The blood-colored butterfly was Die Yue's phantom!
In the battle at the Great Qian Ruins previously, the appearance of this blood butterfly phantom was also the reason why Su Zimo was able to kill the number one Perfected Being of the North Region, Xi Wuya, domineeringly and rise to fame!
Initially, Su Zimo had no idea why the blood butterfly phantom would appear.
It was only earlier on that he finally realized - the blood butterfly phantom should be the ultimate phenomenon of his bloodline!
Right now, half of the blood butterfly was illusory and incorporeal.
Su Zimo had a hunch that the blood butterfly would only truly materialize and release its true strength after he had cultivated to the final step of the Mystic Classic of the Twelve Demon Kings of the Great Wilderness and conjured all 12 demon kings!
From high and above, the God race leader looked down at the blood butterfly behind Su Zimo with a shocked expression!
