Kai didn't stop the movement of the knife; instead, he picked up another one and placed it over the son's neck.
"NO NO NO, I will tell you everything, just let them go, please sob sob yes, I was one of the people who went to kill her. I will tell you sob everything I know, so just let her go."
The guard began to cry, feeling helpless, as Kai was about to kill his wife and little son.
Pulling the knives away, Kai stood up and jumped in front of the guard. He put away his knife and asked, "Then tell me, who was it?"
"I... don't exactly know who among the Lopez family was involved, but..." After a brief pause and releasing a tired sigh, the guard added:
"Kevin was the one who assembled all of us, he paid us and forced us to do this, I swear I would never have done it. Kevin seemed to have received direct sob orders from someone in the family, please spare us."
