My Enemy Took Away My Body and I Went to Find a Girlfriend?

He is born with a sword of chaos, and his swordsmanship is unique in the ages. Fighting across ranks is like eating. He is decisive in killing and defending his shortcomings. He has the secret technique of seizing the star soul left by his ancestors in his body (which he did not know in the early stage). He is the only destiny killer star prophesied by Star Lord Kueyue'er that can cut off his origin. He is a brainless writer who overwhelms powerful enemies from all walks of life. The supreme star lord in the outer sky, has lived for one hundred thousand star years, controls the origin of the twelve star paths, and can tear down the world's barriers and come across borders. He predicts that he will die under the Tianya Fei Sword in hundreds of millions of years, and specially travels across borders to kill the Destiny Killing Star. He has a cold and unfeeling personality, and regards all living beings in the lower world as dust. Each of his twelve star gods masters a kind of star-destroying magic. Humans practice swordsmanship, aliens control elemental magic, and the laws of extraterrestrial power dominate the local roads. Jianghu sects, ancient dynasties, and the secret realm of demons are three pillars. The Tiangui Chamber of Commerce spans the entire Tianyuan Star Realm and monopolizes mineral veins, magic weapons, magic books, and interstellar teleportation arrays. On the surface, it is a neutral business alliance. It secretly hoards millions of dead soldiers, ancient forbidden weapons, and lost swordsmanship. It hides trump cards that can shake the world. It is only in the middle of the plot that its full power is revealed.
