This is a very good series, I'm glad I stumbled on it.

Thank you for translating!

I'm not a scientist but how could there be still oxygen that deep in the earth? There could still be some but wouldn't it be thinner? 🤔 won't they have a harder time breathing?🤔

@Stoffelvandoorne If their depth is accurate, the air pressure would be around 100 times bigger then at sea level, you can probably cut oxygen supply in 3 and you wouldn't feel a thing, since you lungs contain 100 more times air then on the surface.

found something interesting online: The maximum pressure for long term survival in an atmosphere of 79 % nitrogen and 21 % oxygen is limited by oxygen toxicity. The limit of the partial pressure of oxygen is about 0.5 bar, the maximum pressure therefore is about 2.5 bar. For only some hours the pressure may be 4 to 5 bar, but nitrogen narcosis might be a problem. For higher pressures the amount of oxygen and nitrogen in the mix must be reduced and replaced by helium. For a total pressure of 5 bar, the amount of oxygen should be not more than 4.2 % but not less 3.2 %. The partial pressure of oxygen is then again 0.21 bar like that of normal air.
For deep sea saturation diving, a pressure of about 60 bar was survived for weeks in an atmosphere of oxygen and helium.
