Eren stood in disbelief, staring at the fist-sized hole on the right side of Li Yunfeng's chest.
What shocked him wasn't just the wound in the Frost Demon's chest, inflicted by his mana bullet. It was the fact that the wall behind Yunfeng was also inflicted by a similarly sized hole.
The mana bullet hadn't merely passed through the Frost Demon's chest, but it had also penetrated the Qi-reinforced frost walls as well.
The bullet continued its relentless path, carving through one wall after another before finally vanishing as the mana finally dispersed at the range of a few hundred meters.
Even Eren was taken aback by the strength of the mana bullet. Why did it feel less like a gun and more like a frightening artifact?
He was fortunate that the palace was much larger, otherwise he was sure that the bullet might have left a hole in the outer wall of the palace as well.
