Lu Changfeng spotted the undercurrent, activated the Six Void Circulation Art, and leaped in.
Splash-
The seawater parted on its own, opening a space three feet across around Lu Changfeng.
He sank slowly, the circulating water force controlling the sea around him without letting a single drop touch his body.
The light dimmed little by little.
The sea's surface grew ever farther above his head, like a blurred mirror reflecting the gray sky.
The surrounding water changed from pale blue to deep blue, then from deep blue to inky black. Shoals of fish swam past, curiously studying this uninvited visitor to the deep before quickly scattering.
He had no idea how long he had been descending.
At the seabed, Lu Changfeng saw a flight of steps stretching downward toward a barrier at its end.
The barrier had two layers.
The outer layer was a curtain of water that kept out the sea and maintained the air and pressure within the city.
This ancient barrier was the work of the Yanshi Lineage. Powered by the spiritual qi of mineral veins beneath the seabed, it required almost no human maintenance and had operated for over a thousand years.
The inner layer was a ward against intruders. Anyone who forced their way inside without a Dragon-Slaying City token would trigger it and summon the city's defenders.
As for tokens...
Having captured so many people, Lu Changfeng already had more than thirty.
Although they differed, all they contained were the bloodlines of the four families' direct descendants and their innate true qi.
These included the Liu Family's Azure Heaven Dragon Transformation Art, the Xu Family's Profound Origin Life-Transformation Scripture, the Lu Family's Immortal Water Divine Art, and the Li Family's Exquisite Frostflame.
Beyond that, there were no special identifiers, nor was the barrier intelligent
