บท 300: Shadow Style Proficiency:Expert!

Zero spent the next few days honing his skills and mastering his Shadow Style. He spent hours each day practicing and experimenting, pushing himself to his limits and beyond.

As he fought with the same monster every day, Zero was easily able to predict their attacks and counter them.

As he gained experience and grew more powerful, Zero began to notice that the monsters on Floor 15 were no longer a match for him.

Zero's strength had grown to the point where he was able to take on multiple monsters at once and emerge victorious with ease.

Zero had even defeated the Floor-15 boss monster which was War Troll. These trolls are larger and more powerful than regular trolls with tougher skin, sharper claws and teeth, and greater strength and endurance.

Not once but twice, he defeated them and obtained the teleportation scroll. However, for the time being, he did not go to the higher floor.
