The Witcher: Grinding Proficiency Starting with the Witcher

Li Wei transmigrated to a world similar to the Western Middle Ages, becoming a Witcher apprentice. He planned to use his Witcher identity to earn gold by killing monsters daily, and if he was lucky, even acquire a minor title and live the life of a lord. However, his potion awakening failed, leaving him with only a month to live. Fortunately, he awakened a class system and attribute panel. What? Mutants can increase life essence? Then kill! [Killing a Water Ghost grants 100% Mutant], restores 5% of life essence, and gains the yellow trait [Underwater Breathing]! ... [Killing a Dragon grants 100% Mutant], restores all life essence, and gains the red trait [True Dragon's Eye]! What if he can't beat a Water Ghost? Then grind proficiency! [Apprentice Physical Skill (Beginner Perfection)], gains the white trait [Body Coordination]! ... [Corona Body Tempering (Legendary Perfection)], gains the rainbow trait [Godhood]! Years later, Li Wei returned to the Witcher's castle with knights as his guards, colorful flags waving and flowers paving the way. The Witcher apprentices were shocked and confused, all looking at the Witcher Master Turka. "Master, aren't Witchers a neutral profession?" Turka glared. "Who said that? Come with me to see the great and supreme King Blackheart!" PS. This book borrows from the Witcher (The Witcher 3) universe, and will later travel to that world using Ciri's abilities.
