Xu Milu, wearing slippers, knocked on Xu Minian's door. Receiving no response, she opened the door and saw a classroom. Xu Minian sat obediently in the first row, wearing headphones. An old professor stood on the podium, telling jokes to the students in a vivid way, which made the students in the classroom burst into laughter—but there was no sound at all, as eerily as a silent play.

"sister?"

Xu Minian took off his headphones, saw Xu Milu standing at the door, and immediately made a hand gesture:

"Are you leaving? Then remember to close the door behind you. Mom and Uncle Sun went to the hot spring town and won't be back today. Grandpa Cui just texted me to invite Grandpa and me to his house for dinner tonight."

As he moved, the classroom scene gradually blurred like an ink painting, revealing a semi-transparent virtual interface. The faces of the professor and students were also blurred, making them impossible to see.

"I know, I'll bring you some Beijing specialties when I come back."

After Xu Milu finished speaking, she quietly closed the door. The projection in the room returned to clear, and the old professor's teasing voice came through the headphones:

[Which student forgot to turn off their projector microphone? Come on, turn it off, or you'll lose your participation grade!]

"I'm sorry, I'm sorry."

Amidst good-natured laughter, Xu Minian quickly turned off the microphone, his face filled with embarrassment.

—Since Honghe Technology began its collaboration with the government, holographic projection technology has been widely used in real life. It has been adopted for remote classes, working from home, transoceanic conferences, and even concerts with tens of thousands of attendees, truly achieving the popularization of technology.

On their way to the airport, Xu Milu and Li Ning did not choose a taxi, but instead used software to take a solar-powered aircraft to their destination.

"Are you two going on a long trip?"

The driver was a talkative middle-aged man. Seeing Li Ning carrying large bags and small packages, he immediately started chatting:

"Oh my, science and technology are getting more and more advanced these days. Didn't they say the other day that cancer treatment has been officially included in medical insurance? My daughter is about your age. She went abroad a few years ago, and yesterday she called me crying, saying, 'Dad, there's nothing abroad, it's not good at all.' It made me so angry—"

"That's right! Just look at how the variety of ingredients is twice as good as before!"

Li Ning, who is naturally outgoing and can chat with anyone, slapped his thigh in agreement upon hearing this:

"Honghe Technology is also planning to develop some kind of 'ecological fruit and vegetable garden' project, intending to build high-rise orchards in the city so that people can eat the freshest fruit anytime, anywhere—I heard that there are protests every day abroad for this reason!"

As the conversation between the driver and Li Ning faded into the distance, Xu Milu stared out the window, feeling drowsy, and lazily yawned.

Through the glass windows of the drone, you can see four-seater drones of different colors and shapes flying over the streets. Each intersection has a dedicated flight path for drones. Traffic police officers piloting blue-black drones are directing traffic using drones. Holographic projection advertisements can be seen everywhere on the street, and the colorful lights are dazzling.

The green belt is not planted with ordinary plants; giant delicious oranges and giant delicious apples are planted in the flower beds, with unripe fruits hidden under the leaves.

The modified Bloodthirsty Rose climbs up the building, its vibrant flowers blooming on the reinforced concrete.

The fruit shop was filled with a dazzling array of giant fruits, and occasionally a few restaurants displayed giant delicious radishes and giant mushrooms as signs at their entrances.

Delivery drivers carrying takeout boxes traverse flight paths on single-person flying machines resembling skateboards; beneath towering buildings, sanitation workers wearing holographic helmets operate fully automated robots to perform aerial cleaning; and advertisements for flyer-delivered services are plastered all over the streets…

Modern China's development seems to have been accelerated, with its urban landscapes now filled with a sense of technology and magic.

"Yes, if you spend too much time in ancient times, you'll find that modern times are more comfortable."

Xu Milu took a sip of the free soda offered on the aircraft and was already looking forward to the upcoming cooking competition.
