Moreover, through reading, Wu Yu finally understood the essence of advancing to a higher level.

In fact, whether it's magic or battle aura, the total amount that each person can store is fixed. Advancing in rank will not increase a person's energy storage limit; it will only enhance the quality of the energy stored in your body.

Just like the energy provided by one kilogram of charcoal and one kilogram of antimatter are worlds apart.

Because the energy stored in the body is vastly different from the energy in the outside world, the idea of ​​recovering battle aura and magic power while fighting is complete nonsense. Professionals in this world could actually be overwhelmed by sheer numbers.

However, if he fails to defeat his opponent in one move, he will be defeated by his opponent, so endurance is meaningless to Wu Yu.

"Hoo." Wu Yu exhaled a breath of stale air, and then ended his meditation.

Wu Yu took out the book "Detailed Explanation of Magic Tricks" from his storage ring and then quickly flipped through it.

After reading the first few pages, Wu Yu realized that the magic in this world was very different from the magic he had come to understand.

These magicians establish magical circuits in their brains, but these circuits are not magic slots. In other words, activating these circuits does not allow you to unleash magic. Their true function is to process your magic power, causing a change in its properties.

A low-level mage can perform a change of nature once, a mid-level mage twice, and a high-level mage three times, with the highest corresponding to sixth-order magic. Above that are forbidden spells, which require chanting several long phrases.

Both first-tier and second-tier magic only require one change in nature; the only difference lies in the magnitude of their power.

Moreover, the combination of properties changes is not arbitrary; the creation of each spell is the result of the magician's efforts.

For example, the Fireball spell that Wu Yu thought was very simple turned out to be a third-tier spell that required two property changes: "burning" and "compression".

Wu Yu doesn't even have a single magic circuit in his mind right now, which is why his teacher said he can't even cast a single spell.

Looking at the magic circle depicted in the book, Wu Yu felt that he needed to carve a magic circuit for himself.
