Night fell swiftly.
By this time, Reiger had already returned to his residence, where he sat in the hall, leafing through the ancient tome that documented the Mechanical Puppet Technique.
The contents of this ancient book were extensive; it was a thick volume, filled not just with text but also with illustrations. Even for Reiger, finishing it in one sitting was not feasible.
Thus, Reiger took the tome home with him, promising Xiao Tie that once he had finished reading the book, he would repair Yoriichi Model Zero for him.
The task was not difficult.
Once he had committed Yoriichi Model Zero's blueprints to memory, Reiger could use Construct-type Magic to directly create a new Yoriichi Model Zero. At that point, refurbishing an old model would be a trivial matter.
