The demon walked out of the ancient flags, then opened its big mouth and crazily devoured the cold air that spewed out from the ancient well.
On the side, Yu Xingwan couldn't help but take a few steps back, with a look of fear on her face.
In her opinion, this demon is too evil and too powerful!
The intensity of the demon's aura has reached a level that is difficult for her to understand.
Of course, she couldn't understand that it must be extraordinary.
Moreover, the terrifying demonic energy emanating from the nightmare always gave her the feeling that this monster might choose someone to eat at any time!
Yu Xingwan was shocked inside.
The Su Bai in front of her was not only unfathomable in strength, the monster he raised was also terrifying!
Yu Xingwan instantly defined Su Bai as an extremely terrifying person who must not be slighted or offended in any way.
The demon swallows the cold air, and the cold air will not spread to places outside the Fengyue Tower.
Su Bai continued to tear apart the restriction, and then escaped into it through the torn cracks.
Mingya followed closely and jumped in with the little girl.
Yu Xingwan hesitated.
Because her intuition told her that this ancient well is definitely a very dangerous place!
But staying here, with that demon, made her feel uneasy, so after hesitating for a moment, she jumped in too.
Under the ancient well is a huge underground world, which is almost the same as the world under the murderous house in Hongwu Imperial City!
The same vastness, the same extreme darkness, the same, there is a huge altar, the altar is like a giant tower, the top of the tower is connected to the well mouth.
The aura of this altar is slightly stronger than the one under the Hongwu Imperial City!
Mortal skulls were hung around the altar, and the aura of resentment was astonishing.
This was not the first time for both Su Bai and Mingya to see such a scene, so their moods were not too disturbed.
"As expected, that context diagram is indeed the context diagram for the layout of this altar. There is also such a huge underground world under Tianyuan City, and there is also such an altar."
Hearing Su Bai's words, Yu Xingwan looked surprised.
"My lord, there is also... such an underground world and such an altar. Is there more than one?" Yu Xingwan asked in surprise.
Su Bai nodded, "There's more than one, at least for now, there are two that I've seen."
"Furthermore, according to my speculation, there are many such underground worlds and altars under the eighteen continents of the world. You...what are you doing?"
While Su Bai was talking, he found that Yu Xingwan seemed to be under some kind of spell, and walked straight towards the altar, her eyes a little dull.
But with her cultivation, she couldn't resist the power of resentment released from the altar, and soon her skin began to fester!
Su Bai frowned slightly and pulled his sleeve back through the air.
After returning to Su Bai's side, under the influence of Su Bai's infinite power, Yu Xingwan's skin and flesh, which had been ulcerated a lot, quickly recovered and regained their luster.
Yu Xingwan's expression also regained consciousness, and she felt like she was surviving a disaster.
"What happened to you just now?" Su Bai asked.
Yu Xingwan shook her head, "I don't know, it seems like she is out of control and is being pushed away by a force..."
She looked up again at the altar in front of her, with a look of deep fear in her eyes, and then she said something that surprised even Su Bai.
"I've seen such an altar, it's very similar!"
Hearing this, Su Bai paused for a moment, then immediately said: "You have seen such an altar, where have you seen it?"
Yu Xingwan said: "In a ruined ancient world, everything in the ancient world was destroyed and destroyed. Only one altar remained, which was relatively intact. It was very similar to the previous one, with countless skulls hanging on it, and the aura of resentment.
Terribly strong!"
"The ruined ancient world... It's hard for me to have an intuitive feeling when you describe it like this. I wonder if you can let me search for souls?" Su Bai said.
Hearing this, Yu Xingwan's face suddenly showed a look of resistance.
She naturally has her own secrets, and she is still a woman. If Su Bai can search her soul so easily, wouldn't it mean that no secret can be hidden from Su Bai?
However, Su Bai is very powerful, can she refuse?
Su Bai saw what he was thinking, and then said: "You can separate out that part of the memory about the altar. I will only look at this part of the memory, and the rest will not be touched at all."
Yu Xingwan knew that she had no right to refuse in front of an extraordinary saint, so she had no choice but to believe in Su Bai's character.
She peeled off that part of her memory and stored it alone in the sea of consciousness.
Su Bai pointed at the center of his eyebrows, his spiritual power poured into the sea of consciousness, and he quickly found this part of the memory.
And the pictures in his memory appeared in front of Su Bai as if they were real.
A ruined ancient world...
They are countless celestial bodies with different rules, floating in the starry sky. They are all products after the destruction of the ancient world. Some celestial bodies even retain the outlines of various buildings.
However, it was a dead silence, with no life at all.
And on top of one of the most complete and largest celestial bodies, there is such an altar, with countless skulls hanging and strung together into wind chimes, and the aura of resentment is terrifying.
The destruction of this ancient world seems to be closely related to this altar.
"This altar is..."
Su Bai frowned slightly.
"This ancient world is at least an ancient world with a holy master sitting at its limit. Under the chaotic starry sky, such ancient worlds are extremely rare."
"His destruction is related to this altar, and this altar is definitely not a product of this ancient world."
From this part of Yu Xingwan's memory, Su Bai has already seen many problems.
With the level of monastic civilization in the ancient world, they could not build such an altar. Many of the patterns of laws on the altar required extraordinary cultivation to be carved.
In the altar, countless resentments and blood energy had been accumulated, probably from the sacrifice of an entire ancient world's creatures.
But most of the blood and resentment were drained away, leaving only traces of an altar. This is why Yu Xingwan once came into contact with this altar and was able to escape unscathed.
But the altar must have had a big impact on her at that time, and it also caused her memory to become very blurry...
If she hadn't been affected by this altar again today, her memory might not be able to be recovered.
"The function of the altar is to sacrifice the common people in order to accumulate resentment and blood. The altar in her memory is more like a test subject."
Su Bai's mental power withdrew from Yu Xing's sea of consciousness, and then looked at the altar in front of him, his expression became much more complicated.
"And this altar is more like a finished product, or a perfected existence!"
A terrible thought suddenly appeared in Su Bai's mind.
