As soon as Chen Mobai said this, he extended his right index finger, and a golden fireball the size of an egg lit up at his fingertip before quickly condensing into a faint white glow.
Hong He immediately recognized it; this was the supreme realm of the Red Flame Sword Jue, the Extreme Sun Slash.

This indicates that this Rank-4 talisman sword has reached peak mastery, perfected in every aspect.
