"That's okay, it's better to choose a day than to hit the day, today I will teach the children a lesson, what are you talking about? Shall I tell you about the basic principles of electromagnetism? Luo Jian thought about it, and simply gave a lesson to the children, which can be regarded as a start for future electromagnetic research.

"The principle of electromagnetism? Okay, the old man has a day off today, and I'm going to listen to it too, by the way, let them all come, it's a new thing. Song Yingxing said excitedly.

"Xinghua, you want to teach everyone? Anyway, I'm going to spend it here today, so I'll listen to it too. Shi Kefa also rushed over to join in the fun.

For a while, the news that the governor was going to give a lesson to everyone spread quickly in the Guazhou factory.

"Xinghua, let's go to the workshop where the steam engine was built, the steam engine built there has just been shipped away, and now it is empty, and there is no other place that big." Song Yingxing said as he walked.

"Okay, just go to Song Laoding, the key is to have a blackboard and chalk." Luo Jian didn't care about the location.

What Luo Jian didn't expect was that the huge workshop was full of people, Liu Jun and Zhu Cihuan were still competing for a seat in the first row, and Liu Cui'e and Li Yue were also sitting in the back with their notebooks.

Yangzhou is now the most indispensable is the blackboard, Song Yingxing usually gives lectures to the students is also the blackboard, a big blackboard in front of the workshop has been erected, Luo Jian walked to the front of the blackboard in a few steps.

"Hello everyone, Mr. Song asked me to give you a lesson today, I thought about it, what can I tell you? Song Lao is already very expert in mechanical knowledge, everyone from Song Lao first emptied all the goods in his stomach, temporarily enough, I hope you will not relax in the future in-depth research. ”

"What I want to tell you today is a brand new knowledge, time is limited, I can't tell you very deeply, I can only start, I hope you will strengthen the study of this knowledge in the future, this knowledge is learned, the study is deep, and the future will be of great use."

As Luo Jian spoke, he wrote two big characters "electricity" and "magnetism" on the blackboard, and marked traditional Chinese characters next to him after writing.

Luo Jian started with some common sense of lightning, and then talked about the compass, a class lasted for three hours, and almost everyone was fascinated by it, even Shi Kefa listened to it without blinking.

"Today I can only tell you about this, the next some knowledge Xiao Liu will tell you one after another, I will give you a start today, lead the way, I hope that with the joint efforts of everyone, our'upstairs and downstairs, electric light and telephone' can be realized as soon as possible." Luo Jian ended his lecture.

"I said Xiao Zhuzi, I said a long time ago that Uncle Luo is omnipotent, are you convinced?" As soon as class ended, I heard Liu Jun shouting to Zhu Cihuan.

"I said Xiaojunzi, don't make any noise, I still haven't figured out what Uncle Luo said just now, I have to ask Uncle Luo." Zhu Cihuan ignored Liu Jun, squeezed out of the crowd, ran to Luo Jian's side, and held up the notebook in his hand to find Luo Jian and ask questions.

After Zhu Cihuan finished asking and ran away, Shi Kefa said beside him: "Xinghua, I really envy your education, when we can educate our descendants like you." ”

"Alas, Brother Xian, that's really bitter!" Luo Jian said with a smile.

"You see, this kid is now obsessed with technology, and I really don't know if it's a good thing or a bad thing." Shi Kefa pointed to Zhu Cihuan's back and said.

"How is this a bad thing? Our country has one less useless emperor and one more scientist, it's a beautiful thing to think about, it's too late for me to be happy, why do you still sigh, Brother Xian? Luo Jian said.

"Xinghua, it's so good, you have opened a door for us today, and one day someone from these children will become the scientists you said." Song Yingxing sorted out his notes and walked over to say.

"It's noon, where can we get something to eat?" Luo Jian turned around and asked Shi Kefa.

"Okay, I won't be able to catch up with the meal when I go back."

"Let's go, come to me, I still have a small stove there, I don't usually use it often, today Xinghua has worked hard, it can be regarded as a reward for you, use it." Song Yingxing said happily.

Luo Jian and Shi Kefa walked to Song Yingxing's small courtyard, the small courtyard was built very chic, the few flowers and plants in the courtyard were very luxuriant, and a few peach trees in the courtyard were blooming, giving people a feeling of spring.

"Let's move the table under the peach tree, it's so comfortable here." Luo Jian said.

A small table was moved under the peach tree, and Song Yingxing asked people to carry out a few small chairs from the house and sit under the peach tree, basking in the warm spring sun, which made people feel comfortable from the bottom of their hearts.

"Xinghua, I heard that you are playing Go well, let's talk about a game? Since I arrived in Yangzhou, I haven't had time to touch it, so I just relax today, anyway, it will take a while for lunch to be ready. Song Yingxing was very interested today, and as he spoke, he asked people to move out the chessboard and chess pieces.

"Xinghua, you can also play Go?" Shi Kefa looked at Luo Jian in surprise.

"It's still amazing, but this kid doesn't follow the rules when he plays chess, and he takes out all the seats when he plays chess with others." Song Yingxing said with a smile.

"Who has such a long mouth? Everything about Xuzhou is known here? "Luo Jian has been here for a year, and he has only played two games in Xuzhou with Yan Yingyuan and Gao Xiaozhang.

"Let's not talk about the rules today, let's take off the seats, and everyone can do whatever they want." Song Yingxing picked up a white piece and slapped it on Tianyuan (white chess goes first in ancient chess).

