After being able to write 10 of the 24 symbols, he moved on to the remaining ones. For some reason, the difficulty increased exponentially. He found it extremely hard to do every minute action of the engraving. It was as if he was playing the game on easy mode till now, but the difficulty abruptly increased to hard mode.
But that could barely stop his progress or slow him down, he doubled down on his efforts as he continued to engrave more and more symbols. Every new symbol he mastered, the next felt more difficult. The old librarian said that as a Rank 1 acolyte, the highest record of mastering the symbols was 20.
Axel could understand why that was the case. After mastering 20 different symbols, on the 21st one. The difficulty almost reached impossible levels. But with his each achievements, his existence was also improved to a greater extent, which balanced things out, despite the increasing difficulty. As such, in a mere 1 month, he had mastered all 24 symbols.
