The center of Yun Yi's dantian turned into a blue ocean under the gathering of soul power, and at this time Yun Yi's spirit was like an invisible hand stirring in this blue ocean. As the speed of soul power flowing in his dantian continued to increase, Yun Yi also found that his dantian seemed to have turned into a black hole. He could feel that the speed at which Xuantian Gong absorbed external energy was also increasing.

Having such a speed of soul power flowing in the body is extremely dangerous for ordinary soul masters, but Yun Yi's body is even stronger than he imagined. With such a speed of flow and the soul power being extremely full and constantly increasing in volume, the meridians in Yun Yi's body are like cast steel, with only slight signs of expansion.

"The circulation speed has become inertia. What should be done next is to continuously compress the soul power." Yun Yi said silently in his heart.

Then, Yun Yi started from his Dantian under the extremely fast flow rate of soul power, and tried hard to squeeze the soul power. Under Yun Yi's squeezing, Yun Yi found that the soul power in Dantian not only did not slow down the flow rate due to the compression of soul power, but the flow rate became faster under the continuous squeezing, and this speed was still rising, quickly condensing into substance. Yun Yi could see the blue center in Dantian, and a bit of deep blue was slowly expanding.

"So simple?" Yun Yi was quite surprised when he saw that bit of deep blue.

Everything seemed to be a natural progression. Although Yun Yi was surprised, he did not take it lightly. He continued to add to the deep blue in his dantian, trying to gradually expand that spot of deep blue.

As time went by, the deep blue in the spiritual perception expanded rapidly, and now it has reached the size of a longan. Yun Yi also began to feel the benefits brought by the soul core. The soul core is essentially like adding a controllable black hole to the soul master's body, which not only improves the quality and stock of the soul master's soul power, but also has extremely amazing efficiency in output and absorption.

As time passed little by little, I don’t know how much time passed.

Under Yun Yi's introspection, the soul core in his dantian was about the size of an egg. The blue soul core was like a star and the surrounding soul power was as dense as a nebula, rotating around the soul core and gradually stabilizing.

Yun Yi let go of his control and watched the soul core automatically operating in his dantian. There was nothing unusual and he couldn't help but feel happy. After feeling it carefully, Yun Yi could clearly feel that the soul power in his body was gradually recovering. The speed of soul power recovery and operation was much faster than before. Even the efficiency of Xuantian Gong had become higher.

"Can it be considered successful? The soul core should also have a size." Yun Yi murmured in his heart.

Yun Yi didn't know what a soul core looked like, and he hadn't even asked Bibi Dong about the specific standards. Today he just wanted to give it a try, but he didn't expect it to be so smooth.

The progress of all things can be summarized in terms of quantity and quality, so Yun Yi continued to try to make his soul core grow, but no matter how Yun Yi compressed his soul power, the blue soul core showed no signs of growing again, so Yun Yi had no choice but to give up.

"Huo Gua also succeeded in condensing his soul core when he reached the Soul Saint level."

With this in mind, Yun Yi did not delve into the soul core that already looked like a real thing. According to his idea, the body is the carrier of energy, and the soul core is, in a sense, an aggregate of energy. If Yun Yi's soul core is smaller than others, or there is something wrong with it, then there is only one possibility, and that is a problem with the body.

"Let's ask the ghost tomorrow."

Feeling that it was still dark outside, Yun Yi continued to practice Xuantian Gong.

The next day.

When Yun Yi came to the training ground again, Gui Mei looked at Yun Yi as if he had seen a ghost. He immediately grabbed Yun Yi by the collar and asked, "Did you successfully condense your soul core yesterday?"

Yun Yi was a little surprised and asked, "You can see this too?"

"Nonsense, the aura of a soul master who successfully condensed a soul core is completely different from that of a soul master who has not. " Guimei still looked at Yun Yi with an expression as if he had seen a ghost.

"What's so surprising about this? Isn't it just a soul core? I followed my sister's instructions and tried it last night and it succeeded. It's not difficult. I was wondering if there was something wrong with my soul core." Yun Yi said with a smile.

