There are also many ships sailing on the Yangtze River waterway, and the appearance of the "Wei Qing" has attracted all the people on board to come out to watch and point fingers at the "Wei Qing" one after another.

As the mainsail was raised, the "Wei Qing" continued to speed faster and faster, overtaking the other ships in the channel, even though the steam engine had stopped transmitting power.

Luo Jian stood on the main deck, watched the "Wei Qing" go down the Yangtze River, and estimated the speed, about more than ten knots.

Zheng Chenggong ran to Luo Jian's side, raised his hand and saluted and said: "Governor, our warship has finally been launched, the last time we encountered the Dutch fleet, our 'Wei Qing' is here, it is estimated that they don't even dare to approach." ”

"Hehe, the 'Wei Qing' is our first warship, there will be more and more advanced warships launched in the future, you have to think more about the combat methods of these large warships." Luo Jian said with a smile.

"Governor, I will, we will go to sea again after this trial voyage, right?" Zheng Chenggong asked excitedly.

"Yes, the big guy built it, isn't it just to go to sea?" Luo Jian said with a smile.

"I said Damu, what are you going to do if the 'Wei Qing' goes to the South Seas and meets the Fujian Navy?" Liu Lan walked over and asked, "Little Tail" still following behind.

"I've told the Metropolitan Governor a long time ago, if they don't provoke us, they will be fine, and if they take the initiative to provoke, I won't be polite." Zheng Chenggong said resolutely.

"Let's go, let's take a closer look at our 'Wei Qing'." Luo Jian saw that Zheng Chenggong was fine at the moment, so he asked him to take a good visit to the "Wei Qing".

Zheng Chenggong led Luo Jian and others from the main deck, and everyone kept introducing the configuration of the "Wei Qing" to everyone.

Luo Jian has seen the physical model of the "Sea King", the "Sea King" is extremely gorgeously decorated, and the visual effect is indeed much better than the "Wei Qing".

There is no redundant design on the "Wei Qing", every part is useful, and its decoration is also extremely simple and simple.

But the long barrel of the sailcloth-wrapped cannon on the side of the "Wei Qing" reminds people that this is not a pleasure boat for people to play, but a warship armed to the teeth.

Luo Jian and others came to the main wheelhouse, and a huge glass was installed in front of the main wheelhouse, which gave the "Wei Qing" some modern atmosphere.

The first mate on the ship was personally at the helm, and the extremely fast speed of the "Wei Qing" made him very careful, and under his control, the "Wei Qing" was always sailing in the middle of the Yangtze River channel.

Luo Jian saw the sextant in the main wheelhouse, the sextant is an instrument used to measure the longitude and latitude of the ship at sea, the sextant really appeared in history in 1732, and Yangzhou first used the sextant nearly 90 years earlier than the British.

"Governor, the sextant was already used on our last voyage, don't look at its smallness, it's really too useful, with it, we basically don't have to worry about getting lost at sea anymore." Zheng Chenggong explained beside him.

Luo Jian saw a large nautical chart on the wall of the main wheelhouse, obviously this nautical chart was not a product of this era, but Xiao Liu made it from the computer, and its accuracy was of course beyond doubt.

Luo Jian picked up the sextant and looked at it carefully, this sextant was very well-made, and the scale division on it was very even, obviously Guazhou's technology had made great progress.

Walking out of the main wheelhouse, Luo Jian came to the side of the artillery on the side of the "Wei Qing", these guns are not like the "King of the Sea" to open a window to remove the barrel, the range of the artillery is very open, Luo Jian feels that there is no difference with the artillery of the First World War.

"Da Mu, sea voyage, how do you add green vegetables?" Luo Jian asked.

"Governor, our voyage time is not too long, and the vegetables carried on the ship are usually enough to eat." Zheng Chenggong said.

"Haha, Brother Luo, speaking of which, I thought of another channel to make money." Liu Lan followed behind and heard the conversation between the two of them, and laughed as she followed.

"You mean to get the cans out?" Luo Jian asked with a smile.

"I said Brother Luo, can you pretend not to know? It also gives me a sense of accomplishment. Liu Lan said with a wrinkled nose, hearing Luo Jian laugh.

"It must be made out, our fleet will sail to the ocean in the future, and if there is canned food to replenish it, then there will be no problem." Luo Jian said.

Zheng Chenggong listened to the conversation between the two like a cloud, and only looked at the two with puzzled eyes, and Luo Jian told Zheng Chenggong in detail about the knowledge that the human body needs to supplement vitamins.

"Governor Xie Dadu, I heard my father say before that the sailors on the ship often die of strange diseases, and the original reason is here."

Zheng Chenggong listened to it and felt that he had gained a lot of knowledge.

Everyone walked and talked all the way, and slowly walked to the second floor of the "Wei Qing", the second floor looked a lot more crowded than the first floor, the sailors mainly lived on this floor, and the buildings on this floor were also the most.

Luo Jian walked into the cabin where the sailors lived, and saw that it was still very crowded, frowning and shaking his head.

"The Grand Governor, sea voyages are like this, you can't be spacious." Zheng Chenggong explained beside him.

"Damu, the fleet is sailing, and it is not easy to replenish fresh water, but you must find a way to maintain the hygiene on the ship and prevent the epidemic of diseases. Luo Jian said.

"By the way, Damu, is there a military doctor on the 'Wei Qing'?" Luo Jian asked.

"Governor, yes, there are two military doctors." Zheng Chenggong replied.

