There was a storm in Gui Mei's heart, and he suddenly understood what the silver light and shadow on Yun Yi's body was. According to Yun Yi's description, this was a martial soul talent ability similar to the dragon transformation of the Blue Lightning Tyrannosaurus Rex martial soul. Martial souls with this talent ability are all top-notch.

Gui Mei thought about it and calmed down. Yun Yi's body was so strong that he didn't feel any pain even when his soul power was constantly compressed. With such a strong body, it seemed natural for him to have such an excellent talent.

Then the ghost said to Yun Yi calmly, "Words are not enough, go and give it a try."

"Come with me." Yun Yi said with a smile. Since he was going to perform a test, he certainly couldn't choose a ghost as the target. Yun Yi was still unable to shake the ghost's mental power.

Then the two of them slowly walked out of the training ground and found a student from the Wuhun Hall Academy. Yun Yi's eyes glowed purple, and then he said, "Senior, look."

In fact, everyone has his or her own mental power, but when one's strength is weak, the mental power's perception of the outside world is not obvious and is extremely small. No matter what behavior is done in the real world, there will be waves generated by its actions. Fluctuations of different frequencies, amplitudes, and wavelengths can convey different information and thus be received by the mental power of others.

What Yun Yi needs to do is to use his powerful mental power to disrupt the student's not-so-strong mental power, destroy the ability of others to receive mental power and create illusions.

Soon, the student bumped into a big tree under Yun Yi's influence. Seeing this, Guimei had a complicated expression. Although Yun Yi's techniques still had many flaws, as Yun Yi said, he had already learned it.

Guimei looked at Yun Yi with a slightly complicated expression. According to his expectations, even if Yun Yi learned quickly, it would take at least three to five months to apply such an advanced method as mental power. However, he did not expect that Yun Yi's silver status skill could even amplify his personal learning ability.

"How?" Yun Yi asked with a smile.

The ghost coughed lightly and said with some embarrassment, "Well, not bad, I have learned it, but I am still far from being able to control the enemy."

Yun Yi rolled his eyes at Gui Mei and said, "You are a Titled Douluo, and your martial spirit is more spiritual. I am definitely not as good as you in more subtle aspects."

Hearing this, the ghost shook his head and said, "Boy, I think that compared with our two martial souls, your martial soul may have a little more advantage in terms of spirit. The body is the foundation of everything for a soul master. Without the body, even the most powerful spirit is useless. The reason why His Holiness asked you to come here to study is that he hopes that you can use our power to more comprehensively develop the ability of your martial soul. Your magical eyes, as a part of the body, are an excellent medium, a medium for communicating spiritual power."

Yun Yi's eyes lit up slightly. Indeed, eyes were also considered a part of his martial soul. Why couldn't he become another Huo Yuhao in the spiritual realm? Of course, Yun Yi didn't think he could surpass Huo Yuhao ten thousand years later in the original work in the spiritual realm, but in this era when the application of spiritual power was still very rudimentary, Yun Yi believed that as long as he was willing to learn and develop, no one in this era would be his opponent in the spiritual realm.

"Then let's continue?" Yun Yi asked with a smile.

Gui Mei shook his head slightly and said, "Boy, you have almost learned it. You can continue to go deeper in this direction. Although my martial soul is more spiritual, I did not focus on this direction. Not everyone is as lucky as Nana to have a teacher like His Holiness the Pope. Most of the soul rings I choose are of dark attribute, slightly more agile. My soul ring configuration is not much different from that guy Gui Bao, and mental power is more of a means of auxiliary attack."

"So you are not a spiritual master?" Yun Yi had a strange look on his face.

"I didn't say I was. Didn't I ask you at that time? I am a ghost. What kind of soul ring do you think I will hunt?" The ghost said with a slight smile on his face.

Yun Yi remained silent upon hearing this. He suddenly remembered the time when he helped Tang San forge a hidden weapon, a Zhuge Divine Crossbow.

Gui Mei looked at Yun Yi with a look of emotion and said, "A child who died once when his martial spirit awakened, does he still have any choice?"

"Sorry, senior." Yun Yi said softly.

