Becoming a Slave!
Ace felt a peculiar Qi wave from the black could inside his martial space and instantly guessed Alvin was using slave contact to imprint this command on Finn!
Ace knew this was the cue and said, "As Elder Brother command."
Now that Finn's face was under that slave item's mask, beside his cold eyes one can see nothing.
Even with the martial sense it was hard to tell Finn's exact expression and this was in Ace's favor because he doesn't have to control his physical expression anymore, and believe it or not, this was the hardest part!
After all, copying someone's personality was never easy, and without Ace's soul probe it would be even harder.
Alvin nodded when he saw the familiar response and looked at Lan with a faint smile, "See, I didn't have any intention to turn him into a mindless slave, and I'm not using the slave contract full capacity. He can cultivate normally, and the slave contract would never hinder him."
