No one was born invincible beneath heaven, so everyone inevitably had a past and a future. There was always a time of greatest vulnerability: the moment of one's birth. It could even be traced back to the births of one's parents, or further still, to the births of one's ancestors.
Once any one link in that chain broke, the person who came afterward would naturally cease to exist. That was only logical.

Even with Ye Xiwen's mastery of the laws of time, he could not reverse time and slay a Celestial Venerable. He could do so to ordinary gods and Imperial Sovereigns, but there was no need. Ordinary gods and Imperial Sovereigns could be slain with a wave of his hand, so why go to such extravagant lengths?
Thus, this divine ability of the seemingly incomparably powerful laws of time was actually rather useless. Yet the Heavenly Dao possessed such an ability. The Heavenly Dao was the sum of all things, and the timeline was naturally one of them. Reversing it was effortless.
