I really don't want to be a rebel [infrastructure]

We all know that extracting cream from milk requires a centrifuge, and the centrifuge needs a motor to work well.

Luo Shixing thought about it seriously. It is estimated that the motor will not be available for a while, so he can only look for other driving forces.

And in this place where they are, there is probably nothing better and more convenient than driving in water.

He only needs to make another water wheel similar to a water wheel to provide driving force, but the water wheel is erected on the shore, and the one that powers the centrifuge is lying prone in the water, so that it can rotate better. The horizontal bar of the centrifuge allows the centrifuge to rotate quickly.

The only disadvantage of this method is that if the centrifuge wants to have enough speed, it must find a place where the water flow is turbulent enough, otherwise the speed of the centrifuge will not be able to achieve the effect of separating the fat in the milk.

However, the effect is not very good even in this way. The main function of the centrifuge is to separate the water and fat in the milk.

The problem now is separation, but not complete separation.

What came out was like cream but much thinner than cream.

Luo Shixing thought about it seriously, if the milk is not thick enough and the cream is not successful, it is actually because the fat content in the milk is not enough, so... how about adding some fat?

He is a man of action, and he almost started to make it when he thought about it. He directly added various fats to the milk and tried it. At first, it was rapeseed oil. Although he succeeded, there was a faint taste of rapeseed oil in the cream. In ecstasy, Luo Shixing resolutely ruled out this method.

Then he used a little bit of lard. Although it tasted a bit different from the cream of later generations, it felt okay, at least better than rapeseed oil.

Because he has been tossing the centrifuge for a long time, if he delays it any longer, he is afraid that he will not be able to catch up with Cheng Jingwei's birthday, so he can only make ends meet.

With cream, of course there must be cake, and the cat-head oven that Cheng Jingwei made for him back then came in handy again.

Ever since Luo Shixing didn't cook much, the cat's head oven hadn't been used again.

Luo Shixing didn't have time to make it, and other people didn't dare to use it. After all, the servants in the family knew that it was made by the big lord for the young lord.

But even if no one used this oven, someone would always clean it every day, so Luo Shixing directly started to try to bake cakes.

In fact, it is not difficult to bake cakes. If you don’t have butter, you can use lard, and if you don’t have low-gluten flour, you can use wheat starch to dilute it. Although it is best to use corn starch, this thing should still be in the American continent, so he can only think about it. .

The egg whites of the eggs were beaten for him. Although he wanted to do it himself, he changed his mind just in time before his arm was about to break.

Now he is secretly doing this behind Cheng Jingwei's back, just to give him a surprise that day, and he has to deal with various documents every day, and Cheng Jingwei will find out if he feels a little uncomfortable.

In fact, none of these were the most difficult. The most difficult thing was that they didn't have any sugar now, and half of the recipes that Luo Shixing knew in his head were directly discarded. Anyway, the part about sugar had to be tried again.

His current substitute is either honey or maltose.

Among them, maltose is more expensive than honey. Who makes the climate here not suitable for growing wheat?The temperature required for wheat planting should not exceed [-] degrees, and there must be sufficient light.

These two items directly cut off the possibility of wheat sowing in Lingnan. Although the temperature in Lingnan is relatively low during the dry season, it is relatively unstable. The temperature may be low today and high tomorrow, and there is no way to guarantee the light.

Luo Shixing could only use honey to replace white sugar. The sweetness of honey and white sugar is different, so the ratio naturally needs to be tried a little bit.

For this reason, he baked many cakes that couldn't even enter his mouth. If it was normal, he might give these cakes to his servants to eat.

He thinks it's inappropriate because it's for Cheng Jingwei's birthday, and it can't be perfunctory, but it's still a good thing for many people.

It's a pity that he doesn't want to be eaten by others before Cheng Jingwei eats the cake, and these people may leak the news after eating.

After thinking about it for a long time, he finally threw away all the unsuccessful cakes.

Hey, he still felt very guilty when he threw it away. They haven't had such a good time yet, so they just waste it like this.

But think about it, birthdays only come once a year, and this time is because he made Cheng Jingwei sad before, and he used it to apologize, so of course he has to be a little sincere.

With his dedicated efforts, he finally mastered the ratio of honey cake. Not to mention, the cake baked with honey has a natural floral fragrance, which is also sweet and not sticky.

After finally finding a suitable recipe, Luo Shixing began to try to whip the whipped cream and shape the cake.

This is not a problem for him, he is not good at other places, but he is still good in this respect, especially he has a turntable made in advance and professional smearing tools.

In addition to spreading cream, Luo Shixing also planned to make a shape for the cake. In fact, the best choice was to pinch a sugar figurine on top, but the problem was that there was no sugar, so he had to make a biscuit in the shape of a little tiger.

Because of the limited space, he directly made the tiger's appearance look like a baby. After coloring it, it was too cute, and then Luo Shixing ruthlessly destroyed it.

You're done, just waiting for the day to come.

But before that, he had to ask Cheng Jingwei.

These days, because of the expansion of the army, Cheng Jingwei often goes to the barracks to rectify military affairs.

Although Cheng Jingwei always said that Luo Shixing was very good at thinking of those methods of training soldiers, Luo Shixing felt that those who could actually implement them were great, and he didn't invent this thing. It was easy to write casually, but it was too difficult to do.

