As soon as Zhang Nan heard this, he already knew in his heart that this was really taking his life to work, his own health was not good, and he had to work at least fourteen hours a day, even if he was a normal person, he would be tired and sick, not to mention this Du Ruhui, who had heart disease and high blood pressure, this was simply asking for his own death.

"Then why don't you persuade Master Du? Knowing that he was sick, he still tolerated him overdrawing his body at will. Zhang Nan said with some reproach.

"Master, this really doesn't blame us, everything in our family is decided by my father, he wants to work, and none of us can persuade him." At this time, Du He stood up and said.

After Li Er heard this, he sighed with emotion, and then said: "Keming is really the pillar of the country." ”

"Okay, Your Majesty, if you want our pillars of the country to live for two more years, just give Lord Du a long vacation, and force him to go out for a spin, don't work at home for a day, it's best to let Lord Du rest for a year and a half, otherwise if you continue to do this, the next time you get sick, it will be really difficult for the gods to save you." Zhang Nan said solemnly.

"Is it that serious?" Li Er saw Zhang Nan's solemn appearance and asked with a strange expression.

"Yes, and I can only say that this is still the most ideal situation, Lord Du is now overdrawing his life at work, this sudden heart attack is a proof, if I didn't give Lord Du a fast-acting effect and let Lord Du breathe oxygen bags today, Lord Du is estimated to have passed today." Zhang Nan nodded and said.

In fact, what Zhang Nan said is not wrong, the real history of Du Ruhui is Zhenguan died in the fourth year, as for whether it is this time, Zhang Nan does not know.

However, Zhang Nan felt that it was probably because Du Ruhui did not cherish his body and overdrew himself at will, and the medical facilities in the Tang Dynasty were not good, so Du Ruhui died after continuous high-intensity work, high blood pressure and heart disease.

"In that case, then I will allow Keming to recuperate at home and distribute everything as usual, and I decree that Keming will not be allowed to interfere in government affairs anymore, and I will talk about it after he recovers." Li Er thought about it, and decided to let Du Ruhui live an early retirement life first.

After all, no matter how important the work is, Li Er's talents are abundant, and he must be able to find someone to share it, but Du Ruhui is only one, if Du Ruhui is tired to death at work, then Li Er will not be able to forgive himself for the rest of his life.

As soon as she heard Li Erdu's order, Mrs. Du immediately saluted Li Er excitedly and said, "Thank you to the emperor on behalf of the concubine." ”

Li Er nodded and said, "Eh, Keming, he will hand it over to you, when I have nothing to do, I will also come to accompany Keming, hey, it's all my fault, I put so many burdens on Keming." ”

Just as everyone was talking, Sun Simiao stepped into the inner hall and saw Comrade Li Er there, Sun Simiao hurriedly saluted Li Er.

"See the Emperor." Sun Simiao said.

Li Er saw Sun Simiao coming, and said, "Sun Zhenren doesn't need so many courtesies, hurry up and give Keming a look at the disease, my group of imperial doctors...... Eh, don't say it, Sun Zhenren should hurry up and show Keming. ”

When Sun Simiao heard this, he hurriedly walked up and began to prepare to give Du Ruhui a pulse, Zhang Nan also gave a place to Sun Simiao, Sun Simiao nodded, and said hello to Zhang Nan, although Sun Simiao was very interested in the new drugs and medical devices that Zhang Nan took out, but this is not the time to ask this.

After a while, Sun Simiao said: "Lao Dao thinks that Master Du should be a respite. After speaking, he found that no one responded, and when he looked up, he found that everyone was looking at him with a confused face, and Sun Simiao realized that everyone didn't know what the gasp was.

"No, I think Master Du has a heart problem, not a lung problem, and it's not that Lord Du has a lung problem, but the main reason is a heart problem." Zhang Nan said with a strange face, could it be that he guessed wrong?

"That's right, this asthma is a heart problem." Sun Simiao nodded.

In fact, the so-called asthma syndrome in ancient times is today's heart failure, so Zhang Nan's guess is not bad at all, Du Ruhui has heart disease.

"Let's go out and talk, give Lord Du a quiet environment, and I'll prescribe another prescription for Lord Du to recuperate." After Sun Simiao finished speaking, he stood up.

"I'll stay with my father, mother, go and rest, you haven't closed your eyes for a few days." Duhe said.

"That's right, mother, go and rest, it's enough for me and my second brother to be here." Du Wei said.

Du He and Du Gou took care of Du Ruhui in the house, and Mrs. Du also went to rest after greeting Li Er, she was too tired.

Since Du Ruhui complained about her illness at home, Mrs. Du couldn't eat or sleep well, especially when Du Ruhui's condition deteriorated, Mrs. Du stayed by Du Ruhui's side step by step, and now she can finally rest.

Zhang Nan left four oxygen bags for Du He, and after telling Du He how to use this thing, he told him that he must be like Du Ruhui before he can use this thing after he can't breathe like just now.

It's not that Zhang Nan feels sorry for these oxygen bags, it's just that Zhang Nan is unwilling to let Du Ruhui develop oxygen dependence, and Zhang Nan doesn't want Du Ruhui to keep the oxygen bags in the future. After finishing speaking, Zhang Nan followed Li Er and Sun Simiao out.

"Little friend, what is that bag you just made?" After Sun Simiao wrote the prescription and the doctor's instructions in detail, he couldn't wait to ask, now Sun Simiao is becoming more and more curious about Zhang Nan, except for Zhang Nan's medical methods, just this endless stream of things that can cure diseases and save people makes Sun Simiao curious.

"Oh, that thing is called an oxygen bag, and it contains oxygen, which can help patients who are having trouble breathing." Zhang Nan said.

"Nourishing Qi? What is Qi Cultivation? Can Qi also be used to nourish it? Sun Simiao asked strangely.

Seeing Sun Simiao, who was a novice in modern common sense, Zhang Nan had no choice but to explain Sun Simiao in detail.

"This oxygen is the gas we breathe into the body, in fact, in the air around us, there are nitrogen, oxygen, rare gases, carbon dioxide and so on in the body, but the only thing that can be used by us is oxygen, so we will exhale, and the breath exhaled is the gas that our body does not need." Zhang Nan said.

"Little friend, how did you find out? There are so many types of qi around you, how can you tell the difference? Sun Simiao asked with perseverance, now that Sun Simiao has entered the medical Tao, he has become a medical idiot, and Sun Simiao is interested in everything related to medicine.
