I'm a Younger Brother, but I Have the Halo of Being the Protagonist.

This is a fusion urban novel world. There are so many protagonists in novels here, including school beauty bodyguards, divine heroes, the Dragon King's son-in-law... Ma Xiaofei traveled through time, but only activated the strongest younger brother system. Just be the younger brother, this damn system always releases some death-seeking missions. [The school beauty drowned and fell unconscious, please ask the host to provide first aid to relieve the boss's worries] [The mother of the reborn person celebrates her birthday alone tonight, so the host is asked to go and fulfill her filial piety on behalf of her elder brother] [The beautiful CEO is drunk, Brother Bing Wang is very busy, please ask the host to send the CEO home] The protagonists gradually became dissatisfied with him and even had murderous intentions. However, they gradually discovered that when they became good friends with Ma Xiaofei, they could easily show off and slap the villain in the face, and the path to the protagonist would be smooth. Once the younger brother's favor with them decreases, everything will go wrong for them. He failed to show off and was slapped in the face. He was mocked by the villain every day but could do nothing about it. Even in the early stage, you will encounter powerful villains in the later stage, and your life safety is not guaranteed. The only protagonist aura in the world seems to be Ma Xiaofei. Only by making friends with him can we share the protagonist aura. So they all started to hug his thigh, trying to please him like crazy. Bodyguard: "Good brother, the eldest lady still needs a personal bodyguard. How about you come?" Shura: "Brother, I give you this engagement contract. You go and marry the daughter of the four major families." Reborn: "Fei, from now on we can discuss our own affairs."
