Chapter 137: Research Facility

After storing the blood of the mantis into a few vials specifically used to keep medicine, then putting away the carcass in his spatial ring, Xia Fei headed toward the base.

There were slogans on the walls every few steps, such as 'The good of the Alliance above all' and 'Please abide by the base's confidentiality rules'.

The passageway was very long, and the bright lights and dirty air would make anyone sleepy. Xia Fei continued along the passageway while maintaining a pace at 50m/s.

If this was actually a military base, there would probably be strict defensive systems in place. Xia Fei intentionally slowed down and would stop every so often to observe his surroundings.

After ten or so kilometers, he finally reached the end of the tunnel.
