Waking up from a deep sleep, Lin Yue found herself having transmigrated into a peasant's new wife, and to make matters more complicated, she was a replacement for a deceased wife. The husband, over a decade older than her, had already lost two former wives. It wasn't so much a marriage; she had been sold to the family by her unscrupulous parents. Her fate was out of her hands. Before her stood one, two, three, four children, like a line of burdens, all gazing at her with blurry and hopeful eyes.

Kieran Silver is a young man who suffered from the deceit of his superiors. His outstanding talents and exceptional prospects to climb to the top of Zenith Online dismayed his superiors.

They invoked their influence to suppress his uprising, ultimately causing his demise. However, rather than perish, Kieran Silver receives a second chance.

A chance to dethrone one of the top 10 guilds, Golden Brigade. An opportunity to create an immortal legacy that would forever live on in players' minds. The ability to reach the zenith in both worlds!

However, as he is reborn, Kieran notices a few things that are different from what he remembered. Could it be that he has gone back in time, or is there an even deeper explanation and a larger power at play?

These questions will be answered, whether forcibly or inadvertently, as Kieran explores a seemingly driving force.

The advent of the Legendary Berserker begins!
