"Whoa!" he whispered in surprise. "So, the Spirit Essence was holding it together?"
[Seems like it was.]
Feeling a bit mischievous, Lu Sheng picked up another pebble, this one glowing even more brightly than the rest. "What if I try the Formless Weapon Art on this pebble? Think it'll work?" he mused aloud.
[Of course it will,] the System responded. [The Formless Weapon Art doesn't require a weapon. It can be applied to anything. In fact, at higher cultivation, it won't need any base object at all.]
"You're the best!" Lu Sheng grinned, excited to test his theory.
He glanced at the pebble in his hand and felt a surge of curiosity. Could it work? Clenching his fist tightly, he focused and executed the Formless Weapon Art. The pebble crumbled into dust almost instantly, the Spirit Essence within it consumed in a blink. For a moment, he thought his attempt had failed. He could feel the fine grains of dust in his hand, lifeless and inert.
