[The male protagonist has dual personalities: the main personality is stable + the second personality is crazy] [Daily relaxed and funny + passionate + group favorite. Ps: This book is also called "Who Injured My Junior Brother?" Lu Xiaobai's life creed: Creed 1: A winning rate of only 99.99% Is called a sure chance of winning? Even if it is 100%, there is still the possibility of capsizing! A winning chance of less than 10,000% is risky! Creed 2: If you can fight in a group, never fight alone. If you can fight alone, run away first! Creed 3: The sky is big and the earth is big, a dog's life is the most important. When you are in trouble, it's important to save your life! Creed 4: If you have an opportunity, don't even look at it. After all, opportunity = risk = danger = injury = dog's life is not guaranteed = death! But obviously, it is better to run first every time you encounter an opportunity. Why do those opportunities come to you as if they have grown legs? Lu Xiaobai has always been troubled by this issue... After all, there is no shame in fearing death, and there is no shame in saving life, because in his previous life, he cherished this hard-won new life. But what Lu Xiaobai didn't know was that precisely because of his previous life, he had a second personality in this life, a crazy personality that was completely opposite to his creed. Crazy Pi Lu's life creed: Creed 1: Whatever I like is mine! Creed 2: 0.1% Chance of winning? Isn't that 100%? Creed Three: You are already surrounded by me! Creed 4: Don't hurt me. I've cut myself off, so how can I still spoil you? The entire Xuantian Sect's senior sisters knew that once Lu Xiaobai was injured, he would go crazy and become a completely different person. Xuantian Sect's creed: Never let your junior brother get hurt, otherwise, the consequences will be dangerous!! Who made the junior brother injured?
