Liu Lili's father was an engineer who fell from more than ten storeys in mid-air at work because of a colleague's improper operation.
When he fell, Liu Lili's father was still alive and all he could think about was his daughter.
However, he did not even get to see his daughter for the last time, and Liu Lili was on her way to the hospital when her father left this world.
That day, Xu Muqing hugged Liu Lili and cried all the time.
Xu Muqing also comforted Liu Lili, saying that the two of them would be together in the future and Xu Muqing would take good care of her.
Xu Muqing took Liu Lili back to her home and the two girls fell asleep hugging each other tightly.
But early the next morning, Xu Muqing found her bedside empty, and Liu Lili was gone.
Liu Lili was taken away by her uncle. Liu Lili did not want Xu Muqing to continue crying and the little girl left with her own uncle before dawn.
She only left behind a letter, which was written in a crooked way.
However, Xu Muqing cried every time she saw this letter, and to this day, Xu Muqing still keeps this letter.
Only, it was pressed into the bottom of Xu Muqing's drawer, and she would never open that drawer.
Because inside that drawer, there were dozens of letters that Liu Lili had sent to Xu Muqing later.
However, Xu Muqing never sent a single letter to Liu Lili.
Because Liu Lili never wrote her address, she only told Xu Muqing in her letters that she was doing well.
But Liu Lili said that every time, but the more she wrote that, the more Xu Muqing didn't believe it, and the bitterness in her heart gradually settled as she grew older.
In the end, it was buried in the deepest soil of her heart.
But this kind of heart feeling can never be erased or melted away.
If it was not pulled out from its roots again and eliminated forever, it would only rot in the soil and eventually turn into poison to erode Xu Muqing's body and mind.
After saying this, Li Hang gently patted Xu Muqing and squeezed his soft hand and said to Xu Muqing, "It's alright, this time I brought you back to help you solve this matter."
Xu Muqing looked at Li Hang with an incredulous expression and said to him, "Honey, have we really gone back in time?"
Li Hang nodded slightly, "Every ordinary person has a chance to go back to the past once in their lifetime, only that this chance is never used by ordinary people."
Xu Muqing jumped up in a hurry after she reacted, and she tightly grabbed Li Hang's hand, "Honey! Then if we really come to the past, can I avoid a tragedy?"
Li Hang nodded slightly, "Yes."
But soon Xu Muqing reacted, Xu Muqing was after all a school master, and her physics was also very good, as well as being very clear about the time paradox.
She hastily asked Li Hang, "If we can really change Lili's father's fate, then won't our future change a lot too?"
Lihang smiled and said, "Everyone has their own piece of time line."
"We all keep moving along this timeline."
"Every time we make a decision, there's a chance that this timeline will diverge."
"And because of this, it has led to the existence of many, many parallel dimensions in the universe we are in."
Speaking at this point, Li Hang suddenly stopped and asked Xu Muqing, "Can you understand?"
