When I withdrew from the arms shopping street, it was already past eight o'clock in the evening. Pen ~ fun ~ pavilion www.biquge.info

Nie Zheng returned to the palace and looked at the gold and silver treasures that were still piled up in half, but his mood was no longer as excited as he was when he saw them.

Even if all the remaining gold and silver are taken into the Jinhuo Commercial Street, it is estimated that it will be able to exchange tens of billions of funds at most.

You must know that in just one hour, he has used the more than 900 meteor hammers to exchange nearly 500 billion in liquidity.

Compared to the value of those meteor hammers, the gold and silver treasures in the palace are really insignificant.

After standing at the door of the main hall for a while, Nie Zheng was ready to leave, and the remaining gold and silver treasures in the palace could only wait until three days later before moving them into the Fire Commercial Street.

Back in the square, Nie Zheng ordered on the spot to let two hundred clone soldiers follow him and go down to the dungeon again to explore AR ores.

It took more than an hour for Nie Zheng to lead everyone down the secret passage between the fins and tails of the mermaid statue and descend into the underground palace in an endless stream.

Since they had explored the dungeon once before, they knew that there was no threat here, so Nie Zheng and the others didn't have to worry too much about it this time, after entering the dungeon along the rope, Nie Zheng led two hundred clone soldiers and slowly walked towards the depths of the cave along the spiraling stairs.

Soon, everyone came to the mysterious cave where they picked the seven-colored spirit fruit last night.

At this time, in the pool in the middle of the cave, the corpse of the giant mermaid that was more than ten meters long was still floating quietly on the surface of the water, if it weren't for its large mouth full of fangs and sharp teeth, revealing a small section of half-dead dark green vines, Nie Zheng would even think that there was no seven-colored spirit fruit here at all.

Standing on the edge of the waterhole, Nie Zheng thought for a moment, and decided to let Jack teleport the equipment to detect AR ore on the spot.

Just before Nie Zheng withdrew from the arms shopping street, Jack had promised to lend him a set of high-tech AR element detection equipment, and Jack could teleport it out at any time as long as he needed it.

"Jack Jack, please hear back."

"Sir, what are your orders?"

"Immediately teleport that high-tech equipment to detect AR ore."

"Okay, sir, wait a minute......"

After waiting for less than five minutes, Jack teleported a silver-white metal sealed box to Nie Zheng's side.

After seeing this metal sealed box, Nie Zheng couldn't help but be stunned, and said secretly: "What the hell is this?" Jack is too unreliable, I asked him to lend me a set of detection equipment, why did he get a metal box for me? ”

With doubts in his stomach, Nie Zheng ordered one of the clone soldiers to open the box.

As the metal sealed box was opened, the doubts in Nie Zheng's heart deepened.

Inside the silver-white metal box were sixty finger-sized dark black "spikes", as well as an LCD screen similar to a tablet.

Looking at the shape of these "spikes", they look very much like small spinning tops.

Looking at these metal "spinning tops", Nie Zheng couldn't help frowning, so he asked Jack through the superchip and asked him what was going on? Why did you teleport such a strange thing?

On the spot, Jack patiently explained to him that inside this silver-white sealed metal box is a set of very advanced AR element detection equipment, those small metal "spinning tops", they are small drilling robots produced by future technology, with the function of scanning and detecting underground AR elements.

As for the tablet-like LCD screen inside the box, it is actually a sensing and positioning display, as long as those small robots drill into the ground, once they discover the existence of AR elements, they will transmit detailed detection data to the positioning display as soon as possible.

After having the detailed data transmitted back by the small robot, Nie Zheng can clearly know where the AR ore is buried underground through the data on the positioning display.

After listening to Jack's explanation, Nie Zheng was immediately impressed by the metal "top" in the box.

In order to be able to find out the specific location of the AR ore as soon as possible, Nie Zheng immediately activated all the sixty small robots in the metal sealed box according to the method taught by Jack.

Buzz Buzz......

Sixty small robots, within their top-like metal bodies, suddenly poked out a few tiny mechanical legs, and then they quickly crawled out of the box like a swarm of nimble spiders.

I saw dozens of small robots constantly moving around the waterhole, and suddenly, there was a slight "click" sound in the cave, and then, these sixty small robots all folded their mechanical legs and turned into sharp metal "tops" again

Dozens of metal "spinning tops" were spinning wildly on the ground, and at this moment, these small robots seemed to have really become spinning tops, and at a terrifying speed of tens of thousands of times per second, they disappeared in an instant in the bursts of flying dust.

