Always, the lord of Wuwang City sought ways of rushing from the underworld to retrieve the pen tip, but the journey was perilous with spectral beings scattered everywhere. The ghosts he dispatched were usually killed en route.
These ghosts weren't strong; even if they reached the vicinity of the pen tip, they couldn't get close.
In Wuwang City, he was the only true master, but he couldn't leave Wuwang City by far.
He had once asked the experts from the mortal world to search for the pen tip, but it was more often disastrous than not. Even if some survived and returned, they were still too far from the pen tip and had to turn back.
Moreover, the returning experts, due to the severe erosion of the yin energy from the underworld, often died within a few years.
