Perfect World: Double Pupils Open the Heavens, Ascend to Immortality

Having traversed a perfect world and bearing the name of the Double Pupils, Shi Yi embarks on a path to heaven.
"With double pupils, heaven and earth are opened; since ancient times, there has been no defeat in the human world!"
The two stones clashed, their battles never ending, from the eight realms of the lower world to the three thousand provinces, from the budding immortal flowers to the fallen emperors, from bloodshed to immortal kings and immortal emperors, from spurring each other on to reconciliation, from enemies to brothers.
"Even you will grow old one day?" As the years passed, Shi Hao looked at his cousin, whom he had pursued all his life, now with white hair and said in disbelief.
……
Tianyuan, Shi Hao was too weak to fight any longer, and could only watch helplessly as Yu Tuo's hand reached for Zuizhou, his eyes wide with fury.
"Save her!"
"Do you need to tell me?"
……
He destroyed Anlan, suppressed Wushang, and severed Yu Tuo's hand. In the Nine Heavens, he slew the immortals, destroyed the long-lived, and purged all evil. In the Three Thousand Dao Provinces, he suppressed the Six Immortals, swept across the universe, restored the innocence of the sinful race, and restored a clear and bright world to heaven and earth...
"Brother, you don't owe me anything."
……
This is a story about a man with invincible double pupils who ascends to immortality, a clash between the "Ascension Technique" and the "Secret Realm Technique," and brothers who are both enemies and friends, but will eventually find peace.
PS: The female lead is a witch, a woman with double pupils, named Lin Ni (a member of the Butcher Clan, a blonde woman in the bud of the Sun God Tree).
