With the help of the mystic vestment robe, Shen Yi had a clear grasp of the whereabouts of every living creature around him.
Apart from the minor demons who came out of curiosity to observe, the hidden figure of Thunderhoof Demon Emperor in the sky had already been fully exposed.
What puzzled him more was the fact that none of the Demon Emperors from the top ten caves had shown up.
Could they not move about that easily?
Shen Yi had a vague guess in his mind, but he did not relax his vigilance.
The previous surreptitious glance of the roe demon toward the sky was unlikely to be at Thunderhoof; perhaps that group of Great Demons had other means of surveillance as well.
This was somewhat unfortunate.
He had originally planned to seize this opportunity to slaughter these two demons together.
