A small black orb appeared in front of Fang Yu, which she pushed towards Beleth's chest!

This was Fang Yu's third Cosmic Ability, Star of Death!

By this point, a pattern could already be seen on Fang Yu's cosmic abilities.

Each of Fang Yu's cosmic abilities depend her Celestial Rebirth.

Fang Yu's first Celestial Rebirth had her transforming into nebula and a young star. This coincided with her First Cosmic Ability, Call of the Starlight.

Fang Yu's second Celestial Rebirth had her transforming into a giant red star. This was mirrored by her Second Cosmic Ability, Star Emperor Manifestation Art.

Meanwhile the third and latest Fang Yu's Celestial Rebirth had her transforming into a black hole.

Looking at that can already tell someone what Fang Yu's 'Star of Death' was.

Yes, it was a miniature black hole.

Of course this blackhole was not comparable to the real black holes out there. It will take Fang Yu a higher cultivation base to allow her to do that.
