I Swear I Don't Have A Python In My Pool - Chapter 26

Since the opening of the Dungeon Rifts-- also called D.Rifts or Drift Dimensions, the world has changed. It's become more militaristic and violent-- unpredictable, even. Monsters raze cities and bring diseases that birth new races. Magic exists in a constant state of hyperflux, birthing new powers and changing the functions of old ones.But none of that mattered for Rex. He wasn't a Drift Soldier-- as much as he wanted to be. He didn't have powers-- even if he wished he did, so when he graduated primary school, he expected to get his Drift Armament and find a bit of consistency for once in his life.But you know what they say about expectations......DING![Congratulations! You have awakened the Beast-Totem and unlocked your Werepanther System.][5 Totems Remaining....]*********Extra tags: kingdom building, military, martial arts, overpowered, scifi-fantasy, post-apocalyptic, factions,

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?

The fiancée has betrayed, but how could she know that the man she looked down upon was in fact a prodigy with healing and martial prowess!

Eli was transmigrated to a world of magic and became immortal.

He had endless life and could never die.

“Huh? I’m talentless? Then, I’ll just train for as long as I need, even if it takes 1000 years. That should be enough for me to become strong.”

“The skill is hard to learn? Then, I’ll take a few dozens of years to research it. There’s no way it’s that hard, right?”

“What? I can sacrifice my life force to gain spirit power? That’s a bargain!”

“The enemy is here? Hell, I’ll just hide for 10000 years. Let’s see if he can outlive me. I’ll come out once he’s dead.”

This is the story of an immortal who first struggled to live in the world of magic until he became strong enough to slaughter endless worlds.
