Ao Sai's evaluation of these forms of immortality was that the ancient Super Civilization's three experiment bases created various ways of achieving eternal life, yet most forms of immortality were flawed, such as vampires who could not walk under the sun, or Sea Ghosts who could not leave the ocean.
Gu Fan became puzzled, "Isn't there a perfect form of immortality that was created? I've seen it, the big boss and Zhuo Hang possess it."
Ao Sai shook his head, "The price of this perfect immortality is simply too great, and the conditions are extremely harsh, sacrificing twelve to achieve it for one."
Gu Fan thought about it and realized it would be impossible to popularize this perfect form of immortality on a large scale.
Ao Sai added, "But the Destiny Stone led you to those three experiment bases, let you witness the capabilities of our ancient Super Civilization, put you through so much, have you comprehended anything?"
