Li Shimin's secret decree soon reached Yuan Tiangang's hands.

Also arriving at the same time were a seven-foot middle-aged strong man and a young woman with bright eyes and bright teeth. This is the waiter sent by Li Shimin and the eldest grandson clan to serve Shu Hui, the "Xuan Turtle Transformation Prodigy", and may also shoulder the purpose of monitoring Shu Hui's movements at any time.

The strong man has a white face and no beard, wears a round neck, narrow sleeves, and a straight brocade robe, and carries a ring-headed horizontal knife around his waist. The dragon walks and walks majesticly, and is the personal guard given by Li Shimin to the prodigy.

The woman's cloud hair was reversed into a draped bun, and she was wearing a deep coat with drooping sleeves and sleeves. smiled before speaking, with affection in her eyebrows, she was the eldest girl sent by the eldest grandson to serve the prodigy's daily life.

"But how do you wear this to serve my daily life?" Shu Hui looked helplessly at the woman named Hongyu, who claimed to be his maidservant. This cumbersome dress doesn't look like it's used to take care of people.

The red fish smiled and replied in a unique sweet voice: "The mother sent a slave maid to serve the god on her behalf, of course she has to wear a sacrificial dress." As he spoke, he made an aggrieved expression: "Don't you like the dress of the slave maid?" ”

Shu Hui knew that as a "god", his image was too gentle compared to those legendary Ru Mao and blood-drinking kinds. So much so that like Hongyu, who is quite favored by the queen's side and has seen many big people, the palace people are not very afraid of him.

"Remember, call me young master from now on." In the past few days, in the dead of night, Shu Hui will also think back to his past life. Do you have friends who will be concerned about your departure, and how sad your parents and brothers and sisters will be.

Then he was surprised to find that he was not as difficult to face as he thought. It's not that he has become cold-blooded unconsciously, it's that he doesn't remember his family very well.

After looking through the system log, Shu Hui learned that he had lost a part of his memory before traveling through time and space, so when the system reproduced him, it eliminated the personality that reacted most strongly to this part of the defect.

This was obviously so cruel logically, but he couldn't even feel sorry for it for the time being. Of course, his personality will be gradually completed in Shu Hui's growth, and he will almost adapt to this change by then.

But no matter what, Shu Hui has the impression that his parents are still alive and well, and they seem to be still in the prime of life. There are a pair of children under his knees in addition to himself, and he is not worthy of the title of master.

"Yes, young master!" Named Ao Guang, the taciturn man hugged his fists, quite a military style, and the maid Hongyu also obediently agreed. Although Shu Hui's body is only a three-year-old child, many water gods have the image of this child. Regarding Shu Hui's "legal decree", the two obeyed their orders.

At this time, a government official from the county office came to report, saying that there were people outside who wanted to see the red lady.

Hongyu's eyes turned, and he saluted Shu Hui: "When I came before, the slave maid had already set up a house outside the back door of the county office, and now Xu is already settled. Do you want to take a look together? ”

Shu Hui wasn't interested in this, he cared about another thing. Shu Hui remembered that there was a small garden behind the inner hall and the third hall of the county office, and he often went there in recent days to relax, and he also tested the effect of air purification there - he didn't remember any back door there.

"Does this county office have a back door?" Now it is not like the Ming Dynasty, the back door of the county office repaired the city god temple. In the Tang Dynasty, the county office was generally a wealthy area, and if there was a back door, wouldn't it be convenient to give and receive privately?

Redfish replied rather slyly, "Not now, but when the house is chosen, it will be there."

Li Shimin secretly ordered Yuan Tiangang to take care of Shu Hui's needs in Huojing County. But Yuan Tiangang is only a county order after all, although he can take care of it from the official side, but I am afraid that he will inevitably be slack in the reception specifications of the prodigy. So he and the queen eldest Sun each sent one person to take care of Shu Hui's daily life, first set up a house near the county office, so that Yuan Tiangang could take care of it, and ordered Yuan Tiangang to recruit forced labor to repair the Xuangui Temple in the north of the fire well during the agricultural break.

Shu Hui didn't know about this, he just told Ao Guang to follow Hongyu to take care of one or two. He had only been in this era for a few days, and he hadn't figured out what the security situation in the city was, so he had better be careful.

"Yes, young master, our family is leaving." This is the county office of the county office, so you don't have to worry about safety, but you don't have to leave an inch.

Well? Our family?! Shu Hui was taken aback, this man who is more than a master is not a pure master, but a eunuch? It's really unexpected.

