Gulu...
A large number of bubbles appeared in the magma beneath the fortress, and the Empire's army also noticed the change.
Carlos smiled. Things were proceeding according to his plan.
"After waiting so long, it's finally ready. Anna, go."
Carlos did not know who he was speaking to.
"Mm."

After roughly several dozen seconds, the magma bubbling beneath the fortress stopped churning and began showing signs of solidifying.
Crack, crack.
The congealed magma split apart, the cracks forming not randomly but into a large interconnected alchemical array.
Boom, boom, boom...
The ground within a radius of more than ten kilometers began to tremble.
Bang!
The already-solidified layer of magma ruptured. Magma with an even higher temperature surged through the cracks, spraying outward like fountains.
Gulu...
The magma flowed down the slope, and the Empire soldiers not far away immediately retreated.
The magma continued surging upward and flowing down the slope. In just a dozen seconds, a roiling magma slope had formed beneath the fortress.
At the rear of the battlefield, Carlos's adjutant stood on high ground, watching the magma slope. He held a black stone tablet in his arms, its surface engraved with an extremely intricate alchemical array.
