Episode 16 recap: A single sentence from Gu Chuan sparked a bloody conflict in the martial world.

Gu Chuan informed Guo Dong Li about Liu Lang's intention to go to the Jinwu Sect to kill someone. Guo Dong Li cautioned him to speak softly, but Gu Chuan believed that Changle City would not have members of the Jinwu Sect. Unfortunately, there happened to be a group of people around him who were all members of the Jinwu Sect and heard everything. In order to clarify the situation, Gu Chuan explained that there were infiltrators from the Jinwu Sect in the Qingyang Sect. Unfortunately, members of both sects were present, and they all went to the Li residence to cause trouble.

Changle City was peaceful, but Gu Chuan returned home severely injured. He claimed that his extraordinary temperament had aroused the jealousy and retaliation of the Jinwu Sect. With his last breath, he expressed his final wish: he regretted leaving with money that he hadn't spent yet. Xie Quan Jia assured him that if he survived, she would give him as much pocket money as he wanted. Upon hearing this, Gu Chuan immediately regained his spirit and jumped up, asking everyone present to be witnesses. He demanded a hundred guan in pocket money. Xie Quan Jia initially wanted Liu Lang to teach Gu Chuan a lesson, but at that moment, Liu Lang had already set off for the Jinwu Sect upon hearing that Gu Chuan had been injured by a member of the Jinwu Sect.

Gu Chuan regretted Liu Lang's recklessness and immediately packed his bags to go to the Jinwu Sect. The Jinwu Sect and the Qingyang Sect were meeting at the Wanli Tower to discuss an alliance. A dispute arose between the two factions over who would pay the bill. At this time, Gu Chuan approached Guo Dong Li, hoping to borrow half a guan to go to the Jinwu Sect to find Liu Lang and prevent him from committing murder. Guo Dong Li reminded Gu Chuan that they had thought there were no members of the Jinwu Sect in Changle City, but unfortunately, they were all present. The elders felt that someone was not taking the Jinwu Sect seriously. Gu Chuan explained that there was a Qingyang Sect member who had infiltrated as a spy, and this time they were going to kill the spy. At that moment, a member of the Qingyang Sect stood up and accused Gu Chuan of speaking nonsense.

The members of the two factions wanted to hold Gu Chuan accountable. At this moment, the leader of the Jinwu Sect came out and supported the door, claiming that his martial arts secret book had been stolen by the Qingyang Sect, while the leader of the Qingyang Sect denied it. One of the Jinwu Sect disciples went missing, and once again, it was attributed to the Qingyang Sect. This unknown disciple was actually a spy. As the leader of the Qingyang Sect was explaining, it caused the leader of the Jinwu Sect's old injury to resurface, and he had to return to the mountain for treatment. He entrusted the task of capturing Zhao Jian's disciple to the Qingyang Sect, as only Zhao Jian could verify whether what Gu Chuan said was true or false.

The Qingyang Sect had originally planned to steal the secret book under the pretext of the alliance, but now, due to a single sentence from Gu Chuan, their plans had changed, and it was crucial to find Zhao Jian. Liu Lang knocked out a member of the Jinwu Sect, thinking he was the one who had injured Gu Chuan. Xie Quan Jia explained the whole story to Liu Lang, who had no choice but to search for Gu Chuan. The person who had been knocked out was carried into Gu Chuan's room, but it turned out he was only pretending to be unconscious. As soon as Xie Quan Jia left, he used a secret signal to meet with his contact. He had obtained the secret book but was knocked out by a reckless person. In order to leave the place quickly, he decided to feign illness and extort money.

At this time, members of the Qingyang Sect arrived at the Li residence in search of someone. Ren Shu took out two kitchen knives and asked Xie Quan Jia what they had for lunch. This action raised suspicions among the members of the Qingyang Sect, who accused Xie Quan Jia and the Jinwu Sect of being in cahoots and claimed that, as members of the Qingyang Sect, it was their duty to apprehend this person. Xie Quan Jia wondered why other sects would meddle in their affairs when their own property had been stolen.

Xie Quan Jia led them to the backyard and found that the person was already gone. In order to create a situation where Zhao Jian took Xie Quan Jia away pretending to be him, Ren Shu and Fan Zhongju came to the yard to rescue Xie Quan Jia, but none of the three knew any martial arts. Xie Quan Jia was taken away, and Fan Zhongju went to the yamen (government office) to report the incident.

The impersonator approached Ren Shu as "Mr. Li" and asked to borrow money. She felt that something was amiss at the Li residence today and that one must be cautious. The fake Mr. Li buried a bag of money in the backyard, claiming it was for emergencies and that he was hiding from debt collectors and couldn't stay for long. Seeing this, Ren Shu decided to lend him the money. Liu Lang was searching for Gu Chuan at the Wanli Tower when Xie Quan Jia was brought there. The three of them met, and Xie Quan Jia asked Liu Lang to save her, which made Gu Chuan jealous. Liu Lang had some reputation in the Qingyang Sect and was close to the sect leader. He explained that Xie Quan Jia was his benefactor and questioned how she became Zhao Jian, but he promised to help find Zhao Jian.

When Xie Quan Jia returned to the Li residence, she heard that Ren Shu had given "Mr. Li" three guan of money, which immediately raised suspicions. She suspected that the person was the previous homeowner who owed a lot of debt. All of these problems were caused by Gu Chuan's actions, so he suggested reporting the matter to the authorities. Fan Zhongju went to find an official, and Xie Quan Jia stated that the person was now safe, but there was a new development: she had been deceived and the money was stolen. While the official was taking their statements, they overheard that the Qingyang Sect and the Jinwu Sect were planning to fight. This was a perfect opportunity for Xie Quan Jia to make a contribution.

Zhao Jian and the former homeowner of the Li residence discussed selling the secret book to make money, but Liu Lang overheard their conversation and directly captured Zhao Jian in front of the sect leader. The two factions fought over the martial arts secret book, only to discover that it was the Shanhe Classic. The two sects engaged in a fierce battle in front of the Wanli Tower, attracting a large crowd of spectators. That night, Liu Lang felt guilty and returned home, which inadvertently led to the death of Shilla's top martial artist who ate poisoned fish. In a twist of fate, the emperor used the princess's marriage to resolve the tensions between the two countries, but the real secret book appeared in Gu Chuan's bag.
