The blood-stained brass seal was a superior-grade spirit treasure, and it exuded a powerful pressure. The moment it appeared, it had already sealed the area where Xuan Xin was, as if it could suppress the blue sky for eternity.
Xuan Xin's Black hair fluttered in the wind. He clenched his fist, and a crystal-like and dazzling light bloomed from it. Mysterious runes of catastrophe flickered under his skin. Then, he punched the brass-colored blood seal.
"BOOM!"
Accompanied by an earth-shaking roar, the brass blood seal was blown away on the spot. Its light dimmed and its spiritual power was greatly damaged.
As for Xuan Xin, he was completely unscathed!
With one punch, the power of a superior-grade spirit treasure was greatly reduced. This kind of divine power made everyone watching the battle from a distance gasp. It was indeed worthy of being an existence that could withstand the 99 world-destroying Heavenly Tribulation!
