After careful consideration, Chen Feng decided to start by setting up a plan around the small mountain. He moved through the mountains like a ghost, constantly throwing out various precious materials and magical treasures.

As time went by, one after another, exquisite arrays gradually took shape. These arrays echoed and intertwined with each other, eventually forming an extremely large array cluster.

This array formation covers an area of ​​ten kilometers in radius, and its power is astonishing.

Moreover, the power contained within the entire array cluster has reached the terrifying level of the mid-stage of the fourth rank!

This means that unless a powerful expert of the upper three ranks personally takes action to break it, even a martial artist of the fourth rank can only sigh in despair at this indestructible array and is completely unable to break through its constraints.

A cold light flashed in Chen Feng's eyes, and his voice was deep and firm: "Enter the underground stronghold and slaughter all life inside, including sea beasts."

His commands were like a chilling wind, sending shivers down one's spine.

Chen Feng's body gradually disappeared into the formation, as if blending into the surrounding environment.

His eighteen clones appeared like ghosts, each radiating a powerful aura. The clones moved in perfect unison, as if controlled by a single person.

They wielded various weapons, some sharp longswords, others gleaming daggers, and still others mysterious magical artifacts. Their steps were light yet steady, as swift as a cheetah.

Nine servants followed closely behind, their expressions solemn, their eyes revealing absolute loyalty to their master. Working in coordination with their clone, they formed an impeccable fighting team.
