30 million points, converted into Huaxia coins, worth 3 billion, please ask a mentor, it is definitely a sky-high mentor.

Throughout the ages, even if Confucius crossed over, he could not get such a high price of tutoring fees.

With the success of the transaction, the system did not live up to the high price of 30 million points, and knew everything about Mu Chen's problems, and she would guide Mu Chen if he had any doubts.

It's just that when teaching, the system will inevitably complain a few words of dissatisfaction.

Obviously, for the value of the existence of the Liuhe Labyrinth itself, she is still very difficult to give up, in order to let Mu Chen know the difficulty and retreat, obediently let go of the Liuhe Labyrinth, she opened her mouth at every turn to sarcastically mock Mu Chen.

"Oh, Mu Chen, you're really stupid, you don't understand such a simple question. Magic crystal, to put it simply, is a spirit stone, you must know that spirit stones are also divided into two types: attribute and non-attribute. In the East, attributeless spirit stones are more precious, because they are the best source of spiritual power that cultivators need. As for the spiritual consciousness with attributes, cultivators basically don't use it for cultivation, and most of them are only used to arrange formations!"

"However, the cultivators of the West are different from the cultivators of the East, and the cultivators of the East use spiritual power as a medium to mobilize all kinds of forces of gold, wood, water, fire, and earth between heaven and earth for my use, exerting supreme power. As for Western cultivators, as you said before, they are stupid, they don't use spiritual power as a medium, but forcibly extract power, so what they use is basically spiritual stones with attributes, also known as magic crystals. As long as you absorb the power inside, you can continuously improve your cultivation, so you understand?"

"And here, although the Eastern and Western formations have similarities, they are not a school after all, why don't you even know this? The power of this Afterlife Sword Diagram is naturally because it can extract the power of all spirit stones and turn them into attacks. And the Western formation is not carved formation, on the contrary, their divine patterns are engraved in the spirit stone, and it is directly used to extract the power of the spirit stone itself, which is a bit similar to the art of practicing talismans in the East, I don't understand, you are so stupid!"

"Oh, and here, why don't you even understand such a basic thing, do you have to let me explain every problem to you! If this goes on for a long time, even with my guidance, you won't want to open the Liuhe Labyrinth in less than half a year to a year. Mu Chen, I advise you to transfer the Liuhe Labyrinth to me, let's discuss, I lose a little, three or seven points, how about I seven and you three?"

Faced with a wordless complaint from the system, Mu Chen was unheard.

Anyway, after she complains, she always gives the answer.

As time slowly passed, Mu Chen also understood that in the past, whatever was exchanged, the system would be reflected in her mind in the form of memory, but this time, she was unwilling to reflect the method of cracking the Liuhe Labyrinth into her memory, which was obviously a treasure of the pit that turned the corner.

In the face of the stubbornness of the system, Mu Chen was on a par with her, and he would not let out the Liuhe Labyrinth even if he was killed.

As a result, the first cold war between the system and Mu Chen began, and although they have been in communication, they have not given up the idea of the Liuhe Labyrinth.

Gradually, most of the day passed.

At noon, the system finally softened: "Mu Chen, you are ruthless enough, you would rather die than transfer the Liuhe Labyrinth now, right?"

Mu Chen grinned and said, "That's smart!"

The system was speechless and said: "Forget it, I'm too lazy to fight with you, and I'll remind you again, although this Liuhe maze is worth a lot, after you get it, it will also have unspeakable benefits for you, but it's more of a drag." Think about it, if you are not willing to give up, I will teach you the basics of the formation first, and then we will slowly study these big formations!"

Mu Chen raised his eyebrows and said with a smile: "Give up so soon?, but your agitation method is useless to me, hundreds of billions of treasures, even if you hold it in your hand and appreciate it, you will never transfer it!"

"You bastard!" The system was furious, and then said: "Forget it, one billion points, exchange for the formation foundation Daquan, and help you advance to the title of all-round junior formation mage!"

As he spoke, the system turned into anger, but apparently gave up the battle for the Liuhe Labyrinth. Of course, it's okay to give up the competition for the Liuhe Labyrinth, but if you don't take the opportunity to extort a sum, it's obviously not the character of the system.

"Deal!" Mu Chen hesitated for a moment, he also wanted to crack the Liuhe Labyrinth as soon as possible. Although one billion points is a lot, it is not worth mentioning compared to the value of the Liuhe Labyrinth of 100 billion.

As soon as Mu Chen's voice fell, the points on the system page immediately shrank.

The two and three billion points that were only collected today were exchanged for six necklaces and cost six billion, and then they were exchanged for systematic counseling, which cost thirty million, and now they are exchanged for the title of all-round junior array mage, which costs one billion. Of the 23 billion points, there are only more than 15 billion left in the blink of an eye.

However, as soon as this point was deducted, a huge memory immediately hit Mu Chen's mind.

"That's right, I said system, although you are sometimes a little unkind, comparable to a vampire, but I have to say that it is quite fair to make a deal with you!" Mu Chen closed his eyes, and with his strong spiritual power, he quickly digested the memories in his mind, and couldn't help but admire.

It is said that you get what you pay for, although there are a lot of billion points, but in his mind, he has the memory of dabbling in each formation knowledge, and Mu Chen still feels that it is worth it.

"I'm very fair, although I often ask you for points, but the value of each exchange is the same!" The system snorted very dissatisfiedly: "One thing you have to be clear, although the formation is not a necessary knowledge for cultivators, but the formation mage is the most popular profession in the cultivation world." Whether it is refining weapons, alchemy, or even refining talismans, refining puppets and the like, formation knowledge is indispensable. ”

"Don't look at you as a junior formation mage now, but after all, there are two words of omnipotence, basically you know all types of basic formations, once you use these formation knowledge to earn commissions, one billion points, it won't be long before you can earn them back!"

Mu Chen nodded slightly and did not refute. If he had heard these words before, he would have felt that the system was selling melons and boasting about himself.

But at this moment, after accepting that memory, he not only knew a lot about the formation, but also had a little understanding of the knowledge of refining weapons, refining talismans, alchemy, etc., and he knew very well how much benefit this memory could earn for himself.

"No wonder you refused to tell me the method of cracking the Liuhe Labyrinth before, the price of the knowledge of the Great Array of the Liuhe Labyrinth shouldn't be cheap, right?" Mu Chen said.

"Isn't this nonsense, if you want to arrange such a big array, you also need the ability of a high-level array mage, I will tell you the method of cracking the Liuhe Labyrinth Great Array, isn't it equivalent to teaching you how to set up the array? And to teach you to set up the array, you need to give you the corresponding array mage ability, worth hundreds of billions is not too much, right? And even if I hide something and don't let you become a high-level array mage, but for you to learn this big array, it will take at least four or five billion points. You want to win more than 10 billion points, how can there be such a good thing in the world!" The system was speechless, and deeply despised Mu Chen's ignorance.

Mu Chen gasped, and at this moment he really knew how popular the array mage was.

In this Liuhe labyrinth, the materials arranged are no less than 100 billion points, and the layout of the formation also needs 100 billion points, and its value is simply incalculable.

Just as he had seen the value of the pill before, Mu Chen once again decided that in the future, he must study the way of formation and the way of alchemy.

Just as he was about to speak, suddenly a mechanical voice sounded.

"Ding, the employer confirms the order!"

"Ding, congratulations to Mu Chen for successfully completing the task of the full-time housekeeper system and receiving super ten-star praise!"
