The final best plan

The sun disk was clearly visible.

However, Kant was slightly stunned. He glanced at the three special effects. Each of them could be considered powerful, but they could only affect an area of 5,000 square meters, which was only equivalent to the size of a mansion.

Compared to the Oasis Lookout, which occupied an area of one hectare, the area affected by the sun disk was too small.

Even if it was placed in the middle of the castle, it could only protect one-third of the area.

The area was too small!

This 5,000 square meter is not enough to protect the walls of Drondheim Castle!

Thinking about the Sky Veil of Death, which covered the sky, the area of protection is really too small. When the black fog and dark clouds of the Sky Veil of Death swept over, they have to give up part of the defensive fortifications to protect the area successfully!
