Acid Rain Dissolves Everything It Touches, But One Room Survives

[0:00]When acid rain began to fall from the sky, even hiding under a shelter couldn't prevent their skin from being burned. The sign on a taxi parked on the road also started to slowly melt. Fortunately, just a minute earlier, they had found a bottle made of PMP material and placed it on the ground. The three women endured intense pain under the shelter, waiting for the pedestrian light to turn green. With 45 seconds left on the countdown, Rachel, who could not feel pain, picked up the bottle and went to the phone booth entrance. She poured the acid onto the lock at the door, successfully corroding the rusted chain just before the countdown. And they managed to get inside and answered the phone. Strangely, no one spoke on the other end. With only 20 seconds remaining, Zoe noticed a hint inside the phone booth. It seemed this round was still related to the taxi. However, in their panic, they couldn't calm down enough to search for clues. Moreover, the phone booth could only hold two people. What should they do as the countdown ticked away? Second by second, Rachel noticed an umbrella inside the booth and immediately tossed it to Zoe. At that moment, the countdown ended and a new round of acid rain began. The inside of the booth was relatively safe, but Zoe wasn't so lucky. The umbrella could only provide minimal protection and was quickly melted by the acid in during the searing pain. Zoe unexpectedly discovered a clue. She shouted to her companions inside the booth, telling them to pick up the phone and hang up and answer it again. On the third ring, following her instructions, the taxi doors automatically popped open to escape the acid rain. Zoe rushed into the taxi without hesitation. At that moment, the acid rain stopped. A new countdown began. The two inside the booth quickly ran out, hoping to reach the taxi before time ran out. However, the car doors suddenly shut automatically and could not be opened no matter what. Even worse, the phone booth door also closed on its own, while the countdown continued relentlessly. Zoe tried opening the door on the other side and even attempted to open the trunk. But nothing worked. Brianna and Rachel fell into complete despair. They no longer wanted to search for clues. The two embraced each other, waiting for the acid rain to claim them. After one round of acid rain, they would be reduced to nothing. Zoe anxiously climbed onto the window, but unexpectedly triggered a hidden passage beneath the seat and fell into it. What appeared before her was a children's room. She found a diary and the records inside reminded her of someone.
