Slave Army versus Undead Army

It was Leo's first time to see that the system or his [Seal Swallowing Ability] was not able to sense the seal even though it was so close to him.

'So, these Slave Seals are not normal. No wonder, he was so confident.'

Finally, Leo realized why Jayden was so confident that Leo could not do anything about the Slave Seals on his slaves.

"What happened? Your talent is not working on them?"

Jayden asked Leo with a slight smile on his face.

'It looks like I have to kill these slaves.'

Even after learning that the slaves around him were not normal and have some super special slave seals that could not be detected by his ability, not to mention erasing them, Leo was not worried too much about it.

Instead, he decided to use his trump cards to kill the Slaves and the Slave Master.
