Special Trainee

Once everyone realized that the paralyzing syringe was capable of shutting down the immunity of a person, they all became stunned and stupefied. 

In the current era, almost everyone has their immunity system at the highest protection mark. After all, there were too many harmful substances in space, followed by mutated monsters capable of destroying a human's internal system in a split second. 

Contrary to their shock though, Xu Feng had to clarify something for them. 

"The paralyze syringe is still just a prototype, so the aggressive Trainee immune system will return in 1 minute. The effect only lasts for approximately 2 minutes, but if they have a stronger resistance or if the full liquid wasn't injected, then the duration might be minimized." 

Sure enough, the aggressive Traine's body started to react and began recovering. His limbs, which seemed stiff, had turned normal and were showing signs of him regaining the muscles.
