A hundred thousand years ago, the Immortal Emperor of Heaven and Earth occupied far too much territory across the universe's star domains, provoking the resentment of several other Immortal Emperors, who joined forces to attack and kill him.
In the midst of the great battle, a single strand of the Immortal Emperor of Heaven and Earth's hair was swept away by the fierce winds of battle, traveling countless miles. A remnant wisp of his soul clung to the strand of hair and drifted through the universe for countless millennia.
At last, it fell upon the barren Blue Star. After tens of thousands of cycles of reincarnation, it finally reincarnated as a human. The soul grew from an insignificant nobody into an adult.
After the nobody cultivated the complete Immortal Art of Heaven and Earth, his power rose rapidly. During this time, he did many good deeds for his country and its people, and helped his nation grow powerful at an astonishing pace.
When his nation stood at the top of the Blue Star, a cauldron and a cultivation formula came together. He then devoted himself to cultivation once more, becoming even more powerful than in his previous life. He later returned to the immortal realm and avenged himself for his past life's grudge. From then on, the entire immortal realm fell under his rule, and he became the only great Immortal Emperor to coexist with the universe.
