What is higher up?
Situated in the troposphere, Chen Yun couldn't help but ponder this as he accelerated upwards.
Although elementary students know that from 0 to 15 kilometers above sea level is the troposphere, 15 to 50 kilometers is the stratosphere, 50 to 85 kilometers is the mesosphere, and 85 to 600 kilometers is the ionosphere.
Beyond that lies outer space, detached from Earth.
But for most people, they can barely explain it.
In fact, they don't have a truly clear concept of terms like troposphere and stratosphere.
Or perhaps even astronauts or scientists don't have as clear an understanding of the actual concept of atmosphere layers as Chen Yun does right now.
Because at this moment.
Chen Yun was ascending continuously through the troposphere with his mere physical body, and he definitely had the most authority on everything about this scenery.
His speed was extremely fast, violently leaving many traces behind.
