"This ......" Gao Yun scratched his head and asked hesitantly, "What exactly is this field, and why do you need materials?"

The old man on the side couldn't help laughing and said: "The gap between the two of you is a bit big, so it's not surprising that some words and sentences don't match, and the material it says is not a real thing, but refers to your ability to comprehend the rules of nature." ”

"The ability to comprehend the rules of nature?" Gao Yun blinked and asked, "Are you talking about the understanding of various soul attributes?"

After "possessing" Yinghuang's body, although Gao Yun was in Yinghuang's body, he didn't actually need to control anything, just watched quietly from the sidelines, but Gao Yun was not idle, and he had been using his body to truly comprehend the use of his various soul tricks and skills.

After all, it was too rare for him to learn the moves of a top genius in the Netherworld at such a close distance, and it was many times better to experience it with his own body and soul than to watch it from the sidelines.

Although Gao Yun originally opened the soul source qi with the help of Xiao Bai and Xiao Hei, he knew very little about the use of soul power, and basically used it according to the usage of the spirit technique, or relied on the special affinity of the August Flowing Fire Sword to the soul power to play the role of soul power, or relied on his own contemplation.

And Ying Huang, as a powerhouse of the Earth and Netherworld, converted into the level of the plane where Gao Yun is located, is the True Immortal level of the Transcendence Sun Rank, which is much higher than the Four Directions Saint Realm that Gao Yun has heard of.

In addition to learning the actual combat moves, Gao Yun also took advantage of Ying Huang's leisure time to sort out the theoretical knowledge that Ying Huang had learned in his nearly twenty years of cultivation in his mind, which actually involved a lot of soul tricks.

Through the systematic study, he found a peculiar phenomenon, that is, the spell system soul recipe of the netherworld is also the same as the spirit recipe of the Seven Star Treasure Domain, each spell system soul recipe has its own attributes, the five elements of gold, wood, water, fire and earth, the wind system, the thunder system, the ice system, the light and dark attributes, including the rare space and time attributes, and so on.

However, unlike the cultivators of the Seven Star Treasure Domain, when the cultivators of the Netherworld used the soul technique, they used the soul power containing attribute energy instead of the aura, and their soul power was the same as Gao Yun's original soul source qi, which was concentrated in the heart vein position.

Now that the old man was talking about his ability to comprehend the rules of nature, Gao Yun immediately thought of the soul trick attribute he had seen from Ying Huang's knowledge.

Hearing this, the old man nodded: "Yes, when you use your soul to create your own domain, you need to bless the domain with attributes, but this attribute is not an ordinary attribute attached to your soul power, but an attribute core that needs to be obtained after in-depth comprehension of the attribute." ”

"Attribute core?" Gao Yun frowned slightly when he heard this.

From the knowledge left by Ying Huang, it seems that this so-called attribute core has not been mentioned, so the biggest possibility is that he has not yet learned this skill.

The demon dragon on the side looked at Gao Yun looking down and thinking, secretly amused, and couldn't help shouting: "Don't think about it, kid, this attribute core is not a cabbage in the market, you can have it if you want to!"

Gao Yun raised his head and looked at the Demon Dragon fixedly: "May I ask the Demon Dragon senior, how did you comprehend this attribute core?"

He was not a narrow-minded person in the first place, and if he knew everything, he knew everything, and if he didn't know, he didn't know.

Even if the other party is not good at speaking, he is willing to ask for advice sincerely, of course, if the other party is not willing to teach, it is another matter.

"Hmph, don't scream so affectionately, I'm not very familiar with you!" the demon dragon flicked his tail in displeasure, glared at Gao Yun, and shouted, "It's nothing to tell you, anyway, with your current strength, it will definitely not work......"

Gao Yun smiled slightly, but directly skipped the opening remarks of the demon dragon and listened carefully to the content of the text behind him.

The demon dragon chattered nonsense again, originally expecting him to be able to advance despite the difficulties, but when he saw that Gao Yun did not react, he still looked straight at himself, looking sincere and taught.

