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?

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

Yun Lintian, a man from modern Earth, found himself in a cliche situation that was all too familiar to him in novels: Being transmigrated! He had arrived in a magical cultivation-oriented world called the Azure World.

Unlike the other protagonists in various novels he had read before, Yun Lintian was left without any cheat device. Pill Emperor inheritance? Super God-like physique? He had nothing!

Did the God of Transmigration really leave him with nothing? How was he going to live in the world that strong preying on the weak?

Watch the journey of Yun Lintian in the foreign world as he grew up in power ranking along with his precious all-female sect!
