"You picked a weird time to learn that," Rain frowned.
"I didn't pick a weird time. It took me all these years to learn it… although I had a bit more time to practice now since the kids can be watched by Father and Mother as well," Terra explained.
Rain didn't notice that, but Terra was also training hard… it was hard to notice it since she was trying to learn that technique while also using her usual healing skills. Basically, Terra had to control her mana to a point that the mana would follow her will no matter what.
"So, you decide to make the spell activate with your willpower at the moment when it is needed?" Rain asked.
"No, you have to give an order to make the spell activate under certain conditions," Terra explained. "Like, activate when you start to bleed. I just learned it, though, and it only lasts for one hour. I have to improve it."
