Xiang Yu got out of the car and, without a word, slapped Liang Zi across the face with a smack. Liang Zi was not one of Xiang Yu's subordinates; he was just seeking Xiang Yu's help.
Moreover, Liang Zi believed he held a secret of Xiang Yu's and therefore placed himself on equal, if not higher, footing than Xiang Yu.
If Xiang Yu didn't help him, he planned to reveal that Xiang Yu had shot Zhu Qingfang. He was certain that Xiang Yu would be scared, knowing that Zhu Qingfang had many brothers below him who would definitely cause trouble for Xiang Yu to fight for the boss's position.
Liang Zi saw that there was no one behind Xiang Yu, just the two of them, and he wanted to scare Xiang Yu with his words. But, when he saw the terrifying look in Xiang Yu's eyes, he swallowed his words.