In fact, this is what he thought, our family's self-proclaimed title is not exclusive to eunuchs, but the humble title of people outside the party. At this time, eunuchs did not often use this word.

After the two of them left for a while, Yuan Tiangang walked in with Gong Cao Muquan. Na Gong Cao was holding a food box in his hand, and when he opened it, he saw that it seemed to be a white tofu brain, which made Shu Hui's eyes light up.

"This is soybeans that were sown in early spring, and now they will be pods, probably the first bowl of tofu this year." After many days of getting along, he has learned that Shu Hui seems to lack interest in meat. It seems that even if the turtle transforms, it is a child after all, and he can't eat too much greasy. So he always changed his tricks to make some fresh dishes, and brought them to Shu Hui with complex emotions that were both like worshiping the gods and seemingly teasing his grandson.

"Chilled, eat it while it's cold, it's the most refreshing." Yuan Tiangang smiled and took out three porcelain bowls from the food box, and he and Mu Quan took the lead in demonstrating the two bowls.

Shu Hui looked at the one in front of him with suspicion, it did look like tofu brain, and its name was also tofu, but is there still such a thing as eating it while it's cold?

While others sit and eat, he can only stand. People have short calves, which is very inconvenient. I picked up the spoon and scooped it up, and it smelled like soy sauce, with a little sweetness. There is a vague meaning of tofu, but the most impactful taste of Shu Hui is the sultry smell, which even makes it difficult for him to swallow.

"Is this really tofu?" Shu Hui thinks that if this is really tofu, it is the most unpalatable tofu in the world.

It's just a snack, and you don't have to follow the rules of eating and not saying a word. When Yuan Tiangang heard this, he said that this is a special food that has been circulated in the local area for many years.

The locally grown spring soybeans are fully ripe in June and July, when the weather is at its hottest. In addition, the local abundance of well salt, the tofu ordered by the brine filtered by boiling salt is fragrant and smooth, which is the most refreshing but the tofu ordered in other places is not so delicious.

A bowl of iced tofu, sprinkled with chopped soybeans and drizzled with soybean paste, the taste is simply wonderful.

Mu Quan also sighed: "Yes, this bean sauce is sweet tofu, but it is the favorite of Wu Shaofu (the honorific title of the county)." It's a pity, I don't know if he will be able to eat it in the future. ”

Talking about this colleague, Mu Quan was quite depressed. It's not that their relationship is deep, but that Muquan has a younger sister who is married to a big family in a neighboring county, and last year she also had the same disease as Wu Xiancheng. She didn't make it through and left not long ago.

Shu Hui heard them talk about the county, so he inquired a few words. He didn't know much about the official configuration of the county office, and he didn't know that there was such an official position before, and he hadn't seen this person for a few days. Now listening to Yuan Tiangang's explanation, I know that the county Cheng has a stone shower, and his condition has deteriorated not long ago, and he has been recuperating at home for more than ten years.

"This stone shower is a common disease in this county. Almost 1 in 20 people suffer from the disease. The imperial court once sent a medical officer from the Imperial Physician's Office to check the cause, but did not get an answer, only saying that it might be affected by the water source. ”

Hearing Yuan Tiangang say this, Shu Hui quickly threw away the spoon in his hand.

Why does this stone shower sound so much like kidney stones? After further investigation, sure enough, Shi Lin was the kidney stone in Shu Hui's memory. There are so many people suffering from kidney stones in one area, causing the population to wither, and it is no wonder that the imperial court will send imperial doctors to investigate.

However, if it is said that it is the influence of water sources, it is not easy to explain, after all, a county is not small, and the water sources are also diverse. In some places, water may be taken directly from the river, but the same river basin does not have such a high risk of disease.

"You tofu ......" Shu Hui pointed to the porcelain bowl in front of him and asked in disbelief, "It can't be raw, right?" ”

"Raw?" Yuan Tiangang asked strangely, looking inexplicable at this question. Then he said with some smugness, this is the brine filtered by refining salt from the fresh bean juice, and the inventor is none other than Liu An, the immortal who soared in the day in their Taoist mythology. Legend has it that this tofu was a delicacy that he happened to make when he was experimenting with refining the elixir. Therefore, people believe that eating tofu can prolong life.

Especially in Huojing County, where soybeans are grown locally and there is brine, it is normal for people to eat tofu.

But—

"In other words, this tofu is made by grinding soybeans into juice and then adding brine directly?"

