All of the white skulls let out a howl and spat out green phosphorescence flames as they charged towards Han Li. Naturally, after they rushed several tens of feet away, countless golden threads appeared and quickly flashed past.
However, this time, a different situation occurred.
After the golden threads swept past, although a few thin cracks appeared on the surface of the skulls, after a green light flashed, they healed as if they had not suffered any damage. The skulls were not hindered at all and continued to pounce on Han Li.
When Han Li saw this, he was stunned at first, but then he understood. These ghost skulls were no longer made of flesh and blood. He did not know what kind of strange ghostly body they had been refined into. Although his sword threads were powerful, the other party had become invisible and was not harmed by swords and sabers. Naturally, he could not kill them.
