Walking there by himself would be a waste of time, and Chen Mobai didn't know the way.
He was curious to experience the Teleportation Array, but the cost of ten Spirit Stones was simply too high.
So, he was left with the option of joining a caravan, which would only cost one Spirit Stone, albeit taking five days on the road.
Southstream Market was managed by four prominent Cultivator families: the Liu family, the Wu family, the Lou family, and finally, the Luo family that tamed the Spirit Camels.
It was possible for Foundation Establishment Cultivators to fly for long periods, but those were the pillars of their families - it would be too demeaning for them to transport goods.
Hence, Spirit Camels were raised, which could grow up to Rank-2, having great endurance, capable of travelling a hundred miles a day, carrying a load of a thousand pounds, and running for seven days and nights without rest.
