Learning
"Anyway, that's how it is. I will be teaching the rest of the knowledge within one hour and you are free to ask me any questions." Hel extended her hand as if asking Theo to come with her.
Theo nodded furiously. He promised to get better and learn everything from her.
After agreeing with Hel, Theo's training finally started. As Hel said from the start, Theo was practicing all his five senses.
Of course, Hel's main objective was to master the "sight" first before reaching Supreme Rank. Hence, the training became even more challenging when it came to "sight."
He literally needed to endure Hel's killing intent coupled with the Magic Power. Within an hour, Theo had died more than a thousand times. If they were in the real world, Theo might have actually died.
Luckily, Theo's determination was strong and his mind had become sharper after solving his last doubt against his family.
