I Helped You Become Immortals, and You Didn't Appreciate It. So Should I Just Leave?

Cultivation, settling scores, decisive killing, invincibility, no System, I am the Heavenly Dao 'Like flowers and trees, let your heart grow toward the sun. Take good care of the sect, your senior sisters, and your junior sister, who will one day be your wife.' Those were the last words Xiang Yang's mother spoke to him. So for eighteen years, Xiang Yang quietly gave everything he had and looked after the sect. But his senior sisters treated him with contempt, his master and mistress only wanted to seize the cultivation resources that should have been his, and his junior sister would have gladly killed him just so she could be with his junior martial brother. How could he keep listening to his mother's advice? After waking from a dream of empty glory, Xiang Yang realized that if he kept being kind, he would only be ruthlessly exploited and die with bitterness in his heart. So he let go of his attachments and reclaimed the fortune of the Heavenly Dao, taking every opportunity firmly back into his own hands. From then on, he comprehended the Great Dao, formed contracts with divine pets, became the Lord of the Great Dao, and led humanity to dominate the Myriad Worlds. The Great Dao is contested. Anyone who stands in my way dies! Only then did his master and senior sisters realize their mistake. His junior sister wept and begged for forgiveness, while the junior martial brother he had fleeced bald knelt and pleaded for mercy. But it was too late. The surrender button is in the upper-right corner. Too bad you won't live long enough to choose it!
