"You''re wrong to say that! It''s your wish to do business. Since kerosene is better than candles, it''s only natural that my kerosene can be sold. "

    Although the soul master ability on Douluo continent is strange, it can be said that the development of science and technology still stays at the level of the middle ages. Kerosene lamps are magical for aristocrats like night. In particular, they can adjust the brightness, which makes him very interested.

    "But I''m more interested in your kerosene. As for this lamp, I can''t earn much."

    "It''s hard to do! The technology of refining kerosene is related to many other more important technologies. If you have tens of millions of gold soul coins, I can sell them to you, but ordinary people can''t afford so much money. Kerosene alone is not worth so much.

    If you only buy the technology of the lamp, I can sell you 100000 gold soul coins. If you can''t make this glass cover, you can outsource it to my glass factory and guarantee that it is 30% lower than the market price. " You know, glass is a work of art in this era. In contrast, glass can only be regarded as daily necessities, and a low 30% can also make a lot of money

    "You have to drink all the soup!" In spite of this, the photographer could see the other party''s intention, so he continued:

    "I''m honest. We all earn money. Kerosene lamp can only be regarded as an appetizer. Look at so many things on my counter, I don''t worry about no chance of cooperation in the future, do I?

    In this way, if you feel bad, I''ll give you another tip for free. Didn''t you say that candles still need to be cut before? I have a way not to cut candles! " Then he turned his head and said, "Bo! Bring me a candle for the teacher. "

    Hearing this, Dugu Bo hurriedly went to his desk and brought a candle. After a few days of contact with Chengying, he really admired his master. Chengying said that he taught him the most basic things, but Dugu Bo knew that the more basic things were, the more important they were. Dugu Bo benefited a lot from both cell theory and material atom theory, Also more and more respect for the film.

    Chengying took the candle and lit it in front of the night. Then the night was surprised to see that with the burning of the candle, the wick spread into three parts by itself, and then burned into ashes. Just rubbing the wick into three strands can avoid cutting the candle.

    The principle is so simple, but no one can think of it before seeing it with his own eyes.

    "As you can see, it''s actually that simple. I call this power of change technology, and all the things I sell are new things that can change people''s lives." The photographer blew out the candle and raised his head to indicate other goods on the counter next to him.

    Night also understood at this time that what the studio sold was not any commodity, but what he named technology behind these commodities.

    "I have already received your gift. If I don''t buy it again, I will become a villain. I will send 100000 gold soul coins as soon as possible. What about the drawings?"

    When the photographer heard the speech, he took out a piece of paper from the counter and drew the standard ruler and gauge. After only a moment, he drew the three views of each part of the kerosene lamp, marked the scale, and the structure was clear at a glance.

    He is not worried about the other party''s default. The kerosene lamp is just one of many small things in his mind. If he tries to find out a person with it, it won''t hurt at all.

    "Your painting is very interesting. Although it''s the first time I''ve seen you, I can see it at a glance. But it''s much easier to understand than those craftsmen''s inexplicable drawings. Is this what you call technology? "

    "Yes! The three views are only the basis of the drawing. " When he thought of all kinds of homework in engineering drawing class in college, he had a feeling that he couldn''t bear to look back.

    "I hope there will be opportunities for cooperation in the future!" The night held out his hand, and Chengying also held out his hand and said, "I still have a few treasures of the town store that haven''t been sold! I hope they can fall into your hands. "

    "The treasure of the town store you said must be a good thing. By the way, I haven''t asked your name yet."

    "Background."

    "Brother Cheng said goodbye!" After that, the night rolled up the drawings, ordered a few words to the domestic servant outside the door, and said goodbye to the photographer.

    That afternoon, a carriage pulled 100000 gold soul coins and came to the door of the shop. It was early heard that the ice emperor who recorded 100000 gold soul coins was waiting at the door. Seeing the golden hill pulled by the carriage, he immediately jumped into the pile of gold coins.

    "Mine, all mine!"

    However, before she could enjoy the feeling of being surrounded by gold coins, she was held out by the shadow under her arm: "I told you how many times, don''t play with money. It''s very dirty for anyone to touch."

    "I want you to take care of it. Your money is my money. I can play if I want!" The ice emperor opened his teeth and claws. However, he was in a hurry. When he was picked up by the shadow, his feet were off the ground. He couldn''t break free without exposing his strength.

    "Gold coins! In fact, that''s what happened. In the future, you will understand that a stack of paper or even a string of numbers can make you more excited than now. " Chengying also noticed that there is no systematic bank in Douluo mainland, which is also an opportunity for him.

    "Are you kidding? How can paper have gold coins! I don''t believe it! " The ice emperor looked unhappy when Dugu Bo moved a large box of gold coins into the shop.

    Chengying rubbed her little head and said with a mysterious smile, "you''ll understand later. At that time, I promise you''ll laugh at a string of zeros."

    Then he took the ice emperor back to the shop. The servant in charge of giving money didn''t doubt that he was just a wayward little girl. There were many such girls in the big family.

    "Hello! I said, "Xiaoying, are you really making these strange things to make money?" The ice emperor, who was held back to the shop, licked a strawberry popsicle and asked suspiciously.

    "Not all!" Chengying picked her up in the ice emperor''s resentful eyes, put her on his legs and held her in his arms like a pillow.

    "It''s mainly for a more comfortable life! Just like the ice cream in your hand, many interesting things have not appeared in this world. If you want to enjoy them, you have to create them with your own hands. "

    "We have ten thousand years, which is more than a hundred times that of ordinary people. Wouldn''t it be a pity if it passed quietly?

    Would you like to go back to the time when there is no ice cream, no cooking, no story and no lantern? "

    The ice emperor, who was held in his arms by the film, thought about that kind of life and quickly shook his head: "no, it''s too boring. Now I don''t even want to go back to the far north."

    "Yes! This is my purpose! Let me tell you a story! " Chengying smiled cunningly.

    The ice emperor who listens to the story every day nods and wants to know what the film will tell her.
