Situ Jin's side story: "M-0 Observation Log"

I first met Fan Jinci during an autopsy observation class during my undergraduate graduation internship.

He stood under the operating lights, the scalpel slicing through his chest cavity in an arc that resembled cutting through moonlight. The entire classroom was silent, save for the faint sound of the blade rubbing against cartilage.

While other students gagged at the smell of decay, I noticed that his eyelashes didn't even flutter.

After class, I stopped him and asked, "Why did you choose to make the incision at the third rib?"

He looked at me for three seconds—it was the first time I had been stared at by those grey-blue eyes—and then said, “Because the deceased was 188cm tall, a standard incision would miss the pericardial effusion.”

That night I burned my anatomy notes.

Today, an abnormal fluctuation of 0.3Hz was detected in M-0's brainwaves, corresponding to the moment when Yu Yan was blown away by the blast wave.

Interestingly, when Yu Yan's blood splattered onto his gloves, the fluctuation amplitude increased to 1.2Hz.

Note: The average fluctuation range when an ordinary person witnesses an injury to a significant other is 4.5Hz.

Further observation is needed regarding the physiological costs of suppressing this instinct.

Yan Kang's original data disk was found in the old laboratory.

The neural mapping similarity between M-0 and M-1 is only 73%, but the prefrontal inhibitory function is 400% stronger than that of the latter.

This explains why he was able to withstand the Q-7 toxin—pain perception was forcibly converted into logical operations.

A torn piece of sticky note: If only I had met him first…

Thirty-seven hours after he was shot and fell into a coma, I finally did something that violated research ethics—I synchronized my brainwaves with the monitor.

When the instrument showed a sudden increase in alpha wave activity, I heard him call out a name while he was unconscious.

It's not Yan Kang.

yes……

Jiang Zhaoyan is right; we are all observing the moon in different ways.

He built an observatory, Yu Yan dreamed of plucking the moon from the sky, and I—

All I need to do is make sure the clouds are thin enough tonight so that the moonlight can fall completely into my microscope.

Lock it in safe number 3 and set the key to M-0's birthday.
