There is a faint mist shrouded in the mountains, and a nine-foot hanging coffin hangs high on the cliff wall, like a light veil, mysterious and strange.

The opposite mountain road is rugged and difficult, and the coffin is hung at a height of more than 100 meters, which is a very complex technical problem in terms of engineering technology, but the wisdom of the ancients cannot be underestimated.

Tombs like this cliff hanging coffin are a kind of burial method of the ancient Yi people, which has always been a research topic in the archaeological community.

It's just like Xu Linyuan exploring rare earth mineral resources, and the surrounding area is barren and populated, and this cliff hanging coffin is accidentally found between barren mountains and mountains, and the atmosphere is always a little weird.

After the Qingyuan found an open field and stopped there, Evil Lai reported: "Boss, it takes 13.6 hours to collect rare earth ore at the resource point here, is it collected proportionally, and the energy is extracted?" ”

"What is the energy extraction ratio of rare earth minerals here?" Boss Xu no longer thought about the hanging coffin, so he asked.

"The ratio of mineral elements contained in the rare earth ore here is relatively high, according to the proportion of energy extraction, 0.596% per ton can be extracted, according to the remaining 46.3% of the total energy reserves of the Qingyuan, only 102.7 tons are needed to make the total energy reserves of the Qingyuan reach the full value!" ”

Hearing that the proportion of energy extraction of this rare earth ore was so high, Xu Linyuan was taken aback, and said: "Then give priority to collection, after the resource warehouse is full, part of it will be extracted for energy, part of it will be purified by Gongming, and the other part will be filtered and refined through the filter bin, and it will be synthesized into industrial raw materials with adjustable surnames, so as to prepare for the ...... needed for the Qingyuan to upgrade the materials."

After Boss Xu gave the order very clearly and unambiguously, Evil Lai quickly began to execute, after transmitting the command to the robot, and opening the warehouse door where it was located, the robots quickly descended to the location of the resource point and began to collect.

The two booms of the Qingyuan also stretched out from the hull, and after automatically selecting a more suitable landing point, the boom easily drilled through the hard rock formation to reach the area where the rare earth minerals are located.

"The collection arm has reached the target location and is about to start the collection ......"

After a burst of electronic synthesis sounds, a soft 'boom' sound was heard, and the main gathering arm of the Qingyuan began to work with maximum efficiency in the rare earth mineral area, transporting the collected rare earth minerals to the resource warehouse.

And those robots, with the cooperation of the other collection arm of the Qingyuan, after opening several collection channels, also began to collect with maximum efficiency.

He issued an order to Gongmei, when those rare earth minerals continue to enter the resource warehouse, Gongmei will transfer a part of it to the filter bin according to the requirements of the order, remove impurities, first purify the rare earth mineral elements, and then decompose the other part, and synthesize the purest raw materials that can be reconciled, so as to store them in the filter bin at a fixed point.

In the intense progress of the collection work, Boss Xu was idle, of course he had no interest in studying the cliff hanging coffin, but called up some rare earth data from the database for reference.

Rare earth is a group of new functional materials with a variety of special surnames such as electricity, magnetism, light, and biology at the same time.

It is also an important basic material for high-tech fields such as information technology, biotechnology, and energy technology, as well as for national defense construction, and also plays an important role in transforming certain traditional industries, such as agriculture, chemical industry, and building materials.

Rare earth has a wide range of uses, and there are many kinds of functional materials that can use rare earths, which are known as industrial "gold", and greatly improve the tactical ability of steel, aluminum alloy, magnesium alloy and titanium alloy used to manufacture tanks, aircraft and missiles. Moreover, rare earth is also a high-tech lubricant for electronics, lasers, nuclear industry, superconductivity and many other high-tech lubricants, which can be said to have many benefits, and is an industrial material with a strong fusion surname.

Xu Linyuan checked these materials, he originally wanted to integrate this rare earth material into his biological alloy, in addition to upgrading the Qingyuan, whether to introduce this resource into his metal strategic layout.

At present, his development plan has just started, currently only owns an iron mine, if you want to continue to expand, you have to gather a lot of capital, he plans to take the road of annexation and expansion, some small resource enterprises to eat small fish to take down, get more resources, and so on after the mining company grows, and then continue to acquire and expand, so that after the snowball rolls down, and then enter the foreign country...... Just when Xu Linyuan was contemplating the development plan of the mining company, at this time, Evil Lai suddenly reported: "Boss, the intelligent system has detected that there are three humans on the cliff wall in front of him who are carrying out activities, and it is very likely that the Qingyuan will be found, is it camouflaged and concealed?" ”

As soon as he heard this, Xu Linyuan suddenly came back to his senses and said, "Cut the monitoring screen over, I'll take a look!" ”

Soon, Evil Lai cut the surveillance footage, and saw that on the mountain road on the opposite cliff, there were three people climbing, and the things they were carrying were some tomb robbing tools, obviously a group of tomb robbers, not some archaeologists, obviously going for those hanging coffins.

