Undead Army!

After reading carefully, the Elven Queen translated the few parts she understood to Pierce.

The contents on those few parts mentioned spending souls to maintain the existence of the deal which was used to call for the help of the undead army.

If this was a battlefield, these undead army would be a perpetual machine. After all, there would always be dead souls on the battlefield.

Coincidentally, large-scale battles often happened on Pierce's side. There were basically thousands and even tens of thousands of creatures.

It seemed like this condition was quite fitting for him.

Pierce checked the use of the scroll with the hint system. Immediately after, a series of golden words appeared in his vision.

[A contract for a powerful undead legion. As you have always been fighting, I suggest that you sign the contract and summon them.]
