Chu Hao knocked on the door, but after waiting two minutes without any response, he knocked again. After knocking for the second time and still not getting any response after a few minutes, he had to take action differently. He knew that the people in the apartments were not asleep and probably thought it was a neighbor causing trouble.
He used his spiritual energy to observe the two floors and found the whole family on the sixteenth floor, probably having some family time since everyone was there.
As they were ignoring the knocks and pretending that they heard nothing, he had to use the ancient methods among cultivators.
He thought this might scare them, but he didn't have a choice. Thus, while sitting together, Grandpa Li heard a voice in his ear, loud and clear.
"Grandpa Li, it's Chu Hao, Grandpa sent me here. Could you please send someone to open the door?" Chu Hao used as low and respectful a voice as possible so as not to scare the old man.
