The Villain's Journey as a Hero

I think the plot is okay, I voted first, looking forward to the new plot version

If forced transformation could be used to transform all the people in the opposite world into the physiques of people from the knight world, wouldn't it be non-combat reinforcements? As the number of people increases, the consciousness is rewritten, just like other gods, not directly, but always changing the subconscious. So why did the last one say that Cao Zhijing is dead? It should be that it means that the fighter is gone and is now a Kamen Rider, and his consciousness has been rewritten.
