The Unstoppable Emperor Yan

The natural high-dimensional mental power radiating from the conqueror suppressed the entire Milky Way Galaxy.

Even the distant Taiwei Hua Nebula felt his terrifying presence.

As one of the emperors from the Grey Emperor's timeline, his return to this timeline without the Grey Emperor could not be called invincible, but at least in the entire local galaxy cluster, he could not possibly have any opponents.

Let alone that the historical progress here was more than two thousand years slower than on the Grey Emperor's side; even if it were faster, the Milky Way would still look like this weak, slowly developing entity.

It was the Grey Emperor who had made the Milky Way great. Otherwise, another ten hundred thousand or million years down the line, the Milky Way would remain an unremarkable existence in the wider universe.

It was also the Grey Emperor who had taken his soul away from this timeline, combined it with the body of Xuanzun, and endowed it with a force and realm sufficient to transcend dimensions, making him one of the great emperor clones.

Now, owing to the Heavenly Dao Nirvana on the other side, he temporarily had no need for self-sacrifice, and the Grey Emperor had simply sent him back to this timeline in a return of glory and wealth.

When he left, Zeta was a slave, and the Milky Way was in the Star Alliance era of contention among ten thousand races.

Now upon his return, Zeta remained enslaved. Unable to bear the sight of it—having witnessed the brilliance of the Zeta Civilization on the other side—he wanted to emulate his counterpart from that alternate timeline and lead the Zeta people to forge great achievements as well.

However, the Milky Way had also nurtured a great being: Emperor Yan.
