I Failed the College Entrance Exam and Started Collecting Scrap, Then My Toys Became a Shadow Army

During the college entrance exam's math test, a line of text suddenly appears before Jiang Luo. Choose one: A. Gain the ability to turn trash into treasure. B. Score 700 on the college entrance exam. He thinks the pressure has made him hallucinate and silently chooses A. As if it could really give him a score of 700! The words fade away. He pays them no mind and continues answering the questions. But on the day the results come out, the total score of 250 on the screen makes his eyes sting. How is this possible? He's a top student. Even if he messed up, there's no way he'd score below 600! His parents stare at his results in silence. A relative calls. “My kid scored over 530! What's the use of your Jiang Luo usually studying so well? What matters is doing well on this one crucial exam!” His unrequited love texts him: “Jiang Luo, I know you didn't do well on the exam... We can still be good friends. Will you keep being my knight and protecting me?” Only when he boards the bus to repeat his final year does the line of text appear again: “Congratulations, Host. You have successfully activated the ability to turn trash into treasure. From now on, any scrap in your hands could become something beyond your imagination.” Jiang Luo is thrilled. So it wasn't a hallucination during the math exam! In a scrapyard, his fingers have barely touched a plastic child's mask when a prompt appears: “Congratulations on turning trash into treasure. You have obtained a Shadow Clan mask!” Shadows surge in from every direction, filling the whole alley, packed onto rooftops, into cracks in the walls, and beneath manhole covers. They all kneel in unison! The Twelve Talismans, Devil Fruits, the Three Types of Haki, hundred-thousand-year Soul Rings, Heavenly Flames, the Dao Fruits of Great Emperors... Not long afterward, Jiang Luo says, “So what if I failed the college entrance exam? I've become someone you could never imagine.”
