Yun Qingzhi fell into a deep sleep for many years after failing to survive his tribulation. When he opened his eyes again, he found himself in a ruined body with its meridians and bones utterly crippled, and a "System" by his side.
The System told him that the original owner of this body had been an Immortal Lord, poisoned and ambushed by his sect, stripped of his cultivation and immortal bones, and intended to be imprisoned as a shared cultivation furnace for the sect members.
Today happened to be the first night. Cold iron pierced his shoulder blades, his bloodstained clothes served as a wedding robe, and he was made to wait for the sect members to "favor" him.
System: Host, as long as you follow the plot and let them abuse you dozens of times, then endure the humiliation and take your own life, these leaders of the immortal sects will go gray overnight for you, their eyes bloodshot as they kneel and beg you to return...
Before it could finish, it watched its Host snap the cold iron chains piercing his chest with his bare hands, then calmly cut away the rotting flesh.
Yun Qingzhi: It's just a minor injury. I'll eat a couple of green herbs and be fine.
After breaking free of his shackles and escaping to the mortal world, the System saw its Host pick up a little snow ferret: tiny, fluffy, palm-sized, and so adorable it even chewed on its own tail for fun.
Yun Qingzhi held up the squealing little snow ferret and studied it for a long while. "It looks like my junior brother."
System: "...May I ask, your junior brother..."
Yun Qingzhi: "He's dead."
As soon as the words left his mouth, the little snow ferret flopped into his arms and played dead.
Later, the leaders of the immortal path tracked him down, intent on dragging him back to their sect.
System: That's the Immortal Lord Zhanlian! He once wielded the Immortal-Slaying Sword and split open the Gate of Heaven with a single strike!
Yun Qingzhi: What a dull sword. What a useless man.
System: That's the Venerable Zhen'e! He once slaughtered three thousand demons in a single day, their corpses filling the entire demon realm!
Yun Qingzhi: The whole demon realm had only three thousand useless fools?
Only later did those leaders of the immortal sects learn that the person standing before them was the foremost Immortal Lord of ten thousand years ago, the progenitor of all techniques. With his own power, he had subdued the Heavenly Dao and wiped out all evil, killing every demon in the world and bringing peace to the mortal realm for thirty thousand years.
And that terrifying snow ferret by his side looked exactly like the last demon in the legends, said to possess the power to destroy heaven and earth, and to have shared a doomed romance with the Immortal Lord...
Yun Qingzhi calmly tucked the round little snow ferret into his arms and said, "This one isn't. It's my cat."
Shi Wu: "...Awooo."
