I'll Die of Embarrassment to Save the World

Fired from his job, betrayed by his girlfriend, and chased by loan sharks until he jumps into a river, Yang Wu thinks his life has hit rock bottom—until a Nokia phone falls from the sky and hits him squarely on the head. "Ding! Detected host's luck value as negative, meeting the criteria for 'Heaven's Chosen Unlucky One.' [Luck Loan] System binding!" "Now providing newcomer benefits: borrow a bit of 'good luck,' at the cost of singing 'Song of the Good Men' in the city center square tomorrow." At first, Yang Wu's heart is full of refusal. But when he uses the borrowed luck to win a 'free extra box' with instant noodles, dodge a fatal car crash by tripping, and coincidentally get all his enemies thrown in jail... he gets it! What is repaying debt? It's 'recycling investment in social merit'! What is dying of embarrassment? It's 'collecting emotional energy for spiritual civilization'! From then on, a philosopher of shamelessness and a master of twisted logic emerges! Stealing his senior brother's elixir? It's to bear the poison risk for him. Hiding behind the school beauty in battle? It's to unlock her combat potential. Getting the whole school into trouble? It's to temper everyone's willpower! He, Yang Wu, always walks on the front line of taking advantage, yet always stands at the moral high ground! — Description from novelcodex.org
