Jiang Fa took the drawing and looked at it carefully, but he couldn't help but exclaimed: "Huh? Why is it so similar to the Bagua Pan?"

"Oh?" Zhuge Xian and Qiao Xiu both raised their heads. After a moment, Zhuge Xian shook his head and said, "There is still something different. There is no pointer in the middle of the Bagua disk."

Qiao Xiu then added: "If you look carefully, the Bagua Pan divides the Heavenly Stems, Bagua and the Twelve Earthly Branches into three levels, with unequal shares. However, the navigation compass drawn in the picture divides the compass into twenty-four levels.

There is a small gap between each equal part. I counted it and it was equivalent to dividing the compass into forty-eight equal parts. This is wonderful. In this way, it will be very easy to locate at sea. However, the pointer is also

What’s the use?”..

The nautical compass first appeared in the Song Dynasty. Its forty-eight directions are spaced seven and a half degrees in each direction, which is much more accurate than the thirty-two-way compass in the West. The place where the compass is placed on the ship is called the needle room, and no idlers are allowed to enter.

Experienced sailors take charge.

In fact, according to Yunfeng's original intention, he wanted to make a sextant. The scientific principle of the sextant is very simple, that is, the reflection angle of light is equal to the angle of incidence. The manufacturing process is not complicated, but the key point is.

Reflective glass is needed, which means that the intensity of light is reduced by half after passing through it. Obviously, under the current technical conditions, reflective glass can only be a beautiful dream, and it will have to be explored in the future when the overall technology improves.

Facing Qiao Xiu's puzzled gaze, Yunfeng explained: "The pointer in the center of the compass is called the compass. It is ground with magnets. Its principle is the same as that of Sinan. You can use it to determine the direction of due south. Then follow the scale on the compass. From then on.

There will no longer be any risk of getting lost when sailing. However, it is quite troublesome to make a compass. The needle body must be as light as possible, and the contact point with the center bearing of the compass must be

It should be as smooth as possible to reduce unnecessary resistance. Otherwise, it is likely that the ballistae will not be able to rotate. Or it will not be able to rotate fully, which will affect the positioning precision. In this regard, Jiang Gong will have to worry more. In addition, the crossbow

We cannot abandon the manufacturing. Before next summer, every warship in the Liangzhou navy must be equipped with a ballista. I wonder if there are any difficulties?"...

Jiang Fa cupped his hands and said, "Please rest assured, Your Majesty, I have just considered this. I have sent some of my disciples and craftsmen to Jiangzhou to make it locally. I think it should not be a problem. As for the compass, I will do my best."

." and took the drawing into his arms.

Yunfeng looked satisfied, nodded and said: "After making it, if there are no mistakes, immediately send the compass to Liangzhou, install it on the battleship, and train people who are proficient in celestial phenomena and directions to specialize in positioning, so that they can become familiar with it as soon as possible.

After a while I will go to sea to find silver mines."

Just as he was talking, Yunfeng let out a long sigh: "Hey~~ The cost of acquiring hundreds of thousands of hectares of land from the wealthy clans in the west is probably unimaginable. With only the gold and silver in hand to pay for it, there is still a lot of money left.

The gap, and the navigation compass is related to whether overseas silver mines can be found, its importance is self-evident, please Jiang Gong must develop it."

Everyone couldn't help but feel a trace of sympathy in their hearts. It was a strange thing in ancient times for the king to be treated like this. He lived a relatively simple life, and he was reluctant to charge even a grain of rice from the people, and he had to go to great lengths to do so.

To get money, even prospecting for minerals

This kind of thing has to be done personally. Logically speaking, prospecting for minerals is not what the king should do, but they all know that besides himself, there is really no other person in the world besides himself for the overseas silver mines that Yunfeng often talks about.

Knowing where Baoshan is, he had to run this time even if he didn't want to.

The three old guys were all in awe. With their wisdom tempered by the vicissitudes of life, they could see that everything Yunfeng did was not for himself. Although there were some things that they did not understand, it did not prevent them from understanding.

, this is seeking happiness for the people all over the world!

Jiang Fa bowed solemnly: "Please don't worry, Your Majesty, I will definitely succeed in making a navigation compass."

Yunfeng helped Jiang Fa up and said with a slight smile: "Mr. Jiang, please get up quickly. Be more patient and careful. Don't put too much pressure on yourself."

"Your Majesty is right!" Jiang Fa stood up in accordance with his words, looked at Zhuge Xian and Qiao Xiu, and then cupped his hands: "I came here today to pay a visit to your Majesty. Since everything is over, let's take our leave.

Already."

Yunfeng nodded and said, "That's fine. Things are complicated now. When they settle down, we can have a drink and have a good time. Mr. Jiang, the teacher, the master of the Zhuge Sect and the Tianji Sect's mansion have been arranged. We will leave later."

Someone will lead the way from the palace gate." After saying that, he turned back and called: "Miss Zhuge, please send off the three teachers with your husband."

Zhuge Fei nodded and stood up with Xiaolan Xiaohui.

"Hey~~" Qiao Xiu waved his hand and said: "There is no need to see each other off in Duanshan, and we are not traveling far away. We three old guys can just leave on our own. Why bother?" After saying that, the four of Yunfeng did not wait for anything else.

He said, he cupped his hands with Jiang Fa and Zhuge Xian, turned around and walked out.

