Time quickly passed as everyone did their respective jobs. By the time the sun had settled down, Keith had managed to dig up simple, but uncommon firepit. There were two holes on the ground.
One small and one large, which both connected to each other under the ground. Keith tossed in some tinder and lit it on fire before he slowly fed more wood to the flames. Once he saw that the fire was stable, he looked at Caleb.
"Come here and shoot out air from this small hole. The air will help fuel the fire better and will reduce the production of smoke." he said. Scientifically, that wasn't the case, but he didn't bother with giving out the proper explanation as he knew that they wouldn't understand.
He watched Caleb do as he said and saw the volume of flames increase. Along with that, he also did not see any more smoke.
