Dragon Ball: Candidate for God of Destruction

[Fan fiction] [System (minor)] [Slow burn] I'm a new author, and this is my first novel. Please let me know if you spot any problems, and bear with me. Sun Zhe was an ordinary young man who suddenly transmigrated to the perilous world of Dragon Ball. Fortunately, he bound himself to a System and, with its help, successfully fused with the bloodline of the legendary Super Saiyan. When surging power awakened within him, Sun Zhe was convinced he was about to embark on the path to becoming strong and turning the world upside down. But one mishap followed another. An unknown black energy quietly latched onto him. This energy was incredibly strange, as if it came from the dark depths of the universe. Once it touched him, it began to mercilessly devour his body and consciousness. Though Sun Zhe had the potential of a Super Saiyan, the black energy tormented him relentlessly. Every attempt to control his power felt like a tug-of-war with the darkness. One wrong move, and he could be swallowed by it completely. In the Dragon Ball world, powerful enemies lurked everywhere: Frieza's brutal rule, the terrifying threat of the Androids, the unknown danger of Majin Buu... Sun Zhe had to face these powerful foes while also battling the black energy inside him.
