I Play the Role of a Passer-By in the World of Kexue

Hello everyone, let me introduce myself. My name is Xu Xing. I accidentally dressed up as a passerby in the world of Ke Xue - Feng Teng Reiko! ! ! This was a shock. . . But life is still the same, and with the system by my side, I can literally walk sideways! I thought I was an ordinary passerby, but what happened next made me discover that I actually had such an identity... But the happiest thing is that I can meet my favorite characters! ! ! But as a time traveler - of course I have a golden finger. On the first day I traveled through time, I asked the system to grant me Chinese nationality (privilege), and changed my name back to my previous name that afternoon. This was so exciting! Of course, in the Kexue world, I am a freshman at Mihua University. Who knows? You have to learn as soon as you wear it. . . But what I'm most looking forward to is that maybe I can randomly meet a protagonist or a supporting character. Wouldn't it be so cool!
