Blood Hidden City, Divine Craftsman Refines Treasures

The core territory of the Thunder Ancient Kingdom, the Ten Thousand Thunder Plains.

There were no vast misty waters here, only eternal thunder.

Above the heavens was not a clear sky, but billions upon billions of rolling dark purple thunderclouds, like an inverted ocean of lightning. Thick electric serpents danced and exploded within them, letting out deafening roars as they endlessly poured destructive thunder power onto the boundless plains below.

The ground was not merely soil. It also consisted of dark purple "Thunder Strike Divine Iron," forged through endless ages of thunder bombardment and tempering. It was incomparably hard, with fine electric sparks flowing across its surface.

The air was suffused with dense Thunder Aura. Every breath carried a faint numbing sensation, yet it also made experts cultivating the laws of thunder feel incomparably comfortable.

At the heart of this thunder-ravaged plain stood a magnificent giant city—Blood Hidden City!

The entire city seemed to have been piled from billions of enormous, sharply angular pieces of dark purple Thunder Strike Divine Iron. Its walls soared into the clouds, covered in naturally formed thunder runes that constantly absorbed the lightning descending from the sky, forming a flowing, "sizzling" membrane of thunderous light over the city walls.

The buildings within the city were rugged and heavy, mostly constructed from massive divine iron pillars and thick thunder stones. Their lines were stark and hard, filled with a sense of power and an Aura of Destruction. Countless thick bolts of lightning shot from the top of a sky-piercing "Thunder Guiding Tower" at the city's center toward the heavens, connecting with the thunderclouds above to form spectacular pillars of light. They guided the violent thunder power into various places throughout the city, converting it into pure energy.
