It was still the highest-level, most binding master-servant contract. That was no joke.
This meant that regardless of their respective ranks or the gap in spiritual power, the master—the Contractor—possessed absolute control over the servant, and the servant could not betray its master.
If the master died, the servant died.
At any time, Shiayar only needed to give the command, "Kill yourself, Lancer," and the Mercury Serpent, as the servant, would have no choice but to stab itself with its spear. Furthermore, there was no limit to the number of times the command could be given.
This was precisely why Beastmasters, when raising their Pet Beasts, mostly chose to nurture them from whelps or eggs. Most mature Pet Beasts, under normal circumstances, would not sign a master-servant contract with a stranger.
Even so, the master-servant contracts Shiayar had with Silver, Shiny, and Crimson were not of this highest level of constraint.
