According to Gu Youyou's description of the Secret Realm environment, could it be the Bloody Battlefield?
However, Gu Youyou mentioned she was invited by her own kind to enter the Secret Realm, which suggests there must be something that allows access to the Secret Realm Gu Youyou described.
Could it be this Pass Order?
Monsters dropping a Pass Order as loot, Zhang Chi didn't even know how to mock this situation.
Let's just assume that this Secret Realm was intentionally arranged as some sort of assessment!
Zhang Chi felt that the Green Vine wasn't very powerful; its main weakness was its low intelligence. He wondered if the people who had disappeared were also dealing with the same monster. They should be able to win as well!
Zhang Chi didn't know that although he was the weakest in strength, he was the first to kill the Green Vine.
