He heard everything and knew it all.

  My ears suddenly became quiet, and I couldn't hear any sound. I said: "Don't get me wrong, you've been unconscious for a while, shouting and screaming... I'm afraid people outside will hear it, there's no other way to make you shut up."

  As soon as I spoke, I felt stupid, why didn't I use my hands?

  But Wu Yu didn't delve deeper, his whole person seemed like a calm ocean with hidden undercurrents.

  "Uh-huh," he said, "I know."

  I was taken aback.

  What does he know?

  At this time, he was no longer entangled in the problem, looked down at his body and asked: "Where did... gauze and medicine come from?" I pointed to that xiāngzǐ for him to see, and took out the card, saying: "This is what I mentioned last time, the person who left a note for me. Didn't have time to show you, the handwriting of both times is exactly the same." No need to say more, Wu Yu naturally understood the inexplicability of this matter.

  However, Wu's expression suddenly became very strange. He abruptly opened his eyes wide, clenched the paper strip, and his emotions seemed extremely agitated. He even struggled to sit up, I hurriedly supported him, saying: "No way, lie down quickly." He didn't listen, his eyes still staring at the paper strip.

  "I asked: 'Do you recognize this handwriting? Is it right?'"

  His face slowly emerged with a faint smile, and suddenly my waist tightened as he pulled me into his arms. The smell of blood and wound medicine filled my nostrils. Then the back of my head felt warm, it was him gently kissing my temple, and his lips pressed there without letting go. He said: "Jiao Jiao, we're going to be okay now, with this...we'll definitely make it out alive. I promise you, don't worry or fear anymore."

  I raised my eyes to look at him, with a questioning gaze. However, he, whose emotions were fluctuating, obviously didn't plan on explaining anything now. He let go of me: "What else is in the suitcase?"

  I turned over the things in the suitcase and said, "Apart from medicine, there's this thing that looks like a rotten mouse but isn't a mouse. I tried using it, but it doesn't work and there's no signal." He picked up several components and looked at them, revealing a subtle and mysterious smile: "This is not a mouse, it's a satellite phone. Haven't you seen one? When I was in graduate school...I even did a project related to this. But I don't know why it was smashed."

  Satellite phone? I've heard of this thing, but it's the first time I see it. With this, there's no need to rely on the mobile network at all for communication. But why is this here? Did that mysterious person even anticipate that we would encounter a network outage tonight?

  I only feel like I'm standing in front of a deep well, with ripples on the water and an unfathomable depth. I vaguely see the moonlight reflected on the surface of the water, but it's hard to believe. When I look up, I find Wu Yun taking out that pile of things and fiddling with them.

  "What are you doing?"

  "Let's see if we can fix it."

  I was amazed: "Can you fix this?"

  I will fix many things.

  He was also the best science man. I thought about those engineering students from that third-rate university I attended, they could install computer systems. Wu Yu even knew how to repair airplanes, what's so strange about that? So I kept an eye on the movement downstairs while quietly accompanying him. But just a few minutes later, I discovered something was off.

  Although he sat there, looking very focused on the lines and parts, occasionally picking up something from the side shelf. But in just a short while, his face and neck were already covered with sweat. His eyebrows were slightly furrowed, and his face was somewhat pale.
