I'm 200 Years Old. Call Me Grandpa.

Zhou Junyu, a 200-year-old patriarch, failed his tribulation and became a powerless child. He relied on Ye Haitang's medicinal fragrance to survive, called her "mother," and helped her defeat enemies. Returning home, he summoned thunder to restore his senile grandson's mind. He protected Ye Haitang, thwarted plots, regained power through live-streaming, and ultimately punished the wicked, restoring the Zhou family to glory.