If it hadn't been raining or cloudy during the recent period, he suspected that Cheng Jingwei might have to be dark for a few degrees.

When it finally happened to be a holiday, Cheng Jingwei didn't want to come out in his room.

He is not so lazy on weekdays, he is really exhausted recently.

Luo Shixing ran to his door and knocked lightly, lying on the bed and said lazily, "Come in."

Luo Shixing pushed open the door and poked a small head in. Looking around, he found that Cheng Jingwei was still lying on the bed. He couldn't help being a little surprised: "You haven't woken up yet?"

Cheng Jingwei turned his head and glanced at him: "I don't remember."

Only then did Luo Shixing notice that he was wearing a nightgown.

This is what Luo Shixing wanted. Before, he really wanted to go to the countryside and sleep in his underwear like everyone else, but he couldn't bear to put on a coat directly on the outside without getting up the next morning after sleeping all night.

Especially in summer, when the weather is hot and you sleep all night, you will definitely sweat. When you wake up in the morning, your underwear will be damp and uncomfortable to wear next to your body. Robe, simple and comfortable.

Cheng Jingwei was not used to it at first, but now he feels good after getting used to it.

At this time, he was wearing a white nightgown, probably because he had slept all night, the neckline was a little open, directly exposing half of his chest, and he could see the contours of his Adam's apple, collarbone and pectoral muscles at a glance.

Luo Shixing took a look and then turned his eyes away, and after silently saying "see no evil" twice, he noticed something was wrong.

It's not like Cheng Jingwei has something, so what can't he see?

When the two of them sleep on the same bed, they are quite a lot, that is to say, they are older.

Luo Shixing walked in while thinking about it and persuaded him: "If you are too tired, take a rest, you are still young, what should you do if your body is broken?"

Hearing his old-fashioned tone, Cheng Jingwei couldn't laugh or cry, raised his arms and put his hands behind his head and asked, "You don't sleep much today, Xiu Mu, what are you doing here so early?"

Luo Shixing sat down on his bed unceremoniously, and Cheng Jingwei felt a little helpless when he saw it. This was the little lynx. If it was another person, he would have kicked him down long ago.

Luo Shixing sat cross-legged on the bed and asked, "Your birthday is five days away, how do you want to spend it?"

Cheng Jing was taken aback for a moment, he was so busy recently that he forgot about his birthday, but little lynx still remembered it.

But yes, every year, the little lynx brought up his birthday celebration, and if he was asked to come by himself, he would definitely not remember it.

Birthdays are only worth celebrating when important people get together.

Cheng Jingwei looked at Luo Shixing looking at him expectantly, then smiled and said: "Let's just close the door and live casually, don't mobilize the crowd."

He knew that there should be a banquet, but this kind of banquet is usually an occasion for everyone to connect with each other. It is said to be his birthday, but it is just a formality.

In the last life, when he established himself as the king, his birthday was remembered by many people, and it was held every year with unprecedented grandeur, but he always felt empty in his heart, and he was so tense.

Now he doesn't want to be so lively, it's good to eat, drink, talk and laugh with the little lynx.

And as far as he knew, for his birthday, the little lynx, who hadn't been in the kitchen for a long time, did it himself again.

Thinking of this, his smile deepened a lot, and he restrained himself from asking what the little lynx was doing.

Although the little lynx is keeping it secret, what can he hide from Cheng Jingwei at home?After all, for so many years, the servants in the family knew that the two of them had equal status in the family, and there were no secrets between them.

Luo Shixing didn't feel anything at first and agreed casually, "Okay, you can do whatever you want."

Even though that is the case, Cheng Jingwei's birthday is not unnoticed.

Except for Luo Shixing, Xiao Shanshi's siblings and Wei Ziyao's family must all remember it. It happened to be a holiday that day, so they simply came over together to give Cheng Jingwei a gift.

None of them were expensive things. Xiao Shanshi gave him a pair of shoes made by himself, and Wei Ziyao, together with his brothers and sisters at home, gave him a root carving.

In addition to them, the bosses also came to the door. The big shots were not too expensive, and they all gave them whatever they wanted. They made up a set of the four treasures of the study, brush, ink, paper and inkstone, and someone gave him a copybook and a painting.

All in all, they are very elegant things, at first glance, they are the kind for my own juniors.

These things were probably the least expensive gifts Cheng Jingwei had received in his two lifetimes, but they made him very comfortable.

Compared with the preciousness, he values ​​the intention inside.

Luo Shixing followed him and sighed, "Hey, it seems that your wish to celebrate your birthday will not come true."

Cheng Jingwei couldn't hold back a smile, indeed, with so many people, it was enough to hold a banquet.

However, the atmosphere of this banquet was not bad. Although everyone often chatted about business matters, the atmosphere was very relaxed. It was interesting to hear the former prime ministers complaining about how stupid their subordinates were sometimes.

Everyone chatted for a while, Li Youdao suddenly realized: "Where is the lynx cat? Why don't you see him?"

Only then did everyone realize that the little lynx seemed to have disappeared for a long time.

At this time, Luo Shixing had just placed the prepared little tiger on the top layer of the double-layered cake, and baked two biscuits with numbers, which together became the word 15.

After carefully inserting the digital biscuit into the cake, Luo Shixing clapped his hands: "It's done!"

Then it's time for him to make his debut with a beautiful birthday cake!
