"Small chiliocosm core!"
Lin Feng could tell at a glance that this was the "Sky Horn" unleashed by Chiliocosm Sovereign Sky Horn. Actually, this should be the Sky Demon's Horn. It was a supreme treasure that had been severed from the body of Chiliocosm Sovereign Sky Horn when he transformed into a universe.
Chiliocosm Sovereign Sky Horn once came from a clan of Sky Demons back in the small chiliocosm. Later, when he became a Chiliocosm Sovereign, he used this Sky Demon's Horn as the small chiliocosm core, nurturing it day and night.
The current Sky Demon's Horn had already been nurtured to a terrifying level. The Sky Demon's Horn was famed for its sharpness in the first place, and was indestructible. After turning the Sky Demon's Horn into the small chiliocosm core and nurturing it for countless years, its sharpness had been developed to the extreme.
