Wang Baole grabbed a handful of his hair tightly, and a look of stubbornness and determination was apparent in his eyes. The more he failed at developing and researching the bead capable of storing the Mystic Trace Fog, the more indignant he felt.
He knew well that the bead would likely lose its function when he left the moon. However, it was his trump card within the Mystic Luna Realm. It was something that could allow him to move freely inside the realm.
If he met with a ferocious beast that was an inhabitant of the Mystic Luna Realm, he could use it on himself to escape; if he met with cultivators from other factions, he could use it on them and send them away.
A function like that set the value of the bead highly in Wang Baole's heart.
