The immortal dao was boundless, yet it still lay within the Heavenly Dao. Vast and limitless, it was also known as the Great Dao.
Though immortals did not fear calamities, heavenly tribulations were merely the trigger. The greater Great Dao manifested according to the dao body, qi, mind, and spirit of the one crossing the tribulation.
For the tribulation crosser, this was merely a calamity formed by a dao opposite to their own.
For cultivators who forcibly intruded upon a heavenly tribulation, it was equivalent to a higher level of dao contamination.
Realms were nothing more than a form of summary, a classification, not the truth.
Cultivators who had mastered the boundlessness of any one of dao body, qi, mind, or spirit could use infinity against infinity and fear no dao contamination. In theory, they already stood in the same domain as immortals. This was also why those who crossed tribulations were called loose immortals.
Those comparable to a living Great Dao, however, were cultivators above Dao Fruit, at an even higher level.
Thus, only dao contamination on this level could affect immortals.
Yet it only affected an immortal's dao. The Limitless Merit of their body, qi, mind, and spirit remained utterly untouched.
The consequence of having the body bear the Great Dao was merely a temporary slumber of the self, while Dao Nature ruled the body.
However, whether bearing the Great Dao with one's body or interfering with a heavenly tribulation, one could only do so after achieving the Dao of Boundlessness and attaining Dao Fruit.
To cultivators beneath Dao Fruit, both heavenly tribulations and those crossing them existed on another layer—one they could not interfere with and could only observe with their naked eyes. Accordingly, they would not be affected by the heavenly tribulation either.
At that moment,
