hanaangel_xo On the contrary, he is a very good father. But when Nianzhi was 2 years old, he left her with her birth ( not biological) mother and went to study the parallel world theorie.
After 4 years, he returned but that that bitch of mother ( she is now Prof He step mother) she treated Nianzhi as a lab rat and do every experiment on her.
He got mad. Destroyed her experiences' records and took Nianzhi away. He took her to Prof He house. His mother was a kind woman, she is also Gu Xiangwen best friend. So she took good care of Nianzhi and treated her autism.
But one day, That bitch mother who always sent dolls to Nianzhi ( remember that doll that looked like Wen Shoyi?) But she put some virus in it. When Gu Xiangwen knew this, he rushed to the He house to treat Prof He mother, he also told that Nianzhi is her biological daughter.
Back to the story: Prof He mother has already an old heart disease, and the virus she got from the doll worsened her health.but she didn't want to be treated, she said to Gu Xiangwen that he must erase Nianzhi memories of the past and take her away from that bitch hands.and died.
SO when Prof He and his father arrived,his mother was dead. When they checked the CCTV, they found that the last person who saw her was Nianzhi father. SO, he was suspected of murder.and he fled.
The day of Nianzhi 12th birthday party, that bitch decided to sell Nianzhi to an American laboratory. Gu Xiangwen found out and he made preparation to send her to the parallel world.
She got kidnapped and sent to the airport, but her father took her from there.
The day he sent her over ,he wanted to commit suicide that's why,when he knew that her car has gone to the other World he ignited it and got burned, fortunately, his friend saved his life.
So when Prof He arrived at the place, he saw the car burning with her father, who was a wanted criminal, laughing historically in the fire.
So Prof He hate her father for taking her from him. Because from the day his mother died, he took care of Nianzhi and spoiled her so much. That's why her death was a huge blow to him. He got paralysed for year ( I think) and when he got better, he went looking for her. Even risking his life because there is a theory of the parallel world that two persons who has the DNA can't live in the same place. So if there is He Zhishu in Huo Shao world , that mean Prof He will die as soon as he got there.
But Prof He didn't care because he was about the 12th year Nianzhi.
I will tell you the story about how Nianzhi was born. If you want to know about the friend who saved Gu Xiangwen tell me. Because he is an important character.
Ouf, it was long
