Lü Bu behaved arrogantly in front of Yuan Shao because he perceived that he had done the Yuans a favour by slaying Dong Zhuo. He belittled Yuan's followers and treated them with contempt. He once asked for more soldiers from Yuan Shao but was refused, after which he sent his men to plunder Yuan's territories. Yuan Shao was greatly displeased and felt that Lü Bu posed a threat to him. Lü Bu sensed that Yuan Shao was suspicious of him so he wanted to leave northern China and return to Luoyang. Yuan Shao pretended to agree and recommended Lü Bu to take up the appointment of Colonel-Director of Retainers (司隷校尉) while secretly plotting to kill him.
