"On the first day, the big rat hit 1 foot, the small mouse hit 1 foot, a total of 2 feet, and there were 3 feet left;

On the second day, the big rat hit 2 feet, the small mouse hit 1/2 foot, and this day a total of 2.5 feet, two days a total of 2 feet

4.5 feet, 0.5 feet left.

On the third day, it stands to reason that the big mouse hit 4 feet and the small mouse 1/4 foot, but now only 0.5 feet are left and there is no opening

On the third day, you can definitely get through.

We now have the big rat hit X ruler and the small mouse hit (0.5-X) ruler

Then the hole drilling time is equal:

X÷4=（0.5-x）÷（1/4）

Solve the equation to get X=8/17

So the big rat hit 8/17 feet on the third day,

The little mouse was hit 0.5-8/17=1/34 feet

So three days in total: the big rat hit 3+8/17 feet.

Eight of the seventeen parts of three feet plus one foot. ”

This is the answer written by Fan Jianqiang, and the result is correct, but Fang Weiguo saw it in the clouds and didn't understand it at all

What does that 12345 and X mean!

He felt like he was rubbish, and he wanted to die.

When Boss Lin came, he saw the sluggish Fang Weiguo, he looked at the innocent Fan Jianqiang with some doubts, and the gloating Lin Yu, and then cleared his throat to prove that the main master had arrived.

Fang Weiguo came back to his senses in despair, and when he saw Boss Lin, he hurriedly saluted and left the imperial study with a confession.

"Yu'er, why are you still here?"

Lin Yu hurriedly said: "I heard that someone was able to treat my father's eye disease for many years, and I was worried that that person was a liar, so I came here to take a look, but I didn't expect to meet an acquaintance." Fan Jianqiang's medical skills also know something, and in this regard, he should be absolutely sure. This kind of miracle doctor is rare in my Heavenly Empire, so the child wants to see how much he is capable of. ”

Boss Lin smiled and no longer cared about Lin Yu's truancy.

How could his little caution be hidden from Boss Lin, but he didn't want to debunk it.

Besides, he didn't really want to kill Fan Jianqiang, if he wanted to, where would he summon him, he would have found someone to deal with him casually.

Fan Jianqiang saw that Lin Yu stayed, and he had a bottom in his heart, he hurriedly put on a smiling face and said, "Your Majesty, I have brought all the tools, you wait a while, I will arrange it." ”

The first is the placement of the eye chart.

This is a standard 2.5-meter eye chart, and there is no background light because there is no power. But this is not difficult to live Brother Qiang, there is no background light, can you completely bring in sunlight!

He fixed the eye chart to a papier-mâché window and covered the surroundings with a black cloth to complete a simple eye chart layout.

Then, he began to measure the measurements.

At this time, he realized that he seemed to have forgotten to exchange the meter ruler, and he didn't know the scale of the Celestial Empire too clearly, and he was a little confused for a while.

However, Brother Qiang kills pigs, not pigs, so he can always think of a way.

His current body height is one meter six, and he can estimate the approximate position of two meters five from the size of the Celestial Empire.

After everything was arranged, Fan Jianqiang took out a small wooden block and said: "Your Majesty, you are standing here and blocking one of your eyes with this wooden block, I need to know how big the words you can see clearly, so as to judge how much glasses you should wear." ”

Although Boss Lin didn't know what Fan Jianqiang said about the glasses, he still listened to Fan Jianqiang's words, blocked one eye in turn, and cooperated with Fan Jianqiang to measure his eyesight.

Deriving the approximate range of Boss Lin's eyesight, Fan Jianqiang hurriedly took out the corresponding prescription of the lens, fixed it, sent it to Boss Lin and said, "Your Majesty, put this thing on, just like this," Fan Jianqiang demonstrated it, after Ren Xi's test, this is not a hidden weapon, and it is not smeared with poison, so it is put on his eyes.

I used to see everything vaguely, to be honest, except for Ren Xi, the old man who often followed him, and the queen of the dynasty, the so-called beauties who came in later, Boss Lin still doesn't know where their beauty is.

Because it looks really blurry, he is the emperor, so he can't put his eyes on the faces of those beauties, how embarrassing it is, and it will lose the majesty of the emperor.

Therefore, it caused an even more embarrassing thing, he didn't know that the women he slept with were beautiful and ugly, and he didn't even know if these women were from his harem, what if it was a eunuch?

At this time, as soon as the glasses were put on, the blurred vision immediately became clear, especially Fan Jianqiang, who was close in front of him, looked less hateful.

Boss Lin, who just got the glasses, is like a curious baby, looking east and west, and having fun.

The vertigo caused by wearing glasses for the first time was easily overcome by him.

Lin Yu, this little bastard who often causes trouble for him turns out to look like this, yes, it's Lao Tzu's seed!

Boss Lin thought happily, because of the noisy and gloomy mood of the court in the past few days, it was suddenly like a rainbow after the rain.

"Yes, yes, much better than those so-called imperial doctors, those bastards, even said that my eye disease cannot be treated, it is really a bunch of quacks! According to my word, the Tai Hospital's income this year has been halved! Boss Lin was so happy that he directly cut half of the hospital's expenses.

Fan Jianqiang's face turned purple.

The matter of cutting Yulu is beneficial to Boss Lin, and the guys in the Tai Hospital dare not speak out, but there must be an outlet for this anger, and what is the reason for the current consequences?

Of course, it was he, Fan Jianqiang, who did something that all other imperial doctors couldn't do!

So, it was Boss Lin who was cool, and Fan Jianqiang was the one who took the blame.

Fan Jianqiang hurriedly smiled, and he had already begun to think about how to fight for the greatest interests in his heart.

Since he has been offended, it is okay to prevent offending, Brother Qiang can't pass the imperial examination, and he doesn't want to enter the army, so he can only spend some time here with Boss Lin, and an idle civil official seems to be good.

"Hehe, don't blame Brother Qiang for grabbing jobs with you, Brother Qiang, I have no choice but to do it! There are also many mouths to feed at home, how can this be done without rights? He thought so in his heart, but now he was talking about something else.

"Your Majesty, these glasses have not been debugged yet, this is not the best solution at the moment, wait for us to continue to look at the eye chart, if we can achieve an acuity of 5.0 to 5.1, it proves that the lenses are the most suitable." Otherwise, the lens adjustment is not appropriate, which will affect the vision, and the decline rate may be faster. ”

Fan Jianqiang is certainly not alarmist.

If these glasses are not well matched, the impact will not be small.

Boss Lin felt that what Fan Jianqiang said made some sense, so he sat down and cooperated with Fan Jianqiang's test.

Seeing things clearly is already an inevitability, and as the emperor, Boss Lin still has this patience. At this time, he couldn't help but congratulate himself on how correct his choice was, and sure enough, there was an unexpected surprise in leaving Fan Qiang's life.
