Chapter 32 Days Without Day and Night (Please Collect, Please Recommend)
If he wants to contact the outside world and receive radio or shortwave signals, Chen Xin must set up the prepared antenna outside to establish communication with the external environment.
To achieve this, he must at least wait until the wildfires outside are completely extinguished, the temperature has lowered, and only then can Chen Xin open the shelter door and go outside.
However, according to Chen Xin’s estimate, waiting for the external temperature to drop and the wildfires to extinguish might take at least a month.
But if it’s just waiting for the effects caused by the EMP shockwave to dissipate, a few more days should suffice.
The so-called EMP stands for electromagnetic pulse, a sudden, broadband electromagnetic radiation burst. An electromagnetic pulse usually lasts no more than a second.
Electromagnetic pulses are typically triggered by events like nuclear explosions, lightning, solar flares, conduit effects, or electrical sparks. The reason old televisions used to get damaged during thunderstorms was that the lightning-induced EMP burned out the internal components of the TV.
While the duration and impact of an EMP are typically short, this time the EMP was caused by the ionosphere being disturbed by a meteorite, making its duration obviously longer than those caused by nuclear explosions or lightning.
The reason Chen Xin has waited so many days is mainly because, besides the main large meteor, there are also many small meteor fragments and materials ejected into space by the meteor impact.
