Li Xiuying looked at her brother and continued, "Even those living far from contaminated areas should not have such normal data. According to our research, rainwater contained not only the zombie virus but also an unknown element never before found on Earth."
"Even without direct contact with the rainwater, as long as people breathed, the unknown element would enter their bodies and cause changes in their DNA sequences."
This time, Li Xiuyu understood his sister's concern. Unless they had used oxygen masks before the first rain, it was impossible to remain unaffected.
Yet from what he observed, Feng He and his group were breathing normally. That made their perfectly normal data deeply unsettling.
After a long silence, Li Xiuyu asked, "So, what do you plan to do?"
"For now, we still need to buy supplies from them. It's better to investigate them secretly, in case we startle the snake."
Nodding at his sister's words, Li Xiuyu stood up and said, "I will take care of this matter."
