"This must be the spot, it appears to be the weakest point." Shen Luo's gaze quickly landed on a slightly recessed part of the jade. With a flip of his hand, he took out the Mother-Child Sword.
With a "clang," he summoned a subordinate sword and activated a spell.
A thin beam of sword-light shot out from the subordinate sword, piercing into the recess of the jade.
With a light "ding," the jade was punctured with a tiny recess, but not penetrated.
"This jade is incredibly hard!" A hint of surprise flashed in Shen Luo's eyes.
This subordinate sword was a top-grade magical instrument bound by a seven-layer prohibition. The sword-light it emits could easily penetrate a thick piece of iron, yet it could not penetrate this jade.
He pursed his lips, changed the magic spell in his hand, and the subordinate sword immediately started to rotate like a drill. The emitted sword-light also began to rotate rapidly and slowly penetrated the jade.
