He Ao was never short of Transcendent items with all sorts of strange abilities.
For example...
He suddenly gathered all his strength and repelled Ivier's incoming strike, then withdrew his bone sword, placing his palm behind his back, and a piece of paper emitting a grey glow, resembling a page, appeared in the palm of his hand.
The Forged Pages of Knowledge.
This page could glimpse the most essential knowledge in the world, but one could only ask three questions, and they must not exceed C-level.
This was a reward he obtained the seventh time he officially settled a Copy World, at that time, he asked a question and obtained the formula and rituals for Super Memory and the Magician's subsequent sequences.
Now, he had the quota for two more questions.
While fending off Ivier's renewed attacks, he contemplated his question in his mind.
First, he asked about all the knowledge corresponding to the energy circuit in this hall.
