Su Yan could see the regret behind everyone.
When he was six years old, he told the truth and was hanged outside the woodshed and beaten twenty ring feet. From then on he learned to be silent. He saw the face of the dead Taoist monk hidden in the gray mist of his senior sister, saw the sin of poisoning his wife wrapped around the elder's body, and saw the mountain where the head of the retreat was swallowed up by ink-black regret.
He's seen it all. He said nothing. He just wants to live.
But it's so hard to live. On the day he was thrown off the Bone Cliff, he lay among the pile of three thousand bones and touched a ray of remnant soul that he had been waiting for for eight hundred years. When he was about to die, he breathed regret into his body and gained a power that shouldn't exist in this world - regret.
The price was: he forgot the name of the remnant soul and how many years he had been waiting.
This is no accident. Every time you cross a person from then on, you lose the best memory of that person forever. Overcoming Qinghe's guilt, he forgot that she had given him the medicine; overcoming Mo Chenzi's self-blame, he forgot that the old man had taught him how to read; overcoming the blood-slaughter of Immortal Slaughter, he forgot why he came here.
From being a waste of the sect to being the only one who can overcome regrets in the Three Realms, he built the Heavenly Palace in the clouds to house all those abandoned by orthodoxy. He overcame the race's ten thousand-year blood feud, and finally killed himself at the gate of heaven to overcome the imperfections of heaven itself.
And his hair is getting whiter and whiter, his pupils are getting grayer and grayer, and his face is getting more and more like a statue in the temple that has no sorrow or joy.
On the final day, he will forget who he is and why he came here.
But he still squats down when the crying child on the street corner looks up.
