On the night when the entire Tiance Mansion was massacred, seven-year-old He Lanci only did one thing - stay alive.
Ten years later, she swept across the northern border with an unsheathed sword, killing those who deserved to be killed.
People in the world call her the "Ruyi Jinghong Sword", saying that she is quick with the sword, cold and cruel.
No one knows that her murderous sword skills are the lost secrets of Tiance Mansion.
No one knew that every name on her murder list was related to the murder case ten years ago.
Until she met Xiao Lin.
The young master of Tianji Pavilion has disabled legs, but he holds the largest intelligence network in the world.
He sat in his wheelchair and said to her: "I can help you find the person behind this."
She said: "What's the price?"
He smiled: "Do three things for me."
The first thing is to kill someone.
Second, find something.
She hasn't thought about the third thing yet.
He Lanci thought this was a deal.
Later she realized that she had been in his game from the moment he opened his mouth.
And in this game of chess, the whole world is at stake.
Purpose: Chaotang Jianghu, revenge, growth, mutual support
