Unfortunately, the scene of loneliness and long-awaited vision did not happen.

He had poured three buckets of water in a row, and nothing else had happened, except for a large wet patch of the ground.

Lonely Vision was very depressed: "What do you mean, but give a hint!" ”

The knife price went into the broken house to view.

The simplicity of the house is a sign of the poverty of the owner's family: at the west end of the room, the few planks that had been made into a simple bed, are now covered with dust. At the east end of the room, there was no pot on the empty stove.

On the north wall, there are rare and strange scratches, of different shades. The price of the knife came close and carefully analyzed the trace.

"Hope, tank, automatic, water." The price of the knife was guessed, and several words were recognized.

He began to search the room for the tank.

But the room is about 20 square meters in total, and the built-in objects are simple and visible, and there is no tank.

Perhaps, outside the house?

Knife price walked out of the room.

The lonely vision that gave up pouring water immediately came up: "How is it, Brother Dao, do you have any clues?" ”

A teenager envied the chivalrous brotherhood in martial arts novels, and came to recognize his brother on the spot.

Of course, the lonely vision who has suffered a loss has learned to be "fine": he is only verbal now, but he will not be stupid, ignore it, and treat others as brothers!

The price of the knife didn't care about what the lonely vision called him, he shared his discovery with Xia Weiran: "Find the cylinder." ”

Xia Weiran didn't ask much, and directly started looking for the cylinder. For her, in addition to the cost of death, the price of the knife has to be quite reliable.

And, the article of asking for money is enough for Xia Weiran to define his favorability value as 0.

After all, it's a partner who temporarily helps each other, so it's not set to a negative value, which will make her look cautious!

There is no tank on the front of the house, this is an obvious fact, Xia Weiran went around the back of the house, and still didn't see the tank.

Xia Weiran didn't doubt the price of the knife, she only felt that she must have missed something, she searched more carefully, inch by inch, and even opened the rotten haystack behind the house to see.

In the end, nothing was gained.

Back at the front of the house, Xia Weiran asked the price of the knife: "I didn't see the cylinder, are there any other clues?" ”

Lonely vista raises your hand.

Xia Weiran looked at him: "Huh? ”

"I think it......" Lonely Vision whispered to Xia Weiran: "No one will put the cylinder in the back of the house!" You just looked like that, obviously looking in the wrong direction! ”

Xia Weiran: "Don't say it earlier!" ”

She also remembered why she didn't have any common sense in life and ran to the back of the house to find a water tank?

This kind of thing, either inside the house or in front of the house!

The problem now is that there is no room in the house, and you can't see the front of the house.

Lonely Vision boldly guessed: "The cylinder won't be stolen, right?" ”

The knife price looked at him with the eyes of an idiot: "Who is okay to steal the water tank?" ”

Speaking of this, Xia Weiran has the right to speak!

When she took the water from the east before, she thought about taking it away!

Ahem, fortunately, in the end, I successfully used the bowl to get water, and I didn't take the water tank away.

Thinking of the bowl, Xia Weiran had a new idea: "The price of the knife, do you have a tank?" ”

Knife Price: ......

He's not a grocer!

didn't hear the reply of the knife price, but after receiving the death ray of the knife price, Xia Weiran chose to continue looking for the cylinder.

At this time, Lonely Vision put forward a very important idea: "Could it be that the tank will be blown away by the wind?" ”

Xia Weiran's eyes lit up: It's not impossible!

After all, the cylinder is round, assuming that it falls to the ground due to some external force, and then encounters a strong wind, the wind exerts a thrust to the cylinder, according to the force analysis, when the thrust is greater than the gravity of the cylinder, the ground friction and air resistance, the cylinder will move relatively!

Yes, yes, and, in the calculations, the air resistance is negligible!

As the old saying goes, learn mathematics, physics and chemistry well, and you will not be afraid to go all over the world!

Xia Weiran looked at the door: Suppose, there used to be a tank here. One day, it fell. Another day, a strong wind struck.

Where will it go?

Xia Weiran looked into the distance, trying to find such a rolling water tank.
