I recommend the following novels to you ~ 1. "Infinite Fate Rewriting": This doujinshi novel is based on the infinite anime stream, which also includes the dark bullet storyline. The protagonist shuttled back and forth in the fantasy dimension, casting a protective shield, cutting off the lock of fate, experiencing hardships, and not forgetting his original heart. I recommend it to you ~ 2. "Traveling with the Light and Shadow Stone": The protagonist of this novel, Yu Qing, came to a different world. He brought the Light and Shadow Stone to travel to various worlds and became an adventurer. The second volume has a pitch-black bullet as the background. I recommend it to you ~ 3. "Starting from the Darkness to Wipe Out Regrets": The protagonist of this novel, Xing Tian, transmigrated into the dark world of bullets. He had a system that could erase regrets and prevent tragedies from happening. It was a very interesting doujinshi novel. I enjoyed it very much ~ I hope you like my recommendations, and I wish you a happy reading~
