MTL - I’m a Straight Man in BL Love - Chapter 36 guess the gift

In a world where martial artists reign supreme, strength is everything. Unfortunately, that logic doesn't apply to a certain Florida Man.

Refined in the nuclear fallout wasteland, Leo was the strongest mutant alive. He carried an alien artifact, allowing him to exchange his lifespan for modern items. After 50,000 years of solitary life in a humanless world, he collected enough lifespan to transmigrate to another habitable world.

Leo was later thrown into a mysterious planet. He soon discovered that his body produced radiation, and it mutated the surrounding plants and grasses. Worrying that he might ruin the beautiful planet, he chose to live in seclusion.

Unfortunately, the local population soon discovered his existence, and a misunderstanding ensued.

Ancient existences wake up in the abyss, demons whisper in people’s ears, unknown horrors erode the spirit, and madness breeds in the darkness of people’s hearts.

But it is not only darkness that descends on this world.

There are heavily armed dark knights walking in the dark to judge crimes; tight-fitting supernatural beings wandering between buildings to act as friendly neighbors; The impossible god on earth, the “S” symbolizing hope shines like the sun on his chest…

No one could have imagined that behind all of them, there was just a player sitting in front of a computer screen holding a keyboard and punching hard.
