Text Chapter 98 The Fig Tree

Previous page        Return to Catalog        Next page

    Speaking of rubber substitutes, Li Min immediately thought of one thing. When he made his first bicycle in Chang'an, the craftsmen in Fuzhong used a special rubber to coat the wheels. It seemed to be very wear-resistant. Maybe  Maybe it¡¯s possible?

    Thinking of this, Li Min hurriedly called the two stewards Huang Cheng and Lao Wutou over. These two people turned out to be the head craftsmen of the wood and iron workshops in his mansion, because they helped Li Min make a lot of new things.  Things, so he was promoted to steward, and the bicycle was successfully developed under the leadership of the two of them.

    Yifan didn¡¯t know what Li Min asked the two stewards to do, so he looked at Li Min strangely.  After a while, the dull Huang Cheng and the strong old Wu Tou rushed over. When they saw Li Min, they immediately saluted and said, "I see you, my lord!"

    "Get up. When I asked you to make that bicycle, you put a thick layer of glue on the wheels. That glue seems to be very tough. Is it still available in the house now?" Li Min asked the two of them to get up, impatiently.  Asked.

    When Li Min asked about this, both of them were stunned. This time, the more talkative old Wu Tou did not speak, but looked at the very dull Huang Cheng, because Huang Cheng made the glue.

    "Your Majesty, that kind of glue was originally discovered by a villain. However, this kind of glue is not very sticky and has limited use on wood. I don't usually have it on hand. I will make some freshly only when needed. But now I want to do that.  Planting glue is not that easy anymore." Huang Cheng hesitated for a moment before answering honestly.

    "Oh? Why is this?" Li Min was very surprised when he heard this.

    "Your Highness, that kind of glue was boiled by the villain from the sap of a kind of fruit tree, but that fruit tree was just introduced to our Tang Dynasty not long ago. It is only grown around Chang'an. This time I came to Dengzhou. Although the villain also brought it with me  There are some seeds, but they have only been planted for a year and there is no way to get the sap." Huang Cheng said helplessly.

    Tree sap sounds so much like a rubber tree, but Huang Cheng clearly said it was a fruit tree, but in Li Min's memory.  Rubber trees don¡¯t seem to produce any fruit?

    "What's the name of that fruit tree, and does it have any characteristics?" Li Min asked hurriedly. Rubber trees are still far away in the American continent, and it is impossible for them to spread to the Tang Dynasty.  Therefore, Li Min quickly dismissed the speculation about rubber trees.

    "Your Majesty, I heard that this kind of fruit tree was brought by Hu merchants from the West. I didn't know its original name. But after it spread to my country in the Tang Dynasty, because the fruit it bears is as sweet as honey, it was called  Honey fruit, and this kind of fruit is very strange. It bears fruit without blooming, so some people call it fig!" Huang Cheng bowed and answered again.

    "It turns out to be a fig!" Jing Huang Cheng said.  Li Min immediately remembered that he had eaten a lot of figs when he was in Chang'an, but he didn't pay attention to it at the time. After all, figs were very common in later generations, so there was nothing surprising about them. But he didn't expect that this thing would be so delicious.  It was just introduced in the Tang Dynasty.

    "Your Highness, we are in the palace of Chang'an. We have planted a lot of fig trees. Your Highness must have tasted figs. If necessary, I am afraid they will have to be transported from Chang'an. But this time, it will take almost two months.  It's over!" Huang Cheng replied honestly.

    In fact, Huang Cheng didn't know that since Li Min presented the bicycle to Li Shimin, Huang Cheng's method of making rubber was also presented to him, and he would imitate the bicycle. With the promotion of bicycles, there was a demand for rubber on the wheels.  Naturally, the number of fig trees has increased significantly. Although many people in Chang'an City have begun to plant fig trees in large quantities, the time is too short and the sap cannot be obtained at all.  In this way, mature fig trees are even more precious. The ones planted in Li Min's house have been purchased by General Supervisor at a high price, and the trees have also been removed. However, this matter is too small. Li Min, who is far away in Dengzhou,  Min and Huang Cheng didn't know at all.

    "Okay, then you set off immediately and rush to Chang'an to make that kind of gum as soon as possible. The more, the better. If it's not enough, let Mr. Wang help you find a way!" Li Min immediately ordered.  Mr. Wang is also Wang Zihao. Xijun has entered his house, and Wang Zihao has become his elder. It would be disrespectful to call him by his first name, so he changed his name to Mr. Wang, and everyone in the house knows about it.

    "I obey!" Huang Cheng also knew that His Highness was going back to Chang'an, but now he asked himself to go first. Obviously this matter was very important, so he did not dare to neglect it. After saying this, he immediately went back to his house to prepare, without even eating lunch.  Da Ma left Dengzhou.

    "Rokuro, didn't you say you were looking for rubber? Why are you looking for figs?" Yifan asked with a puzzled face. In fact, she wanted to ask just now, but she couldn't get the word out.

