Luzhou Airline takes on an important flight mission, which is to transport senior engineers of domestic aircraft to the Xi'an base for flight testing. As Luzhou Airline has previously received a letter of praise from a mother who is afraid of flying, Xu Ce is very satisfied with Cheng Xia, so he arranges for Cheng Xia to act as co-pilot with Captain Jiang Tao. Ai Jia in the cabin also arranges for Li Yu Heng and Xia Zhi to participate in this business flight mission together. As a result, both of them are very excited to have such a rare opportunity to practice their skills. (Source: Viu)
