While Ye Xiao was shocked to learn about a man hiding in the shadows, Morning Stars suddenly contacted him and told him not to worry about the location of Worms. Since those Worms are living in the Morning Stars, it knows their every location.
And the same goes for the Heavenly Demon hiding in the dark.
It is just that this Heavenly Demon is quite special. It sometimes appears in the range of Morning Stars and sometimes disappears.
It appears only when the Heavenly Demon is contacting those high-leveled worms, and then disappears from the Morning Stars' senses.
Although Ye Xiao was astounded, he did not ask or say anything. Instead, he focused on the Worm standing opposite to him and asked coldly, "Then tell me, do you know anything about the origin of you Worms? Do you know who created you? Do you know about your relationship with Heavenly Demons?"
