Tan Jiao also bent down towards the underground river, scooped up water and drank quietly. I gazed at her profile, lost in thought.

  It's been about a day or two since we disembarked, around June 26th or 27th, 2016. On another timeline, I and Tang Jiao have already spent from July 19th to August 2nd together.

  The intersection point of two timelines is getting closer and closer.

  I looked up at the depths of the cave, where a faint glow still reflected, unclear in the distance. Was that secret hidden in this mysterious underground? At the bottom of the collapsed lake?

  The relationship between words and a flock of birds, Chen Ruying's variation, my eyes... still haven't found the answer.

  Furthermore, why is it that only I and Tan Jiao can jump back in time with a half-month cycle. Yan Yuan, Zhu Jiuyi, Chen Ruying, Feng Yan, Wu Miao... all lost their memories before and after the event, until the moment of their death. The expressions of Yan Yuan and Chen Ruying flashed through my mind, their terrified and sudden changes as they looked at me and Tan Jiao, what did they remember?

  Will Tan Jiao and I return to which timeline? My Wu Miao, her fate has not been changed yet, that murderer is still at large. Shen Shiyan is dead... Thinking of this, I heavily pounded the ground beside me with my fist.

  The sound startled Tan Jiao, her body trembled slightly, and she turned to look at me. I said: "Jiao Jiao, come here."

  This familiar endearment probably moved her heart, and she got up to come to my side. I didn't care about the many people behind me, putting my arm around her shoulder and pinching her chin: "Cheer up."

  "Hmm." She still hung her head down. This appearance made me both love and pity her, I leaned in to kiss her.

  I finally felt her body soften, two small hands grasping my collar, looking very gentle and affectionate. I said in a low voice: "You looked like you were lacking love just now."

  These were words she had once said to me, and now they made her laugh, but there was still a hint of sorrow in her eyes.

  I said: "We still have a chance to save Shen Shiyan if we can return to that timeline again."

  "But...," she said, "what if we can't go back? What if we can't change history and save him?"

  She had already buried her face deep in my arms before I could speak, saying: "We've tried so hard, been through so much suffering, and sacrificed so many things... wanting to catch him, but we're not even his match. Not only did we fail to change Wu Miao's fate, but we also lost Shen Shiyan, the man Zhuangyu liked so much... He died... Ah Yu, do you think it's because of our interference that innocent people have been sacrificed? Maybe we can't change anything, and fate is unchangeable..."

  I lifted her face and looked straight into her eyes. Her eyes were red, with stubbornness and grievance in them. This made me feel both sorrowful and pained. I said: "Jiao Jiao, look at me. You're wrong, history can indeed change, and we won't be laboring in vain. The Zhu family was originally supposed to die on the mountain, but we saved them - five lives. As for the Chen family, although only one Tang Lanlan survived, that's still an innocent life. Now, Xu Jingmiao isn't dead, and Ye Xunyi isn't dead either. How much more proof do you need? We can change history; we've always been saving innocent people. Our experiences are absolutely not meaningless."

  Tan Jiao's tears flowed onto my fingertips, making me unbearable in my heart. I lowered my head and pressed her face tightly against mine.
