The new reborn Meryl was indeed much stronger than what Khan remembered.
Khan had been going back and forth to the human world but didn't sense Meryl's existence at all.
The female elf was an expert at concealing her power and hiding from him.
If Khan had known that Meryl was still alive from the start, he would have hunted her down and killed her with his own hands.
Even so, Khan still dealt with her as casually as if he were dealing with a child.
Meryl did get more powerful, but so did Khan.
If Meryl couldn't escape Khan fifty years ago, it's the same now.
Meryl groaned in frustration and threw a dagger at Khan through her eyes.
"How did you do it?"
"I've known someone's been following me these past few days. I even waited for you guys to ambush me until I got bored. I've already cast a spell on you, and my illusions trap you."
