Chapter 140 - 127 Narrative Cage (End)
"Nothing much, just cooling off."
Li Cheng hung his head down, like a mischievous kindergarten kid, spat a line of saliva onto the ground, and shook his head back and forth, making the saliva swing.
His action, comparable to abstract performance art, filled Gray Rain with question marks. Luckily, Li Cheng immediately recovered and slurped the saliva back in.
"That’s disgusting!" Gray Rain blurted out instinctively.
Li Cheng defended himself righteously: "What’s so disgusting about it? Just as ’Sacred Fire Revelation’ mentions in its fun facts section, many animals including canines and alpacas use saliva evaporation for cooling down."
"Isn’t it better to spit it out..."
"Humans secrete 1 to 1.5 liters of saliva every day, 80% of which is water, and the rest is mucin, glycoproteins, immunoglobulins, free amino acids, and so on. Just by its composition, it’s not much different from some health supplements. Every time you spit, you’re spitting out money."
Li Cheng curled his lips, "Moreover, water is the source of life. If you are unfortunate enough to end up in extreme environments like deserts or oceans, not just saliva, but sweat must be recycled, and even urine must be used when necessary!"
"Why do you get so excited every time we talk about pee, poop, and fart?!" Gray Rain twitched the corner of his eye, feeling somewhat relieved to be a silicon-based life form.
"Now, it is time to face the real Prison Director."
Li Cheng instantly became serious; while Gray Rain grumbled about the ’awkward change of subject,’ he straightened his clothes and strode towards Room No. 3, pulling open the wooden door.
