Yi Jun took out a long prop, and after pressing the buttons on both ends, a transparent film unfurled from the prop, expanding to the size of the entire floor and blocking the windows, isolating inside from outside, even the sound of the wind disappeared.
"This is a Rank-B prop. Besides blocking sound, it also obstructs sight. We can see outside, but they can't see us."
Tong Qi and two other players went forward to check and confirmed that the prop had indeed sealed off this floor, then they felt at ease.
The next issue was about who would fall asleep first.
Tong Qi was the first to offer to help protect everyone's safety, but as for sleeping, he refused.
