The Blood Cloud seemed to have dissolved the ghost that had charged first toward the rear mountain. The grand formation stretching from the mountain gate to the rear mountain also activated in a chain reaction with the first ghost's dissolution. Vast swaths of blood mist billowed up all around, as if staining the entire world red!
The army no longer dared advance. Instead, it fell into a panic. There were still many soldiers near the grand formation, and the weaker ones were the first to collapse. With a bang, they transformed directly into clouds of blood. Their energy then sank entirely into the formation, gathering into a pulse-like crimson torrent that surged toward the rear mountain.
It was not only Zhou Shan who was aghast. Even the Ghost King and several miscellaneous kings suddenly changed color. Faced with such an overbearing and fiendish formation, no one could remain calm.
The underwater army descended into chaos. Seeing their companions suddenly turn into clouds of blood mist, they all paled and hurriedly fled beyond the formation. The terrifying Blood Cloud continuously drained the power of low-level Ghost Generals and even Ghost King-level ghosts. Once they were completely absorbed, they would turn into blood clouds and vanish from the world.
Although using a blood sacrifice to power the formation severely damaged one's virtue, this was wartime. Mercy toward the enemy was cruelty toward one's own side. Looking back along the way, the number of vanished enemies kept increasing. Zhou Shan had already organized a retreat, while the two Ghost Emperors still pursued me relentlessly, seemingly feeling that the Blood Cloud Formation had little effect on them.
It was obvious that even after the Blood Cloud Formation was deployed, it was not particularly effective against ghosts above the Ghost King level. Trouble would arise
