The [Profound Immortal] medallion, in addition to the two major functions of Thunder Tribulation and Melt Devouring, has also added the ability to extract lifespan.
Since it's extraction, not plundering, from the literal meaning, one can somewhat understand its specific function — as long as one obtains permission from others, they can extract others' lifespan as an equal exchange.
If someone is willing to give up one day of lifespan to Zhao Guanlan or Ma Ran, then...
The lifespan Ma Ran gains is one day.
There's no possibility that "since life levels are different, one day of lifespan would be reduced to one second for Ma Ran."
So...
Overall, the most defying function of the [Profound Immortal] medallion is that it gives Ma Ran the possibility of immortality.
Yes.
Immortality!
It's not as simple as longevity and vision.
