As soon as Li Shimin arrived at the door of the Lizheng Palace, he heard the coughing sound of Empress Changsun, and a trace of worry appeared on his face.

The weather is getting warmer, everything is recovering, but the eldest grandson's qi disease is becoming more and more serious, the imperial doctor in the palace is completely helpless, and even Sun Simiao's prescription is gradually invalidating, Li Shimin, who was already upset by Gaochang's affairs, felt even more anxious at this time, in his heart, only the eldest grandson is his real wife and not just the queen concubine, when he was still the king of Qin, the eldest grandson went through ups and downs with him, and the feelings in it are not comparable to other concubines.

Holding the hand of Empress Changsun, Li Shimin couldn't help but think of the days when he was still the King of Qin, and couldn't help but sigh softly.

"Why is Erlang sighing?" Although disturbed by the qi disease, Empress Changsun was still gentle and quiet as always.

"Time flies."

Hearing Li Shimin's emotion, Empress Changsun smiled: "Yes, in a blink of an eye, even the young slaves have grown up, and they are not around me all day long like before, but now only the son is still by my side." ”

Princess Jinyang, who was being fed and drinking porridge by the palace maid, heard the eldest grandson queen mention that she turned around and smiled sweetly, the four-year-old she was much more well-behaved than ordinary children, and she was kind and never cried, perhaps this also followed the temperament of the eldest grandson.

"Don't you like them pestering you very much, and you often say that you don't want them to grow up and leave." Li Shimin finally had a smile, the eldest grandson queen was generous, gentle and patient, and the little prince and princess in the palace liked to pester her on weekdays.

Empress Eldest Sun waved her hand at Princess Jinyang and sighed, "Now I hope that my son can grow up quickly." ”

Li Shimin heard the meaning of Empress Changsun's words, and his eyes turned red, an iron-blooded leader who did not change his face in the face of hundreds of thousands of troops, and a cold-blooded emperor who was unmoved by the blood that flowed like a river in Xuanwu Gate, but at this time, his eyes were red because of a woman.

Empress Changsun gently stroked Li Shimin's sideburns, and there were already a few silver threads mixed with it.

"It's all the emperors of the Tang Dynasty, why are they so easy to be red-eyed."

When Li Shimin was still the king of Qin, every time he encountered something unpleasant, the eldest grandson caressed his sideburns like this, he could always calm down, but this time it didn't work, Li Shimin held the hand of the eldest grandson queen tightly and trembled: "I'll ask Li Daochang to change the prescription when I go back, there is always a way for your illness." ”

"Hmm." Empress Eldest Sun knew about her condition, but she still nodded and smiled meekly.

If you really can't do it......

Li Shimin's eyes were fixed and he remembered the scene where Wang Xiang gave Cheng Chuliang a blood transfusion to extend his life, and the set of blood transfusion tools is still hidden in the inner library.

After Cheng Yanjin returned home, he came to the stable in the backyard, and the always brave and handsome Jinghong was covered in injuries and knelt in the hay with four hooves, and when he saw Cheng Yanjin coming, he struggled to get up, and his bloody front hooves trembled and trembled for a moment, and finally let out a sad cry and fell to the ground unwillingly, and a pair of copper bell-sized eyes oozed two cloudy tears.

"I don't blame you, old man."

Jinghong seemed to understand Cheng Yanjin's words, buried his head and let out a low whimper, and when he raised his head again, his radiant eyes had lost their luster, and Cheng Yanjin's heart hurt.

Once galloping the frontier invincible, now even walking has become a luxury, this is a more uncomfortable result than death for the proud Jinghong, it would rather die in battle than be a waste horse that can't even walk, it is begging Cheng Biting Jin to give himself a ride, how can Cheng Biting Jin not understand its eyes, just tell him how to do it. "You're recuperating." After speaking, he turned around and left despite the wailing of the frightened Hong.