Yuan Tiangang didn't understand why Shu Hui cared so much about this issue, but the prodigy couldn't be lazy, he replied that it was not directly added to the brine, but also filtered with hemp or silk yarn.

But this is not the focus of Shu Hui's attention at all. He finally understood that the reason why people in this place had such a high incidence of stone gonorrhea was precisely because of this kind of eating habits that made people take it for granted.

Soybeans contain small amounts of oxalic acid. Although in the process of ordering tofu, some oxalic acid will combine with the calcium ions in the tofu to form insoluble calcium oxalate, and some will be dissolved in the water where the tofu has been ordered, and then filtered out of the tofu.

However, the tofu puree that has not been boiled at high temperature, without the process of evaporating oxalic acid, its soluble oxalic acid residue will be much greater than that of the tofu we are familiar with in later generations. And because the puree is not heated, the chance of oxalic acid binding to calcium ions is also greatly reduced.

Even, the bean juice filtered through the tofu is also a drink for the locals because it is relatively nutritious! ，

These soluble oxalic acids enter the bloodstream, bind to free calcium ions in the blood, nucleate and deposit in the kidneys. Slowly condensed, accumulating over time to form stones, which is what Yuan Tiangang and others called stone showers.

In fact, Shu Hui didn't know, but he was a little crooked this time. Even if the raw tofu is eaten for a long time, the average person will not have such a high incidence. In ancient times, blood relations in the same area were often frequent, and some genetic diseases were easy to spread in a certain area.

However, even if there are genetic factors, improving the tofu production process can reduce the incidence of local diseases, and patients who are already sick can suffer less.

Shu Hui thought that it was probably this primitive tofu that caused such a high incidence of stone showers in the local area, although he was not completely sure, but he should also say this idea. By the way, the improved process of northern tofu is the taste he is familiar with, which is beneficial to others and himself.

"Yuan Ming Mansion, there are frequent stone showers in Huojing, and I think it's mostly the reason for this." Shu Hui pondered the language and said slowly: "Before adding the brine, boil the filtered soybean milk first, and then order it into tofu, which may reduce the number of cases." ”

"Moreover, the tofu produced by this is firmer, and it is most delicious to use for deep-frying, soup, and dipping sauce." As she spoke, Shu Hui's focus turned to eating.

"After the soy milk is boiled, scoop it out of the hot pan, add brine or gypsum, and stir it to make a smooth tofu brain. This tofu brain is smoother and more delicate than the original tofu ordered with raw soy milk, and it is not loose when it is formed into a piece, so you can add more sauce. ”

Yuan Tiangang and Mu Quan were stunned when they heard this, how could this god have a foodie face? No, no, this is a new method of tofu invented by the gods in Pudu sentient beings, in order to save the people of this county from illness.

Yuan Tiangang decided to immediately send someone to try out the new method of tofu, if the taste is indeed as good as the prodigy said, then it will be easier to promote it among the people. Otherwise, even with the majesty of his county order, it would not be able to force the people not to eat tofu.

Mu Quan, as Gong Cao, is the main adjutant of the county order, and has a tacit understanding with Yuan Tiangang. Seeing Yuan Tiangang's reaction, he withdrew to prepare for the verification of the new method of tofu.

Soybeans are just beginning to pod, and there is still some time before they are harvested, but last year's aged beans can also be ground into tofu. In the past, it was to make tofu from new beans in order to make offerings to prodigies, but now it is not possible to do so.

To grind tofu, there are handymen in the county office who can do it. It's just that in this season, aged beans need to be soaked overnight before they can be used. In the prefecture taverns and restaurants, most of the tofu sellers only make it once in the morning, and there are no foamed beans now. If you want to verify it, you can only wait until the evening to start foaming.

It was rare to see Shu Hui say so many words, and Yuan Tiangang took this opportunity to ask for some numerology. In his opinion, Shu Hui is the prototype of Luoshu, the prototype of gossip, and I am afraid that no one in the world can beat the right in mathematics.

However, he was destined to be disappointed, and he was completely ignorant of what he said about the five elements gossip, the heavenly stems and the earthly branches, and the star palace Taixuan. But he didn't doubt Shu Hui's identity because of this, because Shu Hui was the body of Luo Shu in his eyes, which was older than these doorways derived from his image. If Shu Hui said that he didn't know, it was nothing more than two possibilities, one was that he didn't understand the way they described it, and the other was that they were mistaken.

On the contrary, for physiognomy, which seems to have nothing to do with the mechanism of Vena number arithmetic, Shu Hui is more enthusiastic.
