470 Impossible Feat

"What's going on? Why are we attacking our own people?"

"Whose order was that? This is impossible!"

"Quick! To the control room!"

The Grans rushed to the control room anxiously.

Yet, as they were on their way to the control room, countless auto-defense weaponry started to rain hell from above!

In the past, these weapons would be attacking the intruders and enemies. Now, they fell to their own weapons.

Qin Feng took control of the city's defense system and started to slaughter the rest of the Gran population.

In just 20 minutes, the rest of the Grans, about 10,000 of them, were all slaughtered by their own weaponry. It was a massacre! 

Then, when there were only a few Grans left cowering in fear, Qin Feng then piloted the Floating City away from Longchuan City.
