Before he knew it, Lawrend's children became Heaven Mages one by one. It was inevitable as they were all very talented, to begin with.
Sanaka and the others were surprised but didn't think much of it at first.
But Lawrend's children became Heaven Mages like worms appearing after a light rain. It was unexpected that they all became Heaven Mages successively.
"Good."
That was all Lawrend had to say to his children. He was already expecting it, so it was never a surprise for him. It was more like a matter of patience.
Each of them developed their own magic. These magics were combination spells that were non-existent outside of Lawrend's children. He specifically taught them his magic spells, so they would grow up like this.
Lawrend then spent another two years understanding the whole magic branching of the demon world. He learned more than he could ever hope for. The elusive level of Divine Mage became visible in his sight.
