Li was an ordinary person from the Dahua Empire. After joining the military at the age of 29, he lived a life of getting by and drawing a salary. To him, being a soldier was just a profession, as the Dahua Empire had not given its soldiers any sense of purpose to fight for.
The soldiers of the Great Tang Empire bore the responsibility of history; they defended their own happy lives and sought to liberate their oppressed and enslaved brethren, so they had a cause to fight for and the conviction to forge ahead.
It must be said that the propaganda machine of the Tang Empire performed exceptionally well; the soldiers of the Tang Empire genuinely hoped they were doing the right thing.
Since the Tang Empire had implemented a series of reforms, even judging superficially, the Tang Empire could indeed be called the light of the world, and the wars it waged did seem to be rescuing the masses from dire straits.
