Perhaps there had not been enough time, and the prison guards had feared that the others arriving on their heels would block their escape just after they finished dealing with the prisoners. They had not taken that course.
Golden Core cultivators possessed far more divine abilities and means than low-level Qi Refining and Foundation Establishment cultivators, so Black Mountain Immortal Prison clearly took them much more seriously.
The cells served as the first layer of restraint.
The entire Underground Third Floor was built from spirit materials and reinforced with all manner of runes, forming a second layer of restraint. It was practically a fortress of copper walls and iron ramparts.
Under these circumstances, there could be no secret passages nearby. The entrance they had come through was the only exit.
That was what gave them a chance to carry out the rescue.
Otherwise, after dealing with the prisoners, the prison guards could simply have escaped through a secret passage without facing the intruders.
"Rescue them."
Standing spear in hand, Liu Yu gave the order calmly, his expression composed.
As he spoke, his gaze kept sweeping around, examining the layout of the Underground Third Floor.
The moment his words fell, Guo Poyun and the others moved, unleashing their treasures to bombard the cells.
Without knowing the special hand seals needed to open the cells or understanding their formations and mechanisms, smashing them apart with treasures was the most direct and fastest method.
Bang! Bang! Bang!
An unbroken succession of booms immediately rang throughout the entire Underground Third Floor.
"Fellow Daoists of the Purple Turban Army, Elder Qingshui entrusted us with coming here to rescue you."
While breaking open the cells by force, they first transmitted messages through divine sense to exchange the secret passwords and avoid unnecessary misunderstandings.
