While Liu Hong was staying inside the base, working hard on the time-travel machine and other advanced future technologies, the outside world was descending into chaos due to their arrival.
Every month, people were sent to the future world, but very few returned. On top of that, the remaining manpower had to be used to search this world for undiscovered White Spikes! This task could only be assigned to those who were unable to travel to the future.
In other words, while originally only half the population needed to go to the future to provide support or even die, now, because of the concept proposed by Liu Hong, the remaining half who hadn't gone to the future also had to take action, scouring this world for traces of White Spikes. This meant the entire United States military was mobilized, and for a time, the base actually found itself experiencing a manpower shortage.
