Suspenseful puzzles?

I'm not good at this.

With apprehension, I went up to the third floor of the Scripture Pavilion.

Same bookshelves and wooden doors......

Wrong!

The wooden door on this floor, unlike the next floor, has no keyhole on it, but has a large mouth.

Next to the door hangs a wooden sign that reads: Feed it five pounds of beans, and the door will naturally open - but remember, it must not eat too much, and if it exceeds five pounds, it will spit it all out.

Feed five pounds of beans?

Obviously, this is another door opening puzzle.

That being the case, the beans should be somewhere on this level.

I looked around and found something.

I saw that among the many bookshelves, there were three wooden barrels of different sizes.

The largest barrel has 'ten catties' written on the barrel.

The barrel in the middle has 'seven catties' written on the barrel body.

The smallest barrel has 'three catties' written on the barrel.

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

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

However, not all three barrels were filled with mung beans, only the 'ten-catty' barrel was full of beans, and the other two barrels were empty.

In other words, I'm going to have to pour half of the beans from this 'ten-pound' bucket into the big mouth on the door.

But the wooden sign also said that it can only be 'fed' five catties, and it will spit out if it is too much.

What do you have to do to pour exactly five pounds into it?

Obviously, it's going to be the next two empty buckets.

I thought about it for a moment, and a smile appeared on my lips: this puzzle is too simple, at least hundreds of times easier than the dumb puzzle that opened the door with a key (if you're unlucky, you might never be able to solve that pantomama puzzle).

Just pour the mung beans in the 'ten-catty' bucket into the 'seven-catty' bucket......

I thought about the steps I needed to take as I strode towards the three barrels.

Swish!

Suddenly, all the windows on the floor slammed shut.

Since it was daytime, there was no light in the scripture pavilion, and the lighting was all based on sunlight, and now when the window is closed, the result is naturally ......

It's pitch black!

What's going on?

My first reaction was that I had been plotted, so I quickly rolled around a lazy donkey and flashed into the corner to guard against any danger that might arise at any time.

But......

There was no danger.

Oh!

It dawned on me that this was part of the puzzle – splitting the beans in the dark to make it more difficult to solve.

All right.

With the remnants of the light, I fumbled my way to the three barrels.

Start pouring the beans.

Ten catties of mung beans, not too much, too little, at least can boil a big pot of mung bean porridge to feed the family.

I silently used the technique of somersaulting, lifted the 'ten-catty' barrel with one hand, and poured it into the 'seven-catty' barrel.

While pouring, I felt the change in the number of beans in the 'seven catties' bucket with my other hand.

It's full!

I put down the 'ten-pound' barrel.

Then exhale lightly, control the internal strength air cushion around the 'seven catties' bucket, and slowly gather upward.

The beans that jumped out of the bucket during the pouring process were easily collected by me.

That's right, in the case of inability to see, how to prevent 'leaking beans' is the biggest difficulty of this puzzle.

After this pouring, the beans were divided into two parts: three catties (in a ten-catty bucket) and seven catties (in a seven-catty bucket).

Next, do the following:

The seven-pound bucket is reversed to the three-pound bucket (three, four, three), the three-pound bucket is reversed to the ten-pound bucket (six, four, zero), the seven-pound bucket is reversed to the three-pound bucket (six, one, three), the three-pound bucket is reversed to the ten-pound bucket (nine, one, zero), the seven-pound bucket is reversed to the three-pound bucket (nine, zero, one), the ten-pound bucket is reversed to the seven-pound bucket (two, seven, one), the seven-pound bucket is reversed to the three-pound bucket (two, five, three), and the three-pound bucket is reversed to the ten-pound bucket (five, five, zero).

Finish!

Poured so far, the ten-pound bucket and the seven-pound bucket contain the whole five catties of mung beans respectively.

I breathed a sigh of relief.

In fact, this mung bean feeding puzzle is evolved from the folk 'well quiz' - legend has it, there is an old man sitting by the well, with three different buckets next to him, the young man passing 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 pour it up enough, you can always divide things well.

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

Wow......

Pour five pounds of beans into it.

Whoosh.

The closed windows all popped up, and the wooden doors slipped open quietly.

Next level!

On the fourth floor of the Scripture Pavilion, the scenery is completely different from the third floor.

Murmuring water, leisurely swimming fish, Jinshan strange stones, leaves falling wandering......

In the middle of this floor, a small courtyard has been built!

In the center of the courtyard, a lacquered wooden tray is placed.

On the tray, there were ten pieces of pastry.

Can I eat it?

I looked left and right, but I didn't see anyone.

The wooden door to the upper floor was quite conspicuous, but this time, there was neither a mouth nor a keyhole.

Bang bang.

The door won't open.

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

That...... What's the puzzle this time around?

I approached the tray and saw a piece of paper pressed against the bottom of the tray.

It reads: Out of ten pieces of pastry, only one piece is not poisonous, please find the one that is not poisonous and eat it.

Poisoned pastry? You don't have to play that big, right?

Oh, there seems to be something written on the back of the paper.

Take a look: the so-called poison is actually just croton powder, and you can't eat the dead, please feel free to taste it.

This......

Who wants to eat it!

But then the puzzle is obvious.

Find out the non-toxic pastries.

How do I find it?

The easiest way to do this is to take a bite out of each piece.

Besides......

My eyes wandered around.

Since it's a puzzle, of course it won't really make you eat those pastries, there must be some kind of ingenious way to tell the difference.

And this method should be hidden in this small courtyard.

After observing for a while, my gaze stayed on the pool.

On the surface of the pool, two small rattan baskets float.

Could the way to solve the puzzle have something to do with these two rattan baskets?

With a roll of my eyes, I reached out and fished two rattan baskets ashore and placed five pieces of pastry in each.

Then put the rattan basket back on the water.

Since there is something in the basket, it will naturally sink a little deeper than when the basket was empty just now.

But I can see it at a glance - the depth of the draft of the two baskets is not the same!

Was it just a coincidence?

Or is it ......

With a stir in my heart, I took four pieces of pastry from each of the two baskets, leaving only one in each basket.

The basket swirls again on the water,

The draft is exactly the same!

I instantly realized that the weight of poisonous pastries and non-toxic pastries is not the same.

Now all I have to do is find the piece of pastry with a different weight, and the puzzle will be solved.

But at this time, new problems arose.

How can I find it?
