I Contracted and Got Married with a Spirit Beast, and I Was Shocked After I Transformed

Since ancient times, there has been an iron rule in cultivation: Mortals must introduce spiritual energy into their bodies before the age of fourteen to break through the confinement of cultivation. Once the age reaches the limit, the innate spiritual energy will dissipate, the meridians will be completely solidified, the spiritual orifices will be closed, and there will be no chance for human immortality in this life. Monks all over the world practice hard in the seven realms of qi training, foundation building, golden elixir, Yuanying, spirit transformation, emptiness refining, and integration. But young Tunan, nearly fourteen years old, still has no hope of success. In the southwest of Zhongzhou, there is a dangerous place called Shiwandashan. It does not see the sun all year round and is covered with bone-eroding poisonous miasma. And Aiyu Mountain is the most dangerous place for souls to be buried in this desperate situation. That day in the hinterland of Aiyu Mountain, several forces worked together to suppress a Mysterious Coffin Spirit Snake, but Tunan fished in troubled waters in the dark and actually took away the Mysterious Coffin Spirit Snake's natal beast elixir. Little did they know that this beast pill was the beast pill of the World-Destroying God Xiang Liu, and there was even a trace of the remnant soul of the origin in it! The anger in the pill was overwhelming, and the remnant soul instantly backfired on the young man's mind, and his life and death hung on a thread. Fortunately, the spiritual pet that has been with him for many years is actually a vulture with ancient bloodline, and has the ghost fire as a companion divine fire. This fire is one of the ten great ancient divine fires, and it is the most capable of restraining soul ghosts. The spiritual vulture burns the original essence and blood, concludes a blood contract of life and death, and uses a wisp of accompanying divine fire to forcibly suppress Xiang Liu's remaining soul! The divine fire suppressed the remaining souls, and the blood contract sealed the bond. From then on, the down-and-out young man completely cut off the seven realms of humanity and embarked on the endless battle against heaven!
