On the Relationship Between Physical Strength and Magic Power

Erza immediately asked curiously, "Cain, doesn't a Mage only need powerful magic power? Why do you still train your body so hard?"

Cain had long since considered Erza's question. "I believe that for a powerful Mage, the body and magic power complement each other."

"Erza, do you know that after awakening magic or learning magic, a Mage's physical abilities become far better than those of ordinary people?"

After thinking about it, Erza realized that was indeed true. Ever since awakening her magic, her strength, recovery ability, and everything else had improved greatly compared to before.

Erza guessed, "Could it be that the magic power inside our bodies strengthens us?"

"That's right." Cain nodded. "Everyone in this world possesses magic power. The only difference is how much they have."

"Ordinary people have relatively little magic power, so the enhancement is not obvious. Mages have more magic power, so the enhancement is much more apparent. The stronger the Mage, the stronger their body will be, even if they have never trained it."

Cain's words only made Erza more confused. Since stronger magic power meant a stronger body, why train so arduously? Wouldn't it be enough to work hard at increasing one's magic power?

As though he knew what Erza was thinking, Cain continued.

"Erza, do you know that excessively vast magic power can also become a burden?"

Erza could not understand. How could magic power become a burden?

"Our bodies are like buckets, while magic power is the water inside them. If the water exceeds the bucket's capacity, the excess water will simply spill out."

"And if the magic power in our bodies exceeds the limit our bodies can endure, what do you think will happen?"

Cain quietly watched Erza.

At first, Erza thought the excess magic power would flow away like water, but she immediately realized that a body was not really a bucket. It could not simply open a hole and release the magic power inside.

Release magic power? Magic? Erza's eyes suddenly lit up. "What if we release the excess magic power through magic?"

Cain shook his head. "The prerequisite for casting magic is being able to control the magic power in your body. But that excessive magic power is like runaway cattle and sheep. It cannot be controlled at all."

Unable to ease it by releasing magic power, Erza fell back into thought. Cain had said excessive magic power was like runaway cattle and sheep. Once cattle and sheep lost control, they would charge around wildly.

If they were locked inside a fence, they would break the fence apart.

"I understand!" Erza suddenly stood up and said excitedly, "A balloon. It's like a balloon. Every balloon can only hold a fixed amount of air. Once it exceeds the amount it can withstand, it will explode."

Cain had not expected Erza to use a balloon as an analogy. It really was more vivid and fitting than his bucket comparison.

"That's right. Once magic power exceeds the limit the body can withstand, it becomes a burden. It places pressure on the body and causes all kinds of illnesses."

Cain continued, "Training the body raises the upper limit of how much magic power it can endure."

Erza immediately added, "Just like replacing it with a balloon made of better material."

Cain looked at Erza with some surprise, then smiled and nodded. "That's right. I didn't expect you to understand it so quickly, Erza."

Then he remembered that Erza was the Fairy Queen from the original story. Aside from bringing heaps of luggage whenever she traveled and not caring much about the distinction between men and women, she surpassed the main cast in nearly every other respect.

Especially in battle, where she could keenly seize an opponent's weakness and deliver a fatal blow.

If everyone encountered ads like "Are you a real person?", there was no need to pay attention to them. Just close them, and never scan codes or send text messages!

So what had made him underestimate the future Fairy Queen? It seemed that awakening memories of his past life had made him feel somewhat superior.

Erza was in an excellent mood after Cain's praise and had no idea that Cain was currently reflecting on himself inwardly.

In truth, Cain trained his body largely because of the influence of novels from his past life. In those fantasy and immortal cultivation novels, which protagonist was not built like solid steel?

On top of that, he had a dream of building a harem, so he had to work even harder. If he could not even handle one wife, what right did he have to talk about having a harem?

Of course, he could never say something like that aloud. It was enough for him to know.

After washing up and eating breakfast, the two headed to the guild together.

Upon arriving at the guild, Erza was pulled aside by Cana, and the two whispered to each other nearby.

Cain did not see Gray anywhere. He was probably out taking a job. When he saw Makarov beckoning to him, he walked over and asked, "What is it, Master?"

Makarov glanced at Erza in the distance and asked with concern, "How is Erza's eye?"

"She just had surgery at Granny Porlyusica's place yesterday. She just needs to rest and recover properly from here on."

Cain roughly explained what had happened. Hearing that everything was fine, Makarov's worried heart finally settled, and he resumed enjoying his delicious beer.

He had been so worried about Erza that even his beer had tasted bland.

Cain was not surprised by Makarov's concern, because in the original story, Makarov had been the one to take Erza to Porlyusica for treatment.

To Makarov, the guild was his home, and its members were like his children.

Cain looked around and did not see Laxus, so he could not help asking, "Master, did Laxus go out on another job?"

At the mention of Laxus, Makarov could not help sighing. "Yes, that kid..."

He glanced at Cain, as though he wanted to say something, but could not bring himself to say it.

Cain understood what Makarov meant and said with a smile, "Don't worry, Master. Laxus is just going through his rebellious phase."

Ever since Ivan had been expelled from the guild, Cain and Laxus had gradually grown distant. Laxus had become increasingly withdrawn, and Cain was the only one in the guild he could still talk to.

Makarov wanted Cain to spend more time with Laxus and talk to him, so that he would not be so isolated, but he found it hard to say such a thing aloud.

Fortunately, Cain understood immediately, which comforted him greatly. If only Laxus could be as sensible as Cain.

After confirming that Laxus was not around, Cain headed toward the library. The Gravity Room research was only missing the final step.

The reason he had looked for Laxus was that his hands were itching for a fight. Perhaps after spending so much time in Fairy Tail, Cain had also caught the guild's battle-hungry habit.

Unfortunately, only Laxus in the guild was currently a match for him. Erza had just escaped the Tower of Heaven, her body had yet to fully recover, and the equipment in her Requip Space was nearly nonexistent.

Although Erza could not be called weak at this point, she was still lacking somewhat.

As for Macao and Wakaba, there was no need to mention them. They were certainly good at drinking, but in a spar, they were only a little stronger than Gray was now.

As for the Master and Gildarts, Cain was not a masochist. Unable to find anyone to spar with, he could only go do some research.
