Looking up, I saw that the courtyard suspended in the air had three courtyards, seven main rooms, and wing rooms. The main room was a tall building with a courtyard. The square courtyard was full of traces of wind erosion, and was simple yet simple.
It extends endlessly along the central axis. To the south of the wing room, there is a gable dividing the courtyard, forming a courtyard of its own. In the center of the gable is a hanging flower moon gate, which is the dividing line between the inside and the outside. It spreads out like a treasure box of incense.
With a rich historical atmosphere, the past time is preserved in the cracks of the bricks and tiles.
There are one or two wing rooms in the east and west of the outer courtyard, which are smaller than those in the inner courtyard. The easternmost one opens as the main door, followed by the concierge, then the living room or study room, and the westernmost one is the garage. The overall look is majestic.
It is tall and strong, with overlapping courtyards, front verandahs and back buildings, hand verandahs, green tiles and flying rafts, countless curtains, jade saddles once lived there, lush bricks and tiles, stacked stones and scenery, and a harmonious atmosphere.
The hanging flower gate, screen wall, and partitions are all very particular. There is a courtyard inside the courtyard, and a garden outside the courtyard. The courtyards and gardens are connected. It is a large residential building, which is definitely not an ordinary house.
This place, inside and out, looks like a history book built in stone.
Because it is quietly and vigorously independent in mid-air, the whole thing seems to be integrated. The light of the flashlight shines on the surrounding corners of the house, and the faint white dots swirl in the light, surrounding every mortise, tenon, and crown of the courtyard.
Qingshui Ridge... Every square of green tiles, bricks, beast kisses, door pillars... are all filled with a completely unearthly feeling of "I want to ride the wind back", as if I was forcibly transported by the Hercules in Greek mythology -
- Heracles was lifted up in the air, and like the warrior holding the sky, this shock was so shocking that it was difficult to get away from it for a while.
No one spoke. They all looked at the building built in mid-air in silence. They really couldn't figure out how there could be a completely anti-gravity building in the world that could not cover Newton's coffin board, but still stood upright.
What about in the air?
The courtyard looks extremely peaceful, covering an area of 1 hectares, like a worldly master who has nothing to do with the world, just waiting for people to knock on the firewood.
In the old days, the king used to sit in front of Yan in front of the hall, but now the Pengmen is opened for you.
Li Gengfa's face slightly condensed: Because of those Ergou's several outrageous moves, in fact, the route he had surveyed before was not this one at all, and now he has gone astray. He is unlucky, but he has encountered even the most unreasonable things.
The way is blocked by this building in front, and there are soldiers chasing behind. No matter what the choice is, it seems that there is no other way but to go in?
"Acridine——"
The vermilion door was pushed open, and the sound was like the distant waves of the oar. Li Gengfa stepped in without fear, and the Iron King alone followed him in without changing his face.
After hesitating, Ergou limped and followed the master. For a long time, Ergou looked carefully at the courtyard that looked like the underworld or the Zenith Palace. He seemed to feel that he didn't see anything special.
Can be forced to enter.
However, once inside, it is far beyond what people think. It is not a palace like the underworld. I can see the Millennium Peak, Wufu Peak, Furong Peak, majestic and shimmering; Long live stone, tiger tooth stone, three-pointed stone,
Tutu Phosphorus is auspicious, it is clearly a normal old Beijing courtyard house.
For a moment, everyone felt a little enlightened, and it really felt like fantasy. However, when they stepped into this courtyard, the green bricks paving the floor also felt real. They couldn't help but look at it with suspicion.
But something even weirder happened next——
Because this place is really strange, everyone started looking for problems with suspicion. It doesn't matter if they look for problems, there are quite a few problems found.
First of all, no matter which house it is in, the door of this house cannot be opened because there is a big lock on it.
But as for the lock, it is something that King Suo can easily grasp, and the lock is not complicated. However, even if King Suo opens it three or two times, it seems that there is a cement wall behind the door, and it still cannot be opened.
.
Not only this door is like this, but every door is like this.
It's weird
.
This is not the only problem. In addition to the doors that cannot be opened, everyone found strangely that no matter how the courtyard is arranged, it must have its own symmetry, and they are all stuck in place.
The earth cannot be lifted.
Weird symmetry, weird facade——
Everyone had realized the seriousness of the matter and wanted to retreat to the trestle before making any plans. However, when they opened the door, something even more puzzling happened: the trestle they came from was actually on the trestle.
Disappeared so inexplicably?!!!
This is not a magic trick. How can it be possible to change it just by saying it?
The courtyard was hung in the air. On the right side was still the huge smooth mountain with a thousand-foot wall, and there were still four ferocious beasts waiting at the bottom. When they saw the people appearing, they were so excited that they screamed "Wow!"
Want to eat them.
How is this possible?
How is that possible!!!!
If the trestle never appeared, how on earth did they get to this courtyard house suspended in mid-air?
Everyone subconsciously wants to say "ghosts beating the wall", but ghosts beating the wall are also trapped in one place and keep going around in circles. They are not going around in circles now, but are trapped in one place at all, with no way out, no way out, and even no way out.
All the roads disappeared completely.
Ergou muttered something to the effect of "If I had known I would be so unlucky, I might as well have stayed on the trestle." Now everyone had a slight agreement with this, and they all looked at Li Gengfa, waiting for him to make up his mind.
"This is definitely not a fight against the wall."
Li Gengfa resolutely took the lead, but he also hesitated: He had never seen anything so weird before. If it wasn't, then what was it?
With a sound of "Pang——", Li Gengfa closed the Zhumen and looked at everyone solemnly.
