Two hundred years ago, I was born in the countryside. My father was a noble and my mother was an ordinary woman.
My father, Lord Dong Cheng, was interested with my mother. After she concieved, he married her as his concubine. Madam Yu discovered that her husband had a mistress.
When I was given life, Lord Dong invited a master in the sixth stage. Though that master was bribed by Madam Yu. After being told by a lie, his treatment with my mother and I changed.
Madam Yu finally concieved a child. The birth of the second young master of the Dongs was auspicious for my father.
I continued to train but nothing happened. The hardwork went in vain when I my father told me why.
In the other hand, my brother had progress and was called a prodigy. Then I was despised as a useless brat. Dong Heng was kind and diligent. No matter how his mother brainwashed him, he still cared for his brother.
My mother died because of the exhaustion of childbirth. My sister contracted cold poison but was considered as a genius because of the achievements she had.
Madam Yu then was furious.
After the death of my sister, she blamed me for her death. In fact, she was killed by bandits who were hired by that witch.
That stupid husband believed her and disowned me. Dong Heng was unstable so he believed it with no hesitation.
After days of no food and water, I thought I was going to die. Until one stranger, saved me.
Known as a great master, he gave me a new life as like I was reborn. Huang Peizhi had a wife but no children.
He cured my broken meridians and I finally had progress in my cultivation. In the following years, I became a well-known master.
Still I held a grudge against Yu Lifen. The Dong clan was in crisis because the wife of Lord Dong Cheng offended Lady Xiao Mingzhu.
After decades of not seeing him, my brother came to me and beg me to ask Lady Xiao to forgive his mother. Why would I give mercy to that witch?
She poisoned my mother, killed my sister and making me into her scapegoat. I can never save a woman who deserves her medicine.
"Dong He, will you let hatred blind you?"
My master reminded me. He knew I had a grudge against Madam Yu. Lady Xiao was carrying a child inside her and that witch caused her miscarriage.
The man who has given me a new life, wants me to choose. To give mercy to a woman who killed my mother and sister or decide to ignore my brother's plea.
