The Lord and the other seven demons are collectively called the eight demons. They are still eight brothers and sisters. Although their relationship is not so good, they still ruled the whole world together in ancient times. That is to say, the demon king and other demons are equal, and their strength is basically the same. Otherwise, in the devil's style, I would have killed other demons and ruled the world by myself.
Eight demons have their own unique attributes. The Lord is a fire demon, that is, playing with fire. Other demons also have their own abilities, such as Tian Yue's wind, thunder, water, earth and mountain fires. These eight attributes are also the innate abilities of these demons.
Eight demons are equivalent to eight divine powers, but the Lord has twelve spells, which looks even more powerful. Because in the final finale, after the Lord got the twelve spells, he could actually hang the demon dragon with the eight magic spirits. Although Yao Xiaolong gave some of his strength to Bing Bing, he left most of it.
Twelve spells have been destroyed, and the magic of spells has returned to primitive animals. Only the power of dragon magic, because there is no dragon in this world, and there is nowhere to go before Daolon Wong resurrects the Lord. This shows that the magical power of the spell originally did not belong to the devil. If the power of the spell belongs to the Lord, then the spell should be returned to the Lord after it is destroyed, not the animal. These forces should have nowhere to go like the magical power of the dragon curse, and will not run to the dragon until there is a dragon.
The mouse spell gives life, but the Lord doesn't necessarily need it. God was once resurrected by Daolon Wong without a mouse spell, and finally by his father without a mouse spell. When the Lord was defeated by Lopez, he was fascinated by the magic of petrification and pulling away the magic power. Moreover, this petrified magic seems to be permanent. If the Lord wants to regain vitality, he needs the power of mouse magic. Moreover, the demon king was relieved of petrochemical magic by Daolon Wong and Torre, and he didn't need mouse magic, but in case of obsessive-compulsive disorder, the demon king needed to lower the spell power.
The source of the power of the zodiac is unknown, and so is the source of the eight demons. The Lord happens to be a dragon, so he just got the magic of the dragon and then snatched the power of the zodiac from other animals. Spells didn't exist originally, only the power of the zodiac, but the Lord got all the power of the zodiac and was turned into a statue by Lopez. The magical power of the zodiac also turned into stone, resulting in twelve spells. The other eight demons have no spells.
Summary:
The power source of the Twelve Spells is the Chinese Zodiac in China, and the main palace is also in China. The Lord is also a hybrid of dragon and west dragon, so the Lord may have gained the power of dragon spells from the beginning. As a magician, the Lord is also interested in the power of his own dragon spells, so he looks for other animals with magical powers and takes all these magical powers for himself with his own magic.
