'It' [I]

After the duel… Xie Qing began to feel drowsy.

"Hm?"

Sitting in the lotus position on his bed, the youth narrowed his eyes. His consciousness seemed foggy, and he felt tired.

"I… feel sleepy? Strange. This is extremely strange…"

The only reason he hadn't fallen asleep was his cultivation level. Therefore, he suspected that this strange phenomenon was artificially induced rather than something physical.

And after observing his surroundings a bit… Xie Qing wrinkled his nose.

"Does this old man want to rest in peace so soon? Does he think I won't kill him?"

Li Su. The main reason for his drowsiness was this annoying old man. Although the old man presented himself as a straightforward warrior who would go directly at the enemy without hesitation…

Xie Qing suspected that he was quite cunning, as evidenced by the duel incident. Therefore, he was on guard.
