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

As soon as Li Mingbo finished speaking, he felt as if he were flying again.

Upon seeing Cheng Yaojin's憨憨 (simple-minded) face with its thick beard, glaring at him like a bull, with "hot air" billowing from its nostrils wide enough to stick a finger into, he angrily asked Li Mingbo, "Are you telling the truth?"

Why does this silly guy always like to pick people up?

"General Cheng, you didn't believe me, so I was just saying it casually. Don't take it seriously," Li Mingbo said with a wry smile, pointing at the arm that was holding him with his finger.

"Heh, you're still holding a grudge?" Cheng Yaojin put Li Mingbo down with a dark face and patted Li Mingbo on the shoulder.

"General Cheng, are you trying to kill me? You're the one who holds a grudge." Seriously, I almost vomited blood.

Li Mingbo quickly moved away from this silly guy.

Thinking of Cheng Yaojin's relationship with Qin Shubao, Li Mingbo's heart softened, and he continued, "General Cheng, that's indeed the case. Historical records show that the Duke of Yi did indeed die in the 12th year of Zhenguan, two years after Empress Zhangsun."

Then, Li Mingbo flew up again, this time not by Cheng Yaojin, but by Li Shimin.

Li Shimin was an emperor who rose to power on horseback, not a pampered one; his strength was in no way inferior to Cheng Yaojin's.

Li Mingbo was held tightly by Li Shimin's hands around his neck, his feet off the ground.

Li Mingbo suddenly couldn't breathe, his legs kicked wildly, his face turned purple, and he coughed loudly.

Let go!

Li Mingbo struggled.

Damn it, I miscalculated.

He had forgotten that Li Shimin and his wife, Empress Zhangsun, were a loving couple.

Revealing Empress Zhangsun's death date to Li Shimin was practically suicide.

It seems I need to think twice before I speak in the future, instead of being as casual as I was in modern times, saying whatever comes to mind.

What is an ordinary event in modern times becomes a momentous event here.

"Your Majesty, Your Majesty."

Cheng Yaojin, being loyal, feared that Li Shimin might lose his temper and strangle Li Mingbo, so he came over and loudly spoke to Li Shimin.

Li Shimin then put Li Mingbo down and said coldly, "Speak, what exactly happened when you said the Empress was two years younger than Shubao?"

Li Mingbo instantly felt the air in the entire hall suddenly drop, and Li Shimin's cold gaze was like a biting wind blowing towards him.

This is the meaning of "When an emperor is angry, millions will die."

This is the emperor.

Keep your word.

Li Mingbo swallowed hard and looked at Li Shimin, saying, "Your Majesty, I was just an ordinary person over there. I like to read some history and learned some things by chance online. The Empress did indeed die in the tenth year of the Zhenguan era."

"Call it a mess!" Cheng Yaojin said disdainfully from the side.

"Oh, I'm sorry, there aren't so many rules anymore after more than a thousand years, so I didn't know." Upon hearing this, Li Mingbo realized that there was a specific term for the death of an empress: "collapse."

That's embarrassing.

"What is the cause of the illness?" Li Shimin asked.

"It seems to be a respiratory illness. Oh, here it's called 'breath disease.' There are various theories online. Some say it's caused by heart disease, while others say it's a hereditary disease. Princess Chang Le passed away on August 10th of the 17th year of the Zhenguan era at the age of 23, and it seems to have been caused by heart disease as well."

"And Princess Jinyang, who apparently died of illness at the age of twelve."

"Princess Jinyang?" Upon hearing this, Li Shimin realized that his princess did not have this title.

"Yes, the little princess is an idol in our area, very popular. Oh, by the way, her name is Li Mingda, nicknamed Sizi. She is the little princess born to His Majesty and the Empress," Li Mingbo said.

"My youngest princess is named Chengyang, and she is only three years old this year," Li Shimin said.

"What year was Princess Jinyang born?" Li Mingbo muttered to himself.

If Li Shimin says no, then the child must not have been born yet.

"Can you cure the Empress's illness?" Li Shimin asked Li Mingbo in an almost pleading tone.

"Your Majesty, I am not a doctor and do not know how to treat this," Li Mingbo said. "But..."

It's okay if there's a "but".

There may be no buts.

When Li Shimin heard Li Mingbo say "but," he felt a sense of relief and hope.

"You brat, from now on, just say what you mean at once," Li Shimin said, glaring at Li Mingbo.

"Yes." When Li Mingbo heard Li Shimin scolding him, he felt that this meant Li Shimin considered him one of his own.

