Even if it's a Demon Seal, it's worth a look.
The cultivation of the Demonic Dao does not mean that all Dharma Seals are sinister. If one doesn't cultivate Heaven-Slaying Life-Seizing Seal but only refines Heaven-Ascending Seal of Borrowed Life, it becomes a profound mysterious technique that exhausts longevity, seeking only the final moment's brilliance.
Three years as a Golden Core can accomplish many things.
The only pity is that the Heaven-Ascending Seal of Borrowed Life has limitations. If one is nearing the end of life with only a few years left, the exchanged body won't be exceptional.
To use this method to pass the Celestial Tribulation, at least three hundred years of longevity is required!
As for the Thousand Demon Palm Seal and Four Demons Escape Seal obtained by the Demon Cultivator from the Secret Realm, they all require the souls of living beings to cultivate Demon Techniques, which Gu Yuan won't touch.
