The three of them passed through the hallway and entered Zone B. Since Zone B had been deserted for a long time, the zombies there were dormant.
As long as Angelica and her teammates didn't make a sound to wake up the zombies, they could sneak in safely.
Therefore, the most important requirement of the mission was to maintain absolute silence!
However, at the beginning of the operation, the male professor accidentally kicked an unopened can while passing through the cafeteria.
The unopened can kept rolling, hitting obstacles on the ground and making sounds.

Meanwhile, Angelica and her teammates stood in place, not daring to move. They were extremely nervous and observed whether the zombies were rushing over.
Fortunately, their location was far away from the laboratory, so that the zombies couldn't hear anything.
