Running around the College of Liberal Arts and the Royal Mansion every day, another New Year passed quickly. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

On the fifth day of the first lunar month, Qingzhou's government institutions basically resumed normal operation.

The people can enjoy the New Year until the fifteenth day of the middle month, but Xiao Ming can't indulge in it and think of danger in peace, which is what he reminds himself all the time.

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

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

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

In the Xiaoqinghe shipyard, Chen Qi slowly breathed a sigh of relief as he watched the last naval gun being hoisted onto the ship.

During the Chinese New Year, the military workshop was not idle, and all the craftsmen worked day and night to finally deliver all 150 naval guns.

Since Xiao Ming went to Cangzhou, this naval gun was produced for a total of three months, with an average of fifty guns per month.

Similar to the city defense cannon at the head of the city, the naval gun is a heavy gun, which belongs to a 32-pounder gun in Qingzhou's artillery standard, and 60% of the shells on board this time are normal solid shells, while the remaining 40% are grape shells.

According to Xiao Ming, grapeshots are actually naval shells, which are specially used to bombard opposing ships.

Zhang Liang looked at the Galen ship and the guns on the ship and said to Yue Yun: "Yue Yun, you have to be careful when you go out this time, this Galen ship cost 300,000 taels of silver to build, this is not a ship, this is silver." ”

Chen Qi added: "That's not all, all the naval guns on board this time are eight or nine thousand catties, and the cost of each gun is around five thousand taels of silver, and these one hundred and fifty guns are seven hundred and fifty thousand taels of silver." ”

As soon as the two of them said this, Yue Yun's head suddenly sweated, and he looked at Xiao Ming: "Your Highness, look at the two of them, how can I drive the Galen ship out to sea." ”

"What they said is also true, these three Galen ships are more than one million taels of silver, Yue Yun, you can't come nonsense when you get to sea, remember your mission, not to fight, but to explore, although our ship is small, but it is flexible and flexible, if you run, basically others can't catch up." It is impossible for Xiao Ming not to feel distressed at all.

Because this sea is much more dangerous than the Great Chongqing Kingdom, he is a prince in the Great Chongqing Kingdom, and some people give him face.

This is at sea, who cares that this is the warship of the Seven Princes of the Great Yu Kingdom, when Yue Yun and the others can come back, he will have to burn high incense.

But despite this, he had to do it.

Because in the Age of Discovery, whoever mastered the hegemony of the seas mastered the trade routes.

Now that the Silk Road has been 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 advantages to monopolize the trade routes of East Asia and Southeast Asia by sea.

As long as there is a dumping ground for commodities, Qingzhou's industry can flourish.

The three of them all said this, Yue Yun treasured his Galen ship more and more, and he said, "Yes, Your Highness, Yue Yun remembers. ”

All the gunboats were on board, and everything was ready for the three Galen ships, and at this time, Xiao Ming and Yue Yun boarded the Qingzhou, the flagship of the Galen ship.

This time, he was going to follow Yue Yun along the Xiaoqing River to the mouth of the Bohai Bay, and then arrive in Dengzhou from the mouth of the sea, so that Yue Yun could practice the navigation knowledge he had mastered through this route.

Zhang Liang then got on the boat, and the Xiaoqinghe shipyard would be managed by his son, and he would go to Dengzhou to take charge of the Dengzhou shipyard.

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 First Sino-Japanese Naval Battle.

Weihaiwei is bordered by the Yellow Sea on three sides in the north and southeast, the Liaodong Peninsula in the north, and the Korean Peninsula and the Japanese archipelago across the sea in the east and southeast, and the geographical location is very dangerous.

Once he gained a firm foothold in Weihaiwei, Xiao Ming would be able to choke the southward route of Goryeo and the Wa Kingdom, and he would be able to face the Ryukyu Islands.

At the same time, the location of the naval base in this place, as the name suggests, is also for a personal mood plot, and the dignity that was once lost here is now to be regained.

"Fly the sails."

On Galen's ship, a loud trumpet was remembered, and the sails on the mast poured down like a waterfall.

Then the wind blew the canvas up, and the first mate, who put it on, immediately took the helm and controlled the Galen ship to change out of the dock under the impetus of the wind.

And the Galen ship in the back followed closely behind the flagship to pull anchor.

The water surface of the Xiaoqing River is wide, and the Galen boat went down the lake all the way to the east, and arrived at the mouth of the sea in less than a day, and saw the wide ocean, at this time Xiao Ming said: "Let's start the drill." ”

Yue Yun nodded and shouted, "Start the drill." ”

At this time, the flagbearer immediately stood at the stern of the Galen ship and waved the flag to the Galen ship behind.

When the Galen ship behind saw the flag, the captain immediately began to instruct the navigator to measure the dimensions and calculate his position.

On the Qingzhou, Yue Yun took out the quadrant and recorded the position of the wooden stick's reflection on the quadrant, he immediately set the formula to calculate, and at the same time took out the form that Xiao Ming gave him.

Because he had already recorded it once when he was in Qingzhou, this time he quickly came up with his location by calculating it again, "Your Highness, we are at fifty-three degrees north latitude, and we have walked ninety-seven nautical miles from Qingzhou. ”

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

Xiao Ming nodded, when he was in Qingzhou, Yue Yunyun's latitude was forty-nine degrees north latitude, and now they are walking diagonally for a while.

Then he calculated it again, which was basically similar to Yue Yun's calculation.

He was already satisfied with this result, after all, in this era, instruments are all errors, it is impossible to be so accurate, and it is already remarkable to be able to roughly derive his position.

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

After measuring the latitude and longitude, Xiao Ming said: "Speed and time. ”

The ship's crew immediately sprang into action at this time, when a seafarer hurriedly opened the hourglass.

It was the most recent handover of the glassworks, and the sand flowed out and the timer began, while another seafarer threw into the sea a triangular plank tied with a rope, holding a hemp rope wrapped around a spindle in one hand.

At this time, the triangular plank floated on the surface of the sea, and as the ship sailed forward, the rope tied in knots at equal distances continued to loosen from the spindle and pass through the seafarer's palm.

"Stop!" After waiting for a while, Yue Yun suddenly screamed, and a crew member immediately stopped the hourglass.

The seaman in charge of the rope counted the knots and reported a number, and Yue Yun counted the number of knots that passed through his palm during the hourglass time.

After calculating for a while, Yue Yun said, "Your Highness, the current speed is eight knots. ”
