My Soul card is a Reaper - Chapter 2 A Scythe And A Hourglass

She is intelligent, beautiful, calm, and professional. As the youngest chief forensic investigator for the past few years, her future was very bright. All of this, however, changed with a bizarre time-travel.

An angel made a mistake, resulting in Shiihara Daiki’s death. In order to hide the mistake, he was then sent to a different world. The angel will grant him one wish as a payment for keeping it a secret. Daiki asked for a Heavenly Castle floating in the sky without hesitation.

Suddenly a floating castle appeared in the new world, which causes confusion amongst the people. They attempt to contact Daiki in various ways. A country tries to steal it by force, while another seeks to befriend him. What in the world would Daiki do?

A series of nine stars occurred here, and various creatures violently mutated, killing the former overlords – humans crazily.

Thermal weapons are no longer humanity’s trump card.

Fortunately, mutations have also occurred in humans.

Human beings will awaken their bloodline at a specific time and gain the inherited power of various ferocious beasts.

And Xu Mo, who obtained the system, was even more outrageous.

He awakened the bloodline of the ten ancient beasts and led mankind to regain its dominance! !
