Starry Sky Train, I opened a small shop on the train

[Xingqiong Railway Fanfiction] [Daily Taking Care of My Daughter]

Ye Yun traveled to the Xingqiong Railway World and obtained the "Mall of Worlds" system.

Through the system, Ye Yun can sell items from all the heavens and worlds, and can also invite guests from other worlds to the Xingqiong Railway World.

Every time the turnover reaches a certain amount, Ye Yun can get a reward from the system.

The story begins with selling a "coin of destiny" to the Star Core Spirit.
