Source of Thunder

Such a fruit is actually not too much to say that it is an artifact. But it has the characteristics of being alive. After obtaining this, the dragon knights also went through a long period of research. After research, they found that the thunder energy contained in this is very domineering, and it should not be possible to take it normally. Otherwise, even the body of the dragon clan can't resist it. But the thunder energy it contains is extremely huge and pure and has super destructive power. It is one of the top few among the Heaven and Earth Treasures.
