Zhentian listened quietly, never uttering a word. As for what he was thinking, no one knew.
Just as Su Yi calmed his mind to treat him, the door of the medical hall was suddenly knocked on.
"Is anyone there? The people inside, are you there?" The knocking was very urgent, and so was the voice outside.
Hearing the sound, Su Yi couldn't help but frown slightly, very displeased.
"Don't these people know the rules here? Don't they know to line up?"
Zhentian said softly.
Su Yi's face remained calm, still treating him with a composed and tranquil air.
"Those outside, line up and wait," Su Yi called out loudly to those outside.
"Ah, hurry up and open the door. We have an emergency, a matter of life and death; open the door quickly."
"Divine Doctor, if you can heal our people, I will surely reward you handsomely."
The people outside kept urging.
"I said, line up and wait!" Su Yi said, irked.
