âDonât tire yourself out, Yuhao. You look so worn out.â Elder Xuan smacked the dust off his shoulders and said concernedly.
Huo Yuhao laughed in embarrassment. Bei Beiâs warning fell on deaf ears. He was excited after completing his experiments, and was eager to tell Elder Xuan everything about the mysteries of soul power.
âElder Xuan, wasnât I possessed by the Beast God Di Tian when I was resisting Elder Ye Xishui? Then, the Beast God poured in his strength into my body from afar through spatial power. He descended using my body. Even though my passageways were damaged following that, I managed to understand some certain traits of Di Tianâs soul power. When I did my research after that, I found out something strange.â
Huo Yuhao recounted his discoveries, along with the details of his experiments to Elder Xuan.
Elder Xuan was still smiling when he first started, and nodding his head from time to time. He was very pleased with Huo Yuhaoâs curiosity. However, his expression slowly changed as he continued to listen.
He performed high-pressure compression on his soul power and controlled it outside his body, creating a spatial distortion and allowing him to imitate Di Tianâs black hole soul power.
This kid is too brazen.
ââ¦Elder Xuan, whatever knowledge the academy taught before only applies to Soul Douluo and below. Thereâs no other knowledge beyond Soul Douluo. When one becomes a Titled Douluo, what kind of changes will happen to his soul power? Is Di Tianâs black hole soul power only applicable for Ultimate Douluo? In other words, is he the only one with knowledge of it? Although they are both Ultimate Douluo, Di Tian was evidently stronger than Elder Ye Xishui. If Ye Xishui doesnât use the Death God, she wonât be Di Tianâs match in a direct confrontation.â
Elder Xuan silently nodded. He sighed before saying, âI didnât expect you to reach this level so quickly. Since youâve asked, I guess itâs fine that I tell you.â
âYou arenât wrong. When a soul master becomes a Titled Douluo, his soul power will transform from its original fluid state to a solid state. Thatâs the Rank 90 bottleneck, and the soul master will obtain his ninth soul ring to become a Titled Douluo. This is a very difficult bottleneck to break through for most soul masters. This is why there are so many Soul Douluo, but a scarcity of Titled Douluo.â
âThereâs a very big problem when oneâs soul power changes from a fluid state to a solid state. Itâs very difficult to cultivate soul power in the solid state. Letâs not talk about those Soul Douluo who canât transform to become a Titled Douluo. Letâs only talk about Titled Douluo. Youâve already sparred with many Titled Douluo. Have you ever realized that even Titled Douluo of the same rank can actually differ a lot in their abilities?â
Huo Yuhao immediately nodded and said, âYes! Iâve discovered this point. Isnât this because of oneâs martial soul?â
Elder Xuan smiled and said, âThatâs right. It has some relation to oneâs martial soul. The stronger oneâs martial soul is, the better he is able to unleash the strength of it when he combines it with his soul power. However, you might know about something. The stronger oneâs martial soul is, the greater the amount of soul power during cultivation. This is because oneâs martial soul can contain a part of his soul power. The stronger a martial soul, the greater the amount of soul power it can store.â
âOne can store a portion of his soul power in his martial soul?â Huo Yuhao was astonished. He really did not know about this.
Elder Xuan smiled and said, âYes. You should be realizing it now. A soul master can unleash his Martial Soul True Body if heâs at least a Soul Sage. His Martial Soul True Body can help him to store some of his soul power. Youâll only learn such knowledge in the academy if youâre at least a Soul Sage. You didnât realize it because the amount of soul power you have is already greater than other soul masters of the same rank. Donât forget, you have twin martial souls.â
Huo Yuhao pondered, then asked, âDoes this mean that it is very difficult for a Titled Douluo to improve further when his soul power reaches a solid state?â
Elder Xuan smiled and nodded lightly, âThatâs right, youâre correct. The reason is also very simple. If your soul power is in the gaseous or liquid state, it can flow inside your body. Now, let me ask you, can your soul power still flow if itâs in a solid state?â
Huo Yuhao was stunned for a moment, and subconsciously shook his head. Yes! How can oneâs soul power flow inside his body if itâs in a solid state?
