After using the teleportation gate to verify success, Lynch began the creation of the spell model. At this point, it was relatively easier. After all, the difficult part of a spell model is the calculation and design of the initial parameters. Once these are completed, the rest is just following the pattern.
It only took Lynch a few months to complete the construction of this spell model.
The newly constructed spell model was designed according to his previous plan, able to open a space crack connecting to the underground city and summon undead creatures from it.
Unlike ordinary spell models, the strength of this spell model created by Lynch mainly depends on the strength of the undead creatures he commands.
This is where the tremendous value of adventurers is demonstrated.
