The Lingering Stone is a spell item that records scenery like a video camera, but it is recorded in a completely different way than a camera on Earth.

Because, its scene recording is not dead, anything that happens within a range will be recorded, and there is no place where the lens can't see.

It's the same way it is played.

Watching the recorded scene is equivalent to putting yourself in the image of the time, and you can also move freely inside the scene, and the picture you see at different points is from different perspectives, which is a real recreation of the scene.

The so-called 3D movies on the earth are more than eight streets worse than the picture of the Shadow Stone.

The production of the Shadow Stone is not too difficult, and in the Cloud Hidden Sect, the refining room craftsmen who have cultivated at the dawn stage and above can basically make it.

The main reason for the rarity of the shadow stone is the rarity of the two main materials, one is the space stone, and the other is the colorful crystal.

The space stone, also known as the "boundary stone", is the main material for making space storage items, and the boundary stone is already scarce and precious, if you have to choose one or the other, any head of power in his right mind will choose to use it for refining storage items.

Colorful crystal is a relatively rare ore, a rare associated ore of white crystal, spontaneous colorful light, is an extremely expensive ornament, of course, compared to the priceless space stone, even in the market of mortal cities, you can occasionally see the figure of colorful crystal.

In Wei Yuning's view, the Lingering Stone represents the pinnacle of magic weapon technology in the entertainment industry of the Spirit Beast World, and the only regret is that it has not been applied.

With experience of living on Earth, he had many bold ideas and plans after seeing the Shadow Stone for the first time.

And as the first step of the plan, it is to acquire space stones and colorful crystals.

In the eyes of the Yunyin Sect, these actions of the Qing Demon are incomprehensible, but how do they know that behind these behaviors is a kind of remembrance of Wei Yuning's life on the earth, and also, this is a very profitable business.

For the acquisition of the space stone, due to financial limitations, Wei Yuning can only do what he can, but for the colorful crystal, he is definitely going all out.

In addition to these two things, he has more purchase lists, all of which are things with special uses.

The cultivators were all human spirits, Wei Yuning never planned to buy colorful crystals or space stones from them, and his main cooperation object was mortals.

In the hands of mortals, there are not only colorful crystals, but also space stones.

The main source of space stones is the outer walls of various worlds, and only the truly large Immortal Sect sects have the strength to mine them.

The production of space stones is actually not low, in the entire Great Yuan Primal Realm, in addition to the various living worlds, there are also many ownerless worlds and desolate worlds, but the number of space stones lost to small and medium-sized worlds is much less.

In addition to this, there is another source of space stones, and that is meteorites.

Meteorites pass through the outer walls of the world when they enter each world, and if they are large and hard, they have a certain chance of carrying some space stones to the ground when they pass through the outer walls.

These beautiful stones generally flow into the hands of the great forces of mortals, and then through various channels, they eventually converge into the hands of cultivators who really need them.

Wei Yuning had just entered a big sect like the Yunyin Sect when he came to this world, and at first he felt that cultivators seemed to be everywhere, but then he slowly realized that in the spirit beast world, the proportion of cultivators was actually very low.

There are no more than three reasons, one is limited by qualifications, the second is limited by chance, and the third is limited by resources.

For ordinary mortals in the spirit beast world, all cultivation sects, no matter how big or small, are the immortal sects in their mouths.

The cultivators who knew a little magic were the immortals in their mouths, and most of the immortals in their mouths were just miscellaneous disciples who had not yet built a foundation in the Yunyin Sect.

It can be seen that the things in the immortal gate are heavy in the eyes of mortals.

And Wei Yuning took advantage of this to do business with mortal merchants.

Wei Yuning didn't have much else, there were many low-level pills and low-level magic weapons, these were exactly what mortals needed.

Whenever a mortal merchant came to the Secret Medicine Pavilion to buy something, he would be told by the clerk that he could exchange "immortal medicine" and "immortal weapon" through colorful crystals or space stones.

After the baptism of the earth's commercial civilization, the things Wei Yuning provided were basically selling points of longevity and rejuvenation, which were the things that mortals cared about the most.

Necklaces, headdresses, earrings, bracelets, and other accessories that come with their own Soul Gathering Circle can add at least another twenty years to the life of mortals with an average age of fifty.

And a basic pill like Qingyun Dan, which discharges impurities from the body, is even more popular with mortal businessmen.

Not to mention the health tea series of health products provided by Hongle, the effect is amazingly good.

What's more, the Secret Medicine Pavilion also has the main product of Moon Pig Seasoning.

Therefore, although the opening time of the Secret Medicine Pavilion is not long, its reputation is not small, and the potential customers have been growing rapidly.

By word of mouth, not only mortal merchants, but even among the monks, they also knew that the Secret Medicine Pavilion was willing to pay a high price for space stones and colorful crystals, and more importantly, they also had the famous "Ten Miles of Incense" as an exchange.

Mixed with a variety of spices, the three moonworms make three bottles of top, six fine, twelve medium and twenty-four bottles of universal cooking accessories.

Each first-class excipient not only halved the content of the moon pig, but also doubled the number of bottles, and by the end of the pack, the content of the moon pig was almost invisible.

"It's too profitable!" Even Wei Yuning, who is very persistent in making money, is a little guilty.

From the point of view of cost performance, Pratt & Whitney is actually not affordable at all, but because of its low price, it is the most popular.

Of course, the various newly developed ingredients that Wei Yuning mixed in also contributed to it, although their taste is not as good as that of Yuezhi, but after mixing, they also have a unique flavor, and they are added to the food casually, which is much more delicious than the meals in the Zongmen canteen.

Taking the finished products with him, Wei Yuning left the Wind Lotus Garden and headed to the Secret Medicine Pavilion.

There were still a few shops away from the Secret Medicine Pavilion, and Wei Yuning heard a noise coming from inside.

"Since I can afford it, why don't you sell it to me! Space stones, colorful crystals, spirit stones, white crystals, what do you want, I have what, can't you do this?"

Listening to the voice, it was a young woman, but the arrogance in her tone was ashamed even if she was a true immortal.

White crystal is also a good thing in Wei Yuning's eyes, it is a substitute for glass in this world, it is very widely used, although it is not a scarce product, but it is also rare, Wei Yuning also added it to the acquisition list, but the priority is much lower.

"Girl, it's really not good, these things have already been booked! If you want to buy them, you can only wait!" was Haiyan's voice.

"I can't wait, grandmother is tomorrow's birthday, since double the price can't work, I can always pay three times, right? If you dare to shirk it again, I will smash your store today!"

Wei Yuning's eyes lit up, this is a big customer, and it is estimated that the only thing that can make customers purchase a lot of money is cooking accessories, and he has it in his hand.

Thinking of this, Wei Yuning didn't arrive, so he came first: "Senior Sister Haiyan, since the customer is so sincere, let's sell it to her at three times the price!"
