Without time to think too much, Zhuge Jun headed straight to the boss room and then successfully took down the boss.
He had no choice, the difficulty was just too low. As a player on his second playthrough who had already mastered most bosses' GP timing, taking on a boss at the lowest difficulty was a walk in the park for Zhuge Jun.
After the fight, Zhuge Jun checked the changes in the Dynamic Difficulty value.
Although he still carelessly took two or three hits, the difficulty was now 1 (1200 points), which was still considered "lowest difficulty"!
This was important as it determined the margin of error allowed during the boss fight.
If being hit once would knock him out of difficulty 1, then the error margin would be too low and the bug would be hard to exploit.
