I Will Return to the Ruins with My Mortal Bones

Shen Yan, a young mortal, went into the mountains to collect medicine to save his sick mother, but accidentally entered the depths of the Black Pine Ridge. That night, the sword illuminated the mountain and the ghost fire burned the forest. Gu Hanzhou, a traitor to the Xuanxiao Sword Sect, and Old Man Gui Deng, the elder of the Yinluo Palace, died together fighting for a forbidden ancient scripture. Shen Yan was supposed to be just a bystander, but he was forced to accept the "Taiji Guixu Jing" that should not belong to a mortal. This sutra can swallow spiritual energy, absorb death energy, and break the shackles of qualifications, but it can also swallow up the cultivator's emotions and memories. When a mortal touches the scriptures, his body will receive the seal of returning to ruins; when a monk forcibly examines it, his spiritual energy will be lost and his flesh and blood will be exhausted. Shen Yan didn't know what the path to immortality was, but he only knew that his mother was still ill and he couldn't die. He collected scriptures and left the village, went to a casual cultivator, hunted monsters for money, bought rough books to open his veins, and struggled to survive among the sect disciples, rogue cultivators, and the pursuers of evil spirits. It was not until many years later that the sects of the world discovered: The mortal boy who they had once regarded as a piece of cake actually used his mortal bones to subdue Tuntian Guixu.
