What Noah said left Li Chen struggling to process it.

Under normal circumstances, Noah would not have needed to explain any of this. Li Chen could have figured out those principles himself.

But in reality, although he had awakened at this moment,

his body was still completely empty, with barely any energy left.

And the extreme lack of energy meant that only a very, very, very small portion of the cells in his body could remain active.

They were slowly dividing and regenerating, helping him recover some basic cognitive abilities.

The vast majority of his remaining cells, especially his brain cells, were still dormant or on the verge of death.

Brain cells were the key to humans possessing self-awareness, thought, emotions, and other higher neural activities.

They gave humans abilities such as language, writing, invention, and creation.

Those cells could not perform their original functions or effectively transmit nerve impulses.

That was why Li Chen's thinking had become so sluggish.

In fact, this principle was not all that different from ordinary people.

An ordinary Earth Human

had roughly fifty to eighty billion brain cells.

Yet 98.5%, or even 99%, of them remained dormant for extended periods.

That was because the human brain did not receive enough energy to drive those cells and stimulate them into activity.

The total number of brain cells,

as well as the number of active brain cells in the human body,

often determined a person's intelligence, memory, and other qualities.

In other words, the greater the total number of brain cells,

and the greater the number of active brain cells,

the smarter a person would be.

Their memory, learning ability, comprehension, verbal expression, ability to invent and create, and so on would also be more outstanding.

Conversely, if someone had very few brain cells in total,
