[No harem] [Transmigration] [Growth] [Sequences] [Some angst, so proceed with caution] [Not a mindless power fantasy; the early pacing is slow]
This is a world invaded by monsters. When the monsters attack, some of the most outstanding members of human professions awaken powerful Sequence abilities.
With these abilities, humanity manages to establish a handful of federal cities after the monster invasion...
Qiao Shan, an obscure bit-part actor from Earth, transmigrates here by accident. He can watch superhumans use their abilities and awaken their Sequences.
Awaken ten Sequences, and you can unlock an incredibly powerful hidden Sequence!
