Back when the "Lord of the Sky" led his army to break through the Neanderthal tribe's Supreme Council, the spoils of war naturally included technology related to the "Stargate."
However, the "Dimensional Gate," which relied on Longinus' positioning, proved more practical, safer, more reliable, and easier to maintain and manage compared to the "Stargate." There was no concern of randomly projecting to other places, so the fall of the "Stargate" wasn't solely due to the rarity of manufacturing materials or the complexity of coordinate calculations.
Over the past forty years, as the "Stargate" had not appeared, the time had become so long that Chen Fei subconsciously ignored what had happened back then.
So even if the "Lord of the Sky" never used the "Stargate," it didn't mean there was no possibility of it being used at all.
No one expected that the "Halo" on Cangqiong Star's side was not only a "Dimensional Gate" but also had the traits of a "Stargate."
