"The so-called Ten Core Theories of Martial Souls are derived from this book!"

Starting bid: one gold soul coin!

Upon hearing this, the room fell silent for a moment, then erupted into even louder laughter than before.

"One gold soul coin? Hahahaha! Miss DouDou, are you serious?"

"Your Seven Treasure Glazed Tile School looks down on that theoretical master so much?"

DouDou paused for a moment upon hearing this.

The starting price was set by the auction house owner; she had no idea why.

This also involves the Seven Treasure Glazed Tile School. How should we explain this now?

DouDou thought for a moment and said:

"How could we not value it? This is the highlight of this auction!"

"The price of one gold soul coin is probably because they felt the value of this item was difficult to assess, so they wanted everyone to judge it, and the highest bidder would win!"

No sooner had DouDou finished speaking than another sharp voice rang out, filled with disdain.

"Let everyone judge? What essential points can a level 29 Great Soul Master summarize? Isn't it all just copying from old books and then making his own assumptions?"

These words seemed to set a precedent, and voices of doubt immediately rose from the crowd.

"That's right. Just listen to the theory of martial spirits; when it comes to actually cultivating them, you still have to consider your own family's heritage and the quality of your spirit rings!"

"If you ask me, if his theories are really that amazing, why don't any top academies invite him to be their chief professor? Why doesn't any powerful sect treat him as a guest elder?"

Of course, there are also dissenting voices.

"That's not quite right. I think some of the master's theories, such as the core competitiveness of martial souls, are quite reasonable."

One voice argued.

"That makes sense? Then why is his own martial soul still the same? After all these years, his soul power hasn't even broken through to level 30."

Immediately, someone retorted.

Inside Prince Xuexing's private room.

The prince of the Heavenly Dou Empire also sneered at this moment.

"Hmph, a piece of trash who can't even break through his own martial spirit dares to talk about the essence of cultivation?"

"So-called theories are nothing but empty talk. The upper limit of a Soul Master is largely determined from the moment their Martial Soul awakens."

"Instead of pinning our hopes on these vague theories, it would be more practical to spend more effort hunting for a high-age soul ring or finding a suitable soul bone."

In his view, this so-called theory is nothing more than an excuse for the weak to comfort themselves.

Calling Yu Xiaogang "Master" is just a polite gesture, a way of showing respect.

After all, his surname is Yu!

In the VIP room where Flander was, he nudged Yu Xiaogang next to him with his elbow, a mocking smile on his face.

"Xiao Gang, you're something else! When did you start selling your most treasured possessions behind our backs?"

"This manuscript, I'm afraid it wasn't written by you staying up all night in the Spirit Hall back then, was it?"

Yu Xiaogang's expression at this moment was not as relaxed as Flander's.

This book, "The Essential Manuscript of Martial Soul Cultivation," was indeed compiled from the vast collection of books in the Martial Soul Hall during his early years there. He painstakingly copied, organized, and summarized the information, adding his own insights and deductions.

Each page reflects his countless hours of hard work.

However, on the eve of his departure from Spirit City, this manuscript, along with many of his research materials, should have been ordered to be burned by the Spirit Hall personnel at the time.

How could... how could I be here?

Tang San, standing to the side, keenly sensed the intense fluctuations in his teacher's emotions.

He looked at Yu Xiaogang's slightly pale face and said in a deep voice:

"Teacher, you don't need to do that."

“Your disciple can now earn some gold soul coins. Your hard work should not be passed on in this way.”

As he spoke, Tang San prepared to press the price increase button in the private room.

He didn't want to watch his teacher's intellectual masterpiece be so disrespectfully discussed and valued in this noisy auction.

"Mistress, wait a minute."

Yu Xiaogang raised his hand, stopping Tang San's actions.

Then, he let out a long sigh and looked at the familiar manuscript on the auction stage with a complicated expression.

"No need."

"Most of those theories and deductions are actually imprinted in my mind."

"Back then, the Spirit Hall regarded it as worthless. Now that it can see the light of day again and spread, it may benefit more spirit masters and help them avoid some detours."

He paused, but his tone carried a hint of worry.

"However, my only concern is that some people might only see part of it and take it out of context, or even misinterpret its meaning."

"In theoretical studies, the worst thing is to have a superficial understanding. If you misunderstand and blindly practice, you may go astray, or even... endanger your life."

Upon hearing this, Tang San's heart stirred.

He could understand the teacher's concerns.

Just like his Xuan Tian Bao Lu, if only the internal energy cultivation method of Xuan Tian Gong is passed on, without corresponding supporting techniques, such as controlling cranes and capturing dragons, ghost shadows and illusory traces, or even the Tang Clan's hundred solutions to hidden weapons, then the power of Xuan Tian Gong will be greatly reduced.

Even worse, if a cultivator's intentions are impure or their understanding is flawed, and they force themselves to cultivate, they might indeed, as the teacher said, go astray and become possessed by demons.

"The students admire the teacher's level of attainment."

Tang San completely abandoned the idea of ​​making an offer and said softly.

In the auction hall, sporadic bidding continued.

"One hundred gold soul coins!"

"I'll offer 150 gold soul coins! It wouldn't be bad to buy it and make a joke out of it!"

"Two hundred gold soul coins! Maybe I can really snag a bargain?"
