The Absolute Immortal Sword is indeed extremely sharp. Although the material of the metal plane is not simple, and the forbidden patterns on the plane are not simple either, it cannot withstand the absolute sharpness of the Absolute Immortal Sword.
Not long after, Su Bai cut a crack, and the light from the outside world shined through the crack, illuminating the world under the metal plane.
Wherever the light shines, a strange aura emanates.
Su Bai jumped directly from the gap and came to the world under the metal plane.
Su Bai showed an extremely shocked expression.
Under this metal plane, there is an extremely huge tower-shaped altar!
The small copper-colored tower that I saw on the lake before is actually the top of the altar!
This altar is at least 70 million miles high and has nine thousand floors.
Each floor is covered with skulls. These skulls are actually the skulls of mortals. They are blessed with special power and have not been damaged by the wash of time and years.
Countless skulls are shaking gently. This scene is so weird.
The entire altar is so huge that if it were completely exposed, it would occupy almost three-quarters of the area of the imperial city!
How could Su Bai not be shocked that there was such a existence hidden under the entire imperial city?
Moreover, the refining method of this altar is very unusual, and it is not like something that the Holy Lord can do.
Altar, connected to the earth.
How far it reaches, Su Bai cannot detect it, because the strength of this clone's spiritual thoughts is limited.
This altar is so huge that it is covered with ancient scriptures.
At the same time, Su Bai felt a familiar feeling, as if there was a certain aura that he had noticed before.
"It's the Yin-Yang Fish Picture Scroll!" Su Bai quickly remembered.
There are some similarities between the aura of this altar and the yin-yang fish scroll that Xu Jie was carving that he saw in the Blood Sea Temple.
"Is it a coincidence, or is this altar itself related to the Ruins Ring?"
"Why is there such an altar that is related to the Ruins Ring under the ground of a sacred city in the end of the world? What is this altar used for?"
Su Bai didn't understand very much.
Moreover, there are also witchcraft characters on the altar. This may be related to the witchcraft clan and has a lot to do with what Xujie is planning!
Thinking of this, Su Bai wanted to destroy the altar. Although the material of the altar was special, it was not difficult for Su Bai to do this with the Immortal Sword in hand.
The only concern is that if the altar is destroyed, will it alert others?
Su Bai hasn't figured out what Xu Jie's plan is yet.
It would probably not be a wise move to alert the enemy before this happens and expose oneself.
In the end, Su Bai did not do this, but stayed in this underground world for a long time, memorizing all the words in his heart.
When he had the chance, he would hand over these words to Senior Shenxiao, maybe the latter could figure out some clues.
All in all, this altar is definitely not that simple.
With the cultivation level of Emperor Hongwu, he was unable to come to this underground world, and he probably didn't know that such an altar existed here.
Therefore, he did not know the reason why the royal family member Manfu died mysteriously in this villa.
Their souls and blood were probably swallowed up by this altar!
After writing down all the words, Su Bai left here.
During the few days he stayed in this underground world, Mingcheng had already married the Ninth Princess Lingwei, and the entire imperial city was immersed in an atmosphere of joy.
Not only that, a spiritual energy that was ten times more powerful than before covered the entire imperial city.
It was Emperor Hongwu who, in order to celebrate the wedding of his daughter and Mingcheng, specially released the spiritual energy of his ancestral land, covering the entire imperial city for a month.
During this period, as long as you are in the imperial city, you can use these spiritual energies to practice.
It should be noted that spiritual energy is almost the most precious thing in the world!
Not to mention how happy Mingcheng was to get married to his beloved, the only thing that made him feel a little regretful was that Su Bai could not come to attend his grand ceremony.
Or maybe Su Bai is here, but he doesn't know it?
A few days after the ceremony, Mingcheng and Lingwei came to the restaurant together and found Mingya.
"Xiaoya, is that senior still there?" Mingcheng asked.
Mingya shook her head, "I don't know either, I haven't seen Master for a few days!"
"Brother, don't forget to promise your master!" Mingya said suddenly.
Mingcheng nodded solemnly.
"Of course I remember!" Mingcheng said.
Lingwei was slightly confused, "What are you talking about?"
Mingcheng said: "These things... I'm afraid I can't tell you."
Lingwei frowned.
Mingya immediately grabbed Lingwei's hand and said, "Sister-in-law, don't blame my brother. Some things are too involved, and my brother didn't let you know about it just to protect you!"
Lingwei nodded.
Su Bai has returned from the underground world now.
Of course, Su Bai was also concerned about things in the underground world, but he couldn't figure out the purpose of those altars so quickly.
The most urgent task now is to meet the elder of the Wu clan and clarify Su Bai's doubts about the Wu clan.
Su Bai's figure appeared in the restaurant like a ghost. They didn't find it strange. They were just slightly startled and immediately saluted Su Bai.
Su Bai nodded slightly and looked at Mingcheng.
"Mingcheng, what did you promise me?" Su Bai looked at Mingcheng immediately.
Mingcheng hurriedly cupped his fists towards Su Bai and said, "Senior, I have contacted the clan elder and he agreed that I can take you to meet him."
Su Bai nodded slightly.
"Very good, what time?"
"That's it now!"
With that said, Mingcheng looked at Lingwei and said: "Weier, you go back to the palace first, I have to fulfill the promise I made with my senior."
Hearing this, Lingwei asked: "Is there any danger in this matter?"
Lingwei glanced at Su Bai again.
Su Bai said: "Don't worry, at least there won't be any danger in this matter."
Lingwei nodded.
Su Bai took Mingcheng and Mingya away together. Mingcheng had already given Su Bai the exact coordinates.
It's actually not within the territory of the Hongwu Dynasty, but with Su Bai's cultivation level, it only takes less than half a day to arrive.
The coordinate location is in a desolate mountain.
There are almost no human beings here, and only a lot of wild beasts and vicious beasts survive. Surprisingly, the cultivation level of these wild beasts and vicious beasts is actually not low.
The highest one can even reach the level of the Holy Lord.
However, this place is desolate, and few people will come close to it, so they will not know that there is actually an old man living in these mountains.
All the wild beasts and ferocious beasts in these mountains are under the control of this old man.
