Di Xin Gravity Array

In the sky outside the city, Tang Chengyun, who had been observing the situation within the city, frowned slightly.

"Di Xin Gravity Array?" he murmured.

It was a type of formation whose purpose was to alter the gravity within an area, making it difficult for the living beings inside to move.

Earlier, this formation had not been called by this name, and its power had been quite limited. At most, it could only create tenfold gravity.

More than thirty years ago, the current Di Emperor—Di Xin—had improved the formation, greatly increasing its power until it could even reach hundreds or thousands of times normal gravity!

Under such gravity, living beings below level 40 would be crushed straight into meat paste.

Even living beings above level 40 would find it difficult to take a single step.

From then on, the formation had been renamed—the Di Xin Gravity Array.

To set up the Di Xin Gravity Array, one needed a material called the Earth Core Divine Stone. It was incredibly rare. Tang Chengyun had lived for so many years, yet he had only ever seen one on the Di Emperor.

This was equivalent to the Di Emperor carrying the Di Xin Gravity Array around with him. Back in Flowing Cloud City, Nan Feng and Long Wudi had been pressed deep underground by terrifying gravity for exactly this reason.

Tang Chengyun had not expected to see such a rare treasure in Wu Hai City.

It seemed the Zhao family had prepared thoroughly in order to win this battle.

"This Earth Core Divine Stone shouldn't be large. The gravity it produces is far weaker than the Di Emperor's," Tang Chengyun thought to himself, with no intention of stepping in.

Gravity of this level would not have much effect on Nan Feng and Xiao Luo.
