Ms. Tan Is The Real Boss - Chapter 1265 - : 1264 Magical Machine

Rudel Arses, the first born of one of the ‘Three Lords’ of the Courtois Kingdom, is from a corrupted family, but at 5 years old, he saw a dragon in the sky and his dark future as a villain changed. He was considered an idiot, but was that true? How would his effort to become a dragoon change the kingdom?

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 strongest doesn’t need cheats.

Haruka, a high schooler who spends his life as a “loner,” is suddenly summoned to another world with his classmates.

Noticing the god in front of him, Haruka was going to get cheat abilities by picking what he wanted from the skill list so that he could live in the other world――or so he thought, but the skills were first come, first serve.

All the cheat skills were taken by my classmates?!

After not being able to get any amazing skills, Haruka’s “loner” skill made him unable to join any parties. Even in another world, he’ll adventure in solitude.

Haruka, recognizing the crisis of his classmates, decided to secretly help them out while not relying on cheats. He’ll surpass cheats as he walks the path of the strongest――.

Let the curtains raise for the tale about the strongest loner’s attack on the different world!

This is the tale of an earthling, who transmigrated as a dying third-rate god but somehow rose through the ranks, gaining followers and eventually causing the Fourth Great Apocalypse.
