How many tasks can present the soil on the shore at a time?

Since the revision of Chen Qing, each chapter has been opened in turn, and it is no longer possible to directly complete the previous resource tasks through the rapid second construction. Therefore, the new version of Chen Qing's chapter task has been specially tested to carry out the new version of the task strategy of land reclamation and the game of breaking the warehouse and pressing the book. There are 13 tasks at a time and 13 tasks every week, which will be refreshed from Monday and need to be completed within Sunday.
