Being able to reach Level 30 meant that he had surpassed 99% of the players in the game and was considered one of the top players.
The difficulty of leveling up was too high.
Usually, most players who reached Level 30 would choose to enter the high-level game world in advance and use the high-level dream crystals that dropped in the high-level game world to exchange for low-level mutation crystals to level up.
This would ensure a certain level of efficiency.
It seemed to be efficient, but doing so would cause the subsequent stages of talent advancement to be partially restricted.
According to the leveling ratio of the dream crystals, the talent advancement would fluctuate, and the highest talent advancement could only reach E-S level.
These were the game settings that the Federation had developed over the years and were classified as top-level secrets.
