Collaboration

A few hours later, 

Another sign appeared in the sky, projecting 'Phase 3' to all soldiers in the attacker group.

Kai's group was in front of the other, leading the pack. 

"You have brought your night vision, right?" Yuki put down a box full of night vision while handing one to Shirotsuka Sanae.

"Yes. We bought it after getting our first reward." Kai nodded. "Besides, there should be enough light on the original path. We only need it for speed."

"Yeah. We are attackers, so we emphasize speed. All of the attackers will need one night vision, so they wouldn't be disturbed. However, another reason was the supply. There is no way we can give the whole six thousand a night vision because it won't be only us who need it." Yuki nodded.
