The Test of Conscience.
This was the tribulation that all Cultivators of the Unification Realm had to face when breaking through to become a Tribulation Crossing Loose Immortal.
For some Cultivators, this tribulation was incredibly easy.
But for Milton Cheney, the Test of Conscience was the one he had to pay the most attention to.
As time slowly passed, atop the nine-story tower where the thunder had entirely dissipated, only Milton Cheney sat cross-legged on the ground alone.
His eyes were tightly closed, his brow slightly furrowed.
No one knew the perilous tribulation he was experiencing at that moment.
One day, two days, three days.
One year, two years, three years.
Ten years, a hundred years, in the blink of an eye, three hundred years had passed.
No matter how tumultuous the Cultivation Realm might be now, the area around the nine-story tower remained an unspoken Forbidden Area.
