Xia Yun stood at the entrance of the town, glanced inside, and frowned slightly.

This town, without any breath of life, naturally there will be no human beings, and the town is extremely closed, surrounded by high walls, only the entrance in front of you, which is both the entrance and the exit, and it is not big, just four people passing side by side.

Xia Yun imagined what the Blood Spirit Realm was like.

As an evil immortal, the Blood Saint naturally needs a large number of human souls, and Xia Yun guessed that there should be a lot of human beings raised in the Blood Spirit Realm, just like raising Gu, the strongest person is likely to become a sacrifice on the path of the Blood Saint powerhouse.

However, at this moment, Xia Yun realized that he had underestimated the evil immortals, especially the blood saint and this immortal-level evil spirit.

Xia Yun estimated that this town could accommodate at least tens of thousands of people, and now, not to mention any human figures, there were not even corpses or bones.

"Be careful. ”

With that, Xia Yun took the first step, entered the town, and walked towards the center of the town.

Xia Jun and the others glanced at each other, understood what Xia Yun meant, and acted separately, which would be more efficient.

So, Xia Jun and Xia Yanran were in a group, Xia Hai and Xia Yang were in a group, and the rest of Xia Taohua, like Xia Yun, chose to act alone.

......

The center of the town.

The town was not big, and Xia Yun soon came to the square in the center, his brows furrowed even tighter.

It's more of an altar than a square.

Of course, Xia Yun knew that this was not really an altar, but just a symbolic building.

Along the way, Xia Yun carefully observed the buildings here, and with the help of the Blood Moon Divine Eyes, he saw everything in the buildings, and only then did he discover the meaning of the existence of this town-

Alchemy!

Obviously, most of the people who lived in this town were alchemists.

But no matter what, those alchemy furnaces have long been abandoned.

Based on this alone, Xia Yun estimated that this town had existed for at least 10,000 years.

Xia Yun also knew that the time flow rate of the Blood Spirit Realm was different from that of the outside world, and the time flow rate here would be much faster, at least dozens of times that of the outside world.

A month has passed in the Blood Spirit Realm, and only one day has passed in the outside world.

Xia Yun didn't delve into these questions, he just wanted to know what the elixir refined here was, and only in this way could he find the true meaning of the existence of this town.

Figuring this out, Xia Yun has more direction to hunt for treasures.

After all, their cognition of the Blood Spirit Realm was almost blank, and even those immortal cultivators were not clear.

None of the outsiders who entered the Blood Spirit Realm could get out alive.

After that, Xia Yun carefully studied the altar building in the center of the square.

"It should still be able to gather spirits. ”

Xia Yun quickly made a judgment, it turned out that this altar building still had such a wonderful use, allowing the surrounding spiritual energy to gather into this town.

"I don't know if there will be any mechanism ......"

Xia Yun smiled expectantly.

Next, he left the square, intending to walk around the town.

Less than an hour.

Xia Yun returned to the front of the altar building again, revealing a solemn expression.

Before, he simply thought that this altar building was only for gathering spirits, but now, he realized that gathering spirits was only incidental, and the real function was to gather souls, so that the surrounding souls gathered in the sky above this square.

Subconsciously, Xia Yun raised his head and narrowed his eyes, his eyes revealing a trace of doubt.

He knew that there must be something in the sky above the altar, but he just couldn't see it, even with the Blood Moon Divine Eyes.

The Blood Moon Divine Eye is not omnipotent, and Xia Yun has long been very clear about this.

Because of this, Xia Yun knew a little more that the existence that could avoid the Blood Moon Divine Eyes was extraordinary.

"Underground?"

Xia Yun suddenly thought of something, so he glanced at the ground, and then a trace of blood flame flashed in his right eye, and soon a smile appeared on his face.

He guessed right.

Below the altar, there was a dark space, and as for what was inside, Xia Yun couldn't be sure.

"Do you want to go down and have a look?"

Xia Yun thought deeply, he was still very cautious about the unknown.

"Did you find anything?"

Suddenly, Xia Jun's voice came from behind him.

"There's something underground. ”

Xia Yun said without looking back.

"Underground?"

Xia Jun came to Xia Yun's side and stepped on it twice, but found nothing.

"It's supposed to be a small spiritual realm. ”

Before the words fell, Xia Taohua appeared beside Xia Yun and said solemnly.

"You know?"

Xia Yun was a little surprised, if it weren't for the Blood Moon Divine Eyes, he really wouldn't have been able to find the dark space under the altar building.

"It was a mental space. ”

Xia Taohua explained.

"Mental space?"

Xia Yun was taken aback and said, "Materialization?"

"Hmm. ”

Xia Taohua nodded.

"Shhh

Xia Yun couldn't help but take a breath.

At this moment, he finally understood where the people in the town had gone.

Although he knew that the people of this town would definitely not survive, there must be bones.

And now, the bones of those people, if there is no accident, are in the spiritual space under the altar, also known as the spiritual black hole.

Only by absorbing enough souls will the spiritual black hole materialize.

"Not true. ”

Xia Yun muttered.

"Did you notice?"

Xia Taohua asked meaningfully.

"The number is not right. ”

Xia Yun nodded.

"I've checked, and the resident population here should not exceed 30,000. ”

Xia Taohua added meaningfully.

Xia Jun obviously didn't understand much, so he didn't open his mouth and listened quietly.

At this time, Xia Yanran, Xia Hai and Xia Yang also came to Xia Yun's side, and it was obvious that they had nothing to gain, not even anything of value.

So, they only hoped that Xia Yun could find out a little and not return empty-handed.

"Move this altar first. ”

Xia Yun suddenly proposed.

"Let's do it. ”

Before Xia Yun's words fell, Xia Hai and Xia Yang trotted over.

"Good. ”

Xia Yun did not object.

He knows how strong the Ocean Brother is, even Xia Hai, as an elder brother, although he is very small, but his strength is great, which is even more terrifying than his sturdy younger brother Xia Yang.

The short Xia Hai is infinitely powerful, while the tall Xia Yang is extremely fast.

For such a strange pair of twin brothers, Xia Yun was still a little curious.

Soon, Xia Hai pushed open the altar building with one hand.

As the altar left its original position, a piece of black soil appeared in front of Xia Yun and the others.

"It stinks!"

Xia Hai suddenly took a few steps back.

Xia Yang is no exception.

Although Xia Yun didn't do anything, he knew in his heart that the soil would turn black because of the blood of the year.

In this way, under the altar, all the people of the town are buried.

"Do you want to dig it out?"

Xia Yang asked a little expectantly.

"Will it be dangerous?"

Xia Taohua reminded very seriously.
