MTL - Don’t You Like Me - Chapter 44

A young man named Alexander Ashbourne is looking for a job to support his studies. He applies to work as a waiter at a restaurant. The next day on his 18th birthday, a system appears that generates money simply by idling. This system also allows him to trade with beings from other worlds or even visit their realms. Watch as Alexander rises to fame across all the realms.[DeathlessOne: I just spotted this mortal, 'AlexanderTheGrate,' trying to trade his drink called Mountain Dew. I'm thinking of offering my Flame Sword for it.][ShadowEternal: Wait, what’s a Mountain Dew?][TimelessWanderer: Are you seriously considering trading your Emperor-grade sword for a mere drink?][DeathlessOne: It’s not just any drink. The taste is out of this world, It's even better than the heavenly wine.][ShadowEternal: {...}][TimelessWanderer: {...}][Everyone in the chat: {...}][RichNigga: You know what, I’m in. I’ll trade my Gold Deluxe Armor just to see if this Mountain Dew is worth all the hype.]

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?

In his last life, Xue Yan had been a powerful minister all his life. When he returned to seven years old, he didn’t want to be any more. In the same way, he has all the power in the world, but his family cannot end well.

Unexpectedly, his father suddenly picked up a baby girl, saying that he had raised him and would be his daughter-in-law.

The daughter-in-law is all good, but not good at all. She can’t be allowed to sneak out alone.

Otherwise, she will bring you back a great general this time, and next time she will bring you a different surnamed king, and even the queen mother of the dynasty will be rescued…

Not long after, I’ll bring you a little emperor again…

Jiang Yue, the supreme commander of Area A in the end of the world, actually dressed in ancient times and became a three-and-a-half-year-old girl.

No matter how she lived her life, it was just that her future husband didn’t know what was going on. Every time she kindly rescued a person, he would be disgraced.
