Just as Joey and Mr. Stotch were depicting the prospect of an empire composed of beverages and fast food, the workers finally set up and debugged the strange things in Mr. Stotch's office.

The foreman signaled that everything was ready. After just waiting for Joey's order, Joey looked out the window. Berlin had already pulled up to the night sky and said with a smile, "Uncle Henry, please allow me to turn off the gas lights in your office before the official performance."

As the gas lights went out, everything in the office was hidden into the darkness. Only the moon that had climbed up early outside the window brought a clear spot of light to the floor of the room. Mr. Stotch had not yet fully adapted to the darkness in the room, but suddenly the soothing piano sound came from his ears.

In the dark night,

The moon rises quietly in the air,

The silver moonlight poured on the ground,

In the haze, a swelling cloud quietly obscured the bright moonlight.

It covers the moonlight's smile.

At this moment, the music was rippling freely in this black night with the moonlight.

The mist that came from nowhere silently covered the moonlight on the ground. With the interpretation of the piano music of "Moonlight" by the Impressionist master Debussy, on summer nights, the hazy mood of the moonlight is fully reflected in front of everyone. (Friends who like piano music, please ignore the era of this song creation)

At the end of the song, Mr. Stotch suddenly woke up, surprised that in the dark, who could play a piano piece so skillfully, and how the ground could become when the clouds and mists were churning.

A cheerful Mozart's "Turkish March" piano music rang again, and his extremely skillful fingering and ordinary hands were several beats faster than the tunes that Mr. Stotch often listened to.

The Turkish March is performed in addition to being cheerful, and the happy notes fill every pore of Mr. Stotch, and even Mr. Stotch's hands can't help but jump with the piano music.

Accompanied by the cheerful music, colorful light suddenly lit up in the flowing clouds and mist. Between light and dark, an indescribable wonderful feeling filled Mr. Stotch's heart, between light and shadow, between clouds and mist, which were both tempting and dreamy.

When the Turkish March was played to the climax, a colorful bird suddenly appeared in the clouds and mist, waving its wings hard between the clouds and mists, as if it was about to spread its wings out of the heavy clouds and mists.

Mr. Stotch had forgotten the cheerful music in his mind, and was completely stunned by all this in front of him, blurting out, "What is this? How could there be such a beautiful bird of light?!"

The surprise of light and shadow began. With the end of the cheerful "Turkish March", a villain with a top hat appeared in the clouds and fog. As he kept taking off his hat and bowing to pay a gift, "Good night", "Thank you for watching", and other words lit up alternately.

Just as Mr. Stotch was stunned by everything in front of him, everything in the office suddenly became brighter. The bright light made Mr. Stotch narrow his eyes before he could adapt to this environment that was much brighter than gas lights.

In this bright background, Joey's smiling face is the pride that cannot be concealed in his smile.

"Jojo, what is this?! Oh my God, is this the light?! This thing is so bright!" Mr. Stotch looked in front of him, and a series of bright lights muttered to himself, "Before, I just saw them from a distance at the railway station. Now standing next to them, this is really a light within reach! Jojo, are you Prometheus? He brought the fire, and you brought the light!"

"No, Uncle Henry, this is the light of German technology, this is the credit of the gods of German science. I just borrowed their hands to show you the light of technology." Although Joey's words were modest, his expression was full of complacent.

"In Greek mythology, only Prometheus serves all living beings, but in the real German Empire, there are a group of great gods serving all living beings. Uncle Henry, you can see now that it is the product of Siemens, the great optoelectronic Empire, the electric light, and the world's first commercial electric light!" Joey said proudly.

Since then, in Joey's world, the title of the optoelectronic Empire refers specifically to the great Siemens, and there has never been any GE again. In order to eliminate the roots, the names of Ge and "Singular" companies, Joey arranged people early to register in the United States...

"Jojo, can you explain what you gave birth to just now?" Mr. Stotch looked reluctantly away from the electric light, not caring about Joey's pride, but just urging Joey anxiously, hoping that Joey could explain this magical thing.

"Of course!" Joey has always provided enthusiastic service to his free marketing ambassadors and potential customers. Joey took Mr. Stotch to the side of the piano that he couldn't see before, and introduced it first.

"Uncle Henry, the Debussy's "Moonlight" and Mozart's "Turkish March" you just heard came from its automatic performance." At Joey's gesture, the two songs rang again.

Listening to the familiar music and watching the keys of this weird piano beating, Mr. Stotch was a little confused.

"One soothing, one intense, especially the last "Turkish March", is a cheerful piece, and when it is played, it is 2 beats faster than usual. It is an automatic piano that can play any style of music." Joey said proudly.

“Any tune?!”

"Yes, any piece, as long as there is a piano piece with a musical score, it can be played." Joey emphasized confidently.

