Eight years later, the fireball technique reached level 999! In the real world, someone finally entered the Marfa Continent and started fighting for resources in the Novice Village!

One is not enough? Ten! Ten is not enough? Hundreds! A hundred is not enough? 999! Have you seen the sky fire? Have you ever seen a shooting star? Have you ever seen a meteor that could destroy the world?
