It's hard to describe, but it's full of desperation.
The Serpent People could certainly detect the Expeditionary Army on the ground; they were not simply ignoring them. They were just waiting for the right place, the right moment, and then they would launch an attack.
Some memories simply could not be forgotten. Thinking about the tragic fall of Shimen Shelter No.2, thinking about Wang Hu, a regimental commander, who could only lead zombies away with a gun, Gao Yuan couldn't help but feel panicked.
"The Serpent People could have easily wiped out our entire Expeditionary Army on the road, but they didn't. They waited until we arrived at the Guisui Shelter and then suddenly attacked. Why, why is that!"
Xinghe thought for a moment and said, "It's simple. The Serpent People are conducting experiments. They are searching for effective methods to eliminate humanity, methods that are swift and effective."
"Experiments?"
