Looking at the six billion-plus contribution value on the account, a string of extremely long numbers, Xia Bo frowned.

He is not unhappy, on the contrary, he is very happy.

The reason for frowning is obvious.

The main reason for the loss is the quality upgrade in the resource upgrade system.

The price of the same product is 30 million, and the recycling price is 15 million.

If the quantity is upgraded, as long as there are more than two pieces, then this time the order is basically not a loss.

On the contrary, if it is quality improvement, it will lose money. After the quality is improved, the recycling price is only 20 million yuan, or a little more.

As for the possibility of exceeding 30 million, it is very low.

"So the upgrade of the resource upgrade system needs to be upgraded for the quantity, but any upgrade in quality will reduce the speed of brushing the contribution value."

Xia Bo thought in his heart, combined with his own journey, he now has a general understanding of the use of the resource upgrade system.

The resource upgrade system is aimed at some small objects, and the quantity upgrade is particularly prominent.

This can be seen when he uses professional medals, car fragments, food and water.

In terms of quality upgrades, there are equipment on one side, such as the butcher Xia Bo’s hatchet, magic armor, sophisticated boots, and magic scissors.

"So in other words, the probability of upgrading the quantity of food is relatively large, and the probability of upgrading the quality of equipment is relatively large."

After a little thought, Xia Bo understood. In fact, if you are careful, you can see it.

Of course, the quality of food will also be improved, and the most common thing is that both quality and quantity are improved at the same time.

Especially for water resources, bread, and fuel.

At the beginning, he saw the power of the resource upgrade system, but later he came into contact with more and more high-end things, so when the quality and quantity were improved together, it was much less.

"So my idea is wrong, it's not a high-end thing, the speed of brushing the contribution value is fast!"

Xia Bo's eyes flickered, and he had a clear idea in his heart. He clicked on the food category, and then chose the most familiar, that is, sarcoma, which is a piece of meat in an unknown organism, not a tumor. The rules are named, and he also sees it. Don't understand.

The taste of this piece of meat is very unique to the alien food race, but it is obviously impossible for him to eat it if he is used to eating the food on the earth.

[Sarcoma: 100 contribution value]

[Introduction: Food for hunger! 】

To put it simply, Xia Bo glanced at his contribution value, which was more than 6 billion. It would be enough to exchange 6 million copies for a sarcoma, and the size of the sarcoma was no more than a palm.

In order to ensure that he has enough space, he waved his hand and directly spent 2 billion to buy a space the size of a football field.

After the resource upgrade system upgrade, the space has doubled.

And the waving price is only 2.5 billion, and only earns 500 million at a time. If you buy all of them, you may not always earn 500 million every time.

Xia Bo still understands the probability of the resource upgrade system.

After the exchange, there was still more than 4 billion contribution points left. He directly exchanged more than 4 million sarcomas and stuffed them into the space. Over 4 million copies of sarcoma seem to be a lot, but stuffed into this space is just like a hill. Pile of meat.

Xia Bo looked at the pile of meat in the space, and didn't have much appetite.

Then came the upgrade.

The consciousness sank into the space and began the journey of upgrading.

[Ding! Congratulations on the successful upgrade of the host, sarcoma*1 upgraded to hardcover sarcoma*8! 】

[Ding! Congratulations on the successful upgrade of the host. Sarcoma*1 has been upgraded to fried sarcoma*7! 】

[Ding! Congratulations on the successful upgrade of the host. Sarcoma*1 has been upgraded to charcoal barbecue tumor*11! 】

[Ding...]

This kind of upgrade method is actually quite fast, after all, the idea is swept away, and the blockbuster can be upgraded in an instant.

It looks like more than four million, the same upgrade is very slow, but under the idea, the speed is very fast.

In six minutes, he had upgraded more than 1.5 million sarcomas.

And the sarcoma that you piled up on the mountain originally covered half of the space.

The upgrade continues.

Soon, the upgrade was completed, and sarcomas in the entire space covered the ground.

During this upgrade process, some sarcomas have been upgraded with more than one hundred copies, and the quality of sarcomas has also improved.

What hardcover, char-grilled, deep-fried, dipping sauce, smoked...there are too many types, even Xia Bo thinks that these sarcomas can be eaten by themselves.

Xia Bo took out a hardcover sarcoma and began to estimate.

[Evaluation of 75 contribution value! 】

[Evaluation of one hundred contribution value! 】

[Evaluation of one hundred contribution value! 】

...

I chose a few more familiar types, and Xia Bo valued it at a considerable price.

So the next step is the overall valuation.

Xia Bo directly took off the bracelet of the space ontology and put it on the valuation.

[Evaluation of 57.3 billion, 5,339,809 contribution value! 】

Contributions are zero or all!

"Sure enough! My idea is correct!"

Xia Bo’s eyes were shining brightly, and he immediately chose to exchange. The account balance directly changed from six contribution values ​​to 57.3 billion contribution values.

After finding the trick, the speed of earning contribution points soon increased a lot!

Xia Bo looked bright and continued to operate.

After all, this doesn't require any skill. For a space bracelet, all the remaining money is to buy sarcoma. After some operation, it took nearly an hour.

During this period of time, the Valkyrie outside was idle, sitting on the side and waiting quietly, without the slightest irritation, he knew how strong the temptation of the commodities in the exchange on the pillar was.

Without concealing it, if the strongest materials above can be exchanged, I'm afraid it will be able to dominate the entire town.

"Brother Xia must have squinted his eyes by the merchandise above, thinking that..."

Valkyrie recalled when he first came to the base, especially when he saw the goods on the pillars, he stayed inside for a full day, and ordered all the large and small goods inside. UU reading www. uukanshu.cOM

He saw this exchange system for the first time after entering the highway.

It is completely different from the rules of Survival on the Highway.

The rule of survival on the road is that the acquisition of materials depends on a probability, which is equivalent to looking at the face.

But here, all the materials are listed, as long as you have contribution value, you can redeem the commodities above that you can redeem.

It's a pity that for so long, I can only bear the contribution value of over 10,000, and can only redeem some life-saving things.

Skills are all auxiliary skills, and even the lowest of offensive skills is a contribution value of over 10,000, not to mention those millions, tens of millions, or even billions or tens of billions.

Those skills are mostly magic skills.

"Huh? Come out so soon?"

While thinking about it, Valkyrie suddenly saw Xia Bo come out from inside, and couldn't help scratching his head. He just said that he was fascinated by the merchandise inside, but he didn't expect to come out so soon.
