MTL - The City’s Almighty System - Chapter 3380 Luan Beitianxian

After his transmigration to the cultivation world, Shen Tian discovers that he can see the fortuitous opportunities and their providence haloes of others.

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?

Read at your own risk.I was the strongest player in the world—until they betrayed me.When I woke up, I wasn’t a player anymore. I was just an NPC.

I evolve beyond the system’s control, beyond the limits of this world.They thought I was nothing.They thought they could use me, farm me, erase me.Now, I am the final boss—and I will make them suffer.On the battlefield, and in my bed.They will submit. One way or another.
