MTL - I Built An Empire And You’re Telling Me That I Wasn’t Transmigrated? - ~ Chapter 13: The Mysterious Underground World

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.

Liu Ming, since he was young, lived in a savage prison named Savage Island where the prisoners aren’t controlled by any guard or security. When the island sinks due to “mysterious” events, only a handful of people survive – those survivors are then pursued by the government.

On the other hand at another place two practitioners are worrying about what will happen to them because the young master that they were supposed to protect had died.

Their young master looks nearly like our MC
What will happen?

In a mass ambush at the Battle of the Gods, the four major guilds with all their armies surrounded one man alone: McRae, known by all players as the God of War.

But even the God of War could not survive alone against hundreds of attackers.

Yet, when McRae opened his eyes again, he’d returned to the first-day launch of the game, [Divine Domain]- and he still had his full-level character, with all classes available to him to switch freely between at any time.

With all his previous memories, McRae knew that their entire world would soon merge with the game world, where death would become permanent… And so he turned on Divine Domain once more– this time fully aware of every detail about the players, the treasures, and the game itself.

Before the four guilds were even formed, McRae would have a guild and an army of his own.

This is a story of a little man who walks forward silently, in awe, and strives to chase his dream.
