He Said That He Would Die in Battle, but Why Did He Seal the Wolf as His Subordinate?

During the Jin Dynasty, the emperor and the nobles shared the world, and the people of Li lived in it. Hundreds of schools of thought are spread all over the place, but they only bow to that power. They are destined to be aloof, hereditary, and treat all living beings like rotten dogs... Jiang Yu was originally a soldier in Northern Xinjiang. He and his army fell into the encirclement of the Northern Desert Royal Court. When he was about to die, he was summoned by a girl as a heroic spirit. At this time, spiritual energy has been fully recovered and cultivation resources are sufficient. Jiang Yu travels back and forth between ancient and modern times, and learns of his fate - he will die in this expedition. But he still doesn't believe in this fate, let alone recognize it! Relying on future resources and information, Jiang Yu changed his destiny again and again, going against the will of heaven and reaching the top! … My name is Zhao Xueying, and I contracted a heroic spirit who died in battle. For some unknown reason, he was able to continue to "evolve"! In a profession like the Spirit Summoner, where heroic spirits are the main combat power, how incredible is a heroic spirit that can continuously evolve! This was a great surprise to me, but I never imagined that the "truth" would gradually emerge from the excavation of an ancient ruins, completely overturning my understanding: With the progress of archeology, historians have all noticed that during those years that are rarely recorded in historical records, there was a dark shadow that covered the sky. In that unrecorded place in history, the Great Jin Dynasty and the Northern Desert Royal Court had joined forces to encircle and suppress him, and the inheritance of hundreds of schools of thought was cut off by him alone. Even the stunningly talented empress once performed a dance in front of him... Not only that, he actually ended an era completely. This ultimate villain is actually—my heroic spirit? Talk about how ordinary heroic spirits have been buried for eternity!
