Eternal Across the Ages in the Cultivation World

After transmigrating to the world of immortal cultivation, Han Chen realized he possessed the Dao Fruit of Longevity and had mastered the mysterious power of eternal life. A useless Five-Element Spirit Root? That was merely how ordinary people saw the most worthless Spirit Root of all! Han Chen paid it no mind. He knew that as long as he persevered, if a thousand years was not enough, he would try for three thousand. And if that still wasn't enough, he would try for ten thousand! One day, he would make this so-called useless Spirit Root shine with a brilliance unmatched in all the world. Even a Deity Transformation cultivator would have to bow before him. Billions of years later, even an Immortal Emperor would have to concede defeat beneath his radiance and stand aside.
