It Doesn't Matter If I'm the Protagonist or Not, I Will Live Until the End

The world went dark without warning, and everyone in the world disappeared. In the eastern world of immortality, Lin Yuan, who has a system, and his younger brother Lin Yuan, who has the ability to enchant, traveled here together. Lin Yuan: Sure enough, I am the protagonist, and I have the golden finger of the system. Just one month after arriving, Lin Yuan felt something was wrong. Why were more and more time travelers coming with their own powers? Are they the protagonists? Five months later, I met a reborn person who also traveled through time and had a mind-reading ability. Is she the protagonist? The time-traveler said that it doesn't matter whether he is the protagonist or not, because two years after the last world, all of us will be destroyed. Until I met the last time traveler, because of her arrival, the plot changed. Mu Mu, who was reborn as a mind reader: Could this be the protagonist? Hug your thighs quickly. Ye Chubai:? ? ? No, I'm sweating profusely. I'm really not the protagonist. You guys with your own powers look more like the protagonist than me. Lin Yuan, who has the golden finger of the system: It doesn't matter whether we are the protagonist or not, because we have to live until the end of this world instance. The next second, the world of cultivating immortals decreed the massacre of outsiders. The senior NPC pointed his sword at Lin Yuan: Are you outsiders? Say, is the master's apprentice Ye Chubai also an outsider? Lin Yuan: Huh? (Sweating profusely) Mu Mu: Huh? There was no such massacre order in the previous life. Ye Chubai: Is it because of the butterfly effect I brought? I just passed through it? Lin Yuan: Brother, (I was also sweating profusely)
