MTL - The Legendary Mechanic (Transcendental Mechanic) - ~ 390 Aroxia, A-level serial mission (on)

As disaster was about to strike, a group of survivors transmigrated into a desolated world and were challenged to a game of survival. From terrifying acid rains, to endless natural disasters, the heavens burn while the earth scorches, radiation is rampant, and nobody is spared from the dangers of this hellscape. The only way one survives is by building a shelter and slowly upgrading it in hopes of surviving another day.

Nobody thought the end of the world as they knew it would come like this.In a dystopian future, 95% of the population was sent to another universe, one resembling the game Jack had played, “Elder Heir Online”.He would've normally enjoyed such an opportunity, but the company 'DiveCore', from his real world, came along.As long as any of them breathed, his revenge wouldn't be complete.Using his knowledge of the game, and willingness to go through the worst to exact vengeance, he will slowly become what he avoided when he played the game in the real world: a villain.

In the middle of a deserted island, a small boy wakes up with two sets of memories: one from his few years of life and the other from a man who lived to adulthood and achieved great things. When he least expected it, a powerful master appeared on the island and took him in as a disciple, revealing a shocking fact: magic exists in that world, and, thanks to it, humanity managed to conquer the galaxy.
