The male lead was called 73, and he was an immortal. He had no previous memories. The novel that started with the planet Inferno being destroyed by a single person was very old. This novel might be written by Chen Dong, the author of Planet Purgatory, who is one of my favorites. The background of the story was a planet called Inferno, which had all kinds of terrifying scenes and dangerous creatures. The protagonist of the story was called 73. He was an immortal cultivator who had experienced countless dangers and challenges in his life. At the beginning of the story, 73 was sent to support a practitioner called the Balrog, but the Balrog's power was too strong, causing 73 and his support team to be defeated and the entire planet destroyed. The story was full of ups and downs, with strong sci-fi and fantasy elements. It was a very classic novel.
