The Second Tribulation Thunder Summoning Talisman comes from the *Tai Chi Thunder Concealment Book*.
The First Tribulation is Celestial Thunder; the Second Tribulation is Earth Fire.
It's called Celestial Thunder, but it actually contains the Five Yang Thunders, Five Elements Thunder, All Heaven Thunder, Four Directions Thunder, and more.
It's called Earth Fire, but it actually contains Earth Fire, Heart Fire, Samadhi True Fire, and more.
Though named Second Tribulation Thunder Summoning, it is actually a tribulation of Thunder Fire. With Celestial Thunder from above and Earth Fire from below, this so-called tribulation isn't for the caster, but for their opponent!
Overcoming it is no easy feat.
