My hotel is full of emperors throughout history.

As the carriage gradually stabilized, the emperors sighed once again.

"It's going this fast, yet it's still so stable! It's a damn treasure!"

"really!"

Li Shimin nodded in agreement and looked at Chen Mo.

"Is this the steam engine principle that Shopkeeper Chen mentioned before?"

"It can't really be called a steam engine; this thing is a hybrid, it can run on either oil or electricity."

Chen Mo replied.

While answering the question, he also brought up a navigation map on the central control screen.

Immediately, a clear and detailed electronic map appeared on the screen, with a blue arrow accurately indicating their current location.

The emperors: ? ? ?

Ying Zheng: !!!

"What is this?!"

Liu Che was the first to exclaim in surprise, leaning forward so much that he almost pressed himself against the back of the seat in front of him.

He looked at the map, then at his surroundings, his face filled with shock.

"Could this map show our current location?"

Li Shimin also stared wide-eyed at the screen.

"Scattered like stars, detailed to the finest! This is a hundred times more accurate than the most detailed map in my palace! How...how can it know where we are?"

Zhu Yuanzhang was also dumbfounded. He pointed at the clear roads and the constantly changing names of the surrounding environment on the screen, and opened his mouth.

"This...this is even more amazing than the maps drawn by our Imperial Guards! How can it move on its own?!"

As Ying Zheng looked at the screen, he couldn't contain his excitement.

Niubi!

It truly lives up to the reputation of Qin Shi Huang's chariot!

Hearing their shock, Chen Mo explained briefly while driving.

"This is called navigation. It uses satellites in the sky to determine our location and then plans a route. Wherever you want to go, just enter the place name, and it will take you there. As long as there is a signal, you won't get lost."

"In the sky..."

Li Shimin muttered to himself, staring blankly at the sky outside the window.

The car fell silent again.

Chen Mo felt it was too quiet, so he casually turned on some music.

As a melodious and rhythmic piece of modern music began to play.

"!!!"

Even the usually composed Ying Zheng was stunned.

"Whose musicians are playing music?!"

Liu Che asked in surprise.

"The sound is so pure and full...it's like being there in person!"

Li Shimin closed his eyes and listened intently, becoming increasingly shocked as he listened.

This thing can play music?!

Why didn't Manager Chen let go of that Wuling Hongguang before?

Listening to the music playing in his ears, Old Zhu wished he could immediately move a cart back to his Ming Dynasty.

Damn it!

Why didn't that kid bring out such a good thing sooner?

And why didn't you ask sooner?

Chen Mo smiled and explained when he saw their stunned expressions.

"This is a recording, which means storing the sound in advance and playing it back when you want to listen to it. This is called a sound system."

A long silence fell over the car again, with only the melodious music still echoing.

After a long while, Li Shimin, who had regained his senses, finally asked the question.

"Manager Chen, you just said that this navigation system can know where we are. Is it because it borrows the power of the heavens?"

"What kind of being is that in the sky? Could it truly possess eyes that can see a thousand miles and ears that can hear the wind?"

As soon as the question was asked, all the emperors, including Ying Zheng, looked at Chen Mo.

Chen Mo looked at the azure sky outside the front window, organized his thoughts, and began to speak.

"In our time, people created artificial stars called satellites, and with the power of huge rockets, they sent them into the heavens to orbit the earth beneath our feet."

Li Shimin: ? ? ?

Liu Che: ? ? ?

Zhu Yuanzhang: ? ? ?

Ying Zheng: ? ? ?

Several renowned emperors felt as if their brains had been completely shut down.

"Artificial stars?!"

Zhu Yuanzhang exclaimed in shock.

"Humans can create stars?! And send them into space?!"

"Exactly."

Chen Mo affirmed.

"These artificial stars are numerous and distributed in orbits at different altitudes, flying around the Earth day and night."

"They're like..."

Chen Mo paused for a moment.

"Yes, like beacon towers set up on key post roads, or watchtowers scattered throughout the territory."

"However, these beacon towers in the sky are higher and farther away, and can see the entire earth."

"They constantly send specific signals to the ground, just like beacon towers lighting smoke to transmit information."

Chen Mo pointed to the car navigation system.

"Our vehicle, and similar devices, have an internal unit that can receive these signals. It simultaneously receives signals from several different artificial stars, calculating the time and angle at which these signals arrive..."

He paused, looking at the somewhat confused but trying-to-understand expressions of the emperors, and then simplified his explanation.

"...In short, it's like determining your precise location on a map by measuring the distance between yourself and several known beacon towers. That's how this blue arrow came about."

"Hiss~!"

Everyone gasped in shock.

Although Chen Mo's explanation was rudimentary, it still gave the group a vague understanding of the principles of navigation.

But even a vague understanding was enough for them to find it hard to believe.

Humans can actually create stars?

Can it even send stars to the heavens?

Are you kidding me?

Isn't this something only a god could do?

Seeing their shocked expressions, Chen Mo added another sentence.

"These artificial stars are used for much more than just navigation. They can also observe celestial phenomena, transmit messages, and explore everything on Earth... No matter what you are doing on Earth, as long as there are no obstructions above, theoretically you can see it directly through satellites."

"Hiss~!"

Everyone gasped again.

Liu Che stared intently at the sky and murmured to himself.

"If we could control such stars, wouldn't we have the enemy's movements visible from thousands of miles away?"

"When we fight the Xiongnu, will we still have to worry about getting lost?"

"Will we still need so many scouts then?"

Ying Zheng remained silent, but his clenched fists revealed his inner turmoil.

Li Shimin was even more shocked.

They originally thought modern technology was better than theirs, but they didn't expect it to be this good.

For example, there's this self-moving car; before that, there was also the wooden ox and flowing horse of Prime Minister Zhuge Liang…

However, they created stars and sent them to the heavens to observe all things in the world.

This……

If Li Shimin had heard this before, he probably would have just thought that this person was spreading heresy and misleading the public.

but now……

Li Shimin took a deep look at the navigation map on the central control screen.

But now... the facts are right in front of him.
