In the afternoon.
After more than half a day.
Half of the water in the big black bucket had already gone down.
The entrance of the library was filled with all kinds of items.
Zhang He carefully sorted out the items and stacked them up into several piles.
After Zhou Yuan saw it, he immediately asked Zhang He to carry them into the library.
Then, he sat comfortably on the sofa and asked the system about each of them.
"How much is this worth?"
[85 gold coins.]
"Hmm, not bad. What about this?"
[3 gold coins.]
"Oh, trash. How about this?"
This time, the system didn't answer immediately, as if it glitched for a moment.
Then, for the first time, the system's voice seemed to have a tone.
[The system can instantly scan all the items in front of you.]
Zhou Yuan was stunned for a moment before he finally understood what the system meant.
The system was saying that it could calculate the value of all the items at once.
It was asking him to please stop asking one by one.
After being slightly startled, Zhou Yuan said,
"Alright, how much are these things worth?"
[Scanning...]
[Scan complete!]
"There are a total of 673 items. Among them, 634 are worth less than 100 gold coins, and 39 are between 100 and 200 gold coins."
[Total value: 2458 gold coins]
It was within Zhou Yuan's expectations that the price of the fruit would not exceed 200 gold coins.
After all, only a zombie crystal core with energy was worth 200 gold coins.
The items that the refugees had dug out from the ruins were all man-made, so it was normal for them to be below 200.
Fortunately, there were a lot of gold coins, and in the end, he had more than 2000 gold coins.
[Host, please confirm if you want to exchange all of them for gold coins.]
Zhou Yuan did not hesitate and said,
"Exchange all of them!"
[Understood.]
In an instant, the pile of items in front of him disappeared like a dream.
On the system's screen, his gold balance became 2873.
Zhou Yuan was not worried that others would question why so many items had disappeared.
After all, he was already a god-like figure in the eyes of Zhang He and the others.
Looking at the four-digit gold coin balance, Zhou Yuan was filled with motivation.
Although the sky was getting dark, he was ready to start the base construction plan immediately.
However, at this moment, the system took the initiative to say,
[The system has detected that the host's balance has reached four digits for the first time. More functions have been unlocked.]
[Now, you can use more gold coins to evolve items into something greater.]
[For example, 100 gold coins could originally evolve contaminated water into drinking water. Now, 200 gold coins could be spent to evolve contaminated water into a nutrient-rich solution.]
[User may even spend more gold coins to evolve the contaminated water into fluid energy.]
Hearing this, Zhou Yuan asked doubtfully,
"More gold coins? How many gold coins do you need?"
[1000 gold coins can be used to evolve contaminated water into the lowest level of fluid energy.]
1000? Heh.
Zhou Yuan pretended that he did not hear that.
Although this fluid energy sounded very high-end, it seemed that he had no use for it at the moment.
All in all, the system was now saying that the more gold coins he spent, the better the effect of the evolution.
Thinking of this, Zhou Yuan clenched his fists.
He was considering if he should evolve his strength again.
However, after thinking for a while, he gave up.
With his current physical fitness, it could be said that it would be difficult for him to find an opponent.
In addition, he now had Zhang He and so many underlings.
He was safe for the time being.
The most important thing now was to build the base, and not a single gold coin could be spent carelessly.
Zhou Yuan nodded and walked out of the room.
At this moment, Zhang He had already packed up the stall outside the door.
He immediately walked over respectfully when he saw Zhou Yuan.
Zhou Yuan ordered,
"Two things,"
"First, spread the news that I want to buy live fish. The price is negotiable."
"Second, find some people to help me build a wall. They will be rewarded with drinking water."
Zhang He respectfully agreed, then carefully asked,
"Mr. Zhou, the wall... Where should we build it? And...how?"
Zhou Yuan threw a piece of paper to Zhang He and said,
"This is the blueprint. It's marked in detail. Build the one on the lakeside first."
Zhang He carefully unfolded the folded blueprint.
When he understood the contents, his face was filled with surprise.
This was because the map roughly depicted the entire camp.
The two teaching buildings, the library where Zhou Yuan lived, the fields, lakes, and ruins of buildings of various forces.
Then, a solid line was used to mark out the areas in many places.
It was indicated on the side that the solid line represented the wall.
If one looked at the overall situation, these walls would cover more than half of the camp.
At present, it included the library, the fields, the lake, and the ruins of buildings.
If all the walls were built, this area would be separated from the two teaching buildings.
Zhang He could not understand why Zhou Yuan would do this.
However, this did not affect his loyalty in carrying out Zhou Yuan's orders.
After what had happened this morning, he was now completely devoted to Zhou Yuan and would follow him until death.
Therefore, after receiving the blueprint, Zhang He immediately started looking for people.
On one hand, he had people spread the news about wanting to purchase live fish.
On the other hand, he began to look for laborers and people who knew how to build houses.
It was a quiet night.
The next morning.
Zhou Yuan walked out of the room.
Looking at the big bucket of fish in front of him, he was a little stunned.
The bucket was half a meter in diameter and almost a meter in height.
It was filled with fish.
Zhang He, who had been waiting for a long time, said,
"Mr. Zhou, I wasn't sure what kind of fish you like."
"That's why I took two to three of each. "
"Do you think these are okay?"
Zhou Yuan did not know whether to laugh or cry.
The reason why he wanted live fish was not to eat them.
"I'm not planning to eat the fish."
"By the way, why can we still catch so many fish?"
When Zhang He heard Zhou Yuan say that the fish was not meant to be eaten, he looked a little embarrassed. Then, he explained,
"You may not know this, but in the early stages of the disaster, there were still many fishes."
"Including the lake not far away."
"However, later on, the water quality became worse and worse, and the fishes started to die in large numbers."
"In order to continue developing, many people catch the fishes and keep them in their own ponds."
"So, these fishes are not naturally wild."
"They're all raised by the families themselves. "
Zhang He felt a little emotional.
"However, as time passes ..."
"Water resources are becoming more and more scarce. Most people can't afford to raise fish."
"When you're extremely thirsty, you can even finish the water used to raise fish."
"However, with your presence, this campsite will definitely not lack water in the future."
"You are the savior sent by the heavens!"
At the end of his sentence, Zhang He couldn't help but flatter Zhou Yuan.
However, he sounded so stiff that Zhou Yuan felt a little scared.
"Carry the bucket of fish and follow me."
Zhang He and his underlings carried the bucket and followed behind Zhou Yuan.
They arrived at the lakeside.
At this time, there were already hundreds of people working in full swing.
The outline of the wall had already appeared.
Walking down the stairs, Zhou Yuan arrived at the water's edge.
At this distance, the sour and stinky smell of the lake water was extremely pungent.
Zhang He covered his nose and asked in a muffled voice,
"Mr. Zhou, are you going to raise fish in the lake?"
"This... the fish will die in contaminated water."
The fish were kept in indoor ponds or fish tanks.
Although they had escaped the destruction of the apocalypse, the fish had become an existence similar to the flowers in the greenhouse.
It was impossible for them to survive in the polluted water in the wild.
Zhou Yuan ignored Zhang He and said to himself,
"System, 100 gold coins to evolve the fish in this bucket!"
[Received.]
[Evolving.]
[Evolution complete. The ordinary river fish has evolved into "Active Water Purification Fish"!]
