Why did Linglong teammates get their throats cut?

In order to solve Mark's problem, Charles also secretly threatened 4068 to kill Mark on the field with 4277, and 4068 cut Mark's throat on the ground.

When Mark narrowly escaped death and returned to the lighthouse, Charles always stressed that Mark was no longer a man. At his instigation, Victor almost took Mark away and got rid of him. When he came to power, the only way to give Mark a chance was to let him travel far away. He also told Ran Bing that Mark's dignity and life could only take away one.

Charles kills and kills.

Mark's throat was cut from the beginning, which was carefully planned by Charles. Mark, whose throat was cut, survived by spine method, and Mark became an orc. Under normal circumstances, after Mark became an orc, he should not pose a threat to Charles. But Charles didn't let Mark go. He still persecuted Mark in various ways.
