When Yuan Ling arrived at Wen Bide, he was no longer in a hurry to go out to Bofang to make money, and he couldn't stay at home. He went out again and went to the Ministry of Works.

With Li Shimin's permission, he allowed him to view various drawings stored by the Ministry of Works.

Yuan Ling has been raising money these days, and has no time to make up for the architectural knowledge of this era. He decided to stop first and study for a few days first, and also give the major Bofangs in Chang'an time to come to pay the money.

Because there is no general and reasonable statement about load bearing, building area, etc., the drawings of this era are recorded in particular in detail, and those who are interested in step by step can understand it at a glance.

What Chinese people are best at is learning.

After Yuan Ling's career in the Tang Dynasty over the past few months, it was a bit difficult to dig into articles written by literary masters. But things about architecture are easy to eat.

It was not until the Ministry of Works that Yuan Ling reluctantly left the Ministry of Works.

The drawings stored in the Ministry of Works are not only about construction, but also have many secrets: battlefield killing weapons such as arm-opening crossbows, horn-opening crossbows, wooden single crossbows, large wooden single crossbows, bamboo pole crossbows, large bamboo pole crossbows and Fuyuan crossbows, as well as various stone throwing machines, siege vehicles and other siege weapons.

Therefore, Yuan Ling could only study it in the Ministry of Industry and could not bring out the drawings.

When the rooster crowed, Yuan Ling habitually opened his eyes and finished washing up under the service of his maid.

First, he ran around the huge Da'an Palace in the cold air. After getting warm, he got into the study and studied He Chou's letters.

This is a habit developed by Yuan Ling in ancient times.

The biggest advantage at this time is that there are too few distracting things, no TV, no mobile phone, no computer, and watching TV shows, chatting and playing games, all of them have become fantasies.

There is almost nothing to pass the time. When you go out to visit relatives and friends, sometimes it takes two or three hours to travel.

Reading and exercising, a healthy life, is the best way to pass the time for Yuan Ling, who doesn’t have to worry about food, clothing, housing and transportation.

"Your Highness, Luo Tong is here!"

Yuan Ling didn't go to the Ministry of Works today, and he was waiting for Luo Tong.

"Let him come to my study!"

Yuan Ling did not treat him as an outsider and directly invited him to the study.

Soon, knocking sounded.

"Come in!"

Yuan Ling put down the letter in his hand with great interest and looked outside the door.

A young man in his early twenties strode into the room, clasped his fists and said, "I've seen the King of Shang!"

Yuan Ling looked at the visitor carefully and nodded with satisfaction. Luo Tongchang was not as handsome as described in the novel, but he was also a sunny boy with thick eyebrows and big eyes, high nose and deep eyes, wide shoulders and narrow waist and long legs, and a healthy and shiny skin tone.

At first, he still had a little worry in his heart. After all, Luo Tong in the novel was a fascinating girl. If he really wanted to bring a handsome and undespicable guard to attract attention everywhere, he would be too embarrassed to be too embarrassed.

Yuan Ling didn't understand martial arts, and could not see the depth of Luo Tong, but from his upright figure and the thick calluses exposed on the tip of his fists when he clasped his fists, he could also see his hard work in his past training.

Just looking at the surface is much better than those free guards.

"No gift!" Yuan Ling waved his hand and said, "I don't pay attention to the vain rituals, just be as good as you want. Since you are here, just do it well. You can do it at will in the mansion. There is a martial arts training ground opposite, so you can practice it yourself. There are many books in the mansion, including military strategies and even some lonely books, which you can read by yourself. When you leave the mansion, I will let you notify you."

Luo Tong was instantly moved. He had also been in this business before. To put it bluntly in the account, this marriage was just a guard. In addition, he had a bad reputation and arranged for him to stand guard and run errands.

Especially some time ago, Yuchi Baoqi and Yuchi Baohuan made things difficult for him, and he had the idea of ​​going out to hunt and make money.

Instead of being cowardly, it is better to make money and hand over the money for the sub-class.

Yuan Ling took this unexpected appearance and gave such conditions, and almost blurted out his words.

"Thank you Your Highness for your kindness!" Luo Tong bowed deeply: "If Your Highness likes this, Tong should not refuse, let alone negotiate more conditions. It is really because his mother is sick and staying away for a long time, which is against filial piety."

"That's it!" Yuan Ling pondered for a moment: "Filial piety is the first of all virtues. It is rare for you to have such filial piety... What disease did your mother suffer from?"

Luo Channel: "Wind and cold, evil energy invades, and every winter, my feet hurt unbearable. My mother was injured in her left leg when she was young, and her legs were a little uneven. This weather changed, and this was even more so."

Yuan Ling said: "Then this way, I can arrange for the imperial doctor to see your mother. As for you, you don't have to follow me all day long. I won't go out in the short term, you can serve your mother as much as possible. When I need to go out, I will send someone to inform you, and you will arrive at my mansion on time the next day. You don't need to live in my mansion. Da'an Palace is next to the imperial city, and it's very safe here."

