Episode 16 recap: Xing Shi discovered the secret of changing identities, and Liu Jiao Yuan was plotting again.

Xing Shi sent Mei Yu Shan back to the inner palace, and Su Ruo Mei was already waiting at the door. When she saw Mei Yu Shan return, she came forward and questioned why she had knocked her unconscious. Mei Yu Shan explained that the two of them had accidentally bumped into the door and fainted.

Soon, Xiao Dou Zi also returned to the inner palace, but he was being carried by the Crown Prince. Su Ruo Mei's expression immediately changed, and seeing that Xiao Dou Zi didn't care about the two of them at all, she threatened to report to the Empress Dowager.

Mei Yu Shan took care of Xiao Dou Zi's injuries, and in order to make chicken soup, she even directly put a live rooster into the pot. Even Nan Bei couldn't stand it and wiped Xiao Dou Zi's face in a cursory manner, like wiping a table. Nan Gong Yao saw that Mei Yu Shan couldn't take care of people at all, so he directly took Xiao Dou Zi to the Eastern Palace to recover.

Since Xiao Dou Zi went to the Eastern Palace, the best lingzhi were sent there. Xiao Dou Zi's nosebleeds were improved, but those tonics were not what he liked to eat. Xiao Dou Zi stated that if they really wanted to supplement his body, they should make the food he liked, and he specifically mentioned stinky tofu and lamb offal soup.

Roasting stinky tofu and simmering lamb offal soup in the Eastern Palace guest room, anyone who heard it would think it was outrageous. But Nan Gong Yao directly approved it. As for the memorials submitted by officials, some suggested cancelling the rural learning examination, and some requested funding to repair bridges every year, but they were all rejected.

In the elegant Eastern Palace, people were responsible for cooking the lamb offal, and both of them were so nauseated by the smell that they vomited.

After being allowed to eat the lamb offal, Xiao Dou Zi had a series of strange and unusual ideas. Nan Bei reported them one by one, and Nan Gong Yao said that as long as Xiao Dou Zi didn't dismantle the Eastern Palace, he could do whatever he wanted.

On the way back to the Eastern Palace, Nan Bei reported that the few people who had been interrogated for inciting execution had committed suicide by poisoning themselves. Nan Gong Yao said that he actually knew the behind-the-scenes instigator, and when the officials submitted memorials to impeach him, everyone spoke with conviction, except Liu Jiao Yuan, who remained silent, indicating his guilty conscience.

After finishing speaking, a strong stench was detected, which was the smell of the stinky tofu that Xiao Dou Zi was roasting.

Lingxiao suggested telling the Crown Prince about the matter of Mei Yu Shan's maid being Princess Sheng Dongguo, but Bai Ye disagreed. If it was confirmed, Xiao Dou Zi, their good friend, and the entire Mei family would be implicated, so Bai Ye needed to find another way to keep Xiao Dou Zi from being implicated.

Xiao Dou Zi had basically recovered, but the Crown Prince required him to fully recover. Tai Fu concocted a special ointment, saying the potency of his spirit insect drug would be strongest on the night of the full moon. Hearing this, Xiao Dou Zi thought about returning to the young lady's chambers to try exchanging bodies with Mei Yu Shan again.

Xing Shi delivered medicine to Mei Yu Shan daily and asked about the three sworn fathers, but Mei Yu Shan couldn't explain clearly. Xing Shi then took out some stinky tofu he bought from Black Dog Alley. Worried about exposing her identity, Mei Yu Shan took only a small bite before going out to get tea. Xiao Dou Zi had returned to the room first and seeing the stinky tofu, eagerly ate several pieces, even commenting on Aunt Xing's cooking skills. Xing Shi, hiding behind the screen, accidentally dropped his handkerchief. Xiao Dou Zi thought it was Mei Yu Shan's and started loudly planning to try the body exchange again on the night of the full moon. It was only later that Mei Yu Shan entered the room, and Xing Shi had to take his leave.

Liu Jiao Yuan began memorializing again about Mei Yu Shan causing chaos in the Eastern Palace. Xiao Dou Zi accidentally saw this and was deeply saddened. While walking, he almost stepped on Tai Fu's medicinal ingredients, but Bai Ye happened to pass by and held Xiao Dou Zi in his arms to prevent another injury. Seeing this, Nan Gong Yao flew into a jealous rage and immediately had Xiao Dou Zi brought back to the Eastern Palace.

Xing Shi asked the general about the matter of the Moon Spirit Pearl body exchange and got a definitive answer. Xiao Dou Zi was packing to leave the Eastern Palace, and Nan Gong Yao, thinking Xiao Dou Zi had fallen for Bai Ye, had Nan Bei escort Xiao Dou Zi back to the young lady's chambers. From then on, Nan Gong Yao became distracted during his studies.
