After a brief discussion, the group didn't rush toward the third underground level's office area but instead decided to search the first and second floors first, trying to determine the cause of the mutations.
"The power has been off here for quite some time," the Stonemason, leading the team, commented as he looked at the ash accumulated on the metal floor. "The air circulation system has been out of service for ages. If the mutation disaster outside was really caused by the leakage of pathogens from this laboratory, the researchers either evacuated immediately or were trapped here."
Li Ang chuckled. "Considering those two large elevators stuck on the first underground floor due to the emergency power cut, I guess the second possibility is more likely..."
