A few days later.
Karl was sitting in front of Richard's grave. His bodyguards, who had been protecting him this whole time, noticed the change in Karl. This might be the first time they saw the prince being this sad after losing someone.
It was truly a lot to take that day. After finding Richard getting killed, the base was in chaos. Richard was the hope that could strengthen them, yet, someone actually killed him brutally.
After that day, the prince asked them to investigate the matter. And there was only one living witness who didn't die in that attack. She was Richard's bodyguard.
The prince was so mad that he wanted to kill her, but she was the only one who knew about the murderer. Even when he tried to investigate the cause, there was no clue or whatsoever. All the surveillance cameras actually didn't pick anything.
Hence, he had to keep Richard's bodyguard alive and ask her as soon as she woke up.
