A short love story with the theme of traveling through time and space

In ancient times, there was a young general whose country was facing a great disaster. He knew that his responsibility was great, so he decided to travel through time and space to find a way to save the country. When he transmigrated to the future, he found himself in a strange world. This world was full of technology and magic, but he felt a little uncomfortable. During his exploration, he met a beautiful witch. The witch told him that the world was facing a disaster because an evil sorcerer had used a power called "dark magic". The witch hoped that the general could help the world get rid of the influence of dark magic and save this strange world. The general was deeply attracted by the witch's kindness and courage and decided to help the witch fulfill her wish. With the help of the general, the witches successfully used a power called "light magic" to expel dark magic from this world. The general and the witch worked together to resist the attack of dark magic and finally succeeded in saving the world. Their love story thus began.