"Everyone, I need you to do me a favor now."
"you say."
Now, as long as we can get out, everyone is naturally willing to put in the effort.
"I need you to help me measure the foundation here, the length of each brick, and the distance of each beam. I need to give a demonstration."
Demo?
Li Gengfa curled his lips: Yes, let's demonstrate. Let's test whether what happened is a natural disaster or a man-made disaster.
When natural disasters are found to have their origins, there will naturally be evidence to follow. If it is a man-made disaster, then this man-made factor can be eradicated.
The earth has a magnetic field from the south pole to the north pole. The magnetic south pole is actually close to the geographical north pole. As long as you compare the influence of the earth's magnetic field on the magnetic field generated by the current flowing through the wire coil and measure the strength of the earth's magnetic field in the transverse part, you can determine where you are now.
Whether the space is a "ghost" space in the scientific sense.
The first is a few meters of insulated wire; you also need a compass with a fixed pointer axis and low friction; a protractor is easy to handle; and a cylinder for winding the coil. The diameter of the cylinder depends on the length of the compass pointer. The diameter of the coil needs to be larger than
The compass has a long needle; you also need a ring frame or other object that can support the coil; a DC power supply that can provide 1A or higher current; a DC ammeter or a multimeter that can be configured as a DC ammeter with a measuring range of 0-10A——
This is a bit difficult, but the dry batteries in the flashlight can be used as long as they are handled properly.
Everyone was busy there for a long time, and they all came to report the data to Li Gengfa. However, there were still a lot of things that had not been measured, but Li Gengfa waved his hand and said, "That's enough."
He set up the compass, making sure it could rotate freely and point toward the North Pole, using a 15-turn coil around the cylinder, because for a small handheld compass, a 1.5-inch diameter tube would work, and for a pivot compass,
, a soup can or coffee can is more suitable.
When the coil is finished, scatter the objects used to wind the coil. Leave some conductors at the beginning and end of the coil.
Wire is used to connect the coil to the circuit.
Use a ring stand or other support to support the coil. Place the coil in an east-west direction, perpendicular to the plane of the coil. The compass must be in the plane of the coil so that the ends of the compass can be observed and point in the direction of winding of the coil.
Everyone watched Li Gaiwen twisting and turning, disassembling the battery, and took out a lot of coils from the equipment bag: For such a big equipment bag like his, there was no food or drink in it, it was all used for it.
Put these inexplicable things?
Li Gengfa's expression remained unchanged, his figure shuttled through the arranged coils, and he compared the obtained data from time to time, but his heart tightened tightly.
The Earth's magnetic field can be measured by balancing it with a known magnetic field. If the angle between that known magnetic field and the horizontal Earth's magnetic field reaches the appropriate value, the compass will point to a new angle 45° away from the original direction.
In the equatorial area, there is a certain angle between the direction of the earth's magnetic field and the horizontal direction, and this angle can be measured. The entire magnetic field strength will be slightly greater than the magnetic field strength in the horizontal direction.
The value of the entire test will only lead to one conclusion in the end: if there are any unknown corpses in this space - such as ghosts that can affect people's sanity and cognition, this demonstration can play a key role.
effect.
It is necessary to ensure that the DC power supply is turned off and the DC ammeter is set to read a current state in the range of 1-10A.
After stripping off the insulation at both ends of the wire, connect one end of the wire to the positive terminal of the ammeter and the other end to the negative terminal of the DC power supply. You can also use a jumper or directly connect the conductor coil.
Then connect the negative terminal of the ammeter and the positive terminal of the DC power supply to complete the entire circuit.
Position the protractor so that the zero-degree line coincides with the direction pointed by a compass needle exposed only to the Earth's magnetic field.
Slowly and carefully turn on the DC power supply switch and increase the current reading of the ammeter until the compass deviates 45° from the initial position.
At this time, the earth's magnetic field in the horizontal direction is equal to the magnetic field generated by the coil and is balanced by it.
The formula for calculating the strength of the Earth's magnetic field is as follows:
15 turns × (1.26 × 10-6) × (current value (unit: A))/2 × coil radius (unit: m)
1.26×10-6 is equal to 0.00000126, so you can multiply inches by 0.00254 to get m.
The magnetic field generated by the coil is orthogonal to the plane of the coil. Li Gengfa recorded the data with white chalk on the ground and came to the conclusion that the magnetic field generated by the coil is orthogonal to the earth's magnetic field in the horizontal direction. When the coil's magnetic field and the earth's magnetic field in the horizontal direction are exactly equal, an
The point of this situation is at the 45° angle between the two. When the equilibrium phenomenon occurs, the earth's magnetic field can be calculated by the equation.
The unit is Tesla, N is the number of turns of the coil. μ0 is the strength of the magnetic field generated by a given current, called the free space permeability, which is equal to 1.26×10-6T. R is the radius of the coil, in m.
So a 2-inch diameter coil with 15 turns requires 0.28A to rotate the compass through a 45° angle.
The magnetic field strength is: B=(15 turns×1.26×10-6T-m/A×028A)/(2×0.051m)=0.00000052T or 5.2×10-5T.
This is the range of expected fluctuations in the Earth's magnetic field at mid-latitudes.
The expression on Li Gengfa's face was very special and psychedelic at the same time, and he was stunned when he picked up the chalk.
"What's wrong?"
Everyone had just seen him writing and drawing very enthusiastically, and they were all a little surprised when he suddenly stopped.
"I was wrong. Not only is there nothing strange about the magnetic field here, it's even -" he stood up slowly, "it's perfectly normal."
In other words, this is an impossible place that has been forgotten by the world!!!
