A Bad-Hearted Doctor is Unbearably Beautiful - Chapter 11

Does it need to be put in a freezer?

Shen Zhao pondered the reason for the blood sample needing to be frozen for testing.

Generally speaking, how long a blood sample needs to be preserved depends on the type of test being performed.

When an ordinary person goes to the hospital for a complete blood count, the doctor will immediately transfer the blood sample to a 2-8°C refrigerated room. It can be stored there for 24-48 hours, but no longer.

For coagulation tests, the time requirement is even shorter—a test within four hours is best.

However, the blood sample that Old Third Song received was frozen. First, it meant that the person who wanted the test might not have had a suitable testing environment. Second, the test itself was relatively unusual.

This meant that the test was likely related to biochemical and viral pathogens…

“What was the temperature of the freezer?” Shen Zhao asked.

“Oh yeah, that freezer was pretty amazing. I think it was… minus 80°C.”

Lu Xiao glanced at Shen Zhao’s unreadable expression and had no idea what he was thinking.

Lu Xiao: “Okay, can you remember any more clues? Think hard.”

Lu Xiao and Shen Zhao’s group helped Old Third Song walk back to the hospital. Wang Deng was also coordinating a suitable time for Old Third Song to meet his mother.

“I didn’t think there was anything wrong at the time, but now that you ask, I remember some strange things…”

Lu Xiao encouraged Old Third Song with his eyes to continue.

“The person on the phone never told me that the box I was supposed to pick up from the archives was a bomb. When I picked up the box, it felt like there was a rolling ball inside. I felt it roll, and then I heard a strange beeping sound coming from inside.”

“I now suspect that he never intended for me to make it out alive!” The more Old Third Song thought about it, the more he felt a sense of dread. The whole thing was a conspiracy from the very beginning!

After settling Old Third Song, Lu Xiao took the evidence bag and went to find Shen Zhao. Shen Zhao glanced at the needle and casing in Lu Xiao’s hand and slowly looked up.

“What’s this about?”

“Hehe, can you help me test this needle? And also this sleeve—I got a little of that killer’s blood on it.”

Lu Xiao pointed to the blood-stained sleeve of his shirt.

“Are we close?”

“More than close! We went through life and death together!” Lu Xiao said with a cheeky grin.

“Go to your team’s forensics department. I don’t do this kind of thing,” Shen Zhao said, waving his hand impatiently.

Lu Xiao continued to smile, showing no intention of leaving. “I saw that your lab is fully equipped. There’s a lot of equipment there that I’ve never even seen in our forensics doctor’s lab! Don’t be so modest.”

“You’d better really believe that.”

In the lab, the needle was coated with cyanide!

That was close…

Lu Xiao was grateful that he had managed to avoid it. If it had even grazed his skin, he could have died on the spot!

What kind of monumental secret would cause the mastermind to repeatedly hire killers for a cover-up, resorting to such a desperate measure?

The explosion, and the two bodies that mysteriously appeared at the scene, were probably just a diversion.

The mastermind’s true goal was likely those blood samples that were destroyed by the high temperature.

That day… if Old Third Song hadn’t happened to be seen by someone who called the police, he probably would have been quietly silenced after he was done, instead of being used to detonate a bomb with such fanfare.

“This group can get their hands on cyanide, firearms, and ammunition, and they’ve hired killers multiple times. This is probably going to be a tough fight…”

Lu Xiao lay sprawled out next to Shen Zhao’s lab table, waiting for the blood DNA results. He suddenly felt exhausted and gradually fell asleep.

The blood sample was carefully extracted from the clothing fibers by Shen Zhao.

He stood in the lab, his gloved fingers running over the centrifuge next to the lab table. His gaze was focused on the STR detection graph displayed on the computer screen.

The air was still filled with the strong smell of disinfectant. After the blood sample was amplified and analyzed by the centrifuge, the patterns on the screen danced.

As the last data point settled on the screen, his pupils constricted slightly.

This pattern, why does it look so much like…

That’s right. Shen Zhao had seen this pattern countless times during the heartbroken days of four years ago.

Shen Zhao carefully opened the drawer at his feet and took out a green velvet box. He took out the USB drive lying inside and found the DNA test record he had kept from that year…

All the core loci were a perfect match.

He could hardly believe his eyes. The mysterious mastermind he had been searching for for so many years had just shown up.

“What are you doing?”

Shen Zhao was startled by the voice that suddenly came from behind him.

“Look how scared you are. Why are you so sneaky in your own lab?”

Shen Zhao’s throat tightened. His gaze was locked on Lu Xiao’s well-defined face.

“You… did you see what that killer looked like?”

Lu Xiao felt that Shen Zhao had suddenly become a different person. He had been attacked twice before, but Shen Zhao had never shown any fear.

But at this moment, Shen Zhao’s voice was filled with a tension and tremor that he couldn’t hide.

“No, his hat was pulled down, and the collar of his trench coat was up. I couldn’t see his face at all. But I fought him. He’s not the same scar-faced man from the first time. His skills are much better than the scar-faced guy’s.”

“Why are you suddenly so interested in this case? Is the DNA test done?” Lu Xiao rested one hand on the corner of the desk and leaned his head over to look at Shen Zhao’s computer.

“Can you understand this?” Shen Zhao turned his face and saw Lu Xiao’s unshaven face crowded in front of the computer.

“Of course… I can’t!” Lu Xiao said with a righteous tone.

“This set of DNA is an exact match for a blood sample from a stranger that I collected five years ago,” Shen Zhao said, his hand muscles tense and his whole body highly strained.

“What?”

The air seemed to freeze at that moment.

Shen Zhao thought for a moment before continuing. “I don’t know how to explain it, but this person is very important to me.”

Lu Xiao was stunned. “Explain it more clearly!”

Shen Zhao’s eyes were icy. “Five years ago, his blood appeared at the scene of the death of someone very important to me.”

Lu Xiao’s expression sank. “A death scene… Was it murder?”

“I don’t know… The body was cremated very quickly. I couldn’t do anything,” Shen Zhao said, his eyelashes lowered, taking a deep breath.

“That person might be the only one who knows the truth.”

Countless possibilities flashed through their minds, but they were all fragmented pieces that they couldn’t put together.

“I want to participate in the investigation of this case,” Shen Zhao said.

“What? You…”

Lu Xiao was about to say, You’re a soft and pampered guy with no combat skills. How could you go to a crime scene? Then he remembered the two times Shen Zhao threatened people with a scalpel… Maybe it’s not impossible.

“But I have no reason to bring you along,” Lu Xiao still felt it was inappropriate.

Shen Zhao thought for a moment and still didn’t want to give up. “You said you would repay me for saving you. This is how you can repay me.”

Lu Xiao was about to say something else, but Shen Zhao interrupted him directly. “Tell me from the beginning what happened with this case.”

“Wait, did I agree?”

“Don’t talk nonsense.”
