Stellar Train: I Open a Small Shop on the Train

Ye Yun traveled to the Star Railway World and obtained the “Shop of All Worlds” system.

Through this system, Ye Yun can sell items from across different worlds and invite guests from other realms to visit the Star Rail.

His first encounter is with a space traveler named Stelle, and soon... many new experiences begin to unfold.

Each time the shop's turnover reaches a certain amount, Ye Yun receives a reward from the system.
