The incomplete time system

[System awakening begins]

"Ugh" Williams grunted with pain. He felt all his cells burning and his head was ringing.

Nevertheless he still gritted his teeth and held the pain without screaming. Only his face was twitching from time to time. Soon he got used to the pain and his face relaxed.

Sweats were running down his body and sizzling sounds were heard from his body.

"How is he in so much pain and he still remains in his calm state?" Yilkiz was puzzled, she chased after Williams when he entered and sat down beside him waiting. After waiting for five hours she left for hunting and came back eighteen hours later, since then she had been sitting here with no work to do.

She was surprised when Williams suddenly groaned in pain and seeing his face twitching in such manner. 

Ding!
