The next few days were normal...or what Adrian could call it.
He was spending twelve hours of his days studying the fourth thread.
He has ten days, now four, to finish the first stage which is to evaluate how a person's mana flows under different circumstances.
Mana flow isn't like emotional wavelength that influences the strength of armament. Mana flow works differently and it's not within the control of the person how their mana goes through their body, so all the work needs to be done by the Runesmith.
In a way, the second and the fourth threads are connected. After all, in the second Thread, one must study the mana pores of a being and then attach the threads. These mana pores now would be the entry point and parameters for Adrian to assess his subject's natural mana flow.