After a few moments, the darkness of the cavern was quiet again.

At this time, Nie Zheng couldn't close his mouth for a long time in surprise.

After a long while, Nie Zheng slowly came back to his senses, and at this time, he immediately flashed his flashlight and came to the place where the robots disappeared.

I saw that in the entire cave, on the uneven ground, dozens of small piles of dust suddenly appeared, gently brushing away the dust with your hands, and on the hard ground, a round hole the thickness of a thumb suddenly appeared.

The hole was filled with dust, and presumably when the small robots drilled into the ground, they were frantically drilling down, and at the same time squeezing all the dust behind them.

Seeing this scene, Nie Zheng was secretly frightened, and said in his heart, this group of small ground-drilling robots is also too perverted by Nima, right? The kinetic energy released by something the size of a finger is so terrifying.

It seems that the technological equipment of the future world is really unimaginable.

Sixty small robots, all of which went underground to detect AR ore, and now, Nie Zheng and the others had to stay in the cave and wait.

Nie Zheng found a flat place and sat down, then took the positioning display inside the metal box in his hand, and kept an eye on the detection movements on it at any time.

In the LCD screen, 60 green dots appear, and next to each green dot, their location and depth of drilling are displayed.

At present, the robot that has penetrated the deepest into the ground has reached a hundred meters underground, and the speed is simply shocking.

According to Jack's prompt, all the small robots are now transmitting green signals, and if some of them turn red, it means that they have found the specific location of the AR ore.

I have to say that the AR detection equipment that Jack lent himself is very easy to use, although it looks very tall, but as long as you know how to control and identify them, you will soon know how to use them.

In this way, Nie Zheng held the LCD screen, leaned against the stone wall and waited slowly.

Basically, every ten or twenty minutes, Nie Zheng will observe the movement on the display screen, as long as there is a red detection signal on it, Nie Zheng will record and archive it as soon as possible.

Before I knew it, four hours had passed.

At this time, it was already late at night, to be honest, Nie Zheng was already sleepy, but for the sake of those large-scale AR ores, he had to wait no matter how sleepy he was.

Because, Nie Zheng knew very well in his heart that as long as he found out the specific location of AR ore, he would be able to carry out large-scale mining immediately.

At that time, if the content of AR ore mined is very high, not to mention the No. 7 Arms Block, even the No. 8, No. 9, and No. 10 Arms Blocks will all be successfully opened.

If he really unlocked all the permissions of the entire arms shopping street, then he could have yelled at the sky, "Lao Tzu's goal is the sea of stars!" ”

Just when Nie Zheng was still immersed in the beautiful fantasy of the future, suddenly, the LCD in his hand finally had an abnormal reaction.

I saw that the area located in the middle of the LCD monitor, the green signal on it instantly turned red, and then, a prompt window popped up in the display.

"The discovery of AR element vein, 832.5 meters above the surface, vein grade 'SSS', total AR ore reserves, is currently being explored and scanned......"

"Finally found AR ore!" Hearing this result, Nie Zheng was overjoyed.

But soon, he calmed down, because according to the prompt of the positioning display just now, the location of the ore vein was deep from his location, more than 800 meters deep.

This distance and depth made Nie Zheng feel a little headache, and for now, he didn't know if he had the ability to mine.

Drilling more than 800 meters underground to mine ore is a very huge super project, which is 10,000 times more difficult than going deep underground to extract oil.

You must know that oil drilling only needs to drill bits deep into the seabed to extract oil, while AR ore hidden deep in the seabed requires very advanced and huge equipment to be able to extract.

It's a big problem.

Nie Zheng held the LCD monitor and looked very depressed.

He had been thinking about finding out the specific location of the AR ore earlier, but now that he had finally detected it, he found that it was actually a promising but unreachable target.

Just when Nie Zheng was still in deep distress, suddenly, a prompt window popped up again above the monitor: "A total of three AR element veins have been discovered, one of which is at the bottom of the 1,100-meter deep sea, and the difficulty of mining is easier to ...... than the other two places."

After seeing the information in the prompt window, Nie Zheng was stunned for a moment, and said secretly: "Hey, this set of detection equipment actually has an intelligent analysis function?" ”
