Although Yu Tianqing has undergone three evolutions, he has grown much taller and more handsome.
But Qian Renxue, disguised as Crown Prince Xue Qinghe, recognized him at a glance.
That face was so unforgettable for her.
"I never expected to run into you here in the library of the Heaven Dou Royal Academy!"
"What's this kid doing here?"
After a moment of hesitation, Qian Renxue slowly moved closer to Yu Tianqing.
At this moment, Yu Tianqing was reading a yellowed ancient book, "On the Origin of Martial Souls".
He read it very carefully, his fingertips lightly tracing the pages, his brow slightly furrowed.
"The Azure Dragon belongs to the Wood element, governs the East, and controls both life and destruction..."
Yu Tianqing murmured to himself:
"If it is fused with the Ice Phoenix Martial Soul, water nourishes wood, so it is theoretically feasible."
"But the dragon and phoenix attributes clash, how can we balance them?"
Yu Tianqing fell into deep thought.
Just then, a gentle male voice came from the side:
"This junior is quite interested in Martial Soul Fusion Techniques?"
Upon hearing this, Yu Tianqing was startled and quickly turned around to look in the direction of the voice.
Upon looking, he saw a blond young man standing beside him.
The man was handsome and refined, and his brocade robe accentuated his tall and straight figure.
"Um?"
"He is... Xue Qinghe?"
After a quick look, Yu Tianqing immediately recognized that the blond man in front of him was none other than Prince Xue Qinghe, the Crown Prince of the Tiandou Empire.
Of course, he was aware of it.
Xue Qinghe was merely a disguise; his true identity beneath that facade was actually Qian Renxue, the young master of the Spirit Hall.
"Greetings, Your Highness!"
Yu Tianqing bowed slightly.
"oh?"
Qian Renxue was taken aback and uttered a soft, hesitant voice:
"You know me?"
Yu Tianqing smiled calmly and explained:
"In Tiandou City, who doesn't know Your Highness, the Crown Prince?"
After Yu Tianqing said that, Qian Renxue nodded slightly and didn't think much of it.
The Crown Prince Xue Qinghe, whom she impersonated, frequently attended grand events.
It's no surprise that they became well-known after being exposed to the public eye.
"This brat only knows that I am the Crown Prince, but he doesn't know that he lied to me back in the Star Dou Great Forest, does he?"
Qian Renxue muttered to herself.
At the same time, Yu Tianqing also began to have doubts:
"She should recognize me, right?"
"She might still be holding a grudge about the time I swindled her out of a bag of gold soul coins back in the Star Dou Great Forest."
"He actually pretended to be nonchalant in front of me."
Yu Tianqing pondered silently.
Several years ago, he had his first encounter with Qian Renxue when he went to the Starry Sky Forest.
At that time, Qian Renxue took a liking to his martial spirit, Xiaoqing, and thought Xiaoqing was extremely cute.
Despite their pursuit, they lost sight of Xiaoqing, but instead encountered Yu Tianqing.
So Qian Renxue inquired about Xiaoqing's whereabouts from Yu Tianqing.
Yu Tianqing had already put Xiaoqing away and asked to exchange information for gold soul coins.
Qian Renxue gave him a bag of gold soul coins, and Yu Tianqing casually pointed out a direction to Qian Renxue.
Qian Renxue hadn't thought much of it at first, figuring that a child wouldn't lie to her.
However, after some further investigation, he realized that he had been deceived by Yu Tianqing.
After a brief silence, Qian Renxue feigned curiosity and asked:
"Little brother, what book are you reading? You seem so engrossed in it."
Yu Tianqing closed the "Theory of the Origin of Martial Souls" he was holding and replied:
"Your Highness the Crown Prince."
"I'm reading 'The Theory of the Origin of Martial Souls'."
Qian Renxue feigned surprise and said with a smile:
"oh?"
"At such a young age, he's already studying martial spirit theory?"
Why are you researching these things?
Yu Tianqing remained calm and explained:
"Who says you can't study these things when you're young?"
"It's always good to learn more."
Qian Renxue was stunned for a moment, and was somewhat speechless after being refuted by Yu Tianqing.
Thinking about how he had been tricked by this little kid and swindled out of a bag of gold soul coins, he felt a burning rage.
After a slight pause, Qian Renxue casually pulled out a book titled "On Soul Ring Adaptation" and said with a smile:
"This book would be quite suitable for you."
As she spoke, Qian Renxue handed the "Soul Ring Adaptation Theory" to Yu Tianqing.
Yu Tianqing glanced at the book title but did not take it.
He wasn't interested in things like spirit ring compatibility.
The reason he sent Dugu Yan to infiltrate the library of the Heaven Dou Royal Academy was to study the Martial Soul Fusion Technique.
As for the "Soul Ring Adaptation Theory," it simply discusses the ratio and age of soul rings at different stages of a soul master's career.
In Yu Tianqing's view, the theory behind this was complete nonsense.
Putting aside everything else, his own soul ring configuration alone is enough to refute it.
"Um?"
Seeing that Yu Tianqing remained unmoved, Qian Renxue frowned slightly and uttered a soft question:
"how?"
"You don't like the book I recommended to you?"
With that, Qian Renxue smiled slightly and then put the book "Theory of Martial Soul Adaptation" back on the bookshelf.
Then she took another book out of the bookshelf.
"Master Yu Xiaogang's 'Ten Core Competencies of Martial Soul'!"
"This is considered a classic in the world of Soul Masters, surely you're interested?"
What surprised Qian Renxue was...
Upon hearing what she said, Yu Tianqing chuckled and said:
"Forget it!"
"Many of the theories here are wrong; they are simply misleading people."
As soon as Yu Tianqing uttered these words, Qian Renxue was slightly surprised.
"Questioning that so-called master?"
Yu Tianqing remained unconvinced and said indifferently:
"how?"
Is his theory necessarily correct?
Qian Renxue became interested and said with a smile:
"Then tell me, where exactly are the master's theories wrong?"
Yu Tianqing smiled slightly and blurted out:
He said that a Soul Master's bottleneck cannot stop the continued improvement of Soul Power.
"If a Soul Master doesn't acquire a Soul Ring, he simply can't level up and advance to the next level."
"However, the accumulation of soul power will continue until a soul ring is obtained. This accumulation can still help a soul master enter a higher level."
Hearing what Yu Tianqing said, Qian Renxue nodded and said:
"That's right."
"This theory is one of the ten core competencies of a master martial spirit."
"how?"
Is there a problem?
Yu Tianqing pursed his lips helplessly and said:
"This theory sounds correct at first glance, but it is missing a premise."
"That means there should be level restrictions."
"Soul power can be accumulated, but there is no limit to how much it can be increased."
"Without this restriction, a level 10 Soul Master could accumulate Soul Power until reaching the Title Douluo level without acquiring a Soul Ring."
"Although he is not a Title Douluo, he has the soul power of a Title Douluo."
"Your Highness, do you think this is reasonable?"
Qian Renxue was stunned, her head buzzing, completely caught off guard by what Yu Tianqing said.
The key point is that, upon careful consideration, what Yu Tianqing said does indeed make sense.
