The train was equipped with hot water facilities. Jin Long, aware of Su Le's need for milk, had brought along a thermos. He filled it with hot water, making it convenient for Gu Zi to prepare milk for Su Le.
Whenever Gu Zi needed to use the restroom, or when the children needed to go, a guard would accompany them. The towering presence of the guards ensured that those who had purchased standing-room tickets and were sleeping in the aisle would promptly make way, preventing any unpleasant incidents.
As the night fell, the train grew chilly. Gu Zi took out their warm clothes, dressing both herself and the children.
Su Li, tireless in his explorations, had followed Jin Long to the connecting area between the carriages. Gu Zi was at ease, knowing Jin Long was watching over him. The most worry-free of them all was Su Bing, who was either engrossed in a book or busy solving problems, flashlight in hand.
