Just like Liu Ji dealing with Zuo Ding and Lian Gang, Li Xian's etiquette could not tell any fault, but immediately forced them into the corner.

"Governor Li, Zuo Censor is sick!" A clerk hurried to the government office.

Yuan Bin asked strangely: "What a coincidence?"

Li Xian smiled and said, "It's not a coincidence. I asked him to interrogate Jinshi and Juren from Ji'an and let him talk."

A layer of cold sweat immediately arose behind Yuan Bin. This Li Xian is really poisonous.

Zuo Ding and Lian Gang never expected that from the moment they attended the banquet, they fell into Li Xian's series of traps.

This series of condoms is called killing people and heartbroken.

Li Xian forced two people to stand in the same trench with him.

The officials who Zuo Ding impeached him are naturally responsible for the interrogation, which is very reasonable.

The one who is best at dealing with scholars is always scholars. Just as Yu Qian used a tube to subtly reduce the influence of Confucianism, Li Xian asked Zuo Ding to interrogate his fellow countrymen.

"What's wrong with you?" Li Xian asked with a smile.

Yuan Bin shivered and said, "You are too sinister."

"Is it insidious?" Li Xian was full of doubts, but he didn't feel insidious at all.

Yuan Bin sighed heavily. He would have gone to Ryukyu Kingdom if he had known it. It would be better to catch Japanese pirates there than to stay with Li Xian. He might have been sold at any time. I don’t know yet.

Li Xian was swinging the pendulum clock sent by the capital. The pendulum clock was assembled when he arrived in Nanjing, but after it was installed, it was not very accurate when leaving.

For this reason, Zhong Jiang conducted a variety of debugging to make it more accurate, but the length of the pendulum needs to be adjusted, but the specific adjustment needs to be continued experiments.

It is not only the local gravity acceleration but also the temperature that affects the pendulum clock, which makes Zhong Jiang unable to do so.

Yuan Bin asked curiously: "What's the use of you fiddling with this?"

Li Binyan also makes trouble in Songjiang Mansion all day long.

Li Xian smiled and said, "It's nothing, just verify some of the thoughts in my heart, what the world looks like."

Li Xian looked at Yuan Bin's expression that seemed to be ignorant and said with a smile: "It's like I can never understand how you caught Xining, the three brothers of the Qu family are like Zhao Mingrui."

"It is your military victory that guarantees my actions, so these ghost tricks of the literati are just ghost tricks."

"Your Majesty said that no matter how broken the house is, you have to kick it to completely collapse."

Li Xian stood up straight and said, "We need a clock that is not affected by temperature and does not need to be perpendicular to the ground. Otherwise, this watch needs repeated debugging by the watchmaker."

"This pendulum clock is useless."

Li Xian had some resentment in his words.

Yuan Bin took out the flintlock gun hanging around his waist, turned around and placed it on the table and said, "Governor Li, the musket was originally made of bamboo poles as the chamber and fireworks gunpowder.

The main purpose is to scare away the Mongolian horses."

"The earliest musket was just a firework, but now it is a weapon of killing."

Li Xian was a little surprised and said with a smile: "I'm so anxious."

He was actually taught a lesson by a military soldier to develop the truth.

Li Xian thought for a long time and said, "But I have to think of some solutions to speed up this process. For example, our legitimate emperor, King Xiang, provides a good solution."

"Sharp handle."

"After a heavy reward, there must be a brave man. I am going to use 50,000 silver coins to offer a reward of an accurate clock when traveling. No matter it is an hourglass, it will be enough to have an error of no more than an hour within two years."

Yuan Bin asked dumbly: "Fifty thousand silver coins? Is this too much?"

Lee Hyun shook his hand and said, "No, no, it is not expensive. I believe that Your Majesty will be willing to pay this reward and build a table that can get rid of this perpendicular to the ground. We need it to go accurately."

“Even if it’s just a way of thinking.”

"Because Li Binyan wants to go to the horizon to take a look, he needs such a clock."

Li Binyan needed an accurate clock to calculate his longitude, because at this time Li Binyan had already firmly believed that there was a ball under his feet.

So if you want to accomplish an unprecedented feat, this clock is what he needs the most.

At this time, Li Binyan was building the Songjiang Observatory at the Maritime Bureau of Songjiang Prefecture. Because a large number of new armillary spheres, Jian spheres, armillary spheres, Sanchen Gong Dingings and other astronomical instruments were sent from the capital, these instruments were conducive to Li Binyan's observation.

star.

His star-watching tower finally became a large observatory.

Li Binyan looked at the pendulum clock that was inaccurate when he walked, and could only sigh and rotate a tilted sphere in his hand.

This is a ball with a ground axis, an inclined ball, but there are dense lines drawn above the ball, which is the latitude and longitude.

Since receiving Ulube's information, he has easily calculated his own dimensions, but the longitude has been unable to be calculated for a long time.

"In fact, we can test the degrees of entry and exit from the ground and the latitude of the earth and the longitude and latitude of the earth wheels according to the Tang Yuan method, so as to determine the shortness of day, night, morning and evening, and whether there are orthogonal foods or not." Belin put forward his own idea.

His words mean that relying on the practices of the Tang and Yuan dynasties, the determination of longitude can be conducted using solar eclipse and menstrual events for specific inspection.

