Unsealed Rising to the Top with My Son

"For tens of thousands of years, the Cultivation Realm has been without a Heavenly Emperor. The protagonist, Vance Sharples, was once severely wounded in a secret realm where he awakened the Heavenly Emperor Cultivation System. To protect his wife, he endured a decade of suppression, masking his cultivation base and posing as a useless Golden Core cultivator. Yet, he was betrayed by his wife, Moira, and humiliated by the Lewis family, who forced him away. Driven into a corner, Vance breaks his seal. Together with his son, Kyle, he slashes through all obstacles, unlocking the Myriad Tribulations Immortal Physique while using the system to deduce ultimate techniques and defuse every crisis. Shocking everyone at the Azure Trial, he slaps down his snobbish enemies. Ultimately, triggering the Primordial Dragon's Roar, he breaks through to the Heavenly Emperor Realm. Leading his son to the ultimate peak, he takes control of the myriad realms and achieves an eternal legend."
