The Nanomachine Swarm

Hao Ren stood on the metal riverbank as he looked at the endless and viscous, slow-moving liquid in the river. He could not help but associate it with the dangerous lifeblood. All the mercenaries were keeping their distance from the riverbank in fear. Only Hao Ren, Ulyanov and Nolan stood in front. Ulyanov's hoarse voice then reverberated out from his helmet, "The end of the world is just a step away."

"This is the Nanomachine Swarm?" Hao Ren looked down at the viscous liquid in the Gray River. "That's… massive."

"Everyone knows the Gray River is made up of the Nanomachine Swarm." Nolan looked at Hao Ren. "You should have crossed one of the Gray Rivers when you fled the city of the Naturals. Have you not seen it?"

"One of the Gray Rivers?" Hao Ren frowned and steered away from the subject. "No, it was chaotic back then; I was separated from the group. I didn't pay attention to my surroundings. What's your plan to cross this river? By boat?"
