Lu Cang's talent evolution to god-tier is suspiciously only shown to us readers, not the characters. He doesn't reveal its true nature, just says he got Proficiency Mastery. That's smart – he hides the OP part. But I wonder if the author will use this as a secret advantage or if it will be found out later. The tension between hiding power and being discovered could be interesting. I hope he doesn't tell everyone immediately.

Some descriptions are vivid: the stone person's appearance, the lightning bolt striking a tree, the charred ground after training. But others are vague: the dungeon, the celebration feast details, the carriage interior. The balance is off – action scenes get more description than everyday scenes. I'd like more sensory worldbuilding, like what the food tastes like, how the carriage smells, what the sky looks like at dusk beyond "fiery red sun". Small details make worlds feel lived-in.
