After investigating the Yanju-dong poisoning and murder case, Korea University Law School began a mock trial. Jiang wore pajamas and led A as the presiding judge, and other elite law students also participated. Among them, defense lawyer Jiang Yin B was overbearing, leaving witnesses and prosecution lawyers speechless.
Han Junhui played the role of a prisoner during the trial, and especially noticed that Professor Xu, who was presiding over the trial behind him, was a little uncomfortable. During the 30-minute break, Professor Xu returned to the office. At the end of the class, no one saw Professor Xu, so the female student playing the role of bailiff went to check. Unexpectedly, Professor Xu died in the office, foaming at the mouth.
The police quickly sealed off the scene, and Yang Zongxun went to the scene to assist in collecting evidence and found suspicious tea leaves, test papers, and last words similar to suicide. Yang Zongxun used to be a prosecutor, but now he is a law school professor and is a colleague of Professor Xu.
