Conquest of the Evolutionizing Extraterrestrial Being

‘I want to live…’ [... I can let you live but on one condition] ‘... I will do anything if I can live’ [Then become a monster among monsters, you shall kill, command, capture, rape, consume, and evolve to become the strongest monster in my world. Show me your resolution, give me some entertainment]  From that very day, Wei Yang died in a hospital bed after contracting an incurable disease. Gifting him a chance at rebirth right before his death by an unknown existence, he accepted the conditions stated and took its hand. When he awoken as a monster, the conditions he had made before grew on him and made him grow stronger and stronger. Will he be able to survive until he reaches the pinnacle or will he fall along the way. Warning: Has slight elements of Futanari. It also contains quite a bit of bloody gore and some other dark elements. Read at your own risk. ( slight meaning it plays only a small part of the story, mainly for lols)
