A group of cultivators stared at these four giant pipes and thought to themselves, this kid might have a point!
Someone scoffed, "Can you think of a problem that the people above can't? Inside the pipes, there might be an even more formidable defense barrier!"
This person said, "Yes, exactly. Inside the pipes, there are layers of fire-control systems, waiting to peel a layer off the gold ore when it's transported up. Humans inside would have to endure layers of fire refining, not much less intense than in an alchemy furnace."
The crowd cursed, "Then why are you talking about this?"
"Are you asking us to roast human meat?"
"What do you really mean?"
Someone shouted anxiously.
The cultivator said, "What I mean is, I have a way to ward off fire, I can withstand these flames. To be honest, I've traveled between heaven and earth over a thousand times, never had a problem once."
