Li Heng scans the canal.

It's like the worst group project... Everyone's broken oxidizers and filters fighting underwater!

Hah! The "filth" was real. Just half tears, half solder burns from my peers!

Too many aquatic engineering majors, zero lab space. Of course they turned the canals into a backyard testing ground!

...And here I thought I was the innovative one.

Well... Since we're here, might as well fish out all the drowned items and host a lost & found.

I'm gonna apologize to the locals and explain the situation...

By the way, I just noticed the control valve is different here. It lets you move the water level up or down. We can reset the water level too.

Thanks for helping. I'll begin the scan now.
