Enemy's Enemy Is a Friend (I)

"You are... glug glug... cough cough..."

Yan Lingji, whose cheeks Ye Qingcang had pinched, struggled and shook her head. Of course, it was not a refusal; she was trying to shake off Ye Qingcang's hand from her face. With the water helping and Ye Qingcang voluntarily letting go, Yan Lingji did manage it.

It could not be helped.

They were underwater.

Breathing freely underwater was nothing but a fantasy.

But life would always find a way out for itself.

They had already been locked in here.

There was no point considering whether it was possible or not.

Find a way, and live. Fail to find one, and die.

Thus, internal breathing—using Internal Energy to replace normal breath circulation, extending breath-holding time as much as possible, supplemented by the weekly water-changing and breathing opportunity—was the simplest and most efficient solution.

Before Ye Qingcang had transmigrated.

Back in that world without anything supernatural.

The record for holding one's breath was twenty-two minutes.

It was utterly impractical in reality, since no real environment would provide anyone with pure oxygen. The proportion of oxygen was fixed, so the twenty-two-minute record achieved under natural conditions was more realistic.

But the human
