It's not continuation of another Manhua, it's called Guideverse. In guideverse, Espers are superpowered individuals who fight monsters but risk going berserk, while Guides are special people who stabilize an Esper's energy through physical contact or intimacy. Overusing powers makes Espers lose control, requiring specialized stabilization, known as "guiding," to prevent mental breakage or death. Guides possess the ability to soothe or "guide" an Esper back to normalcy. This is often ranked by compatibility, with S-class pairs being the strongest.
I just copied and pasted this from meta, you can research more if you want to know more
Well a guideverse is a special world, very similar to many things.
If you are familiar with omegaverse I can give some similarities to help understand although it's very different because it's also like an action, supernatural fantasy or game like manga too
In an omegaverse there's something known as Alpha's. There's dominant, regular and recessive alpha's not all are equal.
Alpha's are known to be successful and have powerful genes. The downside they have strong pheromones and go through a rut (Sexual thirst or frustration, high libido, intense stamina,high thirst for intimacy) that can last for several days during that time they can be very cranky, aggressive and violent. Suppressants for rut exists but it's not always effective and has serious side effects but sex with omega can alleviate their symptoms, especially if their pheromones are compatible.
Espers are similar to alpha's.
They come in different levels and ranks. The highest level esper varies in guideverse stories. I often see level S or SS as the strongest.
The Lowest levels I've seen for guide/esper is D or F depending on story, they're usually not treated or cared for very well
Instead of pheromones Espers have energy waves that can surge out of control and create massive destruction that's called a Rampage. Which can destroy buildings, blocks, cities and possibly a whole planet.
Espers have supernatural abilities that are used to fight monsters who emerge for dimensional rifts, destroy dungeons filled with monster and are supposed to protect regular
citizens who do not have special abilities.
Guides are like omegas. In omegaverse, omega's pheromones can calm and soothe and alpha if they're compatible.
Guides have different wavelength that can calm and heal an espers body. Through physical contact. Powerful or unique guides can use contactless guiding, meaning they can calm and heal an esper with their energy wave alone just being near them without touch.
Depending on a guide and espers level and compatibility how effective their guiding is, the deeper the wound the more physical contact and energy is usually needed to heal, sex is usually needed to heal someone critical, otherwise hugs, holding hands, kissing, groping or oral is sufficient for guiding.
Espers and guides often work in units/teams and have to fight monsters in real world or in rifts to dungeons. Guide are usually on standby while espers go on missions.
Sometimes guides are strong, know how fo fight like espers, some know how to wield their energy like a weapon, some know how to borrow strength from their espers if they are pair/bonded or have a unique constitution.
Most guideverse the moment you manifest as a guide or esper you're automatically become apart of an association/government because you're needed to ensure humanities existence.
In return all damage you may create is covered, your home and living fees are arranged, if you have family or loved one they're cared for the higher your level and contribution the better off you are
Some dungeon have treasure that help advance technology depending on the story.
Depending on the story there's sometimes wars against esper terrorist who don't want to comply to rules and things of that nature.
Espers are sometimes bullies they abuse those weaker then them but coward to those stronger and of higher ranks. Some are thugs, rapist and complete trash
Bonded esper and guide energies and in sync they can sense each other, sometimes they have an engraving depending on story
Omegaverse also have their own version of bonded pair which comes in various forms but essentially they can sense and calm each other too.
I don't know if this explanation gave any clarity on what a guideverse is but I hope it helped

Can someone explain what does esper and guide mean ? I don't know if i'm slow but It my first time reading something like this... is this like a continuation of another manhua ? I m so confused on what's going on but this looks too good to just skip.
