Song Wei finally realized that something was wrong with Xia ruofei.
Because Xia ruofei's body had started to tremble. Even though his expression could not be seen through the gas mask, it was obvious that Xia ruofei was in pain.
"RUO Fei, what's wrong?" Song Wei asked in concern and quickly walked to Xia ruofei's side.
She wanted to reach out to support Xia ruofei, but before she could touch his body, she felt a strong repulsive force. Her entire body was pushed away and she hit the stone wall heavily, groaning in pain.
Xia ruofei could not even speak. Although he was worried about Song Wei's condition, he could not even protect himself and could not escape.
There wasn't much genuine Qi left in his dantian. Xia ruofei felt the meridians in his body ache. It was a sign of overusing his genuine Qi.
However, the heavy stone door was still rising slowly. It seemed that it would not be in place for a while.
Xia ruofei could not help but smile bitterly.
