Hei Jiao's heart suddenly filled with a trace of astonishment.
To think that the Nine Revolutions Jade Spear in his hand, a supreme Immortal Treasure gained from a great fortuitous encounter in the past, possessed such unmatched and formidable might.
The reason he had been able to travel through various Secret Realms for so many years while stably cultivating to his current realm, was largely attributable to the Nine Revolutions Jade Spear.
However, in the face of that small black banner, even a supreme Immortal Treasure felt fear, and during the clash, it nearly crumbled instantly upon contact.
This was the first time Hei Jiao had encountered such a situation.
The next moment.
As if a bolt of lightning had crossed his mind, an unfamiliar term abruptly sprang up from the depths of his heart.
Postnatal Spiritual Treasure!
Indeed, only the legendary Postnatal Spiritual Treasures could possess such terrifying power!
But—
Hei Jiao found it somewhat unbelievable.
