Kyle waited until this interrogation was over. The giant man was clearly a demon of some sort because all the skills he used were charged with demonic energy.
The general that was being interrogated was crushed, and Kyle that hated to see his man suffering like that, couldn't do a thing. He could only shut his teeth and wait. Wait until the demon goes away, and finally, he would be able to free his comrade.
Every slash made on the general's body, every remark that was said to the man, even the hallucinations that the man experienced under the spells of the demon didn't make the general say a word about who he is or what their plan is.
Kyle felt every single strike and everything as if it was being done to himself.
Clenching teeth and fists, Kyle wanted to go out and save him straight away, but even teleporting to the underworld would kill the man in the instant. There was literally nothing that he could do.
