Wu looked at Feng Yi with a serious expression, "So, if you encounter an emergency situation and you need to save someone, please be sure to pay attention to the problem of rapid speed changes over a short period of time. An average person can't withstand it, so be mindful of safety protection."
"That kind of lightning-fast rescue of a person standing in one place and then stopping instantly at another place in movies is inimitable. Otherwise, the rescue could send someone directly to meet the King of Hell on the spot."
"Humans are both strong and fragile. It's not that humans can't create transportation or aircraft that are faster than existing ones, but that the human body can't withstand it."
After saying this, Wu added, "Of course, if there's some mysterious power beyond my common knowledge that can safely allow someone to withstand sudden changes in speed, then that's a different story."
The very existence of Feng Yi's race was beyond Wu's common knowledge.
