Professor Rupert couldn't bother to ask more questions and immediately stood up, snatching the tablet from the student's hands.
Looking at the selectable difficulty levels photographed on the instrument, Rupert felt his heart was about to leap out of his chest.
"X level, someone actually reached the X level!"
It was understandable that the student had never heard of this level because this level of test didn't originally exist in the device's design, but was whimsically added by Rupert himself.
The original design of the reaction test device did not distribute the levels like this but was the same as the X level test Li Ang had attempted.
From the beginning to the end, there was only one difficulty level, but the speed and firing rate of the bullets would continuously increase with time until reaching the maximum operating power of the machine.
