Under Zhang Nan's continuous brainwashing of Empress Changsun every day, coupled with showing a large amount of evidence to Empress Changsun, from video files to patients' statements, Empress Changsun finally reluctantly agreed to the operation.

A week later, the degradable stent ordered from abroad finally returned.

The surgery was finally able to proceed normally.

Cardiac stents are divided into two ways, one is the radial artery and the other is the femoral artery, and the two surgeries have their own benefits, the advantage of the radial artery is that it is easy to stop bleeding, and the patient does not even need to stay in bed, and can move directly to the ground. The disadvantage is that the requirements for the doctor's surgical technique are relatively high.

The femoral artery is a little worse, not only is it more difficult to compress and stop bleeding, and the patient needs to lie flat for a period of time, but the patient is also prone to edema during the period of bed rest. Of course, it is not without benefits, and the advantage is that the requirements for doctors are relatively low.

These two methods Zhang Nan chose the first radial artery almost without thinking, after all, this is a big hospital, and the person who operated on Empress Changsun was a well-known medical professor in China and even in the world.

Originally, this professor didn't do such a simple operation, but he didn't know what relationship Su Qian used to bring such a well-known professor to operate on Empress Changsun.

Just after Empress Changsun was pushed into the operating room for surgery, Zhang Nan finally had time to rest for a while, these days can make him tired, not only to give Empress Changsun psychological counseling, but also to Li Lizhen and Empress Changsun to constantly explain the new things they encountered, and finally empty Zhang Nan sat on the chair outside the operating room scratching his head.

"Why do you always feel like you've been missing something lately? What did I forget again? Zhang Nan seemed to feel that he had forgotten something important, but Zhang Nan couldn't think of anything.

Datang, Chang'an City, Imperial Palace, Fengluan Hall Gate.

At this time, Comrade Li Er stared at the place where Empress Changsun and Zhang Nan left with big blood-red eyes, and he wanted to stare out his eyes, but unfortunately the place where the black hole appeared was still silent, and there was no reaction.

On a few occasions, Comrade Li Er even saw an illusion and saw Zhang Nan return with the eldest grandson Empress in good health, but unfortunately it was just an illusion.

"Your Majesty, please eat something." Liu Bing was holding a small bowl on the side and persuaded bitterly, not only Comrade Li Er was sitting on the chair and waiting, but even the eldest grandson Wuji and Li Chengqian were also staying in the Fengluan Hall of the eldest grandson queen.

Li Er waved his hand, signaling that he didn't need to eat.

"Your Majesty, it's been seven days, if Lord Zhang can come back, he must have come back a long time ago, besides, even if the queen mother is cured, then she has to recuperate and come back, right? You still have to eat two bites, you haven't eaten for a day, and if the queen comes back, what can you do if you fall ill again? Liu Bing was like Comrade Li Er's old mother at this time, and kept persuading Comrade Li Er to eat two bites of rice.

However, Comrade Li Er still didn't even open his mouth.

"Your Majesty, you should eat a little, Gonggong Liu is right, if the queen comes back, what should you do if you fall ill, you are anxious, and the minister knows, but you can't skip eating." The eldest grandson Wuji also opened his mouth to persuade.

Hearing the words of the eldest grandson Wuji, Comrade Li Er reluctantly said, "How can I eat it?" As soon as this Guanyin went, there was no news, and Qingquan's mobile phone couldn't get through. ”

"Father doesn't have to worry so much, with Master Zhang here, the queen mother will definitely have no problems, you can rest assured." Li Chengqian has surprising trust in Zhang Nan, in his opinion, there is nothing in this world that Zhang Nan does not know, and now Zhang Nan has taken Empress Changsun to the place where he grew up, it must be foolproof.

"Hey, having said that, I also know Qingquan's ability, but this is good to give people a letter, when Qingquan left, he said that there would be news in three days, but now it's been seven days, and Guanyin still has no news at all, which is really hard for me to sleep."

Just as Comrade Li Er was speaking, there was a sudden thunderclap in the sky, which startled Li Chengqian and the eldest grandson Wuji, but Comrade Li Er's face showed an excited look.

"It's back, it's back, when Qingquan left, there was a thunderstorm, and now it's a thunder on the ground, it must be Qingquan back, get out of the way, Qingquan said that when he came back, it was the position when he left, don't block the way back to Qingquan." Li Er said excitedly.

Before Comrade Li Er's words fell, the black hole that made Comrade Li Er love and hate appeared in the Fengluan Palace, and before a few people could react, Zhang Nan appeared in the Fengluan Palace.

Before Zhang Nan could stand firmly, Comrade Li Er rushed forward and grabbed Zhang Nan's neck, and then said, "Qingquan, how is Guanyin?" ”

Zhang Nan just wanted to answer, then glanced at Comrade Li Er's face, and then said: "Your Majesty, I haven't seen you like this for a few days." ”

"Eh, don't worry about me, what's going on with Guanyin now? Say it quickly, I'm dying. Comrade Li Er shook Zhang Nan's body and asked anxiously.

"Your Majesty, don't shake it yet, it's so shaking that the minister's head is dizzy." Zhang Nan said helplessly.

Hearing Zhang Nan say this, Li Er let go of Zhang Nan's neck, and then said, "Okay, okay, I won't shake you, you can say it quickly." ”

After Li Er let go of himself, Zhang Nan spoke: "If you go back to the emperor, the queen's illness has been cured, and she will be able to come back in a few days." ”

"Not a day? Why not? Didn't you really say that Guanyin's illness had been cured? Why don't you come back? Comrade Li Er asked strangely.

"This ...... The queen mother picked a lot of places during the treatment period, and said that she would go to these places to go around, so the queen mother said that she would play for a few more days and come back. Zhang Nan was also quite helpless.

“......”

"Is it really that fun over there?"

"I don't know if it's fun, anyway, the queen said when she finished transferring these places and when she would come back, and she also said that it was the doctor who asked her to go outside more and keep a good mood." Zhang Nan was powerless to refute the reason put forward by Empress Changsun, and the doctor's advice was really like this.

"Then you can bring me over too, Guanyin is alone over there, I don't feel at ease." After Li Er thought about it, he asked Zhang Nan to bring him to modern times as well.
