Chapter 964: Deploying the Trap

Kidney transplantation isn’t the hardest type of surgery, but it’s definitely not simple either.

From the perspective of human physiological structure, any two people of the same gender essentially have no significant physical differences.

However, if you randomly select two people, their blood type protein specificity structures will differ.

Yet, because of the large population base, there will inevitably be some people whose blood types match, and their protein environments inside the body are also quite similar, making them suitable for mutual organ transplantation.

In recent years, with advancements in medical technology, kidney transplantation has become a very mature surgical category.

Thus, when choosing a donor for nephritis, besides blood type matching, there are several specific protein markers to consider, and as long as these markers fall within the specified range, the individual can be deemed suitable for transplantation.

Ma Guochao’s task was simple—after receiving the notes, he would facilitate suitable patients under his care to undergo the relevant tests in this aspect.

After obtaining this clue, Chen Jiang immediately made a call to Lu Chuan.

Upon receiving the call, Lu Chuan was delighted; it was an unexpected surprise.

Since the other side assigned tasks to Ma Guochao at this moment, it meant the police investigation had been kept completely under wraps.

The police now remained in the dark, while the opponent was about to surface, increasing the likelihood of solving the case.

From another angle, this provided Lu Chuan and his team with an excellent lead to expedite the resolution of the case.

Yesterday, Lu Chuan had already decided to trace the lead to unravel the whole case, and it seemed this thread led directly to the mastermind behind it all, landing right in Lu Chuan’s hands.

Given this, Lu Chuan decided to speed up the process.

"Chen Jiang, here’s the plan. Have Ma Guochao return home right now and ensure that his afternoon leave continues. Since it’s already taken, let him take it to the end, but make sure he’s back to normal work tomorrow and conducts a screening of the relevant personnel."

Upon understanding the situation, Lu Chuan immediately made the relevant deployments.

Since the organization behind it had already made a move, Lu Chuan decided to use their tactics against them.

Tonight, the plan was to identify the surgeons on the surgery team so that the situation at Ping’an County People’s Hospital would be largely understood.

This way, after finding the location where the surgeries were conducted and the methods of connection, Ma Guochao would be tasked with finding a fake match candidate.

Lu Chuan already had someone in mind; he would personally go undercover.

The opportunity was extremely rare; Lu Chuan had the chance to personally infiltrate the entire criminal chain.

The opponent hadn’t shown up in the preliminary stages, but would they not appear after the kidney had been harvested?

Chen Jiang understood Lu Chuan’s plan, so he immediately instructed Ma Guochao to return home.

At the same time, the note was also kept by Chen Jiang. He planned to hand it over to Lu Chuan at night since it had appeared in Ma Guochao’s office drawer, which meant someone had placed it there.

Lu Chuan intended to check whether there were any fingerprints on it during the night.

On a separate front was Wang Song’s investigation into the surveillance.

The culprit should have made a move between the end of yesterday’s workday and the start of today’s workday.

This was an excellent point for Wang Song’s work.

Once they found this person, they could potentially pinpoint the identity of the mastermind.

Wang Song had already spent the morning preparing and successfully disguised himself as a worker from a surveillance maintenance company.

The security staff in the hospital’s surveillance room did not give Wang Song and his team much attention. The other party claimed they were there to conduct free equipment checks, so they let them proceed.

President Wang brought two people, and they quickly copied all the relevant video footage back.

However, despite the hospital’s newly installed surveillance equipment over the years, some of the cameras weren’t set up according to high-definition standards.

Additionally, as Ma Guochao’s office was located in the middle of the corridor, only one end of the corridor had surveillance, approximately over 30 meters from his office door.

In the temporary headquarters, Wang Song focused on reviewing last night’s surveillance footage.

"Captain Wang, this... isn’t clear."

Although one could see people in the video, it was indeed not clear.

Even when zooming in, it was impossible to discern faces.

Luckily, the hospital didn’t turn off the lights at night, so the lights in the corridor were on; otherwise, the surveillance would have been practically useless.

"Is it this person?"

Although the faces of people passing through the corridor couldn’t be discerned, it was clear who lingered at or entered Ma Guochao’s office.

Soon, Wang Song discovered something.

"Is it her?"

From the time Ma Guochao left work yesterday to when he started today, the only person who had entered his office was the cleaning staff who came to clean the various consulting rooms this morning.

"Was she the one who placed the item?"

Wang Song nodded. "From the time Ma Guochao left work yesterday until he re-entered his office today, the cleaning staff was the only one who entered his room during that period."

There was no other possibility; it could only have been this person who placed it.

There was practically no chance of someone climbing in from outside to reach Ma Guochao’s office on the 4th floor, and such a target was unlikely anyway, so the note was likely placed by that cleaning staff.

This cleaning staff actually entered every consulting room.

Based on the information from the surveillance, this person was responsible for cleaning on both the 3rd and 4th floors.

Besides the bathrooms on the two floors, she cleaned the interiors of any corridors and offices.

"What now, arrest her?"

Arrest?

Wang Song shook his head.

Since her identity had been confirmed, and she couldn’t run, what use was there in arresting her?

Arresting her now would only alert her partners.

"Check the earlier surveillance and see if this person has appeared before."

"Yes!"

While Wang Song was investigating the surveillance, Lu Chuan’s team had also locked onto the relevant target.

Throughout the day, Lu Chuan sent several people into Ping’an County Hospital’s surgical department to inquire about surgeries.

Now, regarding the situation of the few doctors in the surgical department, almost everything had been gathered.

"Ping’an County Hospital does not have the capability to perform heart-related surgeries."

After all, Ping’an County Hospital is a county-level people’s hospital. While it can handle some minor surgeries, carrying out major surgeries there still poses risks.

Lu Chuan sent several people to consecutively inquire about surgeries and received some feedback.

There are a total of seven doctors in the surgical department; among them, two younger doctors only have the ability to perform minor surgeries like appendectomies in this hospital.

Therefore, the target should be among the remaining five individuals.
