100% RECOMMEND THE NOVEL AND SIDESTORY

May i ask for spoilers? I feel like there some infos missed in here

can u pls drop the link too

I'm gunna give a spoiler and a missing scenes from the war arc
Deukgo is a very friendly man that like people so the war distressed him a lot

I think lee kiyoung tried to not make him go for the war but deukgo insisted and I think he went for the Frontline

In the middle of the war arc lee kiyoung got so worried about deukgo that he went to the Frontline and cursed Infront of people ToT) cuz he's so worried about him

The war arc is so butchered when it's suppose to be the most hyped arç

SPOILER!!!

And here's the spoiler for the upcoming chapter I hope they don't butcher or remove a lot of scenes

The upcoming arc is basically another Hyunsung getting drunk again cuz he thinks lee kiyoung is going to leave the blue guild and join another then for some reason

The city and guild that lee kiyoung was suppose to leave the blue guild for got destroyed

? And then we're going to have a visit at the demon world with lee kiyoung alone also tentacle warning and we're going to see Belial again !!!

Also if your going to read the novel I recommend reading when the artstyle changes which is the start of Elena's arc

I'll be giving two Links!!! The other one is the official translation while the other is pretty much stolen there used to be an fantranslation for the main story tho which kinda gone

https://www.wuxiaworld.com/novel/regressor-instruction-manual
this is the official translation

And this for quick read
https://novellive.app/book/regressor-instruction-manual/chapter-1

I recommend starting at chapter 206 G.T.O

which is after Lee kiyoung pranked Deukgo in the dungeon along with
Kim yeri, Hayan and Ahn kimo

and the introduction of another group(Han Sora, Yoo ahyoung and Kimchangryeul)

Ps. That's the start of the manhwa adapting differently to the novel

Especially han sora's introduction character

And uhh spoiler for the side story

Rohen arc

Lee kiyoung and some of the group will go to another world which is like a mixture of Orv and danmachi
Oh and also demon king Hyunsung!!!
After this it will be

Altanus arc

where Lee kiyoung will go back in time where Lucifer was still the god of the continent
we will also see Benignore or not benignore as a human
This is also where we will have answers how the crack museum and max exist

1st Timeline

This is the mosttt important and heartbreaking part (srsly I cried multiple times)
In this arc we get to see lee kiyoung going to 1st timeline to search for Kim Hyunsung(he ran away with his therapist )
And also another genderbent version of him that Jincheong created
(yes Jincheong from the war arc)
And his genderbent version her name is Aina Penelotti
1st tl Jincheong fell in love with her

there's even a spin off about them where they are actually married But he summoned an NTR demon to save her so now Aina has to sleep with 3 diff men

Murim arc

Lee kiyoung gave birth to his son and Jincheong is the father
He doesn't know he has a child after only after 8 years passed

Idol arc
Lee kiyoung became an ancient mermaid idol (secret identity)
to save the continent

Alternate earth(?) newest arc
Nothing important happened yet but lee kiyoung is busy acting like a sugar baby to ragebait someone
