The protagonist, Winnie (文尼), confesses his love to his childhood friend—the princess he’s been secretly in love with for years—but is brutally rejected in public. His heart shatters, he’s humiliated and ridiculed, and he collapses unconscious. When he wakes up, he vaguely remembers his past life’s memories and realizes he has transmigrated into the world of an otome game he played before. At first, he’s thrilled, thinking, “Nice! I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?” But then… surprise! He’s not just the villain—he’s the “Saintess”!

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.

Lu Chang’an cultivated the reincarnation of immortals for two generations, and in the third life, An Wengou reached the Nascent Soul stage, solved the mystery of the reincarnation stele, and then practiced the mediocre ancient health-preserving skills.

Avoid fighting and fighting, operate steadily, and form good relationships with people.

After a long cultivation career, I got acquainted with growing characters, upright leaders, celestial beauties, demon giants, evil cultivators, thousand-year-old monsters, behind-the-scenes chess players…

Watch the ups and downs of the world, the ebb and flow of the tide.

Unknowingly, it has become a living fossil in the world of cultivating immortals, an evergreen tree through the ages.

…………

Mortal flow, stable, pseudo-longevity, decisive killing, and normal three views.
