Ultimately, it was his incompetence that led to him and his sister being deceived by Feng Linyu, which is why his sister is in such pain now.
He had to protect this house, and to do so, he had to become very strong and couldn't live under his sister's wing anymore.
Even if the very capable doctor that Madam Gu spoke of couldn't cure him, when his sister got married and had children, he could be a strong support for her.
Having a strong maternal family is the most powerful support for a girl after she gets married.
If he were strong, his sister's future husband would fear him and wouldn't dare to bully his sister.
He looked into Feng Yushang's eyes, speaking each word very slowly and seriously.
He talked for a very long time.
Gradually, Feng Yushang was persuaded by his reasons.
If she could, she still wanted to keep her brother by her side.
But she could tell that her brother had made up his mind to leave.
Perhaps her brother was right.
