As he ran, his body automatically fine-tuned his posture, complying with the airflow he encountered, instinctively reducing air resistance to the limit.
"190? No, it should be around 200."
Xue Jing used the backward speed of the scenery in his field of view as a reference to estimate his current speed.
He could basically confirm that he had reached a level of 200 kilometers per hour.
This was already comparable to a high-speed train, a superhuman speed!
Converted, that's about 50 to 60 meters per second.
"If I were to channel energy at full strength, I should be able to increase it by about one-fifth."
Xue Jing thought to himself.
The speed of running, due to the reason of air resistance, had a severely diminishing marginal effect.
On Earth in his previous life, once elite track and field athletes entered under ten seconds for the 100 meters, every 0.01-second improvement was considered a dramatic progress.
