Yin saw a prop that was an inconspicuous red gas canister.
It had originally fallen in a corner of the rooftop and looked as if the house's former owner had left it there for outdoor BBQs.
Just like the sofa on the rooftop, initially, Yin had taken it for a mere decoration.
But upon closer inspection, he noticed that the body of the canister was flickering with light, indicating that it could be interacted with.
If a prop could be interacted with, naturally, it could demonstrate its properties.
What are the properties of a gas canister?
It's flammable and explosive!
That is to say.
If he could somehow ignite the gas canister and throw it down,
He might be able to kill all the zombies in the area in an instant.
Not to mention earning a high score, but he could also break out of an encirclement.
After all, being stuck on this rooftop wasn't ideal, and if he spent half an hour here without moving, wouldn't the trip have been in vain?