Mr. Stotch circled around the automatic piano and looked around again and again. Finally, he couldn't help but point to the violin on the automatic piano and asked, "Is this automatic piano capable of playing piano and violin ensemble in addition to playing piano music?!"

Joey signaled his foreman with his eyes, and immediately Beethoven's piano and violin concerto "Spring" in F major immediately started to ring.

"Okay!" Stotshi raised his hands and made a surrender, indicating that Joey himself had completely believed that this magical automatic piano could indeed play any piece.

"Jojo, what was the clouds and mist just now?!" Mr. Stotch still remembers the clouds that had just created hazy moonlight, and now he can't wait to start finding the answer.

Joey led Mr. Stotch to the round container and signaled a worker with thick leather gloves to remove the lid vigorously. As the lid was removed from a gap, a stream of clouds immediately flowed out from it. As the worker gently swelled with his fan, the clouds rolled forward, and the scene of clouds and mist just now appeared again.

Mr. Stotch leaned down and stirred the clouds gently. He didn't feel like he was wet. He just felt a little cold. Mr. Stotch was about to reach into the container, but Joey grabbed it.

"Uncle Henry, this is very dangerous. This thing called dry ice is very low and will frostbite you." Joey stopped him, and then signaled Mr. Stotch to pay attention to the thick leather gloves that the workers were wearing.

"This thing is dangerous?" Mr. Stotch asked nervously.

"Just pay attention to two points, it is still very safe." Joey signaled the worker to open the container completely, pointing to the vaguely visible solid inside, and said with a smile, "First, don't touch the solid directly, it will frostbite you; Second, don't inhale this gas too much. If you are covered by this gas for too long, it will suffocate due to lack of oxygen." After that, Joey waved his hand gently in the clouds of carbon dioxide, indicating that he was safe.

Mr. Stotch also stirred the clouds hard. After stirring for a long time, he didn't feel any discomfort. The expression on his face became relaxed and it was indeed very comfortable to be covered by this cool and dry gas. More importantly, looking at the swelling clouds, Mr. Stotch felt a sense of pleasure of walking in the clouds.

"The feeling created with dry ice is indeed very dreamy. As long as I can add a suitable setting, I can create a scene of heaven." Mr. Stotch commented in his heart.

After evaluating the effect of dry ice, Mr. Stotch pointed to the dull bird-shaped pattern in front of him and asked, "Jojo, is the colorful phoenix that just now transformed into it?"

"Phoenix?!" Joey laughed silently, "I like this word!"

"Yes, Uncle Henry, it was the image of the phoenix it showed you just now. It has another name, neon light!" Joey said, pointing to the phoenix pattern, the top hat man's pattern, and those beautiful words in front of him.

"Why can they come out with such beautiful and colorful light? Jojo, what kind of magic is this for you?"

"Magic, haha, Uncle Henry is still science. They are another form of light. You just need to remember that this kind of lamp that can produce colorful light is called neon light."

"Jojo, can you light them up again? I still want to watch it again. I really didn't see enough of the neon lights just now, and it looked like a dreamy neon light." Mr. Stotch, who remembered the name of the neon light, begged like a child.

Joey was about to agree, but the incandescent lamp in the office dimmed in a bad mood. Joey sighed helplessly, pointed to several square black guys in the corner of the office and said, "Uncle Henry, these batteries are not enough. It seems that today's performance is about to end here."

"Ah...Is this over?" Mr. Stotch said reluctantly as he looked at the dimming light.

"Of course not. As long as you connect to Siemens' electricity, you can appreciate everything in front of you every day." Joey smiled.

"Haha, Jojo, all the things you showed me today have made me unable to wait to sign an agreement with Siemens." Mr. Stotch turned his gaze back to Joey and asked with a smile, "Jojo, you have spent so much effort to promote the electricity from the Siemens, right?"

"Well, Uncle Henry, if you say that, I really have this original intention, because I still have a machine that has not been displayed this time. It is an electric fan that can bring coolness to the people in the room in the summer."

"Can it bring coolness to the room, can it bring coolness to a theater or tent?" Mr. Stotch asked anxiously.

"Well, if you want to bring coolness to a theater or tent, I can recommend another product, a steam refrigerator. No matter how big the tent or theatre, it can bring coolness in summer."

Looking at Mr. Stotch with a satisfied look, Joey began to paint a wonderful scene for him in the future of the Sioux Circus. "Uncle Henry, please imagine that the equipment I mentioned is combined with the circus. In the hot summer, tourists enjoy the coolness brought by the refrigerator in the tent, the children drink iced Coca-Cola, and when they are hungry, there are hot dogs, burgers and pizza."

"Use the electric lights of the Siemens to show the magical charm of light and shadow, and use Mr. Linde's carbon dioxide and Mr. Rongen's neon light to create a dreamy scene, plus the Schumer brothers' omnipotent automatic piano."
