As usual, there are a few plot holes/unsolved mysteries.

Although I understand it's hard to keep up with the background of all introduced characters, there are a few characters introduced nicely but later forgotten, like his girlfriend (childhood friend) who takes care of the MC during her study holiday. There are also genius players who are less mentioned near the middle-end of the story, like Alchemy Emperor, etc., just to have them say a few lines to ensure the reader that they're still around but not seen.
The things about Zerg bloodlines. In the last arc of the final battle, the queens somehow get a power boost and magically can use their bloodline to trace the nest, although they're a few generations before. BUT YEAH, just accept the story.

More about the final arc, somehow Diqi (we know that he's a master at copying talent) is irrelevant and can't join the final battle, while magically the resurrected ancient heroes from the Longevity Palace get a big boost and hundreds become more powerful and can barely defeat the MC. It's like forcefully adding plot armor. The leader of the new race is powerful, hundreds of light-years in size, has unimaginable computing brain power but is overwhelmed by the queen Zerg?? Even the Longevity Palace master Shi Zhi (survivor of the dimension race) is weaker than the queen Zerg, although he's the one who defeated all the resurrected ancient heroes??"

It starts to focus more on the individual players and how they interact with the world. I care about the protagonist's interaction with the world he made, as well as the world's own development and its reaction to the protagonist who is their God.

However, when the players start interacting with the world more, it gets harder to find enjoyment to read, especially when they themselves are not suitable to be protagonists. It sets them up to have a great impact on the worlds they come into and make them seem extraordinary, but in reality, (and this is an annoying trend that whenever these players run into trouble, be it the threat of a virtual death, which wouldn't actually kill them IRL, to just being in trouble) they cry and complain and bit*h for help online for the rest of the world to help them, which it does. There is no player who has a stroke of genius or has the strength to surpass these obstacles in their paths. There is not a single compelling player I enjoyed so far once it started to move away from them just developing Spore monsters, because the players are shitty protagonists for their stories. The only time they were enjoyable to read about was when they were just developing species, because it actually felt like they were intellectual while being the comedic breather for the world's development.

In the end, the world the protagonist creates and the beings in those worlds are far more compelling to read about, such as Gilgamesh or Medusa. They have actual stakes to their challenges and adversities, ones I hope they surpass, but I cannot say the same about the players and their misadventures.

The spores will eventually evolve into people and full fledged civilizations, which will master all kinds of magical abilities that the MC will train in and use.

And to reach ever higher peaks he will create different sandboxes to deduce different systems of power, helping the general trend of the civilization at specific history nodes.

On top of all that, to help him make more and more advanced species, he creates a VR game where players from earth can evolve spores for him in a specific sandbox, and eventually send them to his various civilization sandboxes.

The good:

• the obvious one: we can follow the epics of heroes in history and all the hymns of civilization in a short period of time;
• we will also eventually experience all the lore and the geniuses the outside world has to offer;
• the misunderstandings are hilarious, especially the players, as they always find a way to fill the history plot holes the MC inadvertently;
• many things you may think were background plot holes at the start are eventually revealed to be just ignorance on our part (and I say this because from a certain point it's pretty obvious the background has been planned from the start)

The bad is unfortunately also present since the start of the novel:

• the science used is clearly off (even if the rational links that follow are completely sound; I guess it was necessary to make magic in the real world) : it seems to use rational links to justify some magical arts, but it's like the author is someone who only watched short videos on tiktok to know the science (other that the soul ones which we can't say much about), an example is the quantum arts, which are said to be blocked by the density of a neutron star because they work with ultra small particles that can't pass through such densities, but in reality quantic particles aren't really particles anymore, they are also probabilities that can obviously "pass" through a neutron star.
• all science is correct of you don't check it: this is a problem that I found mostly in the early stages, so not really a big problem, an example is how the primordial ocean of the MC first sandbox can't have greater life because plants haven't appeared yet and so the oxigen necessary to have multicellular organisms hasn't appeared yet, but is that so?! Isn't the sandbox still on earth, where there's already a bunch of oxigen?!;
• the MC only aknowledges the blood and tears shed by whoever advances the civilization in the main sandbox, another flaw present predominantly at the start. The players who literally go bald from overworking are exploited by the MC without remorse or praise. They don't even
  know what great things they have already accomplished, maybe only later learning about it if they are clever and lucky enough. They are even abused by the MC for their [B]curiosity[/B] (one of the most humane and things, which is also something the MC lacked in his sandboxes at one time. [B]THIS[/B] is my greatest complaint) (I'm looking at you Akina Speedster bro).

The players sort of stop being useful/unique later on but it makes sense why. I also feel like some othet stuff could have been explored more early on, for example,

1) Di Qi finding more worlds

2) everything with Carolyn (but her part of the story was still good, just would like more focus on her)

3) the heavenly music sect could've been more interesting

4) I would've liked a call back or more information about his life before everything on earth

5) the zergs were explored well but it was very late into the story and it felt a bit rushed

6) Just in general everything after about chapter 1000 felt a bit rush every now and then. I think all the chapters from then on were about 500 words shorter and there were no more double chapters

The main character also felt a bit inconsistent or his motives weren't explained enough. He wasn't given much depth. In general most people's motivations don't really go into much detail.

There's quite a bit of stuff brought up out of nowhere, where it sort of makes sense but some more foreshadowing or ease into the situation would've been better.

Also the fight descriptions later on after the martial arts sort of "take over" is very lackluster and I found myself skimming over it.

Was just a really cool and interesting book. The first 3/5 of the book is very good. The first few civilisations are interesting and the way they connect together is very cool. The way the bloodlines interact is very neat and I wish it was explored more. A few more interesting combinations would've been cool early on. Another good place to show off would've been later on when the something something palace gets introduced and you find out they have a bunch of amazing bloodlines. Like the lie detector/chaos fish. Also the humour with the players is better than okay. Constantly aiming for being bald was the best running gag.

I'm split on all the misunderstandings, it makes the story unique but it feels like the main character doesn't really have a say (even though he usually just goes with the flow).

And for the ending

What I hate about this is the fact that eventhough he knows many people know that the worlds he created are a real world, he still uses Chinese characters and chinese myth in world structures and world building. In one of the arc, he created a bona fide buddhist temple, chinese characters and even a buddhist monks skeleton. Eventhough he knows people are aware these worlds are real, he is indifferent of what they think. People genuinely think that the myths of the past were real (with bvious chinese supremacy stuff) thus creating false history. Because of him people think myths were real thus making them think of false historical evidence and this, as a History student is very infuriating.
