Gao Yuan wanted to wash his hands, but when he turned on the tap, unsurprisingly, no water came out.
He lifted the lid of the toilet tank and thankfully, there was still a bit of water left inside. Since the house was frozen over during winter, the water in the toilet tank was preserved; otherwise, it might have evaporated away.
He put his hands into the tank, washed them with the scant water, and then Gao Yuan moved to the living room to take a peek outside through the peephole.
There were surprisingly no zombies in the hallway, which was a good sign.
Back in the kitchen, looking down, he saw that zombies had piled up two stories high, but they could not see the source that was agitating them — Gao Yuan — so they no longer continued to climb upwards.
Yes, another good sign. It seemed that zombies would move frantically after being stimulated, but without that stimulus and lacking coherent thought, let alone any semblance of logic, their urge to attack quickly diminished.
