Hello, Mr. Major General - Chapter 2173

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.

The dead broke small streamer Zong Qi received a random message one day.

Zong Qi: ? tr*sh commercial, deleted

That night, he got pulled onto the set of a horror film and was informed that if he didn’t shoot it… He’ll die.

He was lucky that the actors were all working as hard as they could, and the director only needed to stand around and watch the show.

But because he had been given way too much, Zong Qi didn’t hesitate at all before making his own changes.

Under his false identity was an ‘evil mastermind’ that fought with the actors on everything.

The immoral things he’s done on set include but aren’t limited to–

Personally putting makeup on the ghost, teaching actors how to mess and change the script, switching ‘sides’ at crucial times…

People as arrogant as him usually don’t have good endings when their identities were revealed.

What Zong Qi didn’t expect was that instead of the actors joining up for revenge, an unlucky bastard’s whose plans had been spoilt by him countless times appeared instead.

The man took off his glasses, revealing a pair of closed eyes, his face beautiful and cold.

The brush dipped in paint hooked past the young man’s neck, full of danger.

“You dirtied my brush.”

He smirked, drawling, “As punishment, I’ll dirty you.”
