Episode 6 recap: Shang Guan Qian cleverly probes Gong Shang Jue, and the truth about the jade pendant comes to light.

Yun Wei Shan was going to accompany Gong Zi Yu to the entrance of the back mountain, but she was stopped by Gong Zi Shang and Jin Fan. In a moment of slip of the tongue, she mentioned that outsiders were not allowed to enter, but quickly corrected herself, saying that idle people were not allowed. She explained that there were numerous traps and only those with strong martial arts skills would dare to venture there. Gong Zi Yu did not allow anyone to accompany him and personally went to the back mountain.

Gong Zi Yu arrived at the back mountain, where he was going to undergo the Three Realms Trial.

Yun Wei Shan returned to her room once again to search for any traces left by Shang Guan Qian. Shang Guan Qian obtained the gift she had given to Gong Shang Jue, and Gong Yuan Zheng mentioned that his brother did not like such flashy golden items. Shang Guan Qian went to the peaceful courtyard intending to greet Gong Yuan Zheng, but he blocked her way, curious about the scheme she employed to make his brother so concerned about her. Gong Yuan Zheng tested Shang Guan Qian's determination by presenting a worm to her, and she swore her sincerity to Gong Shang Jue while holding the worm directly.

Shang Guan Qian quietly used a silver needle to test the food in front of her, meticulously inspecting everything. Gong Yuan Zheng carefully tended to his flowers and suddenly noticed that his hidden weapon was missing from his waist. He suspected Shang Guan Qian and ordered a search of her room. Shang Guan Qian asserted that she also had dignity. At that moment, Gong Shang Jue arrived, and Gong Yuan Zheng mentioned that his hidden weapon was different from others', fearing the consequences if it fell into the wrong hands. Gong Yuan Zheng wanted to search Shang Guan Qian further, but she claimed to be an innocent daughter of a respectable family. They found a jade pendant on Shang Guan Qian during the search, and Gong Yuan Zheng still doubted her. However, at that moment, one of his subordinates brought a hidden weapon pouch found by the riverbank and handed it to Gong Yuan Zheng. Reluctantly, Gong Yuan Zheng apologized to Shang Guan Qian, and Gong Shang Jue returned the jade pendant to her. She claimed that the pendant originally belonged to him, leaving Gong Shang Jue puzzled about how it ended up in her possession.

Gong Shang Jue realized that the hidden weapon pouch should not have been easily dropped, but without evidence, he wouldn't take action without absolute certainty, just like a lion wouldn't hunt without absolute confidence. Through this incident, Gong Shang Jue guessed that Shang Guan Qian would become increasingly intriguing, and it was highly likely that someone had tampered with his hidden weapons. Within the palace gates, there might be someone without a blade. Yun Wei Shan found Gong Yuan Zheng's hidden weapon pouch by the riverbank, guided by Shang Guan Qian's markings. She falsely claimed to have found something belonging to Gong Zi Yu and had it returned to Gong Yuan Zheng through his men.

Gong Zi Yu recalled how he was bullied by his brothers and called a wild seed when he was young. He cried and searched for his mother, but she did not comfort him. Gong Shang Jue held the jade pendant and remembered how he once saved Shang Guan Qian in a desolate village, where he accidentally dropped the pendant. Yun Wei Shan encountered Gong Zi Yu while wandering around, and he worried that she wouldn't be able to sleep in a new place. He offered her a calming soup. He had moved to his father's room and missed his father even more. Gong Zi Yu used to cry a lot when he was young, and Yun Wei Shan mentioned that she also used to cry a lot as a child. But her younger sister would sing songs to comfort her, and as long as she heard her sister's singing, she would no longer be afraid. However, they had not seen each other since her sister took on a mission at the palace gates. Yun Wei Shan returned the fox fur to Gong Zi Yu, assuming it was something he cherished, and the pendant was a carefully selected gift from Gong Hong Yu to Gong Zi Yu.

Yun Wei Shan acknowledged Gong Zi Yu's genuine kindness towards her, but she felt that she would always disappoint him. Shang Guan Qian went to the kitchen and asked Yun Wei Shan when she would enter the mountain. The back mountain was mysterious, and many servants were unaware of its details. If Yun Wei Shan could gather information about the back mountain, it would be a significant achievement. Yun Wei Shan assured them that she would find out about the back mountain but couldn't reveal the specific method. Gong Zi Yu asked Jin Fan to disclose the details of the Three Realms Trial, but he was unable to do so. Two guards overheard rumors about an explosion in the front mountain and discovered that it was caused by the young miss conducting experiments. At that moment, Xiaohei, a small black creature on a tree, heard about it and wanted to go play in the front mountain.
Yun Wei Shan helped prepare Gong Zi Yu's luggage, including several medical items. She also prepared a medicinal wine to ward off cold and dampness, as well as some snacks. Worried for his safety, she also sent him her own sachet. Yun Wei Shan felt that these things were what she should do because they belonged to him. However, she felt shy and didn't express it explicitly. Gong Zi Shang continued to research her findings and patiently awaited results, but just as she was about to uncover the lid, another explosion occurred. Xiaohei saw the residue in the pot and directly commented that the sulfur ratio was incorrect, as his grandfather was involved in making fireworks and he had some knowledge about it.

Yun Wei Shan wanted to accompany Gong Zi Yu to the entrance of the back mountain, but she was met with refusal from Jin Fan and Gong Zi Shang, as outsiders were not allowed in. Jin Fan noticed the worry on Gong Zi Yu's face when he entered the back mountain and guessed that there might be a life-threatening danger inside. She speculated that the first challenge would test one's internal strength. So, she used the excuse of rescuing Gong Zi Yu to persuade Gong Zi Shang to help her enter the back mountain, stating that she was not an outsider but Gong Zi Yu's wife.
