And so, ten years quickly passed.
Both Experimental Islands had made major progress. After all, they had the young Skinny Guy's cheat helping them.
All they had to do was keep conducting comparative experiments.
They replaced the brain cells of one wanderer after another, then compared their conditions before and after to ensure there were no problems with their brains.
As a result, they made great strides in the field of Brain Science.
Simply put, they replaced brain cells related to memory bit by bit.
After replacing a small portion, they used the memories stored in other brain cells to connect the previous memories together.
There was also an even simpler method.
That was to have the Wanderers write down everything they remembered little by little.
They wrote down every single detail.
After each cell replacement, they memorized everything again.
The entire process progressed smoothly.
In the researchers' eyes, there was no problem with this.
Human consciousness depended on the brain and memory.
If neither of those changed, then consciousness would naturally remain the original consciousness.
It was like someone losing some memories after sleeping. You could not say that person had changed.
There was no such thing.
However, when the protagonist saw this, he could not help shaking his head at the young Skinny Guy's research.
This fellow was still too naive.
Or rather, those researchers' understanding of Brain Science and consciousness was still far too shallow.
They had all forgotten that human thought and consciousness possessed a truly peculiar aspect.
The world he was in was a materialistic one.
That meant the brain's unique shape and structure directly determined consciousness itself.
Human consciousness consisted of two parts. The first was software, and the second was hardware.
This was practically an axiom.
It was common knowledge, and deductions could
