Chapter 130: Asura Slaughter Blade!_1

Fang Ren's gray vital energy, which he had previously retracted from the red aura, suddenly exploded once again at this instant.

The patterns were more complex, with specks of light scattered within, and though they resembled silk threads, vital energy was still an aura by nature; it's just that no matter how much it dispersed, it followed fixed patterns.

As the gray vital energy erupted once more, Fang Ren's arm, which had been gripped by the test subject, directly snapped apart, and his blood sprayed onto the face of the test subject.

Bang!

With a loud noise, Fang Ren used the arm that had broken off in the middle to strike the head of the test subject, using his own arm bone to send the skull flying away.

The test subject also lost its life force in an instant.
