MTL - Peerless White Emperor - Chapter 8 Unexpected danger

Seven billion humans living on the Earth time-traveled together after they had woken up one morning. They all heard a synthesized female voice.

Jin Rou, the youngest Celestial King, was being restricted to go outside by his father for some reasons. Thus, Jin Rou was fed up.

And so, he made his ‘Grand Plan’ of running away.

You thought being reincarnated as an extra-side character was bad? Imagine being thrown into the body of a villain who is disowned by his own family and discarded by the author.

There was once an immortal cultivator fighting for the fate of human beings. Unfortunately, he failed that time; but fortunately got another chance as he was reborn once more as a human, on the earth of 5,000 years ago. With a second chance, he not only would embark on the road of saving all mankind, but also would retrieve his human nature on the new journey that would last for 5,000 years.
