Yu Xiaogang forcibly suppressed his inner elation, putting on a calm and collected expression, and said, "Fine! Since you dare to question my work, I'll naturally play along to the end!"
The crowd below the stage fell silent instantly, all eyes fixed on Qian Renxue, waiting to see what question she would ask.
Su Yuntao quickly tugged at Luo Can's arm and whispered, "Brother Luo, isn't your wife taking too much of a risk? This is a book written by Yu Xiaogang himself; he must know it by heart. What if he loses?"
Luo Can smiled and said confidently, "Don't worry, we won't lose. I have complete confidence in my wife."
Hearing him say that, Su Yuntao didn't know what else to say, and could only turn his head back and nervously watch the movements on the stage.
Qian Renxue casually flipped through the book, stopping at the chapter on the optimal absorption period for Spirit Master's Spirit Ring. She slowly read aloud, "You clearly stated in this book that the absorption limit for Spirit Master's First Spirit Ring is 423 years, and so on, 764 years for the Second Spirit Ring Third Spirit Ring, 1700 years for the third, 3000 to 5000 years for the fourth... until the ninth Spirit Ring Ninth Spirit Ring, at which point Hundred Thousand Year Spirit Ring can be absorbed, right?"
Listening to Qian Renxue read out the contents of his book word for word, Yu Xiaogang felt more confident, and the corners of his mouth couldn't help but turn up slightly. He felt that he had already won most of the debate.
Qian Renxue smiled, then suddenly changed the subject. "Then I'd like to ask Master Yu, is the maximum lifespan of the Spirit Ring they absorb the same for a commoner Spirit Master with no background or resources and a Spirit Master from a powerful sect, a Spirit Master with a top-tier spirit and a Spirit Master with an ordinary spirit?"
This question immediately exposed the most critical flaw in this theory—it is too one-sided and idealistic.
Yu Xiaogang's smile froze instantly. After a long pause, he stammered, "This... naturally can't be compared to other things. What I've written here is just a reference suggestion for ordinary Spirit Master."
"Oh? So it's just a reference." Qian Renxue nodded, not bothering to argue with him, and casually flipped through a few more pages, just landing on the sixth theory, which was the Martial Soul Mimicry Theory of Plant-type Martial Soul that could absorb animal-type Spirit Ring.
"Here you said that weapon-type or Plant-type Martial Soul can absorb beast-type Spirit Ring, and conversely, Beast Martial Soul can also absorb plant-type Spirit Ring, right?" Qian Renxue looked up at him. "Then I'd like to ask Master Yu, have you ever heard of the Martial Soul Origin Theory?"
Yu Xiaogang frowned and thought for a long time, but he still couldn't remember what this so-called Martial Soul Origin Theory was. He could only bite the bullet and ask, "What does this have to do with my theory?"
"It's very important." Qian Renxue smiled, her tone light, but every word was piercing. "I remember, Grandmaster, your martial soul is a mutation of the Blue Lightning Tyrant Dragon, right? As a Martial Soul Mutation, why are your first and second Soul Skill farting? You've studied Martial Soul Theory your whole life, haven't you ever thought about why?"
As soon as these words were spoken, the audience erupted in a burst of barely suppressed laughter.
Everyone knows that Yu Xiaogang's martial soul is Luo Sanpao, and his Soul Skill is to attack by farting. However, no one dares to say it to his face. Now that Qian Renxue has exposed it in public, the scene has instantly become extremely ridiculous.
In fact, Yu Xiaogang's theory of mimicry is indeed extremely useful for ordinary commoner Spirit Master.
However, for the major sects that have already developed their own martial souls to the extreme, the choice of which Spirit Ring to select is based on experience gained over generations. To put it bluntly, his theory is redundant.
Seeing Yu Xiaogang frozen in place, his face flushed red, unable to utter a word for a long time, Qian Renxue pressed her advantage and turned to the second theory in the book—there are no useless martial souls, only useless Spirit Master.
"This is the first time I've ever seen a theory that makes the author criticize himself twice." Qian Renxue shook her head and looked at him, saying, "You keep saying this, claiming to be the number one theorist of Martial Soul Theory, but do you really understand your own martial spirit?"
"How could I not know!" Yu Xiaogang immediately retorted in a shrill voice, "My Luo Sanpao is the first martial soul in history to be separated from the body!"
"Oh? And then?" Qian Renxue asked casually.
"It also has its own intelligence and can act independently without my control!" Yu Xiaogang said stubbornly, trying to save face.
"Then what about its origin? Have you ever figured it out?" Qian Renxue asked again.
Upon hearing this, Yu Xiaogang's face instantly turned extremely ugly.