He immediately raised his dragon beard, and secretly thought that this kid's skin was not ordinarily thick, but since he said that he wanted to tell him, he didn't regret it, so he immediately snorted and said in a deep voice: "The soul tricks you have cultivated are actually just some skins, and if you want to exert the true power of each soul trick, it is not how much soul power with attributes is injected, but also your understanding of this attribute." ”

"For example, the body method soul technique you use usually has a wind attribute, or a more advanced one, with a spatial attribute, but in any case, it is to increase the movement speed and dodge ability of the body method. And in order to cultivate the body method and soul technique to the extreme, it is necessary to have a deep understanding of the wind system or space power, to feel their power with your heart, and to make yourself a part of the wind or space and merge with them. If you can comprehend the core of the wind, then you can be as fast as the wind, and if you can comprehend the core of the space, then you can come and go freely in the space......"

"Feel it with your heart and become one with them......" Gao Yun frowned slightly, thinking to himself.

The words of the demon dragon made him suddenly have some vague feelings, but this trace of information was like falling into the clouds and mist, and he could not capture it exactly.

At this time, the gray-clothed old man on the side couldn't stay stunned and reminded: "Have you finished talking, this third layer can't be passed......? According to the cultivation time outside, it is almost equal to an hour's time. ”

The demon dragon was obviously a little jealous of the old man, and when he said this, he immediately stopped talking, but between his expressions, he secretly glared at the old man, interrupting his words, and was quite dissatisfied.

The old man completely ignored the dissatisfaction of the demon dragon, his eyes stared at Gao Yun and said: "The perception of attribute power, especially attribute core, is by no means a day's work, with your current cultivation, you can't even touch the threshold at all, and these are related to the fourth layer of the Netherworld Demon Dragon Technique, you better look at the present." ”

Gao Yun exhaled, it was indeed unrealistic to immediately comprehend the invisible, intangible, and ethereal attribute power now, it seemed that he had honestly tried to pass the trial of the third layer first.

Seeing Gao Yun looking at him, the old man's expression suddenly became stern, and he said, "Before entering the trial, I want to remind you that the difficulty of this test is very high, and even your father, who has already advanced to the Heavenly Netherworld, has not been able to understand it all. ”

"Failed to pass all of them?" Gao Yun suddenly caught a trace of information in the old man's words, and wondered, "What do you mean by not being able to pass all of them?"

"Naturally not, this trial is divided into ninety-nine levels of difficulty, and the meaning of not being able to pass all of them means that you can't pass all the difficulties, but for each time you pass the difficulty, you can get the corresponding reward, and you can get the final reward of this trial. ”

Gao Yun was stunned.

"Ninety-nine floors...... This is too perverted, isn't it? ”

The old man looked at Gao Yun's expression of sticking out his tongue and said with a smile: "What, this is retreating?"

Gao Yun scratched his head and sneered: "That's not true, I just think that there are so many layers in this trial, and it will definitely take a lot of time to clear the customs, so relatively speaking, the cultivation time is much less." ”

Listening to Gao Yun's words, the old man was speechless for a while.

"I don't think about how to pass the guò trial, but I'm worried that the time for cultivation is coming, you kid, you are even more arrogant than your father. Shaking his head, the old man smiled bitterly, "Do you know how many layers of your father, who was a big realm higher than you back then, how many layers have passed through these ninety-nine layers?"

"How much?" Gao Yun asked with interest as he looked at the old man.

Gao Yun knew that in Ying Huang's subconscious, he had always taken Ying Yutian as the goal of his efforts, and he really wanted to know where he had come here back then.

"Twenty-ninth floor. ”

"It's only the twenty-ninth floor?" Gao Yun blinked and couldn't help but take a deep breath.

When Shadow Heaven came to the Treasure Hall back then, it was already the realm of the early stage of the Heavenly Netherworld, and with such a cultivation, he actually failed to pass even one-third of the third-level trial of this Netherworld Demon Dragon Technique, which can only show that the difficulty of this trial is not ordinary!I1387
