Restarting From Genesis - Chapter 25: The Fighter Soul.

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?

Gu Ting Yu is a veterinarian with a fear of animals. Haunted by the same nightmare all these years, he is desperate to find out the reason behind those dreams. He then travels into a fantasy realm by fate, entering the Palace of the Twelve Sacred Beasts.

Rick Rolland didn’t expect to die young while gooning to some peak milf video, and he definitely didn’t expect to wake up in a world of dragons, elves, ancient empires, and magic older than civilization itself.But even worse than death was the cheat ability he received. Right after reincarnating, a small glowing figure floated out of his chest.A tiny chibi old-butler spirit with monocle, mustache, and a permanent irritated look.“Ahem. Welcome to Zorathia, gooner user.”[MATURE AFFINITY SYSTEM ONLINE]“You can only gain EXP by increasing affection with women aged 30 or above. Try not to die… while gooning again because you can have womans now...”Rick froze. Other isekai heroes would kill goblins, slay dragons, or train with legendary swords.But him? He levels up by seducing older women.“Slay goblins? Too simple.Lift a sword? Too mainstream.You, gooner user, must charm experienced ladies until they blush.It builds character and yours is nonexistent.”And just like that, Rick’s life in Zorathia spiraled into chaos.--------------------------------------------------Disclaimer: No NTR and Yuri.
