Lin Ye was an ordinary modern man, born with an extraordinary physique and fighting instincts. But the rules of a peaceful world suppressed his talents, and he eventually faded into the crowd. At twenty-eight, he fell off a cliff while saving someone, only to be reborn and transmigrate to the Great Yan Dynasty, where demonic beasts ran rampant and martial arts flourished. He regained the peak body of his sixteen-year-old self and awakened his dormant fighting instincts. Eager to seek the Dao, he traveled to a great sect, but tests revealed that he had no martial arts spiritual root. The orthodox cultivation world shut him out completely, leaving him to retreat to a small mountain village and live in peace. There, he rescued Shen Qingyao, a woman with amnesia. The two grew close and married, and he thought they could spend their lives together. But then a demonic beast disaster suddenly erupted, and Shen Qingyao was recognized as a lost descendant of an ancient clan. The top-tier Chu family abducted her by force. With his village destroyed and his beloved taken, Lin Ye’s dormant fighting spirit, buried for half his life, blazed awake. He fought through the night, slaughtering every invading demonic beast, but his own body was on the verge of collapse. With the orthodox path of cultivation closed to him, Lin Ye made his heart the source of his power and battle the fuel. He took apart the countless cultivation methods of the world and created the Battle Intent Art, a path that relied on no spiritual root, forging a way of battle all his own. He tempers his strength by slaying demons and travels across the land. As he faces a united assault from the orthodox cultivation world, he must also fight through deadly trials before the Chu family sacrifices Shen Qingyao. Though he has no spiritual root, his undying battle intent lets him break through the limits of heaven and earth. Step by step, he reaches the peak of combat prowess, determined to find his lost beloved and make up for every regret from both his past and present lives.
