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

"Li Lang, it's not that I don't believe you, it's just that, if I didn't know your identity, no one would believe it. Not to mention me, even if Doctor Sun came, he would say it's impossible," Qin Shubao said.

"Does 'Duke of Yi' refer to Sun Simiao?"

"What else?" Qin Shubao said.

"Sun Simiao is also very famous in modern times. He seems to have written two books called 'Essential Prescriptions Worth a Thousand Pieces of Gold for Emergency Use' and 'Supplement to Essential Prescriptions Worth a Thousand Pieces of Gold.' He was indeed a famous master of traditional Chinese medicine. I would like to meet him and give him something if possible."

Qin Shubao did not respond to Li Mingbo's question.

Such things are only for His Majesty to possess; he dares not get involved.

"Come, let me see what your blood type is, Duke Yi." Li Mingbo took the things, knelt down in front of Qin Shubao's table, tore open the packaging of the alcohol swab, used the alcohol swab to rub the tip of his ring finger, and then squeezed out a drop of blood.

Holding a disposable spring needle, he pierced the pad of Qin Shubao's ring finger.

The first drop wasn't ideal because of the alcohol. After testing it clean, I squeezed it out, then used a long dropper to draw up some more, and then had Qin Shubao press it down with a cotton swab.

"No need, this is nothing, not even as big as a mosquito bite." Qin Shubao wanted to laugh when he saw Li Mingbo's cautious manner.

And yet, someone still needs to hold the bleeding down?

Someone was wounded even more severely on the battlefield back then.

Next, Li Mingbo dripped the blood from the long dropper into hole A on the left and hole B on the right, filling the tube completely.

Then, use a short dropper to draw up the sample diluent and drop 5 drops into the middle D well.

Next, we'll have some time to spare.

As the diluted blood drips into the middle D hole, the blood in the left hole gradually fades until it disappears.

The blood in the B hole on the right side had not disappeared.

See the accompanying instructions.

"Duke Yi, you have type B blood," Li Mingbo said.

"What, what is closed blood?" Qin Shubao didn't understand the English letters at all.

"Oh, this is a language from over a thousand years later, much like our 'A' and 'B' or something. You can just treat it as a symbol," Li Mingbo said.

"So, should we call Huai Dao in next to give me a blood transfusion?"

"No need," Li Mingbo said, then explained to Qin Shubao, "Duke Yi, blood transfusions can't be done by simply drawing blood from a person. It has to go through strict processing to remove any viruses from the blood before it can be transfused into your body."

"Li Lang, I don't understand these things from over 1,300 years in the future. What do you suggest? I'll cooperate with you."

"I need to go back to the hospital to get the processed type B blood before I can have it transfused."

The blood needed for transfusion can also be directly transfused to the patient, but screening for infectious diseases such as hepatitis B, hepatitis C, AIDS, and syphilis is required.

In addition, the poor sanitation conditions and water pollution of the people in the Tang Dynasty, as well as their dietary habits such as eating raw fish, meant that if the blood donor carried a latent infectious disease, such as hepatitis B (called "jaundice" in the Tang Dynasty), or a parasitic infection such as roundworms or schistosomiasis, the parasites in the blood could enter the recipient's body through blood transfusion.

Direct blood transfusions can directly infect patients, leading to "unwarranted disasters."

The plasma used in modern hospitals undergoes multiple rigorous and professional processes, including blood collection, blood testing, blood separation, blood storage, and transportation, before it can be transfused into a patient's body.

Blood collection involves screening blood donors at the source, and those with a history of infectious diseases such as hepatitis B, HIV, recent surgery, or anemia will be excluded.

Blood testing includes: blood typing, infectious disease screening, and quality testing.

If the test fails, the blood will be disposed of in a harmless manner.

Li Mingbo then took out the blood collection plastic tube, drew a vial of blood from Qin Shubao, wrote his name on it, and put it away.

"I want to bring this blood sample back to the modern world for testing. Then the doctor will make a judgment, and I will buy plasma from the hospital to give to you, Duke Yi, for a transfusion." Li Mingbo told Qin Shubao his plan.

"Li Lang, thank you for your hard work. I, Qin Shubao, will remember your kindness. If you ever need my help in the future, just come to me." Upon hearing that Li Mingbo had made a special trip back to the modern world for his illness, Qin Shubao knelt down and bowed to Li Mingbo in gratitude.

This is a very important courtesy.

Apart from parents and the emperor, no one else could deserve such a bow from a duke.

"Duke Yi, please rise quickly. Are you trying to make me die even faster? I can't bear your bow." Li Mingbo quickly stepped forward to help the door gods up.

This is Qin Shubao, the famous door god.

I was laid off and started working.

"Ah, you have no idea how miserable I've been all these years. If you could cure my illness, it would be like giving me a second chance at life." Qin Shubao said with emotion after sitting up. "Thinking back to the past, I, Qin Shubao, can only stay at home and live like a sick old man. If it weren't for the fact that Huaidao is still young, I would have thought of slitting my throat with a knife. I'm suffering so much."

"Long live understanding," Li Mingbo nodded and said.

Qin Shubao's later years were quite miserable.

Even the 24 meritorious officials of Lingyan Pavilion could only be ranked last.

It should be noted that Qin Shubao had already made a name for himself during the Wude era.

After Qin Shubao decisively defeated Yuchi Jingde at the Battle of Meiliangchuan, Li Yuan personally issued an edict to comfort him, and said a very famous thing: "You disregarded your wife and children and came from afar to join me, and have achieved great merit. If my flesh could be used by you, I would cut it off and give it to you, let alone my children, jade and silk. You should strive to do your best."

In plain terms, it means that you disregarded your own wife and children, traveled a long way to seek refuge with me, and have accomplished such great deeds. If I have any flesh on my body that you can use, I will cut it off and give it to you to eat, let alone reward you with servants and wealth. You should continue your efforts!

He made great contributions under Li Shimin's leadership.

Whenever Li Shimin encountered a formidable enemy, he would send Qin Shubao into battle. Qin Shubao never disappointed Li Shimin, charging into the enemy ranks alone and taking their heads as easily as taking something out of a bag.

Unfortunately, he later fell ill and spent his time recuperating at home after Li Shimin ascended the throne.

Although he still holds the title of Left Martial Guard General, it is actually just a nominal position.

For a hero like Qin Shubao, such an ordeal was worse than death.

"Duke Yi, dying is not so difficult, but surviving is. Don't worry, I, Li Mingbo, swear to heaven today that I will definitely cure your illness, or may I be struck by lightning," Li Mingbo said.

"No need, no need to make such a solemn oath." Qin Shubao waved his hand gratefully when he saw Li Mingbo make such a solemn oath for him.

"Duke Yi, actually I have a question that people have been wondering about for over 1,300 years. I wonder if I could ask you?" Li Mingbo thought of a historical mystery.

"Just ask," Qin Shubao said directly when he heard that Li Mingbo had questions.

"Did you participate in the Xuanwu Gate Incident back then?" Li Mingbo asked, then explained, "Your descendants know some of what happened to you in your later years, and there are several different versions of the story. One version says that you were injured and had to stay at home to recuperate, while another version says that you refused to participate in the Xuanwu Gate Incident, and His Majesty intentionally neglected you."
