His Majesty's Devious Sins - Chapter 37 - I Dont Taste Very Good.

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.

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.
