Best Instructor

Michael was doing perfectly fine. 

His biggest worry was to keep his subjects entertained, to refine his body, mind, and War Rune, and to study the techniques Immortal Knight was teaching his students. After ten days of hard work, 15 Starless Summons advanced to 1-Star Blessed Knights. They were promoted automatically, which accelerated their natural talent to absorb energy, their comprehension of the body refinement technique Siegfried taught them, and how to harness the Holy Power within their Holy Sea.

Michael learned a lot too. His biggest gain was that he finally learned a Standard Martial Arts technique. It was an Inferior version to the Sacred Sword style the Immortal Knight was teaching his students, but that was something Michael had expected. He didn't have any Holy Power so he had to use an altered version of the Immortal Knight's technique to substitute Holy Power with Origin Energy.
