My house's electrical wiring dates back to the Tang Dynasty.

Soon, two palace maids, as beautiful as lotus flowers, entered and bowed respectfully to Li Shimin and Empress Zhangsun, saying, "This servant greets Your Majesty and the Empress."

"No need for formalities," Li Shimin said coldly. "I summoned you two here because there is a very important matter concerning whether the Empress can recover. I entrust this to you two." Li Shimin said, looking at the two palace maids.

"Your servants obey." The two were overjoyed to hear that such an important task had been entrusted to them.

"Listen to him, and don't overlook any detail. Otherwise, if anything happens to the Empress, even exterminating your entire family wouldn't be enough. Do you understand?" Li Shimin reminded him.

"We understand," the two replied, bowing.

"Can you read?" Li Mingbo asked, looking at the two beautiful women.

Both palace maids were dressed in thin Hanfu. When they raised their hands, their sleeves tucked in, revealing their snow-white arms and slender fingers.

"We can read," the two replied.

"Let me explain the operating procedure to you. First, let's get to know this medical device. This is called a portable oxygenator." Li Mingbo thought for a moment and realized that the other party probably didn't know what "ECMO" was, so he had to omit it.

Portable ECMO oxygenation, also known as extracorporeal membrane oxygenation, is mainly used to treat patients with severe cardiopulmonary failure.

Its core principle is to draw blood out of the body, oxygenate it and remove carbon dioxide through an artificial membrane lung, and then return the oxygenated blood to the body to temporarily maintain the oxygen supply to the organs.

To figure this out, Li Mingbo and Zhou Shuhan practiced operating it for several days at their hospital.

Later, Li Mingbo directly purchased one.

The main purpose was to prevent the Empress from suddenly experiencing cardiac and pulmonary arrest.

They wouldn't understand even if I explained it to them, but I still need to let them know about it so that we can protect it.

"This thing is the Empress's life-saving item. If the Empress suddenly has difficulty breathing and can't breathe, this thing can breathe in place of her body," Li Mingbo said.

"Breathe in place of the Empress? That's amazing!" Li Shimin asked upon hearing this. "Does that mean the Empress will be alright then?"

"That's right," Li Mingbo said. "With this, if the Empress has difficulty breathing, it can be used to temporarily replace her body."

"However, the operation is too complicated. Even if I teach you, you won't know how. I have to do it myself. It took me several days to learn it."

Li Mingbo's words were a bit serious, and it was something he had to do himself.

This is called a monopoly.

Let's see if Li Er dares to kill me again.

Seeing Li Shimin's curiosity, Li Mingbo explained the working principle to him.

Li Shimin looked at all these tubes, some of which represented the Empress's heart, and that blood would be drawn from these transparent tubes.

"I've already downloaded the video, and I'll show it to Your Majesty and the others in a bit," Li Mingbo said.

Then he explained to the two palace maids how to use a home oxygen concentrator.

This method is simple to use; I can teach it to them.

And the instructions on how to use those 24 oxygen cylinders.

At the same time, a lot of medical supplies were transported and stored.

After finally finishing talking about Empress Zhangsun, he took out the dietary therapy prescription.

List of foods to avoid:

1. Triggering substances: mutton, goose meat, shrimp, and crab. These foods promote histamine release and worsen asthma.

2. Irritating foods: pepper, dogwood, alcohol. These can induce intestinal mucosal bleeding.

Medicinal diet therapy:

Morning: Donkey-hide gelatin and bird's nest porridge, to replenish iron and nourish the lungs.

Lunch: Steamed sea bass with poria and yam, which strengthens the spleen and stops diarrhea, plus high-quality protein.

Afternoon: Probiotic yogurt (yogurt + lactobacillus) to repair gut flora.

Dinner: Rehmannia and Angelica sinensis black-boned chicken soup, to correct anemia and regulate immunity.

The list has been translated into Traditional Chinese characters.

Furthermore, Li Mingbo translated some items into Tang Dynasty names, while others did not exist in the Tang Dynasty, such as chili peppers, which are still in the Americas today. Li Mingbo removed these from the translations.

Many things have the same name. For example, pepper is still available in Chang'an, but it is a rare imported product and is extremely precious.

However, there is a Tang Dynasty name that differs from the modern one.

For example, yam was called "shuyu" in the Tang Dynasty. However, to avoid the taboo of Emperor Daizong of Tang, Li Yu (whose name is homophonous with "Yu"), it was later renamed "shanyao".

