Two months later.

I can't remember how many times I've come out of the laboratory, but the researchers say we'll succeed soon.

I smiled wearily and contentedly, thinking that being pricked so many times for blood tests wasn't in vain.

Chen Yun also joined the work in a certain laboratory and would come to pick me up and take me back to my room for rest every time.

My parents didn't like the taste of the cafeteria here, so they often cooked meals themselves and had me eat them after "work".

"Mom, I might be busy these days, so you don't have to cook for me." I left my parents' room with some fruits in hand. "After I'm done, I'll come and accompany you."

Mom saw me off, saying, "It's okay, you do what you need to do, don't worry about us."

I smiled and turned back to my own room.

"Chen Yun, my mom washed some fruits. Do you want... what flavor?"

I closed the door and looked around.

Chen Yun sat by the window, rare without any books or materials in front of him, just a glass on the table.

I picked it up and sniffed, mocking him mercilessly, "Oh, what's troubling you? How come you're drinking alone?"

He looked up at me, his eyes somewhat hazy, as if tinged with sadness.

"Yu Miao, I have something to tell you."

I suddenly felt nervous. "Wha-what is it? Are you turning into a zombie?"

"No." He leaned against the wall, took a deep breath, and said, "I'm sorry, but... I don't want to hide it from you anymore."

I sat across from him, unable to read his expression.

In fact, I had a premonition long ago that this person wasn't as simple as he seemed.

But when the puzzle was about to be solved, I suddenly felt scared, even wanting to escape.

After all, whether it's true or not, he has been the only person I can rely on during this time, the one who has helped me survive and provided me with food and shelter. To exaggerate a bit, he is even my only spiritual support in this apocalyptic world. If I were alone, I might give up or go crazy.

Chen Yun finally spoke, "Have you read novels or watched TV dramas?"

"Of course I have."

"What if I told you that we are not from the same world, would you believe me?"

I opened my mouth but didn't know what to say.

"You and I are not from the same time and space. My mission in this world is to find that person with the unique constitution and safely bring them to the refuge center, so that the researchers can use the antibodies to successfully develop a cure and prevent the destruction of the entire world."

"Yu Miao, this is the first time you've met me, but it's the tenth time I've met you."
