For now, he could only ask why Yu Tianheng had come.
Yu Tianheng said, "Nothing in particular. I just came to visit you, uncle, and see how you were doing."
Yu Xiaogang smiled. "How could I be doing? The same as ever. My cultivation is stuck at level twenty-nine, and I can never advance any further, so I can only devote all my time to Martial Soul Theory research."
Yu Tianheng nodded and continued, "Uncle, tomorrow I'm going with grandfather to hunt a Soul Beast and obtain the First Soul Ring for my Blue Lightning Tyrant Dragon Martial Soul. You've spent years researching theories about Martial Souls, so I imagine you've studied our clan's Blue Lightning Tyrant Dragon Martial Soul, passed down through the generations, most thoroughly. Could you give me some advice?"
When Yu Xiaogang heard his nephew ask him this, his eyes lit up at once.
He had spent many years researching Martial Soul Theory. Although most of it was just talk on paper, with no practical experience, he had the Blue Lightning Tyrant Dragon Clan behind him and access to a great deal of information ordinary people could hardly come by.
After years of research, he had made some achievements.
Yu Xiaogang then began discussing the Blue Lightning Tyrant Dragon Martial Soul with Yu Tianheng.
This Martial Soul was among the very best Beast Martial Souls, hailed as the most powerful Martial Soul in the world and inherited by the direct descendants of the Blue Lightning Tyrant Dragon Clan. At the same time, however, it was far more likely to mutate than other Martial Souls.
Yu Xiaogang himself was one example. His Martial Soul had mutated during his Martial Soul Awakening and developed into a Trash Martial Soul.
There were also quite a few cases of mutated Martial Souls within the clan.
And few in the clan could fully awaken the power of their Martial Souls, which also meant that even fewer managed to break through to become Titled Douluo.
At present, Yu Yuanzhen was the only one in the clan who had reached the Titled Douluo level. The rest, even some elders who had lived for a very long time, had only reached the Soul Douluo level.
Starting at level thirty, each time a Blue Lightning Tyrant Dragon Soul Master obtained a Soul Ring, another part of their body would transform into that of a dragon when they used their Martial Soul. At level seventy, a Blue Lightning Tyrant Dragon Soul Master could truly transform into a dragon and unleash a terrifying amount of power. They were acclaimed as the most fearsome Power Attack System Soul Masters of their level.
Besides that, Soul Masters with the Blue Lightning Tyrant Dragon Martial Soul could also control lightning and possessed powerful physical strength.
This gave Yu Tianheng quite a bit of inspiration. He had the Heavenly Mandate System and could use Heavenly Mandate Points to buy cultivation techniques from it. When the time came, he could look for techniques related to the body or the control of lightning.
After that, Yu Xiaogang told Yu Tianheng about his research into Martial Soul Theory.
In the words of the original work, it was the "Ten Core Competencies of Martial Soul."
So far, Yu Xiaogang had only worked out five of them.
1. The amount of Innate Soul Power was directly proportional to the quality of the Martial Soul.
2. Martial Soul Mimicry Theory: plant-type Soul Masters could absorb beast-type Soul Rings.
3. Soul Ring bottlenecks could not prevent a Soul Master's Soul Power from increasing.
4. Fusion of Martial Souls from different bodies.
5. The amplification effect of a Martial Soul Avatar was directly proportional to the quality of the Martial Soul itself.
After listening, Yu Tianheng put on a surprised expression, but inwardly, to tell the truth, he was somewhat disdainful.
These theories seemed profound, but in reality, experienced Soul Masters, such as Titled Douluo or Soul Douluo, could discover them.
It was just that they were busy cultivating and had no time to publish them, while Yu Xiaogang had little talent for cultivation and could only research these things to pass the time and prove himself.
First, the amount of Innate Soul Power was directly proportional to the quality of the Martial Soul. That was sheer nonsense. Soul Masters who could awaken high-quality Martial Souls were naturally gifted to begin with, so naturally their Innate Soul Power couldn't be all that low. What was there to discover? It was a plain fact.
Second, plant-type Soul Masters could absorb beast-type Soul Rings. Looking back over the history of Douluo Continent, Soul Masters had definitely tried this before. There was nothing obviously wrong with the theory itself, but the problem was that it was far too easy to understand. In all the years the Soul Master World had existed, had no Soul Master ever absorbed a Soul Ring from another species? He didn't believe Yu Xiaogang was the only person on the entire continent capable of drawing an inference from one example.
The third, fourth, and fifth theories that followed had all sorts of holes in them too. Not that they were holes, exactly; the main thing was that these matters were all very ordinary. In Yu Tianheng's view, any powerful Soul Master who studied them carefully could discover a thing or two. It was just that they were all busy cultivating and didn't have the time to examine them closely.
There also seemed to be a fairly famous theory in the original work: "There are no trash Martial Souls, only trash Soul Masters."
Words like that were only useful when the protagonist said them. They were no use coming from Yu Xiaogang. After all, he had cultivated for so many years, yet there was no sign that he had grown much stronger.
Though that was what he thought inwardly, Yu Tianheng still listened patiently to all of Yu Xiaogang's theories, praising them from time to time.
Perhaps Yu Xiaogang had been neglected for too long. Seeing Yu Tianheng, the only one willing to be close to him, who was also his own nephew, Yu Xiaogang laid down the burden in his heart and chatted with him for a long time, from daylight straight through to the evening.
Yu Tianheng listened patiently throughout.
"All right, Tian Heng, it's getting late. You still have to go with the clan leader tomorrow to hunt a Soul Beast and obtain a Soul Ring, so go back and rest," Yu Xiaogang said.
Yu Tianheng rose from his seat and bowed respectfully to Yu Xiaogang. "Then I'll go back and rest first, uncle. You should get some rest early too, and take care of yourself."
"If you ever decide to leave the clan and travel for a while, be sure to tell me beforehand. Otherwise, I'll worry."
"All right, I'll be sure to let you know when the time comes." Yu Xiaogang agreed happily.
Yu Tianheng left Yu Xiaogang's room and returned to his own.
After all, he was still just a child who had only recently turned six. It would be difficult to speak directly about Liu Erlong, or he would arouse suspicion. It would be better to wait a while and find an excuse to bring it up the next time he came to see Yu Xiaogang.
Early the next morning, Yu Tianheng got up, dressed, washed, and ate breakfast.
He headed toward the appointed place.
Yu Yuanzhen was already waiting there.
He wore a long blue-black robe and had a powerful presence and a dignified expression. With his hands clasped behind his back, he faintly gave the impression of Mount Tai bearing down on one's head, making people tense up without realizing it.
Even Yu Tianheng, who had lived two lives and had the system with him, couldn't help feeling that pressure.
"Grandfather!" Yu Tianheng hurried forward and bowed.
"Mm!" Yu Yuanzhen nodded slightly and asked, "I heard you went to see your uncle Yu Xiaogang yesterday?"
Yu Tianheng nodded. "Yes. We're family, after all, bound by blood in a bond that can't be severed. As his junior, I should visit him too."
Hearing this answer, Yu Yuanzhen's heart trembled.
Bound by blood in a bond that couldn't be severed.
Yes!
He was his own son, after all. How could he not worry about him?
But the clan had its rules, and as clan leader, he naturally had to lead by example.
