The recording cut off after the red-haired man uttered those words. Xiao Gun's eyes were slightly reddened, welled up with tears, his gaze transfixed on the area where the projection of the red-haired man had been. Yao Chang had also been looking at the same spot with trembling lips, which perfectly displayed how distraught he was.
Finding the dragon's gate was a phrase they coined during their period of captivity. At the start, it was used as some gimmick, something they said for a laugh. With how bleak things were, humor was their way of maintaining their sanity.
Then after they escaped, the phrase sort of stuck with them, only this time it wasn't used as a joke. Every time before they ventured into some dangerous location they would utter those words, "May we find the dragon's gate."
