Chapter 342: Dream Dimension

Zatiel and the King of the Scientia Kingdom completely immersed themselves in The Ultimate Rune Path's study. They examined every single one of the runic diagrams and magic formulas that John had developed through the years. 

The duo's goal was not to obtain tricks or easy paths to develop John's rune mastery but to enhance his foundation. 

The King was not the only one who improved his runemaster abilities since those of the Neo-Demon were also increasing. 

Zatiel had all the theoretical knowledge about The Ultimate Rune Path, but he still needed a lot of practice to transform it into actual skills.

Although neither of them needed to sleep, their minds still grew tired due to the countless calculations they were performing every minute, so once a week, they rested an hour. 

They continue like that for one and a half months before finishing.