Soul beasts with spiritual attributes may be easier to find now than in the Huo Gua era ten thousand years later, but the development of spiritual power is still in a very barbaric era. Many low-level soul masters don’t even know what spiritual power is, let alone come into contact with knowledge about spiritual power. Hu Liena may be the first pure spiritual soul master. Only she, as a disciple of Bibi Dong and the Holy Maiden of the Spirit Hall, has the strength to choose such a path that has not yet been fully developed. This is due to the limitations of the times.

"Since you have found a new direction, I have nothing more to teach you. Perhaps you can learn more by going to the Star Dou Great Forest to find some spiritual beasts. Boy, let me give you one last sentence: the essence of spiritual power is input and output."

After saying that, the ghostly figure disappeared in front of Yun Yi, and then Yun Yi bowed slightly towards the place where the ghost disappeared.

"Input and output." Yun Yi savored this sentence carefully, thinking of all the skills related to the spirit eyes of Huo Yuhao.

Indeed, most of Huo Yuhao's soul skills related to his spiritual eyes are inseparable from these words: mental detection, mental sharing, mental interference, soul shock, imitation, group weakness, mental confusion, and mental replication. These are actually all applications of mental power, and according to Yun Yi's estimation, the ghostly abilities should be classified in the category of mental interference.

Of course, starting from Huo Gua's sixth soul skill, everything became beyond the standard. The subsequent soul skills were more of a reflection of the soul beast's bloodline. This special ability that exists in the bloodline cannot be obtained through learning.

"Now that we have the Huo Gua template, we can try to develop it in these directions." Yun Yi murmured in his heart.

"Input and output. First try to output your own mental power and develop mental detection."

Yun Yi was very active and would start trying out anything he thought of. Then he sat down on the ground, slowly opened his eyes, and began to try to maximize his mental power.

Yun Yi used his soul power to slowly flow to the center of his eyebrows above his dantian. The first thing Yun Yi felt was a trace of cold soul power fluctuation injected into his mind. It was a kind of energy fluctuation that made him feel very comfortable.

The cool breath continued to flow into Yun Yi's brows, gradually stimulating his brain. Wherever it passed, his brain seemed to be gradually opened up.

A wonderful sense of clarity appeared in Yun Yi's mind. This was a clarity that Yun Yi had never felt before. At this moment, he found that many things that he had not figured out before suddenly became clear to him.

Under the continuous effect of soul power, his entire brain seemed to be separated from his body. Yun Yi found that he could control everything with just a thought. Now he didn't need to observe with his eyes, he could already clearly feel everything in the outside world.

Wherever his mental power passed, everything within a hundred meters around him was exposed. He even saw the battle of the students in the distance. The range that his mental power could scan was increasing at an alarming rate. His mental power continued to spread, one hundred meters, two hundred meters, and the ghosts that were leaving also felt Yun Yi's mental power and showed surprise on their faces.

"Good boy, you're such a fucking monster." The ghost said secretly in his heart.

Yun Yi could feel that there was still room for his mental power to expand, but he did not continue to release it. Instead, he restrained his mental power because he felt that his perception had become blurred.

At this time, Yun Yi was extremely envious of Huo Yuhao. Because of the million-year spiritual soul ring that Tian Meng had brought to Huo Gua, as long as the power of the soul ring was unlocked as Huo Gua's strength increased, the range of spiritual detection could be expanded as much as possible without any loss of accuracy.

Then Yun Yi slowly gathered his mental power. Through continuous attempts, he discovered that his mental detection had absolute accuracy within a hundred meters. Of course, this range would increase as Yun Yi's mental power increased.

In fact, according to Yun Yi's estimation, to be honest, even a hundred meters is not necessary. Yun Yi is not Huo Yuhao. He does not have those powerful long-range soul guides. With his body's reaction, even if it is a Titled Douluo of the Agility Attack System like Gui Mei, he can rely on his body's perception to keep up with his attack speed within ten meters of him.

This is equivalent to installing a radar on Yun Yi, but Yun Yi does not have a missile like a soul guide.

This is indeed the case in this era. Most Titled Douluo have mastered a certain range of mental detection, but most of them are used for vigilance and tracking. If a soul guide appears, it can be used as a radar lock.

