915, shocked the whole audience

"You want the [Whirlwind Core]?" King of Cyclone, Ashad, stiffened at the figure.

The [Whirlwind Core] was not just any object, it could be considered the single most important thing in the entirety of Cyclone City.

The reason why Cyclone City could float in the sky was because it relied on eight huge Seventh Order Legendary [Whirlwind Cores] at the base of the city.

The [Whirlwind Core] not only provided the entire city with the ability to float perpetually in the sky but also served as the power source for the functioning of the entire city.

The ultimate mission of the elemental beings in Cyclone City was to supply energy to the [Whirlwind Core], producing and replacing the new [Whirlwind Core].

And now, Su Yu had casually asked to take one...

…

"Adventurer," Ashad said in a very calm tone, "since you know of the [Whirlwind Core], then you must surely understand its significance to our entire city, yes?"

"Of course, I do." Su Yu nodded with a smile.
