「The next day.」
Lin Feng set his alarm, got up to make breakfast, then knocked on the door to call the quadruplets. The quadruplets yawned as they came to the table, but they were wide awake after eating.
Lin Feng told them to dress warmly. "It's cold out this early, so wear extra layers. Put your work clothes on over everything, and don't forget your hats. The tools you brought back are by the door. Let me know if you'll be back for lunch."
Watching his children's retreating figures, Lin Feng's eyes were full of concern.
Back in the bedroom, Zhang Yuxi groggily asked, "Have the kids left?"
Lin Feng lay back down. "They've left. The place isn't far from here, just a quick ten-minute walk."
Zhang Yuxi glanced at the still-dark sky and snuggled back into Lin Feng's arms, falling asleep.
「Meanwhile,」
As soon as the quadruplets stepped outside, the cold wind made them shiver.
Their first stop was the subway station. The people already working there greeted them.