"Don't you feel pain in your body when you condense your soul core? Squeezing your soul power into a soul core under that kind of pain from the inside out will undoubtedly deepen your pain, and the soul master's control will also decrease because of this pain." Guimei looked at Yun Yi and asked.

"Why do I feel pain? Everything is going well. Shouldn't I speed up the flow of soul power so that it forms a cyclone in the dantian, and then compress it step by step? Apart from some swelling, I don't feel anything." Yun Yi spread his hands.

Guimei instantly grabbed Yun Yi's wrist, and when he felt Yun Yi's solid body, his expression became complicated. The next moment, when he felt the egg-sized soul core in Yun Yi's body, his expression relaxed slightly.

Seeing Gui Mei's expression, Yun Yi thought there was something wrong with his body, and hurriedly asked Gui Mei, "Is there anything wrong with the thing inside my body? Yesterday I thought it was not big enough and was going to continue compressing it, but no matter how I compressed it, it showed no signs of continuing to grow."

Hearing this, Gui Mei sneered and said, "Boy, you don't need to compress it anymore. The bigger the soul core is, the better it is. The size of your soul core has surpassed many Title Douluo. The reason why your soul core is the current size is because your method of compressing soul power is not good enough. As your soul power control improves, your soul core will become smaller and smaller. I can't comment on you. After all, according to the records of the Spirit Hall, you are the first person who tried to condense a soul core when you were a Soul Emperor. If I have to say, the current state can only be regarded as a prototype, but it can also be regarded as a successful condensation."

Yun Yi suddenly realized what was going on and asked, "Then what method should be used to compress the soul power?"

"When you were practicing, you should have been able to feel the existence of free energy between heaven and earth. If you compare it to the smallest unit of soul power, what you need to do is to compress every bit of soul power into the shape of that smallest unit, and then build your own soul core. If you concentrate and compress the entire Dantian like you did, it will be as big as it is now."

After Gui Mei finished speaking, a ball of blue soul power condensed in his hand. Under Yun Yi's gaze, the soul power slowly turned into a ball and rotated at an extremely fast frequency.

"Just like this." The ghost said with a bit of pride on his face.

Yun Yi looked at the glass-bead-sized ball of soul power in the ghost's palm with a strange look on his face. It seemed that the only difference between this thing and the special move of the protagonist of a foreign anime was the size.

"The soul power after compression can also have considerable power." Guimei said as he threw the ball of soul power in his hand out.

As the ball of soul power fell, a very standard circular pit appeared on the ground. Although it was not big, its power did not dissipate at all.

"This is also a direction for developing a self-created soul skill." Yun Yi said softly. Hearing this, Gui Mei shook his head and said, "Boy, this can't be called a self-created soul skill."

"Oh?" Yun Yi looked at the ghost with curiosity.

Gui Mei said seriously, "Boy, everything about a soul master is based on the martial soul. Whether it is a soul skill or a self-created soul skill, the word "soul" represents the martial soul rather than soul power. Although such a move utilizes soul power and the soul master's strong control, it does not involve the martial soul. Without the participation of the martial soul, even if you develop it deeply, its power may not be as good as a soul skill, or a move of a weapon martial soul."

Yun Yi fell into deep thought after hearing this, and Guimei continued to speak.

"I've watched your competition. Although I don't know how you use the abilities of various attributes, even if you can use the wind attribute domain, it only means that your understanding of the wind attribute exceeds that of ordinary wind attribute spirit masters. When facing a spirit master with the same level of wind attribute martial spirit, even if you can be slightly better than your opponent in the same attribute during the battle, it is because the martial spirit has given you a strong basic attribute and a strong learning and comprehension ability. When you really meet a master who also has the wind attribute domain, you will understand that the martial spirit is what really determines the gap."

"The gap in martial spirit?" Yun Yi murmured softly.

"Yes, after a long period of research in the hall, we found that some martial souls have stronger attribute reactions than martial souls of the same attribute, thus easily suppressing opponents of the same attribute. Of course, they are also limited by their martial souls, that is, their martial souls are not sensitive to other attributes during meditation, so their cultivation will be slower than that of normal soul masters."

