These seven thunder spirits are all the highest tier of thunder spirits.
But even among the highest tier, there are differences.
Among the seven thunder spirits, the first and second, namely the Earthpulse Thunder Spirit and the Ziyou Thunder Spirit, are at the same level, both are Qian Grade Thunder Spirits.
Thunder spirits, from worst to best, can be divided into pseudo, false, genuine, Qian, Kun, and Divine six grades.
Among them, the pseudo grade is the worst, the term pseudo clearly indicates that pseudo-grade thunder spirits cannot actually be considered genuine thunder spirits.
The false thunder spirit is slightly stronger but still cannot be considered a genuine thunder spirit; only when it reaches genuine grade can it be considered a genuine thunder spirit.
And among the seven thunder spirits left by the Supreme Thunder Spirit, the worst Earthpulse Thunder Spirit and Ziyou Thunder Spirit are both Qian Grade, belonging to the top of the top in the Minor Thousand Worlds.
