Episode 9 recap: Su Yu Xuan investigates the spice poisoning incident at the Gui Pei Ge.

Shan Dan Dan and Pei Pei discuss their ideals, wanting to become the best jade experts and open a shop with Shan Shuang Shuang in the future to live the life they aspire to. Pei Pei wants to help Shan Dan Dan realize her dream so that she won't have to suffer for a living in the future.

Yang's mother finds Su Jue to settle accounts, as there was an issue with their broken jade that has caused a lot of trouble for their business. Su Jue quickly takes Shan Shuang Shuang to investigate. Su Jue tells his uncle Wang the good news that Su Yu Xuan's business is doing very well, and praises Shan Shuang Shuang's good ideas that crushed Gui Pei Ge, as they can no longer sell their products and have been criticized by everyone for plagiarism.

However, Shan Shuang Shuang feels that while it's good for Su Yu Xuan, it's unfair to her sister Shan Dan Dan. After Shan Shuang Shuang and Su Jue leave, Wang recalls the incident with Guan Yu's phoenix crown years ago, when Shan Shuang Shuang's father was poisoned and died, leaving his daughter for Wang to take care of.

Shan Dan Dan kneels in front of Pei Qin's door early in the morning to apologize. Pei Qin thinks the broken jade idea was not wrong, they just reacted too slowly at Gui Pei Ge, so it's fine to pay some compensation, as long as Shan Dan Dan and Pei Pei can produce the fragrant jade stones well.

Shan Dan Dan is touched by Pei Qin's tolerance and accidentally falls down, causing a commotion. She goes back to her room to rest, and Pei Pei takes good care of her. Pei Pei has already prepared the fragrant jade stones, so as long as Shan Dan Dan rests well, everything will be fine.

Pei Pei feels their family's funds are tight, so they need to save everywhere. Pei Qin thinks it's tough but manageable. Some people go to Gui Pei Ge to attack them, as their fragrant jade stones caused their family members to have rashes and be unable to move. Pei Pei and Shan Dan Dan rush to deal with the problem but get beaten by the crowd. Pei Pei quickly protects Shan Dan Dan from being hurt.

Pei Pei promises to provide a good solution to barely calm the situation. Soon, some of Gui Pei Ge's shops are affected. The family worries they may not be able to operate. That's when Tan Qing He arrives, as all the spices are supplied by his family. However, Tan Qing He believes their natural spices are non-toxic and harmless.

Shan Dan Dan needs to investigate thoroughly to give everyone an explanation, and Tan Qing He will also investigate to provide an explanation.

Please instruct the manager to thoroughly investigate the matter, hoping to overcome this difficulty. Su Jue and Manager Wang were also surprised by what happened at Qipei Pavilion, and although they both think it was Shan Shuang Shuang's doing, Shan Shuang Shuang claims she would never do anything to harm lives. The few of them are suspicious of each other but none of them actually did it. Su Jue feels they should investigate thoroughly, in case such an incident happens in their own household. Shan Shuang Shuang actively offered to investigate the matter.

Pei Pei took Shan Dan Dan to the streets to investigate the case. Pei Pei was worried that as a woman, Shan Dan Dan would not be convenient, so she had her dress as a man, but it was pointless as people on the street immediately recognized Shan Dan Dan as a woman. Pei Pei also warned Tan Qinghe to be careful with Shan Dan Dan, but Tan Qinghe felt his days have been unpleasant since Shan Dan Dan went to Qipei Pavilion, leaving Pei Pei at a loss.

Soon, Shan Dan Dan found a clue and hurriedly returned to share it with Tan Qinghe and Pei Pei. The spice shop Qipei Pavilion and Su Yuxuan were both using the same type of spice, but while nothing happened to Su Yuxuan's jade carvings sold from Qipei Pavilion, the victims fell ill. They unanimously suspected Su Jue, but Pei Pei felt such an obvious wrongdoing was unlikely for Su Jue, as it would not benefit them, so there must be another culprit.

They arrived at the door of the poisoned family, wanting to investigate who was behind this. Shan Dan Dan had Pei Pei disguise herself in a hat and cloak to try to bribe information out of them, but the family refused to admit anything. Pei Pei had no choice but to directly question them about framing Qipei Pavilion, angering the master of the house and getting her chased away.

Just as Pei Pei left, a group came to demand protection fees from the master, but he could not pay. Pei Pei felt if he had taken money to frame Qipei Pavilion, he would not be unable to pay the fees, so he may have been the victim. Pei Pei led a few people to drive the protection fee collectors away, and the master was very grateful to them.

The master explained they had been living a difficult life, and wanted to buy his wife a jade bracelet as a gift, but it ended up poisoning them. Shan Dan Dan examined and found the poisoning may not be caused by the spice alone, so they need to further investigate the cause.

Su Jue and Shan Shuang Shuang went to Qu Lanzhong's shop to inquire about whether the spice was poisonous. The victims had bruised skin, so they wanted Qu Lanzhong to help explain, but he suspected it was not severe poisoning, but rather someone had used a curse on them. Fortunately, Qu Lanzhong knew how to treat it.

Just as Pei Pei's group was about to head back, they were blocked by the protection fee collectors. Outnumbered, Pei Pei quickly sent Alu to call for reinforcements so they could face them.
