Crank，It's a forgotten industry

[manhua]

Crane is currently the most complex industry. It not only cannot be placed inside the house, but also the methamphetamine vehicle cannot approach the house, and what's even more despicable is that. Its chimney like smoke pillars. It's easy to spot.
Suggestion: Add an industrial fan to blow away its smoke. This can reduce its chances of being discovered and compensate for its disadvantages.

Aww, can someone not do underwater crank runs anymore?
