Wang Wu stood at the edge of the desert, thought for a moment, and decided not to go personally; his true form would not leave the protection range of the Hidden Origin Bell.
However, at this moment, he still had three top-grade hairs. He took out one, transformed it into the Hao Mao Monarch, then separated a trace of divine thought. In an instant, it silently crossed that invisible boundary and headed straight into the desert.
Wang Wu's true form then casually used a Ruyi Body Technique, transforming into a speck of dust, waiting at the original spot, serving as a signal relay station.
Otherwise, if too far, he wouldn't be able to sense or contact that trace of divine thought.
A moment later, the Top-Grade Hairs Monarch had already ventured tens of thousands of miles deep, and Wang Wu finally started to see some scattered escapees appearing like refugees, some human, some demons, but temporarily no sign of spirit monsters.
