Marriage of the Di Daughter - Chapter 124.2: Part 2: Opponent

I transmigrated into a novel that I was reading.“But of all people, why did it have to be Kamon Vade?!”The problem here is this: the character I transmigrated as was a third-rate villain who appeared at the beginning of the original story, but after he had been accused of attacking the imperial princess, he disappeared and left the stage.“Haah, fine. The novel never said that I died anyway. So, I just need to somehow hold out and endure in the academy, right?”But…Maybe because I refused to exit the novel, ‘death’ keeps following me around.‘Motherfxxxer, this is like the fantasy novel version of Final Destination!’Damn it, I have to survive somehow.And I will! No matter what!

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.

When he came to his senses, Hirasawa Kazuki, a normal university student, found himself in possession of the body of a game’s character.

Moreover, it was Harold Stokes, the story’s most hated character who was even given the title 『King of trash』by the players. Myriads of landmines are just waiting for him to step on them, like death flags!

Will Harold be able to clear the survival route while avoiding the countless death flags in his way?!

Qinghe County master Gu Sheng died. She had a first class beauty, her name could move the world, but she still lost to the hands of a woman inferior to her. Gu Sheng was only able to understand that she was the antagonist of the heroine after her death, a cannon fodder.

In a pure white space, Gu Sheng was expressionless because of the transmigration.

System: “The heroine must change her fate, must fight against cannon fodder and the passerby to brush a sense of existence. As the master, you are their biggest stone in the way.”

Gu Sheng’s eyes flashed and made a peerless smile, “Then let me see who is the stumbling block that should be trampled and who is the final winner!”
