Lin Xiao is a notoriously stubborn computer market worker who insists on not using refurbished mining cards and off-brand power supplies, but was driven into a leaky basement for offending peers. On the day of the esports tournament, three hundred computers collectively blew up, data disks burned to charcoal, and three million in liquidated damages forced everyone to beg him to come out of retirement. With a single microscopic jumper wire, Lin Xiao saved the competition and exposed the counterfeit scam of unscrupulous merchants. Those who once mocked him lowered their heads one by one, while he established only one rule: repairing computers is fine, but going against one's conscience is not; computers must not burn the heart, and people must not feel chilled even more.
