Explosion

The legend of Mana Calamity is quite mysterious and one couldn't really tell what kind of disaster will happen with it.

However, as far as they know, it would result in massive destruction of land or surroundings… It would also create strange phenomena that couldn't be explained just like the Illusion of the Venarian Town.

Lewis and the other Mech Knights were unsure how Wallace is planning to trigger the calamity but they can sense the strange vortex of mana happening…

"We have to retreat now!"

Their mission to freeze the fleet and cast Mana Spell to try to invade their internal structure can be considered a success already.

If they try to force themselves to further damage the gigantic spaceships in front of them, they would be in extreme danger.

Even right now, they can feel that the Imperial Flagship is still exuding a threatening aura even after being covered by the black ice.

"We haven't destroyed all their sensor craft yet!"
