Brother Ah Yat and Ah Yuet are destined to face each other in the next battle of the century between the immortals and devils, and only only one is expected to survive.
The century of war between gods and demons is approaching. The immortal world will send the half-immortal son Ritong to fight, and the demon will make the half-immortal wife cherish his flesh and blood, and want to send him to fight on behalf of the demon world. Because the brothers are crippled and out of order, they will defeat the immortal world. After the half-immortal wife gave birth to the child of the demon, Yuetong, he died. The demon wanted to take Yuetong. The half-immortal tried desperately to stop her and was finally lost. Before she died, she locked the demon in the gossip mirror.
