Episode 13 recap: Mo Lin Lang was poisoned.

Mo Lin Lang felt despondent. He Yi Jing discovered that the poison on Mo Lin Lang was called "Sui Xin." It was then that Mo Lin Lang realized that the murders were a result of being controlled by this drug. However, He Yi Jing was curious as to why such a poison, which originated from the Jinba Kingdom with which they had hostile relations, would appear here. Moreover, "Sui Xin" was not an ordinary substance, so why would it be found on Mo Lin Lang?

Mo Lin Lang also found it strange. As a newcomer without enemies, who would want to harm a mere servant like herself for no reason? He Yi Jing speculated that perhaps someone wanted Mo Lin Lang to get close to a person they intended to approach. Fu Feng believed that He Yi Jing might be in danger.

Mo Lin Lang suspected that if it were indeed He Yi Jing, the culprit would strike again. Qian Jing Yi was angry at the failure of their plan. She was frustrated with her father's warning not to act rashly. The incident involving Liu Zi Yuan had entangled many people, and now was a dangerous period where they should avoid attracting attention.

Qian Jing Yi regarded Liu Zi Yuan as incompetent, more a waste than a loss. He Yi Jing had been by Mo Lin Lang's side all along. When Mo Lin Lang woke up, she asked He Yi Jing if the culprit had been found. He Yi Jing informed Mo Lin Lang that she did not have an episode the previous night.

He Yi Jing wanted to take Mo Lin Lang away, but Mo Lin Lang believed that she couldn't simply leave like that, as it would put He Yi Jing in danger. At this moment, Fu Feng found a way to stimulate the poison in Mo Lin Lang's body. However, He Yi Jing hesitated upon hearing this, reluctant to put Mo Lin Lang in jeopardy.

Fu Feng informed He Yi Jing that only she could do it. He Yi Jing knew that if she failed, Mo Lin Lang would become a fool. Mo Lin Lang reassured He Yi Jing, and He Yi Jing triggered the poison in Mo Lin Lang's body. Mo Lin Lang grabbed He Yi Jing's neck, then turned and walked away.
