Because the scene of the crime was particularly chaotic, the police initially determined that it was a robbery. However, with further autopsy, it was found that the deceased's blood contained a certain component of barbiturates, which had sedative and hypnotic effects.

It stands to reason that if it is a burglary, the most it is to tie up someone and kill them, or kill them directly...... It is indeed rare to be stunned first and then killed, so the police suspect that it may be a vendetta.

But Cai Xiaoquan's reputation has always been very good, he is a middle school teacher, he usually has no bad habits, he is very serious and responsible for students and work, it is really hard to imagine that such a good teacher will offend anyone. It wasn't until someone made trouble at Cai Xiaoquan's memorial service that a grievance from ten years ago was opened......

At that time, it was said that although there was no progress in the case, the cause of Cai Xiaoquan's death had been clarified, so at the request of the family, the police agreed to let them understand the body for burial.

But just as the school was holding a memorial service for Cai Xiaoquan, a strange middle-aged man walked in, carrying a black bag in his hand. At first, people thought that this was Cai Xiaoquan's friend, but who knew that the man came to Cai Xiaoquan's portrait and laughed happily, and in the end, he even laughed with tears.

Just when everyone was feeling strange, they saw that the middle-aged man actually took out a firecracker from the black bag and lit it, and the mourning hall was blown up into a miasma for a while! So a few of Cai Xiaoquan's former colleagues went over to reason with the middle-aged man and asked him why he wanted to destroy other people's memorial services? Isn't it too immoral to do that?

Unexpectedly, the middle-aged man sneered and said, "The most immoral person present is this Cai Xiaoquan Teacher Cai, if it weren't for him, how could my daughter die!" ”

Others were stunned when they heard this, and even Cai Xiaoquan's fiancée was slightly surprised, could it be that Cai Xiaoquan had any emotional relationship with the other party's daughter before his death?

But this middle-aged man looks like he is in his early forties, and his daughter is only in her teens at most, how can she have any emotional relationship with Cai Xiaoquan? In the end, someone at the scene called the police, and the middle-aged man was quickly taken away by the police for investigation.

Others may not know who this middle-aged man is, but Cai Xiaoquan's parents know it, and they also know why the middle-aged man kept saying that his son killed his daughter!

After the middle-aged man was taken to the police station, Team Liu, who had been investigating Cai Xiaoquan's case, rushed over, since this man admitted that he had a grudge against Cai Xiaoquan, could it be that he killed Cai Xiaoquan?

As a result, after some interrogation, the other party flatly denied that he killed Cai Xiaoquan, and he said that although he has always had this idea for so many years, he can't choose such an extreme way to take revenge because he still has to take care of his family.

After a police investigation, it was found that the man's name was Wang Chuanwei, 42 years old, and he owned a small local garment factory. As he said, he has a high hall in his family, a wife and children, and he can be regarded as a successful career when he is middle-aged...... It is indeed not worth it for him to lose all his net worth for revenge at this stage.

As for why he said that Cai Xiaoquan killed his daughter, then all this has to start from a look at the past ten years ago...... At that time, his eldest daughter Wang Xiaoqi was less than 8 years old, and the little girl accidentally fainted during a school activity, and was sent to the hospital for examination and found that the child had leukemia.

At that time, Wang Chuanwei's family conditions were not bad, and he could afford the cost of his daughter's treatment, but the problem was that his daughter was best able to have a stem cell transplant in her current situation, so that the cure rate would be very high.

It's a pity that Wang Chuanwei has hepatitis and is not suitable for hematopoietic stem cell donation, and the probability of his wife's incompatibility is very high, so he is not the best candidate. In the end, the doctor's advice was that they wait for a match and have another child at the same time, because there is a high chance of a stem cell transplant match between siblings...... So Wang Chuanwei discussed with his wife and decided to have another child to save his daughter.

Originally, all this was being carried out step by step, but a year later, their son fell to the ground, and unfortunately the match between the younger brother and the older sister did not match. It was at this time that good news came from the hospital, saying that they had found a person who was very compatible with Wang Xiaoqi in the matching library, and now the other party had agreed to donate hematopoietic stem cells to Wang Xiaoqi.

This is a great thing for Wang Chuanwei's family, they feel that they have finally met a good person, so they actively cooperate with the doctor's treatment and are ready to receive stem cell transplantation at any time.

Unexpectedly, on the third day of Wang Xiaoqi's myeloablative chemotherapy, Wang Chuanwei suddenly received a notice from the hospital, saying that the previous donor had repented! This means that even if the chemotherapy is terminated immediately, it is impossible for her daughter's bone marrow to be recovered, and if there is no follow-up life-saving hematopoietic stem cells, Wang Xiaoqi can only lie in the hospital and wait for death.

This pair of Wang Chuanwei is simply a bolt from the blue, if the other party hadn't agreed to donate first, they would definitely not have done that kind of myeloablation chemotherapy, now everything is ready, but the other party regrets not donating?! It's not as simple as cheating people, it's simply killing people!

So Wang Chuanwei immediately found the hospital, hoping to follow the hospital staff to do the other party's work, of course, the hospital also knew the seriousness of the problem, so he found the penitent donor several times, hoping to do his work.

Who knew that every time they went, it was the parents of the repentant donor who came forward to negotiate with the hospital, and they said that their son was young and ignorant, and he had not graduated from college yet, so he dared to donate hematopoietic stem cells without knowing anything? And repeatedly said that they would not let the hospital harass their son again, because they would never agree to their son's stem cell donation.

When the hospital saw that the other party had already said that it was dead, it knew that it must be no fun, so it hurried back to discuss with Wang Chuanwei, if it really can't find a suitable donor, it can only be a dead horse as a live horse doctor, first use the stem cells of the child's mother, and can't watch the child die because of bone marrow failure, right? !

But at the same time, the doctor also told Wang Chuanwei that the possibility of rejection with the stem cells of the child's mother is extremely high, and he must be mentally prepared for this. Of course, Wang Chuanwei couldn't watch his daughter wait for death, so he finally had to agree to this method, which was not a solution.

As a result, in the year after the operation, Wang Xiaoqi had a serious rejection reaction, although the doctors tried their best, but in the end they did not save the little girl's life...... And the boy who originally agreed to donate, but later regretted it because of his parents' interference, was Cai Xiaoquan ten years later.
