Before departing for the Star Dou Great Forest, Tang Yi deliberately devoted several days to a careful and thorough study of the monograph authored by Su Xiaoyin, titled An Investigation into the Essence of Soul Power and Preliminary Cultivation Experiments.
Upon completing the reading, Tang Yi could not help but marvel at the astonishing pace of technological advancement in Great Xia and the formidable deductive capabilities of its supercomputers.
Utilizing the foundational materials on soul master cultivation provided by Tang Yi, Su Xiaoyin had reconstructed the process of soul power cultivation from level 1 to level 29 in a completely new framework.
According to the treatise: soul power constitutes a form of heaven-and-earth energy, albeit one primarily generated within the human body. Through rigorous deduction, it was determined that the plane in which Blue Star resides is a three-dimensional space, composed of three mutually perpendicular dimensions—typically corresponding to the X, Y, and Z axes in the Cartesian coordinate system.
The Douluo Continent, by contrast, exhibits a rather peculiar nature: it qualifies as a pseudo-four-dimensional space.
In orthodox physics terminology, the fourth dimension in a true four-dimensional space is time.
However, after countless iterations of supercomputer simulations based on the data supplied by Tang Yi, Su Xiaoyin and her team of experts ultimately concluded that the Douluo Continent cannot yet be classified as a complete four-dimensional space.
In a genuine four-dimensional space, phenomena akin to the human dream state would prevail: matter ceases to exist in its conventional form, consciousness flows freely, and gravitational forces vanish entirely.
Su Xiaoyin refrained from expounding at length in the letter, as the subject touched upon the very frontiers of Blue Star physics. Even millions of words would scarcely suffice to elucidate the deeper implications.
In summary, through the collective research efforts of Su Xiaoyin and her colleagues, it was discovered that the additional "half-dimension" unique to the Douluo Continent is none other than soul power itself!
Martial souls are profoundly miraculous entities. When not in use, they reside within the human body, weightless and intangible.
Yet the moment they are summoned and deployed, they unleash torrential power and, in many cases, achieve materialization.
For instance, tool-type martial souls such as the Haotian Hammer manifest with genuine physical presence and substantial mass when called forth.
"Soul power is not an ordinary intangible energy; it represents a special existence that combines aspects of dimensional theory and string theory!"
"The scientific community may designate it as a 'half-dimension.' It is precisely the existence of soul power that renders the Douluo Continent a pseudo-four-dimensional space!"
Having finished the text, Tang Yi experienced a sudden flash of insight: the Douluo Continent is home to divine beings!
Upon reaching level one hundred and ascending to godhood, immortality becomes theoretically attainable!
Above the Douluo Continent exists the Douluo Divine Realm!
Could the Douluo Divine Realm constitute a true four-dimensional space in the strictest sense?
Tang Yi had no definitive answer. Four-dimensional space theory is exceedingly profound, having been established and advanced by luminaries of Blue Star science such as Georg Riemann, Albert Einstein, and Hermann Minkowski.
Should any young person harbor genuine interest in the subject, they would do well to dedicate themselves to rigorous study and scientific endeavor; in time, Blue Star may yet realize technologies once confined to science fiction—spatial wormholes, interstellar traversal, and the like.
"Su Xiaoyin and her team are truly remarkable—immeasurably superior to that so-called 'Grandmaster' Yu Xiaogang!"
Continuing through the treatise, Tang Yi noted that Su Xiaoyin's team had innovatively delineated the optimal cultivation steps for soul power from levels 1 to 29.
These represented the most efficient pathways, maximizing time economy, enhancing meditative efficacy, and fully unlocking human potential.
Most remarkably, the Great Xia scientific team had devised an entirely novel method of soul power transformation:
Analogous to the metallurgical principle of "a hundred forgings to produce refined steel," the practitioner first cultivates soul power rapidly to level 29 without breaking through. Instead, employing the newly formulated soul power cultivation method, the soul power is subjected to extreme compression, forcibly reduced back to level 1.
This cycle is repeated until the human body reaches its physiological limit, at which point the breakthrough to level 30 is finally undertaken!
