Overall, I really like it, so I decided to review it to help the ratings a bit, it deserves more popularity. The story is fun, the magic system is cool and powerful without being absurd; it's a bit vague but still cool. I also enjoy stories that slap Tang San, the micromanaging psychopath, so this is a plus too.
Writing Quality: it's pretty good. It's a translation of course, so you can't expect masterpieces, but it's perfectly understandable with little to no mistakes. My only complaint is that chapters are a bit short, but it's not the translator's fault.
Stability of Updates: it seems like 2 chapters daily, at the time of writing this, which is a good update frequency.
Story Development: It's interesting, follows roughly the main plot points of DD3, but that's to be expected. MC snatches Tang Wulin's opportunities and has some of his own, and I like the direction where the story is going.
Character Design: MC is rather boring at the start, and he feels like an old man. But while he doesn't like to fight, he has plenty of spine and is decisive. The storytime, when he takes advantage of his metaknowledge, is fun whenever it happens, and his teatime habit is fun too. I also really like his relationship with the female lead, they are equal partners and good friends, and while they are a couple now, and they're close, I wish there was some more romance there though. I was hoping for more sweetness, you know? The canon characters are accurate enough, and don't seem 2-dimensional. You end up caring for the protagonist's team. The antagonists also are proper characters, even if there isn't that much tension, since you know MC is going to win somehow. But that's good too.
World Background: It's Douluo Dalu 3 fanfiction, there's not much place for error if you follow the story. Whatever changes from the plot make sense when you count them as butterflies set forth by MC.
