"Master, I think I've made it through."
However, the old man stood there without answering Su Mo.
"Master!"
Su Mo couldn't help but softly call out again.
Poof~
At this moment, the old man's face flushed crimson, and then he opened his mouth, spitting out a mouthful of black blood.
The once energetic face, as if the last spark of life had vanished, became extremely aged and twisted, his whole body wavering unsteadily.
Su Mo's heart suddenly trembled, and he hurriedly reached out to support the old man.
"Master, what's wrong?"
"I'm fine, don't mind me, go open the door."
The old man said weakly.
"Okay."
Su Mo quickly responded, assisting the old man as they walked towards the special metal wall.
When the two reached the metal wall, the old man said to Su Mo.
"Don't support me, just place your hands on it!"
"Okay!"
Su Mo immediately followed the old man's instructions, placing his hands on the metal wall.
