MTL - Rebirth Turn of the Century - Chapter 663 no one knows

A man who was once called the world’s strongest agent ended up becoming a teacher after his retirement, to train a new generation of agents. After many years of training his disciples, he was killed at the age of 60 by a secret organization’s ruse and was reincarnated in another world with his memories intact. Though he was surprised by the existence of magic and the strange species in that world, he quickly adapted to his condition as a newborn and took advantage of it. He acquired special magic and gained a massive amount of strength thanks to his rigorous discipline, in order to reach his goal: Resume his career as a teacher which he left halfway through in his previous life. This is the story of a man, who, based on the memories and the experiences of his previous life, became a teacher who travels through the world with his students.

Xiang Ye, who was working overtime and died suddenly, woke up and found that he had turned into an acre of land.

Just when he was at a loss, several big men carried a female corpse and buried it under him.

The accidental corpse dumping case made him uneasy, but then something even more shocking happened. The female corpse buried deep in the ground came to life on a certain moon hiding in the clouds at night…

“I don’t want to be a paradise, I want to be the most ferocious and most evil in this world.”

PS: It is probably the story of an acre of wasteland becoming a fine.
