Zhou Ning and Liu Yongxin, with arms folded, watched the interrogation room. Just by looking at Liu Tiesong's condition, they could tell that the man had been tormented all night. He was somewhat listless, yet his face still bore a look of disdain, completely unconcerned by Xu Dayuan's questioning.

It seems he's absolutely sure that as long as he refuses to admit anything, the police can't touch him. Moreover, this attitude makes it easier for those outside to find opportunities to interfere," he said.

Zhou Ning nodded. He knew this all too well.

Just as he was thinking, his phone rang. The caller was Xia Shouchang. Seeing the number, Zhou Ning's brow slightly furrowed. Could it be that he too was calling to advocate on Fang Shengping's behalf?
