Hello, I am looking for a manhua whose name I forgot. The story was something like this:-

1.The MC's mother is sick. He goes to some school to become knight and the food/power-up medicines he get, he gives it to his mother instead of consuming it himself. This makes him weaker to advance to next class but he keeps working hard. His mother lives alone. The father's details are not known but later it was found out that his teacher was his father. The mother and father reunite later.

2. When he was small, he also saves a green (or purple) haired girl against some people who were chasing her by helping her hide behind the bushes. She was mute that time. Some guy comes and takes the girl with him and hits the the MC so he goes unconscious. Then the guy asks the girl to accompany him but before she does, she puts a "forget me not ring" into his finger.

3. Years later, the MC meets the girl again during a fighting tournament outside and this time she is blind. She recognizes him because of the "forget me not" ring, however; the MC does not. MC asks her if he could accompany her so he can take her home everyday after the tournament finishes. And they spend time together like that.

Nvm found the manhua now. It is Shen Yin Wang Zuo
