With the help of the Nine Nether Inferno, the breakthrough of the cultivation realm and the body of Vajra, his own strength has increased significantly, which makes Ye Yang's mood extremely happy, and at the same time, he is extremely looking forward to the next calcination and refining of the soul by the Nine Nether Inferno.

The soul is mysterious to ordinary human beings, mysterious and mysterious, invisible and intangible, vague, and doubtful, and it is not known whether human beings have souls or not. And for martial artists, the soul does exist, and it is also a very important existence.

Although martial artists who are new to cultivation are generally weak in cultivation and know little about their own souls, or only have a little contact and know very little, martial artists can also really feel the importance of the existence of the soul to a person.

Every human body is a vast treasure trove of countless treasures. And the soul is one of the most important treasures of the human body, indispensable. Because the soul represents a person's spirit and mind, the health and strength of a person's soul is the strength of a person's spirit and spirit.

And for ordinary people and martial artists, the health of the spirit and mind is also crucial. Whether it is the life of ordinary people or the cultivation of martial artists, it is inseparable from their own healthy mind and spirit. Just like a mentally handicapped person, he is not able to live independently, let alone work and cultivate, people will say that he is mentally incomplete and lacks aura, which is the reason why the soul is unhealthy, or it is the reason why the soul is incomplete due to injury.

And the strength of the human soul generally changes with age. Just like a newborn baby, he always wakes up for a while and falls into a deep sleep, because of the lack of spirit and energy, and his mind is incomplete, which means that his soul is still very weak. As time goes by, you will find that as his spirit gets better and better, he will no longer be sleepy, and the playing time will become longer and longer, until it is the same as the normal person's work and rest time, it will stop changing, or it will not change much. And his mind will slowly grow. From babbling to dressing and eating...... Until he can live independently, this is his mind has matured.

And this is also a sign that the soul has entered a mature period, and then the growth of the soul will slow down, and for a long time after that, the soul will hardly change much. However, after experiencing youth, middle age, and old age, you will find that your spirit will become worse and worse, the whole person will become more and more confused, and your memory will begin to decline slowly......

Although Ye Yang was looking forward to the Nine Hellfire Soul Refinement, there was still a trace of worry and resistance in his heart. The importance of the soul to a person is self-evident, if you use the Nine Hellfire to calcinate, if you are not careful, it will hurt the soul, at least the soul will fall into a deep sleep and become an idiot, and at the worst the soul will be annihilated and the soul will be scattered. No one would dare to try such a consequence lightly.

Although Ye Yang now has the soul realm of the middle stage of the Great Soul Master, and has the help of the True Fire Soul Refining Technique to cultivate, he has also encountered a bottleneck in soul cultivation. With the continuous calcination and refining of the soul in the dantian fire, the growth of the soul power is getting slower and slower, but I am afraid that with the growth of time, the effect of the dantian fire on the soul will become dispensable. If he can successfully calcine and refine his soul with the Nine Hellfire, he will definitely be able to break the bottleneck of his current soul cultivation and break through to a higher realm, and it is even possible to break through to the Soul Sect in one fell swoop, and it is not impossible to awaken the soul skill he dreamed of.

With his desire for soul skills, Ye Yang took a deep breath, calmed down his ups and downs at this time, gritted his teeth, and his eyes were full of determination. Done with his knees crossed, calmed down, mobilized the nine hellfires in the dantian, and began to use it to carefully calcine the soul according to the method of true fire soul refining technique. As the soul and the Nine Hellfire suddenly came into contact, a scorching sensation from the depths of the soul that life was worse than death instantly eroded Ye Yang's senses. The closed eyes suddenly opened, and the eyes were filled with a rich blood color, like blood cells, as if they were about to burst open in the next moment. Clenched his teeth hard, and with a creaking sound, his teeth seemed to be about to be crushed. A drop of sweat the size of a bean kept sliding down his bruised and hideous face. At the same time, the body that was instantly soaked in sweat, as if it had been struck by lightning, trembled violently, and began to tremble incessantly, and the face, which was still a little bloody, also became miserable. Enduring the scorching pain coming from his soul, Ye Yang's eyes slowly closed, and his mind gradually sank into his body, mobilizing the true qi in his body to suppress it. Although there is the suppression of true qi, it is obviously not very effective. With the further calcination and refining of the Nine Hellfires, his soul, which had begun to tremble, was even more distorted by the smoke, and the pain caused directly caused Ye Yang's body to continue to cramp indirectly, the muscles all over his body were tense, and the green tendons like flesh and insects continued to stir, and his pale face was without the slightest blood.

Under the trembling in the depths of his soul, the feeling that life was worse than death became stronger and stronger, and Ye Yang persevered for a whole hour and stopped cultivating. It's not that he can't hold on, it's that his true qi and soul power are consumed too quickly in this situation. At this time, his true qi and soul power were close to exhaustion, so he could only give up continuing to refine his soul and began to slowly recover.

It also took about an hour for Ye Yang's true qi and soul to return to their peak state. Immediately, he began to bear the burning sensation of his soul that he was not willing to live again, and he used the Nine Hell Fire to calcinate and temper his soul. Just consume like this, and then recover, over and over again, calcining and refining your soul over and over again......

As the Nine Hell Fire calcined and tempered his soul, Ye Yang gradually became numb to the painful feeling, although the burning sensation did not weaken in the slightest, but it continued to increase, but as his senses gradually became numb, the painful feeling that made the soul constantly distort became not particularly violent.

The sweet time always feels very short, and it will slip away inadvertently, and you can't keep it if you want to, but the painful time feels incomparably long, as if there is no end, and you can't get rid of it if you want to. But time will slowly pass no matter what. After a day and a night of repeated calcination and refining of the soul by the Nine Hellfire, finally, Ye Yang stopped continuing to refine the soul, and the painful feeling and torment also disappeared with the return of the Nine Hellfire to the dantian.

"This, this is the soul technique!"
