In the Anime Renegade Immortal (仙逆), an old man named Sun Tai (孙泰) arrives at Luoyue Village (落月村) with a gift. Once the mighty elder of the Shiyin Sect (尸阴宗), he now carries death around him like a worn coat. His dao heart shattered during a century of servitude on Donglin Star (东临星).
When Wang Lin (王林) looks at him, he sees a clear number: fifteen years left to live. But ten years later, Sun Tai dies. Not fifteen. What happened to those missing five years? Was Wang Lin wrong? No. The answer lies in a secret that Sun Tai took to his grave—and in the quiet heart of a father who chose not to stop him.
Fifteen Years to Live
Sun Tai’s condition is pitiful but predictable. After a hundred years as a slave in another star system, his will broke. The man who once commanded armies of corpses now struggles to lift a fruit basket. Wang Lin reads his lifespan without effort—fifteen years exactly. No mistake. The number is precise because cultivation worlds run on cold math. Every spell, every injury, every broken promise to oneself subtracts from the final sum. Sun Tai accepts this. He has made peace with his enemies, including Wang Lin himself, who was both the cause and the result of his downfall. In his last days, he asks for nothing but to stay near Wang Lin and his young son, Wang Ping (王平). For a ruined elder, that simple wish feels like freedom.
But fifteen years do not pass. The clock runs fast. Sun Tai fades in ten. Outsiders might blame Wang Lin’s poor calculation, but he is never wrong about lifespans. The truth is more personal. Sun Tai burns through his remaining years not in battle or grief, but in quiet, forbidden acts of teaching. He sees something special in Wang Ping—a natural talent for cultivation. What he does not know is that Wang Ping is not a normal child. He is a blood soul wrapped in a body forged from a single sword energy strike by Lingtian Hou (凌天侯). The boy is not truly alive. Sun Tai, blind with grandfatherly love, never suspects a thing.
The Secret Tuition
Wang Lin warns Sun Tai clearly: do not teach Wang Ping the ways of cultivation. But the old man cannot help himself. At night, when the village sleeps, Sun Tai transforms children’s rhymes into secret techniques. The Three Character Classic becomes a cover for Shiyin Sect’s forbidden methods. A line about filial piety turns into a breathing exercise. A verse about loyalty hides a hand seal. Each small lesson costs Sun Tai a piece of his life. The original novel states this without ambiguity—Sun Tai dies early precisely because he pours his remaining energy into Wang Ping’s hidden education. He does not see it as sacrifice. He sees it as joy.
Critics might say Sun Tai wasted himself. Five years of life for a boy who is not even human? But Sun Tai does not know the boy’s true nature, and even if he did, he might not care. He has lost his sect, his dignity, and his reason to live. Wang Ping gives him back a role: grandfather. The old man teaches because he wants to leave something behind. Not a legacy of power, but a memory of warmth. Every secret lesson is an act of love, and love in the cultivation world is rare enough to be worth any price. Five years is a small fee for feeling necessary again.
A Silent Permission
Wang Lin knows everything. He sees Sun Tai’s late-night whispers. He feels the shift in Wang Ping’s energy. But he says nothing. For anyone else, this would be unthinkable. Wang Ping is Wang Lin’s reverse scale—his most guarded secret and his deepest wound. The boy exists as part of a plan to cleanse resentment from a past life. If Wang Ping learns he is not truly alive, that plan fails. Yet Wang Lin watches Sun Tai teach, and he does not interfere. Why? Because Sun Tai has become important to him. Not as a servant or an ally, but as a person. The old man’s happiness matters.
This silence is the quietest form of gratitude. Sun Tai could have betrayed Wang Lin many times. He did not. He could have clung to revenge. He let it go. Instead, he chose to spend his final years in a tiny village, playing grandfather to a boy made of blood and swords. Wang Lin repays that choice by allowing the old man his illusion. Let Sun Tai believe he is passing down wisdom. Let him feel useful. Let him die with a smile. The five lost years are not a mistake or a tragedy. They are a gift freely given—by Sun Tai to Wang Ping, and by Wang Lin back to Sun Tai. In a story full of cruelty and calculation, that exchange is the rarest thing of all: genuine kindness.
