Episode 16 recap: The mistress interfered with Xia Chu's relationship and provoked her with words.

Qin Da Di finally found time to visit his son, and he was very pleased to see that his son's legs were gradually regaining feeling. The son told Qin Da Di that everyone was now discussing whether China's carrier-based aircraft could take off from aircraft carriers. Tao Si Yong and Yu Tao discussed that this was a heavy responsibility, and they were not sure if Qin Da Di could take it on.

Similarly, Wu Xiao had a wish - as long as it could help her son's illness recover, even just a little bit, she would be willing to do anything. Because Qie Cheng was sent to the hospital due to a car accident, Xia Chu considered it carefully and still came to visit, but was accused by Qie's mother of not caring about her unmarried fiancé at all.

Xiaoxiao actively provoked Xia Chu, telling her to let go soon, as they were just not suited for each other. Before the test flight, Xie Zhen Yu went to find his mentor Wu Jing Tian, and Yu Tao went to the hospital to visit his grandfather Yu Zhao Nian. Under the guidance of the two senior experts, they gained new insights.

Xia Chu unexpectedly discovered photos in her fiancé Qie Cheng's circle of friends, showing him and his secretary Xiaoxiao wearing matching bracelets and shoes. Due to this important discovery, Xia Chu was uneasy the whole day, suspecting that the two had an unusual relationship, which even Xie Zhen Yu and Liu Ni Na noticed.

Xie Zhen Yu actively cared about Xia Chu's situation to thank her for her previous guidance, but Xia Chu was very resistant and unwilling to talk to him. In contrast, when Liu Ni Na found out, she was indignant and stood up for Xia Chu. She originally wanted to call Xiaoxiao to get information, but Xia Chu decisively refused, believing that Qie Cheng also had responsibility in this matter.

Xie Zhen Yu seriously considered the stall problem to prevent aircraft from crashing into mountains, and made detailed calculation formulas, hoping that Qin Da Di and Yu Tao would be on the same page as him. Later, Xie Zhen Yu and Yu Tao submitted their respective plans, and it turned out that their ideas were in perfect agreement.

Regarding who should conduct the first test flight, Qin Da Di suggested following the commander's arrangement, but Yu Tao disagreed and competed with Xie Zhen Yu to be the first test pilot. Soon, Yizhen Bang brought in two CEOs, Zhou and Liang, who expressed approval for the B40B course test plan proposed by the test flight team, and praised the team for having real talent who could solve even the most difficult problems.

However, Commander Zhang still had some concerns, feeling that the test itself was not just a theory, but mainly depended on the pilots' reactions, and proposed conducting extensive simulation training before the actual flight. Yizhen Bang agreed, and said he would listen to the expert team's opinion on the order of the test flights. After Kang Yan Cheng and others finished checking on Xie Zhen Yu, they couldn't wait to inquire about his situation and delivered the chocolate they had bought for him.

The atmosphere of intimacy between the two quickly heated up. Kang Yan Cheng returned to the dormitory and revealed to Xie Zhen Yu that he was interested in Liu Ni Na. Xie Zhen Yu supported his brave brother in pursuing love and assured that he would not interfere. Xie Zhen Yu and Yu Tao's test flight went very smoothly. Qin Da Di had everyone try flying, and asked them to share their thoughts.

That night, Qin Da Di called his wife Wu Xiao and learned that their son's leg was regaining sensation, indicating he was on the path to recovery. Wu Xiao told Qin Da Di that he was the pride of the family, which deeply moved Qin Da Di. The next day, Qin Da Di summoned Yu Tao and stated that the first B40B training flight test would be entrusted to Xie Zhen Yu.

Although Yu Tao did not object, he could not hide his disappointment, fearing that in the future he would always have to let Xie Zhen Yu take the lead to aid his growth. Yu Tao requested that if Xie Zhen Yu failed this test flight, the next one would be his turn to be the first test pilot.

On the day of the test flight, all departments were ready and closely monitoring Xie Zhen Yu's results. Xie Zhen Yu did not disappoint, with both the pilot and aircraft returning unscathed. Yí Zhèngbāng was delighted and decided to request a merit citation for the test flight team, indicating the first stage of test flights had been completed and they would move on to the air test phase.

Qin Da Di gathered all the members and announced that the day after tomorrow, Yu Tao and Geng Jian Lin would demonstrate the flights, then they would begin the first wave of test flights in order. Wu Qiang felt they were all seasoned veterans, and the simulation training could be completed in half a day, so they could directly proceed to test flights in the afternoon. Qin Da Di confirmed there were no objections and happily agreed.

The subsequent test flight process went very smoothly, with the previous pilots all successfully taking to the skies. Until Kang Yan Cheng, during the acceleration phase, seemed to encounter a barrier in front of him, briefly startling him before exclaiming excitedly.

When Wang Xiao Mao was preparing to take off, he suddenly stopped, and everyone rushed to inquire. Wang Xiao Mao said he saw a wall. In response, medical personnel immediately sent Wang Xiao Mao to the hospital for examination. Yu Tao volunteered to fly in Wang Xiao Mao's place, but in the next moment, he too suddenly stalled and stopped, citing the same wall.

Qin Da Di was about to investigate further when Jiang Hai offered to test fly in his place. Xie Zhen Yu, through Kang Yan Cheng, confirmed the existence of the wall and warned Jiang Hai to stop immediately if he felt anything amiss. As expected, whether it was Jiang Hai or Xie Zhen Yu, they could see the wall during the takeoff phase.
