Chen Yu was stunned, only to see Yang Fei's right hand suddenly withdraw a leather bag.
The mouth of the bag opened wide and was flung towards Chen Yu's face.
The bag was made from tanned human skin, with a tattoo of a menacing skull on it.
Inside the bag, there was a buzzing sound, and a wisp of black fog directly enveloped Chen Yu's head.
Upon closer inspection, the black fog was actually made up of billions of tiny insects.
The insects were so small that they were invisible to the naked eye, yet they exuded a violent and bloody aura that made one's heart tremble with fear.
Sorcery King's Gu Insects!
The Sorcery King was already dead, and these Gu Insects had lost their control.
They were fed with human flesh and blood, and now, without anyone to feed them after the Sorcery King's death, they were starving mad.
Chen Yu was stunned again.
Meanwhile, Yang Fei had already fled at the fastest speed, as if avoiding some malevolent demon star.
