Nian Shutong was busy dismantling a pig while Fu Yunhe had purchased quite a few single-person showers on Star Network and distributed one to every household.
He also found a secluded spot outside and bought a large public restroom, the kind that turns waste into fertilizer after use.
He simply couldn't let so many people do as they please, and, moreover, this was the most popular type of restroom in interstellar spaces because there was a market for recycling this fertilizer.
Don't think it's an easy issue because many people drink nutrient liquid, so there's very little fecal matter produced, making fertilizer quite difficult to purchase.
Everyone had their own tasks and were absorbed in their work when a loud "boom" caused all of them to look toward the same spot.
Nian Shutong, with a pig's head in hand, didn't release her grip and looked toward the direction of the Rubble.
Because that was where the sound came from.
