Yeah, still have the same problem. The grinding became less as the characters got stronger but the constant crafting of weapons every 5-7 chapters is still there and is kinda boring.

It isn't exactly a harem as, while some girls showed romantic interest in him, he either didn't know, or even if he knew, he still made sure to show them that he only loves a single girl. Till the last few chapters, that is. He accepted them all in the last few chapters. Not all, just a few ones he was very close with.

• • - And perhaps due to that, on Yu IlHan's retina, after he woke up in the morning after a good sleep, a line came up quietly.
    [You have awakened Resting Lv Max. Efficiency of all acts of rest increases dramatically. If you have the skill evolution materials, you may evolve the skill to the next stage.]

    [Resting skill? Just when did you learn a skill with a difficulty of acquiring rank of SSS!?]

    "SSS rank? This thing is harder to learn than R*s*ng*n!?"

• • "I'm alright so say it easily as you always did."
    [The skill becomes so OP that it makes a plastic surgery ad of 'Before & After' laughable.]

    "Good, much better."

• • - [You don't seem to be that surprised?]
    "Oh, I'm sorry. I'm weak in pretending to be surprised. Should I do so now?"

    [f*ck off!]

• • - Yu IlHan's vision became black.
    "That's strange, I opened my eyes, but I'm not in the P*k*m*n center!"

• • - "Although I have officially neven passed through the gate, if it's now, I'm full of baseless confidence that I can pass through the gate without other people knowing!"
    [Bullsh*t baseless! That's called illegal trespassing!]

• • "I knew I am not so bad."
    [Of course, only if you hide your face that is.]

• • "Why do strange things happen wherever I go? Was I K*nd*ch* H*j*m* in my past life?" (lmfao he's talking about Kindaichi Hajime)

• • [That's because beauties are sleepyheads!]
    [But not all sleepyheads become beauties. If it's as you say, Sn*rl*x would have become a heroine long time ago.]
  • "Now I just have to do the same thing and keep digging until I reach the heart, right? It's alright. I played a lot of Minecraft back in the days."
  • On the other hand, the titan started moving slowly after roaring once more. The group with the imperial princess, who had formed a defensive line and started chanting offensive magic, seemed to be scared stiff by the moving titan that exceeded the realm of their imaginations.
    "On that day, mankind received a grim reminder.......... Uuuuugh! Mommy!"
  • "Damned things. They're coming at me like middle schoolers to the cafeteria at lunch."
    [So IlHan also had such a cute time?]

    "Of course, I was reading a book in the classroom while no one was there. Thinking about how a girl tried to sit on top of me thinking that I really wasn't there, is quite a good memory if I think about it now."

  • "He was a truly good extra until the very end. He didn't throw any baits and left like a douchebag."
    [To think he was insulted like that even after death, such a pitiful extra.]

The other thing I didn't like after finishing it was how the author didn't address Mc's mental condition due to those thousand years at all. There were few moments where people he was close with and who knew that he was trapped for thousand years in Earth addressed that how the MC keep cracking jokes on the outside to maintain his mental state etc, etc but they knew he wasn't in a good state, mentally. I was hoping for something related to this in the future chapters, where his mental state gets degraded, or where he shows some negative signs after seeing something and people catch on to it, but that didn't happen. The only effect of the thousand years time-stop I can see is that the MC got a power boost and got closer to Liera, who later became his main wife.

The MC just shitted on God so bad in the last lmfao

Supposedly the 'monsters' are immune to the original rules of the world (physics) in that they are supposed to be immune to human innovation and science, being the fantasy creatures that they are. They even explicitly state that not even nuclear weapons would be good enough to stop them. However, the MC builds a pile-bunker (well within the reaches of human understanding/knowledge/physics might I add, nothing magical about a damn pile bunker) and uses it to easily squash and one-shot high-leveled mobs

MC spends only 250 years to read every single book in the world. On top of this he traveled to every country in the world and just about learned every single language. You have to consider that, even if this was possible, you'd have to be some kind of freakishly fast speed runner with a perfect memory and a incredibly powerful comprehension (i.e. You basically have to be a genius). Despite this though, the MC still acts somewhat braindead at times and you often question how smart he really is.

What's also hilarious is that he spends an additional 50-100 years learning how to be a blacksmith, because apparently forging swords trumps nukes. And apparently, learning how to become a master blacksmith takes a quarter of the time it would take to learn all the languages, read the books of, and visit the countries of the world.

There is no explanation, or hints about why the MC was left behind and thus unable to learn how to control mana. There is no explanation why the angel that visited him could not teach him mana control in his own world, or why building up his body when even nuclear weapons supposedly won't work against these mobs, what is a karate chop or a round house going to help? Basically the MC memed his way into becoming a proverbial Chuck Norris and now somehow he can compete with people that have powers that allow them to surpass nuclear weapons (checkmate, Gandhi).
