Among all the supplies, the most conspicuous was the fuel used to power the Mechanical Desert Spiders.

"Here are 30 one-ton methane tanks, we haven't finished counting the 100-kilogram ones yet, but there are at least 2,000 of them, plus over 400 twenty-kilogram ones, for a total of at least 200 tons!"

Black Smoke led Lu Yuan to a corner of the cave, pointing at the mountain of fuel tanks.

Seeing this precious methane, even Lu Yuan couldn't help but smile.

Now, the spaceplane's extra-atmospheric fuel finally had a source!

"I found weapon modification parts that haven't been installed yet," Caoyuan also reported, "heavy machine guns, heavy grenade launchers, flamethrowers, they're all here, and the ammunition too. The quality is quite good, but the design completely disregarded ergonomics because they weren't designed for humans at all. The weight is far too much for infantry."

"It doesn't matter, getting them is a gain."

Lu Yuan squinted and smiled. At this moment, he had already thought of the uses for these weapons.

"Team Leader! We found a reserve of high-quality titanium alloy in the hive, nearly ten tons!" Guo Li Cheng ran over from a distance, "And it's really strange, some of it looks like it melted and then solidified."

"Hmm, that looks quite old then," Lu Yuan replied casually.

On this planet, it's not strange for metal to have melted, indicating it went through that world-burning doomsday event.

Titanium alloy is the main material of the Mechanical Desert Spiders, equivalent to their "flesh and blood". It's natural for the hive to store more, which also explains why they stole the spaceplane's engine wreckage before.

Auto-loot was forgotten to be turned off.

So far, the gains were quite substantial, but what Lu Yuan was most concerned about were the production facilities that occupied most of the Mechanical Hive's area.

After a detailed inspection, Nan Guo de Xue came to Lu Yuan to report, her tone calm.

"We obtained the blueprint for a device that converts organic nutrients into methane. In the future, ground vine taro can also become our energy source."

"However, considering the need to maintain the underground ecological balance, the amount harvested each time should not be excessive."

"Then, there's the main body of the hive." Nan Guo de Xue turned and looked at the complex production line, "Overall, this production line is quite advanced, but it's not fully automated. The small Mechanical Desert Spiders we saw earlier are the production line workers."

"With sufficient raw materials, the production line can assemble one combat-type Mechanical Desert Spider every half day."

"One every half day? Over 700 a year?"

This speed greatly exceeded Lu Yuan's expectations. It was a good thing the team's progress was fast enough, otherwise, if they had dragged it out too long, they might have been pushed back.

"That's very efficient... Can it be used to produce other things, like our military exoskeletons?"

Nan Guo de Xue shook her head.

"Not yet. The technical level of exoskeletons is actually higher than that of Mechanical Desert Spiders. The production line needs to be upgraded first."

"Okay, I understand. We'll discuss that later."

"Executive Officer!" At this moment, Jubian's voice came over, "I found some important documents that you might be interested in reviewing!"

Lu Yuan followed him to the main control panel for the entire production line.

"When the Queen Spider surrendered, she also removed all the system passwords," Jubian explained, pointing at the display screen eroded by time, "We found the documents left by the previous administrators."

Over the next hour or so, by reading these valuable documents, Lu Yuan gained a preliminary understanding of Li Star's development history.

The earliest developer of this planet was his own family, Cangyuan Future Technology.

In the 23rd century AD, while the passengers on the "Cangyuan 1" were still hibernating on their long journey, human society experienced a technological explosion, quickly mastered faster-than-light travel technology, and gradually ushered in the "golden age".

Cangyuan took a liking to Li Star, which once had life but was in a state of ecological collapse and deathly silence when discovered. They carried out Earth-like recovery and transformation on the planet.

Half a century later, the Earth-like transformation was basically complete, and Li Star was transformed into a habitable planet.

The Mechanical Desert Spiders, officially named "Mech Guardians", were originally intelligent robots used to build underground infrastructure, evolved from 21st-century robot dogs. Like the Desert Spiders, they were artificial species meticulously designed and introduced by Cangyuan according to the local environment, which is why they have similar appearances.

But Cangyuan didn't have time to further develop and build this planet. In an interstellar war, Li Star was occupied by Infinite Deep Space, a cosmic giant enterprise of similar strength.

However, Infinite Deep Space's occupation only lasted for one year. A year later, a third force launched an invasion.

This force was the United Earth Government UEG, the oldest in history.

After the UEG launched the invasion, the Mechanical Desert Spiders were captured by Infinite Deep Space, then reprogrammed to resist ground attacks, serving as cannon fodder.

Mechanical Desert Spiders cannot distinguish complex human lies and disguises; their logic for distinguishing friend from foe is very simple and crude. At that time, humans under the Infinite Deep Space faction had begun large-scale genetic modification, and their genes were no longer pure, while the citizens of the UEG still maintained a high degree of genetic purity.

As long as the target human's genetic purity was above 90%, the Mechanical Desert Spiders would fire directly.

Therefore, whether it was Lu Yuan later or other Cangyuan Future Technology employees, although they were not affiliated with the UEG, they would still be attacked because their human genetic purity was close to 100%.

In the end, there were no winners in the battle for Li Star.

Infinite Deep Space and the UEG fought fiercely here for two years, consuming a large number of troops, and finally had to sign a ceasefire agreement, denationalizing Li Star and setting it up as a buffer zone.

The log ends here.

Lu Yuan speculated that after that, probably only a few destitute refugees came to settle on Li Star, causing the planet to be gradually forgotten by mainstream civilization.

Now, everything has become a fleeting memory. The truly significant discovery in the documents were several maps from the Cangyuan developers.

Those were remote sensing images of the planet's natural resources, clearly showing the large mine in Red Iron Town and the large oil field in the central Desert basin.

Outside the Desert, there were many more abundant resource points, densely packed. These resources are now covered under tens of meters of glassy substance, long forgotten by the native inhabitants of the Desert.

After inventorying all the spoils, the players spontaneously organized a celebration.

The recorded video of conquering the instance quickly spread on the internet. Wo Yao Chi Dan Ta, who died midway, unexpectedly became popular, with people constantly @-ing her, asking what it felt like to have half her body burned off by a laser cannon.

Play is play, but the development of the camp must continue.

Lu Yuan planned to get the spaceplane into space as soon as possible.

This was an important task for the near future.
