On the day of the successful experiment, the researchers invited me to celebrate.

I calculated that there should still be some time left until the 100-day deadline.

Chen Yun should be going back.

A waxing crescent moon hung in the sky, and I started to wonder if there was also the same moon in another world.

After dinner, I took a walk with my parents and suddenly felt that this kind of life was also good.

Everything will be fine.

The experiment was over, and I started looking for work at the shelter.

Perhaps to commend my contribution of "donating antibodies to the country," I easily obtained a high-paying job. It was a fairy-tale-like life that I couldn't have imagined before, with regular working hours from nine to five and no overtime.

One day, when I returned to my room, I found a music box on the windowsill.

I was about to question the staff if some mischievous child had entered my room and left the toy here, but when I lowered my head, I saw a card placed under the music box.

It contained a strange sentence.

"Time will hear the wishes of lovers, lies will be washed away, disasters will depart, what is lost will be regained, and lovers will no longer part ways."

【Extra: Yearning for Beauty】

Chen Yun was probably the only one who, despite completing the mission at all costs, still hesitated to go back.

He was eventually forcibly sent back, filled with melancholy and devoid of the satisfaction of saving the world after completing the mission.

He only brought back one thing—a marriage certificate.

It was during the ninth attempt, when the mission failed, that he just wanted to find a place to comfortably lie down for a hundred days and start over. Yu Miao ended up in the same city as him, and in order to move into the shelter, the two of them went to the Civil Affairs Bureau and printed a marriage certificate for themselves.

But they didn't expect that the playacting would turn into reality, and the next time the mission came, he actually fell in love with her.

Even though it was their tenth encounter, this girl had an enchanting beauty in his eyes.

He didn't know why, but logically speaking, he couldn't take anything with him after the last mission.

However, this marriage certificate had been with him all along.

Yu Miao was truly naive. How could a fake marriage certificate fool the system of the shelter?

He knew that he had utilized everything to the extreme.

And precisely because of that, she could no longer accept him.

Being with someone who plans everything step by step would definitely be lacking in security.

He understood that she couldn't accept it.

She was willing to save people; it was her own choice to be great. Demanding that she must save people would be moral coercion.

And to go to such lengths to make her save people...

The more Chen Yun thought about it, the more he felt despicable.

At times, he felt that he couldn't blame himself too harshly, but at other times, he felt that he had committed an unforgivable betrayal of Yu Miao's trust.

After confessing to her, Chen Yun didn't dare to appear in front of her again to avoid hurting her.

He sat in another laboratory, watching Yu Miao willingly participate in the final experiment. He really wanted to care for her or brainstorm ideas to make soup for her to nourish her body, just like he had done several times before.

But he forcefully suppressed his impulses.

When the drug was successfully developed, he listened to the cheers in the laboratory and suddenly felt sad.

It was a sadness unlike any other time.

He couldn't delay the experiment any longer; letting life slip away in despair would be a sin.

Countless times, he had entertained selfish thoughts. At the very least, ensuring Yu Miao's safety would be enough. What if they didn't become the saviors?

But those were just fleeting moments, only lasting for a few moments after seeing her weak and pale appearance.

Perhaps in this world, it's impossible to have it all. Chen Yun thought this way, and a few lines of ancient text inexplicably appeared in his mind.

"With a cassiabranch and a peony flower, the world can be unified."

He had never understood this phrase before, but now he seemed to have a faint understanding.

It was as if he could hear the sound of a music box, playing a familiar tune.

Chen Yun took a deep breath and turned to leave the laboratory.

He knew that he had to let go.

Perhaps one day, when the world was at peace and he had fulfilled his mission, he would go find her again.

But for now, he had to say goodbye.

Chen Yun's figure gradually disappeared into the darkness, leaving behind only the sound of the music box echoing in the empty laboratory.
