My Wife's Master and I: The Ultimate Counterattack

Ye Ran transmigrates into a cultivation world and accidentally awakens the strongest system, but is trapped by its rules at the mountain gate, hiding his peak power and becoming a mocked 'useless disciple' at Lingxiao Sect. After enduring humiliation for years, his former fiancée publicly breaks off the engagement. Just then, her cold and transcendent master, Master Nan Gong Meng, comes to comfort him, accidentally triggering a system mission to leave the mountain. From that moment on, Ye Ran breaks his constraints, unlocks his cultivation, and while sweeping aside the sect's provocations, investigating the blood feud of his destroyed family, and uncovering the secrets of the demonic sect, he also protects Master Nan Gong Meng as they fight side by side against enemies and overcome crises together. Starting as a restrained disciple, he counterattacks to reveal the sect's conspiracy and eventually becomes an unparalleled powerhouse dominating the three realms.
