Eight hundred years—a lifetime—had ended once more.
This time, he had no mood to recite poetry.
His spirit was somewhat weary, his heart somewhat heavy.
That was inevitable.
Though the "Eternal Spring and Agelessness" trait could keep his body forever youthful, the aging of the heart was not included.
When the heart gathered dust, though the body remained young, the spirit would decline first. In the end, whether one's heart died and spirit dispersed, or heart demons sprang up in droves and one perished amid the Heavenly Demon Tribulation, both were perfectly normal.
Therefore, cultivation of the heart was crucial. If a Martial Artist in the Spirit Condensation Realm could not achieve perfection of the heart, they could never attain the Grandmaster Realm, much less step into higher realms.
Though Xu Yang's heart had reached perfection, and he had entered the fifth realm—Embracing the Dan and Merging with the Dao, Shattering the Void—eight hundred years of time had still worn away at him, coating his heart with a faint layer of dust and leaving it with a trace of age.
So...
Xu Yang looked at the jade seal in his hand and slowly closed his eyes. In an instant, his mind emptied, as though it had been cleansed and purified. The weight of the years and the exhaustion of time were rapidly washed away, restoring vitality to his heart and returning it to youth.
He Shi Bi!
The Imperial Seal!
This was a rare and precious treasure, capable of cleansing the heart and strengthening the soul.
Even in the Great Tang world, there were very few methods that could directly strengthen the soul and elevate one's cultivation of the heart. One could only improve through focusing on a particular thing and enlightening the Dao; there was no direct cultivation method.
