The next day.
Eternal Night New Calendar, Year 04, April 5, afternoon.
The Nine Heavens Lightning-Inducing Tower was officially completed and about to undergo its first test activation.
Chen Fan stood on the Black Tortoise Plains, gazing at the enormous structure ahead. Individual Cuboid Spaces were connected together, rising from the ground and covering a vast area.
This was the "Nine Heavens Lightning-Inducing Tower"!
The Mortal Domain's masterpiece.
"Domain Lord."
Eight Hundred ran over to report, "Everyone is in position. Every member stationed at a post that requires operating an exotic treasure has had a miniature Heavenly Thunder Formation inscribed on the web of their hand, ensuring they can receive Thundercaller's instructions at any moment."
"Good."
Chen Fan nodded slightly and, under everyone's gaze, said softly, "Activate."
The next moment—
The first cubic chamber activated.
The collision between the Heavenly Thunder Formation and the exotic treasure produced the first bolt of "Pocket Silver Lightning." Then the second Cuboid Space, the third, the fourth... lit up in a precise, orderly sequence.
Number-15 Heavenly Dao, "Thundercaller."
It precisely controlled the activation and deactivation of the Heavenly Thunder Formations, transmitting information directly to the Mortal Domain members responsible for operating the exotic treasures. More accurately, it was not transmitting information, but controlling their muscles through electrical currents, allowing them to activate the exotic treasures instantly, with almost no delay.
The entire process was fully automated.
Every delicate operation within the hundred Cuboid Spaces was entrusted to the Heavenly Dao, Thundercaller!
Until—
As the Cuboid Spaces continued lighting up one after another.
Chen Jiutian and Zhang Qianqiu stood nearby, their bodies tense, their fingers clenching involuntarily as they stared fixedly at the enormous structure ahead.
The "Nine Heavens Lightning-Inducing Tower."
The ninth floor, the tenth, the eleventh...
The twelfth floor, the thirteenth, the fourteenth.
