Chenglong Pass.
The sky had been completely obscured by that enormous wave. Beneath its vast shadow, endless "mysteries" roared as they surged toward the towering black city wall.
Fang Zuo and the others stood atop the wall, their dark crimson cloaks soaked by seawater. His hand rested on the straight blade at his waist, unconsciously rubbing its hilt as his mind raced.
"They're here..."
Fang Zuo muttered.
Over a thousand "mysteries"—the combined pressure of their realms alone was enough to leave everyone within Chenglong Pass struggling to breathe. Coupled with the towering waves and the unceasing, thunderous roars, the scene before Chenglong Pass resembled the end of the world.
Amid the howling wind and torrential rain, Fang Zuo raised the walkie-talkie in his other hand and spoke calmly:
"Activate the 'Chenglong' firepower line."
As soon as he spoke, heavy steel plates across the enormous black iron wall retracted into its body. Like a honeycomb, vast black openings appeared across the wall's surface, arranged in orderly staggered rows.
Then, cannon barrels extended from those openings, densely packed across the steel wall. Their muzzles turned in unison, all aimed at the incoming Beast Tide that filled the sky.
BOOM BOOM BOOM BOOM—!!!
Blinding, concentrated flashes erupted one after another from the honeycomb-like cannon barrels.
Endless artillery fire formed an airtight net, instantly blanketing the entire sky.
The dim sea was illuminated as bright as day.
Ordinary light weapons, such as guns and grenades, found it difficult to affect high-level "mysteries." At most, they could deal with weaker "mysteries" below the "River" realm.
Heavy weapons were different. With their devastating explosive power, they could injure "mysteries" of the "River" realm and even some of the "Sea" realm. In sufficient numbers, they could even threaten an "Infinity" realm creature.
As a Class A pass
