This map was projected by "Dream" in Yan Fei's mind. As long as Yan Fei wishes, he can click on any area to zoom in, allowing him to know all the conditions of the Solar System Core Region. Moreover, this map is constantly changing in real-time, and these changes mirror the actual changes in the solar system exactly...

The quantum satellites breaking out of the Kuiper Belt, except for the one left in the Kuiper Belt, continue to fly at high speed towards the outer solar system. As soon as they safely reach the furthest exploration point of the first quantum satellite, Yan Fei will control one of the quantum satellites to stop and activate its detection equipment to survey the starry sky within a radius of 100 billion kilometers. This will form a surveillance network with the first quantum satellite, helping Yan Fei master all the conditions inside the inner solar system.

Quantum satellites are Yan Fei's eyes to observe the universe, but ultimately, the function of quantum satellites is limited. To truly explore the universe, Yan Fei still needs to dispatch his Cosmic Exploration Fleet. However, before establishing his Cosmic Exploration Fleet, Yan Fei must first create a stable rear base for himself. Unfortunately, Yan Fei's Dreamland Cave World is a reliable base, but for confidentiality reasons, this base, which can rival Earth, cannot be shown to the world, so he can only build a Space Transfer Base that can be shown to people.

To construct a real Space Transfer Base inside the Solar System, it's not just about building the main body of the base, but also constructing a vast number of defensive weapon systems on it. It's imaginable that these weapon defense systems are not targeted at Earthly forces because, under the suppression of Dream Island, other Earth forces can hardly enter the universe, so Yan Fei aims to defend against threats from outside the solar system.

Although Yan Fei is invincible within the solar system, he has had uncomfortable feelings pop up several times on a whim, vaguely sensing that in the near future, a powerful alien civilization might appear. He will have a grand battle with that alien civilization, and only by defeating the invasion of the alien civilization can he ensure the safety of Dream Island and Earth humans.

Based on previous intelligence obtained from Captain China, Yan Fei faintly deduced that the powerful civilization they would soon encounter might likely be the survivors of the Cultivation Civilization that left Earth 80,000 years ago. The person causing them to return to the solar system is likely Duan Hongyu, who has the Yin Yang Battle Order Heavenly Sorrow Talisman within her body.

If it were before, Yan Fei was too weak and had not yet broken out from Earth. But after the Drone Upgrade to level 6, his strength significantly improved. If the survivors of the Cultivation Civilization indeed return to the solar system, he is confident he can have a grand battle with them and even defeat their attacks. Therefore, he plans to construct a Space Transfer Base with strong defensive capabilities as his Battle Fortress outside of Earth.

In Yan Fei's mind, the best location for this Transfer Base is on Mars. He plans to fully militarize Mars and install various defensive weapons on it. Once foreign invasions truly occur, Mars will immediately become a spiky Battle Fortress, protecting the safety of Earth deeper inside.

However, Yan Fei won't place all his hopes entirely on Mars. He intends to make use of a large number of planets within the solar system. He will build numerous high-power energy turrets on them based on their positions and characteristics, making them Mars' outer defense line. By using these energy turrets to attack, he aims to slow down the enemies' progress into the solar system. Then, Yan Fei will deploy his Drone Carrier, focusing all efforts to eliminate these invaders and destroy the enemy outside the Solar System Core Region.

Given Yan Fei's nature, he would undoubtedly choose to stop enemies at the national gate, as only this ensures the safety of his Core Area and guarantees he won't suffer huge losses. Although, in the face of powerful enemies, Yan Fei could retreat back to Dreamland Cave World to secure his absolute safety, Earth is also Yan Fei's homeland, and he does not want his homeland destroyed. Only when it truly reaches an irretrievable point will he withdraw from the solar system.

Currently, due to the energy shortage in Dreamland Cave World, Yan Fei's controllable area is only within the Kuiper Belt of the solar system, and he remains powerless over the more distant Oort Cloud Zone. Thus, he can only undertake massive construction activities within his sphere of influence, and given time, he could fortify the entire solar system, preventing any enemies from entering it.

In constructing Mars as this Transfer Base, to building a systematic planetary defense system throughout the solar system, acquiring all these resources solely from Earth is akin to a drop in a bucket, unable to sustain such a large-scale construction. Luckily, since Yan Fei virtually owns the entire solar system, he can conduct resource extraction on all its planets. He has an abundance of resources at his disposal. Given certain time, he can construct the solar system to be solid, genuinely protecting Earth's safety.

Upon further analysis, Yan Fei concluded that the first step of opening up the universe is truly conducting resource extraction within the solar system. Only by establishing the solar system well can he use it as a springboard to venture into the universe outside it.

To meet the resource demands for upgrading the Drone to level 6, Yan Fei painstakingly arrived at the Spirit Divine Star in the Asteroid Belt for various resource mining efforts. However, at that time, Dream Island Technology was still at a low technological level, and the resource mining equipment was very rudimentary, resulting in extremely slow interstellar resource extraction speed for Yan Fei. Merely retrieving resources for the Drone Upgrade took an incredibly long time without even refining them. If the resource extraction speed remains so slow in the Cosmic Era, then Yan Fei's cosmic exploration prospects are worrying.

Fortunately, after breakthroughs, Dream Island's technology advanced rapidly, with all technology improving several notches compared to before. Yang Qi has designed more advanced interstellar mining equipment, and once these mining devices are deployed, they will significantly increase Dream Island's resource gathering speed. If combined with the incredible space of Dreamland Cave World, Yan Fei's resource acquisition speed will become even faster.

Yan Fei will conduct mineral resource extraction on all planets within the solar system, except Earth. With the technical means currently mastered by Dream Island, if Yan Fei wishes, regardless of whether these resources are located at the seabed or Earth's core, he can extract them all in a very short time, leaving nothing for Earth humans.

However, Yan Fei harbors a strong sense of looming danger. Although he is now invincible within the solar system thanks to the Drone Carrier, he dares not ensure invincibility within the universe. If Dream Island encounters aliens during its cosmic journey and gets annihilated by them, Earth's resources haven't been mined, and Earth humans can still use Earth's resources, giving them a chance to rise again. If Yan Fei exhausts Earth's resources and fails, then Earth humans who haven't entered space will have nothing, with no hope for resurgence.

On the Spirit Divine Star in the Asteroid Belt, 370 million kilometers away from Earth, the older primitive mining equipment at the former mining site has been replaced with the latest high-tech mining equipment, surpassing the previous mining efficiency by over 100 times. This equipment is produced in Dreamland Cave World's Fully Automatic Production Workshop, all designed by Yang Qi. Moreover, the products manufactured can also be used in the outside world, so they are transported through Space Channel to Spirit Divine Star for planetary resource extraction.

When Yan Fei increases the production capacity of the Fully Automated Production Workshop in Dreamland Cave World to its maximum, along with ample raw material reserves, in just one month, the number of advanced mining devices he produced reaches one billion. Once these devices are activated, they are immediately taken over by the Earth-based Artificial Intelligence "Dream," and under "Dream's" control, they mine the necessary resources on Spirit Divine Star.
