Inside the Blood Stone Mine, there was a two-way Space Channel connecting Qingtian Fortress and the Blood Stone Mine.
Yet this formation was rarely activated. Once activated, it required over ten thousand Blood Stones to open. Within the Blood Prison, the spatial laws were even more chaotic, making long-distance spatial teleportation a hundred, even a thousand times harder than in the outside world.
Normally, it would not be opened unless something major happened. But at a time like this, who still cared about such rules?

They had barely found their footing when countless cries reached their ears from afar. Looking out, they saw an endless horde of Blood Demons frantically attacking Qingtian Fortress.
"Gasp, it's a Blood Demon Tide!" The old steward's expression changed at once. He had thought the Blood Stone Mine was dangerous enough, but compared to a Blood Demon Tide, it was nothing at all.

He finally understood why everyone turned pale
