Everyone in the human army was staring blankly. There was a terrifying pressure in everyone's mind, making some of the mages want to throw up, but unable to.
Many of them recognized it... That spell just now had been recorded as an Extraordinary Spell!
The 9th Tier large-scale indiscriminate offensive spell, Thundercloud Storm!
That terrifying spell could only be cast by a Heaven Mage who specialized in thunder and lightning magic. It was said to be a great tool for slaying armies.
Anyone below the Heaven Rank could only die when faced with the Thundercloud Storm.
No one below the Heaven Rank could resist that limitless thundering Extraordinary Power.
No matter how many people there were, as long as they were within the spell's range, they would all suffer the same fate.
This was also why it was said that in front of Heaven Rank powerhouses, numbers had no meaning.
