The second trial of the Great Empress mystic realm was not only a test of one's strength, but it was also a test of one's mental demons.
A warrior's martial life could be as long as a thousand years or even a hundred thousand years. Countless numbers of things could happen during this period. And they would tend to form mental demons of all sizes.
Even a venerable monk would have a mental demon. For example, in the past, the 18 Emperor Arhats from the Daming Temple that had prevailed for a long time in the Tian Yuan world had mental demons as well.
A few disciples survived the destruction of the Daming Temple and the siege of countless Buddhist followers were. However, due to the bloody massacre, they also had mental demons deeply implanted.
The higher a warrior's cultivation level was, the stronger his mental demons were. The more obsessive and persistent the warrior was, the more stubborn the mental demons would be.
