Where have I seen this sentence:
"Time and space are opposites, and there is also a 'you' in another time and space."
Maybe this is true, or maybe this is human fantasy. But she happened to see this spectacle.
But what will happen to you when "traveling through time and space" that only appears in novels happens to you?
A 21st century Western medicine doctor travels back to the bloody era of martial arts. He transforms from a martial arts prodigy to a useless person, from a future master to a low-level disciple. Different troubles continue to arise along the way. From time to time, he is taken advantage of by others, and people come to challenge him at every turn. Life is always in danger of dying, and the head is hung on a belt.
Faced with this, Yu Shang could only shout: "I'm just a useless martial artist, why am I in so much trouble!!!"