Watching the backs of the three fluttering sleeves gradually go away, Xiaolan urged: "Your Majesty, let's go back quickly. If the sisters can see this astronomical telescope, it will definitely be very novel."

Yunfeng's mind also showed the fuss made by the women. He has three major goals in life. One is to make the country rich and strong and the people to follow the path of hegemony. The other is to reach the peak of martial arts, and then explore whether there is another breakthrough.

possible, although

Yunfeng talks about atheism when he meets everyone, and he agrees with atheism intellectually, but subconsciously, he is not willing to turn into a pile of dust in a hundred years, and also fantasizes about one day ascending to immortality. In fact, this is normal, the more powerful the

The more people are afraid of death.

No one knows whether immortals exist or not. In Yunfeng's imagination, the legendary immortals are just human beings who have broken through their own limits and evolved into more advanced life forms. Therefore, Yunfeng sincerely hopes that Master Wu Pu will become an immortal and points out a clear path.

Lu Lai. The third point is to bring joy to the women around you. Judging from the performance of Xiaolan and Xiaohui, the astronomical telescope will definitely cause a sensation.

Secretly suppressing all thoughts, Yunfeng put his arms around Zhuge Fei's slender waist and said with a faint smile: "Let's go, there should be nothing else to do these days. My husband will stay with you."

"Yeah!" Zhuge Fei snuggled up to Yunfeng, followed by Xiaolan Xiaohui, and walked out together.

Not long after, the four people and two children had returned to the back hall. Yu Wenjun had the sharpest eyes and saw a cylinder in Yunfeng's hand at a glance. He immediately asked: "General, what is that in your hand?"

?”

Yunfeng responded casually: "This is an astronomical telescope. Through it, small objects will become very large."

"Oh? Is it really so magical? Then Wenjun needs to take a look!" Yu Wenjun stepped forward and grabbed it, looking at Yunfeng unceremoniously. After a while, he took it away and said suspiciously: "Why is everything there?

Can’t see it? General, are you bragging?”

"Huh?" Yunfeng then realized that Yu Wenjun was holding it upside down, with his big head facing his eyes. It would be damning if he could see this, but he didn't prompt him and just looked at him like an idiot.

Yu Wenjun was most sensitive to eyes. As if he had been greatly humiliated, he glared back at Yunfeng, but he was unwilling to ask Yunfeng for advice, so he turned around and asked: "Sister Xiaolan, sister Xiaohui, you guys

Those who came back with the general should know how to use it?"

Xiaohui covered her mouth and chuckled: "Wenjun, if you hold it upside down, put the little head towards your eyes and you can see."

Yu Wenjun's pink face quickly showed a small layer of red clouds, and she cursed herself in her heart. She was so embarrassed, especially for showing that person a joke! She looked at Yunfeng without anger, and turned the telescope in a different direction.

Watched it again!

Suddenly, a burst of laughter broke out. Yu Wenjun laughed so hard that she couldn't even straighten her waist. Her smile was different from other people's. People's laughter stopped and she kept laughing.

, looking like no one else was around.

Except Zhuge Fei and his servants, all the girls looked at Yu Wenjun in confusion, but Yunfeng's face became darker and darker. He stood still and was pointed at and laughed by a woman for a long time. No one could bear it.

"Ahem~~" Yunfeng coughed twice and said displeasedly: "Director Yu Women's Federation, you should be at the Women's Federation at this time? Why are you still here?"

"Ah?" Yu Wenjun was startled. Yunfeng's question was like a blow to the head, causing her laughter to stop abruptly!

Yu Wenjun's eyes were a little erratic, and he did not dare to look directly at Yunfeng, and said sarcastically: "The senior sister is in retreat, and Wenjun is worried, so he stayed and waited for the senior sister to successfully break through before going back."

Yunfeng exposed it mercilessly: "Miss Yu, what's the use of staying in Lingyun retreat? Yigu thinks your enthusiasm has faded. If you don't want to do it, just say so and I won't force you.

"

It turns out that training members of the Women's Federation is not as easy as imagined. Although the middle-aged women they found met the standards, their consciousness was not high. Either the law enforcement was excessive, or they were too timid and shrank as if they were different people, female Rakshasa.

Several drills arranged secretly did not meet the requirements.

Take the most recent one, for example, a family forced the widow to remarry due to property issues. Of course, all the parties involved were pretending, but the members of the Women's Federation didn't know that the female Rakshasa brought them there to do work.

He used words to persuade and educate, but instead besieged and cursed, which was completely contrary to Yunfeng's original intention. Yunfeng did not want to ruin the image of the Women's Federation, so he had to extend the training period, and Yu Wenjun was too busy to go.

Yu Wenjun's heart trembled, how embarrassing it would be to be kicked out! She looked at Yunfeng with some evasion, but she snorted coldly: "Humph! Wenjun knows that General, you just can't see Wenfeng.

You are idle, forget it, Wenjun is blocking your eyes, why don't you leave?" After saying that, he handed the binoculars to Su Qizhen beside him, and walked out alone.

Su Qizhen was also very curious and immediately put the eyepiece into her eyes. However, she just glanced at Yunfeng quickly, then suppressed a smile and moved the camera elsewhere. After a while, she handed it to the next person.

A group of women, big and small, looked at each other. They looked at everything, hillsides, trees, birds, animals, palaces, but most of all, they looked at each other. Everyone was trembling with flowers, and they giggled one after another.
