Eight years later, he left the village and told Li Guanqi to join the Daxia Sword Sect — while it may not be the richest sect, it was virtuous. Then, he gave Li Guanqi a sword coffin and made him promise 2 things: that he would always carry it on his back, and to only tell people it was an ordinary sword box.Will he be able to uncover the mysteries of his sword coffin? Why was there a spirit trapped inside it? Who exactly was his grandfather?His sister was worked to death, his mother was seriously ill, and his gambling-addicted uncle even set his sights on the money meant for his sister’s funeral. Li Guanqi, wielding a knife, killed the man, until he encountered an old man named Su Xuan. Eight years later, the youth had become a swordbearer. Behind him was not a scabbard, but a sword coffin, the coffin for burying swords! From then on, this youth with ambitions as vast as the skies stepped into the blood-soaked world of cultivation!

The most unexpected weird destiny,
The most intense brain collision,
The cruelest battle of life and death,
The craziest bizarre fantasy,
The most bizarre truth …
It’s the first time, and another ten years!
