??Suspense puzzle?

I'm not good at this.

With a nervous mood, I went up to the third floor of the Sutra Pavilion.

The same bookshelf and wooden doors...

wrong!

The wooden door on this floor is different from the next floor. There is no keyhole on it, but it has a big mouth.

There is a wooden sign next to the door, which reads: Feed it five kilograms of beans, and the door will naturally open - but remember, you can't eat too much, if it exceeds five kilograms, it will spit it all out.

Feed five kilograms of beans?

Obviously, this is another open puzzle.

In that case, the beans should be somewhere on this floor.

I looked around and found something.

I saw three wooden barrels of different sizes placed among the many bookshelfs.

The largest wooden barrel has the body of the barrel with "ten kilograms".

The wooden barrel in the middle has the barrel body that says ‘Seven Jin’.

The smallest wooden barrel has the body of the barrel with 'three jin' written on it.

I walked closer and took a look-oh, isn't this the jade of life?

Of course, most people are used to calling it mung beans.

However, not all three buckets contain mung beans, only the "ten kilogram" wooden bucket is filled with beans, and the other two buckets are empty.

In other words, I have to pour half of the beans in this "ten kilogram" bucket into the big mouth on the door.

But the wooden sign also said that it could only be "feeded" five kilograms, and it would be spit out if it was too much.

What should I do to pour it into the whole five pounds?

It is obvious that we have to rely on the two empty buckets next to us.

I thought about it carefully and a smile appeared on the corner of my mouth: This puzzle is too simple, at least several hundred times easier than the puzzle that used the key to open the door just now.

Just pour the mung beans from the "ten kilogram" bucket into the "seven kilogram" bucket...

While thinking about the steps I should do, I stride towards the three wooden barrels.

Swish!

Suddenly, all the windows on the floor suddenly closed.

Since it was daytime, there were no lights in the Sutra Pavilion, and the lighting was all based on the sun. Now when the windows were closed, the result was naturally...

It's pitch black!

What's going on?

My first reaction was that I was plotted against, so I quickly rolled around and went to the corner of the wall to guard against dangers that might occur at any time.

but……

No dangers arise.

oh!

I suddenly realized: It turned out that this was also part of the puzzle - splitting beans in the dark to increase the difficulty of solving puzzles.

All right.

With the memories left when the light was left, I groped to the three wooden barrels.

Start pouring beans.

Ten kilograms of mung beans, no more or less, no less. At least one can cook a large pot of mung bean porridge and feed the whole family.

I silently used somersault technique, lifted the "Ten Jin" wooden barrel with one hand, and poured it into the "Seven Jin" wooden barrel with a thunderous hand.

While pouring, I felt the change in the number of beans in the '7 jin' bucket with the other hand.

Full!

I put down the 'Ten Kg' wooden barrel.

Then let out a breath, control the internal energy cushion surrounding the "Qianjin" barrel, and slowly gather up.

I easily took back the beans that jumped out of the bucket during the bean pouring.

Yes, how to prevent "leakage of beans" when you cannot see objects is the biggest difficulty in this puzzle.

After this time, the beans were divided into three pounds and seven pounds.

Next, the same applies:

The seven-jin bucket is inverted to the three-jin bucket, the three-jin bucket is inverted to the ten-jin bucket, the seven-jin bucket is inverted to the three-jin bucket, the three-jin bucket is inverted to the ten-jin bucket, the seven-jin bucket is inverted to the three-jin bucket, the ten-jin bucket is inverted to the seven-jin bucket, the seven-jin bucket is inverted to the three-jin bucket, and the three-jin bucket is inverted to the ten-jin bucket.

Finish!

At this point, there were five kilograms of mung beans in the ten-kilogram and seven-kilogram buckets respectively.

I breathed a sigh of relief.

In fact, this mung bean feeding puzzle evolved from the folk "Q&A by the Well" - legend has an old man sitting by the well with three different buckets of water beside him. When the young man passed by, the old man asked the young man how to accurately divide the water in the bucket into two halves - as the size of the bucket changes, the difficulty and solution of this puzzle will also change a lot.

In general, as long as you make a deal of it, you can always divide the things well.

I walked towards the wooden door with a ten-pound bucket.

Wow...

Pour the whole five kilograms of beans in.

Whoosh swish swish swish.

All the closed windows bounced up, and the wooden door quietly slid open a crack.

Next floor!

The fourth floor of the Sutra Pavilion has a completely different view from the third floor.

Gurgling water, leisurely swimming fish, strange stones in the brocade mountain, and falling leaves...

A small courtyard was built on this floor!

In the middle of the courtyard, there is a lacquered wooden pallet.

There were ten pieces of pastries on the tray.

Can you eat it?

I looked around and saw no one.

The wooden door leading to the upper floor is very conspicuous, but this time, there is neither a mouth nor a keyhole on the door.

Bang bang.

The door cannot be pushed open.

Of course I can't push it away, I haven't solved the puzzle yet.

Then...what is the puzzle this time?

I walked up to the tray and saw a piece of paper pressing on the bottom of the tray.

The paper reads: Among the ten pastries, only one is not poisonous. Please find the non-toxic piece of pastries and eat them.

Poison pastry? Don’t you have to play so big, right?

Oh, it seems that something is written on the back of the paper.

Turn over and take a look: The so-called poison is actually just croton flour. If you can't eat it, please feel free to taste it.

this……

Who wants to eat it!

But in this way, the puzzle becomes obvious.

Find out non-toxic pastries.

How to find it?

The easiest way is to taste one bite by one.

besides……

My eyes were circling around.

Since it is a puzzle, of course you won’t really let you eat those pastries. There must be some clever way to distinguish them.

And this method should be hidden in this small courtyard.

After observing for a while, my eyes stayed in the pool.
