Bang, clang, clang.

The excavator worked with smoke, constantly shoveling up yellow and black dirt. The site is located next to the cement platform of the martyrs' cemetery, and the excavator can't dig the cement, so Zhou Yan chose the mud floor.

This should be the foot of the original Dashu Mountain, but the turf and trees have already withered, and the plants around the entire black magnetic world have been strongly disturbed by the magnetic field and completely died.

Zhou Yan guessed that there was a secret buried at the junction of the black magnetic world and the earth.

He just dug and dug here desperately.

As a person with a somewhat stubborn personality, Zhou Yan has always made a good decision, and he will never give up easily. The ordinary soil is soft compared to the black soil, and the excavator's operation efficiency has been greatly improved, and his skills have gradually become more proficient and more efficient.

Half an hour later, a two-meter-deep crater appeared.

The pit is excavated against the black soil boundary line, so most of the soil excavated is ordinary yellow-brown soil, but it will also bring out a small amount of black soil, as well as a mixture of black and yellow-brown soil.

Zhou Yan got out of the car.

Activating the micron robot in the left-handed recycling bin, the six-pointed star pattern swept around the dirt, and still no signs of the presence of the four substances were detected.

"Am I still wrong in my guess?"

Slightly shaken, she was quickly left behind and continued to dig a pit.

When he dug to a depth of two meters and a half, the black soil finally changed in his vision, the color was still black, but there was a white trace in it.

Smack.

Zhou Yan jumped from the cab of the excavator and ran towards the white trace, and when he came to the front, he found that the white trace was a substance similar to slime, which penetrated into the black soil. He turned the recycle bin on and aimed it at the white slime, looking forward to it.

Focus your eyes on the retina light screen of the left eyeball and the micron robot of the left-handed recycle station, and keep an eye out for new prompts at any time.

He suppressed his emotions and didn't expect much, and this action had been repeated many times, and each time it was disappointment.

But a second later.

Surprises abound.

- "Detection of the left-hand recycling station within the micron robot collection range, there is a Ψ variety ore, is it collected?" ”

"Gather!"

Zhou Yan held back his excitement and gave an order.

The six-pointed star pattern is shining, and the white mucus on the palm of the hand quickly evaporates and disappears. The recycling station in the palm of the left hand, the collection ability cannot be explained, it seems to be a similar way to take things in the air, resources within ten centimeters can be absorbed and collected in the air, and you can't see how it is absorbed at all.

No superficial contact is required.

"It's definitely high-tech."

- "Collecting...... Currently, the number of collections is insufficient to support the application...... Collecting......"

In a few seconds, the white mucus within ten centimeters was all absorbed. Zhou Yan himself took the shovel and began to dig along the white traces, and after digging a few shovels, the entire white slime had been dug out.

When I touched it, the white mucus was not sticky, like a kind of snot mud used to make toys, which looked a little disgusting, but in fact it was not dirty at all, very pure.

Shaking the soil off, the complete image of the white slime suddenly fell into Zhou Yan's hands.

It can be seen with the naked eye that the white mucus slowly contracted, and then in Zhou Yan's hand, it contracted into a trembling white transparent ball.

Pull it, and it can be pulled into a puddle of white slime, but it is difficult to tear *** kraft candy and be strong, as soon as you let go, you start to slowly shrink again.

Shrink into a ball, round and round.

I don't know, I thought Zhou Yan was holding a slime.

"Let's call you Variety."

Smack.

Pulling out the plastic bag in his pocket, Zhou Yan put the variety ball into it, carried it back to the cab, and continued to drive the excavator, he had to hurry up and dig deeper.

If there is a Variety Ball, there will be a second Variety Ball.

After a while, a new touch of white appeared, and Zhou Yan didn't get out of the car this time, but directly shoveled the Variety Ball to the side and continued to dig. However, after digging a few shovels, when digging to a depth of three meters and five meters, there were no more variety balls. Zhou Yan frowned slightly and began to dig horizontally.

Sure enough, on the line of 2.5 to 2.8 meters, two more variety balls were dug up that penetrated into the black soil layer.

By the time the sky was about to get dark, Zhou Yan had already dug up twelve variety balls.

All of them were dug on the line of 2.5 to 2.8 meters, and along the boundary between the black magnetic world and the earth, they dug a distance of about 20 meters.

"It's getting dark, it's not safe to spend the night outside, there's still work to be done at the camp, go back and continue tomorrow." Zhou Yan didn't drag mud and water, directly carried the full variety ball, returned to the big truck, and drove away from the black magnetic world.

On the way, he absorbed eleven of them, leaving only one, and went back to the lab to make samples.

Let the experts take a closer look at what exactly the substance is in the Psi Variant Mine.

The retinal light screen did not show how much Puxi Baixin Mine he had absorbed, and he himself felt that it was about 25 kilograms, which was far from the application value of one ton.

"A variety ball is about two to three pounds, and I have to absorb at least seven or eight hundred variety balls to make up a ton of weight, which is not an easy job...... Tomorrow, do you want to mobilize the survivors of the camp to help me mine the Variety Orb...... I probably don't say it, and the professors in the lab will ask for it, but how do I keep the ball for myself? ”

Zhou Yan worked for nearly three hours in the afternoon before he dug up twelve varietyballs, seven or eight hundred were enough for him to dig for a month.

But the camp has five days to go, and it will be moved.

When the time comes, if Zhou Yan leaves, he can only find a new world and then mine the Puxi Variety Mine; Otherwise, you have to stay alone and mine alone.

"Maybe I'm thinking a little complicated, and when the Variety Ball is mined to the camp, I'll just look for an opportunity to absorb it. When you're on the move, even if you're discovered, it's not a big deal...... Or can I just talk to Professor Wu Hui and say that this kind of thing can help me evolve? ”

Boldness of execution stems from superb skill.

If Zhou Yan was just an ordinary person, he wouldn't dare to do anything out of the ordinary casually, lest he be caught as a guinea pig for dissection and research.

But as the strongest combat force in the Emerald Lake camp, he is also one of the top managers of the camp, so why be afraid.

And the reason that attracted him to desperately want to get enough Puxi Baixin Mine was the transformation sequence of the gene-level operation group, and the metal transformation of various body tissues in it all needed Puxi Baixin Mine as a resource. The fragile body is transformed into metal tissue, and you can imagine how much the life-saving ability has improved.

Sometimes Zhou Yan wanted to try it and shot himself in the head.

See if the Chogokin skull Lv1 can block bullets.

Just thinking about it, of course.

……

Today is a fruitful one.

It's a pity that the source of Sigma's energy crystallization has not been found - of course, the clue is already there, and the discovery of the Phusi Variety Ore proves that these four substances are all derived from the changes caused by the formation of another world. As long as you follow the junction, you will eventually be able to find it.

"Now there are 2 kilograms of Sigma Energy Crystals, don't wait, produce!"

His eyes flickered for a moment, and he decided which two types of aircraft to produce—the Ear Wheel Radar Fleet Lv1, and the right-hand processing plant microrobot Lv1.
