Without thinking twice, Gu Qinghe turned back and flew toward the door of the main hall chamber.
Just like the other doors, a rune array appeared and guarded the place.
"The monster we're about to face might be much stronger than before," Gu Qinghe said.
Ling Jia nodded. She, Yan Ran, and Liu Xi had already prepared themselves for any possibility.
They had promised to help Gu Qinghe fight the monster produced by the defensive mechanism of the main hall chamber.
Gu Qinghe formed hand seals with both hands. A golden rune array appeared behind his back, floated forward, and fully merged with the white rune array.
Ling Jia and the others stayed behind, keeping their distance from Gu Qinghe.
Several rune arrays had successfully merged with the white one.
However, they still needed the formation core, which was usually stored inside a monster's body.
