Episode 20 recap: Disciple murders Ma Ye.

Yuan Sheng summoned the disciple and expressed his desire for him to kill someone. The disciple agreed and asked how Yuan Sheng wanted the person to die. Unexpectedly, someone suddenly hit the disciple with a stick, leading to a fight between the disciple and that person. However, there were many people on that side, and the disciple was stabbed and fainted. Eventually, they tied up the disciple and threw him into the sea.

Ma Xingbang was also present and extremely surprised. Xiao Yi found the watch left behind by his girlfriend and discovered a video inside. At that time, Xiaowen was tied up, and the two disciples were arguing. The younger brother wanted to take the older brother away, but the older brother was unwilling. The younger brother thought that if they killed the woman, the older brother would leave with him. He expressed his intention to kill her.

Xiao Yi finally found evidence and realized how his girlfriend was before her death, unable to help but burst into tears. Ma Ye had a heart problem and had to come to the hospital for regular check-ups. Initially, everything was normal during the examination, but unexpectedly, the pacemaker malfunctioned and he had to be rushed in for rescue.

Xiao Yi received the news and rushed over. The doctor also found it strange and didn't know the cause. Xiao Yi checked the surveillance and found that there was a janitor pushing a cart passing by at that time. Xiao Yi went to see the control room next to Ma Ye's ward, where some scattered instruments were found.

Xiao Yi questioned Ma Ye, who claimed that he wanted to commit suicide and had hammered his pacemaker with his fist to make it malfunction. Yang, the boss, came to find the disciple, who was having a meal there. Yang asked why the disciple didn't kill Ma Ye, as everything the disciple had said before seemed foolproof, yet they couldn't even kill a patient. It was nothing like what he had said before.

It turned out that Yang had also been at the sea and pulled the disciple out from there.

Because Ma Ye killed Yang Boss's son, Yang Tianyi, Yang Boss wanted to seek revenge on Ma Ye and asked the disciple to help him with the task. Xiao Yi now understands that the instrument in question is an MRI machine. Since Ma Ye has a pacemaker in his body, he cannot undergo an MRI scan as it would deactivate the pacemaker.

The janitor at the time hid the MRI machine in the cart and brought it to the adjacent room. He opened the machine, causing the pacemaker in Ma Ye's body to malfunction. Xiao Yi states that this method of creating an accident is often used by the disciple. Xiao Yi came to confront Ma Ye, stating that Ma Ye had ordered the disciple to kill someone, so he knew it was the disciple who wanted to kill him but didn't dare to speak up.

Xiao Yi says that the next incident will be an accident, and they don't know if it will be similar to this one. Once they capture the disciple, even if Ma Ye confesses, he doesn't want to listen anymore. Ma Ye admits that he heard about a skilled duo of brothers who were good at killing, so he hired them to deal with those two individuals. Xiao Yi believes that since that's the case, the older brother among the disciples at the Yongteng Base was the one they hired. The brothers have a habit of leaving something from the deceased as a memento.

Ma Xingbang comes out and sees his youngest son, Ma Chuan, hanging on the door, causing him to collapse. Xiao Yi approaches Ma Xingbang and asks if he recognizes the disciple, but Ma Xingbang claims he has never heard of him. Xiao Yi points out that Ma Ye almost died yesterday, and today it's his youngest son who died, so he should know what it signifies. However, Ma Xingbang still denies knowing anything.
