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 Qingyin, the master of fortune-telling, didn’t succeed in the Thunder Tribulation when she tried to ascend. When she woke up again, she became a high school student. Lin Qingyin, who was not afraid of Thunder Tribulation, looked at the thick test paper in front of her and shivered. Only a thousand years had passed, how could the world become so scary!
