Xu Ruosi temporarily changed her statement about the task progress to having passed the level in order to avoid letting Xiao Ling and Yu Guangnan know what they had acquired in the Wax Figure Gallery. She hadn't expected Xiao Ling to have also completed one-sixth of the progress.
Now that things had been made clear, it was natural for Xu Ruosi and her companions to try to gain new progress.
Xu Huo did not acquire new progress; a moment later, Jie Ling and Xu Ruosi nodded at him.
Although Xu Huo did not gain the new one-sixth of the progress, Jie Ling and Xu Ruosi benefited, so they could naturally exchange information.
So Jie Ling informed Xiao Ling and Yu Guangnan about the Wax Figure Gallery, omitting the Strange Tale Room and selectively speaking about what the Wax Figure Gallery ostensibly aimed to express.
