Criminal Investigation: Don't Trust Yourself

An eleventh severed finger emerged from the eleventh black plastic bag. Forensic pathologist Shen Yuan heard the plea for help of her undercover boyfriend Lin Xiao, supposedly dead, inside a ring. A distinctive "Double Y" knife mark led to a poppy farm cultivating living people, the painless-obedience drug "Angel Bone," and the cloud-based drug lord Mr. Mei.

From the docks to five cities around the world, from the bone-marrow darknet to Formula Zero, they severed fingers, severed blood ties, severed memories, yet they could never sever the cycle of poison.

Only when Shen Yuan stopped her heart to blow up the world did she discover:

The real poison is the void in human nature.

The real severed finger is the story's mystery, doomed never to heal.
