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?

Strange not only becomes the Sorcerer Supreme after being reborn and possessing that body, but he also forms unexpected bonds with the Avengers, takes part in epic battles, and manipulates time and reality to prevent critical alterations in the timeline. However, despite his power and wisdom, his life is constantly interrupted by duty, leaving him no time to enjoy the youth he longs for.Just when he thinks he has gained complete control, in his sacrifice for the world, he is reincarnated again—this time in the Harry Potter universe, where he is reborn as Stephen Flamel, the adoptive grandson of the legendary Nicolas and Perenelle Flamel. Now, with a second chance to enjoy his childhood, Stephen embarks on a new adventure in a world full of magic.Notice: It contains yuri from a secondary character who shares prominence with the main character in later chapters.And no, it is not NTR.

Humanity's end came without warning when a crimson fog swallowed the sky. Zhao, an ordinary man, watched in horror as a celestial voice declared their fate: their Planet had reached its limit, and its people would now atone for their sins. An otherworldly force crushed resistance, and in an instant, every human was teleported to the Central Land, a vast and hostile realm.The voice from the heavens promised trials that would shatter their wills, but also power beyond imagination for the fortunate. Only those blessed by luck would awaken unique Lord Talents, granting them the means to survive and dominate:In a world where strength lies supreme Zhao will do whatever it takes to get stronger.Zhao awoke in an isolated area near a forest. As despair set in, a voice echoed in his mind:Ding… Million Times Multiplier System has been activated.Just as the rest of the players had known of the world Zhou's subjects were clearing out every resource.When others were building their base he had built a kingdom.And by the time they knew of his threat, HE HAD ALRDY BECOME GOD!
