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

Meanwhile, in another dark and gloomy room, three men in military uniforms—one middle-aged and two young men—were waiting anxiously.

If Jiang Fan could see all this, he would be very surprised.

Because these three men not only had obvious foreign features, but their rooms were also exactly the same as the room he was currently in.

Let's go back to when Jiang Fan had just submitted the transaction request, when the three of them were still discussing it.

"Commander Bailey, look! That fourth group that came in just now has submitted a trade request to us! And it's three requests!" one of the young white men shouted to the blond middle-aged man.

"Excellent!" The middle-aged man called Commander Bailey, whose full name was Cole Bailey, couldn't help but exclaim, his face beaming with barely suppressed joy. "I was just thinking about how to trade for his beast meat, but he volunteered instead!"

"Should we just click 'agree'?" another young Black man asked.

"Don't rush! Let's analyze his three applications first." Bailey shook his head.

"Their first application was to exchange 307 kg of Level 1 mutated beast meat for 48 kg of our salt."

The second item is to exchange 49kg of clean water for 10 of our Level 1 Plague Crystals.

The third option is to exchange 388kg of coal for a [Green Building Card - Level 1 Residential Building].

Of the three types of supplies the enemy has, animal meat is the best for us, followed by clean water, and coal is the worst.

But among our things, crystal nuclei are the most precious, followed by table salt, and lastly, residential buildings.

Since we don't lack housing at all, it doesn't mean much to us.

"So, you agree to their first request. We're determined to get the beast meat. As for the clean water, we'll exchange it for [Green Building Card - Level 1 Residential Building]. We'll try to preserve our best resources, Plague Crystal Cores."

The two young men clearly followed the middle-aged man's orders without hesitation.

It turns out they were from a military region stationed overseas by the United States, and four days ago they suddenly found themselves in a primeval forest.

Although the environment here is harsh, they are able to live comfortably here thanks to their modern weapons.

But to everyone's surprise, things changed just one day later.

Biological mutations and drastic environmental changes.

The outskirts of their military district were teeming with animals infected with plague, and even the trees in the forest had turned a sickly dark green. Even when used as fuel, they emitted a foul stench that would make anyone who inhaled it sick.

Even the nearby waters were contaminated by the plague, and even after multiple filtrations, they were still undrinkable.

This resulted in them possessing powerful modern weapons capable of slaughtering alien beasts, but they were extremely lacking in fresh food and clean water resources.

Only after reaching level 2 in Commander Bailey's homestead and unlocking the Interconnected Marketplace did he eagerly utilize the building to trade food and clean water.

They actually unlocked the building on the night of the third day, but since it was past 6 p.m., the first transaction didn't take place until the fourth day.

Today marks their second transaction.

Although Bailey's home can currently produce some food and clean water, it is only a drop in the ocean compared to the enormous consumption of the entire military district.

Fortunately, their military region had stockpiled enough food and clean water to last a week; otherwise, the situation would have been much worse.

Therefore, in order to obtain food and clean water, they would try their best to offer the best things to attract others to trade with them.

On the other hand, after receiving the transaction confirmation and transaction request from Bailey and others, Jiang Fan decisively carried out the relevant operations.

Soon, Pele received a notification.

The young Black man, Aaron Winter, saw the message and couldn't help but ask, "Commander Bailey, they agreed to our request to trade clean water using the [Green Building Card - Level 1 Residential Building], but they haven't confirmed the trade for salt and meat. What should we do?"

Bailey frowned: "The fact that he could produce so much beast meat all at once and offered to trade it for our salt must mean that meat is relatively easy to obtain there, but difficult to preserve, so they urgently need a lot of salt to preserve it."

But after we agreed to trade salt for meat, he didn't click to confirm.

That's probably because we didn't agree to trade crystal cores for purified water, and they felt uncomfortable about it.

Never mind, just bring over the purified water first.

"Okay!" Winter nodded and began to operate the large screen in front of him with his mind.

Soon, the ten icons on the screen decreased to eight.

However, two new forces entered this 27th market during this period, but they have not yet provided any supplies.

Another young white man named Aidan Parker had already returned home and retrieved a large bucket while he was operating in Winter.

The purified water that was traded was initially suspended in the air, until Winter manipulated it with his mind and slowly descended into the bucket.

The entire process was very smooth, without any waste. Even though all three of them had similar experiences, they couldn't help but feel amazed by what they saw.

After this transaction, Bailey and his group still had 10 level 1 plague crystals and 48 kg of salt.

After Jiang Fan successfully obtained the [Green Building Card - Level 1 Residential Building], he also had Level 1 mutated beast meat (307kg) and coal (388kg).

Just then, Jiang Fan used his last chance and sent another trade request to Bailey and the other two: [Coal (388kg) Request to trade Level 1 Plague Cores *10]

"It seems he's determined to get those ten plague crystal cores. He won't let go of the beast meat unless we agree to the deal," the white man, Parker, frowned.

The Black man, Winter, nodded: "But while this coal mine is useful to us, it's far less cost-effective than exchanging it for food and water. After all, we stockpiled a lot of wood that can be used as fuel on the first day, and these 10 crystal cores are not a small amount for us either."

Bailey listened to their analysis and slowly said, "But it is an undeniable fact that we urgently need food. Although salt is also important, it is not irreplaceable."

Whether someone else obtained a salt well like us, or someone hoarded salt before traveling through time, it's possible that they would offer some salt for trade.

If other forces were to trade away this beast's meat, we would suffer a great loss.

"Agree to their request and exchange the crystal cores for coal." Finally, Bailey gritted his teeth and issued the order: "Although this is a bit of a loss, as long as we get the beast meat, our goal will be achieved! Besides, we still have more than 30 level 1 plague crystal cores in reserve, so losing these 10 is nothing."

Winter quickly took action.

Shortly after, the icons for coal (388kg) and level 1 plague crystal cores (10) disappeared from the big screen at the same time.

At the same time, three new icons appeared on the big screen, clearly showing that the two forces behind them had figured out the rules and were preparing supplies for the trade.

But Jiang Fan didn't have time to wait any longer and directly confirmed the transaction message on the big screen.

At the same time, two more icons disappeared from the big screen.

However, the missing icons were not mutated meat and salt, but mutated meat and iron ore.

The expectant expressions on the faces of Pele and the other two instantly froze.
