The group skillfully opened the door behind the central entrance on the first floor of the main building and stepped inside.
A space usually closed off to students began to reveal itself along the corridor.
The sight of the empty banquet hall and the grand hall made the Black Turtle Tower students unconsciously stare in awe.
They couldn’t help but wonder why such a place existed while they had to eat stale bread in the lounge.
Yi Han and Ratford exchanged glances.
"Don’t let your guard down," Yi Han warned.
"Of course," Ratford replied, recalling the thief’s creed: "When returning to a place you’ve already been, you must be several times more cautious."

After Yi Han and Ratford successfully escaped through the underground passage, the warehouse keeper was summoned and scolded by the Headmaster.
But the warehouse keeper remained unfazed.
