Gu Shanhai had indeed considered researching the phenomenon, but after hearing the warning from the Maneki-neko, he lost the interest.
One of his strengths was that he listened to advice. No matter what the other person's intention was, there was no need to stir up trouble intentionally. Besides, the other person had said not to research the serum itself, but that didn't mean he couldn't study the finished product.
When the time came, he could simply borrow some samples from He Lingyun, and then he would likely reap even greater benefits.
By the time Gu Shanhai arrived at the dormitory building where He Lingyun was staying, the place was in utter chaos, and He Lingyun himself had passed out. The muscles under the surface of his skin were writhing, and his bones were even shifting out of place.