Yun Yi was surprised when he heard this. It seemed that the prototype of the extreme attribute theory had already been formed at this time.

"Since I have taught you, I will say a few more words. It is certainly easy for you to learn various abilities, but I still hope that you can explore the true power of your own martial soul. Just like the ability you used in front of Dugu Bo's poison miasma a few days ago, that is the true power of the martial soul."

"Silver level awakening?" Yun Yi murmured in his heart. It seemed that he was indeed too concerned about learning other people's abilities.

"Boy, all I've seen about your martial arts development is your powerful learning ability, your condition that day, and your huge appetite and digestive ability. This is too little. Think about it carefully." Guimei said lightly.

Yun Yi looked at Gui Mei and nodded seriously, then bowed slightly to Gui Mei and said, "I'm grateful for your advice, kid."

Seeing this, Gui Mei grinned and said, "Now that you understand, I won't waste any more words. Boy, today's training begins."

After saying that, the ghostly figure instantly disappeared in front of Yun Yi.

Yun Yi was also learning and applying at the moment, and instantly opened the silver level awakening. Since he wanted to develop, he naturally had to understand the limits of his body as much as possible.

Then a silver light and shadow appeared on the whole body of the person. The moment the ghost was about to touch Yun Yi, Yun Yi suddenly felt a chill.

Yun Yi twisted his body subconsciously and actually avoided the ghost's attack. The ghost was also extremely surprised. You know, Yun Yi was just beaten yesterday and didn't dodge at all.

"Is this feeling my body reminding me?" Yun Yi murmured in his heart, his face gradually becoming excited.

The human body has many ways to receive signals. No matter what method the ghost uses, even if he uses his mental power to erase his own breath, the ghost's attack is ultimately physical. Even if there is a slight wind from the fist, this moment is enough for Yun Yi to receive the attack signal and respond.

The ghost did not believe in evil and used his powerful mental power to influence Yun Yi, and then launched a quick attack, but without exception, Yun Yi dodged all of them.

"Not only has his perception been greatly enhanced, his speed and strength have also been greatly improved. What on earth is this silver light and shadow on this kid? I have clearly forced him to release his abilities, but he can still sense my attack and even dodge it accurately." The ghost secretly said in his heart.

A terrible idea suddenly appeared in the ghost's mind. Yun Yi did not actually sense his breath, but used his body to receive some special signals.

With this in mind, the ghost maintained his ability and instantly disappeared in front of Yun Yi, and flashed behind Yun Yi. This time he did not swing his fist, but tried to keep his movements as low as possible and raised his hand to grab Yun Yi. When he was about to touch Yun Yi, Yun Yi turned around instantly and blocked the ghost's hand.

"Sure enough!" Guimei said secretly in his heart, with a look of horror on his face. Yun Yi's perception method was indeed at some special level. When he slowed down and grabbed Yun Yi, it would actually allow Yun Yi to receive this special signal later.

"Senior Ghost, although you have affected my mental power, every organ in my body can receive different signals. For example, the wind from your fist allows the hair on my body to receive some information." Yun Yi said with a smile.

"A magical martial spirit." The ghost couldn't help but admire.

Guimei looked at Yun Yi with a face full of relief. It was a good thing that their Spirit Hall had picked up someone like Yun Yi. If he stood on the opposite side of the Spirit Hall, he would definitely be a powerful enemy in the future.

“Senior, can you increase the intensity? This way, you won’t be able to hit me before my soul power runs out.” Yun Yi said with a smile.

Gui Mei shook his head slightly and said, "I am not good at physical attacks. Even if I use soul power to bless my strength, it may not be greater than yours. If I use my martial soul ability, it will lose its original purpose. Okay, continue."

Yun Yi smiled and said, "Senior Ghost, this is not an ordinary amplification skill. When I release this skill, all my abilities are almost doubled."

Gui Mei nodded after hearing this and said, "Hmm...not a bad skill."

"Senior, you don't seem to understand what I mean. This is not a 100% enhancement of attributes, but all the abilities of my body. I already understand the means you used to influence my mind just now. Now I have almost learned your method of using mental power to erase the aura." Yun Yi said with a smile.
