After determining the details of the wager, Zhen Yuan and Sima Ling walked to the materials table.
At a glance, Zhen Yuan saw several sets of level seven formation flags and the materials needed for the heavenly inferno formation.
'They are barely enough.' Zhen Yuan thought and subconsciously frowned.
However, he soon regained his composure and chose the materials with the most complete laws.
As it currently was, the heavenly inferno formation was an almost useless array.
However, it wasn't always so.
In ancient times, the heavenly inferno formation was one of the most powerful and popular arrays.
After all, it didn't require many materials to arrange and could operate for a long time because it relied on heaven and earth.
Unfortunately, as time passed, formation masters relied too much on the sun and forgot that the sun was originally a star.
Because of this, the formation degraded from one of the most powerful to an unreliable and weak version.
