The whole setting of the novel is that the MC’s healing power works to reverse something to it’s previous state. So when MC get’s ahold of the demon kings heart which is pretty much a mega mana crystal that allows the casting of super powerful spells. So by super charging his heal spell he is able to reverse time to 4 years earlier. This is done by his healing spell turning the whole planet and everything on it to it’s previous state 4 years earlier.
So now we know the MC’s power right? To make things take on a previous shape. Wrong!
After this the MC’s power is changed or get’s limitations like how it’s impossible to restore life or life force. Why? Because the author either forgot the setting or decided it’s to OP so it is nerfed/changed through out the story. Frankly I wouldn’t mind that much if the whole story and setting wasn’t based on it.
Also how the F is it that when the MC remembers everything he still decided to act the same at the start which involves him being drugged, abused and r*ped for about 2 months. When he could have much more easily just played a long and done his revenge? Points thats why he wants people to get revenge points so he can take revenge. Fine the MC is insane and s*upid I get it. But how is it that during his first “life” he manages to create 3-4 OP “healing” spells with way different uses and use them to steal exp, skills and boost his stats when he was drugged so badly that the 4 years he couldn’t think about anything but drugs.
He also does this during his two months in his “second” life only this time the reason it took only 2 months to awaken is cause he ate some drugs for a few day’s before going to the castle. Which makes 0 sense since after healing himself his body would revert to a previous state before being druged therefore not getting any of the resistance his body built up.
Also fine you can convince me that the MC can learn to tolerate the pain a single person has gone through when he heals someone, but to not even think or mention that by doing this to the planet and everyone on it he would probably have to be burdened with the pain that everything on the planet has ever felt. And seeing as a single person can almost “kill” him but he adapted to tolerate it, imagine what would happen if that pain is increased by a billion or a trillion. Author seems pretty unaware of this part.
But hey this story is so inconsistant and the MC’s power so badly thought out and always changing. That this is simply a rant at bad writting I guess.
