PS: this book should be finished next month, and from today on, xiaogai decided to reward one of the readers who subscribed to the book at the highest level this week. All the grains subscribed to will be returned, and another 2000 grains will be rewarded. This is the promise of xiaogai. The promise of xiaogai is OK, and the subscription can be accumulated, that is, the subscription of one account can be added up with the subscription of another account, Just take a screenshot. The screenshot of Jiaqun shows that after one week, the highest subscriber will be rewarded. There is not much money for the small change, so...
