So I was wrong in my first review, MC didn't pray every night hoping that he doesn't get killed. He actually went out to a couple of hidden dungeons using his game knowledge to gain skills to protect himself.

Edit: (December 26, 2022)

Although MC goes to hidden dungeons, he always brings someone with him to kill mob monsters as they go there or help him with others things. The hidden dungeon doesn't have any monsters. If there is, then there will only be one or two of them. Furthermore, these hidden dungeons are more like a cave than a dungeon. You will see what I mean when you read the story.

Throughout the story even to up to chapter 162, MC only has one OP skill that does damage, which is Instant Kill. The other skills he obtains help him use this skill more efficiently and increase his survival.

There were times when I was wondering how MC is so lucky to obtain skills in every hidden dungeon he goes to. However, it turned out to be beginner's luck. After like few consecutive failures, he focused on something else.

I really enjoy the school arc that started around chapter 137 because it reminds me of The Novel's Extra. However, Korean readers were complaining about how this was a scam and a rip of their money. : (

Edit: (December 26, 2022) I really regret adding spoilers here if this was going to happen, and this was my first review. I feel like I should add more because of a certain "reason" :) (Me trying my absolute best to follow the Review Guidelines)

Although MC does go to an academy, he is not OP over there. He was sent to the magic department because of his "mission", but he lacks magic (Yes, magic not mana. I would call it mana because he can increase it through practice. However, I'm not an expert on this stuff, so idk). The skills he obtained do not use magic; but in the academy, he is required to use magic. He struggles with magic theory, which most of his classmates can do faster than he can.

P.S. He even failed the magic theory exam, which he studied really hard for.

The reason why I said that the school arc reminded me of The Novel's Extra was that MC is a nobody in the school. The school only allows students to use magic that they teach (Again, MC lacks magic). Thus, although MC is "strong" outside of the academy, he is nobody in the school. However, he still manages to catch the attention of people that are pretty decent in the class (aka strong people in the academy (This is a biased opinion)).

I wasn't a huge fan of the MC attending school, and the arc kept dragging on for so long. The whole arc was somewhat forced, too, in my opinion.

To be fair to the author, it was mentioned that current techniques were better, but the materials ancient mages used were not really available anymore. Which doesn't really explain all the mysteries the MC absorbed, no? They don't require any materials.

The MC was a regressor all along. The original MC didn't have any abilities (he did transmigrate from Earth but had no skills). As a result, he had to struggle. He met Caan, the new hero, who became a precious comrade to him. Unfortunately, she died along with the demon lord. Sometime after that, the original MC managed to attain godhood. With his new powers, he kept turning back time, thousands if not more times, to save Caan. There was a catch, though - he couldn't keep his memories and most of the skills, making it so fate didn't change. That's why he "created" the game of RaSa; it was to indirectly transfer the memories. He also kept some of his skills, like instant death and the soul of the king. And that's where the current MC comes in - he was basically the first iteration, but with the memories of playing RaSa and the two skills.

I find it really frustrating how the current MC was influenced by the original one. Every power of his wasn't really his own. His actions were orchestrated. I feel like the main character that we followed throughout the entire story was fake. Frankly, I'd be really angry if I was in his shoes. Finding out that the skills I got and the actions I took were because someone else manipulated me into doing them and not because of my free will. Frankly, did our MC even have free will in the first place? Had Caan not survived, the original MC would turn back time once again and create a new "character, " starting the cycle all over again and wiping out the whole story.

MC gets hurt because of some fire skill and even though he has regeneration skill he spends about a month in some random church to heal and all this time he is staying there we get some random kids' PoV even though we care nothing about them and they are probably never gonna appear again.

Second note-worthy skil is super regeneration. At the beginning we get to know that it works better than best potion MC can get. It can regenerate whole limbs in less than a day. However for some reason later MC has to lie in bed for weeks because skill can't regenerate some small internal injury even though it healed much worse things earlier on.

Another skill is super sensory. It's a skill that author sometimes just forgets that MC has. It enhances his senses, however as I said it sometimes works and other times doesn't.

For example MC kills one of the lords even though it is forbidden. Now a person with average intelligence would think that if he didn't hesitate once he won't for the second time. However characters here simply don't get that.
