After confirming that Xu Woshi was safely hidden behind a concrete pillar, Xiao Yi asked Xu Yingguang, "Uncle Xu, what should I do next?"
Xu Yingguang said, "First, throw the explosive device into the crowd of mutants. You're now on the second floor. If they find and attack you, use the narrow space of the staircase to control the number and distribution of the mutants. Just fire at will at the stairwell entrance."
"I understand." Xiao Yi immediately pulled the pin from a hand grenade in his hand, not needing to aim specifically, and tossed it downstairs—and not just one.
Then, dull, not-so-deafening sounds erupted, followed by the mutants' collapsing roars.
Xiao Yi's ear continually received system notifications about increases in physical fitness, including a 0.005 increase, which must have been caused by the faster types of mutants. It seemed that the increase varied depending on the strength of the mutants.
