However, the old man did not make Li Chengqian confused for a long time. A palace maid not far away waved. Xiao Li saw the palace maid coming with a familiar box.

"Father, where did you come from?" After the box was placed on the table, Li Chengqian asked in confusion with uncertainty.

"Of course I borrowed it from Doctor Sun." His Majesty Li Er opened the box in his son's incredible gaze and took out the stethoscope that Sun Simiao had not left for a moment: "But I heard him say that this thing seemed to flow out of his hands. Is this true?"

Really, of course, really, do you need to ask such a strange thing? Apart from Li Chengqian, there will be no one else to mess with Mandatang, even if Xiao Li wants to admit it, it will not work.

So Li Chengqian could only nod helplessly: "Father, this thing is called a stethoscope, which is an indispensable thing in medicine, but it does not have much use for other industries, so after the son is done..."

"Stop, I don't want to know how this thing came about, nor do I don't want to know the principle. As long as you bring me three more sets of things, I will give you the three positions you want immediately." His Majesty Li Er obviously didn't have the patience to listen to Li Chengqian's brag, and reached out to take out the stethoscope from the box and fiddled with it, and made a very unexpected request from someone.

Three stethoscopes were exchanged for three fifth-rank Yuanwailang? And what about this good thing? Li Chengqian couldn't believe his ears.

This is a fifth-rank official from the Tang Dynasty. In later generations, he was equivalent to a municipal cadre. He could actually get it with a stethoscope? It seems that this technology is indeed the primary productive force.

With a lot of funny feelings, Li Chengqian walked on the way to leave Tai Chi Palace and kept giggling until he saw Sun Simiao coming in from outside in a hurry.

"Hey, Lao Sun, why are you so free today to come to the palace to see me?" Li Chengqian stopped Sun Simiao and asked with a smile.

"Oh, Your Highness, the Crown Prince, who, can Your Majesty be in the palace?" Sun Simiao was also really a human being. He didn't know what lying was, and his purpose of entering the palace was revealed in one sentence.

"Uh..., now, it's in Ganlu Palace. That, it turns out that the Taoist priest went to the palace to look for his father!" Xiao Li scratched his head awkwardly and glared at Yang Yuxin who was still laughing.

This is also why Xiao Li felt that he had taken advantage of the old man and was a little too excited. He never thought that if Lao Sun wanted to find him, he should go to the Eastern Palace, not the Tai Chi Palace.

If this matter is placed on a relatively smooth person, it may be used in the East Palace that he did not find Li Chengqian, and then chased him to the Tai Chi Palace to make excuses. However, Lao Sun was not a smooth person and even turned him back in a daze.

Yang Yuxin admired Li Chengqian's embarrassing performance throughout the whole process. Seeing that his expression changed from pride to embarrassment, how could he still bear it?

Fortunately, Li Chengqian is a thick-skinned person and doesn't know how to hold grudges when he is criticized. After laughing awkwardly, he curiously grabbed Sun Simiao who was about to leave and asked, "Old Sun, what's the matter with you looking for my father in a hurry? Can you tell me?"

"Oh, there is nothing that cannot be said." Sun Simiao hesitated for a moment, and after Li Chengqian's questioning, he told the reason why he came to find Lao Li.

It turns out that Lao Sun was thinking about it a few days ago after he arrived at Qin Qiong's mansion. After seeing Lao Qin, he was taken to the palace and came to take the pulse of Empress Changsun at Lao Li's request.

This pulse is actually nothing. Queen Changsun has been pregnant for several months. Li Er can feel more at ease when asked to treat Lao Sun.

But Lao Sun, a honest man, forgot the truth that he would not reveal his money. Because he looked at his box too tightly, he was worried about Lao Li.

Needless to say, everyone can guess what happened next. His Majesty Li Er naturally needs to know what the stethoscope is for and where it comes from.

When he heard that this was something that Li Chengqian had created to listen to the heartbeat of the pregnant woman's fetus, Lao Li's curiosity became stronger and he forced himself to borrow the stethoscope from Lao Sun. Since then, the stethoscope entered the palace gate as deep as the sea, and it did not appear in front of Sun Simiao again.

And what about Sun Simiao? Lao Sun, who knew it was difficult to make this thing, was of course reluctant to give up the only stethoscope in the Tang Dynasty. Therefore, it became a routine to go to Tai Chi Palace every day, which made His Majesty Li Er avoid it.

It was also after hearing this that Li Chengqian understood why the old man asked him to use three stethoscopes to exchange for three fifth-rank positions.

After understanding all this, Li Chengqian pulled Sun Simiao out and said, "Okay, Lao Sun, don't go to my father for this matter. I'll arrange for more people to get you. What do you think?"

"Of course it's good. I thank Your Highness." Sun Simiao was not a fool. His Majesty Li Er didn't want to see him. He knew that it was just because the stethoscope was too precious to him, so he kept chasing him.

Now that Li Chengqian has promised to get him a few more, he naturally doesn’t have to bother him anymore.

The brilliant Taiji Palace was the highest power organ in the Tang Dynasty, and the great His Majesty Li Er was the highest power person in this power organ.

But when the highest power of the Tang Dynasty brought the stethoscope and put his head on his wife's smooth belly with a strange smile on his face, it was so weird no matter how he looked.

"Second brother, you have been listening for a long time, why don't you be like this today?" Empress Changsun blushed and put her hand on Li Er's shoulder and whispered.

"If you listen for a while, you still hear that the guy did something good. This stethoscope is indeed extraordinary. It can really make me hear my child's heartbeat." Li Er first gave his wife a ban gesture, and then continued to listen for a long time until his ear was hurt by the small iron tube. He gave up listening to the fetal heartbeat.

"Qian'er is probably having a deep misunderstanding about her second brother during this period, right? I haven't seen him for a long time." When Old Li mentioned Li Chengqian, Empress Changsun's tone had an indescribable tone.

"Guanyin maid, you overestimate that boy. He is the one who is shameless and innocent." His Majesty Li Er snorted and continued, "I don't understand. How could he be so persistent? He has been honest for a few days, and his old illness has relapsed."

"Second brother, why don't you go with him. I don't think Qian'er is a child of misbehavior. Although she often causes trouble, she is still considering it for the Tang Dynasty." Empress Changsun knew very well which one would suffer if the old man fought with his son. If these two people really made a real fire, it would be a disaster for the Tang Dynasty.
