Spoiler Alert
The Walls Are Closing In
So, the guys decide to head back the way they came. This turns out to be a terrible plan. Pang Zi is the first to notice something is wrong. The walls on either side of them are moving. Xiao Ge looks up and confirms it. They are slowly being pushed together.
You can guess what happens next. Total panic. They can't go forward. They can't go back. Xiao Ge tells them their only option is to climb.
A Tight Squeeze
Now, Wu Xie and Xiao Ge are lean guys. Climbing isn't a huge deal for them. Pang Zi, though, has a tougher time. He's fighting his own weight and gravity, and he's moving slow. The walls are getting dangerously close.
Xiao Ge reaches down to give him a hand. But Pang Zi slips. He slides down the wall and gets wedged in the closing gap. It looks bad. Xiao Ge acts fast. He throws a rope down to Wu Xie, who doesn't even hesitate. Wu Xie jumps down, ties the rope around Pang Zi, and then loops it around himself. Xiao Ge has to pull up two people. He somehow manages it, hauling them both over the edge just in time.
A Message from the Past
They're finally safe, stuck on top of the wall. Up there, they find something chilling. Someone wrote a message in blood. The writer claims Wu Xie's Third Uncle did something shameful. He forced this person into a desperate situation with no way out.
This triggers a memory for Wu Xie. He remembers hearing whispers when he was a kid. The Xie family hated his family, the Wu family. They always said the Wu family wronged them first. This must be the reason why.
The Truth About Third Uncle
Xiao Ge finally connects the dots for everyone. He lays out a pretty convincing theory. He believes Xie Lianhuan was with Third Uncle on the shore that night. Third Uncle found what he was looking for, some kind of incredible treasure. He wanted to keep it all for himself.
So, he tried to lock Xie Lianhuan in this tomb forever. The plan failed. Xie Lianhuan managed to climb the wall, just like they did. He thought he was trapped, but then he found a loose brick in the ceiling. He dug a hole and escaped. But it didn't matter. Xiao Ge says Third Uncle must have killed him after he got out. The body everyone found the next morning was Xie Lianhuan's. Third Uncle was right there, saw the whole commotion, and just played dumb.
A'Ning's Discovery
While all this is happening, A'Ning is off on her own, looking for an exit. She stumbles upon a dead body. She searches it and finds a micro camera. She takes the memory card and plugs it into her phone.
The footage is horrifying. It shows exactly how the person died. A Sea Monkey attacks him. We see Third Uncle was there. He tried his best to save the guy. But the Sea Monkey was too fast and killed his companion. After seeing the brutal wounds on the body, Wu Xie is shaken. He stops doubting himself and starts muttering that the real crisis is about to begin.
