The most eye-catching thing is the slender antenna on the top of the radio, which extends lightly upward as if it can touch the sky.

"Have you not seen that the water of the Yellow River comes from the sky and flows to the sea without returning..."

The sound of recitation flowed out from the radio, and although it was quietly placed in a corner of the library, it became the focus of everyone's attention.

"This, this, this... what is this? There is a human voice coming from it?!!" The people of the Tang Dynasty had never seen such a magical thing as a radio.

When they heard the voices coming from inside, their faces were filled with shock and curiosity, as well as a hint of awe.

Everyone came forward and talked about it.

"Is this the work of ghosts and gods? How can there be a human voice coming out of it?" an old man asked in a trembling voice, his eyes full of surprise and doubt.

"Could it be a magic weapon of an immortal?" A young man opened his eyes wide, his face full of disbelief.

"It's amazing that this black box can actually transmit a human voice!"

A middle-aged woman marveled at it and reached out to touch the radio, but hesitated and withdrew her hand for fear of desecrating the sacred artifact.

The owner of the bookstore, a gentle middle-aged man, looked at everyone with a smile.

After their discussion paused, he slowly spoke, “Everyone, this is not an alien object, nor is it a magical weapon of an immortal.

It's a crystal radio, a technological product recently developed by our Datang Development and Reform Commission."

"Crystal radio? What is that?" the old man asked in confusion.

The shop owner explained: "This crystal radio can receive sound signals from far away, amplify them and play them out.

The sound you hear now is being broadcast by someone thousands of miles away, and then transmitted to our ears through this radio."

"Isn't this even more miraculous than clairvoyance and super hearing?"

The shop owner nodded and continued, "Not only that, this crystal radio can also receive programs from Mingda Radio Station.

The radio station will regularly broadcast news, culture, education and other programs, so that everyone can stay informed about world affairs and learn about the world without leaving home.

He pointed to a knob on the radio and said, "Just adjust this knob to select different channels and listen to different content."

As he spoke, the shop owner reached out and adjusted the knob on the radio.

As he moved, the sound coming from the radio changed, from the recitation just now to clear and pleasant music.

"The Royal Navy crosses the battlefield, the British Empire strides across the ocean, where does the Tang Emperor point his finger..."

This change amazed everyone present even more. They all came closer to the radio, immersed in the heavenly music coming from afar.

"This crystal radio is amazing!" the old man said with emotion.

"I never thought that our Tang Dynasty could develop such a wonderful object. It is truly amazing."

"Yes, with this radio, can we always keep up with the latest news in the world?"

The middle-aged woman's eyes sparkled with anticipation. "Besides, the program broadcast by Mingda Radio Station sounds quite interesting. It's really something I'm looking forward to."

The young man seemed even more excited. He said eagerly, "Shopkeeper, this crystal radio is so amazing. I wonder if we can buy one to take home?"

"Of course!" The shopkeeper nodded, then changed the subject, "But compared to books, this radio is quite expensive."

The young man did not flinch after hearing this. Instead, he became even more excited: "Price is not a problem. As long as I can own such a magical radio, I will spend all my money!"

The old man nodded in agreement. "Indeed, a treasure like this is inestimable in value. Shopkeeper, just name your price. We will not bargain."

The middle-aged woman hesitated a bit, but finally made up her mind: "I want one too, shopkeeper. How much is this crystal radio?"

The shop owner looked at the eager eyes of the crowd and knew in his heart that this crystal radio had successfully aroused their desire to buy.

He smiled slightly and held out his palm: "The price of this radio is one tael of silver."

"What? Only one tael of silver?!" Everyone was surprised when they heard the selling price.

They thought that such a magical object must be extremely expensive, but they didn't expect it to be so "affordable".

The young man was the first to react, laughing. "One tael of silver? That's a steal! I'll go get the money now. Shopkeeper, leave one for me!"

The old man stroked his beard and nodded with satisfaction. "The owner is really a kind man. The price is really not expensive. I want one too!"

The middle-aged woman was even more delighted: "Oh, it's so cheap, my family can afford it! Shopkeeper, I want one too!"

The bookstore suddenly became lively, and people rushed to buy crystal radios.

The owner and his staff were busy as hell, but their faces were filled with happy smiles.

Soon, all the crystal radios in the bookstore were sold out.

People who bought radios went home happily, ready to enjoy the fun brought by this magical technological product.

Those who didn't buy one have placed an order with the store owner, looking forward to the arrival of the next batch of radios.

In this wave of enthusiasm, those powerful and aristocratic families quickly learned of the existence of this magical invention.

These aristocratic families each hold enormous power and resources, and they will naturally not miss any new things that may affect their status.

So, they used various means to quickly get the crystal radio and placed it in a prominent position in the family meeting hall.

In the magnificent meeting halls, the patriarchs and elders of various aristocratic families gathered together.

Their eyes were all focused on the eye-catching crystal radio.

"Can this thing really pick up sounds from thousands of miles away?" an elder from the Zheng family in Xingyang asked curiously.

"Not only that, it can also broadcast various information and knowledge." Another elder added, with a hint of worry in his tone.

A family member who worked as a deputy minister in the Ministry of Revenue reached out and adjusted the knob on the radio.

As the knob was gently turned, a majestic and powerful voice came from the radio, reporting the latest court developments in detail.

"…To further improve people's livelihoods, the Ministry of Revenue has formulated the following policies to benefit the people. First, regarding taxes, to reduce the burden on the people…"

"This..." Everyone looked at each other with expressions of disbelief on their faces.

This was because the content broadcast on the radio was exactly what the family's official who worked in the Ministry of Revenue had just revealed to them.

Before, the Zheng family was often able to deploy family businesses in advance by relying on their foresight of court decisions to maintain the prosperity of the family.

However, now, these court decisions can be known to ordinary people through a small radio, which undoubtedly breaks their long-standing information advantage.