"Two? It's too little, there are six hundred people on this ship, right? At least six people should be equipped, you write down this, and we will arrange it when we go back to the trial voyage. Luo Jian confessed.

A general behind Zheng Chenggong held a small notebook in his hand and kept making notes, Zheng Chenggong turned around and asked, "Have you written down what the Metropolitan Governor said?" ”

Seeing the general holding up the notebook and nodding, Zheng Chenggong was relieved.

"My words are not golden words, don't remember everything, just write down the useful ones." Luo Jian said with a smile.

"The words of the Metropolitan Governor are useful, and we must all remember them." Zheng Chenggong said very seriously.

"What do you call this, I'm also a human being, don't do this, you have to point out the wrong things directly, if I treat the wrong thing as the right thing to do, then something big will happen." Luo Jian heard Zheng Chenggong say this, and also said to him seriously.

"I think Da Mu is a little too much, some of the things that the Metropolitan Governor said are a summary of many people's experience, you just write down these things, you just listen to some words, don't start the personality cult from you." Liu Lan also said beside her, and Luo Jian nodded yes.

After listening to the words of the two, Zheng Chenggong scratched his head, and he couldn't react.

"Governor, look, we're going to sea." A sailor pointed to the outside of the ship and said.

Luo Jian saw that the sky had darkened, and the "Wei Qing" had already arrived at the mouth of the sea.

According to the original plan, the "Wei Qing" left the Yangtze River to go north, and returned to Haizhou.

"Does the Governor have any other instructions?" Zheng Chenggong asked.

"Just follow the original plan." Luo Jian replied.

Dinner was eaten in the officer's canteen on the ship, three dishes and one soup were not bad, Luo Jian asked the soldiers if they were all the same, and when he heard the affirmative answer, Luo Jian sat down to eat.

Zhu Yujiao was a little listless, the excitement when she first got on the ship was gone, and the rest of the long time on the ship was just boredom.

It was already completely dark, and Luo Jian, Zheng Chenggong, Fang Yizhi and others were sitting on small stools and chatting on the deck.

The "Wei Qing" did not stop, and continued to sail along the coastline, and Luo Jian estimated that it was about twenty or thirty kilometers from the coast.

The sea breeze in April was still a little cold on her body, Liu Lan held Zhu Yujiao in her arms, seeing that she was very bored, holding her body, Liu Lan said softly: "Yu Jiao, are you bored?" I'll sing you a song. ”

Hearing that Liu Lan was going to sing, Zhu Yujiao suddenly came to her senses, sat up straight and said, "Sister, sing quickly, my sister must sing well." ”

"The night of the military port is quiet, the waves gently shake the battleship, and the young sailors rest their heads on the waves, and smile happily in their sleep..."

As Liu Lan's soft singing sounded, the people on the deck stopped chatting and quietly listened to Liu Lan singing, there were already many sailors around the deck, many of them had sailed with Zheng Chenggong, listening to the singing, several sailors shed tears.

Zheng Chenggong listened very carefully, silently remembering the lyrics and tunes in his heart, and when Liu Lan finished singing, Zheng Chenggong was still immersed in the beautiful melody.

"Sister, your song is specially sung for sailors, it's really good." Zhu Yujiao snorted as she spoke.

"You don't have to memorize, tomorrow I will write you the lyrics and the score, and you have to let everyone learn it." Liu Lan saw that Zheng Chenggong was still silently remembering, knew his intentions, and said to him.

"Sister, go to bed early, let's get up tomorrow morning to watch the sunrise." After chatting for a while, it was getting late, and Liu Lan said to Zhu Yujiao.

Luo Jian woke up early in the morning and went directly to the deck, the sky was already bright, the morning glow in the distance was gradually brightening, and the sun was about to come out.

Liu Lan and Zhu Yujiao were already on the deck, and when they saw Luo Jian coming, they both greeted him with a smile.

After a while, Zheng Chenggong also rushed over, saluted and then said: "Metropolitan Governor, the 'Wei Qing' is going to conduct the maximum speed test today, do you have anything to explain to the Metropolitan Governor?" ”

"Just follow your plan and leave me alone." Luo Jian said.

After breakfast, the "Wei Qing" put down the boat, and the boat measured the distance as it moved forward, and the boat stopped about five kilometers in front of the "Wei Qing."

At this time, the main sail and the two auxiliary sails on the "Wei Qing" had all been raised, and the speed was obviously much faster, and with Zheng Chenggong's order, the four steam engines also output all the power, and everyone felt that the hull of the ship was shaking, and the speed of the "Wei Qing" became faster and faster.

The "Wei Qing" soon arrived near the boat, Zheng Chenggong had already organized a group of people to calculate the speed of the "Wei Qing", and Luo Jian was also counting the time with his watch.

After Luo Jian's conversion, the final result was about eighteen knots, which was far beyond the most advanced sailing warships of this era.

Next, the "Wei Qing" tested the speed of sails only and steam only, which were about 11 knots and 13 knots respectively, which means that the speed of steam drive alone is faster than that of ships with soft sails.

Zheng Chenggong was obviously very satisfied with this speed, so that the "Wei Qing" not only had extremely strong firepower, but also had extremely fast speed, which could both hit and run.

After testing the speed, the "Wei Qing" tested the performance of the gun, and the sixteen guns on one side fired one after another, which did not have much impact on the hull, if all the salvos were fired, the hull would still have a relatively large shaking, Luo Jian knew that for the ship with wood as the main body, this was inevitable, and its own weight was still too light.
