Yang Qi drew blood from Yan Fei's arm, leaving a small wound, which quickly disappeared due to Yan Fei's powerful body's regenerative capabilities. If it weren't for the blood still in the syringe held by Yang Qi, no one would believe Yan Fei had just bled.

Yan Fei lowered his sleeve and said: "Yang Qi, you called me back from outside the Solar System in such a hurry, not just to tell me that you can make Earth humans practice cultivation, right? Although letting people practice cultivation sounds exciting, it won't help improve Dream Island's strength in the short term."

Yang Qi said: "Letting Earth humans practice cultivation is not something important; at most it is a byproduct of my recent Technology Analysis of cultivation civilization. My main achievement is that I finally understand the essence and ultimate secret of cultivation civilization. Relying on this essence and ultimate secret, I not only deduced a lot of methods for cultivators to train, but I also know everything about cultivation civilization, including how they refine tools, how they make talismans, and how they set up arrays."

"That mysterious array on the Space Crystal Wall in your Dreamland Cave World is actually a giant talisman that can quickly absorb dark energy in the Universe and convert it into a special kind of talisman similar to the True Origin Power inside cultivators. The reason you have God's Power in the Dreamland Cave World is entirely because you can mobilize those Mutant True Origin Force and unleash their power. Obtaining such Mutant True Origin Force is very difficult; even a powerful cultivation civilization must pay a huge price to engrave one on the Space Crystal Wall of Dreamland Cave World, and use it to provide sufficient energy for the Dreamland Cave World, preventing it from collapsing."

"The talisman on the Space Crystal Wall can only absorb dark energy from outside the Dreamland Cave World and convert it into True Origin Power. It cannot absorb dark energy inside the Dreamland Cave World. This is mainly because the dark energy inside the Dreamland Cave World is limited; once consumed, replenishment from the outside Universe will be very slow. If the talisman absorbs all the dark energy inside the cave, the Dreamland Cave World will collapse, so cultivation civilizations do not absorb the dark energy inside."

"Previously, we attempted to supplement energy for Dreamland Cave World by providing electrical and thermal energy, but they were not absorbed by the Dreamland Cave World. This is mainly due to two reasons; first, these two types of energy are not dark energy, and second, the talisman on the Space Crystal Wall can only absorb external energy and not the energy inside Dreamland Cave World."

Yan Fei didn't expect that the energy he frequently used in the Dreamland Cave World was actually the True Origin Power unique to cultivators, and it was even a mutant version of True Origin Power. No wonder he felt like he was a deity when using this energy. He said somewhat uncertainly: "Could it be... you now have a way to replenish energy for the Dreamland Cave World?"

Yang Qi nodded and said: "That's right, through studying the talisman on the Space Crystal Wall, I have unraveled the secret of how cultivation civilization provides energy to the Dreamland Cave World. I previously mentioned that cultivation civilization has huge flaws, but they are overly arrogant, completely unable to see the issues within their civilization. They have reached the pinnacle in utilizing and researching dark energy in the Universe, yet they turn a blind eye to the other energies everywhere in the Universe, resulting in massive waste. I simply applied some modifications and innovations with a Technological Civilization mindset and designed an entirely new Energy Absorption Talisman based on their talisman."

"This Energy Absorption Talisman will be carved on the internal Space Crystal Wall of the Dreamland Cave World. It will absorb the internal energy of the Dreamland Cave World, then convert the absorbed energy into a mutated version of True Origin Power to replenish the energy in the Space Crystal Wall of Dreamland Cave World. With my modifications, this kind of Energy Absorption Talisman no longer absorbs dark energy; they will absorb the thermal energy and electrical energy provided by the Matter Combustion Furnace in the Dreamland Cave World and convert them into the mutant True Origin Power needed by Dreamland Cave World. In this way, we can use the Matter Combustion Furnace to replenish energy for the Dreamland Cave World, no longer relying solely on external dark energy for replenishment."

Upon hearing Yang Qi's words, Yan Fei was overjoyed. For a long time, he's had a concern in his mind, which was the energy insufficiency of the Dreamland Cave World. Due to energy insufficiency, he couldn't open more space channels, severely limiting Yan Fei's ability to mobilize Dream Island's personnel and resources across the planets in the Solar System and drastically slowing Dream Island's development speed.

The most crucial aspect is that although Dreamland Cave World is located in the far reaches of the Universe and attached to the Space Crystal Wall of the Big Universe, it is not completely stealth. As long as someone is willing to pay the time and price, they can still find the exact location of the Dreamland Cave World. Once the spatial coordinates of the Dreamland Cave World are found, those Advanced Civilizations can attack the Dreamland Cave World. When facing others' attacks, the only thing the Dreamland Cave World can rely on is the defense of its Space Crystal Wall.

The defense degree of the Space Crystal Wall entirely depends on how much energy is stored within. More energy means stronger defense capability for the Space Crystal Wall; less energy means weaker defense capability. Once all the energy is consumed by others' attacks, the Space Crystal Wall will no longer have defensive capabilities and will be easily breached by the enemy. Once Dreamland Cave World is breached, Yan Fei will lose control over it, and Dreamland Cave World will change hands and become someone else's small space.
