City No. 10.
Underneath Caramel Bar lies the place where the Spy Bureau uses the most primitive methods to store data.
There's always a man named Qing Shen sitting there. He used to be Xiao Shen, but now he's old, and people call him Lao Shen.
He is always prepared to blow up everything here if anyone invades, burying himself along with the invaders in a sea of fire.
Inside, a Door of Shadow opens.
A Shadow walks out, takes off his baseball cap and mask, and relaxes on the sofa opposite Lao Shen, closing his eyes.
In the next instant, his heartbeat stops, and his breathing ceases. Time bypasses him, flowing fiercely around him.
Lao Shen grumbled to himself: "You used to use the Door of Shadow to come in without me saying anything, but can you open the door in front of me next time? I'm old, and my heart isn't too good. If you keep appearing out of nowhere, you'll scare me to death sooner or later."
