Killing ground became easy for us. The number was around 30 but we killed them all in ten minutes.
The funny this was that this time I didn't have to go to the battlefield. My three undead skeleton go lines were strong enough to defeat an F-rank monster.
Also by the end of the battle, I have seven new undead slaves, Ground Rat.
The number was 30 but whenever I tried to use my 'Raise Undead' skill the soul of the ground rat persisted and in doing so the soul was destroyed.
But anyway it didn't matter. Now I have three skeleton goblins, seven ground rats and last but not least skeleton Hydra.
I want to make Hydra battle I can't do that in this underground tunnel, if I ordered Hydra to come outside the chilling would collapse and would die under the rubble.
...And I can't let that happen.
That means I have to wait until I go outside of these underground stations.
And I don't when will I go outside.
