Is everything in the history books true?
In the 21st century, they are the four killers of "Arashi", the most feared killer organization. However, as killers, they have never really killed anyone, except for their leader, the person who manipulated them.
When they returned to the Qing Dynasty, they were just looking for some peace and quiet. Unexpectedly, God would not give them this opportunity. Is it really their fate to meet these brothers? Why are these brothers who are obviously close friends described in history books as fighting each other? Could it be that their appearance disrupted everything?
Okay, in that case, whether you are an elder brother or a commoner, your future is ours!