He knew perfectly well that Luo Sanpao's true nature was that of Blue Lightning Tyrant Dragon that had mutated into Pig Martial Soul. This woman was clearly making a personal attack on him in front of everyone, calling him a piece of trash!
Qian Renxue heard his thoughts and shook her head in disappointment, but she knew in her heart that this was a good opportunity to bring out the most important news of the day.
"It seems you truly haven't encountered the Martial Soul Origin Theory." Qian Renxue looked at him and said, word by word, "Your martial soul is a mutation of the Blue Lightning Tyrant Dragon, its origin is a dragon. It is precisely because of this that you were able to, along with Liu Erlong and Flender, unleash the continent's first Three-in-One Martial Soul Fusion Skill, the Golden Sacred Dragon."
Before Yu Xiaogang could react, Qian Renxue continued, " Master Yu also said in the book that martial souls can be fused with other martial souls. As long as the martial soul attributes are complementary and the soul power frequencies are compatible, Martial Soul Fusion Skill can be formed, right?"
Yu Xiaogang's mind was a complete mess, and he could only nod with a forced smile, "Yes! Our Golden Iron Triangle relied on this principle to complete the Three-in-One Martial Soul Fusion Skill!"
"Is that so?" Qian Renxue scoffed, "Then I'd like to ask Master Yu, is the shared origin of martial souls due to blood ties one of the most crucial conditions for the formation of Martial Soul Fusion Skill? In the entire Douluo Continent, over 70% of Martial Soul Fusion Skill occur between close blood relatives."
She paused, her gaze fixed on Yu Xiaogang: "Or are you simply too afraid to mention this? After all, the core reason why you, Flender, and Liu Erlong's Golden Iron Triangle can unleash the Three-in-One Martial Soul Fusion Skill is that Liu Erlong and you are direct relatives of the same lineage! She is your cousin, you are connected by blood, which is why your spirit compatibility is so high, am I right?"
boom!
These words were like a thunderclap, exploding in the ears of everyone in the square!
Cousin? Romantic relationship? The famous Golden Iron Triangle, the continent-shaking Three-in-One Martial Soul Fusion Skill, actually came about through this kind of relationship?
He not only plagiarized previous theories, but he also dated his own cousin?!
Everyone in the audience was stunned. The scene fell into a deathly silence, followed by a deafening murmur of discussion. The way everyone looked at Yu Xiaogang changed.
"You're talking nonsense! You're slandering me!" Yu Xiaogang completely lost his temper, pointing at Qian Renxue and roaring wildly, "I had no idea that Liu Erlong was my cousin!"
"Don't know?" Qian Renxue raised an eyebrow, her tone full of sarcasm. "You've studied Martial Soul Theory your whole life, and you can't even tell that the Red Dragon Martial Soul is a direct mutation of the Blue Lightning Tyrant Dragon? You don't even understand the core bloodline compatibility condition of Martial Soul Fusion Skill?"
"What about Chrysanthemum and Ghost Douluo's Martial Soul Fusion Skill?! They have no blood relation at all!" Yu Xiaogang roared in rebuttal, as if grasping at the last straw.
Qian Renxue smiled even more calmly and said slowly, "Let me give you an example. The Dai family and the Zhu family of the Star Luo Empire have been intermarrying for generations, and have passed down the Netherworld White Tiger Martial Soul Fusion Technique for hundreds of years. Because the two families have been intermarrying for generations, their bloodlines have long been intertwined, so their Martial Soul compatibility can reach seventy percent."
"As for Chrysanthemum and Ghost Douluo, their martial souls are one plant and one Gui Mei, their auras are positive and negative, naturally complementing each other. In addition, the two have been together for decades and their minds are in sync, which is why they have the Two-Polar Static Domain. This is a one-in-a-million exception and cannot be taken as the general case."
She took a step forward, staring intently at the pale-faced Yu Xiaogang: "How long have you known Liu Erlong and Flender? How deep can your friendship be? Without blood ties, how can your spirit soul compatibility be high enough to unleash Three-in-One Martial Soul Fusion Skill? Who would believe you if you said that?"
Everyone's eyes were fixed on Yu Xiaogang, eager to see his answer.
After all, if you can't answer that, then Yu Xiaogang is just an outsider who hasn't even touched the threshold of Martial Soul Theory, and doesn't deserve to be called a Grandmaster at all.
If you can tell, it's because he pretended not to know anything and was dating his own cousin in order to obtain this Martial Soul Fusion Skill.
That was absolutely a killer move!
Every word Qian Renxue uttered struck Yu Xiaogang's heart like a heavy hammer. He staggered back two steps, his face instantly turning deathly pale.
