Chapter 755

Yu Dazhang had good reason to think this way.

He had continued to follow up on the aftermath of the Tertiary Hospital case.

Although all the perpetrators had been severely punished by law, and the three involved families had been destroyed,

still…

the harvested spinal cord stem cells had never been recovered.

Yes, in truth, the Tertiary Hospital case had not been solved perfectly; strictly speaking, the case was only truly closed once the children’s spinal cords were found.

It was like a theft case where the criminal was caught, but the stolen goods remained missing—clearly an unsatisfactory outcome.

But the problem was, everyone connected to the Tertiary Hospital case had been apprehended; there should have been no other accomplices.

Could it be possible…

that the harvested spinal cord stem cells had already been used in some drug trial, which is why they were never recovered?

In this current case, there are already signs pointing in that direction.

When Yu Dazhang handled the Tertiary Hospital case, he had once heard that genuine spinal cord stem cells were extracted exclusively from children.

If it could be confirmed that these women had been injected with spinal cord stem cells, the source must have been illegal.

Considering this now was too far ahead; Yu Dazhang quickly snapped back to the present.

“What was the purpose behind injecting these women with the substance?”

Yu Dazhang asked cautiously:

“Don’t try to fool me with nonsense like ‘enhancing physical fitness.’ Tell me something that makes logical sense to you.”

He had to say this upfront.

The man sitting across from him was a former gynecology specialist who had held the title of chief physician; if Gu Dingwen played games with medical expertise, Yu Dazhang might not be able to tell.

So he had to crush any hidden agenda before it could take root.

“I asked him, but he clearly told me it was none of my business to know.”

Gu Dingwen’s expression was complicated, his gaze flickering, as if he wanted to speak but held back.

“Say what you want to say,” Yu Dazhang frowned:

“Even if it’s just your guess—speak it. We’ll judge for ourselves.”

He had seen no signs of deception in Gu Dingwen’s expression just now.

Yet an inexplicable intuition was slowly rising within Yu Dazhang.

He felt Gu Dingwen had discovered something—but it remained only a suspicion, which was why he hesitated to speak.

“I do have some personal suspicions.”

Gu Dingwen paused, then said:

“But I cannot guarantee their accuracy, so I fear revealing them might mislead you.”

Seeing Yu Dazhang remain silent, he continued:

“They didn’t just come to inject the substance; at regular intervals, they also came to draw blood from these women.”

His voice grew slightly lower, as if emphasizing the importance of what followed:

“I observed the cycle: it occurred every half to one month—that is, every two to four weeks.”

“And that cycle precisely matches the time it takes for the human body to produce antibodies against a virus.”

Gu Dingwen spoke faster now, eager to get his theory out:

“Therefore, I suspect they are using these women as test subjects. The blood draws are to extract serum, which contains large quantities of specific antibodies—also known as antiserum or immune serum.”

How did it get even more complicated… Yu Dazhang frowned as he listened.

He had already struggled to understand why the other side injected stem cells into these women.

After all, spinal cord stem cells were extremely valuable; some even risked their lives for them.

Yet they mixed the stem cells with drugs, and worse—they used humans as test subjects, then extracted serum.

They were aiming for a one-step solution.

Although Yu Dazhang knew nothing about medicine, he knew drug trials could not be directly administered to humans.
