Azure Mulberry Star, Heavenly Silkworm Mountains.
The Green Mulberry Mountains were an outpost of the Thousand Wood Sect. After cultivators of the Blood Flame Sect destroyed the Thousand Wood Sect, the Green Mulberry Mountains also fell under the Blood Flame Sect's control.
A great number of green mulberry trees grew here. Their leaves could be used to feed spirit silkworms, while the mulberries could be used in pill refinement, making them highly valuable.
The Blood Flame Sect lacked manpower, so it entrusted the Green Mulberry Mountains to the Hundred Herb Sect. The Hundred Herb Sect had three Void Refinement cultivators and a legacy of over ten thousand years, yet it had never managed to prosper. When the Blood Flame Sect invaded Azure Mulberry Star, the Hundred Herb Sect voluntarily submitted to them, acting as the tiger's accomplice and helping the Blood Flame Sect wipe out many resisting forces.
The Hundred Herb Sect had dispatched five Spirit Transformation cultivators to garrison the Green Mulberry Mountains. Liu Feng was one of them. With cultivation at the mid-stage of Spirit Transformation, he was also the person in charge here.
On this day, Liu Feng was cultivating inside a secret chamber.
A series of explosions rang out, and the secret chamber shook faintly.
Liu Feng frowned, hurriedly stopped cultivating, took out a yellow Communication Disk, and injected a spell into it. A panicked male voice sounded out. "Elder Liu, this is bad! Powerful enemies are attacking! They've already broken in!"
"How was the formation breached so quickly?" Liu Feng asked with a frown.
"They brought formation-breaking talismans. The formation has already been broken! Ah..."
Before he could finish, a shrill scream rang out, accompanied by another series of explosions.
The secret chamber began shaking violently, and long, thin cracks appeared across its ceiling.
