Super Invincible Battleship
Chapter 830

Chapter 830: Chapter 342 Prehistoric Civilization_2 Chapter 830: Chapter 342 Prehistoric Civilization_2 In this cavern, unlike the ones above, there was sunlight filtering through fissures overhead. Bathed in this light, Yan Fei discovered that the underground cavern was filled with vegetation and vines. Amidst these plants and vines lay a large metal object, seemingly plunged upside down.

The Mechanical Sparrow was too close to this metallic object to discern what it truly was. So, Yan Fei maneuvered the Mechanical Sparrow to fly upward in order to get a clearer view. Once the Mechanical Sparrow ascended to a certain height, Yan Fei, through the VR device, finally saw what the metal object was.

However, Yan Fei had never expected to encounter such a thing here and could hardly believe his eyes. He first removed the VR device, rubbing his eyes vigorously before putting it back on his head to continue examining the object. Ultimately, Yan Fei confirmed that the object inverted among the plants and vines was not some peculiar entity but a mysterious aircraft.

This aircraft was inverted underground, appearing to have plunged straight from the sky into the earth below. The craft's design was distinctly science fiction in nature, its body made of a mysterious silver-white metal. The silver-white glow the Mechanical Sparrow had initially detected was sunlight reflected off a piece of the aircraft's material. Unfortunately, only the front half of the aircraft was present, and it was in shambles, clearly beyond repair.

Yan Fei was thrilled, hastily controlling the Mechanical Sparrow to photograph the mysterious aircraft. At first glance, this crashed craft was a high-tech product. Its inherent technology was clearly far more advanced than the current technological level of Earth just from its design. However, judging by the impact traces the craft made on the cavern and the moss-covered body with the nose buried in vegetation and vines, it was evident that the aircraft had been in this cavern for over ten thousand years.

Back then, humans had not yet stepped onto the historical stage, nor had human civilizations emerged. So, who could have owned this aircraft? How did it end up here? After encountering something so blatantly contrary to common sense in the cavern, Yan Fei was momentarily stunned. If such advanced technology had existed in human history, was it possible that human history was about to be rewritten? Or could it be that this was not a human warship at all but an alien one?

Yan Fei felt he was on the verge of uncovering a new discovery about human historical development. He suppressed his excitement and controlled the Mechanical Sparrow to take exterior shots of the aircraft. After he finished photographing, he let the Mechanical Sparrow randomly find a crevice and enter the inside of the aircraft.

Although the exterior cavern had faint sunlight, the inside of the aircraft was pitch black. Fortunately, the Mechanical Sparrow was equipped with a miniature searchlight on its head, which, though it could only illuminate a small area, did not hinder the Sparrow from observing the interior of the aircraft using this light source.

Once the Mechanical Sparrow entered the aircraft, it found the interior teeming with the roots of plants and a layer of humus formed from the decay of those roots. In addition to the plants, there were also some small animals living inside. These creatures, startled by the glowing Mechanical Sparrow, started to flee the area.

Yan Fei could see that the inside of the aircraft was littered with various sophisticated equipment and instruments with unknown functions, but these had been completely worn out by the erosion of air, water, and vegetation. Their former state as high-tech products was unrecognizable; they were covered in moss and weeds, looking more like ordinary rocks.

Although only half of the aircraft remained, its size was still immense. The Mechanical Sparrow flying within it felt rather spacious. Despite the invasion of plants and animals, it was possible to see some very obvious devices intended to control the flight of the aircraft and some of the structural components of the aircraft itself.

As the Mechanical Sparrow flew, it recorded and photographed the scenes. Then it flew into a huge room, which was likely the control center of the aircraft, as it was surrounded by massive screens of unknown purpose. However, the locations of these screens had become hollowed out, indicating that the screens were destroyed upon impact.

Below the screens were some objects resembling electronic devices, but they were beyond repair due to the ravages of time and covered in moss, clearly unusable. Behind the electronic devices were rows of objects akin to chairs.

On one of these chairs, there was something resembling a spacesuit, strapped to the chair with safety belts. The Mechanical Sparrow flew closer to inspect, but it was impossible to see inside the spacesuit from the outside.

The Mechanical Sparrow began searching the control center and then started filming the scenes within. It was at this moment that an all too familiar drone notification popped up, “Special item detected, upgrade essential items necessary for drone upgrade.”

Yan Fei was taken aback. Ever since his drone had been upgraded to level 5, he had constantly been on the lookout for the special items necessary to continue the drone's upgrade. However, since the tip-off about upgrade essential items in the Western Desert of The United States of America during the rescue of Yang Qi, there hadn't been any news of such items.

Unfortunately, when the upgrade essential items were discovered in the Western Desert of The United States of America, Yan Fei had a more pressing mission to complete, which was to extract Yang Qi from the country. Moreover, considering the base in The United States of America was highly dangerous, Yan Fei did not take immediate action to retrieve the upgrade essential items and decided to wait for an opportunity to fetch them.

Therefore, the drone had never acquired an upgrade essential item since its upgrade to level 5. Yan Fei began to wonder if due to the upgraded level, ordinary items were no longer capable of upgrading the drone. Unexpectedly, in the far reaches of Africa, he would once again come across traces of upgrade essential items.

In the Auxiliary Brain, an item shaped like a rectangular prism appeared–this was the real appearance of the upgrade essential items as displayed by the Auxiliary Brain. At first glance, this item seemed somewhat like a brick, also covered with rust, yet it was unclear what it actually was.

Then Yan Fei controlled the Mechanical Sparrow to adjust the surveillance camera, only to discover that the brick-like item was inserted into the console. The part exposed was already overgrown with moss, and if it were not for the reminder from the Auxiliary Brain, Yan Fei would have had no idea where to find it.

Yan Fei was overjoyed. By obtaining this brick-shaped item, he could acquire one upgrade essential item. Furthermore, this find was unclaimed, meaning there was no need to compete with anyone–it was the easiest acquisition of all his items to date.

As long as Yan Fei could continue obtaining the upgrade essential items for the drone, in addition to enough merit points, the drone could be upgraded again. A level 5 drone was already immensely powerful, crushing the fighter jets of all nations in the world. If the drone reached level 6, given the increase in strength with each upgrade, a level 6 drone would truly be invincible on Earth, and no force could stand as Yan Fei's adversary.

Thrilled, Yan Fei continued to control the Mechanical Sparrow to conduct a thorough inspection of the other areas of the flying vehicle, but no further prompts were received from the Auxiliary Brain, indicating that there was only one upgrade essential item within the flying vehicle.

After the excitement, Yan Fei did not linger at the mysterious aircraft for too long. Although it may have been a high-tech warship left behind by a prehistoric civilization, it was not his most urgent task at hand. His priority was to rescue the hostages on Dream Island and ruin the enemies' conspiracy against Dream Island.

As for this mysterious aircraft, it had been situated here for many years without being discovered, which suggested the site was incredibly safe. Yan Fei would explore this mysterious aircraft only after he had rescued the hostages from Dream Island. Moreover, the entrance to this place had been blown up and collapsed. The only way for Yan Fei to enter now was through another passage found by the armed militants.
