In fact, when Sheni Pei said these words, the Parthian Emperor had also set the tone for the Parthian generals, which was to treat the Han Army as an ally, but the Han Army is the Han Army, and Parthia is Parthia.
While relying on the Han Army for development, it is more important to strengthen one's own strength. Vologases V is not foolish, he indeed regards the Han Army as an ally, but he is very clear that what belongs to the Han Army does not belong to himself.
As an ambitious and capable emperor, the greatest tolerance of Vologases V is for others to become an emperor just like him.
As for subservience, it is completely impossible for him, so although Vologases V values the support of the Han Dynasty, he cannot lower his status.
This is also why Vologases V requested Li Jue twice, but went to Armenia with his troops before Li Jue's arrival.
