Episode 10 recap: The princess committed suicide.

He Yi Jing felt very guilty because she had promised to protect Mo Lin Lang and ensure her safety, but every time she ended up putting Mo Lin Lang in danger. In order to comfort He Yi Jing, Mo Lin Lang pretended to slap her playfully, but accidentally hit her too hard, causing He Yi Jing to cough. Mo Lin Lang quickly apologized.

He Yi Jing naturally told Mo Lin Lang that they were on the same side and didn't need to be so polite. Mo Lin Lang was actually touched and thought He Yi Jing looked beautiful when she smiled, so she encouraged He Yi Jing to smile more in the future. He Yi Jing said she would do her best and then asked Mo Lin Lang if there was any way to escape. Mo Lin Lang mentioned something about "The Shawshank Redemption" and suggested digging a tunnel to escape.

Mo Lin Lang was happy to go out, even mentioning something about being number one on Douban (a Chinese social media platform). He Yi Jing looked at herself covered in mud but didn't say anything. He Yi Jing found the princess, who had already guessed that Le Wang wanted to take action again. The princess told He Yi Jing that ever since He Tingjian came to Le Dong, he had changed completely. She overheard him conspiring with a spy and learned that he had come to Le Dong to take over its army.

The princess knew that her husband had been feeding her contraceptives for over ten years. She was also afraid that her child would become her weakness. Now, she had the military orders in her hands. When He Yi Jing disappeared, He Tingjian became furious and refused to believe that she had gone into a dog hole. He Tingjian knew that the princess had hidden the military orders. He Yi Jing told He Tingjian that the Empress had already gone underground to wait for him. He Tingjian was shocked and saddened by the news of the princess's death.
