The two main factors that necessitate waiting until Lu Xuanyu becomes a mature Benchmark Man before testing cyberization are as follows.
One is the acquisition of neural signals.
Over time, certain proteins accumulate within neurons, while some metal-based proteins become integrated into the cell membranes composed of phospholipids due to the metabolic turnover of the cell membrane.
These changes gradually alter the characteristics of the action potentials of neurons.
Of course, this all happens imperceptibly.
According to existing records, a newly-emerged Benchmark Man only feels that as time goes on, their neural reflexes become faster, and their thoughts spin quicker.
The performance of the human brain will improve to a certain extent.
This kind of change only occurs at the cellular level and doesn't significantly alter the structure of the neural network. Therefore, its impact on human self-consciousness isn't too substantial.
