"Once the city walls have been heated to over a thousand degrees, suddenly douse them with cold water, and the rock can be destroyed at once, becoming as brittle as an eggshell."
"So even with its magic arrays, the Holy City's walls were utterly destroyed."
"Because burning and flooding do not count as extraordinary power, the damage they inflict is limited. Only through sustained damage could they affect the city walls."
"That was the key to how I destroyed the Holy City's walls!"
Nalant slowly explained why the city walls had collapsed.
In truth, this was also his first time using this method. Although he had seen some novelty bloggers introduce it online in his previous life—
He had never tested it himself. Who knew whether it was real or fake?
And even if it was real, could scorching a single rock possibly compare to scorching an entire city wall?
Thus, only at the moment the Holy City collapsed did Nalant finally lay all his worries to rest.
As for why he had felt that he had already succeeded after the floodwaters submerged the walls—
That was because, with his far sharper eyesight, he had already seen faint cracks appear along the waterline of the walls.
The cracks had not begun to spread at the time, so the high priests of the allied forces of the various divine kingdoms had been unable to notice them.
"After burning it, pour cold water over it immediately, and stone can become as brittle as an eggshell?"
Still, Nalant's explanation was far too miraculous for these natives of the fantasy world.
Listening to it was not much different from not listening at all.
Seeing this, Nalant simply picked up two fist-sized stones from the ground.
He then summoned magical flames and began roasting them.
