Song Yunxiang, the final Star Soul General of humanity, once stood on the front lines against monstrous enemies in a desperate future. But despite all his strength, he carried countless regrets. Back when he was still a teenager, his incomplete soul left him powerless, forcing him to helplessly watch friends, family, and comrades die one after another before his eyes.

Now, fate has granted him a second chance.

Reborn through a mysterious system, Song Yunxiang returns to his school days while retaining sixty years of combat experience, advanced technology, and battlefield knowledge from the future. Armed with memories of humanity’s destruction, he begins preparing long before disaster arrives. From developing powerful mechas to hunting terrifying monsters, he starts rewriting destiny step by step.

In this new life, he refuses to repeat the tragedies of the past. The people he once failed to protect, the opportunities he once lost, and the regrets that haunted him for decades—this time, he will change everything.
