[Bengtie Fanfiction] [Contains many worlds, at least Genshin Impact, Juequ Zero, and Collapse III.] [New book by an old author, feel free to read] Ye Yun traveled through time and became a dying world tree. Fortunately, he obtained a system that allows him to invite people from other worlds to his world to help him fight monsters. Those who are invited will receive a task panel similar to that of an online game. Killing monsters can gain experience and obtain drops. At the same time, Ye Yun can also obtain divine power to restore himself, or exchange for magical functions in the system and props from all the heavens and worlds. Years later, Ye Yun vaguely remembered the two heroes he had summoned at the beginning. A little gray-haired boy and a silly Fu Fu.

[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.
