The next day, Qiuqiu and Li Yi got up very late.

Although Li Yi didn't eat meat last night, he was also tossed enough.

He ordered Qiuqiu's sleeping hole first and let her sleep first, and then he sat and practiced.

It was hard to suppress the evil fire, but he couldn't fall asleep again after the autumn and autumn, and he didn't know how long he fell asleep.

Originally, Qiuqiu had woken up a long time ago, but Li Yi was sleeping with her in her arms, and she didn't want to wake him up.

She knew he must have had a hard time last night.

Li Yi opened his eyes and saw Qiuqiu looking at him stupidly.

Li Yi asked knowingly: "You have been waiting for me to wake up, and you have been maintaining a posture?" Can't bear to wake me? ”

Of course, Qiuqiu won't admit it, she said: "No, I just woke up, only one second earlier than you." ”

Li Yi couldn't understand what a second meant.

Qiuqiu grinned: "One second is the time to count a number, for example, if I count one, two, three, that is three seconds!" ”

"Oh, seconds is your Qiu Pavilion's self-created time statement?" Li Yi expressed interest.

On a whim, Qiuqiu sat on the bed and talked to Li Yi about the magic of the clock.

She said that in the place she had been to in her dreams, everyone would have a magic box in their home, and the box had three long hands, called the second hand, the minute hand and the hour hand.

The three long needles are centered on the center point of the box and rotate in circles.

The second hand rotates the fastest, about one second, and one rotation is sixty seconds, which is also one minute.

The minutes turn a little slower, and one revolution is sixty minutes, and it is also an hour.

The clock turns the slowest and is twelve hours in one revolution, which is equivalent to six hours, that is, the time of a whole day.

Qiuqiu even compared, Li Yi was extremely smart, and after thinking about it for a while, he basically understood.

The magic box is actually a magic automatic schedule.

Qiuqiu described it with a nose and eyes, which shows that there is really such a thing.

What he didn't understand was that such a magical box still had everyone at home?

What kind of magical place has Qiuqiu dreamed of?

Li Yi made a joke: "Is this magical box given by the gods?" ”

Qiuqiu laughed: "Of course not!" It's made using some principle! ”

Li Yi immediately asked: "Then do you know how it was done?" ”

Qiuqiu shook her head awkwardly: "I won't do it, but I know that it relies on the rotation of gears to control the second, minute, and hour hands." ”

Qiuqiu is talking about the oldest clock structure.

She didn't dare to say modern electronic time or network time, which was more difficult to explain.

Qiuqiu was very clear when he talked about gears, and Li Yi was thoughtful.

Qiuqiu didn't learn mechanics, and she couldn't make a clock.

If she could even do a clock, let alone those old-fashioned foot-threshing machines.

Seeing how hard the farmer worked to threh the threshing with her hands, she had long wanted to invent a pedal threshing machine.

It's a pity that she has lived for twenty-two years in modern times, and she can't do anything other than knowing more theoretical knowledge than the ancients.

Seeing Senior Brother Mo's meditative appearance, she regretted telling him this a little.

Qiuqiu asked with annoyance, "Senior Brother Mo, do you think I'm stupid?" ”

Li Yi was a little surprised: "Why do you have this kind of thought, if you are stupid like this, there will be no smart women in the sky!" ”

Qiuqiu smiled reluctantly, there are some very practical things in modern times, she clearly knows their principles, but she just can't compare them.
