This is probably the story of a salted fish surviving to the end in the world of immortality.
Copywriting 1: Ling Yi has traveled through time. He is neither the protagonist nor the villain, but a passerby. But just time travel, why do you want to travel to the protagonist's younger brother? It's so dangerous, should I follow the protagonist? If you're not that lazy, I should just wait till the end!
Copywriting 2: In this world, I am a passerby. As for why I am here, I have to start from when I was in college... In short, I have traveled through time, but as long as I am passive and slow in my work, the plot will not catch up with me.
Hostess: "What are you doing? You haven't caught up yet. If you are so weak and don't practice, you don't know how you will burp in the future."
Master: "Disciple! Your senior brothers and sisters are either practicing in seclusion or going out to practice. It's not appropriate for you to be here alone."
Male protagonist: "By the way, when I catch up with the little girl in the future, I won't buy one get one free and let me raise this guy too."
Senior brothers and sisters: "Is this guy really my junior brother? Are you sure he didn't come in through the back door?"
A certain system: "Ah! As expected of Boss Ling."
Ling Yi: "Well... It seems that I have been very successful."
Intention: Be a low-key person and do things with a high-profile.
