Episode 6 recap: Zhou Yu refused to change his swimming technique, and as a result, he couldn't make a breakthrough in his performance.

The list of first-team members was announced, and Hao Di gave the list to Gu Luo and Liang You Guang to select the members for their respective teams. Gao Feng and Wu Hao joined Gu Luo's team, while Zhou Yu and Hu Jing Tian joined Liang You Guang's team. After announcing the team members, Gu Luo announced that there would be a competition after the grouping called the "Battle of Supremacy." Liang You Guang, after the meeting, blamed Gu Luo for scheming against him and not informing him about the competition when selecting the team members.

After a verbal exchange between Liang You Guang and Gu Luo, Gu Luo went to arrange the training and developed training plans for each individual. Gu Luo started training, while Liang You Guang leisurely waited for the players to gather without any rush. Zhou Yu and the others were ready and seemed eager to get started. Liang You Guang explained that in his team, everyone was just a number, and today's task was for everyone to swim five kilometers.

Zhou Yu and the others had objections to swimming five kilometers, so Liang You Guang decided to have a race. Whoever won would have their distance reduced by two kilometers. He also asked Zhou Yu to observe the arm strokes of the other swimmers during training. During physical training, Gu Luo mentioned Zhou Yu's issue to Liang You Guang, who proudly stated that he had a keen eye for selecting people and showed no concern about falling behind.

While Gu Luo trained his team intensively, Liang You Guang engaged in game-based training, causing various reactions and raising objections from Gu Luo. Through repeated training sessions, Liang You Guang made Zhou Yu aware of his problem and reminded him that he must change his arm stroke to improve his performance. Gu Luo believed that Zhou Yu was too stubborn and that he couldn't handle him, but Liang You Guang remained confident in his ability to guide Zhou Yu.

The training volume was very intense every day. Wu Hao, due to a shoulder injury aggravated by the heavy training, went to the clinic as soon as it ended, while Zhou Yu continued training. Hu Jing Tian and Gao Feng returned to the dormitory first and started chatting about training. They couldn't help but gossip about Liang You Guang and Gu Luo, pointing out their ongoing rivalry because they both liked the same woman.

Gu Luo pulled Liang You Guang to the swimming pool and discussed Zhou Yu's issue. He believed that Zhou Yu was too stubborn and refused to change his swimming posture, making it difficult for him to improve his performance. Liang You Guang told Gu Luo that Zhou Yu's postures were taught by his father, and it was natural for Zhou Yu to be attached to them. He asked Gu Luo to give Zhou Yu some time. While preparing to leave the changing room, Zhou Yu unintentionally overheard the conversation between Gu Luo and Liang You Guang, which reminded him of his father teaching him to swim when he was young.

Zhou Yu seriously pondered the words of Gu Luo and his father. The next morning, he went to find Liang You Guang to tell him that he would win the competition and prove that his method was correct. Gu Li was sent to the sports school for an interview. She first interviewed Liang You Guang and then went on to interview the athletes. Wu Hao and Hu Jing Tian briefly discussed their experiences of learning swimming, but before they could finish, Gu Li spotted Zhou Yu passing by and chased after him for an interview. Zhou Yu simply stated that he liked swimming without any particular reason and didn't say much, making it difficult for Gu Li to continue the interview.

Gu Li interviewed Gao Feng, and they had a pleasant conversation. Gu Li couldn't help sharing her past desire to become an athlete with Gao Feng. During the next round of testing, Zhou Yu initially caught up with Gao Feng while swimming but soon slowed down. In the end, he didn't prove, as he had thought, that his father's teaching method was correct. Zhou Yu failed, and he sat in the changing room of the swimming pool, lost in thought about his father's swimming principles for a long time.

Liang You Guang came to talk to Zhou Yu, wanting to convey his message in a lighthearted manner. He teased Zhou Yu a bit, but unexpectedly, Zhou Yu stood up and wanted to leave.
