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?

Alex Jin was just another overworked nobody until a truck crash sent him into the body of Valerian Nightshade—the cold-blooded villain from a popular fantasy novel. Destined to die early as the stepping stone for the “hero,” Valerian was powerful, rich, and feared… but ultimately doomed.That is, until the Villain Evolution System activated.Now, every villainous act rewards Alex with unimaginable power. Crush a rival? +100 Strength. Manipulate a noble house? Unlock a rare bloodline. Kiss the heroine meant for the hero? Well... let’s just say the rewards aren’t all measured in stats.To survive, Alex must outwit plot armor, bend fate, and ascend to the throne of power in a world that expects him to lose. But the deeper he goes, the more he realizes—being the villain might be the only way to save this twisted world.This time, the villain won’t die early. He’ll rewrite the story, one ruthless step at a time.

The Apocalypse descended as the world turned into a game. And while everyone panicked, I couldn’t help but wonder if there was something wrong with my eyes.[Logging into the Game Master’s Account!]And my ‘oh-so-average’ destiny, changed into ‘is this a cheat life?’ Kind of destiny.[Would you like to Create a Skill? GM Points will be consumed!]While others struggled to kill a single goblin, I was searching for stronger monsters. While they were happy with getting even a random weak skill, I was customizing what kind of skills I needed.Even my Talents and Gifts can be customised. The only limit was my imagination.Heck, even the hidden quests that people would trigger randomly were present in front of me even before the scenario began.It wasn’t fair by any means. But isn’t that how life is already?[Would you like to make changes to the quests in the next scenario? GM Points will be consumed!]Is this how an apocalypse is supposed to be? I don’t know. I just tried following the script in front of everyone while trying out my cheat in hindsight. Don't get me wrong with the ‘pig eating tiger’ kind of thing. I just don’t like attention. I would rather stay with two trusted friends than with 10 fake ones.[Would you like to Initiate a Custom quest for the Players? GM Points will be consumed!]And for the players who were bullying the ‘weak’ me. One may even wonder how they ended up losing half of their stats and skills in a randomly triggered impossible type of quest.Fate can be truly scary, you know?One must always be careful of it.

However, through a chance encounter, he gains access to his familiar laboratory that will allow him to study the wonders of cultivation.Not even the heavens will know what fate has in store for Langley as he systematically unravels not only how to cultivate, but also various crafts such as refining pills and inscribing talismans. Preparation is key to surviving in the merciless world of cultivation, especially for those with no talent.Expectations:- Detailed study of each stage of cultivation and crafting- Not technology vs cultivation, scientific method will be used to study cultivation- No harem- Slow burn progression.
