My name is Yan Chenyi. The high school entrance examination has just ended. I planned to have a good sleep, but in the end——
I infiltrated the National Seismological Exploration Bureau and stole an "abnormal signal" that did not belong to this era.
Three hours later, this signal triggered full martial law on the northwest defense line;
Three days later, my account suddenly had one million soft sister coins;
On the fifth day, my name appeared on the wanted list for leaking state secret intelligence.
No one knows that I am actually a time traveler.
There is also a technological system in his mind that can combine old radio stations, discarded steel and batteries into signal capture devices, energy radars, and unmanned defense nodes.
I'm not a spy or a terrorist,
But I know that something is coming to this world—bigger than an earthquake, more terrifying than war.
And I must use a wrench, a chip, and a technological system before the beast comes.
Build my own fortress.
Not to be a hero,
But to survive.
