Gu Yuan's heart stirred, and he took out the Spirit Treasure Black Tower.
Perhaps because it contained an artifact spirit, this Spirit Treasure was now calm and motionless.
Of course, the main reason was that the artifact spirit within was extremely weak.
Only then did Gu Yuan have a chance to scrutinize it carefully.
This Spirit Treasure, at first glance, seemed unremarkable, with six layers, seemingly forged from a peculiar black divine gold, adorned with various sized holes and damaged areas, especially the fifth and sixth layers, which were severely damaged.
Yet, despite its condition, this Spirit Treasure Tower emitted a faint aura, sending chills down one's spine.
Moreover, Gu Yuan clearly noticed that certain parts of the Iron Tower were engraved with images of Yaksha Demons, ghostly monsters, fierce beasts, and wicked birds, all engaged in mutual slaughter and devouring, appearing extremely fierce.
