Zhang Yuanqing was framed by Qin Linyu and Liu Ting. He was reborn and returned to the day when he was interrogated. He publicly testified that Qin Linyu had framed the former factory director Zhou Zhengyang. After that, he was repeatedly suppressed, but accidentally saved Xia Jinyu, the daughter of the chairman of the group, and gained the trust and support of her father and daughter. Zhang Yuanqing collected evidence of disciplinary violations by Qin Linyu and his men, and decisively dealt with the moths at the cadre meeting, but Qin Linyu counterattacked. He and Xia Jinyu conducted an in-depth investigation and discovered that Qin Linyu and his son used charity foundations and agricultural bases to hide embezzled group assets worth 80 million yuan. In the end, the Qin family and his son were brought to justice, and Zhang Yuanqing was appointed as the head of the group's disciplinary supervision department. He worked with Xia Jinyu to thoroughly investigate corruption and reshape the group's atmosphere.
