However, those three treasures that could be refined into supreme Innate Spiritual Treasures couldn't become stronger with the help of the main vein—it was beyond the main vein's limit.
Now, there is only one Ancestral vein left in the Prehistoric World, located under Mount Kunlun, which is beyond Jiang Chen's reach. Of course, even the Eastern Ancestral vein under Mount Kunlun is not as powerful as the Prehistoric Ancestral vein beneath Mount Buzhou back in the day.
This is the true foundation of the Chaos World, which can even nurture Innate Treasures. And these two Ancestral veins from the East and West, even at their peak, only reach as high as becoming supreme Innate Spiritual Treasures.
Mount Buzhou could nurture Innate Treasures; there was no doubt about that. If the Prehistoric Ancestral vein within Mount Buzhou were still present, and Jiang Chen buried his three treasures down there, they would absolutely become three top-tier Innate Spiritual Treasures.
