"Brother, could it be that among the things you brought there are also timekeeping tools?"
Unlike Cheng Yaojin and Yuchi Gong, who were both careless, Li Er roughly guessed Zhou Yu's intention with just two questions.
Today's Tang Dynasty still mainly relies on sundials and dripping water to tell time.
Because this thing had a large error, Emperor Li Er often suffered from it.
For example, the time for attending court is not unified among everyone.
So much so that many times, he has to prepare for a long time in advance.
"Yes, Your Majesty, please look at this."
Since they have decided to promote it through Cheng Yaojin and Yuchi Gong, they naturally have to use some extraordinary means.
He first showed the mechanical watch around like a hostess, then said mysteriously, "This thing is called a watch. It can not only accurately display time, but also be accurate to the second."
As he spoke, he pointed to the constantly rotating second hand.
Not to mention Cheng Yaojin and Yuchi Gong, even Emperor Li Er had never seen such a magical thing.
The silver case exudes a light metallic luster.
The dial is a piece of crystal clear crystal, shining brightly in the sunset.
Inside the dial are three pointers of different lengths and thicknesses.
The thinnest and longest one among them was beating rhythmically, as if it was really calculating time.
At just one glance, Li Er was attracted by the exquisiteness of the mechanical watch. "Brother, how do I use this to check the time?"
"Boy, tell us about it."
"That's right, that's right, tell us about it quickly."
Cheng Yaojin and Yuchi Gong were also attracted by the exquisiteness of mechanical watches.
He was staring at the watch with his big eyes, looking up and down.
Seeing this, Zhou Yu didn't keep the question in suspense and directly pointed to the scale on the dial to explain.
According to the Tang Dynasty's timekeeping method, a day consists of twelve hours, and one hour is two hours.
In order to help Li Er and others better understand the scale on the dial, Zhou Yu simply told them that one scale represents half an hour.
When I heard that this small watch could accurately correspond to the twelve hours, I was very surprised.
Cheng Yaojin, staring with a pair of bull eyes, could not help but yell, "You bastard, I never thought there would be such a magical thing in the world."
"This thing is truly magical, boy, I wonder where it came from?"
Yuchi Gong looked excited, his eyes rolling around, obviously thinking about how to grab a vote.
If I could make more of these things, wouldn't my silly son be able to become the richest man in Chang'an City?
"Brother, this is good, the more the better."
Seeing that Cheng Yaojin and Yuchi Gong were about to start fighting over the watch if they had a disagreement, Li Er grabbed the watch and put it on his wrist without any hesitation.
He saw his target being snatched away by Li Er.
Cheng Yaojin and Yuchi Gong immediately looked at Zhou Yu with unfriendly expressions.
"Uh~ This item will be sold in supermarkets in the future. You can ask His Majesty for details."
Being stared at by two famous generals of the Zhenguan period, Zhou Yu actually felt like he was being stared at by a tiger.
Seeing that Li Er was still looking at the watch on his hand with admiration, he immediately tried to divert the blame.
"A supermarket again?"
"It seems that there must be other treasures in this box that will be sold in the supermarket."
…
After all, he was a famous general in the Zhenguan period, and his IQ was indeed high.
Before Zhou Yu could react, the two guys rushed towards the box.
The next moment, they took out all the contents of the box.
"What is this, boy?"
Cheng Yaojin was holding a lighter in his hand, his face full of curiosity.
As he spoke, he had already pressed the button of the lighter.
Click.
As a crisp sound was heard, a faint blue flame instantly started burning.
Seeing this, Cheng Yaojin was stunned, and then quickly loosened his fingers.
But after a moment, he pressed the button again with a look of surprise.
Every time you press it, the flame will ignite instantly.
For a moment, Cheng Yaojin was like a boy playing with fire, and began to fiddle with the lighter.
"This thing is called a lighter. It has a similar function to a tinderbox, but it's a thousand times more effective."
This thing is cheap, so Zhou Yu directly took a box of samples.
Seeing that everyone around him was curious, he immediately took the food and distributed it to others.
Even Princess Mingda held two or three in her hands.
"Little Nianjun, is this what you are using?"
As soon as the little guy got the lighter, he couldn't wait to press it like Cheng Yaojin.
Click.
Although it was a bit difficult to press, it was a success.
Seeing the flame burning on the lighter, the little princess immediately danced with excitement.
"Then what is this?"
Compared to the lighter, Yuchi Gong was obviously more curious about the flashlight that emitted a metallic luster.
After playing with it for a while, he quickly found how to turn on the flashlight.
Because the battery was put in early.
Yuchi Gong simply pushed forward lightly, and a dazzling light emanated from the flashlight.
"Wow, little guy, this is amazing~"
The little princess was also surprised to see the flashlight shining.
Before Yuchi Gong could even take it in his hands to play with it, she stuck out her little butt and snatched it away.
When he first saw the flashlight being snatched away, Yuchi Gong wanted to get angry.
But when he saw clearly that it was the little princess who did it, he immediately lost his temper and started rummaging through the box again.
