Even in the undersea world, where the water pressure and resistance are immense, Yun Zong's sword strike was still awe-inspiring.
A dull thud echoed.
The entire sea floor seemed to tremble slightly.
The two of them felt a ringing in their ears.
In their line of sight, that stone door didn't budge at all.
Yun Zong's expression changed, astonished, "How can a mere stone door be so sturdy?"
Linglong said, "Let me try."
She wielded her magic sword and slashed fiercely at the stone door.
Boom!
In the muffled sound, the sea floor trembled lightly again, yet countless specks of dust spilled from around the stone door, turning the surroundings murky.
However, as the two waved away the murkiness, the stone door remained motionless.
But it did bear two deep sword marks.
The two exchanged a glance, seeing shock in each other's eyes.
With their cultivation, using their life-bound magic swords, a sword strike's power could not split a mountain, but any stone should be shattered.
