William realized that he didn't need to sleep the day after he transmigrated.
His powerful mental strength made it very difficult for him to feel any mental fatigue. Even if he read historical documents intensively for a few days, the mental burden he felt was only to yawn a few times.
The only time he felt a little tired was when he was testing the limits of his magic power. After renovating Arcana University's underground training range dozens of times with all kinds of magic, he finally felt a little sleepy.
However, all it took was a few minutes of meditation to shrug it off.
Later on, he learned from Vincent and the others that after one's mental strength reached the Master level, the requirement for sleep could be replaced by meditation.
Before he transmigrated, William was a night owl. It was only when his middle-aged body gradually couldn't take it that he gradually changed his sleep schedule. Now that he had such talent, why waste it?
