Actually, the biggest flaw in Qing Chen's plan was these three people.
All it would take is one person to reveal information to the Future Organization, telling them that it was Qing Chen who had taken control of Capri, and then the Future Organization would quickly realize all the cause and effect that led up to this.
It was that simple.
However, Qing Chen had no intention of killing them to silence them.
Although those three hadn't been of much help, at least they hadn't done anything to harm Qing Chen or Yaoyao.
This was Qing Chen's bottom line—if he resorted to indiscriminate killing just to keep this secret forever, then he would not be worthy of calling himself a Knight.
Originally, Uncle Li Dong had waited a full eight years to gather 3,650 people deserving of their fate just to meet the requirements of the Heaven and Earth Chessboard.
That master, even when imprisoned, had never abandoned his principles, and Qing Chen naturally couldn't either.
