Just then, she saw Xu Shu frown and say, "Too slow."
The Chief Maid was startled, "Sir, what did you say?"
"I said, too slow," Xu Shu said expressionlessly.
The Chief Maid looked confused.
Too slow?
What was too slow?
She looked in astonishment at Sotos, who was struggling to pull up the iron door, and at the enormous iron door that was slowly opening inch by inch, bit by bit.
Suddenly, she saw Xu Shu take a slight step back, saw him clench his fists, his shoulders sink slightly, and his legs spread apart a bit, assuming a somewhat strange stance but one that conveyed an immense sense of oppression.
The Chief Maid's heart skipped a beat with foreboding.
Could he be thinking... wait, wait a minute! Wait a minute!
She screamed frantically in her heart, her mouth opening, ready to let this scream out.
But it was too late.
In an instant, Xu Shu lunged forward, his shoulder already slamming into the thick, vast iron door.
Iron Mountain Lean!