Specific implementation method - All localities should report the lunar eclipse time, carefully evaluate and make changes as they are made.

Astronomical phenomena are an important means to calculate longitude.

Li Binyan shook his head and said, "Eighteen years have been too long."

Every eighteen years, the sun and the moon will be above the Zhoutian and return to a similar position. Every eighteen years, forty-three solar eclipses and twenty-eight lunar eclipses will occur.

As long as you make a star map of the land under his feet for 18 years and identify the position of the moon on the star map, you can use the star map and the position of the moon to determine the time of the departure place.

This method is the moon distance method of the star-tracking technique. Of course, the calculation is actually more complicated. In addition to the star map, many other calculation rules are required.

It takes a long time to observe, consistently record the star map, accurately depict the position of the moon in the heavenly palace, determine the cycle, and go to the ocean with the thick star map.

And it will take at least eighteen years to fully draw the star map.

Of course, if you joke about your life with your fleet, you can set out directly. After all, he has the star map recorded by Zheng He's journey south to the West.

Belin argued: "In those eighteen years, we don't know if there will be accurate clocks."

Calculating the longitude is extremely easy. You only need to know the time of Tai'an Palace at this time and you can do it.

The 0° longitude line passes through Tai'an Palace, and calculates the difference in li and longitude, and adds east and west.

But they don't have an exact clock and are now stuck here.

"Li Xian has already offered a reward of 50,000 silver coins." Li Binyan said with great confidence: "Even if it is a way of thinking, as long as there is a way of thinking, so many craftsmen in the Ming Dynasty can make such a time-critical clock."

Belin spread her hands and said helplessly: "But where can I find such a way of thinking?"

"I don't know either." Li Binyan looked at the bulky pendulum clock and hated it for fear of fighting. If it could accurately time, Li Binyan could prepare for the Global Fleet at this time.

A tikka hurriedly ran into the Wanguo City Observatory and said panting: "Tang commanded him..."

"What's wrong? Is something wrong?" Li Binyan asked with a drastic change in his face.

"No, Commander Tang is back. He brought Huaiji, the national teacher of Ryukyu Kingdom has returned." The Tiqi finally finished speaking.

Only then did Li Binyan realize that it was not that Tang Xing was not making trouble outside, but that he was finally punished by God, but that he brought back an important figure.

The Ryukyu Kingdom's national conspiracy.

Huaiji was a scholar who had not passed the imperial examination. He sailed to sea, helped Zhongshan to unify the Three Mountains, and became the prime minister of Ryukyu.

Li Binyan breathed a sigh of relief and said with a smile: "Just nothing happens, go and take a look."

He changed his clothes, came to the Military Affairs Office of Wanguo City, and met Tang Xing.

"Commander Tang, I'm so happy to see you're fine." Li Binyan greeted with a smile.

Tang Xing sat on the chair with a big golden sword, and there was a monk sitting next to him. Huaiji was the host of Changshou Temple. Of course, neither Li Binyan nor Tang Xing regarded him as a host.

Huaiji manages the members of Tianshou Temple, and these members are important forces to protect the Ryukyu king Shang Jinfu at this time.

"Master Daoyuan." Li Binyan sat in the first seat and said solemnly: "This is not the time to pay tribute. According to the Ming Dynasty, even if you pay tribute, you should go to the Mizhou Maritime Bureau."

Huaiji had a few small boxes beside him. He opened the small box and said, "This is the yellow book and the fish scale book of the Ryukyu Kingdom. There are thirty-seven surnames in the Ryukyu Kingdom. Before Emperor Taizu Gao moved to the people, Ryukyu originally had no surnames.

.”

There are thirty-six surnames from Fujian and the king Shang family, a total of thirty-seven surnames.

Li Binyan took the yellow book and the fish scale book. The Ryukyu Kingdom had a total of 9,000 hectares of land, a total of 50,000 households, and a total of about 250,000 men, women, young and old.

"Master Daoyuan, what is this intention?" Li Binyan asked after taking a sip of tea.

Huaiji said with a clear thought: "Of course I want to ask the father's country to station troops to the officials. Ryukyu's heart is transformed into a king. If it is directed to the county, my king would beg to enter the court and never return to the Ryukyu's country."

In the early years of Yongle, the Chen family of Annan was destroyed by the Li clan. More than 120 elderly people in Annan invited Annan to Annan, the county of the Ming Dynasty, which led to the transformation of the Jiaozhi governor.

Huaiji's meaning is very clear. The King of Ryukyu and the people hope to imitate the old stories of Annan and naturalize the Ming Dynasty.

Huaiji clasped his hands together and said, "What's the use of the same text and the same kind of people? The sea of ​​all countries is well connected, and it is of great benefit to the Ming Dynasty. If Your Majesty does not intend to close all the Maritime Bureaus."

The importance of Ryukyu Kingdom to the Ming Dynasty's maritime trade is self-evident. You can see how important it is when you look at the pirates entrenched on it.

Li Binyan shook his head and said, "Ryukyu is a country that is not conquered. This is not something I can decide. Please send an envoy to the court and express your feelings to the emperor."

"The main reason is that the Zhoushan Navy of the Ming Dynasty has just started and cannot station troops."
