- Description from Novelupdates

A world filled with heroes with superpowers. A world attacked by calamity fiends. A modern world filled with wonders and dangers.

After a long slumber, Zhou Yi wakes up in a wasteland era. He discovers that the new humans, to avoid the daylight supremacy of the Guangna species, only dare to come out at night, meekly whispering in the darkness and scavenging for trash. Exasperated, he questions how humans could have deteriorated to such a state. Lamenting that each generation seems to be worse than the last, Zhou Yi decides to show them the ways of the older generation. Embarking on a quest to transform the wasteland, he aims to rebuild the lost splendor of humanity.

A world from another dimension suddenly appeared in the Milky Way galaxy and collided with the earth. A spatial collapse occurred, which allowed the monsters crossing over from the other side to invade various countries, and the earth fell into great calamity.

The military was powerless against the invasion because modern weapons didn't work against monsters from another world. Under the desperate situation, a god-like figure appeared and bestowed blessings upon the humans to awaken their power. From then on, the earth regained its hope, and these extraordinary people were called Realizers.

Tenku Okuihara is a five-year-old boy who dreams of becoming a Realizer to protect the world and his family. But an incident changed his life goal from a hero to a grim reaper.