"It seems that auxiliary skills such as spiritual detection are not suitable for me. Even now, the Sun and Moon Continent should still be in the starting stage of soul guides." Yun Yi murmured.

Thinking of this, Yun Yi slowly turned around and walked towards where the two girls were.

On the other side, the ghost did not return to where he lived, but came to the Pope's Palace.

"Elder Ghost, His Holiness the Pope invites you." The palace guard bowed respectfully to the ghost.

The ghost nodded slightly, then slowly walked into the side hall.

When the ghost came in front of Bibi Dong, Bibi Dong put down her pen and slowly raised her head, "What's the matter, Elder Ghost?"

"That child has completed the condensation of his soul core. Although it is not perfect yet, it has taken shape. He has also successfully mastered the general usage of mental power. I have nothing more to teach him." The ghost said respectfully.

For someone like Yun Yi who can draw inferences from what he has learned, Guimei did not teach him from simple perception in the normal way. Instead, he chose to directly teach Yun Yi how to apply mental power in combat. Of course, he also wanted to beat Yun Yi up, but he did not expect that Yun Yi would learn it the next day after he only beat him up for one day.

Upon hearing the news, Bibi Dong's hand holding the feather pen trembled slightly, her face full of excitement. She guessed that Yun Yi should be able to learn quickly, but she did not expect that Yun Yi had mastered the general usage of mental power in just a few days.

But soon a trace of sadness appeared on Bibi Dong's face. It was not a good thing for a student to be too smart. She suddenly realized that she didn't seem to know how to arrange Yun Yi now. The main purpose of letting Yun Yi fight with the Titled Douluo was to let Yun Yi understand the general usage of mental power, but she didn't expect Yun Yi to pass the test of ghosts so quickly.

"Ghost Elder, thank you for your hard work." Bibi Dong said softly.

"It's a great experience to witness such a genius become a strong man." Guimei smiled.

Bibi Dong looked at the smile on Gui Mei's face and also smiled, "It seems that the child is very much to the taste of Elder Gui."

"Shame on you." The ghost said softly.

"Elder Ghost, do you think that child is still lacking something?" Bibi Dong asked Gui Mei for his opinion.

Gui Mei shook his head slightly and said, "His martial soul, body, mental strength, and soul power are all impeccable. No matter what he learns, it comes naturally. If there is anything he lacks, the only thing he lacks now is failure, and it is a crushing failure. Even if I don't use my martial soul, it will take me some effort to defeat him."

"Who do you think would be a better candidate for this failure?" Bibi Dong said softly.

The ghost hesitated for a moment, then slowly bowed and said, "Seventh Offering."

Bibi Dong's eyes flashed with brilliance when she heard this, and she said slowly, "Ghost Elder, you need to understand who you belong to now."

After that, an invisible pressure rose in the quiet side hall. A trace of cold sweat appeared on Gui Mei's forehead. He bowed slightly to Bibi Dong and said, "I understand, but the child's second martial spirit is a stick. I think it is most appropriate to let the Seventh Worshiper come. The Seventh Worshiper is very powerful. Under the same kind of weapon martial spirit, it is not a bad thing to let the child experience a failure. With the child's learning ability, he will definitely learn more."

After beating up Guimei, Bibi Dong's eyes returned to calm. A hint of hesitation flashed in her calm eyes. Of course she understood what Guimei said, but she also didn't want the person she trained to go against her in the future.

Guimei didn't say anything when he saw this. As people who were left in the Pope's Palace by the previous Pope, it was common for him and Yueguan to be beaten by Bibi Dong. However, he and Yueguan both understood what kind of person Bibi Dong was. It was no exaggeration to say that they had watched Bibi Dong grow up. Therefore, even after Bibi Dong became the Pope, they both continued to thrive in the Pope's Palace.

"Go down first. I still need to think about it." Bibi Dong waved her hand slightly and said to the ghost.

Seeing this, Gui Mei bowed slightly towards Bibi Dong and said respectfully, "Yes, Your Majesty."

Looking at the ghostly figure leaving, Bibi Dong's eyes flashed with a complicated look. She sighed slightly in her heart and continued to deal with the daily affairs of the Spirit Hall. (End of this chapter)
