Therefore, from Kushan's perspective, the Wuxi Colonel stationed in the Western Regions is equivalent to the Han Empire's garrison in other countries, although many Kushan nobles think that since they've not heard news about the Wuxi Colonel for years, it's possible the Han Empire's garrison is no longer present.
Of course, due to the battle fought over the past century between the Han Empire and the Northern Huns at Mount Houtian, which inflicted some serious damages, the Western Regions have been somewhat neglected; if not for Li Jue having gone over, it's likely only a thousand Tuntian Army soldiers would remain of the Wuxi Colonel's garrison.
Thus, Kushan's perception wasn't actually wrong, but the impression of Emperor Yano Gaozhen's battle was too profound, leading Vasu Deva I, after advancing into Central Asia, to halt and send a diplomatic mission equipped with telepathy to the Western Regions.
