On My First Day of School, I Revealed the Global Disaster Countdown

From this day on, Night Demons invaded the world. Anyone who broke the rules would be killed.

From then on, the whole world went under curfew.

Su Cheng, a high school senior, awakened his System ahead of time and saw through this global disaster.

Three ironclad rules.

First: Night Demons can never be wiped out. No matter how many you kill, that many will return.

Second: Night Demons appear at seven in the evening and all disappear at seven in the morning.

Third: Learn the Night Demons' killing rules. Each kind has different rules for killing, and you can only survive if you understand them all.

With his Night Demon System, Su Cheng can deduce the killing rules of every Night Demon, and grow stronger by killing them.

Because of him, humanity no longer has to despair, and the order on the brink of collapse has been brought under control.

Because of him, the residential community formed a militia, and brave souls became demon hunters to protect their homes together.

All of humanity received cultivation methods, and a special class for promising students was established at school.

And once again, because of him, the final refuge was set aside for all humanity.

He is Su Shen, a demon hunter who walks through darkness yet brings light to everyone. Remember his name, because he will appear when you call for him.
