All around, the security is using some kind of superconducting laser emitters.
Zhang Feng had seen them in reality; once fired, their activation speed is comparable to Mach 6. Foundation Establishment could not dodge, and would be burned through.
After all, I can achieve Foundation Establishment in one step, but my constitution is too low, and my defense can't keep up.
Moreover, my internal energy is difficult to keep up as well.
However, this world should provide answers.
Because, according to Zhang Feng's hypothesis, if the Emperor Dynasty invented the 'civilization trials' and released the monsters,
then they must have energy conversion devices.
The most direct evidence is that during the trials, there was only a dome-like 'transparent protective barrier,' without any arrangement related to Z1.
This proves that they developed some kind of energy conversion that allows the dome to achieve the effects of Z1.
