Six Months
Everyone began their training even more seriously. There wasn't a single complaint anymore as the girls couldn't help but imagine what kind of training Kai had to endure.
In the end, one of them often called Kai to check his condition and asked him about his training.
They soon found out Kai had indeed run from Emulda Kalan to India while fighting monsters and improving his skills.
After that, they realized Kai had been swimming in the longest river near them. He kept fighting and improving his magic.
It didn't stop there. Kai's training became even more extreme as he progressed like climbing the cliff without his magic, flying in the sky and fighting all types of birds, and many others.
When the girls saw what happened to him, they just didn't feel like losing and began practicing like crazy.
