But saliva, of such stuff, Zhang Yanhang had truly never partaken; he didn't even fathom why this fellow suddenly thought of him and left him a cup of saliva.
"Although I don't know why he suddenly left me a cup of saliva, if I really drink this, I definitely won't be able to sleep tonight, and this thing coming from a high-level Awakener would suppress drowsiness to an unfathomable degree, far surpassing the likes of Sky Demon Green Crystal Grass in that aspect."
Zhang Yanhang had every reason to suspect that after drinking this, not only would he be unable to sleep tonight, he might even spend several consecutive days and nights in the same sleepless state, which could be rather troublesome.
After all, if this insomniac state were to become routine and lead to a loss of the innate ability to sleep, he would later on be unable to utilize the most efficient deep sleep for energy recovery; instead, he'd have to rely on the less effective method of closed-eye resting.
