Lin Chang Nayun suddenly transmigrated into a cultivation world one day. The only things he had were his desire to live and maintain his authority. He devoured hundreds of billions of celestials from the lowest realm of cultivation world all the way up to the end of "Onalon", the border of existence! “My lord, why are you trying to go back? You already have everything that you could possibly desire here in Navryth.” “I have everything? But everything here is created by me and nothing is natural here. I haven't destroyed the reality till now because I want to experience everything that I didn't create!” This place, Navryth, the celestial doom island at the end of Onalon is just a landscape with some celestials, like billions of them and a small castle, that's all! ***** “I've decided! I’m going back.” He finally goes back to Earth after 90,000  grueling Nevalon years!