Shocking and fierce, he slammed straight into the wall, and Cheng Yanjin was suddenly startled and hurriedly rushed forward to hug the horse's neck.

"Uncle Cheng's subordinates are merciful!"

Wang Xiang trotted all the way to the Lu Guogong Mansion, but he didn't expect to see Cheng Yanjin rolling on the ground with Jing Hong's neck as soon as he found the stable.

"Uncle Cheng, it's not surprising that Chu Liang said that this matter is not to blame, don't kill it."

Although Jing Hong was injured, his strength was still very strong, Cheng Biting Jin held the horse's neck when his arm was on the wall, Rao was his rough skin and thick flesh and grinning in pain, Jing Hong saw that Cheng Biting Jin was injured and then stopped and didn't dare to move.

"Who said I was going to kill Thriller?"

"And what are you?"

Cheng Yanjin moved his somewhat numb arm and said: "Jing Hong can't walk because of the wear of his front hooves, and he can't think about it for a while, and he wants to die, I just stopped it." ”

Wang Xiang looked at the front hooves of the bloody and blurred shock, a trace of surprise flashed in his eyes, Cheng Chuliang really guessed right, he didn't expect that there was really such a strong horse in the world!

"What are you doing here, is there something wrong with Liang?"

Seeing that Cheng Biting Jin's face was worried, Wang Xiang hurriedly said: "Brother Liang's body is no longer in serious trouble, Princess Qinghe is talking to him." ”

"And you're coming?"

Wang Xiang smiled bitterly and said, "Brother Chu Liang just learned that Jinghong also escaped Gaochang Jingqi, and was worried about its safety, so I asked me to come over and have a look." ”

Cheng Yanjin sighed and said: "Jinghong has a strong personality, I stopped it today and I am only afraid that it will ...... in the future."

"If it could run again, it wouldn't have died."

"What did you say?"

"I said that if Jinghong could run again, he wouldn't be looking for death, right?"

"Its front hooves can't touch the ground anymore, let alone run, and it's impossible to walk." Cheng Yanjin's mood was a little low, and Jinghong also whimpered in a low voice.

Wang Xiang scratched his head and said, "I have a way, maybe I can get Jinghong back on his feet." ”

Cheng Yanjin's eyes lit up when he heard this, and the first thing that came to mind was Wang Xiang's method of blood transfusion to save people, and he said excitedly: "Do you want human blood or horse blood?" ”

Wang Xiang suddenly broke out in a cold sweat, Nima, Lao Cheng is really more ruthless than Li Er, and directly asked if he wanted human blood or horse blood, I am afraid that he would not hesitate to get it no matter whether he asked for human blood or horse blood, but is it really a universal blood transfusion? The relationship between the wear and tear of the horse's hooves and the hair of the blood transfusion!

"Well, Uncle Cheng, there is no need for blood transfusion if this horse's hooves are worn, just get a pair of horseshoes."

"What is a horseshoe?"

Wang Xiang patiently explained: "The reason why the horse's hooves are easy to wear is because of the lack of protection, we know to wear shoes in order to protect our feet from injury, so why don't we put shoes on the horse's hooves when they are easily injured, and the horseshoes are the shoes of the horse." ”

"Shoe the horses?" Cheng Yanjin seemed to understand something, and asked again: "What shoes can withstand such wear and tear?" ”

"Iron, that's why it's called a horseshoe."

After coming to Datang, Wang Xiang understood a truth, the ancients had limited comprehension ability, and when you couldn't explain it clearly to them, it was easier to speak directly with facts.

"Uncle Cheng's mansion has paper and pencils, I draw the shape of the horseshoe, you ask the blacksmith in the mansion to build it according to the drawings I draw, and you will know when the time comes."

Hearing that he could make his beloved horse stand up again, Cheng Yanjin didn't dare to slack off, and hurriedly called someone to get a pen and paper, Wang Xiang first stepped forward to observe the horse's hooves, and then drew four horseshoes on the paper and handed them to Cheng Yanjin, Cheng Yanjin immediately asked the blacksmith in the house to build according to the drawings.

