Episode 12 recap: Mo Lin Lang was falsely accused of murder.

Mo Lin Lang was imprisoned for the murder, and He Yi Jing visited the prison to see Mo Lin Lang. Fu Feng informed He Yi Jing that the victim was a hunting guard, and according to the night guards on duty, Mo Lin Lang was indeed seen leaving with the deceased last night, which made Mo Lin Lang a strong suspect.

He Yi Jing didn't believe this news and ordered Fu Feng to continue investigating and find any possible clues. Mo Lin Lang felt disappointed that she couldn't prove her innocence, but she knew she was not the killer. He Yi Jing firmly believed that Mo Lin Lang was incapable of committing murder.

Since Mo Lin Lang couldn't prove her innocence, she decided it was time to reveal her identity to He Yi Jing. He Yi Jing learned that Mo Lin Lang was not from the Shunqing Kingdom but a forensic expert from many years in the future, which explained her knowledge of peculiar things.

He Yi Jing finally understood why Mo Lin Lang knew so much, and as long as Mo Lin Lang claimed innocence and not having committed any illegal acts, He Yi Jing promised to protect her. The Emperor suspected Mo Lin Lang, especially because the murder occurred during his hunting event, and he couldn't be sure that Mo Lin Lang didn't have ill intentions towards him.

He Yi Jing assured the Emperor that Mo Lin Lang was innocent. The Emperor decided to give He Yi Jing a chance, and He Yi Jing requested Mo Lin Lang's assistance, which the Emperor agreed to. Mo Lin Lang was thrilled that He Yi Jing had obtained an opportunity for her to prove her innocence.

Although Mo Lin Lang hadn't found any suspicious points, He Yi Jing believed they still had two days and was confident they would succeed. He Yi Jing discovered a strange red mark on Mo Lin Lang's hand.
