Xu Zhifeng knew that this was indeed the case.

This is still said to have been bought from Dongchengfang City.

If you tell the old man that this was given by Ding Song, then the old man Gan will definitely not hesitate to confiscate it directly.

He will decisively decide that it is Ding Song who wants to kill Xu Zhifeng.

So this can't be said that the old man is cheating, he is also very kind, and he doesn't want to watch the genius student cut off his future.

Xu Zhifeng hurriedly held the box with both hands and didn't accept it, "Hey no, if it's really necessary on the boss's side, I can go to him myself." But I'm really interested in this Void Lead, Dean Gan, you can take a look?"

Old man Gan shook his head firmly, and continued to drag the box into his arms, "How much do you buy? I'll give you ten times!

"It's not a matter of money! The Void Guide was created by the great master Void Daoist four hundred years ago, even if I don't learn it, it should always have some reference value. ”

Gandev's hand paused, "Void Daoist?"

"Seriously!"

"Then I'll see if it's true. As far as I know, what this Void Daoist is practicing is an extremely rare extreme type Xuan Armor, which is known for its myriad variations. The exercises he created may really suit you. ”

Xu Zhifeng was overjoyed, it seems that Old Man Gan knows more about the Void Daoist, of course, it may be that Ding Song didn't say it all, after all, Ding Song doesn't know about Extreme Serie A.

He asked, "How does the changing extreme type compare to my extreme Serie A?"

Gandev shook his head, "In terms of subtlety and profundity, it is naturally inferior to you." But Void Dao was an A-level peak powerhouse before his death, and his control and cognition of Xuanyuan is not something you can imagine. Okay, I'll see if it's genuine. ”

In other words, Gandev finally opened "Void Introduction".

As he moved, a gray black light floated out of the book and gently fluttered onto the old man's face.

Gandev's face glowed with a milky white sheen, and the black light swept away and dissipated into the air.

"You didn't read this book first, it was the right choice, this is indeed a fairly high-level exercise, and it has the divine effect of guiding cultivators on its own. With your understanding, you will really learn it as soon as you open it. What you said is true, "Void Introduction" is from the hands of the Void Daoist. ”

is worthy of Dean Gan, his knowledge is wide, and he made a conclusion at a glance.

Xu Zhifeng nodded, "That's good." ”

"Don't interrupt, I'll keep watching. ”

The old man raised his hand.

Immediately, he turned the pages with a clatter, and after about an hour, he put the book down first, and then took the Chaos Stone next to him and looked at it for a long time.

Putting down the stone, he looked up at Xu Zhifeng, his gaze was a little complicated.

"Dean Gan, what's wrong?"

Old man Gan coughed lightly, "I told you about the exercises and auxiliary references, right?"

"Well, I know that the Xuan Li in the Xuan Liquid needs to go to the reference material for a while in order to absorb it faster and more efficiently. The reference of the Void Quote is the Void Stone, right?"

Gandev nodded, "Yes, but it's not right either. Let me start by telling you about the merits of the Void Channel. It has taken the ever-changing strengths of the Void Dao people to the extreme, with extremely strong inclusiveness and absolute balance, these two unbelievable qualities. ”

"It also has no obvious strengths in fighting, lacks explosiveness, and basically no one practices the comprehensive Xuanshi, dislikes its low energy efficiency ratio, and other types can't practice. ”

"But your Extreme Serie A is all about change, and the Void Guide is simply tailor-made for you. Instead, you can turn absolute equilibrium into absolute single lethality, which can multiply the power of Extreme Serie A. ”

"Also, it can be an eclectic mix of other exercises. As long as you are willing to try, willing to work hard and not afraid of death, you can constantly learn from other exercises and make up for each other's weaknesses. ”

Xu Zhifeng was shocked, "There is still such a thing?"

"It's theoretically impossible to achieve, but this impossibility is broken by the Void Dao people with amazing wisdom, and it's really an amazing and unsolvable solution. ”

The old man boasted the advantages too hard, so that Xu Zhifeng had the illusion, Ding Song's gift is really so heavy?

