"Holy crap..."
As he grasped the solution devised by that woman from the Yun Clan, Ling Xiao couldn't help but mutter a curse under his breath.
He could well imagine that at this very moment, many of the students in the class must be completely bewildered—some were likely even feeling their heads spin.
Even with his relatively mature mindset, he had only just managed to grasp the general concept of this Single-Attribute Fusion Stream. The solution and the process of discovery were far too arduous.
Compared to the previous two fusion streams, the difficulty of the third stage's development and the problems it aimed to solve had risen exponentially.
Anyone capable of finding a solution to such a situation could absolutely be called a Grandmaster of Martial Souls. If nothing else, he could guess that if this method truly solved the defects of the Yun Clan's Martial Soul.
It essentially meant the defects of all Ordinary Martial Souls in the Soul Master world were solved as well. The scope of its impact was incomparable to the previous two fusion streams.
A Grandmaster of Martial Souls capable of solving such a significant cultivation problem in the Soul Master world was, in a sense, far more precious and deserving of respect than a Titled Douluo.
At this moment, the number of people in the classroom who could grasp the general gist of the Single-Attribute Fusion Stream like Ling Xiao was few and far into between.
Beside him, Xu Yu's brow was furrowed deeply as he repeatedly pondered the teacher's words, terrified that he wouldn't learn the lesson and would fail to live up to his parents' expectations.
The delicate faces of Hu Liena and Tuoba Yu'er had lost their usual playfulness and serenity. They frowned from time to time, eyes filled with confusion, feeling as if their heads were buzzing. Most of the others looked much the same.
Xu Lin understood the students' state of mind perfectly; she found it quite normal.
Every time she reached this section, the students reacted this way. In fact, she didn't even expect six-year-olds to get it—even when she had first learned this content, she hadn't understood it immediately.
Seeing that some students had already given up while others were still contemplating, Xu Lin said softly, "Teacher has just finished giving a general introduction to the Single-Attribute Fusion Stream deduced by that Yun Clan woman to solve her clan's Martial Soul defects. This section is indeed quite complex and dry."
"It is perfectly normal that you don't understand it right now. There is no rush to grasp the Single-Attribute Fusion Stream all at once; I will go over it again in later lessons."
"According to records, once that Yun Clan woman created this method—of which she was reasonably certain—she immediately told her father, the Clan Leader of the Yun Clan at the time."
"Although the method she proposed was based on deduction, upon careful consideration, it was well-founded and logical. After her father discussed it with the clan elders, they finally agreed to her method."
"They decided to select a group of clan disciples who had only recently awakened their Martial Souls to cultivate according to her Single-Attribute Fusion Stream, with her providing full guidance throughout the process."
On the podium, Xu Lin did not hide the admiration in her eyes.
She spoke with a hint of excitement, "The first element the Yun Clan chose was the Lightning attribute. After all, among the many elemental attributes, the attack power of Lightning is exceptionally outstanding, complementing the sharpness of a sword perfectly."
"Roughly forty years passed. Among the group of Yun Clan members practicing the Single-Attribute Fusion Stream, one finally reached the realm of Soul Saint. Subsequently, among the children he sired, just as the woman had predicted forty years prior..."
"The Martial Soul that awakened was indeed a sword-type possessing powerful lightning energy. It could be classified as a High-grade Martial Soul and possessed a high level of Innate Soul Power."
"It was named the Azure Light Sword. When the child began cultivating and absorbed their first Soul Ring, it completely verified the woman's theory: the efficiency of the Soul Ring's absorption was not inferior to any other High-grade Martial Soul."
"By then, that woman was already in her seventies. It seemed that solving the clan's Martial Soul defect had consumed too much of her mental energy; her body had become quite frail several years prior."
"The successful result seemed to allow her to finally let go of her worries. After discussing matters in a secret room for a time with the current Clan Leader—one of her cousins—she passed away."
At this point, Xu Lin's tone couldn't help but turn somber, lamenting the passing of such an extraordinary woman.
"However, on the day after the Azure Light Sword Martial Soul was successfully forged and that woman passed away, the current Clan Leader of the Yun Clan announced a shocking piece of news."
"The Yun Clan would leave their ancestral home and choose a hidden location to exist as a Reclusive Clan. At that time, the Yun Clan's strength was not considered great in the Soul Master world, so their seclusion didn't cause much of a stir."
"However, roughly six hundred years later, the Yun Clan ended their seclusion and reappeared. Their emergence instantly shocked the entire Soul Master world."
"In the eyes of outsiders, the Yun Clan before their seclusion was merely a medium-sized clan whose highest cultivation was only at the Soul Saint level."
"Moreover, due to the defects of Ordinary Tool Martial Souls, their combat power at the same level was inferior to other Soul Masters. But after this reappearance, people discovered that the Yun Clan's Martial Souls had undergone a world-shaking transformation."
"The Yun Clan alone possessed six types of High-grade sword-type Martial Souls, divided into five lineages: Fire, Ice, Wind, Lightning, and Earth. The Lightning Sword lineage alone contained two types."
"Although the number of descendants for each type wasn't large, it was still a terrifying reality. Furthermore, they possessed two powerhouses at the Soul Douluo level."
"Now, while one clan inheriting five major sword lineages sounds shocking, compared to other Soul Master clans that pass down a single type of High-grade Martial Soul, it didn't necessarily offer a greater advantage."
"After all, if a clan inherits multiple types of Martial Souls, the disciples' focus becomes scattered. The number of people in each lineage is small, and the research and refinement of their own Martial Souls would naturally be slower compared to other clans."
"This was especially true for the Yun Clan with six types of High-grade Martial Souls; it would surely drag down the speed of their progress."
Xu Lin became somewhat excited as she continued, "However, the Yun Clan clearly had a plan. When they reappeared, their strength and the transformation of their Martial Souls stunned the great clans of the Soul Master world, including the Spirit Hall of that era."
"Everyone was extremely curious about how the Yun Clan had solved the defects of Ordinary Tool Martial Souls. The Yun Clan revealed everything about the past and went public with the Single-Attribute Fusion Stream."
"This shook the Soul Master world once again, and their fame spread far and wide."
"Not only that, taking advantage of the moment when they were the center of attention, the Yun Clan announced another piece of news shortly after: they were establishing a sect named the 'Sword Sect.'"
"Any Soul Master in the continent who inherited an Ordinary sword-type Martial Soul could join. The Sword Sect would be divided into five major sword lineages.
"Upon joining, one could choose a lineage, and the Yun Clan would guide them on how to walk the path of the Single-Attribute Fusion Stream to evolve their Martial Soul."
"However, the requirement was to respect the Yun Clan as the Sect Leader's lineage. Furthermore, Soul Master clans joining as a whole had to choose a single lineage for the entire clan; they were not allowed to split across multiple lineages."
"This news spread across the entire continent like wildfire. Combined with the fact that the Yun Clan had just shared the method for solving the defects of Ordinary Tool Martial Souls, their prestige soared."
"For a time, the Yun Clan became the focal point of the continent, attracting the gaze of every major power."
"It could be said that over seventy percent of the ordinary sword-type Soul Masters on the continent joined the Sword Sect. Through this, the Yun Clan's strength exploded, instantly becoming a first-rate power on the continent."
"Even when compared to those top-tier Soul Master clans with thousands of years of heritage, they were only slightly lacking at the Titled Douluo level; in all other aspects, they were no longer inferior."