Tang Yi was profoundly shaken:
"This is truly extraordinary! The fusion of technology and soul power holds boundless potential!"
"According to Su Xiaoyin, after more than one hundred billion simulation iterations conducted by supercomputers and artificial intelligence models, the optimal number of 'compression-rebirth' cycles during the levels 1–29 phase is three. Exceeding three cycles yields sharply diminishing returns, while the physiological burden increases geometrically."
"The Great Xia team has named this revolutionary cultivation system the [Yan Huang Soul Canon]!"
"The levels 1–29 phase constitutes the first volume of the [Yan Huang Soul Canon]!"
The road ahead remains long and arduous. Tang Yi was aware of the immense capabilities of supercomputers and AI models; however, further extrapolation of higher-level optimal cultivation methods would require vast quantities of additional texts, soul power records, combat footage, and related data.
"Notting Academy is, after all, situated in a small city. The collection of books and materials in Notting Junior Soul Master Academy is inherently limited. Reaching level 29 already represents the boundary of what can be deduced from the available resources!"
"Upon returning from the Star Dou Great Forest this time, I must proceed to a larger city!"
Tang Yi resolved to pursue a more ambitious course of action.
Following the cultivation methodology outlined in the [Yan Huang Soul Canon], Tang Yi sat cross-legged in meditation throughout the night. Whenever thirst arose, he simply consumed a bottle of gene-enhancing potion!
Unbeknownst to him, by morning his soul power had advanced another level!
"Thirteenth-rank soul power! The [Yan Huang Soul Canon] truly accelerates cultivation to an astonishing degree!"
"By my calculations, Tang Hao should have already departed the vicinity of Saint Spirit Village to safeguard his precious son, Tang San."
Tang Yi knew that Yu Xiaogang had recently taken Tang San away for the so-called "special training" and was no longer near Notting City. Ever since Tang San awakened twin martial souls, Tang Hao had placed extraordinary importance upon him.
In accordance with the original storyline, Tang Hao would remain by Tang San's side for a considerable period.
"With Tang Hao no longer present near Saint Spirit Village, I can now go in search of my mother!"
Tang Yi thought to himself.
He was fully aware that, on the Douluo Continent, his mother—A Yin—was a hundred-thousand-year soul beast who had taken human form and begun anew. In the end, pursued relentlessly by the Spirit Hall, she had sacrificed herself for Tang Hao.
Consequently, at the site of her original growth remained a hidden treasure buried by Tang Hao: the right leg bone of the hundred-thousand-year Blue Silver Empress.
According to the original narrative, this soul bone was ultimately absorbed by Tang San.
Having traversed into this world, Tang Yi naturally could not permit such a hypocritical individual to claim it.
......…
"Tap, tap!"
Tang Yi soon returned to Saint Spirit Village. He began methodically retracing the events and descriptions from the Douluo Continent novel and animation, seeking the location where Tang Hao had concealed his mother.
After searching for more than ten li beyond the village, Tang Yi finally discovered a secluded and rarely visited mountain grove where soul beasts were scarce.
He slowed his pace and examined the surroundings carefully. Here, the Blue Silver Grass grew unusually lush, subtly undulating in a rhythmic pattern.
Tang Yi calmed his mind and released his own Blue Silver Grass martial soul. The deep-blue blades of grass began to quiver faintly.
Through the resonance between his soul power and martial soul, Tang Yi seemed to perceive something.
It was not sound in the conventional sense, but rather a collective stream of warm, sorrowful, and tenacious life consciousness emanating from every ordinary blade of Blue Silver Grass within several hundred meters.
These common grasses acted as the most loyal sentinels and messengers, silently conveying all information and faint traces of energy toward a single hidden point deep within the forest—a thread of origin energy that shared the same source yet exuded an incomparably noble aura, like a slumbering sun.
Guided by this resonance, Tang Yi parted the vines and, behind a natural stone wall that half-concealed a small mountain hollow, discovered an extremely well-hidden cave entrance.
The interior was dim and damp!
Yet it was suffused with an overwhelmingly rich and undispersable aura of life.
At the center of the cavern grew a single, distinctly extraordinary stalk of "Blue Silver Grass."
