"It seems I must increase investment in the old officer, to hasten the progress of the demon spirit research." Li Xiu mused privately.
"You don't need to worry, those super spirits are not that easy to rush out. The Trial Gate also restricts demon spirits; the higher the level of the demon spirit, the harder it is to come out, and the greater the damage. So the demon spirits you see on Earth are basically ordinary ones without much quality, because they're the easiest to rush out from the Trial Gate." Old Dao explained.
"Then why was this super spirit able to rush out?" Li Xiu asked.
"It itself is not a super spirit, but twin demon spirits, that merged upon coming out to become super spirit. That's a sort of bug. Even so, it paid a huge price to rush out, otherwise the super spirit's ability would be more than this. Of course, this is my fault; if I hadn't tried to lure it out, actively opened the Trial Gate, and used those things as guidance, it wouldn't have come out so easily."
