The Upper Qing Saints truly went all out, using the fragments of Mount Buzhou as basis, the God-killing Array of the Dutian as matrix, and the Creation Green Lotus as the eye of the array; they gathered the powers of Heaven and Earth from all directions, and successfully refined a top-tier Innate Spiritual Treasure.
A method like this truly evokes admiration and yearning.
Unfortunately, even after all this, the Upper Qing Saints still didn't get what they wanted. After all, the Heaven-Opening treasures, which are the strongest magic treasures in the Prehistoric World, can't possibly be artificially refined, not even by saints.
Holding the twelve divine swords in his hands, Jiang Chen quietly examined them. Separately, these twelve divine swords are only mid-tier Innate Spiritual Treasures, but combined, they become a top-tier Innate Spiritual Treasure. Their power is perhaps even greater than that of the Taichu Divine Sword.
