The people of the island dug a big hole!After they invested a lot of manpower and material resources and a large amount of money, they found that they had won the prize. There was copper ore in every hole they had drilled, but there was no copper ore except in the drilling hole.They must be dumbfounded and unreasonable!The only explanation is a supernatural event.This explanation is very good.Of course, if their technology is mature and they can mine seabed minerals, they may not be fooled if they drill holes before mining. But in any case, drilling holes in the seabed for exploration costs a lot for each hole.If they drill holes for exploration again, the loss will be much less.Both methods, no matter which one, are considered to be pitting the islanders."Captain, mining and refining have been completed!" Smart No. 1 reminded in time."Yes!"Zhang Heng nodded.The mining ship was stationary and mining.In the non-navigational state, all the power could be supplied to the processing cabin, and the processing and refining speed was very fast: "Sail around the island country's mainland island to the south, the mission... to detect the surrounding waters."It's rare to come here once, and it's a long way to go. I can't just get 1,220 tons of pure copper and go back. I have to first figure out the situation in the surrounding waters, so that I can come directly when I need it in the future. It's much more convenient."Sail close to the coastline of the island country?""Yes, just sail close to it!"Zhang Heng is not afraid of being discovered at all. He sails in stealth, and even the naked eye can't catch it. Even if he encounters a ship and passes by it, he won't be discovered. There is nothing to worry about: "Keep 300 tons of pure copper, and use the rest for repair.""I think... this large amount of pure copper is enough to repair the internal circuit of the mining ship to a certain state." Zhang Heng had a plan from the beginning.The world's copper reserves are not low, and copper is also widely used. Its application in military industry is various bullets and artillery arrows.But in the entire industry, it is more widely used, and the first to bear the brunt is the circuit, because copper has better conductivity than any other metal.In this case, the demand for copper is huge. Otherwise, it would not reach the price of 58 million/1 ton. The price of concentrated copper ore, which has not yet been refined into pure copper, is between 75,000 and 80,000 yuan per ton.What if!He pushed more than 1,000 tons of pure copper to the market in one fell swoop. Not to mention disrupting the copper price, these are all trivial matters. I am afraid that many relevant departments should have targeted him at the first time, just because the quantity is too large."Alas... 920 tons of pure copper!"Zhang Heng was so distressed that he couldn't breathe, and he was bleeding continuously, but he couldn't stop: "It's worth 53.36 billion. What a huge fortune, it's a pity that it can't be sold.""Smart No. 1, you ate 53.36 billion in one breath, a well-deserved gold-eating monster. You have to make money for me, the captain, in the future, and make up for it!" Zhang Heng could only comfort himself in this somewhat funny way."Captain...I have been making money for you.""..." Zhang Heng was speechless. This sounded awkward, but there was nothing wrong with it. He couldn't refute it: "Okay, okay, anyway, such a large copper mine is lying in the deep sea. It's all ours. It's just 920 tons of pure copper. We can mine it when we need it.""Captain, there is another large copper mine in the high seas of the South China Sea, near the Luzon waters."Intelligent No. 1 is becoming more and more humane, and will provide targeted alternative comfort: "According to the detection, the reserves of that copper mine have reached 1.86 billion tons.""More than 1 billion tons, it is a giant mine."Zhang Heng didn't ask before, so he didn't know: "Has the copper mine been explored?""It has been basically confirmed that the deeper layer is rock, and there is no copper ore layer below!""Okay, 1.86 billion tons, not a small amount!"Zhang Heng was satisfied and no longer felt bad for the mining ship swallowing 920 tons of pure copper. His attention shifted to the mining ship itself: "With so much pure copper used for repairs this time, we can always repair the internal circuits, right?""I don't want to leave the captain's cabin and go to other cabins. There are sparks and squeaks everywhere, and the lights flicker and dim. More importantly, I'm afraid of being electrocuted!"Zhang Heng is still scared. He experienced it once. When he boarded the mining ship, he only moved around in the captain's cockpit and never went to other places on the mining ship. It was really terrifying."I guess it won't work...""No?"Zhang Heng's eyes widened, a little annoyed: "Where is so much pure copper?""Not enough materials!""Not enough materials?"Zhang Heng was stunned, and immediately reacted, almost slapping himself on the forehead again: "Lack of insulating materials.""Now the insulating materials seem to be polyvinyl chloride and polyethylene!""And these two seem to be able to be refined from crude oil!"Zhang Heng muttered to himself, and he already had an idea. There are many oil fields on the seabed, and mining ships can already mine oil. They use local materials and there is no cost.Okay, perfect!Just when he made a decision."Beep beep..."The intermittent prompt sounded, not an alarm, but also a more anxious prompt sound....
