Han Li swept his spiritual sense over the wooden box, then gently touched it with his fingers, silently pondering.
After a moment, he suddenly opened the lid of the wooden box, and with a "whoosh" sound, a jet-black bead flew out.
This bead spun rapidly in front of Han Li, then transformed into a burst of black cloud of light, disappearing in a flash without a trace.
Almost simultaneously, Han Li felt a slight itch in the palm of his hand.
A thought crossed his mind, and he suddenly raised his hand.
Only to see a few strange small characters appearing in his palm, as tiny as grains of rice, faintly discernible.
Han Li glanced at them, and his wrist shook.
With a flicker of green light, the small characters vanished without a trace.
After pondering for a while longer, a green light enveloped his body, transforming into a green rainbow that flew out of the silent cultivation chamber, circling once before shooting straight towards the cave dwelling's gate.
