"But what to change... Well, by the way, my house should be upgraded. The first-level territory is too narrow and narrow, and it can't accommodate my gains at all."

Colin exclaimed the message of his dilapidated wooden house.

[Level 1 Territory: It can block gray fog, can be easily synthesized, but cannot be moved and cannot be included in the backpack.]

After clicking on the upgrade option below, four upgraded branches appear there.

[Underground Fortress] [Hanging City] [Trolley] [Second Territory].

The above is only an introduction to its functions and does not inform how much material is needed. If the materials are insufficient, the upgrade will only reply that it cannot be upgraded.

But through the prompt, Colin can directly obtain the corresponding material information without requiring drawings.

"The first-level underground fortress requires three thousand parts of iron, two thousand parts of clay, one thousand parts of gravel, two thousand parts of stone, one thousand parts of wood, two hundred parts of thorns of suffering, one hundred foggy spots...well..."

Colin looked at the material requirements and then silently closed the upper right corner.

This thing is too demanding, so the materials on him add up to a fraction of the amount.

Then, he clicked on the option [Hanging City], which looked much more friendly than the underground fortress.

[Tip: Level 1 Hanging City: Floating Stone 0200, Thorns of Suffering 410, Wood 54300, Fog Point 20200.]

Colin had never even seen the floating stone, so he could only shake his head and give up this choice.

Then I saw the third [chariot].

As soon as he turned on it, seeing those functions, Colin couldn't help but lit up.

[First-level tank: can block gray fog, resist mental attacks below the lord level, drive and move, and can carry artillery...]

[Note: Driving a tank requires fuel consumption.]

"If there is a national chariot, millions of steel torrents, artillery plowing the ground, and pushing the gray fog across the road, what are these distortions?"

Colin thought about it with some excitement.

Then I saw the materials it needed and silently clicked on the upper right corner.

Interrupted.

However, the practicality of the chariot still allowed Colin to record the materials it needed and collect them silently.

Now, there is only one last option left: Level 2 territory.

[Second-level territory information: The territory scope of survivors will be expanded from 4*4 to 10*10, and an additional 5*5 courtyard will be added.]

[Tip: Required materials: stone 492000, thorns of suffering 430, wood 541000, clay 0500, mist point 2050.]

Compared with other upgrade plans, the secondary territory seems much more normal.

Some materials seem to be a lot, but because they are basic materials, there are actually not many. After all, these things outside of gray fog are very common, and you just need to spend some time to get them out and put them into your backpack.

The main missing items in the Gray Mist World are still two items, food and water.

Of course, Colin didn't plan to waste this time.

After all, before people find a stable source of water, water can be regarded as a monopoly resource in Colin's hands.

Colin silently calculated the materials he had missing, then divided several portions of water from his backpack, and each portion of 200 milliliters of water was hung on the trading market.

【Level 3 Water】

[Item Description: There is a slight odor, but there should be no problem with drinking it.]

【Type: Consumables.】

【Quantity: 200ml.】

【Selling price: 200 parts of stone.】

[Business Note: If you have other unique items, you can send me a private message.]

"Two hundred milliliters of water have two hundred parts of stone, one milliliter has one part of stone. This exchange requirement is not too much. After all, my water is made of precious wood from the foot of Crow Mountain..."

Colin muttered in his heart.

At the same time, when I saw this scene on the chat channel, someone immediately started to curse.

"Two hundred pieces of stone are only exchanged for 200 milliliters of water, why don't you grab it?"

"Why are there such a shameless guy?"

"It's so dark."

"Everyone must not buy these guys' water. Join together, and you cannot indulge these black merchants!"

Colin, who had been opening the chat channel, naturally saw this information.

But Colin didn't care about it at all.

He sat on the chair he picked up, leaned leisurely against his back, and laughed "hoo".

"If it weren't for the two thousand pieces of stone that had arrived in just one second, I would have thought that your will was as strong as a strong one and formed an unbreakable alliance to unite to resist me. Well, this also shows that there are indeed many of these things, almost everywhere, but I was busy with tasks yesterday and only caring about high-value things, and I didn't notice these..."

Smiling and shook his head, Colin asked the two slaves who had already gotten up to throw out the 49 pieces of stone piled up in the corner of the bed.

Next, the same method was made, and the requirement of 1,000 pieces of wood and 500 pieces was completed quickly.

In this process, the survivors who shouted to resist him split within themselves.

"You scammers are calling us to boycott profiteers together, forcing them to lower prices, and secretly rob them from behind..."

"No, no, no, I can collect hundreds of pieces of garbage in just an hour when I go out. Isn't anyone really treating it as a treasure?"

"I'm talking about it. Some people exchange water for ordinary materials, but they won't change their brains if they have any problems."

"Haha, I got it, I got it! This water tastes so good~"

"Boss, wait for me. There is a mine near my house. I'll dig it now and leave some for me..."

"So much water must have been found. There is no shortage of water at all. But you don't know how your family educates you? Will your conscience hurt?"

...

Watching these people go from "union" to split, Colin was interesting to watch and sent a group every ten seconds, allowing many people to join this monkey-sports feast.

In order to grab the water, those guys who have objections to him have no time to speak.

Especially some people who are not good at brains and spend money on this matter to buy speakers.

Soon, all the basic materials needed by Colin were collected, and all this cost less than three liters of water.

"Is this a monopoly business..."

Colin sighed in his heart that if he wanted to dig all these things himself, he would probably have to dig them to tomorrow, but it took less than ten minutes to pass the equivalent exchange with other survivors.

Monopoly...it's so evil!

"What remains are the troublesome thorns of suffering and 'fog points'..."

The difficulty of collecting these two things has increased to several levels, and it is obvious that one portion of each milliliter cannot be exchanged in this way.

However, while Collin was thinking about how to change it, there were suddenly some replies in the private message.

"Well, my friend, I have something called 'Thorn of Suffering', which is a good thing that explodes from the monster. Can you exchange some water for you? As long as you are willing to change it, I will tell you what it is for..."

Some? This guy seemed to be lucky. Colin touched his chin. He ignored the words behind him because he knew much more clearly than this guy.

In his opinion, the other party probably had to find out how they could be made of clay or axe.
Chapter completed!
