This sudden change caught everyone off guard.

"Aliens from outside the territory!"

The Wuji Immortal Emperor stared at the black mist, emphasizing each word, as if he wanted to carve these four words into his bones.

When these four words came out, General Yulong and Immortal Emperor Taixu were both shocked and looked at Immortal Emperor Wuji.

Even Ye Chen couldn't help but look up, with a hint of doubt in his eyes.

"I never thought that in this day and age, there are still people who know about the existence of alien races!"

A low, cold laugh was heard from the black fog, with a hint of mockery and surprise.

"You are the evil god sealed here by the ancient powers!"

The pupils of the Wuji Immortal Emperor suddenly shrank, as if he thought of something extremely terrible, and his voice trembled.

"Evil God?"

Ye Chen, Luo Qingcheng, Xiao Wuhen and others were all bewildered. They had never heard of any evil god.

"Evil God?!"

Taixu Immortal Emperor also suddenly remembered the records about the evil god in the ancient books of Wuji Immortal Art, and his face instantly became extremely solemn.

In ancient times, alien races from outside the domain joined forces with some demons to invade the fairy world and the demon world, triggering the ancient war.

The ancient war caused the fairy world to collapse and shatter, and all the powerful humans died in the battle.

This led to a gap in the inheritance and talent of the immortal and demon races, and it took countless epochs of recovery to achieve the current splendor.

"Humph, human race, despicable!"

The black fog rolled violently, and the evil god's voice was filled with anger and resentment.

"They couldn't defeat me, yet they united with some demons to seal me here!"

"If I break the seal, I will definitely exterminate the human race and eradicate the demons among the demons that are allied with the human race!"

The evil god's voice seemed to come from the Nine Nether Hell, carrying with it endless murderous and destructive intent.
