What was the greatest achievement of the Holy Spirits—or rather, of the Saron Civilization?
If Chu Fei had to say, he believed it was transforming flesh-and-blood bodies into Holy Spirits.
Even now, Chu Fei had no idea how the Saronians had accomplished it back then.
With Chu Fei's current research capabilities and accumulated knowledge, he could work out the general principles behind many things with only a little investigation.
Take the earlier "Entropy Increase Bomb," for example. Based solely on the aftermath of its explosion, Chu Fei could analyze its approximate principles. Though merely knowing the general principles still did not enable him to manufacture an Entropy Increase Bomb, it at least gave him a direction for research.
As the saying went, if you dared reveal a health bar, even gods could be killed for fun.
The same applied to scientific research. As long as the principles could be found, humanity could gradually work its way toward the final technological product.
Yet Chu Fei had no clue whatsoever how the Saron Civilization had transformed flesh-and-blood bodies into soul bodies. It was an incredibly fantastical technology.
This had not been done to one or two people, but to an entire civilization. They had even created a Gaia Secret Realm.
Still, Chu Fei had some guesses regarding the prerequisites for this technology. He always felt it had been a cry of despair—back then, the Saron Civilization had been driven into a desperate situation. Either they erupted in desperation, or they perished in it.
The many imperfections of the Holy Spirits were also enough to prove that the technology had been developed in great haste.
But whatever the reason, one fact could not be denied: transforming a flesh-and-blood body into a soul body was truly, incredibly impressive!
Now, Chu Fei had finally found
