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? Or will he succumb into a conspiracy lurking within the country's borders?

PS. Cover not mine, I just found it on google.

Blue Star has entered the extraordinary era, everything is evolving, and monsters are rampant.

Humans awaken their star souls in evolution to fight against raging monsters.

Zhou Xuan, who was doing odd jobs in the Demon Town Tower, accidentally awakened to an unscientific sign-in system.

Sign in on the ancient desolate beast and gain the power of the wild. Sign in on the weed spirit, and the star soul evolves into the nine-leaf sword grass.

The thousand-year black turtle, the ten thousand-year sea king, the immortal true phoenix, and the sky-swallowing dragon have all become the targets of his registration.

There are countless monsters in the Demon Suppressing Tower, Zhou Xuan signed in silently, and if he was not careful, he would be invincible.
