Yu Yuanzheng then noticed that besides Liu Yunshu, there was another woman in the room whose attire revealed she was the queen's wife.

"Dr. Zeng, this is the Queen Mother." When Prince Liu saw Yu Yuanzheng looking at his Queen Mother, he immediately introduced her.

Seeing her son being so polite to her, Empress Liu immediately knew that this miracle doctor was no ordinary person.

"Greetings to the Queen of Nanshu. Best regards, Queen."

Shangguan Ziqi and Cao Jinyu also stepped forward to greet him.

"Divine doctor, is there any way to cure the emperor?" Empress Liu asked in a gentle voice.

"I have already thought of a solution, using steaming to detoxify." Yu Yuanzheng happily said the solution she had thought of.

But everyone was confused after hearing it.

"What is steam steaming?" Prince Liu asked when he didn't understand.

“Have you seen steamed buns?”

“Never.” How could Prince Liu, as the crown prince of a country, possibly know anything about kitchen matters?

"You must have seen people selling buns on the street, right?"

"I have seen that. Are you saying that we should steam our father like a bun? How about that?" Prince Liu objected immediately.

Thinking back to the moment when he saw the steamed buns coming out of the steamer on the street, he was furious. He knew at a glance that they were very hot. How could anyone bear it?

"Your Highness, please don't misunderstand me. The steam I'm talking about is of course not that high in temperature. It is controlled at a temperature that the human body can withstand, which makes people sweat and expel toxins from the body.

If you come a few more times, the water in your body can be completely replaced. But the emperor will definitely have to suffer some pain, and he can only endure this pain for the sake of curing his illness." Yu Yuanzheng explained.

"I understand. Okay, let's try it as you say." Prince Liu decided on the spot.

This treatment, which does not require medication, is definitely not dangerous.

"Father, you have heard it too. The miracle doctor has found a way to detoxify you. I hope you live a long life, so I made this decision." Prince Liu went to the bedside and told Emperor Zhi of Shu again.

Emperor Zhi of Shu looked at Yu Yuanzheng again.

"Your Majesty, don't worry. There is no danger at all. I am just trying it out. We have to try it to know whether it is useful or not. Based on my understanding, it should be useful."

"Okay, I'll try." He didn't want to die yet. He wanted to live to the age of his father.

His grandfather lived to be fifty, and he was still four years away.

It will be easy if we get the patient's consent.

Yu Yuanzheng asked Prince Liu to prepare a room that was sealed on all sides, leaving only one window for people to breathe.

This is not simple. This is the imperial palace. There is definitely no house so simple.

Then prepare now.

Prince Liu summoned the Minister of Works and asked him to build a small house outside the Yangxin Palace that met Yu Yuanzheng's requirements within one day.

The emperor didn't have much time left, and all the ministers knew about it. His Royal Highness the Crown Prince actually invited a miraculous doctor from another country to treat the emperor.

After hearing about it, some ministers rushed into the palace to find out what was going on.

Can we trust this doctor from another country?

Everyone thinks so.

Since they were invited by the Crown Prince, they could not raise any objections.

Except for one person.

The Crown Prince's maternal grandfather, the Prime Minister, entered the palace first.

"Your Highness, have you investigated the doctor you invited? How good are his medical skills? Will he harm the emperor? I heard that he is from Wei. He is not from Southern Shu. Why didn't you discuss it with me before inviting him?"

The Prime Minister was afraid that his grandson would do something wrong, so he couldn't afford to make any mistakes at such a critical moment.

"Grandfather, rest assured. The doctor you invited is the most famous doctor in Wei. He is also your and your sister's lifesaver. If he wanted to harm my father, he would not have let you get away easily after knowing your identity.

Moreover, he is the adopted son of Prince Jing of Wei. Based on this identity, he dare not act recklessly.

Otherwise, it will lead to hostility between the two countries. Now that Wei is at war with Canglan, they dare not make enemies with us again."

Prince Liu explained the whole story clearly.

After listening to this, the Prime Minister thought deeply for a while and felt that it made sense, so he gave up and told him to continue to watch Dr. Zeng for treatment.

Then several ministers and princes entered the palace, and they were all persuaded by the prime minister and the prince. No one wanted to leave the palace and asked to watch.

Yu Yuanzheng doesn't have high requirements. It's summer now and the weather is hot.

The house was built in less than a day.

Yu Yuanzheng asked the imperial kitchen to bring in a few covered jars, and had Shangguan Ziqi use a stone to knock a small hole in the side, then insert a bamboo tube, the other end of which led to the small house, and then seal the hole with mud. Then he lit a fire under the jar and started burning.

Several vats were heated at the same time until the water boiled and steam came into the house.

Yu Yuanzheng went to the small house in person to feel where the temperature was just right.

Once the steam maintains a dynamic equilibrium, the temperature generally does not change much.

That is, the old steam is cooling down naturally and new steam is replenishing it.

In fact, it is the same principle as a sauna, but it is simpler.

After the position is determined, someone will open a small window so that the patient can stick his head out to breathe the cool air outside.

"Your Highness, it's ok, can you help the Emperor out?

Everyone, if anyone wants to try it, you can go in with the emperor. This sauna has many benefits.

It can remove external evil and dampness, dredge the meridians, purify the blood and detoxify, reduce weight and beautify the skin." Yu Yuanzheng promoted it to the ministers who were watching.

"The Queen Mother will personally accompany father in." Crown Prince Liu took the initiative.

"OK."

"Prince, I will go in too." The Prime Minister also wanted to follow him in.

"Old Prime Minister, you'd better not go in. You are too old. I'm afraid your heart can't take it. When a person is hot, the blood circulation will speed up." Yu Yuanzheng stopped him.

"Oh? There is such a saying?"

“Yes, it’s best not to enter if you are over 60, unless you feel your heart is in good condition, then there will be no problem,” Yu Yuanzheng emphasized.

Emperor Zhi of Shu was helped out, and Crown Prince Liu personally carried him into the sauna room.

As soon as he entered, the heat hit him in the face. Yu Yuanzheng followed him in.

The two men almost fainted, and the Emperor of Southern Shu's breathing became a little obstructed, and his expression quickly changed.

"Quick, stick the emperor's head out of the window." Yu Yuanzheng said anxiously.

Prince Liu was also quick in his actions. As soon as he put the person on the chair, he moved the head of the Shuzhi Emperor forward.

I feel better after breathing some fresh air outside.

"Okay, Your Highness, hold on, I'm going to go out."

As soon as he came in, he was sweating all over.

Yu Yuanzheng was a woman, with a cloth wrapped around her chest. She couldn't stand it at all, so she said something in a hurry and left.

Then go to the window outside and watch the Shuzhi Emperor's face change.

The first steaming time should not be too long, at most a quarter of an hour.

"Your Majesty, if you can't bear it, tell me now and come out immediately." Yu Yuanzheng did not forget to instruct.

"Um."

The steam temperature inside is at least around 60 degrees, and most people who experience it for the first time can't stand it.

Time passes by little by little.

The face of Emperor Zhi of Shu began to turn red.

And Prince Liu, who was with him, was already covered in sweat.

He supported the emperor with one hand and quickly took off his shirt with the other hand.

"Father, can you bear it?" Prince Liu asked with concern.

He himself understood it very well. What he wanted to do most now was to get out as soon as possible because it was too hot.
