Ventilated Valley

Lao Mu is an ordinary and dedicated botanist who raised his daughter alone. His life seems peaceful, but it hides inner loneliness and past trauma - vague childhood memories, early death of parents, broken marriage. The only thing that keeps him going is his smart and sensible daughter, who is also his entire hope in life. One day, Lao Mu and his daughter went to the "Ventilation Valley" Botanical Garden and accidentally discovered a strange-looking plant. Its petals have a metallic sheen, its roots are shaped like a heart, and it emits a foul odor. What's even weirder is that when the daughter peeled off the root, blood-red liquid flowed out, and a rotten sheep's eye was hidden inside. At this moment, the world suddenly lost color, everything around it turned black and white, the tourists disappeared, and only eight of them were trapped. The only thing that retains color is the interior of the ventilation valley. They were forced into the valley, and intermittent radio sounds were heard in their ears, implying a certain rule-"The last person alive can leave."
