Battling a Sea of Knowledge cultivator (part 2)

Constant thunder like sounds followed by flashes of golden light and green smoke, kept appearing in on the sky with each clash of Dry Bone's spear with Aster's sword.

With each clash, Dry Bone felt his hands getting number, and the small cracks on the tip of his spear getting bigger.

"Why, why can't I kill you!", he shouted, pouring more of his spirit energy into his weapon and stabbing it towards Aster.

"Clang!", the sound of metals colliding echoed through the sky and for the first time Dry Bone managed to make Aster step back by a couple of meters.

As Dry Bone was about to smile, his expression froze as he noticed his spear's tip was pushing against Aster's stomach, without being able to pierce his skin, he deliberately aimed at the area where there was no armor, but the result wasn't what he expected.
