The prison is located in the middle of the city with high security around it. While there was only one mech patrolling before, here there are more than three patrolling with four guarding the front. Additionally, Constructs similar to the door guard from before are neatly lined up not far to the right of the entrance in a large courtyard. Large pipes are present there with glass tubes containing blue liquid, similar to the mech's, flowing from a large tank embedded in the ground into transparent elastic tubes connected to each Construct.
Ailord wondered about the blue liquid because from his conversations with Glok and the others, they said there's a few Constructs use a Mana Core formed from Mana Stones after undergoing several modification processes to resemble the Mana Core of living beings. The difference is that their Mana Cores cannot increase in level since they only come from Mana Stones, while the Mana Cores of living beings can because they come from the soul.
