On the ceiling, a square-sized ventilation duct caught Luo Yi's attention. He slowly stood up, gestured a few times, and then said with a hint of joy to the two warriors beside him, "I've got an idea!"
After briefly explaining his plan to his comrades, the other two understood and immediately sprang into action.
Because the ceiling was about three meters high, the warriors had to form a human wall to allow Luo Yi to reach the top.
Fortunately, Luo Yi wasn't short, otherwise getting into the ventilation duct wouldn't have been an easy task.
With the combined efforts of the three, Luo Yi quickly touched the louvered opening of the ventilation duct with the help of his comrades.
To avoid alerting anyone outside to the noise inside the room, he carefully removed the obstruction from the duct opening, tilted it aside, and gently handed it to his comrade.
After resolving the entrance issue, Luo Yi stood up again, placing his palms steadily on the edge of the duct opening.
