"Didn't he just say that we should strictly guard the place? In the blink of an eye, he wants us to gather and give a lecture?" one of the guards muttered.
"He's the supervisor, so we only need to obey his orders. If anything happens, he'll have to bear the responsibility. I think this fatty has been underground for too long, and there's something wrong with his brain."
Another guard shook his head and walked towards the door.
Soon, the guards in the various passageways were summoned by the fatty to the entrance of the upper level of the passageways. The fatty had an angry look on his face as he started lecturing the guards.
Su Han looked at the key in his hand and smiled. He quickly opened a door.
