The screen was filled with heaps of garbage.
Global 3 type drones were flying rapidly in the sky. The footage captured by two Global 3 type drones showed nothing but garbage mountains, one after another. Some were so vast they formed entire mountain ranges.
The Global 3 type drone flying towards the southeast, however, captured a vast expanse of golden sand, stretching as far as the eye could see.
When the signal transmission was interrupted after twenty minutes, everyone fell silent. They had watched twenty minutes of footage, and the preceding forty minutes had shown only garbage mountains and deserts.
Xiao Yan asked, "Number 1, how far did the three Global 3 type drones fly?"
Chu Shi replied, "All three Global 3 type drones were using low-speed flight mode. They covered one hundred kilometers in twenty minutes."
Ye Fan exclaimed in surprise, "That means at least a two-hundred-kilometer radius is covered by these garbage mountains and deserts. That's enormous. Even some provinces in Dragon Country are not that large."
Chu Shi said, "We'll know the rest of the scenery once the three Global 3 type drones complete their patrol and return."
Ye Fan added, "However, separating the three Global 3 type drones like this carries some risks."
Su Han and the others understood the risk. If the drones were separated and one was shot down, they wouldn't be able to receive the subsequent transmissions.
Chu Shi stated, "There is a risk, but the probability of all three Global 3 type drones being shot down is low. As long as one or two Global 3 type drones return, we can still gather a lot of information."
Su Han remarked, "I never expected you to use such a risky method, Chu Shi!"
Chu Shi calmly replied, "Strictly speaking, the risk of this method is controllable. Dragon Country can replenish even if we lose three Global 3 type drones."
Xiao Yan asked, "So what do we do now? Just wait here for a while and then go back?"
Chu Shi said, "We can go back, or we can stay here and continue our research. Number 0, do you want to go back or stay for a while?"
Su Han asked, "Let's stay here for a while. After all, if we go back like this, we won't gain much more information. Chu Shi, did the signal search device find anything?"
Chu Shi shook his head. "It detected many signals, but these signals don't conform to the rules of Blue Star. We can't decode them."
This was a world different from Blue Star. The signal transmission methods used here would naturally follow a different set of rules, so it was normal that they couldn't be decoded.
Su Han looked at the surrounding garbage mountains and recalled a survival show he had watched. He asked, "Chu Shi, do we still have space left in our portable luggage?"
Chu Shi shook his head. "I've used 3.9999 cubic meters. The remaining space can only carry some sand."
Su Han shook his head. "That won't do. If we carry sand, we'll return naked. That remaining 100 cubic centimeters of volume should be reserved for our underwear."
Before this world could be fully explored, they needed to use their portable luggage space for travel, which included the clothes they wore. While they could pass through the portal wearing anything, the portal would clear any items exceeding the portable luggage capacity. This meant that if they rushed through, their protective suits would be removed, leaving only their undergarments.
Chu Shi's face actually showed a hint of confusion.
Lin Dong asked incredulously, "Number 1, do you really intend to take some sand back from here? What's the use of taking sand back?"
Chu Shi replied, "Taking a sample of sand for research could yield many discoveries. Even returning naked would be worthwhile for scientific research."
He actually had such an idea.
Su Han said, "If we're going to take anything, it shouldn't be sand. One person's trash is another person's treasure. If we're taking anything, let's find something useful for our Dragon Country from the garbage mountains nearby."
Lin Dong commented, "One person's trash is another person's treasure. That saying is truly insightful. I didn't expect Number 0 to say something so wise."
"I saw that in a survival documentary. I don't know who first said it," Su Han said, not wanting to take credit.
Su Han's words immediately made it clear to the others, and they began to examine the surrounding garbage mountains. Among the discarded technological artifacts, there were many mechanical products. If these could be brought back to Dragon Country for research, perhaps new technologies could be discovered.
However, another problem arose: they couldn't bring them back.
Regarding this, Su Han stated, "Everyone, look for good items in the surrounding garbage piles. Find them first, and tomorrow we'll use some portable luggage space to bring them back. When you search, use a radiation detector first to guard against high levels of radiation."
Thus, they began to search through the garbage mountains.
Su Han also started searching.
Adjacent garbage mountains were covered with vast amounts of waste, and among this waste were metallic technological products.
Su Han and the others primarily focused their search on these technological artifacts.
Su Han pulled out several metal components.
The others also found many items.
The things they found were all mechanical creations.
"Look, this thing has several seats on it. Could this be a car? It has no wheels; perhaps it uses levitation technology?"
"This also looks somewhat like a motorcycle. It also has no wheels."
"Then let's take both of these back."
Lin Dong, Ye Fan, and Xiao Yan discussed as they searched.
Su Han quickly stopped their resolve to take the entire items back and said, "You don't need to take the whole thing back. Just disassemble the important parts. See if there's an engine inside. Oh, right, look for anything that resembles a vehicle that can still be started. Engines taken from those would be more useful. Let's use the small drones to search the surrounding area. If it's not here, maybe it's further away."
...
Finding a functional mechanical creation in the garbage mountains was quite difficult, as broken items were discarded here.
However, with the assistance of the drones, Su Han and the others found many items. Whether these found items were treasures or junk would only be known after they were taken back and studied.
