Soon, a foul smell emerged from my nose.

I abruptly opened my eyes, and my ears were filled with the annoying sound of squeaking, just like what I heard in the corridor earlier.

I struggled to cover my throbbing head and glanced at my surroundings.

Familiar laboratory equipment, closed windows, the blackboard with the knowledge points the chemistry teacher had just taught during the day, which I hadn't had time to digest yet.

The experimental building!

I remembered, this is the chemistry classroom!

I managed to stand up with great effort but stumbled over something soft on the ground.

Then I saw that there was a girl lying unconscious beside me. She had short hair, bangs, and delicate and childish features. She was the sister who appeared in my dream, the one who jumped off the building after being violated by that principal.

Before I had time to think about it, I was once again choked by the dense white smoke in the classroom.

Several chemical vessels on the desk were burning with unidentified liquids, producing a pungent and choking smoke.

I quickly opened the window and extinguished the flames under the chemical vessels.

At this moment, my phone in my pocket vibrated intensely. I took it out and saw the familiar interface and design, which excited me.

Because it was exactly the same as what I saw in my dream!

However, my head was still throbbing severely, and my memory was fragmented. I could vaguely recall some fragments, but I couldn't distinguish whether they were reality or the dream I just had.

Fortunately, when making an emergency call on the phone, no unlocking verification was required. I glanced at the girl lying beside me, who was breathing shallowly, and noticed the old scars on her body and the prominent nodules on her right leg.

Soon, the ambulance and police cars arrived one after another.

The outside sky was no longer an endless gloomy color but a dark night that made one feel the passage of time.

I looked up at my watch, and it showed 8:05 PM.