I was very happy.

This is the biggest leg.

As long as you hold on tight to this leg, nothing else matters.

"Although I am not a doctor, I can take a look. Some illnesses are caused by external factors, such as pollen allergies. Also, the ash from burning charcoal in winter is very important in triggering the illness."

"I saw what I'm saying on the internet over there."

Li Mingbo said.

"Did you see this on the fishing website?" Li Shimin asked.

"No, Your Majesty, this is technology from over a thousand years in the future. You wouldn't understand even if I explained it to you. It's the kind of thing I mentioned earlier that has clairvoyance and clairaudience." Li Mingbo held up his phone.

"We'll discuss your request tomorrow morning," Li Shimin said.

At that moment, the door was pushed open, and a tall, thin man with a sallow face, wearing gleaming armor, walked in.

"Your subject, Duke of Yi and General of the Left Guard, Qin Shubao, greets Your Majesty," the sallow-faced man said, bowing to Li Shimin.

"Second Brother Qin, please have a seat." Li Shimin pointed to the carpet in the hall when he saw Qin Shubao.

Qin Shubao expressed his gratitude and sat down on the ground.

"Boy, you saw it too," Li Shimin said, looking at Li Mingbo.

Li Mingbo ignored Li Shimin.

Instead, he carefully examined the sallow-faced man.

Is this the great hero in my heart?

It would be no exaggeration to describe him as extremely thin.

"Your Majesty, who is this person, and how dare they be so rude?" Qin Shubao asked Li Shimin.

"This humble one, Li Mingbo, greets General Qin!" Li Mingbo solemnly approached Qin Shubao, cupped his hands, and said.

"Mm," Qin Shubao nodded in response.

That's when everyone learned Li Mingbo's name.

Qin Shubao looked at Li Shimin with a strange gaze.

Could it be His Majesty's brother in her heart?

But he didn't dare ask.

Seeing the respect mixed with regret in Li Mingbo's eyes towards his Second Brother Qin, Cheng Yaojin seized the opportunity to ask, "Li Mingbo, in modern times, could you cure Second Brother Qin's illness?"

"You mustn't be rude. My illness is incurable." Qin Shubao rolled his eyes at Cheng Yaojin.

Why bring me up on such an important occasion?

Even Changsun Wuji, the Empress's own brother, didn't come in, nor did Fang Xuanling, and even the rising star Yuchi Gong wasn't allowed in.

"General Qin's illness is easier to treat than the Empress's. I've seen some information online that General Qin's illness is mainly due to excessive blood loss on the battlefield in his early years, which did not receive timely treatment. He didn't feel anything when he was young, but as he got older, his body's blood-producing function declined, leading to blood loss anemia. With blood transfusions and dietary therapy, I think the effect will improve quickly."

"General Qin, what I'm about to say may have been a bit abrupt," Li Mingbo said, bowing to Qin Shubao.

"No problem, speak freely, I will tell you everything I know."

"Does General Qin often suffer from severe back and leg pain, insomnia, and frequent awakenings at night...?" Li Mingbo asked.

Having seen countless people, Qin Shubao knew that the young man in front of him was acting out of kindness. Besides, Li Mingbo's surname was Li, and Qin Shubao didn't know if he had any connection with the royal family.

Therefore, they dared not offend them.

Seeing the regret in Li Mingbo's eyes, Qin Shubao told Li Mingbo about his illness.

Li Mingbo listened and repeated the words, recording it on his phone.

Li Shimin did not stop him, so Qin Shubao did not say anything.

"I just heard you mention blood transfusion, did I hear that right?" Cheng Yaojin asked after Li Mingbo finished taking notes.

"That's right," Li Mingbo replied.

After Li Mingbo finished speaking, he noticed that the three people were looking at him.

Li Shimin and Cheng Yaojin knew that Li Mingbo was a person from more than a thousand years later, so they were somewhat prepared.

But Qin Shubao didn't know that.

"Can the Empress's illness be cured through blood transfusion?" Li Shimin stood up and asked Li Mingbo.

"Your Majesty, these are two different things. The Empress suffers from a chronic respiratory disease, while General Qin suffers from hemorrhagic anemia. Anemia can be improved with blood transfusions and dietary therapy."

Seeing no hope, Li Shimin became anxious and paced back and forth in the main hall.

Suddenly, Li Shimin collapsed to the ground, convulsing uncontrollably.

Cheng Yaojin was the first to rush forward and try to pick up Li Shimin, but Cheng Yaojin also started convulsing.
