After a short while, she felt much more energetic than before.
"Wow, I feel so different after taking a pill!" Zi Beiying exclaimed with surprise.
"Gu Ning, where did you get this medicine?" Zi Beiying asked.
"I'm sorry, it's a secret, but there is no need for you to test or study it. It's meaningless. If you need it, you can directly buy it from me. I sold it to Qi Tianlin for a million yuan a pill, but we're friends after all, so you can have 50% off. I suggest that you don't use it to treat common diseases, because its amount is limited. If you want a large amount of it, it's impossible, so you better use it to treat serious diseases, or when someone's life is in danger," Gu Ning said.
