After so many days, there was no sign of awakening golden finger. He had no choice but to recognize the reality. Everything was realized by his own strength.

    Having read two Douluo books, he knows very well that tianmeng is a thoroughly weak chicken. In the end, he has no combat effectiveness. He can''t fight for 100000 years for millions of years. It''s hard to expect his cultivation to become stronger.

    However, he also wanted to take the film. He didn''t have anything else, but he had a lot of time. In 10000 years, he gave the soul beast the most, that is, to cultivate and become stronger. But if he gave it to him, it''s still no problem to build several aircraft carriers, not to mention GAODA or interstellar warships.

    Backed by an aircraft carrier battle group, even if a soul beast dares to fight for 100000 years, he can fight. He doesn''t even know him.

    Therefore, the studio set up a small shop in Tiandou City, starting with the simplest things. A set of industrial system can not be supported by one person, but a set of basic scientific enlightenment ideas can be compiled by one person.

    But before that, he must first let people realize the charm of science, and to do this, he needs some strange skills.

    ……

    On the main street of Tiandou City, there is a small shop called technology commodity city. The shopkeeper neither sends leaflets nor solicits business, and there are few goods on the container.

    The only eye-catching thing is the huge glass window in the shop. Such a large piece of glass, which has never been seen in the Imperial Palace, is installed in such a shop with cold business. Passers-by can only lament a terrible thing.

    However, people are curious after all. This shop has been open here for several days, and finally ushered in its first guest. The visitors are dressed in silk robes. Although there are no embroidered marks, they can also see that they are aristocrats of aristocratic families. Only these people will step into the studio because of curiosity.

    After entering the store, he felt cool for some reason. As soon as he stepped into the store, he heard a young man''s voice: "human blood cells can be roughly divided into three types: red blood cells, white blood cells and platelets. These three cells are responsible for..."

    He understood every word of the lecture, but he didn''t know what it meant when they were connected. He was conceited that his knowledge was no worse than those of famous scholars, but he didn''t understand the knowledge spoken by the owner. He immediately became more interested in the store and coughed gently to remind the two people in the store.

    Dugu Bo was stunned when he was telling Dugu Bo about the characteristics of human blood. Then he realized that a guest came and said to Dugu Bo, "let''s stop here today. You can sort out what you have learned in recent days." After that, he turned to face the guests. Seeing that the visitor was well-dressed and didn''t have any family, Hui couldn''t help but pick his eyebrow.

    "What do you call me, sir?"

    "Just call me night!" The young scholar''s elegant smile makes Chengying thoughtful. He claims to be the noble of Tiandou city at night. At this age, will he be the snow night emperor in the future?

    The film was just a guess, but he didn''t say anything. Whether it was the future emperor or not had little impact on him.

    "What? Don''t you tell me what you sell in this shop? "

    "As you can see, the shelves are full of goods." The photographer pointed to the glass counter.

    The night smelled the speech and smiled: "you should say that the glass shelf is more valuable!"

    "If you have to buy a pearl, you can''t sell it at this counter." The film also smiles.

    Night thinks that Chengying is a very interesting person and his words are also very interesting. Although he has never heard of this idiom, he can easily understand its meaning.

    "That''s to ask the shopkeeper to introduce your pearls."

    With that, he picked up a small bright silver iron box and opened the lid. He thought there were some rare gemstones in the box, but he didn''t want a flame to suddenly pop out of the box and startle him.

    "As you can see, the lighter is still a useless toy for the time being, but it will become useful when the tobacco smoked by those tribes in the South comes."

    Night also understood the meaning of the film. Such an exquisite lighter must be valuable. The poor can''t afford it, and the nobles have servants who can''t use it. The only function is to force them when they go out hunting.

    Put the lighter back, he picked up a small carton and shook it. There seemed to be several sticks in it: "what''s this?"

    "It''s similar to the one before. It''s also used for ignition. This is called a match." With that, Chengying took the matchbox and lit it. The bright light of the fire made the night nod. If this thing is cheap enough, it''s a good thing.

    But the film soon dispelled his idea: "this thing is still produced by hand. The cost is too high. People don''t have a habit of lighting fire often. At best, it''s just a plaything, but there''s something about this white phosphorus match that can''t be compared with anything else."

    Then he took out a match, broke off the match head and said, "white phosphorus, a brand-new highly toxic, these in my hand are almost the lethal dose."

    The night couldn''t help taking a step back, and her eyes looking at matches were no longer looking at playthings.

    "Don''t worry so much. If you eat it carelessly and wash your stomach to induce vomiting, you may still survive." Although Chengying said so, the night still looked dignified.

    It''s not that he hasn''t seen it before, but it''s also a deadly poison. People can''t be afraid of it.

    "Forget it. If you don''t like matches, just look at this." Then Chengying took out something like a glass kettle and handed it to Chengying. Under the glass kettle was a metal jar with a metal gear on it.

    "What is this?"

    The undertaker took off the glass cover, took out a match and lit the wick below. Suddenly, the bright light was released from the wick. Even in the daytime, it was very clear, much brighter than the candle.

    "If the kerosene lamp is too bright, you can rotate this gear for adjustment." With that, the bearing turned two gears, and the light became like a candle.

    "It''s a little interesting. You don''t need to cut candles, and it''s brighter. If you are willing to sell in large quantities, many big families should come to you to buy it." Night seemed very interested in the kerosene lamp: "but what does it burn? It never lights up out of thin air. "

    "The kerosene lamp naturally burns kerosene. A barrel of gold soul coin is not expensive! I''ll sell it now! If you want to buy the manufacturing technology of kerosene lamps, you can also sell them to you. " The filmmaker smiled cunningly.

    "You can do business. Kerosene lamps are bought and sold with a hammer, but kerosene can flow continuously, but a barrel of gold soul money is not expensive."

    A gold soul coin is probably enough for an ordinary family of three to save money for a month, but it is really nothing for the big family. Although kerosene lamps can also make money, they can''t see it at night. He is very interested in the refining method of kerosene.
