Returning to the academy, Lei Zhe and the others traded all the materials they obtained into credits, except for the things that were useful to themselves.

And among the three, who has the most credits, it is not Lei Zhe, who has contributed the most in the secret realm and serves as the captain.

It is true that Lei Zhe, as the captain, occupies the largest share of the harvest of the entire secret realm, a full forty percent. However, Lei Zhe did not exchange the magic crystal for credits, so he got the most gains, but he was the one who held the least credits now.

Now Lei Zhe is no longer alone, with three summoned beasts, Laura, Denisa and Mana, each of whom needs magic to survive and grow. If they rely on food alone, they can only maintain normal life activities, and if they want to become stronger, they can only keep feeding the magic crystals.

If it weren't for the fact that Lei Zhe himself also needed to use the credits, I am afraid that Lei Zhe would have exchanged all his credits for magic crystals early in the morning to promote the growth of Laura and the three of them at one time.

Accompanied by entering the secret realm once, everyone has more or less small savings on hand, even those who were originally quite poor.

The college seems to have deliberately put the vast majority of students in a state of "lack of money", and after a secret situation, the pace of teaching has been increased a lot, and many teaching contents require students not only to have their own understanding, but also to require extensive insights and knowledge, which can only be learned by themselves from the central library of St. Black's Union.

“…… The so-called alchemy is a method of imprinting a rune array composed of runes on a specific body with materials to create alchemy props. To make a successful alchemy prop, you need three prerequisites: a carrier, two rune arrays, and three stable trigger mechanisms. ”

“…… For example, the magic sword in my hand can also be said to be an alchemy prop, in which the carrier is this sword, which is made by an ordinary blacksmith, and can only be regarded as a fine product! But on my hand, according to the condition of the sword, I branded it with two solidification spells of acceleration and reinforcement, as well as a triggerable level 3 fire magic fire wall technique, which melted the magic crystal into magic crystal liquid to form an artificial vein that could allow the magic power to flow, and linked the magic rune solidified with the sword......"

“…… A true rune master is like a sculptor, and the carrier more or less affects the quality of the final product, but what really determines the success of the alchemy item is its unique rune array inlay technique and the efficiency of the magic-driven trigger mechanism! ”

……

After a class, the key techniques were not handed over, and the professor of the Alchemy Academy popularized the core of alchemy for everyone, theoretically speaking, as long as he comprehended these three core points, then even if he was not an alchemy master like Dean Kelly, he would be an alchemy master in the Deland Continent.

But there are many people who know the key points of alchemy, but they really want to really master these three points, not to mention that Lei Zhe has become a student of Dean Kelly, even if Lei Zhe really practices under Dean Kelly's teaching for 10 years, he may not be able to become an alchemy master like the other party.

If you want to really grow in alchemy, in addition to mastering the key points, you need to learn a lot, and it is best to be able to master mastered the master-level techniques, so as to constantly create your own alchemy methods according to your own situation. And if you want to learn, there is no other way than to pay for it to study by yourself in the vast alchemy books in the library.

Walking into the central library of the academy located in the Demon Court, Lei Zhe suddenly felt the sacredness of what is called knowledge, and the moment he walked into the library, even a rugged person who originally liked to speak loudly would unconsciously lower his voice, and the whole person would become restrained.

The entire library is divided into up to hundreds of areas according to the type of books, and even the same area will be restricted to different areas according to the status level, such as the freshman who has just entered the academy has the authority of level 1, and the special enrollment of Lei Zhe who enters the academy has a level 3 authority comparable to that of graduates of the outer courtyard.

Level 1 access is limited to the library where you can only access the books in the Level 1 area, and you are not allowed to borrow them and you will have to pay a fee to view their contents. Level 2 permission is the ability to borrow books below level 2 and can borrow books below level 2, and level 3 permission is the ability to read 10% of the collection below level 3 free of charge, and can confirm whether you meet your requirements by flipping through some of them.

As for the higher authority above this, only the students of the Inner Academy, as well as the professors and deans of the college, can have it.

Just like Lei Zhe wants to borrow a basic guide to alchemy in the level 1 area, although it is the most basic collection of books, it takes 1 credit for every day of borrowing, and the magic book that teaches elemental magic is even more amazing, even if it is only a magic book of level 1 magic, the number of credits required to borrow it for a day is more than 100, which is not affordable for ordinary people at all, and the credits required to read in the library are only one-tenth of the extent of borrowing, but the library is not better than the outside, causing some movement to make you feel better.

The collection of books that Lei Zhe needs to borrow is not as good as that of ordinary people, most of the books in the level 3 area are unique books that are difficult to find in the outside world, and at the same time, they are recorded in the magic book made of alchemy, even if they are thousands of years old, they will not be destroyed, and even with images and audio, borrowing a book of this level will make Lei Zhe feel painful, and what does Lei Zhe need more than one?

The magician Slimemana needs more books on magic, while the swordsman Slime Dinisha needs a collection of books on swordsmanship, and even Lei Zhe himself needs more secrets about alchemy and runes, and the three of them together have consumed the tens of thousands of credits that Lei Zhe has obtained in just over a month.

"It's a real headache, the credits are the same as money, I thought I had become a 10,000 yuan household, how long has it been since I was beaten back to my original shape......" Click on his student ID, with the input of magic Lei Zhe can see it clearly, his credits are only 1200 points, and it will be a matter of a day or two if these are really used, "I want to make money, make a lot of money!" Mana, how's it going? Have faith? ”

Regarding the content of making money, Lei Zhe had an idea after obtaining the wizard Slime Mana, and in the past month or so, in addition to the most credits he consumed, the real bulk of it was all invested in Mana.

Her whole body glowed with the glow of the flow of sea blue|magic, Manna jumped onto Lei Zhe's shoulder, and then arched her body against Lei Zhe's face, letting out a grunt of confident cheers.

The power of the scroll generation technique LV.1 is waiting to be tested, and with the power of the ability rental LV.1 granted by the system, Lei Zhe can also have the scroll generation technique, which is equivalent to having two alchemists who can generate magic scrolls in large quantities at the same time.

"But...... It's difficult for a good woman to cook without rice, let's see how much money can be made of these more than 1,000 credits, let's study the market first, don't lose all the money at once. ”

Although it is also a level 1 magic scroll, the popularity of level 1 magic scrolls varies, and if you make the wrong magic scroll, it will not sell at all.
