Early in the morning, Ren Xiaosu reexamined his mind palace to discover the quest to help someone in dire straits to escape had been completed.
"Quest complete. Awarded 1.0 Strength."
This was a long-awaited fitness improvement reward. During the night battle with Midnight, Ren Xiaosu had realized the importance of having a good fitness.
During a battle, the most important and essential traits were strength and speed. When he had overwhelming strength and speed, his opponent might not even get a chance to use their superpower.
Furthermore, the fitness of the shadow clone was double that of Ren Xiaosu's own physical fitness. This meant it was a multiplier of his strength and speed. The greater Ren Xiaosu's fitness was, the stronger and faster the shadow clone would be! When Ren Xiaosu's strength increased by one, the shadow clone's strength would increase by two.
