Who can tell me what happened when Yang Mi played Elaine in The Scream, and what was the ending?

At the beginning of today, I was told that four men, four women and eight people went on a tinkering adventure, and the winner got 1 10,000 yuan. On the boat, a strong wind blew away all the maps, leaving Elaine and Peng Fei ... the first one was attacked by Peng Fei, and then others suspected each other of stealing maps and killing each other. Later, XXX picked up a diary and read it, then died, leaving Elaine a copy. The house met Peng Fei again, and then it was said that everyone was very vain. He wanted money because he didn't want them to get the Jinding or something. I forgot who knew they were killing each other. Someone read the diary and learned about it ... I don't quite understand the final result, that is, Elaine killed Peng Fei, then walked out of the room, then turned around, and then there was the sound of a black screen, followed by the cry of a child ... In other words, I covered my eyes most of the time.
