章 131: Chapter 128 Eternal Heavenly Curse

"Not good!"

In the high building, Tan Qingquan's face changed dramatically.

The flying sword controlled by the Yin God spun swiftly, rushing towards the heavens.

With white waves scattering from the sword tip, its speed abruptly soared to nearly a kilometer per second, attempting to shake off the laser-like Flying Fire Meteor shooting at it.

This speed...

Surpassed the velocity of Short Range Defense Cannon projectiles.

It's known that the length of a flying sword is often less than one meter.

And its maximum speed reaches a kilometer per second.

A target of one meter traversing at a speed of a kilometer per second, for the Short Range Defense Cannon to form a hundred percent interception barrage is like dividing one thousand by one, which means a bullet interception ratio of only 0.01, requiring thousands of bullets to be poured out in one second to completely eliminate such a target.
