Red Envelope Group of the Three Realms - Chapter 3875 - -trump card

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?

…The truth is, I can see everything clearly.

Facing a meteor, I wished for a stable and respectable job and money to spend, only to become the lucky one physically carried away by the meteor.After drifting through chaos, I was reborn as Nezha.The good news is all my wishes came true, the bad news is the world is not right.Nezha, carrying fragments of the Creation Jade Slip and Chaos Pearl, doesn't want to follow the old path of becoming a tool for Taiyi to avert disasters, so he apprentices under Nuwa.What do you mean I killed Ao Bing? I don't know Ao Bing, you should ask someone else.What do you mean Yin Shou is tyrannical, he is just an enthusiast of cultivation.Stone Ji is a spirit born from rocks, naturally, she matches my expertise in mending the sky, so let her be my good friend (tool).Why do you say Zhao Gongming looks simple-minded? I think he looks very much like my brother-in-law.Let’s see how Nezha securely cultivates in the prehistoric world, defying fate and ascending the Great Dao.
