Can someone explain what guideverse is? I mean how does it work?

Espers are soldiers; Guides are doctors. If u were a high ranking soldier, do you want a student doctor to heal you? No, right? Guideverse is the same. In this manhwa, the esper is really strong so naturally, he is assigned a really good doctor. Espers fight, Guides aid. After every mission, Guides heal Espers so they can fight at their full potential on the next mission.
Although guides can heal espers, their compatibility is a major factor. Espers and Guides should be compatible enough to not hurt one another. Strong soldiers need strong doctors. Weak doctors can't heal badly hurt/ near death soldiers. Strong espers need many amounts of medicine, only strong guides can provide. In Guideverse, that medicine is either physical contact or extreme intimacy. Normal Espers can continue their mission after a short holding hands with a normal guide. Strong espers' need vast amount of time to absorb a normal guide's medicine. See how the compatibility of the two characters affect each other? One of them will die when their compatibility isn't synced.

so how does this placeholder stop bots from automatically update a chapter?

Someone replied to you on the wrong comment I think, here is their answer:
"Pretty sure the bots go look for the next chapter automatically. they will upload i without caring about quality. Probably the first ones they find.
Humans wont be able to upload as fast as bots. If you put a placeholder chapter, the bots would think that chapter s already in mangago so they would look for the one after. Which wouldnt exist for another week. Really only works with series that is up to date with the current releases"
SOOOOOOO GOOD but like all the chapter ends feel like they're cut half way??
right ? like i was reloading ch 1 bc i thought it missed some
i did that too
Let me help you with the chapters a bit
Chapter 1 has 2 parts
The 1st part ends @ "THAT'S HIME!!!NO WAY IT CAN'T BE" in chapter 2
Ithe 2nd part starts after the characters introduction in chapter 2 and ends at the " i didnt say anything weard,right?..." (Before the introduction) In chapter 3
