Soon, the crown prince was sent to a quiet room, except for Sun Simiao and Li Yuan, all the people who served around him were ordered not to come within a few hundred steps of the quiet room.

This degree of rigor is far higher than that of Li Yuan himself.

Although the elderly Li Yuan is similar to many old people, he inevitably becomes confused and willful, and even for an emperor, it can be said that he is a little mediocre.

But about Li Chengqian's foot disease, Li Yuan is still very clear, and to put it mildly, this matter involves the national capital of the Tang Dynasty.

From ancient times to the present, only the emperor is lame, and the prince has not been lame!

It is absolutely impossible for the empire to choose a certain lame heir as emperor!

If the emperor accidentally lames for some reason after ascending the throne, although this problem is not small, it is harmless. Even the government and the opposition will avoid it.

But there has never been a time to choose a physically disabled prince to be the emperor!

If this is the case, then ...... Tai'er....Although Li Yuan is dying, his basic qualities as a political figure are still there, and in an instant, he thinks of a lot in his mind, such as who is the most likely among the princes, or the forces behind the princes, etc., this kind of political consideration is simply engraved in his bones.

And Li Chengqian, as the person concerned, also forgot Fang Cai's anger and shyness at this moment, and replaced it with deep fear.

Regarding his foot disease, although he has a non-existent attitude on the surface, and in his daily life, he tries his best to make himself like a normal person, and in order to show his normality, he will deliberately show his martial arts and equestrian skills in front of his parents and ministers.

But his own body knows that this little boy who has repeatedly made him a little unhappy and who was designated by his brother as his prince's concubine actually explained the symptoms of his foot disease clearly without looking at his legs and feet, and his prediction of his illness directly hit the biggest fear in Li Chengqian's heart all along.

You know, this Chaosanlang is the one who rescued his dead grandfather, and his medical skills are so strange that even the imperial doctor and Sun Daoye are amazed, and he says so, I am afraid that he is the crown prince.

I hope he can cure the lonely-footed disease.

At this moment, he no longer had the slightest anger and jealousy in his heart for this Chaosanlang, the first prodigy of the Tang Dynasty in the mouth of the adult, Qilin'er, but instead of deep fear and expectation.

With trepidation and anticipation, Li Chengqian laboriously took off his boots and stretched out his feet tremblingly.

Lu Zhe, who was sitting opposite him, was not much less worried in his heart at the moment than Li Chengqian opposite!

I hope it is as I speculated, Lu Zhe repeated in his heart.

After Lu Zhe repeatedly and carefully examined under the nervous gaze of the people opposite and around him, he closed his eyes and carefully recalled and scrutinized.

In the quiet room, everyone stared with bated breath, and the atmosphere did not dare to come out.

Suddenly, he opened his eyes, got up and arched his hand at Sun Simiao, and gave up his position.

"I'm tired of His Royal Highness the Prince of Daochang Sun."

"Okay." Sun Simiao didn't say much, stroked his long beard, sat down in front of the bed, and carefully gave the prince a pulse.

"How's my foot disease?" It was a female voice who spoke, and Empress Eldest Sun didn't know when, so she stood behind her.

"I've seen the Queen." Lu Zhe and Sun Simiao hurriedly greeted Empress Changsun.

"The Taoist doesn't have to be polite." Empress Eldest Sun hurriedly asked Sun Simiao to sit down, "I've seen the emperor." Empress Eldest Sun blessed Li Yuan.

"Hmm-" Li Yuan waved his hand, in response. "Be polite."

It turned out that Empress Changsun arrived at Li Yuan's bedroom a quarter of an hour ago, and when she saw the formation outside the door, coupled with the female official's previous description, she knew that this matter was not light, so she also asked the accompanying female officer to wait outside and come in alone.

When I came in, I saw my son leaning on the couch with a panicked face, and the Tang Qilin'er was carefully watching his feet. Her mind turned sharply, and Empress Changsun probably guessed the whole thing, so she didn't dare to disturb in her heart, so she had to stand quietly a little farther away and wait for the result.

When Sun Simiao gave Li Chengqian a pulse, Li Yuan had already relayed what Lu Zhe had just said to the eldest grandson, and when the eldest grandson queen heard it, her body trembled slightly, and then she forcibly held back and quietly waited for the result.

"How's my child's illness?" After Sun Simiao's pulse was finished, Empress Eldest Sun asked anxiously.

Sun Simiao didn't speak, he muttered to himself, and seemed to notice that something was wrong, so everyone looked at Lu Zhe.

"Ruozhe expected to be right, the prince's foot is sick, and the disease is not in the muscles and bones, but in the viscera! The Prince's patient is a thirst-quenching disease, and this foot disease is a precursor to thirst-quenching disease! ”

"Thirst-quenching!" Sun Simiao's eyes lit up, and then he spoke, "The prince's pulse is peaceful, but the liver qi is stagnant, the yin deficiency is vigorous, the three scorching are fierce, and the five internal organs are dry. ”

"Dare to ask the prince, do you drink a lot of water on weekdays, and do you often feel thirsty," Sun Simiao asked solemnly.

