The entire school embarks on a survival journey, starting from a primeval rainforest.

Salt is indeed a good thing, but Jiang Fan has his own salt well, so why would he choose to exchange the meat of a strange beast for salt?

Moreover, even without salt wells, he had ice cellars to preserve food.

As for daily consumption, the resource card and the stockpiles from several supermarkets in the East Campus are more than enough for the short term. Jiang Fan's needs are not as urgent as Bailey and the others imagined.

His first trade request was to trade meat for salt in order to lull Bailey and the others into a false sense of security, making them believe that he really needed salt to preserve the meat.

But from beginning to end, he only wanted four kinds of supplies.

Residential building, iron ore, 10 plague crystal cores and 5 frost crystal cores.

Although residential buildings are extremely important to him, he doesn't see them as universally applicable.

After all, not everyone's residence has a large group of women willing to depend on others, and not everyone's dormitory is flooded by the lake, causing the people there to feel extremely insecure.

These were originally disadvantages for Jiang Fan's environment, but now they have transformed into advantages for the development of his home.

So from the very beginning, Jiang Fan had planned to exchange clean water or coal for residential buildings.

As for the other extremely important iron ore resource, he had always thought of exchanging it for mutated beast meat.

After all, food is always the hard currency in a post-apocalyptic environment.

Even he, since his transmigration, has never felt that his food reserves were sufficient.

Even if they have enough to eat, their companions and other permanent residents also need to eat. They have enough to eat and can exchange food with people in the East Campus for supplies at any time.

Therefore, of the four trade requests Jiang Fan initially sent, in addition to the three sent to Bailey and his two companions, the other one was to trade animal meat for iron ore.

At the same time, he received the other party's consent immediately.

He simply hadn't clicked "agree" on the message that one party would trade meat for salt and the other for iron ore.

As for the last transaction request, Jiang Fan intended it as a fallback plan.

In his original plan, if the first force that was most likely in the ice field or glacier environment did not take the initiative to make a trade request to him when he saw that they urgently needed coal resources, Jiang Fan would take the initiative to make a trade request to the other party in order to trade for the 5 frost crystal cores if he could not trade for the plague crystal cores.

After all, we also have to consider the possibility that the other party, as the first force to enter the market, has already used up all their transaction request attempts.

However, the actual situation was better than Jiang Fan had expected. The other party immediately sent two transaction requests: one for trading frozen fish and the other for trading crystal cores for coal.

Therefore, after Bailey and others traded clean water with him using residential buildings, Jiang Fan tried to trade plague crystals using coal mines.

He was already prepared that if the other party did not agree within 5 minutes, he would quickly exchange coal for frost crystal cores and beast meat for iron ore before leaving.

Unexpectedly, the final result perfectly achieved his plan.

The residential building, 10 plague crystal cores and iron ore—in the end, they got them all.

Unlike Jiang Fan, who was smug and self-satisfied, Bailey and his two companions couldn't help but start cursing.

"Fuck!"

"Damn it, they lied to us!"

"They never intended to exchange animal meat for our salt; they were deliberately misleading us!"

"You shameful bastards, I really want to kiss their asses hard with my hard boots!"

They were prejudiced from the start, assuming that while the three of them were working together to develop the transaction plan, Jiang Fan's side was also composed of three treacherous individuals secretly plotting to scheme against others.

The three of them never expected that instead of getting the beast meat they were so sure of, they would be traded for their most precious crystal cores with what they considered the worst resources.

If I had known, I shouldn't have been greedy for the crystal cores. I should have applied to trade the crystal cores for animal meat immediately!

But it's too late to say anything now; all that's left for the three of them is anger and regret.

Meanwhile, Jiang Fan had deliberately left a piece of wood behind the market room and began using the wooden baskets he had used to bring in the coal to move the iron ore back to his home.

It took five baskets to move all 348 kg of iron ore out of the market room.

The commotion he caused had already attracted the attention of a group of people. Putting aside the fact that the market building itself exuded an air of mystery, the fact that Jiang Fan had just had three items of supplies moved in and then immediately brought out iron ore was something that many people found novel.

Among this group was Li Wanneng, who was directing others to forge iron not far away.

On the first day, in order to save time, the axes and pickaxes they made were actually "crude and poorly made". Many of them became too dull or the hammers fell off after only one day of use, and they had to be reworked.

When Li Wan saw that Jiang Fan had brought out a bunch of iron ore from the market, he couldn't help but come over.

"Great! Finally, we have new iron ore!" Li Wanneng exclaimed, then frowned slightly. "But this iron ore seems a little different from the first batch you gave us!"

Jiang Fan nodded, he also sensed the difference: "The first batch was iron ore given by two green resource cards. Those were more uniform, each piece of iron ore was about the same size, like a product of an assembly line, but these are more like they were mined by hand."

Li Wanneng picked up a few stones and examined them carefully, saying, "Judging from the color, this batch of iron ore should have a lower iron content than the previous ones."

Although the first batch of iron ore was called iron ore, it contained almost no impurities, and it wouldn't be a problem to simply call it iron.

I estimate that this batch contains about 1% to 2% impurities. Although there are many more impurities, it is still definitely high-quality iron ore.

It's just a bit troublesome to deal with.

Jiang Fan wasn't very interested in his theoretical analysis; he had other things to do, but he still had to put on a show.

He nodded in deep agreement and praised, "Wan Neng truly lives up to his name; he knows a lot. I'll leave these things to you. I heard from Ding Rui that you complained to her several times that there wasn't enough iron ore. This will at least temporarily solve your immediate problem."

After he finished speaking, he ignored Li Wanneng, who was a little embarrassed by the praise.

Leave your home through the teleportation portal, find Ding Rui, and give her the [Green Building Card - Level 1 Residential Building] to process.

Because this thing occupies 15m*15m, just like a level 1 apartment building, it is a very high-quality green building. However, Jiang Fan didn't find a place to put it right away because there wasn't enough open space in his home right now.

Then Jiang Fan returned to his room in the market and carefully took out the ten plague crystal cores.

He couldn't help but feel a surge of excitement.

He originally intended to use this thing to try and find a suitable pet to absorb within the Starfire, but he simply gave it to Li Wanneng so that he could try to use it to make arrows with special functions.

But I never expected that the moment I got my hands on this thing...

The Heavenly Cloud Vine once again sent waves of longing through him.

He couldn't help but wonder, could it be that the Heavenly Cloud Vine isn't only capable of absorbing crystal cores with the single attribute of lightning?
