This Great Emperor is Overly Powerful

He once swept across three hundred and sixty-five countries, establishing the Nine Heavens Divine Dynasty! He once suppressed the Dark Turmoil, making the behind-the-scenes manipulators tremble. He once traversed the ancient and modern, debating the Dao with the supreme beings of the past in the river of time. He once saved the world, resisting the invasion of the Chaos Clan... He is the supreme Great Emperor, the representative of eternity, the symbol of invincibility. But now, he is about to fall. After living for eighteen thousand years, due to fighting in all directions, leaving behind a body full of hidden injuries, old age is ominous, the Emperor falls to the Nine Heavens.
