"Fourth, I wonder if the prince knows about Sinan?"

The front hall of Li's house.

Li Zexuan looked at Li Xiaogong and asked.

"Of course I know, how many of these things are in Qin Tianjian, what's wrong?"

Li Xiaogong replied strangely.

According to the Record of Ancient Mines, Sinan first appeared in the area of ​​Cishan, Hebei during the Warring States Period. From Sinan to the compass, a very long time has passed in the middle, at least the compass has not appeared in the early Tang Dynasty.

Qiu Yanhan, a Kanyu family in Shanxi during the Kaiyuan period of the Tang Dynasty, was praised by later Kanyu family as the founder of the earliest positive needle method in the three needles of Kanyu (positive needle, sewing needle and middle needle). This person may be the earliest inventor of magnetic needle. .

In the early years of the Northern Song Dynasty, our country created a guide tool, the guide fish, which is made of a thin steel sheet and is shaped like a fish. It is two inches long and five minutes wide, and the belly of the fish is concave. Like a small boat, it can float on the water. A fish made of sheet steel is not magnetic, so there is no guide. If you want it to guide, you must use the method of artificial magnetism to turn it into a magnet and have magnetic properties.

Zeng Gongliang of the Northern Song Dynasty and others compiled the "General Essentials of Wujing" using the information of predecessors, and introduced the preparation method of guide fish in detail. As for the production method of the water-floating magnetic needle, it was first seen in "Mengxi Bi Tan" by Shen Kuo of the Northern Song Dynasty. The application of the compass in navigation was first used in the Ming Dynasty when Zheng He went to the Western Ocean.

In this era, even if the compass was invented, it is estimated that no one would think of using it for navigation.

That's right, the gift that Li Zexuan wants to give to the tens of thousands of people is the compass. This thing is a weapon for navigation. In the Song and Yuan dynasties, the compass invented in my country spread to many countries in Europe and Asia, making modern Oceanic exploration in Europe became possible, of course, the European countries, relying on ocean voyages, established colonies, and completely rose, and we...  

"My lord, Sinan's spoon handle can point to the south no matter how it is rotated. Through it, we can identify the direction in the vast sea! This way, we won't get lost."

Li Xiaogong's eyes lit up, although he had never been to the sea, but he didn't know how many water battles he had fought, he said excitedly: "Haha, you have so many crazy ideas, only you can think of using Sinan for sailing. Yes! But..."

Having said that, he frowned and said, "But Sinan is too large, and it may be inconvenient to place it on the boat."

Li Zexuan said with a smile, "You don't have to worry about this, my lord. The kid knows there is something, he can also point out directions, and he is extremely light and easy to carry. If the lord needs it, the kid can make a few in the workshop today and send them to the palace. When the time comes, the lord will know when he sees it."

"Is there really such a fetish? Then you have to make it as soon as possible. It's only a few days before the army starts!"

At this moment, Li Xiaogong is really glad that he came here today, and the harvest is so great!

Li Zexuan was about to nod his head when he suddenly remembered something and said, "The boy is very willing to help the prince, but recently the boy is still in the period of confinement, and he cannot go out or go to the workshop in person. If this happens, the progress will be much slower."

Although the restraining order allows him to take many days off, if he needs to go out for something, it is indeed inconvenient. For example, today's "Datang Daily" was revised. When he came up with an idea yesterday, he had to write a letter to teach Ma Zhou and the others. How to change, how can it be convenient to say face to face.

Li Xiaogong said nonchalantly: "This is not a big deal. This king will go to the palace in a while and ask Your Majesty to suspend your foot restraint order. The military situation is urgent, and your Majesty will surely accommodate this trivial matter."

Li Zexuan said happily, "Thank you, my lord!"

"It's alright, so what do you need to say about the things that you need to pay attention to when going to sea, Xiaoxuan?"

"There's a little more."

Li Zexuan pondered: "My lord, this time the 20,000 navy army, the boy suggested that the lord choose as many elite soldiers as possible, who can not only win the water battle, but also the land battle, and the weapons should be well prepared."

Li Xiaogong's eyes flashed, and he said coldly, "Xiaoxuan, what do you mean... we will not only encounter water battles, but also fight against others on land?"

Li Zexuan nodded and said:

"Well, it's quite possible. It's possible to encounter pirates on the water. As for the land... My lord, the goods you carry in this fleet are all of great value. Those gorgeous silks and exquisite china are very important to Nanyang. For the people outside the transformation, it is tantamount to being more precious than gold, and there is no guarantee that they will not be malicious.

If you are a little careless, the 20,000 troops led by the prince will be attacked by those small countries with all the strength of the whole country, and the entire fleet will also fall into the situation of being attacked by the enemy on their backs and bewildered on all sides. The original intention of the fleet going south this time is indeed for trade, but the heart of defense is indispensable. If others take the lead in trying to break the rules by force, I think that at that time, the lord does not need to be merciful, right? "

Li Xiaogong frowned and said coldly, "Fanwai Xiaoguo, if you dare to offend the tiger power of my heavenly kingdom, this king will definitely draw his sword and drink blood, and raise my great Tang Tianwei!"

Li Zexuan praised: "Your Highness is really bold!"

He looked at the hour, and continued:

"It's not too early now, why don't Wangye and Uncle Qin eat at the boy's house!"

Li Xiaogong laughed and said: "I heard that your kid is eating and drinking, and you are quite accomplished, so it happens that this king is in your house today, and you can taste your food and wine, haha!"

Qin Qiong also nodded and smiled: "Haha, hehe.

It should be like this, count the days, Xiaoxuan, you and Yuxi are about to get married. As Yuxi's adoptive father, I haven't eaten at your house yet! "

Li Zexuan said sweaty: "Cough, it's the kid who didn't think carefully!"

"Ha ha!"

the other side.

Meng Wenhao read the newspaper on the pier for a long time, and naturally he focused on the last few paragraphs of the newspaper several times. He was really moved by the generous rewards for writing novels, and he also started to write novels in his spare time. The idea, but he just thought about it, and immediately rejected it.

First of all, the study at the Suanxueguan is already very intense and the competition is very fierce. He also thinks that he will be the first in the monthly exam and get the opportunity to take his family to the Zuixianlou for a free meal. Let’s eat and drink in Zuixianlou, at least 50 or 60 sticks. If you order drinks, it will be more expensive. This is more cost-effective than writing novels!

On the other hand, writing novels will definitely delay your studies, his father and his mother will definitely not allow it, and he will not allow it either.

Shaking his head, he dismissed this unrealistic thought. Meng Wenhao looked at the sun above his head, and then got up to go home for lunch. At this time, he realized that he was actually near Yongdafang, and he was blind all the way in the morning. Wandering, unknowingly came to a place so far away from home.

Meng Wenhao sighed and walked home.

"Don't move! Robbery!"

When walking to Xuanyi Square, Meng Wenhao suddenly heard a deep male voice coming from the lane between Xuanyi Square and Feng'an Square. He was shocked, and quickly turned to the corner of the wall, carefully peeking at the situation in the alley.

I saw a big man in a gray shirt, with a black cloth pulled from somewhere on his face, holding a cold kitchen knife in his hand, which was placed on the neck of an eleven- or twelve-year-old girl. It is a picture of robbery in broad daylight.
