With billions of supplies, it thrived in the 1970s

Even before it is developed, you have the opportunity to trade

"We have been trading for such a long time. After receiving the crystal core you sent me, I also tried to deal with the impurities in it, and the effect was very good.

It involves techniques and some things unique to the plane. I can't directly trade the technology to you, but I can help you deal with the impurities in the crystal core and make it impure. And you need to pay a certain number of crystal cores as compensation."

"Can you let me see the processed crystal core first?"

"No problem, everything is ready. I will send you three crystals at the trading desk, you can check them. I suggest the most convenient and quickest verification method, you can directly put it in the recycling section of the [Plane Mall] and see the recycling price given by the mall."

When the crystal core at the trading desk disappeared, I didn't know what verification method the other party used, and quickly fed back the verification results and their needs:"It is indeed a crystal core without impurities, we can absorb it directly. Then please tell me the cost of removing impurities."

"Before I talk about this, I want to ask, I have also seen the crystal core, and it should be divided into levels, right?"

"Yes, we distinguish them by size and color. The first one is level one, and so on."

"Well, there are several types of purification fees, you can choose when the time comes. For every 1,000 crystal cores purified, there are six ways to collect: 400 first-level crystal cores, 300 second-level crystal cores, 230 third-level crystal cores, 150 fourth-level crystal cores, 60 fifth-level crystal cores, and the rest are higher according to actual conditions. The properties are still the same as we mentioned before."

"No problem, but how long will it take to purify 10,000 crystal cores?"

"Half an hour"

"Great, I will purify 30,000 pieces first, and when the transaction comes back, I will put them directly on the trading platform according to the price you proposed, and I will definitely guarantee the quantity and quality."

"There are also several kinds of liquid medicine and pills. I don't know if you need them. But these can only be exchanged for several crystal cores with specific properties."

After that, she recommended the three kinds of liquid medicine and bigu pills recommended by the interstellar plane in turn. Just like the interstellar plane, she first gave out 10ml of each test package and two bigu pills for trial use.

When the people from the apocalyptic plane also went to verify, Miss Jun led Xiaobai to quickly soak 30,000 crystal cores in spiritual spring water and dry them. Put them on the trading table, and when they see it, they will automatically complete the transaction.

While making winter quilts with cotton and down in the room, Xiaobai's shouting has been heard:"Sister, someone from the plane system has sent a message."

Seeing the expected reply:"God Jun, your liquid medicine is so effective for interstellar people. How do we trade?"

"The points for the medicinal liquid are relatively expensive, so you can consider the quantity you need. The normal specification of each medicinal liquid is 30ml, each bottle of Spirit Liquid has 8,000 points, each bottle of Repair Liquid has 8,000 points, and each bottle of Quenching Liquid has 5,000 points. The quantity is capped at 300 bottles of each type each time, and the transaction cycle is once every half a month."

I thought the person on the other side would think the price is expensive and be a little hesitant. Unexpectedly, Odysson Machir kept replying in seconds:"Okay, once every half a month, 300 bottles of each type."

I couldn't help but ask out of curiosity:"Don't you think it's too expensive?"

"Hehe, in the face of health and strength, this price is completely acceptable. The interstellar people are also constantly troubled by the Zerg, and the restoration of strength and genetic collapse are all our highest pursuits. Including the food we have been trading before, it has also attracted the attention of the royal family. My family has even been praised by His Majesty."

From the tone of the conversation, it can be heard that he is really satisfied with this transaction:"Okay, I will call my assistant to trade for you in the future, once every half a month. Do you need to trade today?"

"Is that okay? Then I want 300 bottles of each."

Looking at the latest 6.3 million points, plus the remaining points after the last upgrade,

"Xiaobai, upgrade!!!"

This time the space was just like the first time, and there was a huge movement again.

"Are there any big changes?"

"Sister, there is a top-grade spirit stone mine connected to the low-grade spirit stone mine. It’s top-grade, top-grade. Seeing that she was so excited that she was shouting the last"ah", she was splitting her legs. She looked at Xiao Bai with surprise.

"Ahem, sister, I'm just a little excited."

"Let me guess, this top-grade spirit stone mine must be very powerful, right?"

"It's not just amazing, the conversion of spirit stones is a hundred times. 1 top-grade spirit stone is equal to 100 upper-grade spirit stones, 1 upper-grade spirit stone is equal to 100 middle-grade spirit stones, and 1 middle-grade spirit stone is equal to 100 lower-grade spirit stones."Now, sister, do you know how rich you are?"

Jun Qingqing, who was already numb with shock, could only nod blankly, nod, and nod again.

At the same time, the plane system was upgraded to a high level. The corresponding immortal cultivation plane was also opened.

Before I had time to go back to make quilts, the news of the doomsday plane came.

In the end, the transaction was to exchange 1 space or spirit system crystal core for a bigu pill.

The first-grade pill used the first-grade crystal core, the second-grade pill used the second-grade crystal core, and so on to the fifth-grade pill.

Yes, Jun Qingqing's alchemy level has steadily reached the fifth-grade some time ago.

For the liquid medicine, it also only needs the spirit and space system crystal cores.

Each bottle contains 150 first-grade crystal cores, 120 second-grade crystal cores, 90 third-grade crystal cores, 55 fourth-grade crystal cores, and 30 fifth-grade crystal cores.
