The Male Supporting Character Only Wants to Take the Imperial Exams

Chen Bujian transmigrated into a book with a card-drawing System, becoming a disposable male supporting character in the male-oriented novel The Richest Merchant in Another World. The disposable supporting character and the male lead were switched at birth. While the male lead enjoyed wealth and luxury, the supporting character lived a life worse than death. At long last, he returned to his biological parents, only to discover that his father doted exclusively on the male lead, while his mother treated him like the apple of her eye. The only person who truly cared for and cherished him was his grandmother. But she was old and unwell, and she passed away less than two years later. The supporting character was naive and impulsive, with no idea how terrifying a grand household could be. In the end, he could only become a stepping stone for the male lead. Fortunately, Chen Bujian had a card-drawing System. First, he had to help his grandmother live a long life, then cling tightly to her for support. Next, he would choose the opposite path from the male lead and pursue the imperial examinations. No matter how rich the male lead became through business, he would have to kneel and address Chen Bujian as 'Your Excellency.' Content warnings: 1. The male lead has an extremely powerful golden finger. 2. The setup takes quite a while. The imperial examinations don't begin until more than twenty chapters in. 3. One-on-one romance. Theme: Fear no adversity; meet challenges head-on
