Qiu Tu hadn't been bragging in front of Liu Fuping. Yesterday, when he spoke on the phone with Liu Xiongyuan, he indeed conquered the old man in just 1 minute.
While Liu Xiongyuan obviously doubted the source of Qiu Tu's information and his capabilities, Qiu Tu took over the phone call with Liu Xiongyuan and said just one sentence.
"Nevermind whether I'm using you as a cat's-paw, nor who the real culprit is. Since both of them are suspects, how about I help you kill them both?"
With just that simple sentence, Liu Xiongyuan was willing to continue the conversation with Qiu Tu.
Qiu Tu spoke very directly in his conversation with Liu Xiongyuan.
After piquing Liu Xiongyuan's interest, he immediately asked a question, which was to what extent was Liu Xiongyuan willing to go to avenge his son's murder.
Liu Xiongyuan's answer was also very simple. That was 'Life'.
Given that, Qiu Tu didn't hold back. He frankly told Liu Xiongyuan that he wasn't sure who the real culprit was.
