The physics guy laughed and moved his finger down the list.
"Of course there is, old man. This is the blueprint of the steam car I designed for you. You just need to tell people to follow the steps."
At this point, Zhang Yuan thought of a question. He turned to look at Qin Shihuang and asked.
"Grandfather, did you manage to kidnap the heir of the Mohist School that I asked you to kidnap?"
The word "kidnap" made the First Emperor stunned.
Is it so straightforward?
Tie directly?
Rubbing his nose, the First Emperor looked away awkwardly and nodded slightly: "I have invited all these descendants of the Mohist School to Xianyang."
Although what Xiao Zhang said was true, he was indeed kidnapped.
But he couldn't admit it.
This is so embarrassing.
Zhang Yuan smiled cheerfully, "It's good that they've tied him up, it's good that they've tied him up."
[Otherwise, even if I give you this blueprint, you might not be able to figure it out!]
[Also, Grandfather, with that guilty look on your face just now, you didn't really think we couldn't tell you were kidnapped, right?]
Qin Shi Huang: ....
He bit his gums, feeling frantic.
Xiao Zhang!
He wanted to see whether these descendants of Mohism were really that powerful.
If you can't figure it out, drag them all out and beat them up!
Not wanting to continue this topic, the First Emperor looked at the items under the steam car and asked in confusion.
"What is this thing?"
Zhang Yuan took a closer look.
Hey, who in later generations doesn’t know this thing?
I don’t know which big shot came up with the idea and gave it to the First Emperor.
This was Wang Yongyuan's opinion. He coughed lightly, drawing everyone's attention to himself.
"Ancestor, this is the item I gave you."
The First Emperor looked at Wang Yongyuan, waiting for his answer.
Wang Yongyuan rolled up his sleeves, took off the watch on his wrist and handed it to Qin Shihuang.
"Grandpa, please look, this is a watch. I prepared it for you."
[Hahahaha, now you can even give away watches? Could it be that Uncle Wang wants to teach our ancestors about modern timepieces?]
Facts have proved that Zhang Yuan's guess was correct. What Wang Yongyuan wanted was to educate Qin Shihuang about the current time table.
He felt that the twelve-hour timekeeping method used during the Qin Dynasty was not very scientific.
After Qin Shihuang took the watch, he looked at the dial with his eyes slightly narrowed.
I suddenly looked up at the clock on the wall of the supermarket.
Thoughtful.
This watch looks so much like the round thing in Xiao Zhang’s supermarket.
Although it is much smaller, it still has three needles inside.
He remembered that Xiao Zhang always told the time by looking at the round thing on the wall.
Could this be the tool used to tell time in later generations?
Wang Yongyuan's next words confirmed Qin Shihuang's guess.
"Grandfather, this thing is called a watch. Generally speaking, we wear it on our wrists. This way, we can easily grasp the time at any time."
The First Emperor's eyes lit up.
Keep track of time at all times?
Good stuff!
"Very good, tell me, how should I look at this thing?"
Wang Yongyuan waved his hand and said, "Grandfather, please don't be impatient. Before I tell you how to use this thing, I want to first explain to you how we, the later generations, calculate time."
Qin Shihuang nodded and listened attentively.
"Okay, you talk, and I'm listening."
He was extremely alert and made sure to remember how time was calculated in the future.
If it is useful, the Qin Dynasty can also adopt this timekeeping method.
After Wang Yongyuan received feedback from Qin Shihuang, he continued with a smile.
"Ancestor, first of all, we in later generations have the same 12 months in a year as the Qin Dynasty. This is the same."
It’s just that later generations used the solar calendar, while the Qin Dynasty used the lunar calendar.
But Wang Yongyuan felt that there was no need to say this.
Today's focus is still on time.
The First Emperor nodded: "Well, go on."
Wang Yongyuan continued: "However, in later generations, we divided the day into 24 hours, and timekeeping became more accurate."
The Qin Dynasty used a twelve-hour algorithm, which was too general a timekeeping method.
"24 hours? Tell me in detail."
The First Emperor was very interested, and 12 hours actually became 24 hours.
It seems that the timekeeping method of later generations is more detailed.
Wang Yongyuan did not continue to talk about the time, but took the list and pointed to a book at the bottom of the list.
"Grandfather, I also provided this book."
The First Emperor was puzzled, wondering why the man in front of him suddenly changed the subject.
Could it be that this method of timekeeping is related to this book?
"oh?"
He responded with a questioning monosyllable.
Wang Yongyuan smiled and explained, "Ancestor, this book simplifies the arithmetic method. We later generations all use Arabic numerals and letters to count, which is more convenient."
The First Emperor was still confused and waited with his eyes for Wang Yongyuan to continue.
Wang Yongyuan is not like Zhang Yuan, who likes to keep people in suspense.
He briefly introduced the new items and brought the topic back to time.
"I'll explain the Arabic numerals later. Now let me return to the question of time."
"We divide time into 24 hours, each hour has 60 minutes, and each minute has 60 seconds."
"Look at this watch. The longest hand on it is called the second hand, and it also moves the fastest."
"One revolution of the second hand equals one minute."
"Look, ancestor, after it passes this 12, the middle needle will move forward a small space. This needle is called the minute hand."
"When the minute hand reaches 12, the shortest hand will move forward one space, and this hand is the hour hand."
The First Emperor seemed to understand something and shook his head slightly.
Second hand, minute hand and hour hand?
Quite interesting.
Wang Yongyuan glanced at Qin Shihuang's reaction and smiled slightly.
"Grandfather, you see, this kind of timekeeping rules can be clearly defined down to every second. Our later armies basically calculate in minutes and seconds."
"Just like the time on this watch right now."
Wang Yongyuan pointed at his watch and said with a smile, "The hour hand is at 10, and the minute hand is at the third square between 6 and 7, so the time is now 10:33."
"You see the sky is dark, so it's 10 o'clock in the evening, which is 10 o'clock in our 24 hours."
Qin Shi Huang's arithmetic was reliable, and he quickly figured out why it was 33 points.
His eyes lit up, but then his brows tightened slightly again.
This kind of time calculation is too detailed and does not seem to be very useful for the Qin Dynasty.
After all, the Qin Dynasty was not like later generations, where everyone could learn arithmetic.
How could they figure out what time it was?
Wang Yongyuan had thought of this a long time ago.
Seeing the expression on Qin Shi Huang's face, he immediately mentioned the next item.
