Breaking the sound barrier with the physical body is not just a record of competitive running, but an exemplary demonstration of the transformation of a life's state.
It signifies that the human flesh and blood can break free from the constraints of physical laws and reach for domains once only belonging to iron machinery or mythological legends.
However, recalling the thrilling experience just now, Fang Cheng still finds it a bit too stimulating.
The challenges of breaking the sound barrier are comprehensive.
First is air resistance; the faster the running speed, the more pronounced the viscosity and compressibility effects of the air become.
The oncoming airflow is no longer "wind" but a "wall of air" that is violently compressed and extremely dense, drastically increasing resistance.
Next is the "heat barrier effect," where high-speed movement results in intense friction with the air, generating immense heat capable of roasting flesh.
