Just as Zhou Shu disappeared, a few figures descended from the sky.
If Zhou Shu was still here, he would definitely discover two existences he was very familiar with.
They were Demon King Ao and Tiangou.
"This is it!" Tiangou said in a low voice. "Liu'Er's scent suddenly disappeared here!"
Demon King Ao's expression darkened. "I received his message and immediately rushed over. I didn't expect that I still wouldn't be able to make it in time!"
"Did Liu'Er encounter some misfortune?" a Demon King said solemnly.
The expressions of the Demon Kings turned very ugly.
For many years, Demon Kings had been at the peak of the Demon Realm. No Demon King had ever been injured or died.
But now, it had only been a short while since something first happened to Tushan and then to Liu'Er. The whereabouts of two of the twelve Kings of the Demon Realm were already unknown.
So, who would be next?
