622 Storm Imperial City!

Yue Zhong lifted his head to admire that floating structure, his eyes full of shock. This was the first large structure that was made entirely out of alloy. Even the Radiant Battleship, a Gold-Treasure, was not as big as this Storm Imperial City.

"What did they use? How could they achieve its anti-gravity? How much energy would this consume?" Yue Zhong could not help but wonder, as the questions ran through his head. Such a scene was still too shocking.

On Earth, Yue Zhong had also managed to produce something close to the Sky Fortress, and it was able to float. However, it required a huge energy source.

The floating city spanned over 30 km, and one could tell that it must weigh a lot with just a look. If such a structure wanted to float on this planet, which seemed to have twice the gravity compared to Earth, the energy consumption was definitely not little.
