More goods were opened in the mall, all of which were all kinds of materials, equipment, and weapons, and Lin Feng was dazzled.

Many materials require special processing equipment, such as a kind of super-hard, ultra-light, super anti-corrosion and high-temperature materials, to make it into the desired shape, it is necessary to use special equipment to match it, and the price is ridiculously high.

Taking this material as an example, the price of a ton is 8 million RMB, or 7.95 million cosmic coins, but its processing equipment costs 5.5 billion, which is enough to buy several large mines.

But the specific gravity of this material is only one-fifth of that of water, cut into a thickness of 0.1 mm, and 1 square meter is 40 grams, which is lighter than a mobile phone.

As for its use, it's simply not too much.

From mobile phone shells, anti-theft doors and windows, and body armor, to cars, ships, and even airplanes, artillery, tanks, spaceships, and space stations, as long as there are people, they can be used.

Lin Feng's car is estimated to have used similar materials, and last time he knocked several Humvees into shapeless, and he didn't see the slightest damage to it.

He put this supramolecular polymeric material into his collection, but the price was too expensive to buy for the time being.

As for those weapons, Lin Feng felt that he couldn't use them at all, so he wouldn't waste this money for the time being, after all, the price of weapons was the highest among all commodities. The cheapest is a super dagger, which is very sharp and can really sharpen iron like mud, and the price is 1.2 billion.

This thing is so dangerous that you can cut yourself in two if you don't pay attention.

So when he was too addicted, he began to try the seller function, and making money is his current job.

According to the instructions, if he wants to release the product in the Universe Mall, he must use a scanner, which does not need to be purchased, as long as he applies for it, it can be teleported to him through the space in time.

The scanner is like a bracelet that can be carried around, as long as its scattered beam is aimed at the goods that need to be scanned, the data can be obtained quickly, and the data information can be transmitted back to the mall's server in time for automatic verification.

The products that pass the review can be put on the shelves for sale, and the product introduction needs to be written by yourself, and the price must be drawn up by yourself.

As for the pricing standard, the mall gives the opinion that unless it is a specialty, or high-tech to the point that no competitor can price at will, it is recommended to increase the selling price by 10%~30% according to the local market.

Of course, ordinary commodities can also be priced at will, but the universe transaction follows the laws of the market, everyone is very smart, even 100 times smarter than the earthlings, and no one will be the wrongdoer.

More importantly, the quality must be excellent and the description must be true.

Once it is found that the seller has shoddy, cheating, concealing the truth, etc., the Universe Mall will immediately cancel all his qualifications and will never land on his planet.

With such severe punishment measures, we can ensure that the quality of the products is leveraged, so that everyone can buy with confidence and use comfortably, which is the service tenet of the universe mall.

Lin Feng took a box of facial masks from the shelves and scanned them with a scanner.

Soon the Marketplace interface returned with feedback: X-su Volcanic Mud Mask, native to the Andromeda Galaxy, is available for sale as a second-hand item.

It's so powerful, it's instantly recognizable.

Lin Feng looked left and right, and pointed the scanner at the laptop on the table: an outdated computer terminal that could provide simple number crunching functions and achieve data convergence through specific network protocols. If you need to sell, it is recommended to have all external devices in place.

Well, it's not bad, it's just that this laptop, which was the latest and highest configuration last year, was actually said to be a backward product.

Sure enough, people are more angry than people.

This kind of low-tech stuff is estimated to be bought even if it is put on the shelves, so it still needs to be considered in terms of specialties.

But what is the specialty of the earth?

This question is too difficult to answer, and Lin Feng has never been to another planet.

In the end, he came up with a way to search everything he could think of in the mall. As long as you can find a lot of them, they are definitely not specialty.

After a long time of trying, he finally found that in addition to Hongyun tea, there is a silk product that is actually more popular.

It is not this ordinary silk on the earth, but a kind of silk spit out by a starry sky silkworm. The toughness of this silk is so good that a single thread can withstand a weight of 100 kg.

In the mall, one kilogram of starry sky silk can be sold for 180,000 RMB, which shows its high quality and rarity.

The reason why it is so expensive is because the starry sky silkworm has a large appetite, is also very picky about food, and has a stubborn personality, if there is no favorite food, they would rather let themselves fall asleep until they starve to death.

Although the lifespan of a starry sky silkworm is only five years, it can spit out 1,500 silk balls and about 2,000 grams of silk in its lifetime, which can bring an average of 72,000 yuan per year.

Lin Feng decided to give it a try, there are so many plants on the earth, maybe there are things that the starry sky silkworm likes to eat? Just like Hongyun tea, it can't be grown on other planets, and it performs well on the earth.

The next day, the courier company delivered 10 adult starry sky silkworms to him.

Compared with ordinary mulberry silkworms, the starry sky silkworm is larger, thicker than the fingers, and about 10 centimeters in length.

Lin Feng had seen silkworm farming when he was a child, and as soon as he approached the place where silkworms were raised, he could hear a rustling sound, day and night, and a silkworm could eat about 1 catty of mulberry leaves in his lifetime.

The size of the starry sky silkworm is larger, and the silk production is more than 70 times more than that of ordinary silkworms, so it must be a bigger foodie.

Probably because there was no food, the guys were curled up there motionless, like a ring of transparent gel.

Hopefully they will be able to find food that will satisfy them.

Lin Feng immediately called Fan Lei and drove to the suburbs.

Now this season, the farmland in the suburbs is full of mulberry leaves, Lin Feng selected some relatively clean young leaves and put them in the box, but the starry sky silkworm didn't buy it at all, and didn't even open its eyes.

Then he picked more kinds of leaves, and even rice leaves were tried, but it still didn't work.

Fan Lei saw him picking leaves everywhere, and he also became curious.

"Wow, such a big silkworm?"

"New variety," Lin Feng said casually, "don't touch it with your hands, it's easy to die." ”

Silkworm raisers know that silkworms are very delicate creatures, and they must be disinfected every day, otherwise a large number of them will die.

"Why don't they eat anything?"

"I don't know, aren't you looking for something they like to eat?"

Fan Lei said: "Seeing that they are so fat, I estimate that they should be advanced, such as eating meat." ”

Lin Feng was too lazy to talk to him, but this reminded him.

He has been looking for it in the wild, maybe the starry sky silkworm grows so delicate and transparent, he really wants to eat some high-end goods?

So they immediately went back to the city and found a vegetable market.

Broccoli, peppers, radish, potatoes, green onions...... Neither.

Finally, I bought a handful of oily wheat vegetables at an old lady's stall, put the tender and pulpy leaves into the box, and then 10 big foodies woke up.

Stretching a long lazy waist, eyes smaller than sesame seeds began to glow green, and a few leaves were quickly gnawed clean, even the middle veins were gnawed off.

And after eating, the 10 little ones were still half-erect and looked around, looking like they were not full at all.

Lin Feng was overjoyed, it seemed that he had really found him.
