The Witcher: Wielder of the Twelve Talismans

After dying under mysterious circumstances, he transmigrates into the world of The Witcher and is reborn. Heaven has given him a second chance at life, but a twist of fate involving the Law of Surprise leads him to become a witcher. He thought he could reach the pinnacle of life through masterful swordsmanship, just like the White Wolf, only to discover that the real world is nowhere near as idyllic as the game. Even with the power of the Twelve Talismans from his original world, every step remains a struggle. All he can do is keep growing stronger, if only to see tomorrow's sun...

(This story respects the original novels. If you spot any inaccuracies, please point them out. The protagonist will not be subjected to excessive suffering, but this is not a wish-fulfillment story. The Talismans are not powerful early on and have undergone some modifications; only later will they demonstrate their rightful power.)
