Shen Kai's trick can be described as clever, after his parents-in-law lived in his house for a few days, Shen Kai's affection, care and thoughtfulness to his beloved wife made his parents-in-law very satisfied with Shen Kai. Shen Kai naturally also secretly observed the expressions of his parents-in-law, he was secretly proud in his heart, he behaved so perfectly, which greatly reduced the chance that his parents-in-law would doubt him after Xiao Keyi's sudden death in the future.

After his parents-in-law had to leave due to work, Shen Kai's wife-killing plan started the second part.

He himself was really on a business trip, and he deliberately traveled with several people who inadvertently gave him a witness. According to his arrangement, Xi Mengying had secretly infiltrated Shen Kai's house with the key to Shen Kai's house that was quietly prepared.

Xi Mengying is secretly pretending to be a ghost, how can Xiao Keyi, who has been greatly stimulated, bear it? So, Xiao Keyi was admitted to the hospital again.

And Xiao Keyi's words and deeds convinced the doctor that Xiao Keyi was suffering from schizophrenia. At this point, Shen Kaitu's revenge for murdering his wife and cheating on insurance while cheating on his wife's online chat is ripe.

What everyone can see is that Shen Kai takes meticulous care of his beloved wife, and even does not hesitate to spend a high price to invite Xi Mengying, a well-known local psychiatrist, to serve as Xiao Keyi's personal doctor, not only responsible for Xiao Keyi's psychiatric treatment, but also responsible for Xiao Keyi's diet and daily life.

Shen Kai's co-conspirator, Xi Mengying, naturally entered Xiao Keyi's house so reasonably, and the Grim Reaper had already opened his arms to Xiao Keyi.

Xiao Keyi used his professional knowledge to skillfully use the variety and dosage of psychotropic drugs, so that Xiao Keyi got closer and closer to the real psychopath.

Although Shen Kai's family is located in Qingshixia Villa, a wealthy area, it is a small place and a mountainous area after all, and people generally believe in superstition. This provided good natural conditions for Shen Kai to use the theory of ghosts and gods to kill Xiao Keyi, and Shen Kai didn't want to do it, but the debt crisis became more and more serious, forcing him to almost collapse, and he didn't have time to wait for Xi Mengying to use drugs and pretend to be ghosts to drive Xiao Keyi crazy and finally cause an accidental death.

He thought of cooperating with Xi Mengying that night, pretending to find the dead body under Xiao Keyi's wheel, and digging a pit to help Xiao Keyi destroy the scene of the accident, and he couldn't help but feel murderous in his heart.

That night, what Shen Kai buried was actually a dummy that had been prepared a long time ago. Afterwards, he immediately dug up the dummy, because he had expected that Xiao Keyi might come to confirm it afterwards.

When he noticed that Xiao Keyi was about to go to the burial place again for the second time, Shen Kai secretly buried a prosthetic leg again. Sure enough, Xiao Keyi, who was afraid that he had no ability to distinguish between truth and falsehood, was so frightened that he fell into a coma again.

As a result, Xiao Keyi believed that he had bumped into a ghost, which also provided a basis for Shen Kai to use the 'ghost' to kill Xiao Keyi.

Therefore, Shen Kai, who didn't have time to wait, gave up the original plan, and he had to start in advance. In order to make everyone believe that it was really a ghost who wanted to ask Xiao Keyi for his life, he forged the death threat letter and sent it back to his home, but also to the criminal police brigade.

Of course, the seven-day statement on the letter was just a magic trick by Shen Kai, who asked the police to focus their attention on the seventh day, but he quietly carried out his terrible plan to kill his wife on the fifth day.

What Shen Kai didn't expect was that Xiao Song of the criminal police team secretly believed in ghosts and gods, and actually invited a Taoist priest from other places and a few friends to his home.

When Xi Mengying secretly reported all this to Shen Kai, Shen Kai suddenly felt that it was tricky. But he was not willing to let go, and there was no time to wait.

So, he temporarily revised his plan and decided to go on a business trip in the field by himself, so as not to give everyone a chance to doubt him. Shen Kai locked this final plan of action on his conspirator Xi Mengying.

After Shen Kai's careful consideration, Xi Mengying began to make the final blow to Xiao Keyi after receiving the order.

In order to avoid suspicion, according to Shen Kai's attention, she used the Taoist priest of Xiao Keyi's family and a few of his friends as a cover, and also created alibi evidence for herself.

After careful calculation, Xi Mengying secretly put down a moderate dose of sleeping pills in the meal she cooked. When everyone finished dinner, Xi Mengying estimated that the effect of sleeping pills was about to come up, pretended to be scared, and offered to live in the same room with Zhao Wan'er and Shi Liya.

As she expected, after returning to the room, not long after she pretended to be asleep, Shi Liya and Zhao Wan'er also fell asleep. After deliberately calling a few times to make sure that the two of them were asleep, Xi Mengying quietly got up from the bed and started to act.

She gently closed the door of the room, and came to Xiao Keyi's room barefoot without making a sound.

Xi Mengying gently opened the door of the room with the secret key and came to the sleeping Xiao Keyi.

She used a special psychotropic hallucinogens to let Xiao Keyi take it, and after a while, under the effect of the drug, Xiao Keyi woke up. In fact, Xiao Keyi at this time can't be said to be awake, but she is no longer in a state of falling asleep peacefully, but in a completely unconscious state.

Under the inducement of Xi Mengying, Xiao Keyi, who lost consciousness, followed Xiao Keyi slowly down the stairs like a walking corpse. Of course, Xiao Keyi, who was unconscious, was also barefoot at this time, so he left his bedroom silently and came downstairs.

Xi Mengying induced Xiao Keyi, left the house, and walked towards the carport. She did a lot of calculations, but she was defeated at the end of a thin joint.

That night, Li Bing ate less because his body was not very comfortable, so the impact of the ingredients of sleeping pills on Li Bing was greatly discounted. Therefore, when Zhang Yuanshan and Qian Yiduo fell asleep, although Li Bing was also sleepy-eyed, he still didn't really fall asleep.

When Xi Mengying lured Xiao Keyi, who was in a state of delusion, to leave the house, the sound of the door closing in the hall on the ground floor aroused Li Bing's vigilance. While Li Bing was suspicious, he also got up because he had some urge to urinate, and finally came to the staircase.

Although Xi Mengying and Xiao Keyi have left, the unique smell of Chanel Zero perfume on her body still left a faint aroma at the staircase, which eventually caused Li Bing to smell the perfume on Xi Mengying's body again later, and suddenly remembered the strange smell of the staircase on the night of Xiao Keyi's disappearance, which made him suspicious of Xi Mengying.

Xi Mengying lured Xiao Keyi to the carport step by step, and helped Xiao Keyi to sit in the driver's seat of the white BMW.

Xiao Keyi, whose eyes were glazed, was still unaware of the danger at this time. Xi Mengying quietly took out the sharp knife from the back seat, suddenly grabbed Xiao Keyi's long hair, and the sharp knife in his hand fiercely cut Xiao Keyi's snow-white neck backwards.
