Huaijin is an immortal, a serious immortal king. His master is an immortal, his senior sister is an immortal, and his best friend is also an immortal. Of course, immortals are surrounded by immortals. The Emperor of Heaven gave him a palace, but he wandered around the world for a thousand years.
A thousand years. A thousand years is enough to see flowers bloom and fall, enough to see spring and autumn come, enough to see green hair and white snow, enough to see the vicissitudes of the sea, but not enough to see the human world. He can't see enough of the joys and sorrows of the human world, birth, old age, illness and death, the turbulent times, and the end of the world. The real human world is more exciting than what is shown in the playbook. Sometimes he is a swordsman walking around the world, sometimes he is a tea drinker listening to music and drinking tea, and sometimes he is a tourist admiring flowers in spring. He casually rescued the ephemeral life and death, while watching the bloodshed and killing with cold eyes. Everything has its decline and prosperity, but it has nothing to do with him.
