For a long time they checked the room but all that was seen was a pile of treasures and some heirloom objects such as swords, arrows and modern weapons weapons were seen in the room.
"How long will the battery last if it keeps on?" albara asked as they moved to look at the other room.
"This thing will not stop burning, unless the batrenya in unplug the brother" said Devina.
"Can't you?" ask Albara astonished.
"Our nation no longer uses wet batres or dry batres that have a validity period when used, but we use endless lasting batres even in use " Devina.
"The workings of a perpetual battery are similar to the workings of a power generation generator, as we know, an electric generator is a device that converts mechanical energy into electrical energy. In fact, a generator does not create electrical energy, but instead uses only mechanical energy supplied to drive an electric charge"
Devina explained the workings of the tool batre in her handle, while continuing to follow the daughter of hena who walked in front of her.
"The working principle of synchronous generator is based on electromagnetic induction, whose principle consists only of magnets and copper wire coils"
"After the rotor is rotated by the initial drive (prime mover), the magnetic poles on the rotor will rotate. If the polar coil is supplied by a direct voltage, on the surface of the pole will arise a rotating magnetic field"
Albara nodded in understanding.
"Sir Bara studied physics at SMU when modern generators work on the principle of electromagnetic induction, first discovered by Michael Faraday in 1831. Faraday discovered that the flow of electricity could be induced by moving electrical conductors, such as wires containing an electric charge, into a magnetic field. Thus, this movement can create a voltage difference between the two ends of the cable or electrical conductor, which will occur when electric charge flows and produces an electric current" Albara commented.
"It was this discovery of Faradai that eventually developed into the AC Generator (Alternating Current) is a machine tool used to produce alternating electric current. Usually, AC generators have two wires with positive and negative polar polarity. With that circuit, it allows the two ends of the coil not to touch each other, because it is connected with one slip ring only" said Albara.
Then what about the Eternal Batrai you created?" ask Albara.
illustration of a power plant with alternating magnets inserted into copper wire coils.
"Nearly the same as the generator power plant on earth, only the difference is that your generator works with a magnet that rotates using an engine, with the aim of rotating the magnetic pole from north to south or vice versa. The speed of rotation of the machine determines the speed of exchange of magnetic poles and determines the amount of electric current produced"
Devina paused her explanation when in a very spacious room there were many stone statues of bunian warriors who were also cursed.
"In our world power plants no longer use magnetic rotors, but we have been able to create magnets whose polar poles can go back and forth on their own from north to south thousands of times a second. If this magnet is inserted into a coil of copper wire then from the copper wire will come out alternating electric current" said Devina.
"Your little sister is indeed a superhuman" Albara praised.
"It is not so that Brother Bara is simply because of the difference in time that exists in your world with the crystal world, where the time of a year in your world is comparable to thirty years in the crystal world. This means that the technology in the crystal world has advanced for thirty years while the earth world has progressed by one year. Just imagine if your earth advances for a hundred years then the crystal world advances for three thousand years"
"If Brother Bara goes to the crystal world to live there for thirty years then brother coals return to earth, so Brother Bara is already in his fifties while friends of Bara's brother here will not change because their age only increases by one year" said Devina.
"It's been over a year" Devina said.
"Wah wah wah unimaginable if devina returned to the crystal world, the contents must be a new generation" said Albara.
"Right sister, if devina returns to the crystal world now then the newborn child when Devina went to Earth is already over forty years old. while the age of devina is now only twenty-one years" said Devina.
"Look at this" said princess Hena when she saw a two-eye axe, an axe similar to the 212-axe of the Sableng wiro.
"Wait for Hena's puti don't do that." cried Devina preventing as princess Hena tried to pick up the axe that was immersed in the wall of the cave.
Devina then approached to notice the state of the ax.
"Try in a half-circle like an arrow on the side of the ax" the devina pinta shows a half-circle arrow in a clockwise direction.
True it turns out the ax is easily moved when in turn, now the position is reversed with algae du sebakah top. Two seconds later the sound of soft crockery is heard getting louder and louder, the whole room feels vibrating and the sound of crockery changes like a heavy object that is shifting.
Diding the room in front of them was seen slowly shifting revealing a very wide and long hallway, a very wide hall measuring ten meters more with a glowing dome so that you see a very flat floor hallway.
From a distance came a very subtle but never disconnected voice.
"Syuuuuuuuut" the voice became clear the closer it became.
Three minutes later a dazzling beam was seen at the end of the hallway like a dot or like a star in the sky.
"Syuuuuuutttt" the sound became clearer along with the greater the light point at the end of the hall.
"Hidden" Devina told Albara and Hena's daughter.
"The violence is like a flying car" said Devina.
Flying car is a sophisticated vehicle such as a sports car model that is equipped with round wings on the side, so the look of the flying car or flying car is more similar to a flying saucer.
Devina, Albara and princess Hena scatter towards a wooden crate in the corner of the room facing the recently opened hallway. From behind the wooden box they saw clearly that the light point at the end of the hall was increasingly shifted to see a sophisticated vehicle like a flying saucer stopped not far from the hallway door.
Of the mini-sized vehicles, roughly the size of the Agya toyota, even smaller, out came eight dwarf humans with each carrying a double-edged ax in their hands.
"Let's hurry it looks like someone has entered the daffin king's curse place" shouted a dwarf who had a white beard to give command.
