Even though Jayden had the numbers and enough strength to conquer the world, it was useless in front of Leo because they were unable to catch him, much less injure or kill him.
'I think it is better to escape from here with the rest of the slaves. As long as I am alive, I can take my revenge against him.'
This was what Jayden thought upon seeing how easily Leo was able to take care of his slaves.
Even though Leo was not killing his slaves, they were useless for Jayden for the moment because they were unconscious and even if he engraved new slave seals on them, they were not in a position to fight Leo.
'It is better to save my energy and come back another time to take my revenge against this b*stard.'
Engraving a special seal like the [Growth Enhancing Slave Seals] costs Jayden a lot of his energy and he didn't want to spend that energy now because Leo could erase the slave seal with a single look.
