With an ordinary person's physical fitness, at most they can sustain fighting for a quarter of an hour before becoming utterly exhausted.
After all, combat is not exercise; even a slight mistake can lead to death. Fighting requires extreme focus and intense use of the body. An average person can barely endure a quarter of an hour, which is the limit, while some well-trained individuals might last longer, but even that endurance is ultimately limited.
In the end, real combat is actually just a matter of an instant. As the blade sweeps past, it's life or death. One must fully unleash all their spirit and will, all their skills and experience, within that single moment to bring forth the power sufficient to kill.
Yet now, the battle in Dengzhou City has lasted for a full two hours.
Every breath is extreme killing intent; every moment is an end and death. If an ordinary master were to step in, even using Evil Qi, they would probably be slain instantly.
