In Master's mind, the gourds were chattering loudly and non-stop. Instead of stopping them, he used the rules of the mini-world to carefully observe their changes from the side.
Mr. Sun discovered that their previous memories were not erased, but instead, they seemed to be influenced by some sort of power, similar to a seal. As they grew stronger, the seal gradually unlocked. Mr. Sun even guessed that after they became more powerful, they would find the seal within themselves and break it.
The gourds obviously didn't realize this yet.
As they were talking, suddenly, Gourd Old Fourth and Fifth's atmosphere became tense. They each showed their true forms in the mini-world and clashed with each other loudly.
"I deeply despise this fellow in my memories!" Both gourds said together, "How did I end up becoming brothers with him?"
The other gourds also manifested themselves and shouted while shaking, "I remember too! I remember! They were mortal enemies."
