157 Pandemonium's Requiem

[Michael: What is the most cost-efficient external means to improve your subjects' refinement degree and Tier?]

Michael knew a few external means to accelerate a subject's growth and boost his refinement degree, but most were too expensive for someone like Michael to afford.

The external means were consumables, which were priced much higher than the money Michael had in his bank account most of the time.

That was also why he had sent a short message to Alice before he closed the messenger. 

Alice might not be able to help him, but he could at least try asking her for guidance. 

Once the message was sent out, Michael closed the messenger. He arrived in the small room that was set up especially for Harry Baren to conduct his research on Soul Power and Soultraits.

Other than the Limit Breaker course, Michael had three more lessons to attend. He had applied for the History of the Origin Expanse, Memory Lane, and Soul Power theory.
