You must stop writing incomplete chapters, if you are sleepy, just sleep and finish writing the next day, but do not upload incomplete chapters ... I also would have preferred you hadn't added any "characters" from their past life, you already have a lot of material to work with, adding OCs would just overload it. I don't like the system either, you would have given me birth as Ackerman and voila, the plot would run its course without any kind of omnipotent system. (Google translate)
I will drop this Novel here, good luck though Author. My Reasoning for dropping is because of two things mainly... 1) I really don't like the OC with their Drama BS 2) How you repeatedly make the MC look either completely stupid or seemingly nerf him (Bans Immortality and in this Chapter the "Stealthy Titan" who is somehow big enough to directly bite the MCs 'Real Body' in half inside the Titans Neck)
