Yao Ying, Yao Ling, and Xiao Fang knew that there was a turmoil outside because the guards were frantically searching for Uncle Qiu. They were probably trying to find guidance regarding Aunt Yue's matter because they had been searching everywhere to no avail.
Yao Ying went out to distract them so that Uncle Qiu would be able to rest peacefully. He was too lazy to do it himself, so he searched Lin Jian and made him to the hard work. Although he knew that Yao Ling needed some spaces with her father, he still didn't want to leave her all alone. Thus, he chose to wait in the garden in front of their courtyard.
Uncle Qiu was left under the care of Yao Ling and Xiao Fang. They could hear that once in a while he was calling Su Wan's name over and over again while he was unconscious. His body was sweating all over, but Yao Ling only dared to wipe his forehead.
