Unauthentic!

After hearing that, Karlos was angry as well as frightened. He didn't want to lose his brother, especially now that he had accepted his criminal identity. He even wanted to make his brother join the same organization as him so that he could help him get stronger and get the same benefits as him.

'If only he hadn't taken William hostage! I would have killed him already!'

Karlos gritted his teeth in frustration.

Luis smirked. 'As I expected. He doesn't dare attack me, but this also ruins the fun.'

"I'll give you a chance. If you can defeat me. I'll let your brother go."

"Are you serious?" Karlos asked with a deep expression.

'Of course not.' Luis chuckled inwardly but still answered with sincerity. "Yes, I never go back on my words."

"That's what you said." Karlos clenched his fists and a maniacal grin appeared on his face. "Don't regret it later."
