Miracle

He left the combat ring, leaving the medics enough space to tend to Jeffrey's wounds. On the other hand, Michael was unscathed.

His energy consumption had been quite high, and he had been under tremendous stress, but he was physically uninjured. 

Michael consumed an energy pill to replenish his used-up origin energy before he sat down on a bench to rest.

'It was not perfect, but I did a decent job, that's for sure.'

He was glad that he didn't rush to improve his War Rune in the last few weeks. 

His opponent's War Rune had a higher degree of refinement but he didn't win. 

Why was that the case?

There were multiple reasons, but the most important was that Michael had focused on other things in the past few weeks.

He diligently accumulated combat experience, fixed some flaws, finished his Berserker Physique's first stage, and focused on his Soultraits' control and utility.
