Li Batian and his group were going through another passage of the Underground City to reach the outside world.
Behind them, over fifty Mechanical Life forms rustily followed. The Mecha, with parts still not reset, had barely come off the assembly line before they had to pick up weapons and head to the front lines.
There were also ancient humans from bygone times who had been modified, their bodies still dusted with mining ash, earth covering their faces.
Everyone's expression was grave, no one backed down, only the heavy sound of steps on the old staircase could be heard.
Soon.
They reached the outside of the city, where small Probe-Mechanical insect-like flyers were waiting.
"Heavenly Eye."
Li Batian said in a deep voice, "What's the situation now?"
The insect flyers responded,
"I am following them."
"You can track me. They have all nearly come out in full force, and everyone in the city has been threatened and controlled, and they have already been taken away."
