Chapter 58: The Bizarre Zombie Species

```

In the complex dungeons, Su Lun was playing a monster-hunting game with the trial team from "Black Tower Alchemy Academy."

But unknown to them, right above them on the surface streets, a large tank truck disguised as a water delivery vehicle had pulled to a stop in a hidden alleyway.

Several people in black were holding some sort of device, scanning the sewer entrance as if searching for something.

Soon enough, the device lit up with a red glow, and the leader among the people in black spoke.

"Have you confirmed their location?"

"Yes, the target is about two hundred meters below ground, exploring deeper towards the west."

"Release the mutated creature down there."

"Yes, boss."

As they spoke, they opened the valve of the tank truck and inserted the pipe into the sewer entrance on the street. Following a series of gurgling noises in the pipeline, streams of black, oil-like sludge began to slowly pour into the sewerage.

....

The shooting game of the students continued.
