The sacred flame was introduced into China from the Persian Catholic Church. There are twelve * * *, which were painted by Huoshan, an old man in the mountain (you can go to Baidu, this person does exist in history). Six of them are engraved with the martial arts secrets of the old people in the mountains, which are in Persian, and the other six are blank. After they spread to China, they were used as the imperial edict of the founder of Zoroastrianism, engraved with ""on six blank spaces.

By the way, the flame stage is also one of the few things in "The Dragon Slayer by Eternal Adversity" that can rival the Dragon Slayer in strength.
