Klaus continued forming hand seals, twisting his fingers into complex patterns. Luna and Nuna watched closely, fascinated by what he was doing.
The seals were something taught to him by the senior, who offered him many options to choose from. He even offered to teach Klaus how to place a slave mark on the twins, but for some reason, Klaus hated that idea, which surprised him.
The thought of turning someone into his slave didn't sit well with him, no matter how practical the idea was. So he chose to use an old-fashioned seal called trust.
Choosing to trust the twins seemed like a foolish idea, especially since they were assassins sent to kill him, but Klaus wanted to trust someone. They seemed like the logical choice.
If they turned out to be like their mother, he would rather kill them than make them his slaves.
After forming hundreds of seals, a purple runic diagram appeared on the ground, radiating a powerful aura.
