Su Bai's face hurt even more, and the power of Ma Yan's kick is really not small! Covering half of his face, he said, "Let me ask you, why do people wear shoes when they walk?" "Don't you wear shoes to rub your feet?" , Cheng Chu answered without thinking about it, and then suddenly realized! Yes, people don't grind their feet when they wear shoes, so what about putting shoes on horses? Is it possible to solve the problem of horse hoof wear?

Su Bai saw that he understood and wanted to laugh twice, but the tears of pain were about to come down as soon as the corners of his mouth were pulled, so he could only say expressionlessly: "I nailed horseshoes to the horse's hooves, no matter how the horse runs, the horseshoes are worn out, and when the wear is serious, replace two horseshoes", Cheng Chumo's eyes are getting brighter and brighter, and his breathing is getting heavier and heavier, yes, this can solve the problem of horsehoe wear, and solve this problem, how many war horses can I save in Datang every year? 5,000 or 10,000? When the infantry is in difficulty, what if there are 5,000 more cavalry? The more he thought about it, the more excited he became, and his breathing became more rapid. Hurriedly ordered: "Quick, bring that horse back."

"Yes"

One of the tribes agreed, a few ran to the horses, just now the little horses were frightened and ran back to the stables on the side, the parts went over and grabbed the reins and pulled over, the little red horse was very resistant, it seems that just now it nailed the horseshoe, leaving a big shadow in its heart. Helplessly, the reins are in the hands of others, and no matter how reluctant they are, they have to pass, Cheng Chumo stared at the red horse and said: "Take it out for a few laps, come back and show me its horseshoe", the song agreed, led the horse to the side, it seems that it should be to experiment with the horseshoe.

Cheng Chumo said apologetically: "It's an ugly cow, why hasn't this gentleman come yet", but after Su Bai was kicked by the horse just now, someone went to call the doctor, Su Bai shook his head and said: "Don't worry, it's all painful now, and I don't feel anything", Cheng Chumo stared at Su Bai's face for a while, his face slowly reddened, and finally covered his stomach and laughed: "I'm sorry, I'm sorry, I know it's not appropriate to laugh at this time, but, I really can't help it, hahahaha", Su Bai's face was very dark, if it wasn't for his mansion, Su Bai really wanted to put this grandson to the ground with a fist!

Cheng Chumo led Su Bai to the hall, Su Bai came, and he didn't need Mrs. Cheng and other entertainment, Cheng Chumo had already given enough face when he came out! The two sat in the front hall, and the doctor walked in respectfully with a small medicine box on his back, and said to Cheng Chu silently: "Little grandfather", Cheng Chu waved his hand impatiently and said: "My brother let the horse's hooves kick his face, you can take a look."

The doctor gave Cheng Chu a silent look, took a few steps to Su Bai's approach, stared at Su Bai's swollen face for a while, and said softly: "Please bear with the son, I want to touch the child's face to confirm whether the bones are injured", Su Bai nodded and said: "Mr. trouble", the doctor smiled, reached out and gently touched Su Bai's right face, although it was already very light, he still gave Su Bai a painful straight air.

"Fortunately, Childe's skin injury is just a skin injury, the old man prescribes a plaster for pain and swelling for Childe, and it will be almost fine in three or five days", Su Bai hurriedly gave the doctor a salute and said: "Thank you, sir", the doctor smiled, left the front hall with a small medicine box on his back, it should be to dispense medicine, and when the doctor left, Cheng Chumo stared at Su Bai's right face..... The laughter of the little grandfather came from the front hall again....

......

"Little grandfather, my lord is back!" The two were sitting in the main hall chatting, the porter came to report, Cheng Chu smiled and said: "Go, I'll take you to meet my father", thinking of the celebrities who were about to meet the Tang Dynasty, Su Bai was still a little excited, the two of them just walked to the door of the main hall, and heard a heroic laugh outside: "Wowhaha, I heard that my son brought a friend today?" Let me see."

Su Bai looked in the direction of the sound, and saw a black-faced man walking forward, this big man was two meters tall, with a tiger's back and a bear's waist, and his beard was so thick that he couldn't see his mouth, walking dragon and tiger steps, followed by six full-body armor subordinates, his hand pressed the handle of the knife and was murderous, and at a glance he was a battle-hardened general! Cheng Yanjin was also startled when he saw Su Bai's current appearance.

Seeing that Su Bai is now wearing a scholarly white robe and a gray leather coat, it stands to reason that he can be regarded as suave, but what is the matter with the half of his face that is bulging like a pig's face? Could it be that this kind of dress has become popular in Chang'an recently? Hey, the old man seems to be outdated, not a trendsetter in the fashion industry!

Su Bai looked at Cheng Biting Jin, and hurriedly bowed and saluted: "Student Wang Chouniu, meet Lord Guogong!" Cheng Yanjin smiled and helped Su Bai and said: "Hahaha, the virtuous nephew is polite, since he is a friend of Chu Mo, don't call me any Guogong, just call me Uncle Cheng!" Su Bai, who was shameless, hurriedly climbed the pole, and changed his name to Uncle Cheng at that time.