Li Mingbo brought over specimens of each type and labeled them.

The dietary therapy room was handed over to Empress Zhangsun.

As for how to cook the rest, Li Mingbo didn't care.

"Yes, I wronged you just now." Li Shimin saw how meticulous Li Mingbo was in his work and realized that he had wronged him.

"Your Majesty, you are too kind. Your concern for the Empress's health only proves that your love for her is deeper than the sea. I understand," Li Mingbo replied.

Li Shimin did this well.

For an emperor to apologize to himself is already quite rare.

It's important to understand that in feudal society, the emperor was never wrong; the only ones who were wrong were his subjects.

"It's so hot, Your Majesty. I need to start connecting the electrical wires," Li Mingbo replied.

Taiji Palace is located in a low-lying area, and it is July now, so the weather is hot and humid. After talking for a long time, Li Mingbo's clothes were already soaked with sweat.

"Treat the Empress's illness first, why are you connecting electrical wires!" Li Shimin kicked Li Mingbo to the ground.

"Your Majesty," Empress Zhangsun called out when she saw Li Shimin kick Li Mingbo to the ground.

"Your Majesty, I'm fine. A beating is a sign of affection," Li Mingbo said with a chuckle, rubbing his bottom.

The fact that Li Shimin could kick you directly shows that he considered you one of his own.

Didn't you see him kick Cheng Yaojin directly? Everyone else just drags him out to be killed.

"Hmph." Upon hearing Li Mingbo's words, Li Shimin snorted coldly and glared at Li Mingbo.

"Your Majesty, could you please ask me first next time? I'm also treating the Empress, aren't I?"

"Connecting the wires is to cure the Empress's illness. You'd better explain this to me clearly." He had personally experienced the discomfort of wires, and when he heard Li Mingbo say that connecting the wires was to cure the Empress's illness, he glared at Li Mingbo with a murderous look in his eyes.

"Your Majesty, do you see how many things I brought to treat the Empress's illness? How can they be used without electricity? Anyway, you wouldn't understand even if I explained, so just stand aside and watch."

"How dare you speak to me like that? I'll kick you to death." This kid is getting more and more arrogant, truly fearless.

"Your Majesty, we don't understand things from over a thousand years in the future," Empress Zhangsun reminded her.

"Hmph." Li Shimin snorted coldly and sat back down at his desk.

Li Mingbo opened a transparent plastic film and took out a bottle of classic Coca-Cola.

Li Mingbo bought 4 boxes.

With a soft "pop," it was unscrewed and handed to Li Shimin.

"You, you want to kill me?" Li Shimin's eyes widened when he saw the black liquid bubbling.

"Your Majesty, it's not that I won't give it to you if you don't drink it." Li Mingbo put away the bottle, tilted his head back, and gulped it down. "Wow—so refreshing!"

"Huh?" Li Shimin saw Li Mingbo tilting his head back and drinking, looking quite pleased with himself, while glancing at the Empress to the side.

Empress Zhangsun smiled slightly.

She knew that His Majesty was just being stubborn and was too embarrassed to ask Li Mingbo for it.

"Young Master Li, what is this? Is it delicious?" Empress Zhangsun asked on behalf of Li Shimin.

"This is a beverage, a thirst-quenching drink, even better than sugar water, but it's not suitable for the Empress's condition," Li Mingbo said, handing the black cola in his hand to Li Shimin.

When Li Mingbo was drinking, he didn't touch the bottle opening.

We were supposed to open a new bottle, but Li Shimin was worried about poisoning him, so we'll let you drink the one we drank before. That should be safe, right?

"Hmph." Li Shimin snorted coldly, took the bottle, and gulped down a large mouthful.

Millions of bubbles burst in my mouth, stimulating the oral mucosa, and a pungent sweet smell wafted out of my nostrils.

It tasted sweet, with an indescribable tingling sensation that rose from my throat all the way up to the top of my head.

"Uh—" Li Shimin, disregarding his imperial image, opened his mouth wide and burped, then exhaled a puff of air, looked at the black cola in his hand, and said, "This cola is really thirst-quenching, good stuff."

"Your Majesty, it tastes even better chilled," Li Mingbo said as he squatted down and opened the electrician's toolbox.

"Refrigerators?" Li Shimin, worthy of being called the greatest emperor of all time, looked at the two gray refrigerators that resembled coffins in front of him when he heard Li Mingbo say "freeze."
