Gu Yi'an put down the phone and submerged herself completely in the water, letting the warm water cover her head.
Asphyxiation gives people an unexpected pleasure, a feeling of approaching death.
Therefore, the moment of death is not painful; more often than not, it is a transcendent pleasure.
Of course, Gu Yi'an would not die.
She knew how to swim. Generally, people who knew how to swim would find it difficult to succeed in drowning themselves because the process of asphyxiation, especially at the initial stages, was very unbearable.
Instinct would make people escape from this distressing sensation.
And once one endured this unpleasant initial phase of asphyxiation, what followed was hallucinations and pleasure induced by the lack of oxygen. By this stage, if a person did not snap out of it and was deeply mired in it, there would be no saving them.