Cheng Chumo watched the two say hello after they finished greeting, and quickly interjected: "Dad, we have found a way to prevent the horse's hooves from wearing!" Cheng bit Jin Tiger's eyes, and at that time, an inexplicable heavy aura enveloped Su Bai and the others, and Su Bai's body stiffened! This, is this the domineering spirit of the legendary superior? Cheng Yanjin's eyes became serious, and he stared at Cheng Chu and said silently: "Found a way to prevent the horse's hooves from wearing?" Cheng Chumo was a little scared when he saw Cheng Biting Jin's expression, this is the sequelae of letting his father beat!

"Uh, it should be, it should have been found, yes, Dad, this method was invented by the ugly cow brothers" Cheng Chumo stammered when he spoke, and when he saw Su Bai's eyes lit up, he quickly pushed Su Bai in front of Cheng Yanjin.

Cheng Biting Jin's eyes stood up, staring at Su Bai tightly and said, "Virtuous nephew!" Is what Chu Mo said true? Su Bai directly faced Cheng Yanjin's gaze this time, and felt a great pressure on him, as if as long as he said a lie, he would be torn to pieces by the person in front of him.

"Gollum"

Su Bai couldn't help but swallow a mouthful of saliva, it was originally a meritorious service, how could it be so scary? Forced himself to calm down, and just wanted to explain, a sound of horses' hooves came, and Cheng Biting Jin's ears moved, how is this sound of horses' hooves weird? I haven't figured out what's going on, I just went out to try the horse's part and came back, and I saw that everyone was hurrying to salute, and then said to Cheng Chumo with an excited face: "Little grandfather, this method is really useful, the horses are running unharmed, and when I came back, the villain checked it, and the horseshoes were all in good condition, which can really prevent the horse's hooves from wearing."

As soon as Cheng Biting Jin heard this, he reached out and grabbed the hooves of the little red horse, the resistance of the little red horse was simply vulnerable under the strange power of Cheng Biting Jin, Cheng Biting Jin took a look, and saw that the horse's paw was nailed with a crescent-shaped iron piece, Cheng Biting Jin had been fighting for so many years, and the war horse was a companion, and at a glance he could see what the use of this crescent-shaped iron piece was, and then he was stunned, followed by ecstasy, followed by sadness, and his facial expression was called a rich ah.

Seeing his father like this, Cheng Chumo didn't dare to disturb, just waited silently on the side, even he was like this, not to mention Su Bai and them, they didn't dare to breathe at all, so they heard Cheng bite Jin and murmured: "Just such two small pieces of iron, no one can think of them in the past thousand years!" If my Datang had this little piece of iron ten years in advance, where would there be the shame of Weishui! ”。

Cheng Yanjin turned his head, his eyes were red, and he didn't know what the past had come to mind, his face was hideous and terrifying, and Su Bai's little heart was pounding!

"Boy, this is what you came up with?" Cheng Yanjin asked, Su Bai was stunned, what do you mean? Is this old guy trying to swallow credit? When he was thinking about what to say, Cheng Chumo agreed for him first: "That's right, Dad, this is what my ugly cow brother invented!" ”。 Su Bai could only nod his head, and Cheng Yanjin also realized that he might be a little scared of this kid now, so he patted Su Bai on the shoulder and said with a smile: "The hero is a young man, the old man will go to your majesty to ask for credit" After speaking, he went out with six subordinates and a little red horse.

After seeing Cheng Yanjin walk away, Cheng Chumo exhaled deeply and said: "Okay, ugly cow, now you can be regarded as a meritorious service, hahaha, hey?" Ugly cow brother, it's obviously a happy event, why are you worried? ”

"Your dad has hit me twice, and I don't feel half of my body now! Did the doctor leave just now? I didn't leave and called back, I think I can still save it! ”......

......

His Majesty Li Shimin, our heavenly khan, is exactly thirty years old this year! It is the peak period of a man, on the first day of the new year, inviting all the ministers to the banquet, just a busy day, as an emperor who is eager to prove himself, he did not rest, but came to the study to review the folds, this winter has not snowed, His Majesty the emperor also understands what this represents, frowning, has planned to convene Fang Xuanling, Du Ruhui, Changsun Wuji and others in the next few days to discuss, everywhere needs to prepare relief food, how did you get the throne?

If it is really a catastrophic year, and there are two people with ulterior motives who raise their arms and shout, and their own throne is also unjustifiable, I am afraid that there will be wars and chaos for a while, and it will be restored to the scene of the eighteenth road anti-king split! Just when he was worried about these things, the door of the imperial study quietly opened, and a small yellow door walked in, and said softly: "Your Majesty, Lu Guogong asks to see!" ”。

"Oh?" Li Shimin was a little surprised, this old man had just left for less than an hour, why did he come back again? Isn't there something you've taken a fancy to me again? Two days ago, I just removed a pair of incense burners. At the mention of Cheng Biting Jin, Li Shimin's face couldn't help but leak a headache expression, this veteran who fought for him in the south and the north can be said to make him love and hate.

"Xuan" Li Shimin said weakly, the yellow door should be, and quietly withdrew from the imperial study, it didn't take long for Cheng Yanjin's deliberately low or loud voice to sound: "Your Majesty is in the imperial study" "Shhhhh My Lord Lu Guogong, you can be quiet, the saint is reviewing the folds, and the servants will give you a message! ”

"No need, bring him in!"
