Chapter 153 Set sail
As for the harm to production workers, it can be minimized by using labor protection products, such as fully wrapping production workers, adding activated carbon to the breathing area to absorb mercury vapor, etc.

In addition to these, we can also study closed heating appliances to cool and reuse mercury vapor, and seal the environment to prevent mercury vapor from coming into contact with production personnel to reduce harm, etc.

It is better to leave the harm to Xinghan League than to leave it to consumers who buy mirrors.

If the harm is left to Xinghan League, it can be minimized through the development of technology. If it is left to consumers, then consumers will have no choice but not to use it.

After coming out of the cabin where the mirrors were stored, Liu Xinqi went around a few more cabins and checked the goods for this trade. These glass products were all well preserved.

Back on the deck, I happened to see a guide boarding the ship.

"How many people are still here?"

Liu Xinqi asked the crew member who was assisting the guide to board the ship.

"This is the last one, everyone is here."

"Hello, leader, I'm sorry I'm late."

After the crew member answered, the guide heard that he was the last one and immediately apologized to Liu Xinqi.

"It's not late. It's not yet dawn. Go to your cabin."

Watching the guide enter the cabin, Liu Xinqi came to the wheelhouse, and Li Cang was indeed here.

"Let's set off as soon as dawn." Li Cang heard someone coming in, turned around and saw it was Liu Xinqi, and reported directly.

"it is good."

After staying in the wheelhouse for a while and chatting with Li Cang for a while, Liu Xinqi got up again and went to the top deck. At this time, the sky was already bright, the weather was very good, and the sky was clear.Liu Xinqi simply stood on the deck and watched the sunrise at Penglai Port.

Xinghan League has passed the most difficult moment and can finally develop steadily. Liu Xinqi's pressure is also much less. Now he can calm down and watch the sunrise. Different mentality can feel a different kind of beauty.

"Yang Fan!!"

The officer's order came from below, and then the rigmaster repeated it.

"Yang Fan!!"

Then came the neat chanting of the sail-raiser.

"Hey! Ya! Hey! Ya!"

The heavy hard sail quickly rose with the help of the pulley, and the hull began to swing with the sea breeze.

"Raise anchor!"

"Raise anchor!"

came the sound of orders and repeated orders.

The anchor at the stern of the ship was slowly rolled up.

The cables tied to the shore were also untied and thrown on board.

"set sail!"

Ten sailors stood against the side of the ship on one side of the pier, each holding an oar with one end on the shore, and together they pushed the ship away from the shore.

Then the ship slowly adjusted its direction. The length of the sail cable began to adjust the angle of the sail according to the command of the captain. The ship began to gradually accelerate and headed towards the open sea. "Your reserve talent training plan is very good. Each ship will train more than two sets of management, one for each, which makes me feel much more relaxed." Li Cang also came to the deck and stood next to Liu Xinqi and said.

Because it is difficult to train seamen and it takes longer to train technical personnel on ships, Liu Xinqi asked the navy to equip each ship with two sets of personnel during the last reorganization.

For example, a two thousand stone sand ship can operate normally with a crew of 50 people. Xinghan League is equipped with 100 people.

On the one hand, this speeds up the training of technical naval officers and soldiers.

On the other hand, after capturing enemy ships during war, you can directly control local ships to fight or return.

Finally, if the navy expands in the future, the manpower will be ready.

"I used to have to command both the fleet and the ship. Now the two officers on my Qizhou can basically take charge of their own duties. I only need to concentrate on commanding the fleet, which makes it a lot easier."

After Li Cang finished speaking, Liu Xinqi replied:

"I let you serve as captains concurrently before, firstly because of the lack of talents. Secondly, because there are few trustworthy people. In the future, you will be independent. You will no longer be part-time captains, and you will concentrate on commanding the fleet to fight and improve combat effectiveness."

"That said, I will cherish the opportunity to be the captain of this trade voyage. I won't be able to be a captain in the future."

Li Cang joked.

……

The flagships of the two fleets sailed to Baishi Bend an hour later, joined the other ships in Baishi Bend, and began to form a formation.

The first fleet, led by the flagship Dengzhou, formed a long snake formation and headed east.

The third fleet was led by the flagship Qizhou and followed the first fleet in a long snake formation.

The two fleets sailed to the waters outside Wendeng County before dark, stopped at sea for one night, and began to go their separate ways the next day. The first fleet sailed south, and the third fleet continued to sail east.

After sailing out to sea for half a day, the coastline of the Shandong Peninsula was no longer visible. Liu Xinqi came to the wheelhouse of the Qizhou and saw Li Cang using the sling method to measure the direction.

Scholar Shen Kuo said in his "Mengxi Bi Tan" that "the Fang family uses magnets to sharpen their needles, and they can guide."

This is talking about the Luxuan method compass.

In the State of Zhao, there were three types of "compasses" commonly used to measure the direction of ships at sea: the thread-suspended method, the water-floating method, and the compass. These three methods were all recorded in the "Wu Jing Zong Yao" and were therefore widely spread.

The thread suspension method is to use thin silk as a suspension thread, use wax to stick the thread to the middle of the magnetic needle, and hang it on a wooden frame.When the magnetic needle is at rest, its ends will point north and south.The water float method is to pass a magnetized iron needle through rushes to make it float on the water surface. The magnetic needle can rotate on the water surface and indicate the direction.The guide fish puts a magnetized fish-shaped iron piece in the water to indicate the north, south, east, and west.

The latter two require a large bowl to be filled with water. On a ship, when the ship swings, the magnetic needle or fish-shaped iron piece can easily touch the wall of the bowl, affecting the measurement.The strand hanging method can be used normally if it is limited by strings, and after it is made, it can be used repeatedly.

Liu Xinqi knows that using a compass may not be accurate because the earth's north and south poles and the geomagnetic poles do not coincide, and there is a geomagnetic declination.Therefore, the south pointed out by the compass is often eastward, which requires the captain or helmsman to adjust based on experience.

As an inland person in his previous life, Liu Xinqi had never engaged in any work related to shipping, nor had he come into contact with anyone who worked in shipping. He browsed the Internet and read books every day, and had never seen detailed knowledge on how to identify the direction of a ship at sea.

I only know some terms, such as navigation sextant, star positioning, etc., but I have no clear idea of ​​the specific principles of these things, how to make them, and how to operate them.

Therefore, Liu Xinqi has no advantage at all in navigation compared with the ancients.

At least the old captain who often travels by sea can still look at the stars and the sun to identify the direction. Liu Xinqi can only look at the sun to roughly identify the direction and the stars. Except for the Big Dipper, he doesn't recognize any others.

"Is this measured direction accurate?" Liu Xinqi asked.
