Episode 11 recap: Shan Dan Dan was promoted to Second Steward for her contributions in solving the case.

Shan Dan Dan got separated from Pei Pei while being chased by several women, and Pei Pei quickly searched for Shan Dan Dan's whereabouts. Fortunately, Shan Shuang Shuang, Shan Dan Dan's older sister, found and protected her. However, the women soon lost their energy and dispersed.

Su Jue and Pei Pei examined the women and found that the jade artifacts did not have the seven-colored threads, but the symptoms indicated they were poisoned by a yin-yang voodoo grass. This strange situation made everyone wonder if someone had tampered with the items and taken the seven-colored threads. Su Jue led a group to the seven-colored thread shop to investigate, but the shop owner already knew about the poisoning incident, stating it had nothing to do with their seven-colored threads. At that moment, Pei Pei noticed someone peeking from outside, looking like Cui Liu, who quickly hid when spotted.

Pei Pei asked the shop owner if he had hired any temporary workers, and the description matched Cui Liu. The city lord summoned the Su and Pei families and accused them, but they explained that they had found the voodoo grass. Angered, the city lord gave them one more day to solve the case, threatening them with execution if they failed.

That night, the city lord had guards detain the Pei family head, Pei Qin, as a hostage, and the Su family was also ordered to hand over Su Jue. Although Steward Wang wanted to replace them, his offer was rejected. Shan Dan Dan secretly changed the name on the Pei family head's detention order to her own, which Pei Pei tried to stop, but Shan Dan Dan was willing to sacrifice everything for the Pei family's trust, touching Pei Pei, though her actions were not approved.

At that time, the family members captured Cui Liu, and Pei Pei directly confronted her, leading Cui Liu to confess that she had gone to a temple to pray and wish for Shan Dan Dan to leave Pei Pei out of jealousy, and a masked person had appeared, telling her to work at the seven-colored thread shop and mix the threads with poison.

Cui Liu had never seen the masked person's face, as the meetings were always at the temple. Shan Dan Dan tried to lure the masked person out. Su Jue also investigated the origin of the poisoned seven-colored threads, finding they came from the Western Regions, and that nine years ago, there had been people growing the voodoo grass in Xiu Shui City, so she sent people to investigate there.

Worried that this could be the end of the Su Yuxuan family, Su Jue arranged for Shan Shuang Shuang to leave with all the family's wealth, but Shan Shuang Shuang reassured Su Jue, saying that her sister Shan Dan Dan and Su Jue were her greatest concerns.

Cui Liu went to the temple to meet the masked person, wanting to back out now that the situation had escalated, but the masked person tried to kill her to silence her. Luckily, A Liu, who had been lying in wait, rushed to rescue her, but he was no match for the masked person. Pei Pei and the others then arrived, determined to unveil the masked person's true identity.

Pei Pei and Shan Dan Dan did not expect that the masked person was actually Tan Qinghe. Pei Pei analyzed Tan Qinghe's previous actions, and found that every time there was a clue, Tan Qinghe would find an excuse to leave, and the spice and jade business was also suggested by Tan Qinghe, so he was the biggest suspect. The masked person thought that although Pei Pei had many people, he did not take them seriously, and one person was enough to deal with them, so he took the initiative to attack and try to eliminate them all. At this time, Su Jue also brought people and arrived, and they had also found the relevant clues, knowing that the behind-the-scenes was Tan Qinghe.

At the critical moment, the masked person released many butterflies, and everyone was immediately stunned by the poison gas released by the butterflies, but Shan Shuang Shuang was fine. After everyone fainted, Shan Shuang Shuang flew straight towards the masked person and killed him with a sword. Although the masked person's kung fu was very high, he was no match for Shan Shuang Shuang at that time, and he fainted after being stabbed in the abdomen.

Shan Shuang Shuang gave the antidote to everyone, and they all woke up. Unexpectedly, the masked person also woke up, and just as he was about to fight again, Tan Qinghe also arrived with people, which surprised everyone about the identity of the masked person. The masked person took off his mask, and it turned out that he looked exactly like Tan Qinghe.

Shan Dan Dan had initially suspected that the behind-the-scenes person was Tan Qinghe, but she was not sure, because the Tan Qinghe they were interacting with now was a bit different from the original Tan Qinghe. After various comparisons and analyses, they discovered that the masked person was actually Tan Qinghe's twin brother, named Tan Qingbo. Tan Qinghe asked his brother to stop, but Tan Qingbo felt that he had his own ideals to achieve and would not just survive like them.

It turned out that the two brothers were the sons of the leader of Shuishui City, and the reason why Tan Qinghe was doing intelligence work in Yuncu City was that he was not ambitious enough, which angered Tan Qingbo. Shuishui City had long been oppressed by Yuncu City, and it was only thanks to the spice and jade business that they were revived. However, when the mayor of Yuncu City learned about it, he directly imitated and competed for the business. After many teachings, Tan Qinghe still did not want to live that kind of competitive life, so Tan Qingbo had no choice but to kidnap him and impersonate Tan Qinghe to carry out his plan.

Su Jue and Pei Pei wanted Tan Qingbo to confess voluntarily and plead for mercy from the mayor, but Tan Qingbo was determined to fight to the end even at the cost of his life. Tan Qinghe hurriedly begged his brother to repent, but at that moment, the Yuncu City officials arrived, and Tan Qingbo did not compromise, but committed suicide in front of everyone. Shan Dan Dan was very concerned about Tan Qinghe's situation, and although the matter was over, she still deeply felt the pain of losing a loved one, so she decided to visit him in a few days.

Pei Qin was very grateful to Shan Dan Dan, and since Shan Dan Dan had been to their house, they had always been able to avert crises. So he directly promoted Shan Dan Dan to be the second manager of Qipei Hall and the chief jade appraiser. The mayor also highly praised the Pei family, and their sales have far exceeded the Su family, which made Shan Dan Dan very happy.
