A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

Lin Zheyu transmigrates into an ancient world and becomes a storyteller to make a living. After being robbed several times, he decides to learn martial arts for self-protection.However, during one of his conversations with his master, Lin learns that this world is home not only to martial artists but also to demons.

– The planet [Earth] has entered the abnormal state [Apocalypse].

– You have failed in saving the Earth. The Authority, [Vintage Clock (EX)] rewinds the world’s time.

For Yu Jitae, it was a message he had seen many times.

It was tiresome.

It would have been great had he died with everyone else.

But he couldn’t, for his authorities that made him the strongest existence, brought him back in time whenever he did.

And even with his strength, he couldn’t protect the broad earth against the maddened dragons.

– The world’s time will soon begin.

As the clock resumed ticking in the direction it should, his 7th iteration came to a start.

Fortunately, he finally had a gist.
