Kai tried to understand the mechanism of formation instead of observing the formation.
He knew it was easier to find out about the fake lines after he understood the entire formation.
With the help of his learning talent and parallel thinking ability, Kai began to brainstorm.
His brain worked like a supercomputer, and in an hour, he understood the first formation.
With enough confidence, Kai continued his work. He didn't have enough time to steal the fragment since the worship ceremony could end at any time and the guardians could arrive.
After three hours of brainstorming, Kai understood the workings of the entire formation.
'Now, I should start breaking the formation; I don't have enough time.'
With his understanding of the formation, Kai ignored the fake lines and began to find the weakness of the formation.
Every formation has some weak point, and by finding that point, a formation can be used against the user.
