The difference between the new edition of Douro Mainland and the collector's edition is that if it refers to cards, the cover of the collector's edition is hard paper, and the paper quality is better.

If it refers to the Douluo mainland physical book, the difference is not very big. The collection was changed into a hardcover book cover, and then the cover was painted more beautifully, and then there were every book. I added one more.

There are 13 or 14 stories in the collection, and three other stories have been written. "Douluo Continent 7 (Hardcover Collector's Edition)" mainly tells that in order to revive Xiaowu, Tang San struggled to find herbs. With his efforts, Xiaowu saved her life with the help of "lovesick and heartbroken", but she is still in a coma and needs to wake up slowly. Tang San made a decision that surprised everyone-he decided to get engaged to Xiao Wu.