"Okay, after the advantages, I'll talk about the disadvantages. As we all know, the more real and grand the reference, the better. Such as the earth, the sun, the moon, all things, living beings, rivers, mountains, fire, water, light, wind, ice, only you can't think of it, no one can't use it. ”

"But compared to all these things, the void still seems too ethereal, formless, colorless, and elusive. So it's very difficult for you to use the void as a reference, you first have to find a way to make Xuanyuan sustenance in the void, and then you have to extract Xuanyuan from the void. Can you imagine that picture?

Old man Gan said in a heavy tone.

Xu Zhifeng thought seriously for a long time and nodded, "It's difficult." But isn't there a Void Stone?"

"Yes, with your talent, it's no problem to practice. You can definitely master it with the Void Stone. But even if you can simulate the birth and death of the void in the Void Stone, the loss rate of Xuanyuan will be very high. This will be much higher than the loss rate of ordinary exercises, plus you have now cultivated a special type of Xuan Armor, your promotion consumption is already much higher than that of ordinary Xuan Shi. ”

Xu Zhifeng nodded, "That's true." ”

"One more point. Gandev picked up the Void Stone, "You said this Void Stone is tangible or invisible?"

Xu Zhifeng replied: "Of course it is tangible. ”

Gandev: "Since it is tangible, it is not the most suitable reference for the void in the first place, but only a substitute for the next best. This will further increase your Xuanyuan churn rate. ”

"Thirdly, with the size of this Void Stone, it can only support you to the E-level high level at most. Where are you going to find this thing in the future? The Void Stone is indeed not expensive, but that is only because it is of too little use, and there are so many people in the world, and this is not something that can be bought with money!"

"Fourth, judging from my experience, you use the Void Stone as a reference for sustenance, even if you can really find a sufficient amount of Void Stone, this substitute can still only support you to the C level. This is the most important point. ”

This series of hammers hit Xu Zhifeng full of bags.

The pros and cons are summarized below.

Advantages: The A-level boss's dying achievement represents his highest wisdom crystallization and lifelong learning, and it is completely in line with the extreme Serie A, and it can also be compatible with expansion.

Disadvantages: one, two, three, four, one pit with another.

The first pit and the second pit are acceptable, but the consumption of Xuan liquid is larger, and the spore clones can hold up when they develop.

The third pit is also acceptable, or wait for the spore clone cow to get up and copy the Void Stone on its own.

But this fourth pit is the real bottomless pit!

"In short, you still have to think about it and decide for yourself whether to cultivate or not. If you can jump out of the shackles of the Void Stone after the C level and figure out how to really use the Void Channel, then what awaits you will naturally be a flat river. In my opinion, it can't be, it's really impossible. Wait a minute, I'll call and ask. ”

Gandev hummed for a long time, hung up the phone, and rolled his eyes.

He asked again, "Did the person who sold you this secret book tell you that he got it from the Void Dao people's underwater cave mansion?"

Xu Zhifeng nodded, "Yes." ”

Gan Defu stretched out five fingers, "So far, at least fifty caves have been discovered by the Void Dao people, and there are at least fifty Void Guides circulating in the world. It seems that he really hopes that future generations can practice this practice, which only exists in theoretical possibilities. But in fact, no one has ever been able to practice, even if they practice reluctantly, and later when they see that the situation is not good, they will revise it early, so as not to be overwhelmed. ”

Xu Zhifeng glared, "Ha? Okay, I know, thank you Dean Gan, I'll go first." ”

Now he understands, no wonder the inheritance of the A-level boss is only sold for 100 million, as if it was given away for nothing.

With a worried and hesitant mind, Xu Zhifeng went back to the villa directly with the suitcase, and even missed the first class of the academy in the afternoon.

skipped class in the first class of school, and only he, the man from the tutor's family, dared to be so arrogant, and he couldn't say half a sentence to others.

People go home and open a small stove alone, and make up for it in bed until their physique can't keep up!
