"Boom!"
A terrifying surge of spiritual energy erupted violently from the old man's body like a suddenly exploding volcano, compressing the surrounding space until it began to warp slightly.
At that moment, the old man resembled a bottomless sea of fire. The Fire Spirit Ancestor, the Fire Spirit Clan's mighty Late Spirit Grade Heavenly Sovereign, glared furiously at Jiang Yun.
"Junior, how dare you! How dare you!"
"Heh, I heard the Fire Spirit Clan stood unrivaled in the Great Thousand World in the art of flame and possessed wondrous divine flames. As it happens, I, Jiang Yun, also specialize in the path of fire, so I came to seek your instruction. But now that I've seen it, you're nothing special!"
Jiang Yun looked disdainfully at the members of the Fire Spirit Clan, and a vast, imposing chuckle suddenly rang in the ears of every Fire Spirit Clan expert present!
That feat alone caused countless Fire Spirit Clan experts to pale abruptly. Such a terrifying display seemed faintly superior even to their Ancestor's abilities.
"Good! Good! Good!"
"My Fire Spirit Clan was born to command the path of flame, yet someone actually dares challenge us in this field. I shall grant your wish and let you witness the methods of my Fire Spirit Clan!" Jiang Yun's contempt made the Fire Spirit Ancestor laugh in extreme fury as he shouted sharply.
"Rumble!"
As his words fell, a vast expanse of space behind the Fire Spirit Ancestor suddenly collapsed. A boundless ocean of crimson spiritual energy swiftly emerged from the void. It was his Supreme Sea, the essence of a Heavenly Sovereign's lifetime of cultivation.
Countless raging volcanoes erupted within the Fire Spirit Ancestor's crimson Supreme Sea, their violent spiritual energy fluctuations squeezing space until it seemed to wail.
"Flame Seals the World!"
