This spherical detector, besides being used for meteorite detection, can also be employed for various types of mineral exploration and monitoring.

The detector not only prevents detection by current global radar systems but also possesses light refraction stealth capabilities. Coupled with its built-in anti-gravity propulsion system, it makes no noise during flight.

Therefore, even if it hovers more than ten meters above a crowd, it won’t be detected by people. Only when one is a few meters away can the human eye see some light refraction disturbances caused by it in the air.

The only drawback is that it needs to replace its nuclear fuel every 10 days. Yes, it uses nuclear power, which is a technological breakthrough in fusion energy that Wu Hao achieved after developing fusion power generation equipment.

Wu Hao has now managed to miniaturize fusion energy for use, and this fusion method is not the previous hot fusion but a more advanced cold fusion.

Only cold fusion can reduce fusion energy to a very small device.

This explorer detector is an advanced multifunctional device equipped with cold fusion as its power source and anti-gravity propulsion for drive.

However, despite using cold fusion as its energy source, the detector’s size is still too small, with a diameter of only 50 centimeters. It not only has detection and anti-gravity devices but also an energy source.

The energy required for the anti-gravity propulsion system is substantial, so even though fusion energy is very powerful, it can only sustain the detector for 10 days. After 10 days, a new fusion module must be installed.

Currently, although the detector has been successfully developed, Wu Hao only produced 10 units to first use them in the Qinling region for search purposes, also serving as a test for the detectors to allow for future improvements.

One day later, 10 silver-white spherical Explorer II-type detectors flew out from a passage on the outskirts of the Qinling base, beginning to disperse across the Qinling Mountains for exploration.

Wu Hao’s Qinling base has long expanded beyond the original mountain area and into a large underground space because there is a mineral vein below the mountain. As minerals are mined, the underground space continues to expand.

Simultaneously, the base now has multiple passages leading to the outside world, the farthest of which is over 10 kilometers away, making the base fully accessible from all directions.

And this is only the current state of the Qinling base. According to Wu Hao’s plans, he will also develop a longer passage from the base, with its exit reaching a lake several dozen kilometers away. The purpose of this passage is to prepare for the future entry and exit of his spacecraft.

The entry point below also serves as a transfer station to the base because, apart from this location, there is no more suitable place to build a large passage with relative secrecy.

After all, Wu Hao is planning to build a spacecraft that is not the small type from before but a 50-meter diameter disc-shaped spacecraft, based on the widely circulated UFO shape found online.

Moreover, there is a crucial reason: the circular spacecraft is more suitable for anti-gravity propulsion systems. Its effectiveness in radar detection prevention and stealth capabilities is also better.

However, with the resources currently available at Wu Hao’s base, building such a large spacecraft is impossible. Therefore, Wu Hao must purchase and transport many raw materials from outside the base during this period.

He must also personally participate in the base expansion and passage construction work because only with his involvement can these constructions be completed on schedule. Otherwise, the base’s current construction capacity and resources would not be sufficient to complete such a large-scale project within the expected time frame.

Time flies, and without realizing it, Wu Hao had been at the Qinling base for more than three months. Through these three months of construction, the final expansion of the Qinling base was completed half a month ago. Only the last twenty or so kilometers of the passage remain unfinished. After all, this involves excavating a tunnel more than sixty meters wide and thirty meters high hundreds of meters underground.

Excavating such a large space at a depth of several hundred meters is no easy task. If not for Wu Hao’s recent evolution, which allows him to exert a telekinetic force of hundreds of tons, such progress would have been impossible in just a few months.

He has now not only completed all base expansion work but also excavated nearly thirty kilometers of the final passage.

It is worth noting that Wu Hao developed several types of large-scale excavation and transportation machinery for the base expansion work.

One of these machines is particularly special because it takes soil, rocks, and sand from underground, sucks them into a sealed space, and uses two powerful magnetic fields to create high pressure. After adding several special chemical agents, the scattered waste materials are turned into building materials through high pressure and chemical agents.

Turning soil and rock waste into building materials harder than ordinary stones is not complex. It is not a fantastical idea because in nature, all stones form from the long-term accumulation of soil and sand.

Therefore, the principle of this large high-pressure machine Wu Hao developed is to use an electromagnetic field to create a high-pressure environment, transforming loose soil, rocks, and other waste into various shapes of building stones using high-strength agents in this high-pressure environment.

The strength, hardness, and corrosion resistance of these stones far exceed the highest-grade concrete available on the market. Thus, the materials made from the underground waste not only meet the consumption needs for base expansion but also eliminate the need to transport waste outside.

Because these waste materials have been compressed into blocks of material used to reinforce the underground space, and due to the high pressure, the original large amount of waste is compressed into relatively small building stones. Thus, there is no need to worry about any waste needing to be transported out during the base expansion.
