Castle Invasion

Frankenstein flashed forward with Abel's giant body towards the castle on the peak while the 6 mad knights were still battling with the wizards.

They were only 2 kilometers from the castle. With another kilometer, they would enter the attack range of the 2000 holy knights.

The castle utilized the same technology as magic towers. After long years of battle, many low-rank professions and followers of god were taken in by the Evil kingdom.

Luckily this magic tower technology was made for wizards, and only wizards could fully unleash its potential.

 Knights had an attack range of a kilometer, but wizards would at least be able to 10 times that range.

This was also why the Lightning clan only assigned 1 law-defying wizard to guard their castle. With a spirit as an assistant, invaders would be spotted from afar, so all the wizards needed was to protect the magic circles.
