After the teaching, Zhou Xian asked the craftsmen to return to the workshop to make industrial mother beds.

Then Zhou Xian appointed the remaining students, "Luo Yangping is temporarily the director of the steel plant, responsible for everything. ”

"Thank you for the promotion, I will work hard and manage the steel mill well." Luo Yangping said excitedly.

After walking out of the arsenal, Zhou Xian saw that it was still early, so he walked to the chemical factory to see what Chen Lufeng was doing recently.

When Zhou Xian came to the chemical factory, he found that Chen Lufeng was making phosphate fertilizer with a group of workers, and when he saw Zhou Xian coming, Chen Lufeng came over with a smile.

"How come the president has time to come to our chemical plant?" Chen Lufeng asked with a smile.

"It's been a long time since I've seen Director Chen, so I'm here to see you." Zhou Xian said with a smile.

"Thank you for your concern, the president has something to explain."

"I'm here to ask you to make a few things."

"I wonder what you're making?" Chen Lufeng asked curiously.

"I found that it is very troublesome for people to light a fire when they are cooking on a fire, so I want you to make a match to start a fire." Zhou Xian said.

"What is a match? Is it a fire fold? ”

Chen Lufeng was even more curious and asked.

"A match is a very convenient thing to light a fire, as long as you take out a match and gently swipe it on the white phosphorus surface, it can be ignited." Zhou Xian explained.

"President, this is good, with matches, the people can cook on the fire, and there are many things left." Chen Lufeng said excitedly.

"You first get twenty workers to come over, and I will teach them how to make matches, and then let them recruit two hundred people to make matches."

Chen Lufeng hurriedly went to find someone as soon as he agreed, and soon Chen Lufeng came over with Chen Wei and twenty workers.

"I have come to you for the purpose of making matches, and I will teach you how to make matches, so you should pay attention to the lecture." Zhou Xian looked at these people and didn't say much, and went straight to the point.

Everyone hurriedly cheered up and looked at Zhou Xian, waiting for Zhou Xian's teaching.

Zhou Xian nodded with satisfaction, and then began to teach.

The production and principle of matches are very simple, first you need to select dry and flammable wood to make small sticks, and then glue the mixture of potassium chlorate and sulfur to one end of the match stem to make matches, and then coat the phosphorus surface containing white phosphorus on the packaging box.

After Zhou Xian finished teaching, everyone suddenly realized that the method of making this match is indeed not difficult, but the person who can think of this method must be a very smart person.

Everyone looked at Zhou Xian as if they were looking at a celestial man, and their eyes were full of admiration.

Seeing them like this, I was also very happy in my heart, knowing that they were under the influence of the mysterious ball of light, and I had a sense of awe and worship for myself.

"Director Chen, let your son-in-law Chen Wei be the factory director, and lead them to recruit two hundred workers to set up a match factory in a workshop to specialize in the production of matches." Zhou Xian asked.

Chen Lufeng was overjoyed, "Thank you for the promotion!" ”

"Thank you, President!"

Chen Wei was extremely excited when he heard this.

Although it seems that the director of this match factory is not an important position, this is also a recognition of himself by Zhou Xian, he has followed his father in this chemical factory for so long, and today he is finally able to go out independently and do his own business, Chen Wei is very happy in his heart.

"Chen Wei, you do a good job, and when the match factory is on the right track, I will arrange more difficult work for you." Zhou Xian encouraged.

"Yes, President, Chen Wei must do a good job!" Chen Weimeng nodded.

After arranging the affairs of the match factory, Zhou Xian asked Chen Wei to lead twenty workers down to prepare.

After Chen Wei and the others left, Zhou Xian said to Chen Lufeng, "Our Xingjing is getting bigger and bigger now, and the scope of jurisdiction is getting wider and wider, I just received the holy decree to let me be the chief soldier of Shanxi, and after I go to Jinan, I want to bring the whole of Shanxi into the jurisdiction of our Star Society, we are short of talents now, can Mr. Chen write a letter to Mr. Song Yingxing and ask him to come to Xingjing to help us." ”

"Congratulations to the president on his promotion to the chief soldier of Shanxi, I will immediately send a letter to Song Yingxing, asking him to come to Xingjing to meet me, we haven't had a drink together for a long time, I think he will definitely work for the president, he is very obsessed with physics and chemistry." Chen Lufeng hurriedly congratulated.

"This Shanxi General Soldier is just a title, and with this title, I can justifiably manage Shanxi, so there is Mr. Lao Chen." Zhou Xian arched his hand at Chen Lufeng.

"The president doesn't have to be polite, being able to do things in Xingjing is the most correct decision I have made in my life." Chen Lufeng said with emotion.

Chen Lufeng is a person who only likes to study physics and chemistry, and it used to be an ordeal to be an official in the capital, but since he came to Xingjing, he feels satisfied and fulfilled.

"By the way, there is one more thing that Mr. Chen needs to make." Zhou Xian said suddenly.

"What's that?"

"Camera!"

"What is a camera?"

Chen Lufeng asked curiously.

"A camera is a device that uses the principle of optical imaging to form an image and record it with a negative." Zhou Xian explained.

"I still don't understand."

Chen Lufeng smiled bitterly.

"Haha, it doesn't matter if you don't understand, you go find twenty workers, and I'll teach you how to make a camera." Zhou Xian said with a smile.

Chen Lufeng agreed and hurriedly looked for someone.

It didn't take long for Chen Lufeng to come with twenty workers, and Zhou Xian didn't say any nonsense, and said straight to the point: "I came to you today just to make a camera, everyone pay attention to listen to me." ”

After that, he began to teach everyone how to make a camera.

The camera structure is very simple, including the camera obscura, the lens, and the photosensitive material, which can be completed with a few more debugging in the later stage.

Half an hour later, everyone understood how to make the camera, and their eyes on Zhou Xian began to become adoring.

Zhou Xian was already accustomed to their eyes, "This camera will be produced by Mr. Chen for the time being." ”

"It's an honor to be able to make something like this!" Chen Lufeng said excitedly.

After he got the knowledge about the camera that Zhou Xian taught him, he was immediately full of interest in this camera.

Looking at Chen Lufeng's excited appearance, Zhou Xian said with a smile, "Mr. Chen, a small camera is happy like this, and then let you make more advanced telegraphs, tape recorders and other things in the future, then won't you be happy and can't sleep, haha!" ”
