"Huuuu." Exhaling loudly, he collapsed rigidly on top of the bed, his legs screaming in agony.
But he quickly passed mana through his legs, immediately alleviating the painful feeling he had.
"Hmm, having mana really helps a lot..." Hael thought. If he had not been a cultivator, he would have no choice but to wait till the pain left.
[There is something cool that you can even do to prevent feeling sleepy...] The system suddenly said to him as Hael raised an eyebrow.
"What is that!?" Hael asked curiously.
[Other cultivators might be unable to do it, but you can. The ability to slow down or speed up your brain by revolving mana within!] The system said to him as Hael's eyes flashed in shock.
