After wiping it clean, take the basin and rag and the three drones back to the house, open the casing with a screwdriver, and then check it with a multimeter to see if there are any damaged parts. Pen & Fun & Pavilion www.biquge.info

After the overhaul, take the tools into the room and put them away, open the fine metal particles in the bag, the yellow, orange and orange pieces are very dazzling under the light, and there is a little white and black and other variegated colors in the yellow, it should be silver, lead and other impurities, there should be copper, but the copper is also yellow and cannot be distinguished.

Another coarse bag of some metal particles was also opened, and there were some large pieces of metal and dust in various colors inside. Among them was a yellow piece of metal the size of a child's palm, and it was unknown whether it was gold or copper.

Zhang Tao picked up two bags of metal pellets, which were quite heavy, and they could weigh nearly ten catties. He took the bag to the yard and pushed the upside-down donkey out of the warehouse, and set off to the forest farm villa with two bags, a bucket full of diesel, three drones, a pangolin-style drill, and a few remote controls.

After arriving at the villa, Zhang Tao walked into the bedroom, disconnected the remote control on the QQ number of the mobile phone, and connected the remote control of a drone to the computer case with a data cable.

I looked at my watch and it was more than nine o'clock in the evening, I felt a little hungry, I went to the garden behind to pick some coriander and lettuce, and after returning to the kitchen, I cooked a pot of noodles with a rice cooker, put coriander, lettuce, and a sun-dried matsutake mushroom cut into small pieces and put it in.

Letting the noodles in the pot boil, Zhang Tao went to the yard and tied two bags of metal pellets, a bag containing tools and a pangolin-style drill to the bottom frame of the two drones with ropes. Then he went back to his bedroom and flew two drones remotely towards the oil field.

When you arrive at the grove above the oil field, you first let one drone hover in the air, and then remotely control another drone to fly around the vicinity to reconnoiter what is going on.

After no people or animals were found, the drone returned to the oil field, landed on the ground with another drone, dismantled the two bags of metal particles and the pangolin drill, remotely controlled the pangolin driller on the computer to push away the stones blocking the hole, and then remotely controlled the robot in the underground space to turn on the switches of the diesel generator and wind pump, so that the pangolin driller crawled into the underground space.

After pumping the wind for two minutes, Zhang Tao estimated that the air in the cave was almost full, so he remotely controlled the robot to stop the wind pump and diesel generator.

Then a drone flew to the hole with a few bags and flew into the underground space, and another drone flew to the tree to be on guard, the drone relied on the propeller to slap the air to generate lift-off force, and it couldn't fly without air.

When the drone also reached the underground space, it untied the two bags and poured the metal particles under the walls on both sides. Then the pangolin drill is remotely controlled to turn on the resonance frequencies of copper, iron, silver, lead and other resonance frequencies in the gold to completely resonate into powder, and then remotely control the robot to flatten the metal particles with a larger area, and then pull the pipe of the wind pump to blow the wind on the wall, so that the wind reflected by the wall blows the resonant metal pile.

The wind reflected back from the walls was not very strong, just enough to blow the powder away and leave the gold behind. After blowing for a while, the other metal impurities are almost gone, and there is still some residual powder that will be treated with water for a while.

Then remotely control the pangolin-type driller to come to the metal block, turn on the resonance frequency of other metals against the metal block to resonate the impurities into powder, and then remotely control the robot to spread the metal block and blow it against the wall, and use the wind reflected by the wall to blow the powder away.

The remote control of the pangolin-type drill climbed to a far part of the space and stopped, and then the remote control robot went to the pool and scooped some water in the basin to the two piles of gold, and slowly poured water on the gold, allowing the water to wash away the metal powder.

Then the pangolin-type drill was remotely controlled, and the spring coil was ejected, the oscillation circuit and the amplification circuit were turned on, and the gold on both sides was sent out ultrasonic waves to evaporate the water just poured.

The remote-controlled drone took out a clean broom and dustpan from the bag containing the tools, as well as a clean cloth bag and ceramic basin, and used the broom and dustpan to put the two remaining piles of gold into the bag.

The remote control robot took the ceramic basin and put two piles of gold into it, took it to an oil refining pool and put it on the side, and then started the diesel engine and the water pump for oil pumping to pump some oil in the pool, and then the remote control robot scooped a few scoops of oil into another pool filled with oil and poured it into the stove pit.

Put the ceramic basin in the pool and put the lid, and remotely control the robot to light the oil in the stove pit with a lighter, and the fire hula ignited all of a sudden, so that the robot continued to add oil to the stove pit and bake the pool, there was very little oil in the oil pool, and after a while, the oil in the pool was also baked.

Seeing that the oil in the pool was on fire, he scooped out the black heavy oil with a molten iron scoop and poured it into the pool and the stove pit, the melting point of the gold was a little more than 1,000 degrees, and the burning temperature of the heavy oil was 4,000 degrees, which could completely melt the gold.

The remote control robot turned on the diesel generator and wind pump, so that the wind on the ground entered the underground space, and after a while, the remote control robot lifted the lid of the ceramic basin to see if the gold had melted, and after more than ten minutes, the yellow financial melted and glowed green when the lid was lifted, it should be the gold gasified, so it was green.

Gold boiled at a temperature of only 2,000 degrees, and now it is less than 2,000 degrees, while ceramics have a melting point of 3,000 degrees. I am not afraid of melting gold to iron the ceramic basin or melt it with the ceramic.

Zhang Tao closed the lid and stopped adding oil to the pool and stove pit, allowing the pool and ceramic basin to cool. At the same time, the pump used to pump water is activated to pump up and pour it on the ground to reduce the temperature in the space.

After an hour, Zhang Tao looked almost there, so he remotely controlled the robot to take the thermometer and test the temperature of the ceramic basin, which was more than 30 degrees. The temperature has come down.

The remote control robot put the thermometer away, and then brought the ceramic basin down. The cooled gold stuck the lid, and it is estimated that the ceramic basin was also sticky. Zhang Tao remotely controlled the robot with a hammer to smash the ceramic basin, and a golden golden basin came out, but it was solid.
