Awakening System at the Beginning, Acting as a Protector for the Protagonist

After Chen Feng died, he traveled to the world of fantasy novels and became the young master of the Tianming Sect. Why since I traveled through time and became a villain? Ding dong, congratulations to the host for successfully binding the Dao Guard self-rescue system. When Chen Feng was overjoyed after getting the system, he was dreaming of stepping on the protagonist and becoming the best in the world. The system suddenly said coldly: The protagonist will kill you in twenty years. He directly poured cold water on Chen Feng. Chen Feng said: Don't play like this. Is there any way. At this time, the system said: The only way is to gain the protagonist's favorability. As long as the protagonist's favorability reaches 100%, he will become the host's little brother. Chen Feng said: Okay, okay, yes, you can also accept the protagonist as your younger brother. In this case, the problem just now will not be a problem. The system then added: I forgot to tell you, before the favorability reaches 100%, once the protagonist dies, the host will also disappear. Chen Feng: Me. From then on, Chen Feng lived by following the protagonist to gain favorability, and also acted as the protagonist's protector, for fear that the protagonist would die and take him with him.
