The Search for Crossing the Rivers and Lakes of Qilu

My name is Zhang Xiaoyi and I am a retired soldier. On a magical night, my sister, who I had depended on since childhood, disappeared mysteriously. After two years of searching to no avail, until that time, an ancient ship appeared in the depths of the Bohai Sea... History seems to have suddenly turned a corner in a familiar dynasty and moved towards a strange parallel time and space. I don't know why the world has become like this, and I don't know if it has anything to do with my sister's disappearance. Maybe this is what everyone calls time travel, haha, it's just a world that has changed time and space and is still cruel. The elusive beauty with the jade flute, the small business owner of the sect, the hypocrite with a big family and a big business, the double-faced daughter, as well as the divine island, the sand monster, the puppet soldiers... During the killing night at sea, they thought I was prey like everyone else, until I took out the equalizer of all living beings. They said that my sister may be the mysterious woman who appeared in the Confucius Temple in Qufu twenty years ago, or she may be Linghu, the number one killer in the world more than a hundred years ago. I'm convinced... What a bullshit clue this is. I traveled all the way across here just to hear this? No, no matter what the world is like, my original intention has never changed - to find my sister, no matter where in time and space she is.
