And not the first time stuff like this is happening in drama world. Can we all please be serious. They copied one drama, nope sis or bro whichever you are so sorry I don't know you, but a film or drama copying straight from the book, anime, or donghua version is not a one time thing done by a very popular film or drama. There are a lot less popular dramas that have done it and a drama being popular doesn't depend on the donghua or whatever if adapted. Sometimes it depends on luck because I see some certain dramas being popular and I'm wondering okay it is not that good why popular?
The Land of Warriors is good, yes they might have copied 90% of the storyline but I still love it. It is not lazy writing but they probably want to give the original fans of the donghua something. And they made me fall in love with the donghua version because when I watched douluo continent it was so different and I dropped the donghua after 5 episodes but I'm almost through with it now because of The Land of Warriors. Soo a vast difference in opinions, besides it is called a live adaptation. If you feel it is not for you best to drop it.
And I'm sure you realized filming must have started and finished way before it was released. There was even rumors it was supposed to be released in August but censorship and stuffs.
