In addition to the rat meat, in addition to the long thorns used to arrange the traps, there is also a chest full of long thorns, which can be used to make traps or weapons, and even arrows or sewing needles.

At least he'd tried the sewing needle, quite fine.

Then there are five bottles of rat blood, in fact, after these rat blood is coagulated, after boiling soup at high temperature, it has the effect of nourishing blood.

But this is rat blood, he is afraid that he will have symptoms such as diarrhea after drinking it, and after thinking about it, these rat blood can be traded.

After all, rat blood is a good thing for survivors who don't have food to eat.

Others, such as mineral water, sewing kits and unused threads, are all opened from the box, which are for him to survive and are not for sale.

Xu Shiying silently calculated in his heart, the items in his hand that could be traded and what could not be traded, and he suddenly had a bottom in his heart.

The rest of the chat is a lifeless moan, and in this unfamiliar environment, chatting may be the only entertainment for many people to relieve their fear and loneliness.

But he didn't have time for these entertainments.

The problem of survival has not been properly solved, and there is no time for entertainment.

After Xu Shiying muttered a few words, he turned the page to the trading page and found that there was already information about someone trading on it.

At a glance, food, stone and wood, these three items are currently the hottest best-selling items, and it can be said that as soon as they are put on the shelves, they are sold out.

No, as soon as I saw a transaction information exchanging wood for food, it was gone in the next second.

He didn't blindly put it on the shelves, after all, he didn't know much about the market, and no one bought things when they were expensive, and when they were sold cheaply, they lost money.

Observing the trading page like this, it took about ten minutes before Xu Shiying clicked on the operation button.

"A bottle of mineral water, rat blood, trade for twelve stones."

After the operation, Xu Shiying confirmed that the information was correct and clicked on the shelf.

Soon information about rat blood appeared on the trading page, and he even took pictures to ensure that Tong Su was not deceived and that the goods were genuine.

As soon as the item went online, a voice came.

Xu Shiying thought it was a successful transaction prompt, and looked down to see that it was a private message sent to him.

He clicked on the message.

"Dude, how about five stones, for a bottle of hedger blood? You should know that stones are hard currency nowadays, and it is hard to find them with one stone! ”

"It's hard to catch a hedgehog, ten stones, no less!"

"Dude, brother is bitter, eight stones, I will contact you often in the future, there are good things, brother, I will consider you as soon as possible!"

"Deal!"

After some haggling, he finally traded all five vials of rat blood for eight stones.

Five vials of rat blood were exchanged for 40 stones, and the next upgrade to the shelter required 50 stones, and he used five vials of rat blood for 40.

It was much more cost-effective than when he went out to carry stones.

After the transaction was successful, white light appeared in the green circle out of thin air, and as the white light dissipated, stones of different sizes appeared in the green circle.

Looking at these stones, a bright smile appeared on Xu Shiying's face.

Just then, a message popped up.

It was sent by a survivor named Zhuge Dali.

Zhuge Dali: "Brother, do you have meat?" 50 grams of meat, two trunks! ”

Xu Shiying's eyes narrowed slightly, he had never bubbled in the chat from beginning to end, even when he was trading with the person just now, he didn't say anything else except bargaining.

How did this man know that he had meat?

Suddenly, he seemed to understand what was going on.

Just as he observes the trading information, this person must also be paying attention to the trading information, and he has just traded five bottles of hedger blood, as long as people are not stupid, they can guess that there must be meat in the hands of the trader.

Since this person is willing to trade tree trunks, it means that he has a large number of tree trunks in his hands, and may have even upgraded the shelter.

He now needs 52 trunks to upgrade the shelter, if the number of trunks in his hand is sufficient.

Maybe we can upgrade the shelter tonight.

"30 grams of meat, two trunks!"

Xu Shiying thought about it and tapped on the "Survival Manual".

Somewhere in the world of global cataclysm.

In the cockpit of the excavator, a capable girl wearing a down jacket and eyes held the "Survival Manual" and looked at the information in the chat, the corners of her mouth turned up slightly.

"It seems that my guess is not wrong at all, this person has a lot of meat and can develop into a long-term stock!"

And the shelter behind her has obviously been upgraded, and has become a real shelter that can protect from the wind and rain, and is no longer the rough cabin that is like a piece of tissue paper and leaks the wind.

Even a large number of tree trunks and stones were stored in the green aperture, piled up as high as a hill.

If Xu Shiying could see it, he would be surprised, not only did they successfully upgrade their shelters, but they also accumulated enough materials for the next upgrade.

She can level up whenever she wants.

It's just that she didn't upgrade quickly, presumably she planned to use these materials to replace many things that she needed.

Zhuge leaned back vigorously and comfortably, with an excavator, she had an innate advantage in cutting down trees and stones.

That's the power of technology.

It's just that every time the excavator starts, the oil and electricity it needs to consume are huge, so the materials she collected did not rush to upgrade the shelter again, but exchanged the resources in her hands for any materials she needed.

It's the same as playing a game, the most important thing is to accumulate all kinds of materials and equipment at the beginning, if you don't have enough survival materials, even if you upgrade the level of the shelter to a higher level, without food and drinking water, it's useless.

She already has enough fresh water to drink, and it is no problem for a month or two, but there is a shortage of meat.

It is also strange to say, for example, she has not seen a relatively gentle beast like the three-eyed black rabbit, but she has seen a few wild wolves, and a few beasts that look like tigers but not tigers, if she hadn't been sitting in the excavator, maybe people would have confessed there.

And the beasts saw that they could not help these big iron bumps, and they all ran away and fled.

Although a lot of tree trunks, stones, and water resources were harvested, no meat was caught at all.

Through the analysis of the weather forecast in the "Survival Handbook", after a week, there will be a wide range of cooling, and the necessary meat and warm items are what she needs at present.

As for upgrading shelters, there is no hurry.

Zhuge Dali: "Then what kind of meat do you exchange for?" ”

Xu Shiying thought for a while and replied: "Hedger meat, this meat is very fresh, and the quality of the meat is no less than the texture of chicken, duck and fish, if you really want to trade, I can give you two pieces of roasted hedger meat for you to taste!" ”

"Rat meat, ......"

Zhuge vigorously saw the content of the reply, and frowned into Sichuan characters, even if she could excavate the excavator and recite pi for three thousand, but she really didn't like this thing.

It's just that she knows that it is not easy to fight wild beasts in the wild, and the environment here cannot be compared with that on the Blue Star.