"For a day, you need to drink two liters of water... I also feel thirsty. Li Chengqian's voice trembled, and he had to tell the truth at this moment.

"Thirst quenching!!" Empress Eldest Sun and Li Yuan glanced at each other, both with some fear in their eyes.

In ancient times, diabetes was called thirst-quenching disease, and polydipsia, polyuria, polyphagia, weight loss, fatigue, and sweet urine were the main ones (how do you know the last item, guess?). In the eyes of the ancients, thirst was also regarded as a serious illness, but it was not a terminal illness. However, most of those who suffer from thirst disease are difficult to cure, and for the ancients, it was also a lifelong disease (just kidding, modern people can't cure diabetes).

How did Lu Zhe guess Li Chengqian's diabetes? The reason is that a person he knew in his later life also suffered from diabetes, and in the early stage of diabetes, there was a symptom, that is, diabetic foot, as long as it broke a little skin, it first ulcerated, blackened, and then stiffened and unconscious, and many people would even be amputated.

And the person Lu Zhe knows is suffering from diabetic foot, and his walking posture on weekdays feels quite similar to Li Chengqian!

Lu Zhe, who was just looking at the palace maid, was asked by Li Yuan, and when he was in a panic, he saw Li Chengqian, I don't know why, he suddenly remembered the acquaintance in his previous life, Lu Zhe's heart flashed, is it not this prince's foot disease, it is just this diabetic foot, thinking of Li Shimin's lineage, almost everyone has this disease, Li Yuan, Li Liqing, Li Shimin all suffer from this disease, thinking of this, the more Lu Zhe thinks about it, the more likely it is, so he blurted out.

When he saw a slightly blackened black spot on the soles of Li Chengqian's feet, Lu Zhe could almost be sure that the feet of the crown prince Li Chengqian were exactly the same as the feet of the diabetic patient he saw in his later life! It wasn't until that moment that Lu Zhe's heart was slightly better.

When the medicine prince was sure that Li Chengqian was thirst-quenching disease, Lu Zhe's heart could be regarded as completely relieved.

In this era, there are only two people in the world who can completely determine whether a person lives or dies.

One is Sun Simiao, and the other is Li Shimin.

Seeing that the medicine prince said this, Li Yuan's face became more and more solemn, and Li Chengqian's face turned pale, and he didn't know why.

Astound! The eternal mystery of Li Chengqian, the prince of the Tang Dynasty, turned out to be like this! Lu Zhe's face was dignified on the surface, but there was even a sense of satisfaction in his heart that he had seen the secrets of the ages.

This kind of satisfaction belongs exclusively to our glorious melon-eating masses.

Oh, forget that at this time there was no watermelon in the Tang Dynasty, although as early as the Han Dynasty Zhang Qian brought back watermelon, called cold melon, in this era cold melon is a tribute to the Western Regions, but because the watermelon at this time has not been completely tamed and improved by humans, the flesh inside is white, and the taste is not sweet, so no one in the royal family eats it. Thinking of this, Lu Zhe missed the crispy red watermelon very much.

Tsk, Lu Zhe, who was now incarnated as a melon-eating crowd, looked at Li Chengqian's slightly pale face at the moment, and remembered that this person was only seventeen or eighteen years old, and he was under pressure that his age should not bear at any time, and he had to sigh secretly in his heart.

"Brother can only help you get here." Thinking of the home remedies found by an acquaintance in later generations, Lu Zhe slowly spoke.

"The emperor, the queen, this prince's foot disease is not unthinkable." Lu Zhe opened his mouth weakly.

"What!" Li Yuanhu was stunned and turned his head to look at Lu Zhe.

"Little gentleman can have a cure."

"Please also ask Asan Lang to save my son." For the sake of her own son, the eldest grandson queen actually bowed down. Frightened, Lu Zhe hurriedly shouted that Hugh was so, and the queen asked to get up.

"This thirst-quenching disease can also be cured by Xiaoyou?" Sun Simiao looked at Lu Zhe at this time, and his eyes couldn't help but stare at Lu Zhe.

"Well..... everyone, don't be impatient. What the philosopher said is conceivable, not a cure, and the Taoist must also know that this thirst-quenching disease is half carried in the womb, and half is caused by the acquired fat and sweet taste, which is difficult to cure. Although the prince's foot disease is a precursor to thirst-quenching disease, the symptoms are mild, and if it is properly recuperated, his foot disease can also be eliminated. ”

"Please also explain how to treat Asamaro." When Empress Changsun heard Lu Zhe's words "difficult to heal", she felt a little desperate in her heart, but when she heard the words later, hope ignited in her heart again, so Lu Zhe just finished speaking, Empress Changsun ignored the queen's demeanor and spoke first.

"Well, according to what I got in my dream, His Royal Highness the Prince, I will have to suffer some hardships in this life." Lu Zhe turned his head to look at Li Chengqian, who was in shock, and an indescribable feeling surged in his heart.

If he really recuperates Li Chengqian's foot disease, then what will happen to the history that has changed?
