"The concept you're mentioning doesn't really exist in the current Soul Master world," Ye Lingling said with a calm expression.
"This is simply a reasonable hypothesis based on my own research into my martial soul," Ye Yu smiled slightly and spoke slowly.
"My martial soul was originally just a level 1 Blue Silver Grass, a weak innate soul power."
"But perhaps because I often consume medicinal herbs like a hundred-year-old ginseng and hundred-year-old ganoderma,"
"These herbs, with their abundant life source, have affected my Blue Silver Grass martial soul and caused it to evolve!"
Saying this, Ye Yu extended his right hand.
A silver-blue light shone, and a vine-like Blue Silver Vine martial soul, as thick as a vine and translucent like blue crystal, immediately appeared.
"This is—!" Ye Lingling's delicate, cold face displayed shock in her amethyst-like eyes.
Because she could also tell that the Blue Silver Vine martial soul was a mutated form of the Blue Silver Grass martial soul.
"After my martial soul evolved, I began researching Blue Silver Grass martial soul," Ye Yu continued with a smile after dismissing the Blue Silver Vine martial soul.
"I wanted to see if I could find a way to make it evolve further."
"As the weakest plant martial soul, I discovered that Blue Silver Grass is easily influenced by additional soul rings."
"For example, a Soul Master with a Blue Silver Grass martial soul, upon reaching level 10 and absorbing the first soul ring,"
"Will experience a massive transformation of their Blue Silver Grass martial soul, turning from thin grass to thick vines."
"Other martial souls, after absorbing a soul ring, will also undergo changes, but they won't be as significant!"
"Why is that? I think it can be explained by the martial soul's origin."
"What is the martial soul's origin?" Ye Yu asked.
"In my opinion, the martial soul's origin is equivalent to the bloodline of a soul beast!"
"When a soul beast is hunted and turned into a soul ring, the soul beast's bloodline transforms into the corresponding origin and is stored within the soul ring."
"And after a Soul Master absorbs the soul ring, their martial soul will absorb a certain amount of the origin based on the compatibility and strength of the bloodlines between the martial soul and soul ring."
"I believe that the compatibility depends on how closely the martial soul and soul beast match in type and characteristics."
"For instance, a wolf-type martial soul absorbing a wolf-type soul beast's soul ring will have the highest compatibility, and the martial soul will be strengthened."
"If that's not possible, absorbing soul rings from soul beasts with similar traits like tigers, lions, or leopards will also work, and the martial soul will likely become stronger."
"But if a martial soul absorbs a soul ring from a tortoise, ox, or pig, the compatibility is much lower, and the martial soul might even weaken instead."
"The strength of the origin is determined by the bloodline strength of the soul beast the martial soul belongs to and the soul beast from which the soul ring originates."
"In my opinion, the weaker the bloodline of the martial soul's soul beast, the more origin it will absorb from a stronger soul beast of the same type, and the change will be more significant!"
"Conversely, if the martial soul's soul beast has a strong bloodline, such as the Blue Lightning Tyrannosaurus martial soul absorbing a sub-dragon soul beast's soul ring, the martial soul will absorb almost no origin and won't change!"
Ye Yu spoke with a smile, explaining the laws of martial soul transformation through the concept of soul ring origin.
According to this theory, any Beast Martial Soul Soul Master can evolve their martial soul by finding a high-compatibility soul beast with a high bloodline level, hunting it, and absorbing its soul ring to continuously absorb the origin and achieve evolution!
"This theory, I call it the Soul Ring Origin Completion Evolution Theory!" Ye Yu concluded with a smile.
After hearing Ye Yu's explanation, Ye Lingling's beautiful face displayed admiration as her purple eyes reflected awe.
"Your theory really makes sense!"
"It can completely explain why powerful martial souls often show little change after absorbing a soul ring,"
"While weaker martial souls undergo significant changes after absorbing a soul ring!"
"Exactly!" Ye Yu nodded slightly.
"However, this theory still has some issues."
"Because many Soul Masters, after absorbing a soul ring, their martial souls don't really change,"
"In other words, their martial soul doesn't truly absorb the soul beast's origin stored in the soul ring and fuse with it to evolve, it's only superficial."
"I believe this is most likely due to insufficient compatibility."
"Only with enough compatibility can a martial soul truly absorb and merge with the soul ring's origin to cause a transformation."
"And Blue Silver Grass, being the weakest plant martial soul, has the greatest characteristic of being extremely resilient, almost like: 'wildfire can't burn it, and the spring breeze makes it grow again!'"
"Life attribute plant soul beasts should have the highest compatibility with my Blue Silver Grass martial soul."
"That's why I plan to choose a life attribute plant soul beast as the future soul ring for my Blue Silver Grass martial soul."
"But for now, I haven't started absorbing soul rings yet, and I don't know if my idea is correct," Ye Yu sighed.
Upon hearing this, Ye Lingling's exquisite and cold face grew serious as her beautiful purple eyes gleamed with encouragement.
"Ye Yu, I believe in you, you can definitely succeed!"
"With your own strength, you will change the weakness of your martial soul and make it evolve."
"Finding a theoretically feasible path already shows how amazing you are!"
As she spoke, her thoughts seemed to wander, and Ye Lingling bit her lip. Beneath her long blue hair, her purple gem-like eyes became slightly red.
As a member of the Nine Heart Sea Tang clan, she had always been seeking a way to solve the fatal flaw of their Nine Heart Sea Tang martial soul.
She had always loved reading, perhaps hoping to find a way to fix the flaw of their martial soul.
But unfortunately, she had never found a solution.
Not even a theoretically viable method!
Therefore, she deeply admired Ye Yu and looked up to him.
She so wished that she could be like Ye Yu!
In the following days, their relationship progressed rapidly, with Ye Yu purposefully drawing closer and Ye Lingling having a favorable impression of him.
Soon, they became friends.
To deepen their connection, Ye Yu also took the opportunity to reveal his background, discarding the self-reliant orphan persona.
Upon hearing that Ye Yu had lost his parents at a young age, Ye Lingling was immediately filled with sympathy.
She had always thought that losing her grandmother due to her Nine Heart Sea Tang martial soul was the greatest misfortune, but Ye Yu's loss seemed even greater.
He had lost his parents when he was so young!
In that atmosphere, Ye Lingling also spoke about her own past, sadness, and troubles.
She hoped to find a way to compensate for the flaws of the Nine Heart Sea Tang martial soul so that her children would not face the same pain and sorrow she had.
Ye Yu also felt deeply for her.
Though he had approached Ye Lingling intentionally, his heart was genuine.
Hearing her experience, how could he not feel sympathy?
Unfortunately, Ye Yu couldn't think of a way to resolve the flaw of the Nine Heart Sea Tang martial soul either.
Perhaps the fairy herbs in the Ice Fire Yin-Yang Eyes could help the Nine Heart Sea Tang martial soul evolve and fix its flaw.
If that were the case, then he should try to get closer to Dugu Yan!
One day, after they finished reading at the library, Ye Yu suddenly smiled and said to Ye Lingling as they exited.
"Lingling, may I make a painting for you?"
