Who on earth is Feng Jiu?

The moment the door opened, the headmaster, the deputy headmaster, and Teacher Lü quickly turned around to take a look. They saw Feng Jiu, wearing an azure robe, and Guan Xilin coming out together. They both had an indifferent look, nothing special. But after seeing the two doctors, their hearts sank. 

Could it be that it's impossible to save him? After eight hours passed, based on what Mo Chen had said before, Teacher Lu should have died four hours earlier.

"Headmaster, deputy headmaster, he's inside. I have given instructions to the two doctors. You can manage the rest! I don't think there's anything else I can do, so I'll take my leave." Feng Jiu and Guan Xilin walked out and left.

When those three heard Feng Jiu's words, their hearts palpitated. He's indeed dead? Were they supposed to deal with the funeral arrangements?

They rushed inside.
