Guo Rong wanted to talk to Guo Zongxun about something else first, and then lead the topic to today's matter, but he didn't want Guo Zongxun to look excited when he came up.

Moreover, he also winked mischievously at Guo Rong, which means, father, you praise me.

"Oh, my father was a little tired of dealing with government affairs, and I want to talk to Xun'er to relieve my boredom, just right, tell me quickly, what did Xun'er do today, and what is the gift for my father?"

Guo Zongxun squeezed into Guo Rong's arms and began to ask for credit.

"Father, my sons have been thinking about my father's personal expedition these days, thinking that I can help my father do something, but I haven't had a clue, and today I can be regarded as having an idea."

After speaking, Guo Zongxun took out a piece of paper from his cuff and handed it to Guo Rong like a treasure.

"What is this, is it a painting drawn by Xun'er, this ...... Do you want your father to compliment you on how well you draw? ”

There were two very strange patterns drawn on the paper, Guo Rong didn't understand it for a while, looking at his son's excited face, and it was not good to discourage his enthusiasm.

"Father, the horse you gave to your son is covered with snow, and your son likes it very much, so he often goes to the imperial horse to watch it, and I heard from the little official who is in charge of raising horses that this horse's hooves are the easiest place to wear."

Guo Rong nodded, this is also the reason why there are not many cavalry in the Great Zhou Dynasty now, a cavalry often needs to carry two war horses, the main reason is that the hooves of the horses are easy to wear.

You can't fight a battle, and when you come back, you will run away with a horse, and in this case, the consumption of war horses will be too great.

"Father, the son painted this, you can nail a thick piece of iron to the horse's hooves, so that it is not easy to wear."

Guo Rong's eyes widened suddenly, and he even stood up, almost throwing out Guo Zongxun who was sitting in his arms.

"Xun'er, make it clear, what is the purpose of this thing?"

Guo Zongxun secretly laughed in his heart, Zhou Guo has no horseshoe until now, which he didn't expect, he didn't pay attention to it before, but now that he knows, of course he has to give it immediately.

As for what kind of changes the horseshoe will bring to the warfare of this era......

It doesn't matter, it's faster and more brutal, and what should come is always coming.

Horseshoes can't be kept secret in any way.

"Father, the child named it the horseshoe, and the small nail was painted next to it, which was used to nail the horseshoes, and the horseshoes should be repaired and leveled with a knife before nailing, and the horseshoes would continue to grow, so after a while, the horseshoe should be removed and the horseshoes should be repaired again."

Guo Zongxun said with a gesture, Guo Rong's eyes were full of brilliance, he didn't expect that the problem that had been plaguing the Great Zhou army for many years was so easily solved by his own son.

"Xun'er, if what you say is feasible, my father's personal expedition this time is not to mention recovering Yanyun, it is possible to annihilate the Liao Kingdom."

Guo Zongxun said in his heart, it's not so exaggerated, having a horseshoe is just a better way to protect the horses, reduce the consumption of grain and grass, and the horses can fight in more harsh geological conditions, it seems to be nothing.

"Hehe, father, don't worry, it's guaranteed to be easy to use, today Erchen is busy with the winery, otherwise he must play a pair first, and his father will know it when he sees it."

Guo Rong's heart moved, looked at the paper, and then looked at Guo Zongxun:

"This horseshoe is a top secret of the soldiers, and it can't be built casually."

Guo Zongxun laughed and said:

"Father, as long as this horseshoe is on the battlefield, it can't be kept secret, and even if it is kept secret, it can only be kept secret for a period of time, and besides, not only war horses can be used, but all livestock with hooves can be used, such as horses pulling carts and ploughing cattle in the fields......"

Guo Rong patted his head, too, he was shocked, indeed as Xun'er said, this horseshoe can't be kept secret forever.

"Li Tongjie, pass on my message, let the Ministry of Works, the squire, and the master craftsman rush to the craftsman's office overnight to wait, and let Han Lingkun lead people to surround the craftsman's office, and he is not allowed to enter or leave."

Guo Zongxun knew that this was Guo Rong's plan to keep it secret for as long as he could.

"Father, I also have to tell General Han to be kind to those craftsmen."

"Yes, Xun'er is right, treat those craftsmen well, send people to appease the craftsmen and their families, and say that they can't leave the craftsman's house for the time being, so that they don't worry."

"The old slave obeys."

Guo Rong walked back and forth in the imperial study excitedly, and there was a glint in his eyes from time to time, if this horseshoe could really be used, I would have the certainty of victory in this battle against the Liao State.

"Father, the son has another gift to give to his father."

Guo Zongxun decided to strike while the iron was hot.

"Xun'er, tell me quickly, what is another gift, and what drawings are there?"

Guo Zongxun said with a smile:

"Father, there are drawings for this gift, but Erchen has already taken it to make it for people to rush to make, and this thing can be kept secret for a long time, so Erchen will arrange ......"

Guo Zongxun reported to Guo Rongyu about today's forced recruitment of Cuijia Liquor Workshop and the arrangement of Taoist priest Liu Bowen to disperse the production of wine purification utensils.

"What can this purified liquor do? Isn't it still for drinking? ”

"Father, but not only that, my father has led troops to fight all year round, and there are many dead and wounded soldiers, and a large part of them died because of festering wounds?"

"That's true, my father is also very worried about this, they are all good men of my Da Zhou, one by one, and they are all alive, but I can only watch them wail and die."

"Father, with this purified liquor, the sons dare to guarantee that the number of wounded people in the army who die due to festering wounds will be greatly reduced, and the wounded who are lightly injured will heal quickly."

Guo Rong looked at Guo Zongxun and was silent for a moment, how could Xun'er think of this? Could it be that the old lady doctor Guo Wanche told him?

"Xun'er, these methods were researched by you and Imperial Physician Guo?"

"No, it was Erchen himself who came up with it, Father, don't you have a little secret with Erchen, this is also a little secret between Erchen and Father, Erchen thinks that his father is about to go on an expedition, these two gifts are given to his father, I wish my father can be invincible and win a big victory in this expedition."

There's no way, I can't tell Guo Rong that he is a time-traveler, and there are many things in his mind that can change this era, so ...... I don't know what Guo Rong's reaction will be.

Purifying the liquor did not arouse Guo Rong's great interest, and what he was most anxious about now was to verify whether the horseshoe was really practical as soon as possible.

"Xun'er, you also work hard tonight, since it is a picture you draw, when you go to the craftsman to make it later, you will also witness it together."

"The retainers obey."

When the hour was approaching, news came from the craftsman's office that everyone had arrived by order, and that more than a dozen ordinary horses had been brought in for the experiment.

"Let's go, Xun'er, the time has come to witness the miracle."

Guo Zongxun said in his heart, Father, are you also a traverser, why do you always steal my lines.

Guo Rong drove lightly and rushed to the door of the craftsman's house with Guo Zongxun.

"Ministers, see the emperor."

"Excuse yourself from courtesy, the Ministry of Industry will stay behind, and the rest of the people will all enter the craftsman's house, and no one will be allowed to leave without my command."
