"Invincible" Theory

"Do you know the author of this book?"

Zhang Ming answered, "Yu Xiaogang, known as Grandmaster. He's unmatched in martial soul research, and is called Invincible in Theory."

Quan Yi was a little astonished. If he was called Invincible in Theory, why had Quan Yi never seen his books in the family's collection all these years?

And the book had even been placed in such a remote corner.

"If he's called Invincible in Theory, then what's wrong with me planning to buy his book?" Quan Yi asked in confusion.

Zhang Ming chuckled twice. "Heh, heh. Invincible in Theory isn't meant as praise. It means that, up until now, no one has been able to prove whether his theories are actually correct or not."

"If no one can prove a theory wrong, doesn't that make it an 'invincible' theory?"

Quan Yi understood. So that was it.

Indeed, with something like the Martial Soul Mimicry Theory, no one had been able to prove it to this day, and no one would risk their life to absorb a dangerous Soul Ring for the sake of testing it.

At that moment, a question suddenly arose in Quan Yi's mind.

As a member of the Blue Lightning Tyrant Dragon Clan, why had he not conducted experiments?

Why had this "joking title," Invincible in Theory, fallen on this man?

Quan Yi asked, "Yu Xiaogang—is he not a member of the Blue Lightning Tyrant Dragon Clan?"

When Zhang Ming heard the words Blue Lightning Tyrant Dragon, he suddenly became nervous.

"Shh, keep your voice down. Don't let anyone hear you." Then he leaned his upper body slightly forward, moved closer to Quan Yi, and said quietly:

"I heard this Grandmaster left his clan in his early years because his talent wasn't good, joined Spirit Hall, and then left Spirit Hall too. That's all I know."

"Senior, you're so knowledgeable!"

Hearing praise from his junior, Zhang Ming became a little embarrassed and raised his head to scratch the back of his head.

"I only heard it from the Library curator. It's nothing impressive. I'm telling you this just to remind you that it's fine to read these theories, but you absolutely must not try them."

Zhang Ming was a good person. Otherwise, he would not have gone out of his way to warn Quan Yi. But Zhang Ming did not understand the value of this book.

"Thank you for the warning, but I still want to buy a copy. If there are any other works by this person, I want those too," Quan Yi said, still sticking to his opinion.

Seeing that Quan Yi was so insistent, Zhang Ming did not say anything more.

"All right, then. I'll ask the curator. When you return the book next week, I'll tell you."

Quan Yi hurriedly thanked him. Then, after filling out the form, he picked up the book and walked out of the Library.

After leaving the Library, Quan Yi placed the book into the Blazing Sun Heart, but his expression suddenly turned solemn. He murmured softly, "Spirit Hall."

Quan Yi had not expected that the one behind this was not the Blue Lightning Tyrant Dragon Clan, but Spirit Hall.

In that case, this data should have been collected by Spirit Hall.

Spirit Hall controlled information on the vast majority of spirit masters across Douluo Continent, and that information was an extremely precious asset.

But Spirit Hall did not seem to understand the value of big data analysis yet.

Because they had not verified this theory. That meant Spirit Hall itself did not approve of Yu Xiaogang's theory either.

From this, it could be seen that the entire Spirit Master World's research into the essence of martial souls was not deep. All attention was focused on increasing strength.

But this was a kind of laziness—intellectual laziness.

Human thought was slowly becoming rigid, starting to treat so-called experience as absolute truth while ruthlessly criticizing new ideas.

Quan Yi warned himself that he absolutely could not fall into intellectual laziness. He had to keep thinking and doubting forever.

Although this world was a strange and novel otherworld, its essence was that of an incomparably backward world.

This backwardness referred to its thinking.

If he was not careful, Quan Yi's soul would be polluted by the "old" of this world.

Therefore, Quan Yi had to keep thinking and doubting. Only in this way could he preserve the "newness" of his soul.

After leaving the Library, it was also time to train.

Quan Yi still went to the same Training Ground as before, and there still was not a single person in sight.

Quan Yi's noon training was anaerobic exercise, mainly intended to increase his body's explosive power.

The training items were Burpees plus Pull-ups.

Burpees combined a series of movements including squats, push-ups, abdominal tuck-ins, and squat jumps, allowing him to raise his heart rate in a short time and activate the muscles throughout his entire body.

With Pull-ups added on top, this combination was exhausting just to think about.

This was also the training method Quan Yi had chosen by combining it with the experience from his previous life.

Quan Yi's training would be carried out in sets.

After forty Burpees, he immediately performed forty Pull-ups. He rested for one minute in between, then moved on to the next set.

He did twenty sets in total.

Quan Yi's movements were extremely standard. Moreover, he did not deliberately pursue speed, instead ensuring that every movement kept its form.

His body maintained a sense of tension the entire time. When doing Pull-ups, he rose slowly and lowered himself slowly, which put even greater pressure on his arms.

The temperature kept rising, but the sweltering weather did not affect Quan Yi in the slightest.

Even at the very end, Quan Yi maintained perfect form throughout, relying on his powerful will to complete his midday training.

After exercising, Quan Yi did not forget to stretch either.

This kind of extreme workout was something an ordinary person might not be able to endure after experiencing it even once. But Quan Yi did it three times every day.

What kind of willpower was that?

Quan Yi's white short-sleeve shirt was already soaked through with sweat. Because it was noon and he was afraid someone might come by, he had not taken it off.

After exercise came the happiest time of all—mealtime.

Quan Yi dragged his heavy body toward the Dining Hall.

The moment he entered the Dining Hall, Quan Yi smelled the aroma of food.

Starving, Quan Yi headed straight for the second floor, his mind filled with nothing but eating.

At that moment, the surrounding students all noticed Quan Yi.

It was no wonder. Quan Yi's white short-sleeve shirt had been soaked by sweat and had become somewhat transparent.

His solid pecs and broad shoulders were fully on display.

They drew the gazes of every student present.

Some shy young girls blushed and turned their heads away, while some bolder girls stared fixedly at Quan Yi's body.

When the boys in the Dining Hall saw Quan Yi's muscles, their hearts grew solemn. Faced with such an overwhelming gap, all they felt was admiration.

Quan Yi was completely unaware of this. He went straight up to the second floor and disappeared from everyone's sight.

The second floor was the same as in the morning: fewer people, and quiet.

Quan Yi immediately filled two large plates with food and walked to a secluded corner. Just as he was about to take the jerky out from his chest, he heard an ear-piercing voice.

"Where did this bumpkin come from? How disgusting."

Quan Yi immediately looked in the direction the voice had come from, only to see a boy with an unruly look in his eyes staring at him.

"What are you looking at? I'm talking about you. Can you go downstairs to eat? You're covered in stinking sweat. Don't ruin our meal, all right?"

The boy was not very old, but he should have been an upper-year student. He was dressed in expensive clothes, but the disgusted expression on his face completely lowered Quan Yi's impression of him.

Quan Yi was somewhat speechless, wondering if the feng shui of this Dining Hall was bad.

He had only come here twice, yet trouble kept happening one after another. Couldn't they just let him eat a meal in peace?
