Classification refinement, evolution, purchase of metal sheets

"Small island: 303 square meters in area (9 cornerstones remain unused), some resources will be randomly refreshed on the island's empty land every day."

"Empty land is a location that has not undergone special human treatment."

"The larger the island, the more resources will be refreshed, note: the current classification of resources is refined!"

"If a refreshed resource, is not handled in time, it will slowly evolve and refresh new resources that rely on this resource."

Seeing the system's prompt message, Xiao Yi was a bit puzzled and asked, "What does resource classification refinement mean?"

"To give you a chestnut, one of the materials you caught before was a metal sheet, but this material will not appear in the future, it will be refined into specific metals, such as iron, copper, tin and so on."

Xiao Yi pondered for a moment and asked, "That means, when you make things in the future, if it's something that requires iron, using other metals won't work?"

"Yes!"

"What about the metal pieces that were fished out before?"

"Universal!"

Xiao Yi nodded, then immediately rushed to the island monument and shelved fifty sets of cool white water.

"[Tap Water]*30ml trade for [Metal Piece]*1."

The metal sheet that could be generalized in the future was definitely the rarest of supplies, and whichever metal couldn't be collected anymore could be completely replaced with this!

However, Xiao Yi was worried that he had acquired too much and made people with good intentions notice, so he only shelved fifty groups, otherwise he would have wanted to shelve five hundred groups!

Including the amount of water, originally Xiao Yi also wanted to use 50ml, but again, he was worried that someone would notice something.

30ml of tap water for a unit of metal sheet was already a high price compared to before, and any higher would definitely attract more attention.

But 30ml of water is nothing to Xiao Yi.

If someone was willing to sell a metal piece to himself, Xiao Yi would be willing to use 100ml of tap water to exchange a unit of metal piece!

While shelving the cool white water, Xiao Yi continued to ask, "What did you mean by evolution just now?"

"To give you a chestnut, let's say there are ten trees refreshed on the island now, and you didn't cut them down, and then you continue to refresh the trees at the same location next, and slowly it will turn into woods, and then it will evolve further and become a forest, and with a forest only then will you further refresh the animals that are active in it!"

Xiao Yi suddenly realized, "It's true that the larger the area, the more the harvest!"

"But in that case, wouldn't that mean that the island can completely evolve land that can be cultivated?" Xiao Yi was filled with doubt, "Then what is the significance of the Soil Improvement Card that appeared before?"

"Soil Improvement Card, fast, won't sand, natural evolution, extremely slow, bad protection will have the possibility of sand!"

Xiao Yi nodded, finally completely figuring out what kind of changes had happened to the island!

Or to put it in game terms, what exactly was updated in this system update!

"The bigger the island, the bigger the advantage!" Xiao Yi muttered.

"Attention: it is also possible for the islands to refresh various animals that are a threat to humans!"

Xiao Yi was slightly stunned, then immediately understood that with forests, there was a possibility of refreshing fierce tigers and poisonous snakes, this was normal logic!

"It seems that a large island area is also a double-edged sword, in case one's strength is not enough and one makes the island very large, and is eaten by the fierce beasts on one's own island, then it would be embarrassing!" Xiao Yi muttered.

At this time, Xiao Yi received an inquiry from Su Wan.

Apparently none of them had rested and were waiting for the end of this seawater flooding cornerstone incident.

The queries of the three were naturally all about what the bigger the island, the bigger the harvest meant.

Xiao Yi thought for a moment and simply explained, "The bigger the island, the more resources will be refreshed."

"Also, collect more metal pieces when you have the chance, don't sell them and don't use them!" After explaining, Xiao Yi added another sentence.

"Okay, can I use the supplies in my hand to exchange for metal pieces?" This was Su Wan's reply.

"Yes!"

Jiang Yuntian and Nong Bi Hong, on the other hand, were a bit surprised.

Why was it that something that a big shot like Emperor Lin Tian didn't even know about was like a very simple question when it came to Xiao Yi.

Could it be that Xiao Yi was a prophet?

Although they were puzzled, they knew that some things were other people's privacy and it was not good to just ask.

They could only say back, "Okay, we will pay more attention to collecting the metal pieces!"

"Well, even if we exchange it with some other basic supplies!" Xiao Yi emphasized again.

Xiao Yi's four began to acquire metal pieces in the trading hall, but there were too many Survivors, and the four of them couldn't make any waves at all.

Except for Xiao Yi's slightly larger trading volume, which caused a discussion in the public channel.

"Someone is using tap water to collect metal pieces at a slightly higher price than before."

"Shouldn't we be collecting cornerstones, food and water at this time?"

"Right, what's the point of collecting metal flakes, as long as the manufacturing that doesn't particularly concern one's survival can be stopped for a while, hurrying up to get cornerstones is the proper thing to do!"

"Right, although there's still a week to go, God knows if the difficulty of fishing for the supply crates will increase, if the probability of cornerstones being opened will decrease, and then there's the issue of food and water."

"What the upstairs said is right, if I were to order them, the priority in descending order would be cornerstones, water, food, and then the other supplies!"

"If that's the case, then wouldn't it be possible to get more water back while the brother needs metal pieces?"

"If you have metal pieces and there's no particular need for them, then I think it's possible to exchange them!"

After the crowd's discussion, the tap water on Xiao Yi's shelves quickly sold out.

Seeing this scene, Xiao Yi immediately shelved fifty groups again.

"I guess I'll be getting it late tonight." Xiao Yi said with a yawn.

He had to change enough metal pieces before the crowd could react.

"Those who didn't exchange water just now can hurry to the trading hall, Brother has released another fifty groups!"

Someone yelled within the public channel, and the crowd immediately rushed to the trading hall, those who had metal pieces in their hands frantically trading the water that Xiao Yi had hung up.

"Chairman, someone is collecting metal pieces, should we do it?" Emperor Lin Qinglong privately chatted with Emperor Lin Tianxia and said.

Emperor Lin Tianxia frowned and thought, because the trading hall was able to trade anonymously, so he didn't know if this metal piece collector was the same person as the one who collected the cornerstone before.

If it wasn't the same person, that would be fine.

But if it was the same person, then it was time to consider his motives.

The previous acquisition of the cornerstone was an advance, and the frantic acquisition of the cornerstone before the seawater flooded the area meant that he should have realized something in advance, or gotten some other information tip.

Then this time, did the acquisition of the metal sheet also get other information hints?
