Two years ago, when the situation was at its most dire, the Mountain Gate was besieged and encircled by demonic forces.
The Ghost Spirit Sect Cultivators surrounded the Mountain Gate and laid down an Evil Array. They connected it to the Earth Fire and summoned countless Evil Ghosts, transforming a blessed Immortal Land into a vicious Ghostly Realm.
Clearly, the Ghost Spirit Sect was preparing for a war of attrition.
The two Sects had been rivals for hundreds of years, so they were naturally well aware of the details of the Qingfeng Sect's Mountain Protection Array.
A Tier Three Top-Grade Grand Array, the Duality Illusion Moon Array.
As long as a Core Formation True Man presided over it, or it was fueled by enough Top-Grade Spirit Stones, it was simply impossible to breach unless an overwhelming force appeared.
Thus, the Ghost Spirit Sect's strategy was a long-term siege: plunder resources and destroy the Spirit Vein.
