Yan Fei could not guarantee that his Dreamland Cave World would remain undetected by other civilizations, so he needed to reserve more energy to ensure its safety. Without the Dreamland Cave World, Yan Fei would lose his most robust logistical development base. Even if he still had the Drone Avatar, he could only protect a very few close relatives and would be unable to lead large numbers of Earth humans off Earth, nor could he rely on Earth humans to grow and strengthen. If faced with an unbeatable enemy, he would have no escape and only a dead end.
But if he could quickly replenish energy for the Dreamland Cave World, then with the support of sufficient energy, all difficulties would be easily resolved. Yan Fei promptly asked, "What should I do to replenish energy for the Dreamland Cave World?"
