The gold mountain in front of you is about 5,000 meters high, with a circumference of more than 20 kilometers, and there are some small gold mountains nearby, and the total gold mine covers an area of more than 100 square kilometers.

In this 100 square kilometers, Lu Wei couldn't calculate how much gold there was, but it was just what he saw with his eyes, and he silently calculated in his heart that the amount of gold was probably more than a few million tons.

You know, in the earth, the gold content is about 5 parts per billion, and the total mass is about 4.8 billion tons, which sounds like a lot, but 4.7 billion tons of gold is distributed in the earth's core, 86 million tons in the mantle, 9.6 million tons in the earth's crust, and 4.4 million tons in seawater.

Because the gold content is too low and the mining is too difficult, the actual total amount of gold that can be mined on the earth is only a hundred thousand tons.

And the amount of gold that can be mined in this gold mountain in front of Lu Wei is probably just as many million tons, which is more than the amount of gold that can be mined on dozens of earths.

And those gold mines on the earth, as long as there is 1 gram of gold in a ton of rock, it can be called a rich ore, containing more than a dozen grams, which is considered a super rich ore, but here in Lu Wei, only one or two grams of a ton of rock is not gold, because the element purity meter shows that the gold element enrichment of this gold mountain exceeds 99.9%.

"Such a mountain of gold, if it is moved to the earth, I am afraid it will directly cause a world war, right? But from now on, this mountain of gold belongs to me, hahahahaha. ”

Lu Wei laughed wildly, and his mood was extremely happy.

At this time, Le Ji changed, and behind a golden stone slope, a monster that had been covered in golden armor suddenly rushed out, brandishing a scythe-like front claw, and rushed straight towards him.

"What kind of monster is this?"

Lu Wei was slightly surprised. Hurriedly took out the ray gun from the space ring and shot at the golden armor monster.

The blue rays pierced through the golden armor monster's brain, destroying its thinking system, and the monster fell in front of him.

The on-board intelligent system analyzed: "Master, this is a monster that feeds on gold, and 80% of its body structure is composed of gold elements. You may have entered its territory and caused its displeasure. ”

"Gold-eating beasts?"

Lu Wei didn't expect this kind of monster to appear, there was a slight vibration on the ground, his face changed again, and many monsters rushed towards him.

"A large number of gold-eating beasts have been detected, and they will arrive in 20 seconds, please evacuate quickly." The intelligent system alerts.

Lu Wei hurriedly put the corpse of the gold-eating beast on the ground into the space ring, jumped into the cabin in two steps, and the drone blades fanned. Rising in the air, the golden slopes below were filled with dense gold-eating beasts, conservatively estimated to be at least 100,000 or more.

This has always made Lu Wei, who was a little embarrassed at this time, very unhappy, a good gold mountain has become the territory of gold-eating beasts, how can this be endured?

Be sure to save face.

The fleet landed on a nearby hill where there were no gold-eating beasts. Lu Wei first found a relatively flat place and inserted a metal locator. Then he carried the ray gun on his back and came to the edge of the gold mountain alone.

Aiming at a lone goldeater, pressing the trigger to activate, the blue light passed through the brain, and the goldeater fell.

Lu Wei went over and collected the corpse of the gold-eating beast.

The use of a ray gun requires an energy nucleus as a "warhead" and mental power as a "gunpowder". The energy core is enough, with Lu Wei's current mental power, if he doesn't rest in between, he can continue to shoot two hundred times.

After shooting more than a hundred gold-eating beasts by guerrilla warfare. After taking more than a dozen corpses, he couldn't stuff them, Lu Wei still wanted to kill more, and after more than a hundred shots, when his mental power was almost exhausted, he returned to the drone, made a mark of "Golden Mountain" on the map, and then left this place.

The process of exploring to the west lasted for more than 20 days, and Lu Wei discovered many kinds of mines, jade mountains, or gold mountains, among which there were seven or eight gold mountains, with small reserves of several thousand tons and large ones of hundreds of thousands of tons.

I have seen a lot, but Lu Wei is a little aesthetically fatigued, and his attention is on a lot of mineral resources that Kai pays attention to, such as black gold ore, platinum ore, purple gold ore, etc., these resources are not available on the earth, and the physical and chemical properties are extremely prominent.

"Master, there is a black gold vein in front of you, it is a super large bonanza, a tower defense base is placed here, and an additional 100,000 units of black gold elements can be supplied every day, it is recommended to set up a placement point."

"Oh, a super-sized bonanza?"

Lu Wei became interested, and looked down through the cockpit glass, not the black crystal mountain range in front of him, stretching for more than 300 kilometers and more than 20 kilometers wide, the whole body was bright and crystalline, obviously, the entire mountain range was made of black gold.

The control plane landed on the mountain range, like an ant standing on a loaf of bread, very small and negligible.

The black gold element is very strong, according to Kai's calculations, it should be about eight times that of tungsten gold, with high melting point, small density, excellent electromagnetic conductivity, and the physical characteristics of the whole machine 2186 plane, which can be compared with this element very least, but the content is also very low, very rare.

Walking on the Black Gold Mountain Range for a while, on the uneven ground, Lu Wei didn't find a piece of exposed black gold ore, all the black gold mines, all of which formed a whole with the mountain range under his feet, like a steel mold poured with molten iron.

After walking some distance, Lu Wei discovered a fault formed by geological activity - an inconspicuous crack about a meter long.

In this crack, Lu Wei's face was happy, and he saw five independent, solitary pieces of black gold ore lying inside, the large one, sixty centimeters in diameter, like a big pumpkin, and the small one, ten centimeters in diameter, oval, like an oversized orange.

He put all five pieces of black gold ore into the space ring.

After looking for this black gold mine, inserting a metal locator nearby, and the plane exploration that lasted for more than fifty days was almost over, Lu Wei, who had found 2,300 base car placement points, felt a little tired and impatient, and was ready to take a good rest.

On April 22, Earth time, Lu Wei, who was in the dust, returned to the tower defense base of the headquarters.

"Friend, I have successfully developed the base vehicle that you said can fly, and it can quickly reach the base vehicle placement point you designated in a short period of time and become a new tower defense base."

Kay reported.

Lu Wei looked at the base vehicle in the video that was boosted by a bottom rocket, and then gradually moved away under the pull of 10 "Transporter 2" drones with a load capacity of 100 tons, nodded and said, "Kai, you did a good job." ”

Lu Wei said again: "Kai, in the next period of time, I will come here less often, and I won't stay for long, and some matters that need to be dealt with will be entrusted to you, Kai." ”

Kai smiled and said, "Ok, friend, I wish you a good life." (To be continued......)
