My blue carnage system

The human race is at war is at war with the vicous variants and when they needed help more than ever, They started to come forward. Humans had hidden in the shadows for hundreds of years, people with abilities. Some chose to share their knowledge to the rest of the world in the hope of winning the war, while others keep their abilities for themselves. Luchan had lost everything to the war, his home his family and the only thing he had inherited was a crummy old wooden box that he couldn't even open. But when the box had finally opened, Luchan was granted a system and his whole life turned around. He completed quest after quest and become more powerful, until one day the system gave him a quest he wasn't sure he could complete. "It is time to kill!" "You must torture a human to death in 24 hours" "Your body will continue turning into a blue skeleton until the task is completed" But everyone thought that was the apocalypse and no one knew that the real apocalypse was about to start. After a few hours of the apocalypse the world government said that they were working on a tech called Hibernation pod a few years ago and it was now completed and we shall used it to make humans sleep for 2,568 years so after all this is over they can recreate the human population but no one knew that the world government was planning something malicious. Other work: starting off with the weakest ability in the apocalypse.
