Chengying took the ring to check it, and was surprised to find that the space of the ring alone was ten cubic meters, which was much larger than the antique spirit guides circulating on the Douluo Continent.

He was not easy to verify the authenticity of the books in it, but it seemed that they were installed in a hurry, and there was no time to fake it. Thinking of this, Chengying felt a burst of joy in his heart. In his opinion, the soul mentors absolutely It is embarked on an evil road.

　　 The soul guide should be divided into one, two, three, and four levels? What kind of brain-dead system is this? Perhaps the other party is not brain-dead, but its purpose is different from Chengying's. After all, from the point of view of maintaining the status of the soul teacher, the soul guide grading is not only not brain-destructive, it is even a genius idea.

　　 But what Chengying wants to say is that all the technologies that are not put into industrial production are hooliganism. The Soul Guidance Device has clearly reached the level of science fiction in many aspects. As a result, Sun Moon Continent is still using a carriage?

Not to mention anything else, many small parts that are difficult to handle in mechanics can be replaced by Soul Guidance Device. It doesn't need much destructive power. As long as it can move, it can be driven by a first-level Soul Power, and you can install it at the lowest level. The baby bottle, which is the soul guide that stores soul power, can run for a few weeks. As a result, the soul teacher has to develop this thing into a weapon, and he also needs to be one person to prevent similarities and large-scale production. It is really smart operation. .

　　 Chengying was just talking about it casually. There is no doubt that the advanced Soul Guidance Device will improve the personal combat effectiveness, but Chengying doesn't plan to invest too much energy, just spend money to buy that kind of thing.

　　 On the contrary, something more basic is more worthy of study. It's like your opponent is holding a Level 9 Soul Guidance Device, and you are guarding the tractor field, with three thousand armored divisions by your side, and the tractor field can continue to produce. Who can beat whom?

There will be time to read these books slowly in the future. Compared with the knowledge inside, the most urgent thing is to purchase a large amount of rare metals. On the Douluo Continent, this thing is very scarce. There is not enough rare metal. Don't even think about making a soul-guided ray gun. come out.

Chengying picked and picked in the space ring, and finally found a book introducing rare metals for a long time. At a glance, there are mithril, fine gold, red copper, and meteorite iron from the sky. Look at the prices behind. Quite scary.

Except for the more basic steel or copper, tin and lead, the price of this kind of serious metal is comparable to gold coins of equal quality. Fortunately, there are also cheaper inferior rare metals, and even the most inferior ones are OK. Man-made, it is still uncertain in this respect, but no matter which kind, even if it is 100 times the quality of gold can be exchanged for the most precious type, Cheng Ying has to take some back.

　　 "What are you looking at? So fascinated?" Bingdi jumped up, snatched the book from Chengying's hand, and then found that he didn't recognize the words on it.

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

　　 "Aren't you rich? The gold you brought is piled up into hills, can't you still buy the rare metal you want?" Bingdi tilted his head.

"It's not a question of enough! Many of these metals are more valuable than gold. I can't get much of my gold together, and wouldn't it hurt to use my own money?" Cheng Kageichi seriously said something shameless.

　　 "What? You don't need your own money, can you use someone else's money to buy it? Isn't that just a snatch? Why do others let you **** it?" Bingdi held the book in his hand solemnly, as if she could understand it.

Cheng Ying shook her head, picked up the book in Bingdi’s hand, dropped one of them, and put them back in her hand: "Little fool, the books are all upside down! Naturally, I can’t steal money from someone else’s. Yes, but why not let them give me the money themselves!

　　 Didn’t I say that I would teach you a lesson on the Sun-Moon Continent as a testing ground? It happens to take this opportunity to let you see the essence of human nature. "

Cheng Ying turned her head and spoke earnestly and preaching, like a famous teacher with both ability and political integrity, but, who the teacher is, all the disciples have a compelling number in their hearts. To use a more concise description, it is not a good bird. Son.

　　 "Teacher, didn't you really cheat money by going to class because you can't bear your own gold?" Meng Shu always likes to tell the truth, so he is the most often beaten...

This time there is no exception. Holding the big bag covering his forehead, Meng Shu followed Chengying to a crowded building. Everyone here was holding cards made of rare metals with corresponding anti-counterfeiting marks. And numbers, one by one queued up and operated on the window.

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

　　 "It should be a bank." Among the disciples, the most knowledgeable Tang Chen frowned, "On the Douluo Continent, some large merchants with business avenues all over the mainland will provide similar services.

People hand over the money to them, and then they can get a voucher, which can also be held at a long distance and exchanged for money in the hands of people in the chamber of commerce~lightnovelpub.net~ saves shipping coins The trouble, although some handling fees need to be paid, but it wins in safety. "

"Eh? Didn't the teacher want to spend her own money? Why did she still have to come to the bank to save money?" lock up.

"Because this is different from a bank, I prefer to call it a bank. Not only do they don't charge fees, but they will give depositors interest. That is to say, even if you don't care, the money that exists here will increase a little bit." Chengying smiled.

　　 The emergence of banks and the use of interest to attract people to deposits all means one thing, that is, someone has realized that money can make money. In this way, many methods have room for operation.

　　 "I see! The teacher is going to use interest to buy rare metals, so I don't spend my own money!" Meng Shu's eyes lit up.

Snapped!

　　 Chaotianxiang slapped him on the head: "You don't need to say some silly things from your heart to prove yourself. Everyone knows that you are mentally retarded."

"Don't be so strict with him." Chengying stopped Chao Tianxiang and continued to scold Meng Shu: "Without such a person as him, how can I still make money for my teacher! With the convenient transaction channel of the bank, some dirty tricks can be used. Have fun!

How about this! During our time in line, let me tell you a story! This is also related to our plan to make money in the near future, see if you can hear something. "

　　 All the disciples heard the words, their eyes lit up, Chengying's story is always so interesting but full of philosophies, even the Ice Emperor blinked his big eyes and prepared to listen to the story.
