The backup energy had been the accumulated power of faith from the Sub-God Pillar over many years.
Normally, using the backup energy temporarily wouldn't cause any issues.
However, the rate at which the power was being consumed didn't slow down; if anything, it was accelerating, which caught the attention of the God Pillar's priests.
At first, the priests thought it might be because a group of people had entered the temple to cultivate. After all, the Holy Realm had been somewhat unstable recently.
It was normal for there to be a sudden surge in the strength of believers.
So, they sent two priests to check the situation.
Upon arriving, the priests discovered that only one person had entered the Temple of Zeus, which immediately seemed off.
What was going on? Only one person entered?
Then why was the energy flow so fast?
