Chengying took the ring and checked it. She was surprised to find that the space of this ring alone was ten cubic meters, which was much larger than those antique soul guides spread on Douluo continent.

    It''s not easy for him to verify the authenticity of the books inside, but it seems that they are all packed in in a hurry. I don''t think there''s time to fake them. At the thought of this, Chengying''s heart is filled with joy. In his opinion, the soul mentors are definitely on an evil road.

    The soul guide is divided into one, two, three and four levels? What kind of system is this? Maybe the other party is not brain disabled, but it is different from the purpose of the film. After all, if you maintain the status of soul mentor, the classification of soul guide is not brain disabled, but even a genius idea.

    But what Chengying wants to say is that all technologies that are not put into industrial production are playing hooligans. It is clear that the soul guide has reached the level of science fiction in many aspects. As a result, the sun moon mainland is still using carriages?

    Not to mention anything else, many small parts that are difficult to handle in mechanics can be replaced by soul guides without much destructive power. As long as they can move, they can be driven by first-class soul power. Just install the lowest level milk bottle, that is, the soul guide that stores soul power, and it can run for a few weeks. As a result, the soul mentor has to develop this thing into a weapon and look like a person, It is really wise to put an end to the same and large-scale production.

    It is beyond doubt that the advanced soul guides can make complaints about personal combat effectiveness. But the shadow does not intend to put too much energy into it.

    On the contrary, it is more basic and worth studying. It''s like your opponent is holding a level 9 soul guide, while you are guarding the drag airport. With 3000 Armored Divisions around you, the drag airport can continue to produce. Who can beat who?

    After reading these books, I have time to read them slowly. Compared with the knowledge in these books, the top priority is to buy a large number of rare metals. On Douluo mainland, this thing is very scarce. There is not enough rare metals. You can''t make a soul guided ray gun.

    Chengying picked up in the space ring. After a long time, she finally found a book about rare metals. At a glance, there are secret silver, refined gold, red copper, tianwai meteorite and so on. Looking at the price behind, it is also quite frightening.

    In addition to the basic steel or copper, tin and lead, the price of this serious metal is comparable to that of gold coins of equal quality. Fortunately, there are some cheap low-quality rare metals. Even the filmmaker suspects that the worst one can be man-made. This is uncertain, but no matter which one, even gold of 100 times the quality can be changed to the most precious type, You have to take some back, too.

    "What are you looking at? So absorbed? " The ice emperor jumped up, grabbed the book from the photographer, and then found that he didn''t know the words on it.

    "I''m looking at the price of these rare metals! It''s too expensive. I don''t know how much it will cost to buy it back! " Chengying shook his head and sighed.

    "Aren''t you rich? The gold you brought is piled into a hill. Can''t you buy the rare metal you want? " The ice emperor tilted his head.

    "It''s not enough! Many of these metals are even more valuable than gold. I can''t exchange much for those gold, and won''t it hurt with my own money? " Chengying said quite shameless words in a serious manner.

    "What? Don''t use your own money, do you buy it with other people''s money? Isn''t that robbery? Why should others let you rob? " The ice emperor solemnly held the book in his hand, as if she could understand it.

    Chengying shook her head, picked up the books in the ice emperor''s hand, dropped them all, and stuffed them back into her hand: "little fool, the books are reversed! I can''t steal money from others, but why don''t they give it to me by themselves!

    Didn''t I say I would give you a lesson on the sun moon continent as the test ground? Just take this opportunity to let you see the essence of human nature. "

    Chengying turned his head and preached with great sincerity. It was like a famous teacher with both moral integrity and talent. However, the disciples had a forced number in their hearts about who the teacher was. In a more concise description, it was not a good bird.

    "Teacher, don''t you really cheat money by taking advantage of class because you don''t want your gold?" Meng Shu always likes to tell the truth, so he is also the most beaten

    There is no exception this time. With a big bag on his forehead, Meng Shu followed the film to a crowded building. Everyone here took cards made of rare metals with corresponding anti-counterfeiting marks and numbers, and lined up at the window one by one.

    "What is this?" Meng Shu rubbed the bag on his head and asked in doubt.

    "It should be a bank." Among the disciples, Tang Chen, the most knowledgeable, frowned and said, "on Douluo mainland, some large chambers of commerce with business routes all over the mainland provide similar services.

    People give money to them, and then they can get a voucher. In a far place, they can also take this voucher and re exchange it into money in the hands of people in the chamber of Commerce, which saves the trouble of transporting money. Although they need to pay some handling fees, it is better than safety. "

    "Eh? Don''t teachers want to spend their own money? Why do you have to come to the bank to save money? " Posisi was blindfolded by the teacher''s operation. She was one of the few people who followed the idea of filmmaking, so she was even more blindfolded.

    "Because it''s different from banks here, I prefer to call it banks. Instead of charging handling fees, they will give interest to depositors, that is, even if you don''t care, there will be more money here." Chengying smiled.

    The emergence of banks and the use of interest to attract deposits all mean that some people have realized that money can generate money. In this way, many means have room for operation.

    "I see! The teacher wants to buy rare metals with interest, so he doesn''t spend his own money! " Meng Shu''s eyes lit up.

    Pop!

    Chao Tianxiang slapped him on the head: "you don''t have to say some stupid words from your heart to prove yourself. Everyone knows that you are mentally retarded."

    "Don''t be so hard on him." Chengying stopped Chao Tianxiang from blaming Meng Shu: "how can I make money as a teacher without him! With the convenient transaction channel of the bank, some dirty tricks can be played!

    All right! While we are waiting in line, let me tell you a story! This is also related to our money making plan in the near future. Let''s see if you can hear something. "

    When the disciples heard the speech, their eyes lit up. The story of the film is always so interesting but rich in philosophy. Even the ice emperor blinked his big eyes to listen to the story.
