Zhang Youxuan breathed a sigh of relief and said, "Thank God, it would be nice if it was like this." ”

At this moment, Zi Huai came over with Du Jiu and Li Yu.

In addition to the two, there are six others, and before, Lin Yi was optimistic about the candidate.

As soon as Du Jiu came in, he said happily: "Yiyi, I heard Zihuai say that oil refining has been successful, right?" ”

Lin Yi nodded, she glanced at Zhang Youxuan, Zhang Youxuan understood, turned around and walked to the back shelf, and brought over the more than a dozen substances extracted before.

Lin Yi pointed to the tray in Zhang Youxuan's hand and said, "Everyone, these things are what we extract from oil, this one, called gasoline, is the most precious thing in oil, and this will be used in the engine of the machine." ”

Du Jiu and Li Yu, according to Lin Yi's previous description, have been studying the manufacture of engines in the past few days, because Lin Yi's gasoline has not yet been refined, so they are now using ordinary lamp oil.

However, the results were not ideal.

Li Yu felt a little sorry for Lin Yi, and said very ashamedly: "Owner, I'm really sorry, you drew drawings for me before, but I still can't make this engine, I'm really useless." ”

"Hey, stinky boy, you said you were useless, didn't you even bring me with you, this engine, I don't think it's so simple." Du Jiu was on the side and said with some dissatisfaction.

In fact, he was also a little annoyed in his heart, obviously Lin Yi told them what the principle of the engine was, and also drew a picture for them, but in the past few days, they have spent a lot of effort to make three strange-looking machines, but these machines look very similar to what Lin Yi painted for them, but they have no effect that Lin Yi told them.

Both of them are skilled craftsmen, and they both have ingenious craftsmanship in manufacturing technology, but modern science, after all, is an academic discipline that has been accumulated for a long time, and although they are very talented, they cannot achieve it overnight.

Lin Yi smiled slightly, and said with relief: "Uncle Du Jiu, Li Yu, manufacturing engines is a difficult technology in the first place, otherwise I wouldn't have handed over this problem to you."

Before, the picture I gave you was just a simple drawing, and there were many things in it, but I had never drawn it, so it was normal for you to not be able to do it in a short period of time. ”

Li Yu frowned slightly and said, "Owner, we haven't done it yet, will it delay the work in the future?" ”

Lin Yidao: "Originally, I explained the principle to you before, just to think that you should study this first, and when you have experience, it will be easier to understand later."

Moreover, I originally wanted to wait for the gasoline to be refined, and then use the gasoline as fuel, and work with you to focus on overcoming the technical problems behind, so you don't have to worry, this machine will come out a little later, it doesn't matter. ”

In Lin Yi's heart, he naturally hopes that the engine can be developed as soon as possible, but this is unrealistic, in this era, it is so backward, and the accumulation of science and technology is pitiful, even if you take a whip to drive people behind, it will not be able to drive out.

Instead of everyone's stressful work, it is better to let everyone take it easy, so that maybe the progress of research and development can be faster.

Although Lin Yi said that it was okay to be late, Li Yu made up his mind in his heart that he must build the engine as soon as possible, and he must not hold back the owner.