However, Xu Linyuan is too lazy to care about these idle things, without these tomb robbers, how can there be a thriving cultural antique market, although some antiques are now said to be family heirlooms, or acquisitions, but it is just a disguise, in fact, they still rob tombs, and after circulating in the market for a period of time, they can be traded and bought in a straightforward manner.

"Carry out light simulation visual camouflage on the Qingyuan, but the movements of these people are monitored with a little monitoring, so as not to delay the progress of the collection......"

After Evil Lai carried out the order, Xu Linyuan continued to look through the materials and supplement some knowledge.

It's daytime now, and it takes about 13.8 hours for Qingyuan to collect these rare earth resources, which means that by about early morning, the collection work can be roughly completed.

…… A few more hours passed, and it was already afternoon.

The collection of the Qingyuan was still being carried out in an orderly manner, and Xu Linyuan looked at the information in the lounge for most of the day, and he was also a little confused, and he had been napping.

Rumble!

Suddenly, a loud noise came, alarming Xu Linyuan, who was napping.

Xu Linyuan suddenly woke up, and when he left the lounge, he asked, "What's going on?" ”

"Boss, when three humans were active on the cliff in front, a hanging coffin accidentally fell into the river, and the sound was loud, which may have alarmed the minority tribes behind the mountains in front!"

Roar, roar, roar!

At this moment, Xu Linyuan heard a roar from the surveillance, which sounded like a roar that found the enemy gathering, so he immediately asked the evil to expand the monitoring range to about ten kilometers, and found that dozens of green dots that were moving constantly were coming in this direction along the mountain road.

Looking at those green dots, they should all be people from ethnic minority tribes, although the surveillance screen can't see the specific situation, but the signs on the small map are very clear, they are hurrying along the mountain in front of them in the direction of the hanging coffin.

Xu Linyuan frowned, and said hatefully: "These tomb robbers are really not successful enough, and they are more than defeated!" ”

As he was talking, he said again: "Boss, these tomb robbers are fleeing from our side......"

Xu Linyuan turned the surveillance screen, and found that the three tomb robbers were a little panicked after discovering that they had alarmed the minority tribes, they used ropes to tie them up at a high place, and shot them with hook guns on a very thick tree that was only five meters wide on the opposite side of the mountain, and they hung it up with pulleys, as if crossing the river with iron cables, and quickly slid over to this side.

Seeing this situation, if those tomb robbers were allowed to come to the Qingyuan, the Qingyuan would be exposed, and Xu Linyuan asked hatefully: "How many rare earth ores has the Qingyuan collected so far?" ”

"Boss, at present, the Qingyuan has been collecting for a total of 6 hours, collecting 994 tons of rare earth ore, 494 tons of storage in the current warehouse, and 190 tons of synthetic raw materials are used in the filter bin for purification of mineral elements, as well as synthetic raw materials, and 310 tons of mineral elements to be purified, as well as synthetic industrial raw materials......"

"Can that meet the needs of this Qingyuan upgrade?"

Evil comes; "Satisfied!"

"Okay, since you've been disturbed by these tomb robbers, let's evacuate this place and go to Panshi to detect magnetite and titanium ore after removing the disguise!"

Xu Linyuan saw that half of the rare earths had not been mined, and when he heard that the needs of the Qingyuan had been met, he no longer cherished the remaining rare earth mines, and directly issued an order to evacuate.

After receiving the order, Evil Lai quickly asked the robot to quickly return to the Abyss with half of the collected resources.

After the Abyss closed the door and retrieved the two main gathering arms, Evil Lai activated the Abyss, and the light camouflage was lifted when the Abyss was activated.

Roar, roar, roar!

At this moment, there were suddenly many ethnic tribes like natives on the mountain, they took bows and arrows, and when they stood on the other side of the mountain and saw that the hanging coffins on the cliff were gone, they were all angry, and they roared loudly, and saw the tomb robbers fleeing towards the slope on the other side of the mountain, and a large truck farther away, so they also slid over with ropes.

Some were even able to jump over the five-meter-wide gap and chase after the few grave robbers who were running quickly.

The grave robbers had only run for a while when they spotted a large truck on the rugged hill slope ahead.

A young man looked a little shocked, his eyes widened, and he shouted as he ran: "Mom, Lao Tzu shouldn't be a hell, we saw nothing here just now, how could a big car appear out of thin air and drive on the hillside, is this still a car that is numb, this kind of ramp can also be driven?" ”

A middle-aged man running next to him said thoughtfully: "This car has a strange ......"
