In truth, Lin Changqing's realm had already reached perfection many years ago; as long as he wished, he could emit his aura at any time and summon the Heavenly Tribulation.
However, he dared not take such a risk, for his mental state had been unexpectedly damaged in years past!
Thus, even though Lin Changqing was extremely confident about surviving the Thunder Tribulation, for many years he could only hide within his Cave Heaven, restraining his aura and concealing his fate from the heavens.
It was because he had no confidence in passing the Heart Demon Tribulation, and even worried that he might perish because of it.
As Li Zhirui grew and his reputation spread, many came to know that the Purification Principle could effectively restrain Heart Demons!
But the problem was, Lin Changqing did not cultivate the Purification Principle, but the pure Wood Principle; thus, even though he knew of the restraint, there was nothing he could do about it.
