"Alas! I can''t help it. The master and the teacher''s mother are showing their love again. They are all hundreds of thousands of years old and still look like children. " Dugu Bo, who was reading an introduction to human immunology at night, sighed and closed the window silently.

    These days, he has been used to it. On the surface, the master and his mother are the relationship between predators and prey, but in fact, it''s not the case at all. Maybe they don''t know it. The sour smell of love they emit is almost greasy.

    Curve wrecker make complaints about his own disciple''s Tucao. In his opinion, the student of the Gu Gu Bo is still very qualified. In such a few days, he has learned 7788 of the basic biology. All the elements of the periodic table have been carried away by the chemistry. It is simply a learning tyrant. It does have some potential to become a big snake pill.

    After giving the flint gun to the ice emperor and teaching her how to hit the target, she actually liked the entertainment of shooting and began to act coquettish when she hung it on the back of the film.

    "What about the kind of fire gun that can fire repeatedly and shoot more accurately? Do it quickly! "

    "Er... Well, I want to! But I can''t! As for the one in your hand, I asked the blacksmith to knock it out one by one, and then I polished and assembled it myself. It is impossible to produce in mass. As for more advanced firearms, it is very difficult.

    You can see! The reason why the firegun can launch bullets is that it uses the gas generated by gunpowder explosion and the driving force generated under high pressure. If the thread locking accuracy of the barrel is not enough, the high-temperature gas will be ejected from the gap here, blinding the shooter''s eyes and even directly exploding the chamber.

    If you want to get guns that can be loaded and fired repeatedly, you must improve the machining accuracy of parts. This is not what I can do alone. " The photographer shrugged helplessly.

    "What! Then you boast that there will be weapons that can destroy the Empire! " The ice emperor was so dissatisfied that he rubbed his chin on the shoulder of the filmmaker.

    "Sooner or later, I''ve hired people to collect all kinds of minerals. When I find uranium ore, it''s not far from the brightness of the sun." Chengying took the ice emperor to her front, reached out and scraped her nose and said, "we still have a long time. Take your time. Don''t worry. Let''s start with a more comfortable life first!

    I made some good things to remove the sour and astringent taste of fruit wine these days. Come on! I''ll show you some fruit wine without astringency! "

    The ice Emperor didn''t take it seriously. He just took it as another invention similar to hot pot, swallowed his saliva and followed.

    Chengying knows that cooking lard to make soap is an important by-product.

    Glycerol is not only an important raw material of unstable high explosives, but also a special drug for the treatment of heart disease. It can make a cup of fruit wine on a copper plate better than a cup of ale on a silver coin.

    This is also one of the treasures of the town store

    In the second half of the night, the ice emperor, who drank fruit wine as fruit juice, fainted and fell asleep on the table. After the film took the drunken ice emperor into the bedroom, he couldn''t help shaking his head and sighing.

    "It''s been four hundred thousand years. I''m still in this shape. I can''t do it at all!" Although Lori is very cute, there are not many people who really have the heart to push down.

    ……

    In the later days, there were some surprises every day. Either the film produced some new food, or Dugu Bo''s snake ate frogs.

    When Dugu Bo was taught to dissect frogs, this guy didn''t resist at all, which made the filmmaker more sure that this guy had the potential to become a big snake pill.

    With the popularity of kerosene lamps, an endless stream of guests came to Chengying to buy kerosene or wholesale kerosene, and gradually the business of small stores became prosperous.

    The ice emperor still likes to roll in the pile of gold coins, so that he had to wash all the money he received in the end, literally, with water

    Later, I didn''t know which cook had an idea. He probably took the film as Doraemon and asked him: you sell everything here. Is there anything that can make the food delicious?

    Chengying thought about it and asked him to come back in a few days. Then he used fermented soybeans and wheat to extract sodium glutamate, which is commonly used in the kitchen. Although the purity is not high, it can make a bowl of clear soup delicious as long as it is a little.

    When the cook got it, he was shocked and became a famous chef in Tiandou city in a short time. However, it didn''t last long. After the filmmaker felt that the advertising effect was almost the same, he began to sell monosodium glutamate publicly. Although the cook fell off the altar, he was embarrassed to blame the filmmaker.

    Since then, many smart people have realized that the of this small store is not simple, so they really took the film as Doraemon and went to him for any ideas.

    Some people thought the fruit wine was hard to drink, so they found Chengying and wanted the wine to be good, so Chengying sold him a small bottle of glycerin.

    Some people think that winter is too cold and cotton padded clothes are too thick. If they want lighter and thinner clothes, the filmmaker bought hundreds of ducks, drew a picture and hired a tailor to make a down jacket that can highlight their figure in winter.

    Some people thought that the two wheeled carriage had too little cargo and asked him if there was any way to change it. So the filmmaker called his carpenters and taught them to make four wheeled carriages by hand. A few days later, he pulled out a stable and heavier four wheeled carriage.

    Even one day, someone secretly asked him what to do if he didn''t want to have a child when he did that. Chengying had a black face, made a cover for him with sheep intestines, threw it to him, and told him not to find him with such questions again.

    Then the next day, a woman blushed and asked him what to do when she came to the moon. She wanted to explode in place immediately, but she made a cloth bag wrapped with plant ash and threw it to her in line with the principle of equality between men and women, and said that this shop did not operate. Whoever likes imitation, he will sell it.

    Over time, people thought that the film was very powerful and could do anything. Even some poor people came to him and asked him what to do if they wanted to burn coal in winter. It was difficult to light it, and large pieces of coal were too expensive.

    The filmmaker didn''t have to make money, so he told them to buy cinders that no one wanted, and then showed them how to mix cinders with clay to make honeycomb briquettes that can be ignited easily.

    The poor people saw the film and were willing to answer their questions, so they were no longer afraid and asked him how to make their food less difficult to swallow.

    This film is the best. The people of the once big food empire are best at having fun in bitterness. Even the bitter fern roots can be developed into delicious food. This problem is not difficult for him at all.

    After a series of things, the film''s fame has grown. It seems that he can solve any problem. Even if he can''t solve it, he will be able to give an improvement plan.
