Doing the calculations in a magic formula was not a very difficult task. Even if a mage was only grade-1, they would still be able to rely on alchemical equipment to calculate extremely complicated formulae. For a mage like Saleen who possessed powerful mental power, he could simply do the calculations in his head.
If Saleen had possessed dozens of students, he could have simply delegated this job to his students and asked them to calculate the different parts of the magic formula before piecing everything together.
Saleen now knew that it was so imperative for a mage to have a large number of followers. However, right now, he could only rely on himself to calculate the tens of thousands of formulas before restoring them into the lines and patterns of the magic array. As Saleen calculated through the night, he went in and out of the necklace repeatedly and meditated many times, causing his body to become extremely exhausted.
