"Look at the Second Prince!"

Soon, the second brother's horse also checked, which was similar to Yu Zhigan, except that two of the second brother's horses were running halfway through, and the horseshoe fell. The second brother looked at it in a daze and muttered: "Impossible, Impossible!"

He couldn't figure out why the difference between the big brother and the horseshoe he used was so big? Is there anything he didn't learn?

"What do you think, dear generals?"

"Your Majesty, the horseshoe invented by His Royal Highness the Crown Prince is of great use. If all war horses are installed, the damage to our war horses on the battlefield will be greatly reduced, which will save a lot of expenses!"

“That is, it’s useful!”

"Reporting to Your Majesty, it's useful, not only war horses, but also ordinary slow horses can be used. Moreover, the horse equipped with this iron was obviously faster than the ones that were not installed!"

"Then why did the Second Prince's war horse have problems!"

After saying that, the emperor looked at Yu Tai. Yu Tai's forehead was sweating. He didn't know how to answer. After the emperor snorted coldly, he looked at Yu Zhigan again: "Crown Prince, do you know?"

Yu Zhigan observed the way the second son's horse nail was punched in, and smiled: "Father, my son's horse iron was burned under the horse's hooves after burning the horse iron red, while the second brother directly punched in with nails, which was not firm, so it fell off!"

"So that's it. Your Highness the Crown Prince is so smart. This invention of Ma Tie can be regarded as a benefit to the country and the people, but!"

"But what? Just say it!"

Zhao Kuangyin looked at the Ma Tie Road: "This mere four pieces of horse iron may require two kilograms of pig iron. I am accused of iron shortage..."

"I'm in the face of iron deficiency?"

Yu Zhigan was stunned for a moment. It was the first time I heard that China was short of iron. Yu Zhigan remembered that there were a lot of iron ore in China, such as Panzhihua Iron Mine, Ma'anshan and Liaoning.

It’s not that Yu Zhigan suddenly realized that he remembered so many things, but that he had been to these places, with mines everywhere in Panzhihua, let alone Ma'anshan. Almost everyone knows that the area of ​​Liaoning is almost the same.

"Your Highness, I don't know that all dynasties have been short of iron, and there is too little iron ore!"

Yu Zhi thought for a while: "Is there a shortage of iron? I remember a lot. There is a city next to Jinling called Ma'anshan, and there is an iron ore!"

“(#?Д?) I wonder where Ma'anshan that Your Highness said is located?”
