A Guest in the World of Mortals

I was born on the eve of the third war between the lich and the lich. I originally wanted to marry a fairy, sleep in the heaven, sit and watch the clouds roll and relax, and invite three or five fairy friends to drink tea and brag in my spare time. However, things went against his wishes. The great wheel of fate made him unable to choose. There were thousands of races, and he was caught in the cracks. He could only fight to be the protagonist of heaven for himself and the human race.
