Under the explanation of Lu Yang, everyone finally understood they've made a big mistake, what they've been studying for a good while as a black Golden Core was not a Golden Core at all.
It was not really their fault. The Mount Pig is full of gall, but gallstones only happen in Golden Core Stage and above. The Five Heroes of Eagle Mountain hadn't had any contact with Golden Core Stage Demon Beasts before, so it was understandable that they didn't know.
The key point is, who would imagine that a Gallstone could emerge in the Golden Core Stage?
"This is very normal." In response to Lu Yang's inquiry, Fairy Eternity stated as a matter of fact, "Ordinary people get ordinary Gallstones, so naturally those in the Golden Core stage get Golden Core stage Gallstones. Totally reasonable."