Elder Xuan said, âYour research is going in the right direction. In fact, the situation that youâve laid out is exactly the soul core that only appears for Titled Douluo. It refers to the core of soul power, the foundation of a Titled Douluo. Soul power is compressed from a fluid state to a solid state, which is then immersed in the dantian of a soul master. That is the soul core. The soul core revolves continuously, and will absorb external soul power through the soul master for the soul master to use. Whether it is in terms of fighting strength or recovery ability, the soul master will be stronger than before.â
âHowever, it is much more difficult to improve once oneâs soul power solidifies compared to when itâs in the fluid or gaseous state. This is because a human canât possibly circulate solid soul power through his body. This is why a human can only dissect the solid soul power in his body into beads before controlling the circulation of his soul power in the gaseous or fluid state. Not only is this process difficult, but it is also very dangerous. As a result, some soul masters who didnât think that they were talented would give up on further improvements after they became Titled Douluo. They would remain at Rank 91. This is very safe for them.â
Itâs actually so complicated? Huo Yuhao was shocked when he heard that.
Elder Xuan continued, saying, âHowever, itâs not entirely true that soul power canât circulate in oneâs body in the solid state. If a soul masterâs spiritual power is strong enough that he can control the beads of soul power to appear in the gaseous or fluid state, he can naturally circulate his soul power. Given this, solid, fluid and gaseous states could possibly exist together. To control oneâs soul power at this level, one can only be a Transcendent Douluo. As a result, after becoming a Transcendent Douluo, cultivation might actually become easier. At least thereâs a correct cultivation method.â
âOf course, Transcendent Douluo would still find it difficult to improve. Thereâs a limit to how much soul power a human body can handle. It can still be compressed in the gaseous or fluid state, and it is already highly compressed in the solid state. It can no longer be further compressed. In order to allow oneâs body to handle more soul power, it comes down to the question that you asked earlier â why does Di Tianâs soul power contain such strong spatial power?â
âDi Tian has an eight hundred thousand year cultivation. Although he has not lived in this world for eight hundred thousand years, he has still lived much longer than us. Throughout his entire life, he has been understanding the mysteries of space and time, granting him his current cultivation. No one on the continent can compare to him in this aspect. His soul power, which is every little black hole that you saw, contains an immense amount of compressed soul power. It is stored in his body using time and spatial power, which enables him to handle it. Once a  fight breaks out, he can unleash immense fighting strength by controlling his soul power.â
âMy current soul power is Rank 98. All these years, Iâve been troubled by how to control that spatial power and stabilize it after compressing my soul power. I can perform some simple control of spatial power. Come, take a look.â
As he spoke, Elder Xuan stretched out his hand, and a ball of yellow light appeared out of nothing in his palm. It was a yellow ball of light, which looked very real. There were thin spatial cracks around it.
Earth-type soul power! This was clearly Elder Xuanâs solidified soul power!
Elder Xuanâs eyes brightened. Suddenly, the spatial cracks that surrounded the ball started to widen, and the ball started to collapse inward. A small black hole was formed. A terrifying suction force dragged Huo Yuhao toward it, and he almost knocked into Elder Xuan.
After that black hole formed, it started to revolve at high speed. The origin energy in the air started to be sucked into the black hole.
The yellow light on Elder Xuanâs body became more intense. The little black hole stabilized as it was surrounded by a layer of gentle yellow light. It stopped spinning faster, but revolved at a constant speed.
âThis is roughly how it is in Di Tianâs body. He uses his own soul power to cause a collapse in space, forming a black hole that can devour origin energy. Theoretically speaking, this black hole can continuously devour origin energy. However, there would be instability if I canât control it, which would eventually lead to an explosion. I heard Elder Mu mention that if an Ultimate Douluo can complete a black hole and maintain it at a limit that he can handle, the black hole would be able to remain indefinitely. In that case, this black hole can even devour our entire continent.â
âOf course. Such a possibility is very rare. Elder Mu was only making deductions too. Such a black hole soul power would require immense spiritual power to be controlled. After itâs controlled, it can be absorbed into oneâs body. I can complete such a process, but I canât transform my soul power in that way like Di Tian. Currently, thereâs only one black hole of soul power in my body right now. Itâs my soul core. The soul power thatâs flowing in my body is still existing in three states.â
âIf I can transform one-tenth of the soul power in my body into a black hole, I can create a second black hole soul core, possibly in my chest or brow, thereby becoming an Ultimate Douluo. However, itâs not easy! Iâve already tried many times, but Iâve always missed by a bit. Compared to substituting my soul power, creating a second soul core is easier. Elder Mu and Long Xiaoyao both took this path. I think Ye Xishui did the same too. Only Di Tian took a different path. This is why he is much stronger than most ordinary Ultimate Douluo.
