The firepower of Illusion City is extremely powerful. With just one round of salvo, a small city like Mechanical City would be flattened in an instant.
This power is even stronger than Su Yu's current strength!
After all, this isn't just one person, but an entire city unleashing countless war machines at once.
No wonder Xie Yitian dared to invite Su Yu to Illusion City.
The defensive power within this city is indeed formidable, worthy of being the stronghold of a seven-star powerhouse for over a hundred years.
Even an eight-star powerhouse might be held off!
Su Yu's Mechanical City, after all, was just recently established and doesn't have such a deep foundation.
"Tsk tsk, really impressive…"
Su Yu, high in the sky, couldn't help but click his tongue in appreciation at the enormous commotion that erupted the moment he revealed himself.
He just released a bit of his invisibility, actually wanting to test the strength of this Illusion City.
