The Male Protagonist of My Graduation Thesis Went Crazy

Shen Yuewei accidentally traveled to the world of the male protagonist of her thesis, and she was completely confused. She only knew that the male protagonist Xiao Heng eventually became the chief minister who was inferior to one person and surpassed ten thousand people. He was murderous and ruthless. What's even more sad is that it's still an inconspicuous supporting role. The original owner was timid and cowardly, and was fostered in the uncle's house. He was taken advantage of by the second prince, and his whole family was killed! Oh my god, the sky is falling! It's a bit confusing in the early stage, a bit sadistic in the middle, a bit sweet in the later stage, and the ending is a bit sad~