"Rules are used to break, this sub-rule seriously restricts the change of Go, I heard that the level of Go in Japan is developing rapidly, and Go without a seat is more about the overall situation, although this thing is entertainment, but we can't lag behind the Japanese." Luo Jian picked up a sunspot and went down to the position of the small target.

Both of them fell quickly, Shi Kefa couldn't see it on the side, and Song Yingxing, who was nearly sixty years old, was obviously not as good as Luo Jian's calculation power, and soon a piece of chess fell into a desperate situation.

"I said Xinghua, seeing that you are usually a person who can win people, why are you so fierce on the chessboard? The trick can't leave the back of the old man's head. Song Yingxing was muttering while playing, and Shi Kefa was secretly amused when he heard it.

"Here! Here! Shi Kefa saw that Song Yingxing's son fell, and the big dragon was about to die, so he hurriedly pointed to the chessboard and said.

"I said what are you talking about, Inspector, bullying the old man is dazzling, I can see it clearly." Song Yingxing in front of the chessboard was very funny, saying in his mouth, but the hand holding the chess piece moved to the position of Shi Kefa's finger.

Shi Kefa looked at it and laughed.

Shi Kefa's laughter did not fall, and the guards at the gate reported that someone was coming, and Shi Kefa hurriedly let people in, and saw that it was the general on duty at the mouth of the Yangtze River sent by the sailors.

Since the merchant fleet went to sea for nearly two months last month, Shi Kefa has been counting the days every day, and he has to go to Luo Jian every day to ask again, Luo Jian really can't stand it, so he asked the sailor to send a ship to the Yangtze River estuary on duty, so that they can report back immediately if there is a situation.

The sailor ship on duty was dispatched for nearly a month, and there has been no news of it, which has deepened Shi Kefa's worries.

"Report to the Metropolitan Governor and Inspector that a large number of ships have entered the Yangtze River at the mouth of the Yangtze River, and the Navy Division has sent people to inspect it."

"What?" When Luo Jian heard this, he stood up suddenly, and Shi Kefa almost didn't fall off the chair.

"What's the panic? The sky can't fall, I said you can't play this chess? Song Yingxing didn't understand, and still stared at the chessboard and said.

"Is the fleet back?" Luo Jian asked.

"What do you say? The flotilla is back? Song Yingxing stood up suddenly, but because he got up too violently, he was dazzled to the side, and Luo Jian hurriedly stepped forward to support him.

"What are you waiting for? Let's hurry up and check it out, shall we? Song Yingxing said anxiously after standing firm.

"Old Song, the fleet has just entered the mouth of the Yangtze River, and it is still early to arrive in Guazhou, if it is our fleet, it is estimated that it will not arrive until the morning after tomorrow, and I will come back on two horses to report the news." The general of the water division said.

"Send someone to inquire again to determine if it's our fleet." Shi Kefa gritted his teeth and said.

"Hey, didn't I say your steamship was fast? Just check it out. Song Yingxing, who calmed down, said.

"That's right! Why did I forget about this stubble, Xinghua, hurry up and eat, let's go and have a look after dinner, and let them fill up the coal on the ship. "Shi Kefa couldn't wait.

"I said Brother Xian, if it's our fleet, then it can't run, what's the hurry?" Luo Jian was not in a hurry at this time, it could not be other fleets coming at this time, it could only be a merchant ship returning from a long voyage.

"No, I said Song Lao, why are you so late in serving this meal? Just let them stir-fry a few dishes, just serve them quickly and fill their stomachs. Shi Kefa didn't care about it, he had to go and take a look.

"Okay, Brother Xian, how about I accompany you?" Luo Jian said helplessly.

Song Yingxing was also in a hurry, and kept urging to hurry up the meal, serving two or three dishes, the three of them picked up the rice bowl and opened it, and filled their stomachs after dividing five by two, and the three of them rushed to the Guazhou wharf together.

Shi Kefa, who got on the steamship, urged the ship to drive the ship as fast as possible, and the steamship that went down the water was very fast, and went to the mouth of the Yangtze River with a puff of smoke.

By the time the steamship arrived at Nantong, the shadow of the fleet ahead could already be faintly seen, but it soon became dark.

The steamship picked up the gas lamp, and the speed was reduced.

He saw that Song Lao was always lighting torches and lanterns in the evening, and the light was too dim, for fear of damaging everyone's eyes, so he specially made more than a dozen.

The steamship was getting closer and closer to the fleet in front of it, Shi Kefa pressed his chest with his hand, and even Luo Jian was a little nervous.

"The ship in front quickly stopped and avoided, this is the Yangzhou Navy ship." There was a shouting voice from the big boat in front of them, Shi Kefa and Song Yingxing didn't hear it clearly for a while, and hurriedly asked Luo Jian what he was shouting.

"It's a ship of our navy." Luo Jian said with a smile, he told Zheng Chenggong that our warships at sea are called navy, but he didn't expect him to regard this merchant fleet as a navy.

"Ships of the Navy?" Shi Kefa didn't understand for a while, and asked suspiciously.

"It's our returning fleet!" Luo Jian shouted loudly.

"Shout, the Governor is here!" Scofa said to the sailors on the ship.

Five or six sailors were on the bow of the steamer, and shouted in unison to the big ship: "Welcome back, the Governor is here to greet you!" ”

After shouting a few times, I heard bursts of cheers from the big boat opposite, and after a while, a small boat was lowered next to the big boat, and the small boat quickly rowed next to the steamboat, and it was Lu Wei and Zheng Chenggong standing on it.
