Well, I can say the following about this fanfic:
1) This fanfic fully reveals all the characters, their shortcomings and incentives for improving/eliminating these shortcomings.
2) The volume and quality of the fanfic is excellent, I would compare it equally in my list of serious novels/fanfics that I like, such as "Tree of Aeons" and "Eternal Samsara".
3) It is worth noting that although the speed of the story is a little slow due to the number of words and the sharpening of attention to some incidents, but thanks to this, the author reveals the depth of the characters and the world background very well.
4) Honestly, the author analyzed and explained the various elements of powers/bloodlines, etc. well, so that even an ignorant person could understand how the power system works and how to become stronger. The main thing is that there is no instant strengthening of the heroes right from the beginning of the fanfic or an invitation of new chat members.
5) Author, I hope you can work out a good system for inviting chat participants (and of course, controlling their number) and if there will be any missions from the system itself (I generally hope that the participants themselves will become catalysts for various missions like saving Alabama, because of which the system can reward them, otherwise missions from the system itself like saving and inviting a participant from a new world will look so-so.)
6) It would be cool if there was some kind of item for jumping into a random world, in which chat participants do not necessarily have to add a person from this world, but use the world as a resource.
7) It is good that the fanfic maintains a balance of attention between communication in the chat and the outside world.
8) Everyday life in the fanfic is very good, now I will eagerly await the unfolding of future conflicts, battles (possibly wars) and logical overcoming of one's limits.
9) Keep it up author, the main thing is not to stand out and consistently post chapters (^.^)
