Zhou Yanxu did not know the emotions of Zhou Yanbai.
His body was weak, so he had to exercise to strengthen his physique.
He had given some money to Jiang Nanshu's current parents, asking them to take good care of her, and had someone monitor the situation there. Driven by the interest of money, Jiang Nanshu's parents would treat her well, at least ensuring her survival during her early years.
Zhou Yanxu simply wanted to protect her from the shadows, waiting for her to grow up safely before he could leave.
However, he still underestimated the ugliness of human nature. When Jiang Nanshu was eight, he heard that her parents had chained her up and planned to sell her to a widower in his forties from the village.
Over the years, the news he received was that Jiang Nanshu was doing quite well; her parents no longer troubled her but rather fed her, allowing her to grow up safely.
Why would her parents do such a thing when there was money involved?
