Seeing that the two of them really didn't know, Li Mu was slightly happy in his heart, it was originally a consumable for the level, but he didn't expect it to become a small invention. Li Mu cleared his throat, took out the posture of selling to Party B Company in his previous life, quickly formed a story in his mind, and said: "This is a small test for the kid, I don't know if it can work, and I hope the elders will correct it." When I was captured, I was feeding horses in a Turkic camp and mingling with them all day, and after a long time, I discovered something. ”

Cheng Biting Jin was anxious, and said, "Hurry up!" What's up? ”

"The law of the Turks killing horses." Li Mu said: "Although there are many horses in the Turkic camp, they don't often kill horses, and only when the horses' hooves are broken, they will kill the horses to eat!" ”

"Isn't that nonsense!"

"Don't worry, you're not done yet." Li Mu said: "I thought that the degree of wear and tear of the horse's hooves should be related to the age of the horse, the older the horse, the more serious the wear of the horse's hooves, but after actual observation, I found that this was not the case." At that time, the Turkic battalion gathered the remnants of the army, and there were tribes from wherever they came. I have observed that the hooves of the Gobi tribes wear out faster than the hooves of the steppe tribes! ”

"Another nonsense! Can stepping on a stone be the same as stepping on a turf? ”

Li Mu ignored it and continued: "At that time, I was thinking that the horse's hooves are the same, because they live in different environments, so the degree of wear is different. People also live in different environments, so why is there no such difference in the wear and tear of the feet? ”

Cheng Yanjin answered again and said, "Everyone wears shoes, you take off your shoes and try it!" ”

"Ahh Li Mu finally responded to him and said, "That's the truth, people can wear shoes, why can't horses?" If you put shoes on a horse, won't it be able to resist the wear and tear of its hooves just like a human? ”

Cheng Yanjin subconsciously opened his mouth and wanted to answer, but when he heard Li Mu say this, he suddenly didn't know how to answer. Yes, this is another nonsense, but the question is, how can no one think of such a simple truth?

Li Mu picked up a branch, squatted down on the ground and drew the shape of a horse's hooves, and said, "Everyone, please look at this picture, this is what the horse's hooves look like." Saying that, Li Mu pointed to the horse next to him again, and then he put the built horseshoe on top of the pattern: "The iron piece I hit can just cover the place where the horse's hooves are in contact with the ground, and at the same time it can put the horse's hooves together to prevent the horse's hooves from stepping on hard objects and cracking. ”

After speaking, Li Mu clapped his hands and got up, and said, "I think it can be useful, but I haven't experimented yet, and I don't know if it really has the expected effect." ”

This sentence is also a nonsense, it has been said so clearly, fools know that it must have an effect. Cheng Yanjin and Li Bi didn't speak, and the family members present didn't speak, they weren't shocked, but they were all thinking, why didn't they think of such a simple thing.

Cheng Yanjin took a deep breath, forced down the idea of doubting his IQ, and said, "Boy, this is the business you want to do with me?" This can't be done, although you have a clever mind, anyone can see it at a glance, and you can't make money. ”

Li Mu waved his hand and smiled: "How can you use this to make money, it's just a flash of inspiration, if it can be useful, it will definitely make everyone in the world know, if you can lose less horses because of this, wouldn't it be a blessing for the Tang Dynasty?" ”

"What a blessing for the Tang Dynasty!"

Suddenly, there was a cheer at the door of the martial arts arena, and everyone looked for prestige, it turned out that Li Shimin arrived, Gao Gonggong accompanied him, Li Ji followed him, everyone hurriedly saluted, Li Shimin waved his hand, and said: "It's not in the court, you don't have to be formal." I came here today because someone asked me to discuss a personal matter with Li Mu, so I came here on purpose. I didn't expect to hear such a conversation, and I was very relieved, Li Mu is young, intelligent, and can think about the country, which is very rare, very good, very good! ”

Li Mu hurriedly said: "Your Majesty praises falsely, and the ministers dare not be." It's just a few pieces of iron, it's nothing, and the minister just pays more attention to it. ”

"Aiqing doesn't have to be too humble." Li Shimin walked over, picked up a horseshoe, looked at it carefully and put it down, and said: "Although this thing is simple, but it goes back thousands of years, no one thought of it, but you thought of it, isn't this a skill?" And although this thing is small, it has a lot of use. Good horses are rare, there are often good horses because of the wear and tear of the horses' hooves, and have to abandon the things happening, with this thing, I don't know how many good horses can be saved, my Tang cavalry, will also benefit a lot from this thing. This is not a small achievement, and I should reward you. ”

"I don't dare to be rewarded by Your Majesty anymore, the minister is young, and he is lucky to be favored by His Majesty and the Emperor, and he has been awarded the title of county marquis, and his heart is very panicked. The minister knew in his heart that the slightest effort was not enough to support the position of marquis, so he only hoped that he could share his majesty's worries more and be more stable in his heart. It's just a few pieces of iron, if Your Majesty rewards it again, the minister should not know how to face the world. I beg your Majesty not to reward your ministers. ”

Saying this, Li Mu was shouting in his heart, Li Shimin, you are the first emperor of the ages, don't be influenced by my kid, you must stick to your own opinions, the more you don't let you reward, you have to be rewarded, you have to have this temper!

Li Shimin said with a smile: "There are many people who can't introspect, so they often feel sorry for themselves. At your age, I am glad to have such a understanding. Don't worry, I won't reward you with your title and wealth, but I will reward you with a chance to display your talents. In the past few days, Duke Mao has admonished you several times, saying that you are still young and cannot be crowned a high-ranking official because of your title, and I also think so in my heart, so I have not awarded you an official for a long time. Today, seeing your ingenuity, I suddenly feel that the Ministry of Industry is very suitable for you, so I will appoint you as the Langzhong of the Ministry of Industry, and I will take office tomorrow. ”

Li Mu was stunned when he heard it, he wanted to know what the Ministry of Industry did, and Lang Zhong was a few officials, but he couldn't ask on this occasion, so he had to hide his doubts in his heart and thank him.

At this time, Li Shimin saw Cheng Biting Jin and said with a smile: "Zhijie, you haven't been to the court for a few days, why, are you angry with me?" ”

Even if Cheng Yanjin was a scoundrel, he didn't dare to be presumptuous in front of Li Shimin, so he bowed down and said: "Your Majesty, I have occasionally felt cold in the past few days, but it is just a little better, and tomorrow the minister will go to court." ”

Li Shimin didn't poke it, nor did he ask why Cheng Yanjin appeared here, nodded with a smile, and said again: "I came here today to discuss with Li Mu for a private matter, Mao Gong, borrow your place for a purpose?" ”

Li Ji hurriedly said, "Your Majesty, please." ”

Li Mu looked at Li Ji for help, wanting to ask what kind of private matter it was, and he could work hard for Li Shimin. Li Ji shook his head, saying that he didn't know, Li Mu had no choice but to follow the two of them nervously and came to Li Ji's study.