The blacksmiths of the Guogong Mansion are really powerful, and in less than a stick of incense, four horseshoes are made, and the shape and size are not bad at all.

"These are the shoes for horses?" No matter how Cheng Yanjin looks, he feels that the horseshoe in Wang Xiang's hand does not look like shoes.

If Wang Xiang knew what Cheng Yanjin was thinking, he would definitely despise him, could a horse's hooves be the same as a man's feet.

"Does it really work?"

"Just give it a try and you'll know."

Seeing Wang Xiang walking towards him with a few strange things, Jinghong instinctively resisted, and only relaxed under Cheng Yanjin's comfort, because Jinghong's front hooves have been worn, so Wang Xiang made some changes to two of the horseshoes, and bypassed the worn parts when nailing the horsesshoes, so that the worn parts do not need to touch the horseshoe, and naturally there will be no pain, and after a while, there will be no problem when the worn wound recovers.

Feeling that there was something more on the horse's hooves, Jinghong was still a little uncomfortable, and shook his hooves to get rid of things, but the horseshoe was nailed to the horse's hooves, how could it be so easy to get rid of it, in Cheng Yanjin's surprised gaze, Jinghong stood up and kept shaking the horse's hooves, and jumped twice from time to time, maybe it didn't realize that it was standing up again. When Jinghong found out that it was unusual, he was stunned for a moment, and then cautiously stretched out a horse's hoof and touched the ground, and then ran wildly in the courtyard with a cheerful neigh.

Cheng bit Jin Lao's tears, and said in his mouth: "Good, good!" ”

Wang Xiang also stood aside and looked at Sa Huan's shocking smirk, and the figure that was faster than lightning suddenly pounced on him, and then a wet tongue licked wildly on his face.

Cheng Yanjin is an experienced veteran after all, and after the surprise, he quickly discovered the importance of the horseshoe, so the subordinates who had been in contact with the drawings in the house and the blacksmith who made the horseshoe were directly controlled by Cheng Yanjin's personal soldiers, and Lao Cheng pulled Wang Xiang into the palace to see Li Er.

Li Er was thinking about whether to get Wang Xiang into the palace to help Empress Changsun have a blood transfusion to continue her life, but he didn't expect Cheng Yanjin to drag Wang Xiang directly into the palace.

As soon as I arrived at the Taiji Palace, I heard Cheng Biting Jin shouting without a head: "Your Majesty, the expedition to Gaochang is just around the corner!" ”

"Didn't the pharmacist say that now is not the best time to conquer Gaochang?" Li Shimin rubbed his temples with a helpless expression.

"Your Majesty is worried about the wear and tear of the horse's hooves?" Cheng Yanjin actually sold Guan Zi proudly.

Li Er knew Cheng Biting Jin too well, but he didn't speak when he looked at him, and the goods really couldn't help but speak by himself: "The prince has a new thing to solve the worry of the horse's hooves." ”

Li Shimin glanced at Wang Xiang with some surprise when he heard this, the wear and tear of horses' hooves has been an unavoidable problem since ancient times, and for this reason, a lot of war horses are lost every year, is there really a way to solve this problem?

Cheng Biting the golden fart presented the drawings to show off: "This thing is called a horseshoe, nailed to the horse's hooves is like putting shoes on the horse, which can solve the problem of horsehoe wear." ”

"Does it really work?" Li Shimin found it hard to believe that a few simple things on the drawings could solve the problem of horse hoof wear.

"My worn-out front hooves are a blur of flesh and blood, and it's hard to stand up, but with the horseshoe nailed to it, I can run as much as I want."

"Oh?" Cheng Biting Jin would never talk nonsense about this kind of thing, Li Shimin's eyes lit up, and he looked at Wang Xiang with interest and said with a smile: "This thing can't be obtained from the merchants of the Western Regions again, right?" ”
