The story takes place two years after Ye Xuan became a quasi-sequencer. Relying on the black-framed books left behind by his parents after they disappeared, he continued to search for their whereabouts, but unexpectedly uncovered the secrets hidden behind the sequence world. And the appearance of this black-bordered book is the beginning of all mysteries, the end of all mysteries, or just the process of a mystery. When Ye Xuan enters an ancient door called Custer's Gate, everything will come to light again.
"We are not humans, and we are not non-Sequencers. We can only be Sequencers in this life, now and at the moment of birth. We are just a group of monsters with abilities and wearing human clothes."
The mysterious and illusory truth, the hidden and great existence behind it, the sequence and angels, Cthulhu and gods...
[No heroine] + [Cthulhu] + [Sequence] + [No system]
