From then on, Winters is divided in two: discreetly managing his affairs in the Western fantasy world, while diligently cultivating and comprehending the Dao in the cultivation world; advancing in both realms, he ultimately becomes the ruler of both! Years later, the gods of the original Western fantasy world cried out in unison, "Great Dragon Buddha, the revered God of the Sun and Order, King of Gods, Eternal and Immortal Dragon, Legendary Grand Magister!" The immortals of the cultivation world shouted in unison, "Welcome! Pleiades Hongyuan Mingdao Immortal Lord! Taiyao Boundless Creation World Venerable, Lord of the Thirty-Two Caves, return!" Winters merely smiled slightly: "This dragon is just better at hiding." ... Note: The author has been both a dragon and a cultivator, this is not just wishful thinking.
