"Lao Dao also thought about this situation, but just now from the examination of Qingquan's head, there is no external injury." Sun Simiao said.

"Then when will Qingquan wake up?" Li Er asked, this is also a question that everyone present is most concerned about.

After hearing this, Sun Simiao shook his head and said, "This is not good, if you are lucky, maybe he will wake up in a moment and a half." But if you're unlucky, you won't wake up in ten days and a half months. ”

"Daochang Sun, do you mean that Lang Jun may not wake up? That's it for the rest of your life? Cui Yue was already desperate at this time, not long after the two children were born, it was the time for the husband and wife to face a new life together, and now Zhang Nan suddenly fell unconscious, which was definitely a big blow to Cui Yue.

"Yue'er, don't say that, didn't Daochang Sun say it just now? Maybe he'll wake up in the afternoon? No, don't be afraid. Jin Shengman also comforted on the side.

"Yes, yes, don't worry too much, Daoist Sun will definitely do his best to save Qingquan, right." Li Er twisted his face and asked.

"That's right, Mrs. Zhang doesn't have to worry so much, Lao Dao will open the top for Qingquan later, and at the same time stimulate Qingquan's acupoints with silver needles, Lao Dao will do his best." Sun Simiao also stroked the beard on his chest.

After all, Zhang Nan is not an exaggeration to say that he is a benefactor for Sun Simiao.

If it weren't for Zhang Nan, then Sun Simiao wouldn't know where to stay on that mountain now, where is it like now, not only eating imperial grain, but also being respected, since the cowpox turmoil, someone even set up a shrine for Sun Simiao outside Chang'an City.

And it is also because of Zhang Nan's emphasis on medicine, and the medical school established with the official support of Li Er has also improved the status of doctors in the hearts of the people in disguise.

Now every year when medical schools enroll students, there are many poor people who are willing to send their children to study medicine, although it is one aspect that they can have a job after graduation, but in the final analysis, it is because the social status of doctors has improved.

There is a child who is a doctor, and these parents also have a light on their faces.

From this point alone, Sun Simiao is still very grateful to Zhang Nan.

"Then it's troublesome for Daoist Sun." Cui Yue also gave Sun Simiao a salute.

"Madame doesn't have to be so polite." Sun Simiao said with a smile.

It was a mess outside, and Zhang Nan was very sober at this time, because Zhang Nan was talking to the system, but this upgrade of the system seemed to have brought a lot of changes to Zhang Nan.

"You're the system?" Zhang Nan looked at the virtual character in front of him who resembled the figure of a female star and supermodel in later generations, and wondered.

"As you can see." A sweet voice sounded in Zhang Nan's ears.

"How did you become human?" Zhang Nan was shocked, you know, the previous system simply provided exchange and query services, where is there such a highly anthropomorphic AI?

And many times when Zhang Nan asks questions about the system itself, the system only has one sentence of "the host authority is not enough" and passes it perfunctorily.

"Because the host you earn points, your influence in Datang and the comprehensive score of Datang's changes have reached the level of system upgrades, so the system has been automatically upgraded." The smile of the system made Zhang Nan not feel that it was a virtual artificial intelligence in front of him at all, but a real person.

"In addition to the appearance upgrade, are there any new features that are being opened?" When Zhang Nan heard about the upgrade, his first reaction was more powerful functions.

After all, no software will go up and down, and there will definitely be new features to be opened.

"There are a total of three upgrades in this upgrade, the first is that I can redeem more things here, considering the current stage of Datang's scientific and technological level, in order to help the host better complete the ultimate task, the exchange points of scientific and technological products in the transitional stage have been uniformly lowered a lot, and the host can exchange scientific and technological products according to their actual situation to help Datang continue to move forward."

Hearing the words of the system, Zhang Nan also nodded, this still sounds very good, after all, the points exchanged have become less, so Zhang Nan can exchange more epoch-making things to play.

"The second upgrade is that I have become highly anthropomorphic, with more intelligent ideas, which can better help the host solve problems that the host can't solve, and at the same time, the question and answer is more free, and the host can get answers closer to life." System Channel.

Speaking of this, this system, which resembles a certain female star in later generations, laughed.

"Then can you change your appearance?" Zhang Nan asked weakly.

"Of course, if the host likes it, I can turn into a rugged man."

Hearing the system say this, Zhang Nan's mind immediately appeared with a strong man talking to him in a loli voice, Zhang Nan immediately shook his head and threw this terrible idea out of his mind.

Seeing Zhang Nan's appearance, the system also chuckled.

Looking at such a system, Zhang Nan also has mixed feelings in his heart, is this a good change? Or is it a bad change?

"By the way, didn't you say there were three changes? What else is there? Zhang Nan asked.

"One more, and most important, is that the host can use the time travel function." System Channel.

"What, what! Time travel? Is that the plane travel I thought I was thinking about? Zhang Nan was shocked, this is the most shocking news he has heard since he came to Datang, does this mean that he can now live back and forth between Datang and modern times? In this way, he is a noble lord in the Tang Dynasty, and in modern times......

With so many cultural relics in the Tang Dynasty, how bad can modern life be? Even if Zhang Nan brought the toilet he used at night to the modern era, it would be regarded as a precious cultural relic of the Tang Dynasty, not to mention the precious paper cultural relics that he could easily get in the Tang Dynasty.

"It's a space-time travel that the host understands, but there are limits to this kind of travel, if the host wants to know, I can explain it to the host now." System Channel.

"Say it, say it." Zhang Nan can't wait now, Zhang Nan never thought that he would be able to return to modern times one day.

"The substitution of shuttle is very expensive, the host needs to consume a large number of points for time and space travel, and the time spent in modern times is very limited, if you want to stay longer, the host has only two ways to do it, one is to consume a larger number of points, because there are many ways to obtain points, so every time the host applies for an extension time, the points consumed will be doubled."