Luo Tong stayed for a while, never expected that Yuan Ling was so easy to talk to. He even specially asked the imperial doctor to treat his mother. He didn't know what to say for a moment, and thousands of words finally turned into a sentence: "Thank you for your great kindness."

Yuan Ling paused and suddenly said, "You said, your mother's legs and feet are not smooth, and she cane is used? What's the point?"

Luo Tong was a little confused and said, "It's just a very ordinary crutch..." He reached out and gestured, it was the ordinary stick.

Yuan Ling asked again: "How tall is your mother probably?"

Luo Tong was even more confused and said, "Five feet per..."

"Wait a minute!" Yuan Ling strode out of the study and walked to the backyard.

Most of the carpenters hired before were recruited by the Ministry of Works. Yuan Ling later recruited some carpenters from Chang'an, mainly to make some small roof beams and small house frames.

Nothing else, it is just to study mortise and tenon technology.

The real core of building houses in this era is whether the mortise and tenon can be used reasonably to reduce the use of iron nails.

You should know that the smelting technology of this era cannot be compared with later generations. The time when iron nails decay is much faster than that of later generations, and there is even more no way to keep up with the number of wood.

The less iron nails are used, the longer the life of the house will be.

"Stop everything in your hands!" Yuan Ling clapped his hands, gathered the carpenter beside him, pulled out the sword from his waist, drew a armpit stick on the ground, and asked the carpenter to make it accordingly.

Sticks are useful, but to be honest, they are not used by people who have no problems with their hands and feet, or those who climb mountaineering, who have suffered injuries to their hands and feet and are difficult to walk. Sticks are not very useful, but they will have certain risks.

The armpit stick is different. It is invented for patients who are injured in legs and feet. It is a walking device that uses the armpits and hands to support it, which is very practical.

All Yuan Ling recruited good players, making simple armpit sticks is completely effortless.

Soon, two armpit sticks made of top boxwood were formed under the Miao hand.

In order to prevent slippage, Yuan Ling also cut a piece of wolf skin and wrapped it in the tips.

After polishing and rounding it with fine sand, Yuan Ling walked towards the study with two crutches.

Luo Tong had already heard the sound of footsteps, and stood aside with a letter in his hand, saying awkwardly: "I accidentally saw this book "Wu Zi's Art of War" and felt itchy..."

Yuan Ling smiled knowingly and said, "I said it a long time ago, you can do whatever you want." As he said, he clamped the armpit under his armpit and said, "You think, this is prepared for your mother. This crutch is made according to your mother's height. I am much taller than your mother, so it is a bit inappropriate. There will be no problem with your mother using it."

Yuan Ling was playful when he was a child, broke and retreated, and used this thing, so he remembered the method of using it. He explained in detail: "There are several ways to walk this type of crutch. You can write it down carefully and teach your mother: First, put it to the steps, mainly using the muscles on both sides to complete it. The walking is stable and practical, but the speed is slow, and it is suitable for uneven roads, crowded people, and crowded occasions." He said, pointing at his latissimus dorsi.

"Second, when the sway is swung, it is often applied after the sway is successful. The stride is larger and the speed is fast. It is suitable for occasions where the road surface is wide and there are fewer pedestrians."

"Three, four-point walking, the walking speed is slow, the stability is good, and the gait is similar to normal walking. This walking method is less difficult and suitable for beginners to recover in the early stages of recovery and is also one of the most practical walking methods."

Yuan Ling introduced the functional effects of the crutch to Luo Tong in detail.

Luo Tong looked at Jingzhen Yuan Ling with a trace of shock and emotion flashed in his eyes. He carefully wrote down all the details one by one, then bowed deeply and thanked: "Your Highness is so kind and great, Luo Tong cannot repay you. I wish to protect Your Highness for your marriage."

He said word by word, especially cautiously.

Yuan Ling waved his hand and said, "I have not planned to travel far these days. You can go back and accompany your mother. By the way, bring him my gift and say hello to me."

Luo Tong said goodbye, "As for your order!" He strode to the door, turned around and bowed deeply.

Yuan Ling waved his hand again and said, "Go!"

Seeing Luo Tong leave, Yuan Ling smiled knowingly. His previous actions were a bit intentional and sincere.

In this era, if you want to achieve a little success, you can't do anything without a few loyal subordinates.

Luo Tong has courage and a story on him. He is not the old fox of Wei Zheng. He can guess what he ate if he makes a secret fart. After a lot of thought, no one will be sure of anyone who plots. It is just right.

Even if you can't take it for yourself, you won't lose money by treating it as a friend.

Yuan Ling is quite open-minded and makes money from both sides and enjoys it.

On the next five days, Yuan Ling either studied the mortise and tenon technology in his mansion or went to the Ministry of Works to read the architectural drawings and deeply study the architecture of this era.

After five days of struggle, the major bofangs in Chang'an finally couldn't stand the pressure and chose to compromise.

They went to Da'an Palace to pay money one by one, without exception.
