Ruan Shishi is the director of the obstetrics and gynecology department of Yan Chai Hospital, and although she has a good income, she cannot afford to buy such a high-end residential duplex building.

I learned from the real estate developer that Ruan Shishi did not make a mortgage loan for this house, and what is even more strange is that this house only has a 30% down payment, and more than one million yuan is still owed to the developer.

Xiao Song wondered why Ruan Shishi was able to get the keys from the developer and move in without a mortgage loan.

Xiao Song realized that there must be something hidden in this, so he summoned the real estate developer. After some interrogation, the real estate developer no longer dared to hide the facts of this life-threatening case, and confessed the truth in a hurry.

It turned out that although this house was purchased in the name of Ruan Shishi, because of the guarantee of Guo Li, the director of Renji Hospital, the real estate developer made an exception to allow Ruan Shishi to take the key to move in, and the balance was temporarily shelved.

Xiao Song was surprised, why did Guo Li help Ruan Shishi vouch? Thinking of the ambiguous relationship between the dean Guo Li and Ruan Shishi, the director of the Department of Obstetrics and Gynecology, who was secretly told to him by the hospital staff, Xiao Song's heart lit up.

In Guo Li's dean's office, Guo Li finally confessed to Xiao Song that he had a lover relationship with Ruan Shishi. Guo Li is already in his fifties, while Ruan Shishi is just in her youth.

After Ruan Shishi entered this famous hospital from the health school and entered the obstetrics and gynecology department as an ordinary nurse, Guo Li couldn't help but think about it because of her natural beauty.

Finally, on a rainy night, after Guo Li called Ruan Shishi into the dean's office, he lured Ruan Shishi to lose her heart with various promises. Since then, the two have established a secret lover relationship, and Guo Li has also fulfilled his promise to Ruan Shishi, using various excuses to create conditions for Ruan Shishi to go out to study, and then abused his power and made Ruan Shishi the director of the obstetrics and gynecology department.

Ruan Shishi is not qualified for this director's position, so the deputy director of the obstetrics and gynecology department is actually in charge, and Ruan Shishi is only nominally holding a vacant salary.

Guo Li admitted that in order to win the heart of the young and beautiful Ruan Shishi, he couldn't withstand Ruan Shishi's soft and hard grinding, and tried his best to take out more than 300,000 yuan to buy this duplex house for Ruan Shishi.

As for why she didn't take out a mortgage loan, it was because Ruan Shishi was worried about the repayment of the house, because it was registered in her name, and it would eventually fall on her head. Therefore, Ruan Shishi firmly did not agree to make a mortgage loan.

Guo Li had no choice but to negotiate with the real estate developer and allow him to pay off more than one million within three years. The real estate developer readily agreed to Guo Li's request because Guo Li was the president of Renji Hospital, and Renji Hospital would soon have a tender for infrastructure projects.

Regarding Ruan Shishi's death, Guo Li was quite sad. He told Xiao Song that due to the recent awkward falling out between Ruan Shishi and him, the two were in a state of cold war and had not been in touch for more than half a month.

From the surveillance video at the entrance of Ruan Shishi's community, Xiao Song found out that Guo Li should not be lying. Because the video of this community has been stored for a long time, as long as a month. Prior to this, Guo Li appeared in and out of the community surveillance video many times, and half a month ago, Guo Li never appeared in the video again.

The criminal police investigating Ruan Shishi's situation reported to Xiao Song that during the investigation of Ruan Shishi's bank account, it was discovered that a few days ago, a huge sum of millions of money had been transferred to Ruan Shishi's account, and it was soon withdrawn.

From the bank's surveillance data, the criminal police confirmed that it was Ruan Shishi herself who took the huge amount.

How could Ruan Shishi's account get millions of dollars? Xiao Song immediately thought of the million-dollar IOU in Qian Gang's bag.

It was a rather strange IOU, which only stated the amount of the loan and the date of repayment, as well as the signature and personal seal of the borrower, Nguyen Thi Shih, but did not mention who had borrowed the money from.

After analysis, Xiao Song and the people of the task force finally deduced the general outline of the case.

For some reason, Ruan Shishi's relationship with her lover Guo Li began to deteriorate. Perhaps Ruan Shishi was anxious to get rid of Guo Li's control and entanglement, and she was anxious to get the actual ownership of the house, so she had to pay the balance of the house to the developer before Ruan Shishi and Guo Li clearly proposed to break up.

Because Ruan Shishi understands that the developer is eyeing the big cake of Renji Hospital's upcoming bidding for infrastructure, so it will agree to Guo Li, who holds the power of the hospital, to guarantee him. If she proposes to break up with Guo Li, then Guo Li will inevitably work with real estate developers to put pressure on her, even if Ruan Shishi wants to make a real estate mortgage loan, I am afraid that it will be burned because of the real estate developer's non-cooperation.

If this is really the case, Ruan Shishi will have to check out, and the money from the check-out will not be handed over to Ruan Shishi, but Guo Li will try his best to get it back.

In this case, Ruan Shishi will gain nothing, which she will never be willing to take. Therefore, Ruan Shishi decided to take advantage of the complete showdown between the two to pool the money to pay off the balance of the property, so as to completely become the property owner of this house.

As long as the property rights of the house are in hand, Ruan Shishi can resell the house, not only to ensure that she gets the down payment of more than 300,000 yuan, but also to make a lot of money because of the rise in housing prices.

Therefore, how to get this million dollars has become the primary goal that Ruan Shishi must solve. Judging from Ruan Shishi's background investigation, it is impossible for her to borrow such a huge amount of money.

An idea came to Xiao Song's mind, Ruan Shishi took a risk, wanting to borrow usury to get the property right of the house first, and then get rid of it as soon as possible.

The millions of dollars in Ruan Shishi's account are the usury that Qian Gang released, which explains why there is a million-dollar IOU signed by Zhang Ruan Shishi in Qian Gang's purse.

Then, Qian Gang's death is very likely to be closely related to Ruan Shishi. Xiao Song speculated that although Ruan Shishi, who was greedy for money, could resell this house to make a profit, she might like this high-end residence very much and was reluctant to sell it.

As a result, Ruan Shishi had a black heart, she decided to get rid of Qian Gang, and then get her own IOU to destroy it quietly, so as to completely own this high-end residence.

Ruan Shishi grasped the situation that Qian Gang liked to go to the Black Rose Bar to have fun, so she quietly entered the bar and monitored Qian Gang's every move in the dark.

When the black light of the bar came, Ruan Shishi took the opportunity to sneak to Qian Gang's booth and secretly put potassium cyanide into Qian Gang's wine glass.

It may be providence, Qian Gang did not drink the glass of wine immediately, which made Ruan Shishi, who was anxious to wait for the opportunity to make a move. After careful calculation, Ruan Shishi had to leave the Black Rose Bar in despair when she saw that the black light moment was coming to an end, and she could no longer steal the huge IOU that Qian Gang had brought with her.

When Ruan Shishi left, Qian Gang, who didn't know that death had come in the dark, drank the glass of highly poisonous wine and died in an instant. And the IOU in his bag that Ruan Shishi could not steal became the key evidence in this case.

What puzzled the task force was, how did Ruan Shishi die? Where is the million-dollar sum that has not had time to be handed over to the real estate developer? For a while, the case became even more confusing.
