A Step into the Past - Volume 25 Chapter 4

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.

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?

Born into a lower middle class family, Ace Lander grew up being told there was a simple formula for success: get an education, graduate, and work hard to build a prosperous future. But that formula failed him during the final stretch of his senior year when a local gang targeted him, putting everything he had and was building towards at risk.Trapped and desperate, Ace felt his life spiraling out of control—until Ria Hart, a fellow classmate, discovering Ace's innate aptitude to become a Curse Master, a being capable of wielding curse energy and abilities but haunted by Curselings, took pity and introduced him to the secret world hidden beneath the mundane surface of their world, the World of Curses.Awakening as a Curse Master, Ace discovers he possesses an extraordinary innate curse tool: the Cursed Toybox. This tool comes with a unique class, Toymancer, granting Ace powers unlike any curse master the world has seen before.

Gu Shishi, a master of traditional Chinese painting, transmigrated into the role of a cannon fodder in a cliché novel.

The cannon fodder female supporting character was switched at birth. She had barely spent a few days with her biological parents before she was tossed into the wolf’s den by those same parents. Her parents, having no heart to send their fake daughter with a heart disease to live a hard life, forced the real daughter into becoming the replacement. Gu Shishi was sent away to marry the big villain – the rumored evil, cruel, and wife-cursing first young master of the Huo’s.

On the very first day that she had transmigrated, she had to face her fated tragic death….

Luckily, she had also inadvertently discovered the path to altering her fate!

— The more gifts she received from the big villain, the longer she could live and the more cheats she would gain!
