Ye Ting binds the Qingfeng system. To rectify social bad customs, he chooses to sneak into the chaotic cycling circle to go undercover. He purchases a second-hand bike at a low price, joins the high-end cycling group through Jiang Qing, and participates in dual cycling activities under the alias Chen Zhou. Facing the sneers and ostracism of insiders like Wang Haoguo, Ye Ting resolves crises with wisdom and system assistance, gradually exposes dark secrets such as equipment forgery and emotional fraud, and finally dismantles the illegal gang, achieving circle purification.
