The next day.
Grey and his grandfather had been practicing all through the previous day, given their cultivation stages, they didn't have any reasons to stop, especially with Grey almost close to achieving the inscription method.
Martha and her mother didn't have anything important to do, so the duo stayed to watch them.
Grey didn't know how many times he had tried it, or how many ways he had tried to manipulate the elemental essence around him. But he didn't stop, he tried after each failed attempt, he didn't show any signs of frustration even when things weren't going the way he wanted, he still didn't give up, he continued trying different methods to manipulate the elemental essence around him. During the process, he noticed that his control over each of his attacks were on the rise. He hasn't even tried to make any normal elemental attacks, but he could already sense the difference in his body.
