In mid-September, the weather gets cooler.

As the place where Li Yuanjia stays the longest on weekdays, the stuffiness of the study is long gone, so Chunyan and her daily life also save the hard work of moving ice cubes into the study. In Li Yuanjia's small kitchen, Yu Niang and the others also saved the trouble of making ice with saltpeter every day and then recycling saltpeter back.

You know, whether it is ice making or recycling saltpeter, it is very troublesome, and it is the most tormenting.

But this is still good, if it was really annoying two years ago when the king had just ordered them to figure out how to make ice from saltpeter......

Seeing that it was noon, Chunyan and the others came over to invite Li Yuanjia to lunch.

"No, bring the things to the study."

Li Yuanjia was busy finishing up the latest math book, and the last few hundred words were left to finish his work, where did he have the heart to eat, he ordered without raising his head: "In addition, my willow charcoal pen is running out, let people hurry up and make some more for me!" ”

"Yes, King!"

After hesitating for a moment, Chunyan finally gave a salute and went out.

It was not good to eat in the study, but they were used to it when the king often commanded them. As for the willow branch charcoal pen, it looked a little awkward at first, but since the king likes to use it, they naturally mastered the method of making it, and it was a matter of hand.

In this little girl's heart, as long as the king is not as scary as before, everything is fine.

In the first two months, the king was always sad, and he didn't eat very seriously for a long time, and finally he was so thin that people were shocked. Fortunately, I have finally recovered a little in these days, so that everyone can be relieved.

Not only Chunyan and Liu Mei, but in fact, all the subordinates in the palace were worried to death.

Because on the one hand, Li Yuanjia is very generous to them on weekdays, and everyone naturally compares their hearts to their hearts; Second, for the people of the palace, if the king has three long and two short, even if they are not held accountable, I am afraid it will be difficult to meet such a good master......

Yu Niang and the others had already prepared, and the kung fu meal was brought to the study after a while.

Originally, I wanted to insist on eating it after I finished writing, but when the aroma of hot dishes and soup rushed to my nose, Li Yuanjia couldn't help it, threw the charcoal in his hand aside, stood up and walked to the small table specially used for eating.

The dish is very simple, just two dishes and one soup.

A dish of fried tofu, a dish of fried vegetables, and an egg drop soup, and four big steamed buns - Li Yuanjia is only eighteen years old now, and he has to run and exercise every day, and the amount of food is not ordinary. At this time, I felt hungry, so I grabbed a steamed bun and gnawed it down.

looked at the sweetness of the king's food, but the willow eyebrows who were waiting next to him were sad for a while.

If you count it, the king doesn't know the taste of meat for four months.

The king, who is almost happy with meat at every meal, now because of filial piety, not to mention his favorite braised pork and braised mutton or something, now he refuses to even eat a shredded meat! It's green vegetables and tofu every day, and at most it's an egg or something, which makes people feel distressed to watch......

Chunyan and Liu Mei felt sorry for Li Yuanjia, but he himself was eating while pondering the math book he was writing just now.

Taking advantage of the opportunity of "pure heart and few desires" in the past few months, Li Yuanjia really worked hard and wrote all the junior high school mathematics that he could still remember in one go. It's just a pity that although he was also a good student with more than 600 points in the college entrance examination that year, after so many years, even the mathematics knowledge of junior high school, Li Yuanjia only wrote half of it at most.

Maybe he can remember more when others say it, but it's really useless to think so on his own!

So, the unforgettable gold finger has a hairy use?

Once again, he secretly complained about his reborn golden finger, Li Yuanjia stuffed a piece of tofu into his mouth, and secretly thought: "If there is no accident in the future, mathematics should end here, and what it can develop next can only depend on other people...... Hey? This tofu tastes good, who makes it? ”

"Back to the king, it's my new one."

After listening to Li Yuanjia's praise, Liu Mei suddenly felt happy in her heart, pursed her lips and said in a low voice: "I have nothing to do, so I tried to do it according to what you said, but I didn't expect it to look good after I came out...... If you like it, I'll make it for you every day. ”

“……”

Looking at Liu Mei's well-behaved appearance with low eyebrows, Chunyan, who was standing opposite, couldn't help but pout.

Tried to do it?

It's very easy to say, but whoever has tried the king's method to make tofu, who doesn't know the hard work? can make tofu better than Yu Niang's cooking, this girl got up in the middle of the night to grind beans, she thought she didn't know?

Li Yuanjia naturally didn't know the twists and turns in the hearts of the two girls, he just listened to Liu Mei's words, nodded again and again and smiled: "Not bad, it's better than what Yu Niang made...... But you don't have to do it every day, you can do it once every ten years. ”

Sandwiched another piece of tofu and stuffed it into his mouth, Li Yuanjia was really satisfied.

In the past, he always thought that tofu was invented in the Han Dynasty, and many people said that it was obtained by accident by Liu An, the king of Huainan. But after coming to the Tang Dynasty, at least Li Yuanjia had never seen such a thing as tofu. Fortunately, he had forgotten at least half of the important basic knowledge of junior high school mathematics in his previous life, but he had seen such a thing as making tofu once in a farmhouse, and he still remembered it clearly.

A few days ago, I remembered to talk to Yu Niang, but I didn't expect them to do so well so quickly!

And......

"In addition to being delicious, this thing is very useful!"

Taking a bite of the big steamed bun, Li Yuanjia pondered about developing more dishes made of tofu as soon as possible, preferably without any oil, such as tofu skin, tofu or whatever, so that this thing could be popularized among the people as soon as possible.

The Chinese people lack meat to eat, and this situation may continue for thousands of years in the future.

Tofu, which is also suitable for Chinese appetite and can supplement protein, is definitely the best food to continuously improve the height and physique of Chinese. In a sense, it's also one of the best alternatives to meat – and while it's sad to say, the reality is that productivity in this era is not available to everyone...... Or rather, the vast majority of people supply meat, providing the protein they need.

Tofu is definitely indispensable in the history of China.

It's a pity that Li Yuanjia just pondered about other ways to make tofu for a while, and Han Shan hurriedly knocked on the door of the study, and then said nervously after coming in: "King, Chang'an has a will!" ”
