In the Zichen Palace.

The governors have already bid farewell and left, and even the two palaces have also left.

But Zhao Xu still stays here, and Di Yong also stays here.

Zhao Xu kept Di Yong in order to "teach him the instructions face to face."

Although it sounds exaggerated for a nine-year-old child to give instructions to an experienced general.

But considering the tradition of Zhao officials, it is normal - since Taizong, officials of all generations like to give battle plans to frontline generals.

It was not uncommon for the emperor to be far away in his palace in Bianjing City, but still separated by thousands of mountains and rivers, micro-managing the frontline matters.

The most famous one is the late emperor.

Five roads to conquer the summer, micro-manage every road.

It is said that at that time, there were more than a dozen or even twenty hurried horses departing from Bianjing every day.

As a result, riders on horseback kept coming and going on the road.

In addition, the battle of Yongle City is also full of micro-management.

Since the emperor, who knows nothing about military affairs, can dictate wars thousands of miles away, he also demands unconditional obedience from the generals on the front line!

So, it is completely reasonable for a young emperor who is self-possessed and smart to give instructions to a general who is about to set off.

The two palaces understand this very well.

After Zhao Xu announced that he was leaving Di Yong behind and wanted to discuss the matter face to face, he took his people back to Baoci Palace.

As soon as these people left, Zhao Xu asked Yan Chen to lead people and clear out everyone in Zichen Palace.

In the huge Zichen Palace, only a few ministers around Zhao Xu and the imperial guard Yan Chen led by Yulong Zuozhi were left.

Zhao Xu turned to Feng Jing and ordered: "Go and bring the things I have prepared!"

"yes!"

Feng Jinggong left.

Zhao Xu stepped down from the throne, walked down the imperial steps, and came to the palace.

Yu Longzhi, whom Yan Chen brought with him, was always guarding him.

"Di Qing!" Zhao Xu looked at Di Yong.

Di Yong immediately bowed: "I'm here!"

"Your father once put down the rebellion of Nong Zhigao in the past. You are more familiar with Guangxi's geography and folk customs than I am! I don't need to say more about this matter!"

"Don't dare!"

"You serve in various places and lead troops to fight. I don't love you as much as you do about military affairs, so I won't say much about it!"

"I'm scared..." Di Yong quickly lowered his head.

Zhao Guanjia's reputation for micro management is popular all over the world.

The generals have long been accustomed to it and have even developed their own countermeasures.

Like Zhao Xu, he made it clear that he would not interfere in strategic or military matters.

It is extremely rare throughout the ages!

"So, I will only teach you a few little marching skills!"

By this time, Feng Jing had returned.

In his hand he held some strips of burlap.

This kind of cloth was the cheapest cloth in the Song Dynasty, and it was also the material used by most ordinary people for daily clothing.

"The first one is leggings!" Zhao Xu clapped his hands and said to Feng Jing: "Feng Jing, show Di Aiqing how to leggings!"

Leggings are a skill that Zhao Xu learned from the archaeological team in modern times.

It is said to come from experience during the war years.

Gaiters can improve the infantry's marching efficiency and speed, reduce muscle soreness, and even varicose veins.

It is the best marching auxiliary equipment for light infantry.

After Zhao Xu practiced it, he was convinced.

With leggings, walking in the wild, especially when climbing mountains and ridges, becomes much easier.

Moreover, the legging straps can also be used as a tourniquet in emergencies.

Di Yong looked at the cloth strips, and then watched Feng Jing in front of him, holding the strips of cloth and skillfully wrapping them around the calf starting from the toe of the shoe.

While wrapping it up, he also explained the key points: "General Di, this leggings should be worn while standing. It is most comfortable..."

"Every one or two turns, turn the wrong side of the strap upwards..."

"Not too tight, not too loose..."

"It's better to hit it all the way to the crook of your legs!"

Di Yong looked at the simple movements demonstrated to him by Feng Jing, although he still didn't quite understand what they were for.

But this is something that the emperor ordered his people to demonstrate in person.

Even if it is a completely useless burden, at least it must be promoted throughout the army while it is in Bianjing City.

This is respect! It is also a kind of surrender!

Feng Jing tied the strap on his left leg and then danced in front of him.

"General, please see, after these leggings are put on, they should fit perfectly with the shoes...so that even in the wild, you won't have to worry about insects and ants biting your legs!"

Di Yong's eyes lit up as he listened.

When his father was still alive, he said that the biggest problem encountered during the expedition against Nong Zhigao was the rugged mountain roads of Guangnan West Road and the bites of insects, ants and leeches.

Guo Kui and Zhao Xi Nanzheng also suffered greatly from insects and ants!

Therefore, when Di Yong looked at those cloth strips, his eyes lit up as if he had seen a beauty!

This alone can save the sergeant from countless illnesses!

"In addition, after wearing these leggings, you may feel some swelling and pain in the first few days, but you will get used to it after a few days!"

"Moreover, it can make soldiers march more easily! It has been tested in Ouchi. The ministers wearing leggings can walk around Ouchi several times a day without feeling any pain!"

Di Yong's eyes brightened as he listened.

If it really has such an effect, this is an artifact!

He immediately bowed and said, "Your Majesty has given me this gift. I would like to express my gratitude to you on behalf of the officers and men!"

If it really has such an effect.

Even if it only allows the army to travel an extra twenty miles a day.

For the thieves, this is already a dimensionality reduction blow.

It can make the Song army appear unexpectedly in places that the thieves and bandits could not imagine.

Zhao Xu smiled and said: "Di Qing, don't be too hasty to thank me..."

"I have also prepared a lot of things for the army!"

He clapped his hands and something in a small porcelain bottle was brought over.

Zhao Xu took the porcelain bottle in his hand and opened the cork.

After smelling it, he laughed and said, "That's the cool smell!"

"Please come and smell it too..."

Di Yong took the porcelain bottle, put it in front of his nose and smelled it. A strange fragrance with the taste of mint and mugwort came to his nostrils. It gave him a refreshing feeling!

"What is this?" Di Yong suddenly became curious.

"This is a kind of medicinal wine specially produced by the Royal Pharmacy Institute. It's called toilet water..."

"I won't tell you the formula. All you need to know is that this product can be applied to mosquito bites to effectively prevent wounds, itching and abscesses..."

Di Yong's eyes suddenly widened.

Zhao Xu smiled.

Why did Liu Weijian stay in the Imperial Concubine Pavilion and the Imperial Medicine Hospital, and was only sent by Zhao Xu to review the accounts of the Detective Department a few days ago?

Just doing this.

First, the distillation technology of alcohol was solved, and then it was soaked with mint, mugwort, camphor, borneol and other substances.

Of course spending money is spending money!

More than a thousand kilograms of toilet water cost at least one thousand or two thousand guan.

This does not include the cost of distilled liquor.
