After walking forward for several hundred meters, they finally saw a series of stairs leading upward.
This hall was hundreds of meters across, very spacious, with not a single stone pillar. The ceiling was adorned with mysterious murals: ferocious demon beasts and shirtless human experts locked in fierce battle. At the very end of the endless starry void, a pair of eyes gazed down upon it all in silence.
Nie Li looked up at the hall's ceiling. The demon beasts and human experts didn't catch his attention. What he noticed was that pair of eyes at the end of the starry expanse, which felt like the presence of a king among gods.
Even though it was just a mural, it gave Nie Li an immense pressure, making even his breathing feel a bit constricted.
Though it was only a pair of eyes, Nie Li knew they belonged to the Holy Emperor.
Some said the Holy Emperor wasn't that powerful. For countless millennia, countless mighty experts had challenged him, and many had come close to succeeding. Yet the Holy Emperor remained unharmed, while those challengers all vanished into nothingness.
The entire endless space-time was under the Holy Emperor's control.
No one could shake the Holy Emperor's absolute authority.
In his previous life, after the God Realm was destroyed, the Holy Emperor began slaughtering the powerful everywhere. The entire Dragon Ruins Realm was reduced to only a few hundred thousand survivors. Countless experts from all directions gathered to besiege the Holy Emperor, but they all perished. In his past life, Nie Li alone had broken through humanity's limits, possessing power akin to a god, even suppressing the Holy Emperor, but in the end, he still died at the Holy Emperor's hand.
If not for the Book of Time-Space Demon Spirit, Nie Li would have long since turned to ash.
"What's with those eyes? Just looking at them gives me a terrifying pressure, like a thousand tiny needles piercing my body,"
"You're talking about those eyes? That's a powerful Ancestral God!" Wuyazi smiled and said. "This Ancestral God is the ruler of the Holy Demon Realm. He is the supreme existence our demon race devoutly worships. Among your human race, no one can contend with this Ancestral God!"
Nie Li's eyebrows twitched slightly. The demon race might worship the Holy Emperor, but the Holy Emperor didn't necessarily care about them; they were merely his tools. Even if Nie Li pointed this out, the demon race's experts likely wouldn't believe him.
He wondered why the Phantom God Palace had such a mural.
Thinking of all the Holy Emperor had done in his past life, Nie Li clenched his fists, the veins on his arms bulging. Challenging the Holy Emperor's authority was no simple matter.
But for the next two hundred years, Nie Li could slowly lay his plans. He wouldn't challenge the Holy Emperor as hastily as he had in his previous life.
In the center of the main hall stood a crystal jade wall five or six meters tall. The jade was crystal clear, with illusions and colors flowing through it, dazzling and magnificent.
At the base of the crystal jade wall sat over a hundred experts—both human and demon. They sat cross-legged on the ground, staring intently at the jade wall before them, their expressions ones of deep contemplation.
"Why are there other people here?" Wuyazi was stunned. The experts on the ground were at the Heavenly Star, Heavenly Rotation, and even Dragon Path realms. For some reason, they were sitting before this crystal jade wall, lost in thought.
How had these people gotten here?
Nie Li speculated that these experts from various races had broken in during the previous time or even earlier. Once they entered, they had stayed here, wanting to comprehend the crystal jade wall before them.
This crystal jade wall was the Spirit Sky Wall. Only by deciphering it could one enter the true core of the Phantom God Palace!
