The word " sacrifice " on the mountain-like coffin began to glow. At first, the glow was hazy, illuminating the entire void. Then, the glow began to rotate slowly, turning into two colors-black and white. Gradually, it transformed into the shape of a Tai Chi diagram. The Tai Chi diagram gave Xia Pingan the feeling that it was a misty spatial passageway.
Xia ping 'an was also extremely shocked. He didn't expect that by adding his soul power into the emperor's sword and killing those corpse bugs, it would actually cause a change in the giant coffin. When he was exploring the giant coffin before, he had actually injected some soul power into it, but there was no reaction.
Perhaps killing the undead bug would cause these changes.
No matter what, this was a good thing.
