The Zhou Family's trade convoy used a Soul Device known as the Soaring Divine Shuttle, likely a product from a unique Secret Realm associated with the Fantasy and Xuanhuan genres. Its speed was extraordinarily fast, even surpassing the speed of sound.
Wang Linchi was not exactly sure by how much it surpassed the speed of sound, but he was certain it did not reach light speed.
If it truly reached light speed, using it for trade would be impossible.
Given the Soaring Divine Shuttle's speed, it rarely fell victim to robberies, as flying through the sky made many nefarious activities inconvenient. This was also a testament to the resources of a Big Aristocratic Family.
Of course, that was the situation in the past; that certainty didn't extend to the present. After all, the events in Yingzhou and Yi State had thrown the world into chaos.
