Xu Cheng Yi leaves the company, and Ling Wei becomes the Chief Technical Officer. Xue Ning returns and takes over the Operational Department again. Without Xu Cheng Yi, Xue Ning goes further in the persecution of Xia Yan, depriving her of all her projects and making her the errands girl in the operations department. Xu Cheng Yi, though he is on leave, does not stay idle but prepares to further optimize Setup's algorithm. Xue Ning's return makes the atmosphere in the Operational Department unusually depressing, and the salary performance is cut by two-thirds of what it was before. Some employees submit their resignations. Zhao Xiao Jun is unconscious due to injury, and Lin Hao is detained by the police. After having learned from Yan Chang Jun that the gifts Ling Wei received were all bought by herself, Xia Yan's suspicion of Ling Wei gradually increases. (Source: Viu)
