The horseshoe was so easy to make that it was all made in a few days.

Li Jing asked Li Zhi to guide him on how to install the horseshoe.

What people didn't expect was that the installation of the horseshoe was very simple.

Just adjust the curvature of the horseshoe slightly to the shape of the horse's hoove, and you can nail it to the horse's shoe with an iron nail.

There is no need to arrange a special person for such work, only the fighters themselves can easily operate it.

So soon all the uninjured horses in the army were installed with horseshoes.

Those injured horses only need to regrow their cuticles after a while to be installed.

In fact, the part where the horseshoe is installed is the cuticle that resembles a fingernail.

At the time of installation, the war horse will not feel pain at all.

With the protection of the horseshoe, the soles of the horses no longer have to worry about wear and tear.

Even after a long time, you have to repair the soles of the horses to avoid the nails from growing too long.

After a few days of observation, Li Jing finally determined that this method was effective, so he immediately reported this method to Li Shimin.

After listening to Li Jing's report, Li Shimin asked in surprise: "Can you still operate like this?" Can you really save war horses? ”

Li Jing said: "The old minister has carefully observed, and this method is indeed miraculous. ”

Li Shimin laughed and said, "Okay! Good! Since this law is effective, the whole army should be immediately notified to change their uniforms en masse. ”

After saying this, he praised Li Jing again: "Aiqing is not only busy with government affairs but also managing the new army, and can come up with such a good strategy, he is worthy of being my humerus minister!" ”

Li Jing said with a little shame: "Your Majesty misunderstood, this law was proposed by His Royal Highness the King of Jin, and the old minister did not contribute. ”

Li Shimin asked with an "oh" sound: "It's a pheasant slave again?" He didn't have much contact with the war horse, how could he come up with such a good plan? ”

Li Jing said: "Your Majesty, His Royal Highness the King of Jin thinks that war horses should wear shoes like humans to run. ”

Li Shimin was slightly stunned after hearing this, and then quickly thought of the principle.

So he smiled "haha" and said: "I see, it's a pity that no one thought of this when I waited with the war horse all day." ”

Li Jing hugged his fists and said: "The old minister is ashamed. ”

Li Shimin waved his hand and said: "Aiqing, don't say that, I think we are all making the mistake of being a fan of the authorities." ”

Li Jing said: "His Royal Highness the King of Jin is indeed clear in his thinking, and the old minister is ashamed of himself. ”

Just as Li Shimin wanted to ask some more about the Dragoon, there was a sudden commotion outside the Taiji Palace.

Li Shimin's brows furrowed, and just as he was about to reprimand, he saw that Zhang Ananda, who was guarding the door, had already gone out to check first.

After leaning slightly, Ananda Zhang walked in with a little panic and said, "Your Majesty, His Royal Highness the Acting King is critically ill, and the Imperial Doctor is restrained. ”

Li Shimin's face changed when he heard this, and he hurriedly got up and walked outside the Taiji Hall.

As he walked, he said anxiously, "Go and ask Doctor Sun to come and have a look." ”

Zhang Ananda hurriedly took the order and left, and Li Shimin walked quickly to the harem.

In a side room in the Rouyi Palace, a little boy about two years old was lying quietly on the bed at this time.

The boy's face was somewhat sickly ruddy, and his breathing was slightly rapid, often accompanied by a rapid cough.

If you listen closely, you can hear a ralle sound from his breathing.

This boy is none other than Li Jian, who has just been crowned acting king.

Next to his bed, a plainly dressed beauty was sobbing quietly, it was the boy's mother, Concubine Lin.

There was also a royal physician and two palace maids in the room.

At this time, the imperial doctor was frowning, trying to think about what medicine could be used to delay the boy's condition.

The two palace maids stood a little nervously to the side.

At this moment, Li Shimin came to the room with the eldest grandson queen who came in a hurry.

Empress Eldest Sun walked quickly to Concubine Lin's side and whispered comfort.

Li Shimin opened his mouth and asked the imperial doctor, "How is the condition of the acting king?" Is there a cure? ”

The imperial doctor knelt down with a frightened face and said, "Your Majesty forgives the sin, the subordinate officials are incompetent, and they have not yet come up with a good plan." ”

After hearing this, Li Shimin frowned and waved his hand to signal him to stand aside, and then walked quickly to Li Jian's bedside.

At this time, Li Jian had fallen into a state of sleep, and his whole face was painful and a little cold.

Concubine Lin saw Li Shimin getting too close, and hurriedly cried and said, "Please take care of your majesty's body and don't get any closer, Jian'er's illness is very contagious." ”

Li Shimin waved his hand and said, "It's okay, Concubine Ai is relieved for the time being, I have sent someone to invite Doctor Sun." ”

Concubine Lin opened her mouth and said, "Concubine Xie Your Majesty." ”

Li Shimin stretched out his hand to test Li Jian's forehead and asked, "How many days has Jian'er been sick?" How could you be so sick? ”

Concubine Lin said: "It has only been two days since the sudden onset of illness the day before yesterday, and it is unexpected, and the concubine is not expected to be in this emergency. ”

Empress Eldest Sun said, "Have you taken medicine in the past two days?" ”

Concubine Lin sobbed and said, "The imperial doctor prescribed a prescription but it didn't work. ”

As the three of them were talking, Ananda took Sun Simiao and walked in quickly.

As soon as Zhang Ananda was about to inform Li Shimin, he preemptively said to Sun Simiao: "I also asked Dr. Sun to diagnose the child." ”

Sun Simiao agreed and walked quickly to the bed.

I saw that he first stretched out his hand to check Li Jian's pulse, and then carefully observed Li Jian's tongue coating and eyelids.

Then he said to Li Shimin with a little frown: "His Royal Highness the Acting King is a lung disease caused by a cold disease, and it is already quite serious at this time. ”

Li Shimin asked anxiously: "Does the divine doctor have a good prescription?" ”

Sun Simiao said: "If it was difficult to be sure of the lower officials before, fortunately, His Royal Highness the King of Jin has made a breakthrough in medical skills. ”

Li Shimin asked in surprise: "How can a pheasant slave have such a ability?" ”

Sun Simiao said: "His Royal Highness the King of Jin developed a microscope, which gave the old ministers and everyone in the medical school the opportunity to observe the germs, and boldly proposed the method of analysis so that the ministers and others had a deeper understanding of herbal medicine. ”

After listening to Sun Simiao's words, Li Shimin asked tentatively: "What the divine doctor said is related to chemistry?" ”

Sun Simiao nodded and said, "Exactly, the combination of this method and physics has benefited the ministers and others a lot. ”

Li Shimin happily said several "good" words in a row, and then he came to his senses and hurriedly said: "Please also ask the divine doctor to use medicine quickly, so that my child will suffer less pain." ”

Sun Simiao hurriedly prescribed the medicine and prepared to let the palace maid on the side go to grab the medicine.

At this moment, the imperial doctor who had been standing aside suddenly spoke: "Divine Doctor Sun, I don't know if I can let the lower officials take a look at the prescription, so that I can learn a thing or two." ”

He was very curious about the prescription written by Sun Simiao at the moment, because the cause Sun Simiao diagnosed was the same as his.

However, the condition that was obviously ineffective in his hands did not seem to be too tricky in Sun Simiao's opinion.

This made him a little puzzled.

It is important to know that this condition has been widespread before, and almost all doctors have mastered a set of general methods.

And at this time, Sun Simiao can still prescribe medicine when this method is invalid, how can this not make him curious?
