First, the goddess Tang mentioned at the beginning of the story obtained the Devil Fruit from the "One Piece" dungeon world. Maybe I didn't make it clear enough, but this is not her first dungeon world. She has been in the Reincarnation Tower for a long time, which is why she is a genius.
Second, if you fail a dungeon in the safe zone, you can retry until you succeed. Once you clear it, you can't enter it again...
Third, the main function of reincarnation points is to exchange for attributes! In this book's setting, basic attributes are very important. If your strength isn't strong enough, even if you get a Gura-Gura devil Fruit, you won't be able to fully utilize its power.
Everyone is welcome to continue pointing out the book's shortcomings and post them in the review section. The author will read them frequently.
Lastly, since this chapter is out, I'm asking for flowers, reviews, and rewards!
The sixth update is coming soon!
Thank you all for your support!!!
