MTL - Back To the Past To Fall In Love - Chapter 1 back to high school

We have all heard the legends of great wizards, but do we know how those stories begin? Ardan Egobar, a young man living in a remote corner of the New Monarchy Empire, does not. He doesn't realize that this story is about him. Not yet...In a world where steam locomotives chug along iron rails, where massive airships hover in the skies, where in the cities you might encounter orcs in suits involved in organized crimes, dwarves with cigars controlling major banks, or elves strutting down fashionable boulevards, where humans have built vast nations on the brink of a world war, almost anything seems possible.Maybe, in such a world, even an ordinary young man, the last of the mountain hunters, might one day become the greatest wizard in history.

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.

In this world, there are Buddhas, Taos, demons, demons, and martial arts.

The martial arts system came from Buddhism, and there is a saying that all martial arts in the world came from Buddhism.

Meng Xing was a firewood chopping disciple of Zhenwu Sect of Xiuwu Sect.

After Hyundai Meng Xing crossed over, he started the road of system-assisted cultivation.

Since then, Meng Xing has become a god in the martial arts of the world.

……

Meng Xing met the leader of the Phoenix Fire Sect:

【1. Pretend not to see】

[Second, come forward to flatter, incarnate as a dog licking]

[Third, say to her, “Come here and serve your husband!”]

Meng Xing decisively chose the first option.

The other two are the rhythm of death.
