The Overpowered Hero in a Broken Engagement Plot, but I'm the Fiancé

Xie Cizhi once heard the System say that his marriage partner from a small clan was a destined protagonist, someone who would suffer a major setback in the future, turn dark, make a comeback, face-slap all the cannon fodder in his way, and ultimately reach the pinnacle of the continent. He sounded pretty promising. Xie Cizhi nodded, perfectly willing to wait for the destined protagonist to buckle down and work hard so they could meet at the top. Lu Mingjian had extraordinary talent, and his cultivation had always gone smoothly. Then one day, disaster struck. Lu Mingjian began coughing up blood nonstop, and his meridians were almost completely shattered. [Ding-dong!] System: A major setback for the protagonist has arrived! The protagonist’s power has plummeted, leaving him a cripple, while his vicious fiancé takes the opportunity to kick him while he’s down, breaking off their engagement with a letter of repudiation. His heart deeply wounded, the protagonist begins his dark transformation and comeback! Xie Cizhi: … So he’s the cannon fodder side character! Wait, with his strength and looks, how could he possibly be cannon fodder?! * After the engagement was broken off, Xie Cizhi’s new marriage plans kept being delayed, with no match settled for ages. The candidates were fiercely competitive, so the Xie family head simply decided to hold a martial arts tournament to choose a groom. Just as registration was about to begin, Lu Mingjian rose from his long-silent state as a cripple and reclaimed his position as the Lu family’s young master, once again enjoying unrivaled glory! Thirty years east of the river, thirty years west: Lu Mingjian stormed Xie Yunguan with his sword, his sights set squarely on Xie Cizhi! The once open-faced young man now wore a gloomy expression. He calmly wiped the blood from his sword. His spiritual energy filled the hall, pressing down on everyone until they could barely breathe. They were secretly astonished: he was even stronger than before. Xie Cizhi: Here to fight? Lu Mingjian: … Lu Mingjian: Here to sign up. *Xie Cizhi x Lu Mingjian *An outwardly innocent and harmless but truly dangerous gong x a carefree, uninhibited shou who is obsessive beneath the surface *The pacing is unhurried, with plenty of everyday scenes, a touch of everyone-loves-him, some melodramatic misunderstandings, and a bit of brothers turning against each other for love Theme: Thirty years east of the river, thirty years west of the river. Never look down on a young man just because he’s poor.
