The Dungeon Seeker - Volume 5 Chapter 1 part3

Luo Wencheng made a deal with a certain existence and went back in time to ten years ago, when he had just been released from prison, still young and healthy, not yet pushed to the breaking point by Luo Wenjun and not yet used by him as a prop to test drugs for profit until his tragic death.

This time he was going to trample Luo Wenjun underfoot.

The first priority was to steal Luo Wenjun’s future backer from him.

My childhood friend went to the academy.

Lyu Liang was an ordinary young man who was supposed to live a mortal life with his father in a small village. However, a wonderful opportunity led him into the Virtual Land where he learned about his unusual origin and started his dual cultivation journey—to be a Devilish Immortal. There were six races in this world: immortals, humans, devils, demons, ghosts, and spirits. Lyu Liang had access to any of those realms. Whether he would be a great Devilish Immortal was not up to his race, but his will. For him, it was not important to be the most powerful immortal and to be worshiped like God. He eventually chose to live a secluded life with his lover.

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.
