Five years ago, Song Yu was a researcher with a great future in the monster research center.
His research project was on how to extract the vitality essence from monster cells and inject them into the human body to induce the genes that had been slumbering in the human body for billions of years to change and obtain the power of monsters.
When Earthlings transmigrated to the Other World, they discovered that monsters were carbon-based life forms that went against all logic.
Research regarding how to use monsters effectively and scientifically had never stopped.
Killing monsters and eating their flesh, drinking their blood, as well as absorbing the spirit energy contained in monster crystal cores to refine the human body until it became steel was one path.
Domesticating and modifying monsters by implanting control chips into monster brains and turning wild beasts into obedient biochemical pets was another path.
