My Disciple Has Truly Become the Emperor of the Immortal Kingdom

I planted a willow tree seed one hundred thousand years ago, and one hundred thousand years later, she became the Willow God. Half a million years ago, my mount began to practice. Half a million years later, my mount became a generation of demon kings, suppressing it for eternity. One million years ago, I saved a female doll. Two hundred thousand years later, she became the empress. Five million years ago, I took on a disciple. Five million years later, he became the emperor of the Immortal Kingdom.
