Immortals Journey: World's Evolution

Lee was born with an immortal body, no matter what happened his body would always reform, even if he were completely reduced to dust. living through centuries trying everything the world had to offer, he picked up many skills and honed them to perfection. however boredom started to set in as there wasn't much he hadn't done, his world was rather plain after all. There was one thing he never did throughout his life and that was have a family, he never wanted to see them die of old age as he has to live on. Then one day everything transformed, two worlds merged together and created a new one, filled with divine beasts and powerful mages, dungeons formed across the land with evil monsters and bountiful rewards. mystical races thought to be fantasy became common sight and new landscapes were waiting to be explored as the world expanded many times over. with new things to discover and a magnificent journey ahead, Lee sets out to explore the new world. maybe even make some friends along the way and try the whole family thing who knows, with this new world maybe he won't have to worry about watching them slowly age away. MC may be centuries old but with the new world he becomes rather excited and energetic again, also he was never really the smartest man so don't expect immense wisdom, although he will know alot of things since he tried out alot of things in his world before the merge. however he won't know anything about magic until he learns about it and how to use it, to make things easier to understand and visualize ones power a system will be added to show stats this novel probably won't be started for a while cuz it's just an idea I randomly had and I'm not exactly keen on writing all the time so if I do start it chapters will be pretty random unless I start enjoying the writing, r18 tag is because if I do write this there will probably be some pretty gruesome descriptions of kills occasionally and maybe just MAYBE some ecchi content once he finds a love interest for all those men of culture out there.
