At this moment, within the Blood Sky Secret Treasure.
Zhou Yu and the others were following Zhang Qin, searching for the inheritance left by the Blood Sky Sword God.
However, they had barely searched for half a day when suddenly the entire secret treasure began to shake violently. Dark Demon Qi erupted madly from the underground in all directions, and in the blink of an eye, it completely covered the whole sky.
In less than half an hour, the Blood Sky Secret Treasure was entirely shrouded in darkness.
It was as if the most violent storm was about to break.
Witnessing this scene, Zhou Yu and the others were stunned.
Even a fool could see that something earth-shattering had happened in the Blood Sky Secret Treasure, otherwise how could it suddenly become so terrifying.
"What's happening?"
Zhou Yu immediately looked at Gu Zifeng.
After all, Gu Zifeng was the one most familiar with the situation in the secret treasure.
