The qi-trainers of both teams were putting on their armor; the two teams' armor were designed completely differently.
The armor for the thin qi-trainers on the left was smaller and lighter. All the joints were exposed to the air, and the plates were connected by soft tubes, with a lot of the True Qi containers that Li Yao had seen previously on the train added to them.
Attached to everyone's back were pairs of foldable iron wings, which were full of spiritual gas tubes. At the ends of the wings were small holes from which white steam were popping out.
The qi-trainers jumped and warmed up their bodies. As their spiritual gas surged out, their wings opened and closed, and when their wings stretched to the limits, a lot of spiritual gas spurted out and pushed them up more than ten meters into the sky, where they would hover for around five seconds.
