The harem would not be too large(I'm not sure how many but probably just 4-5 main and few other here and there). All the girls would be getting their time and story.2. The story is starting when the MC is in the middle of his growth stage and not at the very beginning. But his beginning will be mentioned in the story in some form.3. I don't think I need to mention this, but obviously it will not have any NTR, rape or that kind of stuff. It is actually quite a wholesome story focusing mainly on adventure, action and bit of romance and slice of life.

My newest Works are [Undying Warlord]& [Odyssey of the Blind God] are my newest works.

Nobody knew for sure because his fate was not set in stone!

However, what Kyle knew for sure, was that he had received a God-given opportunity to change something, to finally sense and start one of the major energies of the Universe.

Finally, he could start cultivating!

Follow the youngest reincarnation of the Old Souls, Kyle, on his journey through the pristine lands of the infinitely large planet, Shima, overcoming countless obstacles on his path towards unparalleled strength, with his Spirit Soul right next to him.
