My Fourth-Dimensional Treasure Bag

Ye Ran, an ordinary college graduate, seems ordinary in this era of unemployment after graduation. Until the future, he gave himself Doraemon's fourth-dimensional treasure bag. "Remember to make a copy and send it to your past self in the future to achieve a closed time loop. Other than that, we can play whatever we want and do whatever we want." So... Looking at the other self leaving and the treasure bag in his hand, Ye Ran made a decision: "Anyway, let's create a small universe first - the Creation Combination." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
