I want to know what the future holds for the protagonist's sister

His words were not bad, but i didn’t know if his sister would be happy in the future. Right now, the protagonist’s life was very short and he had to busy himself with cultivation, so it was very important for her to maintain his family. However, once the main character shows his prowess, material life will no longer be a problem. Then, how will this sister continue to play the role in this book? Most likely, the best course of action was to leave the protagonist and go to a high level place to train, waiting for the protagonist to come find her. There were too many novels like this. After the poverty story ended, the heroine became completely useless. I wonder if this book will be the same
