After Yan Fei completed the drone upgrade, he would continue to extract resources on Spirit Divine Star, aiming to transport all of the planet's resources to the Dreamland Cave World. If it weren't for the size limitations of the Dreamland Cave World's space channel, which couldn't open a channel large enough to accommodate the Spirit Divine Star, he would already be looking for ways to move Spirit Divine Star into the Dreamland Cave World.
Among the raw materials needed for the drone upgrade, most could be obtained locally on Spirit Divine Star. However, there was one thing that Spirit Divine Star lacked, and that was one hundred billion tons of oil. Yan Fei had already decided to upgrade the Drone Avatar on Spirit Divine Star. His biggest problems now turned into two: the first being the choice of location for the drone upgrade, and the second being how to transport the oil resources from Dreamland to Spirit Divine Star.
