Valerian, The Legendary - Chapter 139

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.

A human warrior cultivating the Ancient Strengthening Technique has transcended dimensions and arrived on Kyushu. Together with twelve ravishing beauties with looks that were unmatched in their generation, will he be able to stand on the summit of this world?

Qin Shiwu grew up listening to his parents’ love stories from an early age.

He learned that his mother was known as a beautiful, gentle and virtuous Omega at school.

He learned that his father was known as a talented and courteous scholar Alpha.

Rumor has it that when they were in high school, they fell in love at first sight, became a harmonious couple and never had a single quarrel.

Once he transmigrated, he went sixteen years back to the time when his parents were still in high school and became a little fool who was bullied by everyone.

Who will tell him——

This person who grabbed him by the neck and shoved him to the ground! The super as*hole school bully who can’t get 100 points in all nine subjects is his father?!

That cold, unfeeling, kaolin flower, iceberg person, the most alpha Alpha in the whole school whom no one dares approach within a 500-mile radius is his mother???

Wait, mom! Were you so wild when you were young? You’re pretending to be an alpha!

Wait, Dad!! That’s your wife!! Is it really okay for you to fight with him now!!
