Chapter 283

Every day in the school of Bowen and Wang Fu, another new year will soon pass.

On the fifth day of the first month, the government institutions in Qingzhou basically returned to normal operation.

The common people can enjoy the new year until the 15th of the mid month, but Xiao Ming can't be intoxicated with it. He always reminds himself of this.

For the course of maritime positioning, Xiao Ming talked for a month, during which he also talked about how to test the speed.

After a month's theory, Xiao Ming decided to let Yue Yun and others practice.

"Your Highness, the naval guns are all on board now, and the task of our military workshop has finally been completed."

In Xiaoqinghe shipyard, Chen Qi was relieved to see the last gun being hoisted onto the ship.

During the Spring Festival, the military workshop was not idle. All the craftsmen worked day and night and finally delivered all 150 naval guns.

Starting from Xiao Ming's trip to Cangzhou, it took three months to produce this naval gun, with an average of 50 guns per month.

Similar to the city gun at the head of the city, the naval gun belongs to the heavy gun, which belongs to the 32 pound gun according to the gun standard of Qingzhou. Moreover, 60% of the shells on board this time are normal solid shells, while the remaining 40% are grape shells.

According to Xiao Ming, grape shells are actually naval shells, which are specially used to bombard other ships.

Zhang Liang looked at the Galen ship and the artillery on the ship and said to Yue Yun, "Yue Yun, you should be careful when you go out this time. It costs 300000 taels of silver to build this Galen ship. It's not a ship, it's silver."

Chen Qi added: "it's more than that. All the naval guns on board this time are about eight or nine kilos. The cost of each gun is about five thousand taels of silver. The 150 guns are about seven hundred and fifty thousand taels of silver."

When they said that, Yue Yun's forehead was sweating. He looked at Xiao Ming and said, "Your Highness, look at them. How can I sail the Galen to sea?"

"What they said is also true. These three galleons are more than 1 million taels of silver. Yue Yun, when you get to the sea, you can't fool around. Remember that your mission is not to fight, but to explore. Although our ships are small, they are flexible. If you run, you can't catch up with others." Xiao Ming can't be heartless at all.

Because the sea is much more dangerous than the state of Dayu. He is a prince in Dayu, and some people give him face.

When it comes to the sea, who cares that this is the warship of the seventh Prince of the state of Dayu. When Yue Yun and others can come back, he will have to burn incense.

But even so, he had to do it.

Because in the era of great navigation, whoever controls the maritime hegemony will control the trade routes.

Today, the Silk Road on the road is cut off by the Ottoman Empire, and there are barbarians in the north. It is impossible for him to trade through this road, and he may still use his own advantages to monopolize the trade routes in East and Southeast Asia.

As long as there are dumping places for goods, Qingzhou's industry can thrive.

Three people all say so, Yue Yun more treasure their own Galen ship, he said: "yes, your highness, Yue Yun remember."

All the gunboats were on board, and all the three galleons were ready. At this time, Xiao Ming and Yue Yun boarded the flagship Qingzhou of the galleons.

This time, he will follow Yue Yun along the Xiaoqing River to the sea mouth of Bohai Bay, and then arrive at Dengzhou from the sea mouth, so that Yue Yun can practice his navigation knowledge through this route.

Zhang Liang immediately gets on the boat. Xiaoqinghe shipbuilding workshop will be managed by his son, and he will go to Dengzhou to take charge of Dengzhou shipbuilding workshop.

After all, Xiao Ming's naval base was selected in Weihaiwei, Southeast of Dengzhou.

Many people must be familiar with this place, because the battle of Weihaiwei was part of the Sino Japanese naval battle of 1894-1895.

Weihaiwei is close to the Yellow Sea in the north and Southeast, opposite to Liaodong Peninsula in the north, and across the sea from Korean Peninsula and Japanese archipelago in the East and Southeast.

Once he had a firm foothold in Weihaiwei, Xiao Ming would have seized the route of South Korea and Japan, and could face the Ryukyu Islands.

At the same time, the location of the naval base, as the name suggests, is also a plot of personal feelings. Now he wants to find back the dignity he once lost here.

"Sail."

Galen ship, a loud call to remember, the mast of the sail like a waterfall down.

Then the wind blew up the canvas, and the first mate put on immediately took the helm to control the Galen ship to leave the Wharf under the push of the wind.

And the Galen ship behind followed the flagship to pull out the anchor and set sail.

The Xiaoqing River is wide. The Galen boat goes all the way down the lake to the East. Within a day, it arrives at the mouth of the sea. When it sees the wide sea, Xiao Ming says, "let's start the drill."

Yue Yun nodded and yelled, "start the drill."

At this time, put on the flagman immediately stood at the stern of Galen, to the Galen behind the ship made a flag.

After the Galen saw the flag, the captain immediately began to command the navigator to measure the dimensions and calculate his position.On the Qingzhou ship, Yue Yun takes out the quadrant and records the position of the stick's reflection on the quadrant. He immediately sets up a formula to calculate it and takes out the form Xiao Ming gave him.

Because when he was in Qingzhou, he had already recorded once, and this time he calculated again, and he quickly got his position, "Your Highness, we are at 53 degrees north latitude, 97 nautical miles away from Qingzhou."

Half an hour later, Yue Yun told Xiao Ming the data he got.

Xiao Ming nodded. When he was in Qingzhou, the latitude of Yue Yun's computing was 49 degrees north latitude. Now they are going a long way obliquely.

Then he calculated again, which is almost the same as Yue Yun's.

He is satisfied with this result. After all, in this era, instruments have errors, and it is impossible to be so accurate. It is amazing to be able to roughly get his own position.

When Yue Yun left, Xiao Ming also gave him the latitude and longitude map he had drawn. According to the map, Yue Yun could basically get his current geographical location.

After measuring longitude and latitude, Xiao Ming said, "speed and time."

The crew of the ship at this time to act immediately, when a sailor quickly opened the hourglass.

This is what the glass workshop recently handed over. The sand flowed out and began to count. At the same time, another sailor threw into the sea a triangular board tied with a rope, holding a hemp rope wrapped in a spindle in one hand.

At this time, the triangle board floated on the sea. As the ship sailed forward, the rope tied at an equal distance was loosened from the spindle and passed through the Seamen's palm.

"Stop!" After waiting for a while, Yue Yun suddenly called, and one of the crew stopped the hourglass immediately.

The seaman in charge of the rope counted the knots and reported a number. Yue Yun then calculated the number of knots passing through his palm during the hourglass time.

After calculation, Yue Yun said, "Your Highness, the current speed is eight knots."
