I would categorize this novel as "junk food" within the tower genre, lacking coherence and internal logic. If you're looking for an OP protagonist battling powerful monsters in a tower-climbing setting with stats and skills, it might be entertaining, despite its flaws.
The inconsistency starts with the tower entry, which appears random at first, yet most characters are affiliated with guilds once inside. There should be a logical explanation for this apparent preparation, but it's never clarified. It's not a deal-breaker, but it's an oddity.
Another example is the protagonist's discovery of hidden secrets, which surpass what larger guilds or governments know. While plausible, it's implausible that nobody has explored these secrets before, especially for training or resource gathering. It's hard to swallow that no one has tried to exploit these opportunities.
The MC's luck is another issue. Initially, he experiences extraordinary luck leading to skills and opportunities. However, the tower suddenly grants him unlimited lives without a clear reason, apart from having two high-ranking skills. This reward doesn't make sense, especially when most characters have limited lives compared to his infinite ones, which don't seem to significantly impact the plot.
In summary, while the novel offers an entertaining premise, its lack of internal consistency and illogical elements detract from the overall experience. It might still be enjoyable for fans of the genre who can overlook these issues.
