall.

In the center of the main hall, there is a large circular pit that leads vertically to the ground.

Just now, there was a giant corpse covering it, and the pit was invisible. Now, it's all revealed.

Is this the way out? Su Mu muttered to himself.

Unable to find another way out, Su Mu decided to give it a go.

He first checked it and found that the pit was very deep, giving people the feeling of bottomlessness.

The inside of the pit was quiet, and there was no smell of other creatures.

In an instant, Su Mu had a decision.

He jumped into the huge hole.

The walls of the cave are smooth, and I don't know how they were excavated.

Whew!

There was a sound of wind in my ears, caused by the rapid descent and the strong air current.

While falling, Su Mu was vigilant and ready for battle. As soon as he notices something is wrong, he flies back.

Luckily, during the descent it was calm and nothing out of the ordinary.

Thinking about it, under such a thick blood qi, it is difficult for ordinary creatures to survive.

Finally, when Su Mu was a little anxious, he finally came to the bottom of the cave.

"Hey, why is this place so familiar?"

Looking at the surrounding environment, Su Mu was surprised again.

The environment here is very similar to the one above, with a large number of palaces and, not far away, a river of blood.

"What's going on, is there a hallucination?" Su Mu was very puzzled and full of incomprehension.

What surprised Su Mu even more was that he actually saw people.

It's a living person!

There were three people in total, three adventurers, Su Mu and they entered the Scarlet City together, but when they crossed the bridge, everyone separated.

How could they be here?
