I said this because I had encountered a similar activation method before, and research on ancient warships had also mentioned opening back doors. From there, I could deduce the result in reverse.
Flying down from the warship, I released twelve floating swords and arranged them around the edges of the back-door area. Then I activated the Earth Origin Artifact armor, allowing its power to link with the floating swords.
At that moment, the primordial energy from the twelve floating swords around me continuously fed back into my armor, making my perception of the surrounding power exceptionally clear.
It was like using a stethoscope to crack a combination safe. Unlocking the password to this back door likewise required the energy-sensing feedback from the floating swords positioned at a distance.
My fingers kept manipulating the energy of the floating swords, bringing the power transmitted by each sword to a delicate extreme. Sure enough, under my movements, feedback from the energy began to appear at the center where I stood.
I took out a high-quality Chaos Stone and began recording the correct feedback patterns into it one by one. After several attempts, I obtained the decoding feedback for the first layer.
However, deciphering the first layer could not truly open the back door. Back doors of this kind generally had several layers of passwords.
But that obviously could not stump me. It was like picking so many locks that one could infer the principles behind any lock by analogy. As long as it was not using the language or techniques of another universe, cracking the remaining passwords was only a matter of time.
Just then, a blizzard suddenly began to fall from the sky. In a season that had been as warm as spring only moments ago, it was jarringly out of place.
