"It should be unrealistic to expect the Firearms mission to give 600 Doomsday Honor Points all at once."

"This task is exactly what I want."

Su Heng originally planned to come back at night to expand the safe house, but he didn't expect to be able to complete the task smoothly.

"Accept the mission!"

This task is relatively simple, there are three routes.

1 Consolidation is to increase the safety factor of the stone shelter.

2 Upgrade, upgrade the safe house to a more advanced shelter.

3. Expansion, expand the area of ​​the current shelter, and the extension must be at least the same level as the current shelter.

"Now my safe house is sufficient in all aspects. I don't know what the next disaster will be. Blind upgrades may be useless."

"I have a model of a safe house that I just captured, which I can use."

The third [expansion] route is the most cost-effective for Su Heng, as long as he collects 240 units of stone.

Su Heng opened the exchange and browsed around.

As of now, it has been the 10th day that everyone has been put into the apocalyptic world.

During this period, in addition to fighting hunger, intriguing psychological games on exchanges/channels, fighting alien beasts, and grabbing airdrops, people also experienced at least two disasters.

It is impossible to obtain supplies, and the people who guarantee their own survival are almost dead.

In other words, they were eliminated in the end times.

Natural selection, survival of the fittest.

The remaining people are all people with basic combat power/IQ/skills, and they have enough supplies in their hands to ensure their survival in the current world.

After the end of the "storm disaster and snow", the originally chaotic prices have basically ended.

Su Heng noticed that most of the people who exchanged 20ml and 50ml of pure water with him have survived to this day.

However, with pure water of this volume, it will be difficult to receive supplies and materials on exchanges in the future.

With the basic rewards issued by the system after the disaster, and the fact that those with extremely poor conditions have died, the current price of food and water is almost stable within a range that everyone can accept.

Material prices on the exchange rose uniformly.

The daily necessities of kerosene, fuel oil and coal have increased slightly.

Those who survived the two periodic disasters gradually realized the horror of the disaster and began to pay attention to the development of their own shelters.

The price of hard materials like wood, stone, and iron that can be used to upgrade shelters has risen to a special range for this reason.

At present, the mainstream upgrade direction of the public is the enhanced version of the wooden safe house.

There is also a fenced safe house made of polluted water mixed with plant fiber/chipped wood/stone.

This has led to the price of wood, which is several times higher than before.

Even the price of polluted water has risen considerably.

"Except for those who can't get wood, probably only local tyrants will buy wood on the exchange, which is too expensive."

【Seller: Wang Tingting】

[Items on the shelf: 1 antibiotic]

[Transaction Intention: 4500ml pure water/8kg any food]

[Remarks: You can change the water and food for the food that is opened in the treasure chest. If you use food to replace it, it should not be too dry, and there is no bargaining! 】

"Pinch, are you crazy about water?"

"An antibiotic needs 4500ml of pure water?"

"8kg of food is enough for me to eat for a month!"

"Sister Wang, can it be cheaper?"

"3000ml seconds!"

"Is 5kg negotiable?"

Medicines are currently very rare in the world, and they are a piece of cake on the exchange. Anyone who is sick or not will want to hoard some medicines in case of emergencies.

After all, the probability of being infected is too high, not afraid of 10,000, but just in case.

Although there was a lot of scolding from below, this trading post only stayed in Su Heng's line of sight for seven or eight seconds, and then it was taken off the shelf and photographed away, showing the preciousness of the medicine.

In addition, items including vitamin C, such as fruits and vegetables, are also hot commodities on exchanges.

【Seller: Li Xunhuan】

【Items on the shelf: 1000ml pure water】

【Intention to trade: 1000g of any fruit/2000g of vegetables/vitamin tablets】

[Remarks: You don’t have so many on hand, you can chat with me directly, it won’t make you suffer, don’t rot and worms! 】

"Boss, how much can you exchange for two sugar oranges?"

"Boss, how much can you exchange for half an apple? It's not very brittle, it's a little doughy, and it's rich in vitamins!"

"What about wild vegetables? I dug them in the tree pit and should be able to eat them."

"Ah yes yes yes, eat and send the landlord away?"

Su Heng browsed around and roughly understood the current price system.

He thought for a moment about what materials he should use, and what proportions would he need to quickly exchange for the stones he needed on the exchange?

"By the way, use silver spirit water!"

Silver Spirit Water is equivalent to the secret medicine in the game.

Drink 1ml, 10ml can't get buff at all, you need to drink at least 50ml each time to get buff blessing.

The buff time can be superimposed, for example, the buff time of each silver spirit water is 1 minute.

If you drink 100ml at a time, you can get a 2-minute buff.

Drink 150ml to get a 3-minute buff, and so on.

After deciding on the items and proportions to be listed, Su Heng took pictures with the Doomsday camera and sent out his trading post.

【Seller: Su Heng】

【Items on the shelf: 3000ml Silver Spirit Water】

【Intention to trade: 240 units of stone】

[Remarks: [Picture][Picture][Picture] Check the entry attributes for yourself. If you open it in the treasure box, UU Reading www.uukanshu.com will exchange 50ml of silver spirit water for every 4 units of stone. scold! 】

Trading posts with pictures quickly became popular on exchanges.

In addition, Su Heng's listed items are very special, and the number of views has increased by one million.

The number of comments below exploded directly, and Su Heng kept receiving comments that he couldn't even read it.

"Fuck me? What is this?"

"Recover physical strength at a moderate speed?"

"Slightly increase physical strength, speed, strength, intelligence, and spirit within 1 minute?"

"It's equivalent to giving people a buff? Is it a small stimulant?"

"Can this thing still be found in the treasure chest?"

"Boss, can I ask, what treasure chest did you open?"

"Bug item! Definitely a bug item!"

"I'm going, I want this thing, I can definitely get the airdrop yesterday!"

"Wait, are you still taking drugs?"

"Boss, I'll change it!"

The appearance of Yin Lingshui shocked the huge exchange, completely beyond Su Heng's expectations.

Many people didn't have stones on hand, but they did not hesitate to exchange them for stones on the exchange to trade Su Heng's silver spirit water.

Su Heng originally thought that the suspected point might just be a lot, but he didn't expect them to have none at all!

Silver Spirit Water appeared for the first time, and the discussion it caused was huge.

Su Heng did not expect such a situation to occur, and this was not his original intention.

Su Heng hurriedly operated the transaction and mailbox, quickly collected 240 units of stone, and then took down the transaction post.

"Has no one ever driven to Yin Lingshui before?"

Su Heng frowned, lost in thought.

"It's the only family?"
