"The secret of the Holy Land?"
Su Chen blushed with shame. He thought the Black Phoenix wanted to ask for his favor again.
"What secret?
Why didn't you tell me when you met Chan Guangming? "
The Black Phoenix whispered, "This is a little unusual. Of course, I have to tell you first, and … Forget it, it's hard to explain. Anyway, you'll find out later."
Su Chen thought of something and said, "Take me there."
The Black Phoenix quickly took Su Chen to the depths of the cave. Suddenly, a heatwave hit them, and an ordinary magma pool appeared in front of them.
There were many active volcanoes nearby, so it was not strange for magma to appear.
"Come out!"
The Black Phoenix suddenly called out.
The Emperor Fire Kylin's huge head suddenly popped out of the magma pool and opened its bloody mouth.
Then the Black Phoenix pulled Su Chen into the mouth of the Emperor Fire Kylin.
"Uh … What's this for?"
"Master, don't worry. You'll know later."
You've learned to keep me guessing?
The Emperor Fire Kylin suddenly closed its mouth and sank into the magma.
Su Chen could vaguely sense that the Emperor Fire Kylin was swimming toward the depths of the magma pool.
After about an hour, they seemed to have reached their destination.
The Emperor Fire Kylin opened its mouth again. The Black Phoenix carefully activated her pneuma to protect Su Chen's body.
Su Chen walked out and found a huge bubble in front of him.
There was a vacuum inside the bubble, where a pure white palace floated. It was completely made of top-grade jade and looked very noble.
"What's this?"
It was indeed strange that such a strange palace was hidden under the Holy Land.
"The Emperor Fire Kylin happened to find it when it was bathing in the magma. I went in to investigate once and found something terrible inside."
Something terrible?
Su Chen followed the Black Phoenix into the bubble.
As soon as he entered, Su Chen felt a strong burning sensation all over his body.
It was a vacuum environment without any flames, but the temperature was terrifyingly high. If not for the protection of the Black Phoenix, a powerhouse in the No Doubts Tribulation, Su Chen would have been burned to ashes if he came in alone.
"Master, be careful. This place is filled with the purest holy fire. This kind of flame has no form, but it can even burn the void. The best way is to smear some of the Emperor Fire Qilin's saliva on your body. It can effectively resist the power of the holy fire." The Black Phoenix said, making the Emperor Fire Qilin stick out its huge tongue, licking Su Chen's body.
Su Chen looked at his wet body and felt helpless.
Still, the effect was quite good. The Imperial Fire Kirin's saliva formed a special protective layer, preventing the temperature of the outside world from reaching Su Chen.
Without hesitation, Su Chen immediately flew towards the palace.
The size of the palace was very large, as if it was not built for people to live in. Just the two white jade pillars at the entrance were over a hundred meters tall.
After walking in, Su Chen found that the palace was empty. There was nothing out of the ordinary.
"Where is the terrifying thing you were talking about?"
"Master, don't be impatient."
The Black Phoenix carefully checked the surroundings, then led Su Chen into the palace. After many twists and turns, they found a huge and empty room.
The room was very well-furnished, but the size of everything was hundreds of times larger than what a normal person would use. The white jade bed was over thirty meters tall, and it could probably fit over a hundred people at the same time.
"Could this be the palace of the giants?"
"I don't know. This palace is not the main point. The main point is what's below."
The Black Phoenix pulled Su Chen to the bottom of the bed.
There was a cracked white jade floor tile, and the gap was about the width of a person. It was just enough for them to crawl in.
"Master, follow me."
With that, the Black Phoenix crawled into the gap.
Su Chen calmed himself down and immediately followed.
All the way down, through the thick ground, Su Chen saw that there seemed to be a huge secret room below.
The two of them slowly floated in.
Looking at the things around, Su Chen couldn't help but frown. Even his breathing became a little erratic.
In this sealed secret room, there were over a hundred square cauldrons carved from white jade placed neatly.
Every square cauldron was filled with a milky white liquid.
There were many objects that looked like giant walnuts floating in it.
No … not walnuts, brains!
"These are …"
Su Chen was too shocked and didn't know what to say for a moment.
The Black Phoenix said, "From the shape, these are not human brains, but the brains of demon experts. The sea of consciousness of each brain is intact. They were all demon experts at the Reincarnation Realm when they were alive. There are a total of one hundred square cauldrons. Sixty-three of them contain brains, and the remaining thirty-seven are empty."
"Are you sure this is the work of the Sacred Ground?"
"These brains have existed for a long time, but also for a short time. The oldest one has been soaked in water for tens of thousands of years. This is the foot of the Holy Land. Apart from the Holy Land, I really can't think of anyone else who has the ability to capture so many demon experts and store their brains here."
"What's the reason?"
Su Chen frowned. He really couldn't think of a reason for the Sacred Ground to do this.
If it was purely to punish the demons, killing them would obviously be the best result. Not to mention that it would bring trouble, there would also be hidden dangers.
Could it be to imprison these demon experts?
These brains did seem to have a certain amount of life force. This also meant that most of these demon experts were still alive. It was just that they only had their brains and sea of consciousness left. They barely preserved their souls and were in a state worse than death.
This method of imprisonment and punishment was indeed very effective. However, with the Sacred Ground's prestige, it was hard to imagine that they would do such a thing.
The Black Phoenix said, "According to my guess, the Sacred Ground is probably trying to study the ancient secrets!"
Su Chen asked, "What is the ancient secrets?"
He suddenly recalled that Chan Guangming and Wu Mingkong's purpose of going to the Immemorial Island seemed to be to find some clues.
The Black Phoenix said, "Master, do you know that tens of thousands of years ago, before the Three Purities Sect spread the light of cultivation to the Xuanyuan Continent, the Xuanyuan Continent was completely under the control of the demon race?"
Su Chen nodded. "I've heard of it."
"This is not a secret. Most people have heard of it, but they only know part of it. I once heard from my father that the demon race was actually not the ruler of the Xuanyuan Continent. They were just prisoners bound to the Xuanyuan Continent. At that time, the Xuanyuan Continent was a huge cage!"
"There was such a thing?"
The Black Phoenix continued, "A million years ago, in the ancient times, the immortals built twelve Tower of Babel on the Xuanyuan Continent. It was not to connect immortals to mortals, but to exile countless prisoners here. There was also a huge secret hidden in it. This is the ancient secrets. Legend has it that whoever can crack this secret will be qualified to escape from the sea of suffering and ascend."
