Traveling Through the Wilderness, I Used the Spirit Sacrifice System to Transform Myself into an Immortal

In the barbaric era, the human race was weak and wild beasts were raging. There were ancient relics and pure-blooded creatures who slaughtered cities and destroyed countries at every turn. In order to survive, the human race created the art of spiritual sacrifice and contracted with powerful sacrifice spirits to seek protection. Gu Chen, a modern man, died suddenly while working overtime. He traveled through time and obtained the system of sacrificial spirits. Even the most ordinary sacrificial spirits can become god-level sacrificial spirits under his cultivation. Starting from a small town, he originally wanted to accumulate slowly, but never would he have thought that a Tao-level sacrificial spirit that could rival the True Dragon and Divine Phoenix would actually be by his side and become his dependent sister. The catastrophe of the wilderness has begun. The ancestors who protect the country died in battle and sacrificed their souls. The world is in ruins. Gu Chen cultivates all spirits and rises from the ruins. He holds the sword and fights step by step into the depths of the wilderness... "If I were an immortal, I would make the mountains and rivers in this world beautiful and the country peaceful and the people safe." This novel and its characters are purely fictitious.
