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.

Twelve years ago, an old beggar found an abandoned baby and took him as his own son, naming him Xu Han. But when his foster father dies, Xu Han finds himself in a training camp with dozens of other kids, though what they’re training for remains a mystery. It’s here that he meets his best friend, Liu Sheng, and life is good for a while — regular hot meals and a safe place to stay. But kids keep being taken and not coming back, and eventually, Xu Han and Liu Sheng find themselves left in the woods at night, where they discover what’s happened to the kids who disappeared before them — they’ve been turned into zombies! Can the pair destroy the zombies and survive the night, or will they be the newest victims of this twisted conspiracy?

In the year 3000, humanity was forced to leave the earth when a sudden mutation caused more than 70% of the planet's population to mutate either into zombies, werewolves or vampires. The humans put up a fight but didn't have a chance against the united front of the monsters and they were forced to leave. At least those who were rich and lucky enough to leave.

A century later, the chaos on earth had calmed down but the humans who were left behind were treated like slaves and were forced to join one of the three factions: The Undead, The Cold Ones or The Lycans when they turned 16.

It was a similar story for Ashton, who was one week away from being turned into one of the monsters as it was his 16th birthday. He decided to run away from his fate and join the secret resistance to battle against the monsters.

However, his plans came to a standstill, when a series of misfortunes leads him to be bitten by a Zombie, a Vampire and a werewolf before either of his powers could manifest.

He ended up receiving all of their powers, but at the cost of his humanity. Yet, he wasn't willing to let his humanity die. No matter the cost.

Will he be able to live his life, or was it already too late? Which faction will he join? Will he be able to find the secret behind the mutation?

There were too many questions, and only one way to find the answers: follow Ashton's journey as he fights back to retain his humanity.
