Chapter 551: This koi fish is too awesome! Little Qin is forced to open for business!

Although Ling Xuan was confused about the boss's purpose, she still explained, disinfectant for ornamental fish is made with potassium permanganate. This kind of disinfectant doesn't do any harm to ornamental fish, but it's very effective in eliminating bacteria. Naturally, the quantity has to be controlled. It's not good to use too much at once.

Qin Lin nodded. that's fine. I'll ask the curator to prepare some coins and disinfectant for disinfection. We'll need them later.

Qin Lin already had an idea on how to use the koi fish's skills.

in the future, the aquarium would specially distribute and disinfect the coins, and they could be collected with tickets. moreover, only children's tickets could be collected.

anyway, the koi would not care about the adult throwing a coin.

This fish didn't even leave him, the boss, behind.
