Douluo Starts with a Sword

I don't quite understand it. Did the male protagonist not read this book before traveling through time? Douluo Continent? But some of the sentences made it seem like he knew it, and I was a little confused. ​ The male protagonist is really as stupid as his name suggests, he feels silly and has no scheming. ​ ​There is also a plot of traveling back in time from modern times, and if the male protagonist is set up to be an upright character with only one woman, he should not always have various women around him and then give him a hug or a kiss on the cheek instead of helping him. Especially Zhu Zhuqing, who is always by the male protagonist's side. The male protagonist keeps stroking his cat and is very speechless. ​ In this way, the male protagonist's character is always emphasized. It's too tough and awkward. The same goes for the female protagonist. I don't like this character very much.
