It's not a masterpiece, but it's also not a bad story. It can be a way to fill a couple of hours.
The weakest point of the story is that the MC is too OP, he doesn't have to work for anything - from the very beginning, his Library of Heavens Path is filled with all possible books. It removes the most distinctive part of LHP fanfics - trying to stealthily enter libraries or gaining favors to do the same.
At the same time, considering that the MC has the LHP for over 10 years, he is surprisingly weak. He reached the Demigod rank - max for this small world and for a decade waited for canon, despite being able to read inscriptions, meaning, being capable of breaking into Draconic Realm.
To be fair, though, I must admit that I liked how MC utilized his powers, sometimes in a very creative way. Creating a clone with the disguise of an old master was a very good way to justify him being OP. I also liked that he was able to 'hack' entrances to other Realms. Another curious part was collecting the laws, which improved his inner world, made it more real.
Romance is a very mixed bag for me. A harem (which I don't like), but a small one - only three girls, for me it's a perfect number. He gives obscenely expensive gifts to them without any reason, not expecting anything in return, then is surprised that they fall in love with him. While in the beginning, their interactions were cute, in later chapters the MC becomes completely whipped - after all he's done for them, they dare to ignore him for weeks, because he didn't share every single secret with them, they order him what to do... It isn't fun anymore.
Once again, there is a bright spot - he's in a relationship with Ye Ziyun and Xiao Ning'er - the best waifus from this setting and basically a set. It's very cliche, but I like this one.
Overall, I would recommend first reading other fanfics in the TDG setting, like 'Reborn as a Villain in Tales of Demons and Gods ' or 'Transmigrated in Tales of Demons and Gods' by Wise_Snail. When you finish them, it's not a bad idea to read this fanfic - grammar is not terrible and the length isn't the shortest.
