After Four Thousand Years of Cultivating Immortality, I Rushed to the Beacon Fire 1937

[System + Time Travel + Patriotism] After being bound to the system for four thousand years, Lin Wan became a tool man under the endless mission. The Overlord contract has been renewed indefinitely, and there is no hope of returning home. She went from refining Qi to the Mahayana stage, and her space was filled with elixirs and magic weapons, and she had peerless skills in her hands. When the contract expires, the system promises to fulfill any of her wishes. Giving up eternal life and glory, Lin Wan only asked: "Send me back to 1937." The system was shocked and warned: there is no spiritual energy there, the cultivation level is completely sealed and turned into a mortal, the materials can only be exchanged three times, and there is a narrow escape in troubled times. Lin Wan had made up her mind. Gunsmoke was everywhere, mountains and rivers were broken, and others only thought she was a weak female college student. No one knows that she has four thousand years of experience in cultivating immortals, possesses secret skills, and holds materials that are enough to turn the tide of the war. I have read the history books of future generations and remember the blood and tears of my family and country. Abandon the path to heaven and rush to the flames of war on earth. With a mortal body, he protects the common people of China and saves thousands of people from suffering.
