The next day, I went to the C-rank dungeon again.
I reached the boss area in less than an hour and used the B-rank skill.
As the giant centipede moved toward me, my plan glowed.
Mana continuously drained from my body creating a massive ball of mana and was fired at the centipede. As the mana touched the centipede, an ear-deafening explosion occurred. The whole area within 30 meters was affected, and a giant crater formed.
The centipede didn't die, but it lay in the center of the crater. Its body had cracks on it, I again cast mana blast, and the crater was doubled. The centipede dissipated. In the center of the pit, a skill book glowed brightly.
I jumped down and took the skill book, and climbed up.
[Stealth: Hide aura, energy, and presence, move undetected.]
Seeing the skill, I didn't wait a second before learning it.

I farmed the C-rank dungeon more than 10 times and moved to the D-rank dungeon.
