"Master, did your strength also improve because of this kind of medicine?" Lu Yaobing asked while blowing her hair.
Song Xiaodong said, "Yes and no. I honed it myself in the past, and later, after obtaining this medicine, it provided a significant boost. In fact, the full efficacy of this medicine hasn't been completely utilized yet, as some ingredients are extremely rare, and I haven't acquired them."
"Moreover, this medicine isn't endlessly effective. Like the two times you took it before, each time the ingredients had major differences. If you take the medicine you first heard about again, it won't have any effect. The medicine you'll take next time will be much stronger in efficacy, which is why I can't determine the extent of its side effects."
"So that's how it is. How long can I keep taking this medicine?" Lu Yaobing asked curiously.
