末振将的弟弟卑爰，本是共谋刺杀大昆弥的主凶之一，率领部众八万人逃往北方，依附康居王国，图谋借用康居兵马兼并两昆弥。汉朝又再一次派遣段会宗，与都护孙建合力防范卑爰。

The younger brother of King Wei, Bi'ai, one of the main instigators of the conspiracy to assassinate the King of the Grand Kunmi, led a force of 80,000 troops to the north to join the Kangju Kingdom, plotting to ally with Kangju to defeat both Kunmis. The Han court once again sent Duan huizong, together with the Protector-General Sun Jian, to counter Bi'ai's threat.
