That day, Zhang Yu had just returned to the dormitory when he saw Le Mulan already waiting there.
Aside from the 0.05 spirit coins earned that day, in the past few days, Le Mulan had successively sought to purchase various samples from Zhang Yu, including blood, sweat, saliva, and others, allowing Zhang Yu to earn another 0.08 spirit coins.
However, as of now, perhaps because the time was too short, the company had yet to find any results from the samples Zhang Yu provided.
The only surprising discovery Le Mulan had made was that Zhang Yu's sweat had become increasingly pure and uncontaminated, not to mention free from medicinal toxins or impurities, and there was not even the slightest peculiar odor anymore, as if it were pure coolant used solely for cooling purposes.
In Le Mulan's heart, she thought to herself that the urine Zhang Yu excreted now might even be cleaner than a mortal's cerebrospinal fluid.