    "Rubber is good, but we can't find it in Datang, so we can only settle for the next best thing. We tried the glue made from figs, but it should be about the same." Li Min looked very worried when he said this.  No confidence.  In fact, he did not know that figs and oaksAll trees belong to the same family, and the sap they produce can also be used to make rubber. Of course, the yield is not as large as that of rubber trees.  As for the glue made by Huang Cheng, the ingredients inside are almost the same as rubber.

    Putting aside the issue of steam engine sealing for the time being, Li Min then carefully observed the operation of the steam engine, and discussed with Yifan the shortcomings and areas for improvement.  In fact, the reason why the horsepower of this steam engine is so small is that in addition to the air leakage, there are also quite a few problems with the design. This is not a problem with Yifan's ability, but when it was originally designed, it was just to make it work.  With continuous operation, as long as this basic requirement is met, the horsepower can be improved step by step on this basis.

    In this regard, after Yifan made the prototype of this steam engine, he has already begun to design a new steam engine with the purpose of improving the power of the steam engine. With this prototype as the basis, I believe that the design of the new steam engine will be completed soon.  , but due to process and sealing issues, even if the power is increased, it is estimated to be very limited.

    The craftsmanship cannot be improved in a short while, and Li Min, an outsider, cannot help at all. The only problem that can be solved is air leakage. As long as sealing materials can be found, I believe it can be solved.  Although it would still be a huge waste to greatly increase the power of the steam engine, it would definitely be practical.  At least it won't be like the prototype in front of them, which can only be used as a decoration.

    Thinking of this, Li Min became more determined to solve the air leakage problem. If the glue made by Huang Cheng still didn't work, then he would publish the map from the American continent to Asia, and then offer a huge reward. I believe he will get a big reward.  There must be brave men, there must be people who dare to take huge risks and give it a try, even though the hope of success is very slim.

    After watching the steam engine, Li Min spent another half day in the Academy of Sciences. He went to other groups to check their progress and helped out if he could think of it. Of course, Li Min's level was definitely that of a fool. He could  It doesn't really help much.  At noon, he returned home to have dinner with Wen Xin and the others, but had to go out in the afternoon because Wu Meiniang wanted to see him.

    Wu Meiniang still lives in the house that Li Min arranged for her. Although Li Min has long loosened control over her freedom, in order to avoid unnecessary trouble, Wu Meiniang has always lived in seclusion. Unless necessary, she rarely goes out.  When I go out, I will also dress up, and I will also call Yang Shi and his wife.

    After not seeing each other for several months, Wu Meiniang naturally missed Li Min very much. For this reason, she specially cooked some authentic Guanzhong side dishes, warmed up a pot of light wine, and sat at the table very obediently, waiting for Li Min.

    Li Min opened the door and saw the scene in front of him, especially Wu Meiniang, who was wearing regular clothes and sitting lazily on a chair. When she saw him coming in, she smiled slightly, opened her red lips and said, "Husband, you are back.  ?¡±

    In just a few months, Wu Mei Niang was more charming and touching, especially because of the heat, and she was thinner, and she also showed her bumpy figure, making people unable to see her eyes at first sight.  In total, Wu Meiniang is one year younger than Wen Xin, but her physical advantage is not the slightest bit better than hers. However, this is something she is born with and cannot be learned no matter how hard she works.

    Li Min looked at her well-behaved appearance, just like a distressed little wife, and at that moment some tenderness surged in his heart.  In fact, Li Min didn't think much about Wu Meiniang at first, but after getting along with her for this period of time, he suddenly discovered that the other party had actually broken into his heart a long time ago. Especially in the past few months of separation, he had nothing but Wu Meiniang.  I miss Wen Xin and Xi Junwai, and what I miss most is Wu Meiniang in front of me.

    "Meiniang, thank you for your hard work during this time!" Li Min walked forward quickly, picked up Wu Meiniang from the chair, put her on his lap, and then said softly.  During this period, he was far away in Goguryeo, and all intelligence matters were taken over by Wu Meiniang. This made her burden suddenly heavier, so Li Minhui said this.

    "Hehe, no matter how hard Mei Niang works, it can't compare to the hard work of my husband on the battlefield, killing enemies for the country!" Wu Mei Niang said with a naughty smile.  She knew clearly that Li Min was just a foil on the battlefield, but she still said this, obviously joking with Li Min.

    "Of course, my husband is very brave on the battlefield. The two general managers Li Ji and Niu Jinda must be very good at using troops, but they were blocked by a small Anshi City. In the end, I was not my husband and I rushed there.  Anshi City was captured in one fell swoop, and even the city lord was killed, as well as the King of Goguryeo"

    Li Min naturally heard that Mei Niang was joking on him, but his face was already thick to a certain extent. He immediately followed her words and began to brag about his heroic appearance on the battlefield, using bragging to put himself on the battlefield.  I recounted my experience.  !  ~!
