Not only that, this football-like fire extinguisher can fly like a drone and search for heat sources on its own.

It only took less than half a minute for the flames to be extinguished in the area visible to the naked eye, and then it flew away on its own and continued moving towards the interior.

Fang Linyan maintained the mentality of asking if you don't understand:

"Hey, man, this thing is really advanced!"

Jie Ha said proudly:

"Yes, this is the Gufeng fire extinguishing ball we purchased just six months ago! It sprays specially processed hexafluoropropane gas, which can quickly isolate the source of fire."

Speaking of this, he said curiously:

"By the way, batteries, haven't you ever done this kind of work? So how did you find that damn fault just now?"

Fang Linyan raised his eyebrows, knowing that the other party would definitely ask such a question, so he pointed at the giant watertight door and said:

"Is that what you're talking about?"

Jieha said with joy:

"Of course! Your skills are really amazing. To be honest, I can't do it."

"And did you know? During the disassembly process, your movements really have an indescribable taste, great!"
