Magic Tunnel truly was a top-tier auxiliary skill; although it had not yet advanced, it still managed to enhance the capabilities of someone as powerful as Du You, albeit not significantly.
For this, Du You was very pleased, as it proved that this skill would greatly increase upon advancing.

Shaking his head, Du You dismissed these thoughts and continued to wait for the evolution of the next skill.
Finally, the new skill had evolved; his Moon Shadow Aura had advanced.
