It took ten days of arduous trekking through the rugged, jagged, narrow and twisting corridors of the Broken Gate Pass to finally reach the other side. Most of said time was consumed by the lengthy supply train that was painstakingly lugged by the soldiers across the unforgiving conditions of the pass, where sunlight even sometimes found it hard to breach.
The reason for such hardships is because of the lack of sufficient pack mules and carts for transportation. Why you might ask? Well, with the unexpected increase of soldiers that were not planned for, more food was of course necessary, so utilizing Isaac's expertise, Darius' connections and the wealth Alexander gained from the rebellious merchants, he secured, with the clever usage of several independent traders and merchants, hundreds of tons of high quality food and rations that would not easily spoil from the Yue Dynasty.
