"Third brother, take care!" The younger sisters couldn't hold back, and tears fell, after all, the eldest of them was only 15 years old.

"Okay, don't cry, the third brother is gone, wait for the third brother to come back and bring you gifts." Li Ke smiled and waved his hand in a chic manner, I don't know why, but his mood suddenly became very good.

"The sea is smiling, the tide on both sides of the waves, the ups and downs are remembered with the waves."

Li Ke turned the horse's head and sang loudly, he didn't bother to care whether the song was in line with the environment of this era, as long as it was in line with himself, if it didn't conform to the times, then let the times conform to him.

……

While singing, Li Ke waved his hand to Changle and them, and then clamped his legs, and the war horse under his crotch instantly understood the meaning of the master, and directly raised his legs and galloped away.

Li Ke's novel singing voice still came from the horseback.

"The sky is smiling, the tide is in the world, who loses and who wins, God knows."

"The rivers and mountains are laughing, the smoke and rain are far away, and the waves are exhausted ......"

The singing was no longer audible with Li Ke's distance, but for some reason, Changle and the others suddenly felt less sad, perhaps from Li Ke's interesting singing, they heard a kind of ease.

"Did you write it down?" Changle turned around and asked.

"A few words, I'll compose music when I get back." Baling is better at this, and immediately spoke, as she spoke, she also hummed, "The sea is laughing, the tide on both sides of the strait is ......."

……

After returning to the queue, Li Ke and the others went straight to Chihai along the official road!

However, although the horses they went to the Western Regions this time were all the famous Qinghai Qiang, this kind of horse originated in Persia, and after coming to Qinghai, it was gradually improved, and it could travel thousands of miles a day. It is the best horse produced by Tuyuhun.

The largest number of Qinghai horses are in Tuyuhun, and there are a small number of them in Datang, which are all raised in the Qilian Mountains, and the Shandan military horse farm established by the Han hussar general Huo Quai, even after more than a thousand years, is the world's largest military horse farm!

Although these war horses can be claimed to travel thousands of miles a day, they can't really ride like this, and it will be useless to ride like this, Li Ke They galloped for a while, and then slowly moved forward, let the war horses rest, and then galloped wildly, and arrived at the post station at noon to rest, and the driving distance of a day was controlled at 300 miles.

The galloping speed of the war horse is about 60 kilometers per hour, so the cavalry is still very fast.

The endurance of the Qinghai horse is very strong, even stronger than the Mongolian horses of later generations, but unfortunately, it is not as good as the Mongolian horse in terms of rough breeding.

Genghis Khan's iron horse can sweep the world, the Mongolian horse can be said to be a great contribution, this speed and size are not outstanding, endurance can only be regarded as an excellent horse breed, with one of the biggest advantages to kill almost all other war horses, that is, rough breeding and endurance.

Mongolian horses can advance a distance of more than 300 miles a day, and the point is that it can continue this kind of high-intensity march for more than ten or twenty days in a row, not to mention, it only needs to be rough-fed, that is, it can be stocked directly on the grassland.

You must know that all war horses in ancient times needed to eat grain, and you can imagine how convenient this kind of rough feeding provided to the Mongolian cavalry.

In the evening, Li Ke and the others stopped at a post station, and all the cavalry quickly helped the post guards to park the war horses, and then added grain feed to the war horses, and each war horse hung a large salt block there to lick by themselves.

Good war horse breeding is necessary to eat salt, and it is naturally better to eat good salt, so if the Chaka Salt Lake is done well, it is also conducive to large-scale breeding of Qinghai war horses in Qinghai Lake and Shandan Military Horse Farm.

Li Ke easily turned over and dismounted, and the riding distance of 300 miles a day was not difficult for him.

But for Li Su...... It's torture, at this moment, Li Su was directly helped off the horse, it would be good if he could keep riding down, just because he was not wearing armor, but wearing a leather armor.

Li Su can also ride a horse, but he has never ridden a horse with such intensity.

Li Ke went over and looked, the place where the medical officer examined Li Yu was in the courtyard of the post station, and he didn't enter the room, and Li Ke specially ordered it, but he didn't let him come out to enjoy the blessings.

"Your Highness, the sides of His Royal Highness King Liang's thighs have been worn out." The medical officer in charge of examining Li Ke reported to Li Ke.

"Third brother ......" Li Su wanted to cry at the moment, he originally thought that going to the Western Regions was a very fun thing, but one day riding a horse, in addition to eating and resting, he was in a hurry, at first he could maintain a correct riding posture, but later, his physical strength could not keep up, he could only sit on horseback, he felt that the whole person was almost upside down.

And his legs were even more painful, even worse than kneeling all night that day, and now he felt that his legs were not his own.

"Can we have a day off tomorrow?" Li Su asked tentatively.

"No, you're just a small injury, use this to disinfect him, then apply medicine, and wrap him in boiling gauze." Li Ke took out the medical alcohol from the items he was carrying and handed it to the medical officer.

"Yes!" The medical officer took the alcohol with a calm face, and the medical officers in Li Ke's escort were all trained, and they already had a basic understanding of some modern medical knowledge, such as disinfection, such as how to prevent epidemics, some ways to prevent wound infection, and so on.

"Two of you." Li Ke greeted again, and two more guards soon came in outside.

"Hold him down." Li Ke pointed at Li Su.

Li Su's face was confused, he didn't know the seriousness of the matter, medical alcohol disinfection is like this kind of abrasion, but it is much more painful than hydrogen peroxide, and hydrogen peroxide will only be more painful than alcohol when the wound is very deep.

Although Li Ke carried hydrogen peroxide, it is better for children to suffer a little.

When the medical officer directly rubbed the medical alcohol cotton on Li Su's wound, he directly let out a miserable scream, "Ah...... It hurts me to death...... Ah, Your Highness is going to kill you. ”

The conscience of heaven and earth, Li Su didn't have this idea in his heart, he just said this sentence by reflex, usually he is used to scolding people like this, but he only scolds on his lips, and he has never really done it.

"Stop." Li Ke raised his eyebrows and spoke.

The medical officer and the two guards who held Li Su stopped, and Li Ke grabbed a handful of soil directly from the ground next to the post station, and threw it directly on his wound without waiting for Li Su to react.

"Ah......" Li Su screamed again, and the whole person trembled directly.

"Give him the alcohol." Li Ke shook his head and gestured, and the medical officer silently put the alcohol next to Li Su.

"You disinfect yourself, do you know? On the battlefield, seventy percent of the soldiers who died from injuries did not die directly, but died after the war because the wound was infected and could not be disinfected, and then the wound festered and pus. ”

"And wound infections are no matter how big or small, and a small injury like yours will still have a chance to be infected and festering and die, so I'm afraid that you will kill my medical officer, and the third brother can't afford to provoke you, so disinfect yourself." Li Ke said lightly.

Li Su: "......"

Of course, there is such a thing as wound infection, what Li Ke said is true, although it is not so mysterious, when Li Ke was six or seven years old in his last life, his knees did not get better, he ran and fell and rubbed it before he waited, and he had not disinfected it or anything, at most he washed it with water, and it soon scabbed, and the wound that Li Ke rubbed on horseback was at this level at best.
