Gao Ming thought about it for a while, and finally decided not to tell Li Su the truth.

After all, although Li Su is a little better, he can't always scold, and it is still necessary to establish a little self-confidence for him.

Therefore, at this time, Gao Ming smiled and patted him on the shoulder.

"The old man didn't scold you, what he meant was that your character is as fierce as a beast, your will is as hard as iron, as long as you work hard in the future, you can still become a talent, this is a good word, he is praising you."

Li Su didn't know that Gao Ming's was a "white lie", and thought that Li Shimin was really praising him, and he suddenly became happy again.

"Really? I didn't expect my father to praise me, it's so good, hehe! ”

Seeing his happy face, Gao Ming also laughed.

"Sixth, as long as you listen to the eldest brother, the old man may be proud of you in the future!"

When Li Su heard Gao Ming's words, his eyes suddenly brightened.

"Really?"

"Of course!"

"Hey, hey, hey, hey......"

Li Su seemed to have seen Li Shimin's pride in him, and immediately couldn't help laughing, looking at Li Su with a smirk on his face, although Gao Ming had a smile on his face, he secretly sighed in his heart.

"Alas, I really didn't expect that this guy Li Su was so eager to be recognized by Li Shimin!"

At this moment, the voice of the waiter suddenly came from outside the door.

"Your Highness, the Imperial Doctor has arrived!"

Hearing that the imperial doctor had arrived, Gao Ming immediately went and opened the door of the study.

"Let him come!"

"Yes!"

Soon, the imperial doctor followed the waiter into the study, and when he saw the blood stains on Li Su's face, he immediately took out a strip of cloth and prepared to bandage Li Su, but was stopped by Gao Ming.

"Uh...... Imperial Doctor, aren't you going to disinfect him first? ”

Hearing Gao Ming's words, the imperial doctor suddenly showed a puzzled face.

"Sanitization? Could it be that King Liang was still poisoned? ”

“……”

Gao Ming understood now, it turned out that the Tang Dynasty did not have the concept of disinfection, so he hurriedly explained it to the imperial doctor.

"Disinfection means to destroy the invisible bacteria on the patient's body, and if the wound is not disinfected, the wound may become infected, which can endanger the life of the injured person."

Speaking of this, Gao Ming suddenly found that both the imperial doctor and Li Su himself were confused with a capital letter, and he immediately sighed.

"Alas, forget it, this thing will not be clear for a while, Shishu, you can go and help me get some boiling water and salt now."

"Yes!"

The food bureau always has boiling water, so it only took a cup of tea for the waiter to bring back the boiling water and salt.

Under the curious gaze of the imperial doctor and Li Su, Gao Ming poured a small half basin of boiling water, and then sprinkled a handful of salt down, and after the salt was fully dissolved, Gao Ming threw the strip of cloth that the imperial doctor had just prepared to bandage Li Su into the basin, and then beckoned to Li Su.

"Sixth, come here, I'll help you wash your wounds!"

"Oh!"

Hearing Gao Ming call him, Li Su agreed and walked over obediently, and then Gao Ming endured the scalding and picked up the cloth strip in the basin, and used it to click the wound on Li Su's head.

When the cloth dipped in salt water touched the wound on Li Su's head, he suddenly screamed and jumped up.

"Whew...... Hiss...... Pain hurts pain ......"

Seeing him jump up, Gao Ming put his arms around his neck without saying a word, and then in his screams, he clicked the strip of cloth dipped in salt water on his head a few more times, and then let go of his hand.

The moment Gao Ming let go, Li Su immediately ran to the other end of the room screaming, and then looked at Gao Ming with a frightened face.

Gao Ming didn't look at him, but just threw the strip of cloth in his hand back into the basin and rubbed it twice, then picked it up and wrung it out and handed it to the waiter.

"Waiter, take this strip of cloth outside to dry, I'll use it later."

"Yes!"

The waiter agreed, took the cloth and went out, and then Gao Ming set his eyes on the imperial doctor again.

"Salt water can dehydrate bacteria, this is the easiest way to disinfect, the only drawback is that the concentration of this salt is a bit difficult to grasp, less salt has no effect, but if you put too much salt, the patient will have severe pain, just like Liang Wang just now!"

When the imperial doctor heard this, he immediately nodded.

"I understand, when His Royal Highness the Crown Prince said about the infection, it should mean that the wind evil has entered the body, right?"

"Wind evil into the body?"

Gao Ming was slightly stunned, and then immediately nodded.

"Yes, that's what it means, and disinfection is to prevent wind evil from entering the body."

"It turns out that just salt water can prevent wind evil from entering the body, and the lower officials have been taught."

Speaking of this, the imperial doctor immediately bowed to Gao Ming, and then looked at Gao Ming with a solemn face.

"His Royal Highness the Prince, the lower official has a plead, please allow the lower official to use this recipe of His Royal Highness in the Shang Pharmacy!"

Seeing the solemn look on the imperial doctor's face, Gao Ming immediately laughed.

"That's it? What else should I do, it's nothing, just use it if you want to, it's best to promote it to the people, presumably it can save some people. ”

As soon as Gao Ming's words fell, the imperial doctor's face changed again, he first glanced at Gao Ming deeply, and then bowed deeply to him.

"His Royal Highness the Crown Prince is noble!"

And at this time, Li Su suddenly ran over again.

"Big brother, this recipe is yours, how can you give it to others casually? You should dedicate it to your father, and maybe your father will be happy......"

Before he could finish his words, Gao Ming hit him on the head with a popping chestnut.

"He's not very happy either, since it's something that saves people, then you have to teach it to those who can save people, this is what you can do, and if you want to please the old man, I have more methods, I can make him laugh if I say a word, and I can make him jump when I say a word, believe it or not?"

"Uh......"

Hearing Gao Ming's "rebellious" words, Li Su was once again shocked and speechless, and the imperial doctor standing on the side couldn't help but twitch the corners of his mouth.

At this time, Gao Ming also noticed the imperial doctor's bewildered look, and after thinking about the key, Gao Ming suddenly smiled slightly, and then waved his hand at him.

"Okay, there's nothing for you here, you go back, remember to pass on this disinfection method as soon as possible, and you can save a person a day earlier."

Looking at Gao Ming's gentle smile, the imperial doctor immediately nodded solemnly.

"Yes, His Royal Highness the Prince, please rest assured, the lower official will go to do it immediately after he goes back, and the lower official will retire!"

After speaking, he saluted Gao Ming again, and then left Gao Ming's study.

After the imperial doctor left, Gao Ming chatted with Li Su for a while, and only when the sword came to tell Gao Ming that lunch was ready, he patted Li Su on the shoulder.

"Let's go, let's eat, you still have to run errands after eating!"

"Oh!"

Li Su agreed, and followed Gao Ming out of the study.
