Do you obey?

True Monarch Yellow Mountain immediately gave Song Shuhang a call, but after listening to a melodious caller tune that played over and over again three times in total, all he heard was, "I am sorry, the person you are trying to reach is currently unavailable. Please try again later!"

He hung up in frustration, ‘What is little friend Shuhang doing? Why isn’t he picking up his phone?’

At this moment however, Song Shuhang was busy making a contract with the ghost spirit. His phone was in silent mode, so of course he couldn’t receive the call.

What should I do, should I try to send him a message via the thousand mile sound transmitter? True Monarch Yellow Mountain thought to himself.
