Xu Milu listened very attentively.

"Both male and female sirens can lay eggs, but for one hundred days after the eggs are laid, the sirens parents will collect the purest pearls and put them in the nursery so that the eggs can absorb the energy from the pearls. This way, the children will have strong fish tails after they are born. If there are no pearls or the pearls are not pure enough, the hatched sirens may lose their fish tails and become Tata or sirens that are closer to humans."

Nanako gently hugged the egg in her arms, her face radiating a soft maternal glow:

“The pearls that have recently been produced in Pearl City are not pure enough to meet the survival needs of these children. If this continues, they will become weaker and weaker until they die.”

Xu Milu was slightly surprised. She hadn't expected that such a beautiful and dreamlike creature as a siren would have a degenerated fish tail, and that pearls were actually a necessity for them to incubate their eggs. No wonder pearls were the hard currency here.

"So...you want me to help you collect pearls with higher purity?"

Xu Milu asked tentatively.

Nanako shook her head:

"No, I want Lady Milu to investigate the reason why the purity of the pearls produced in Pearl City has recently decreased. They are now in their mating season, and more and more sirens are choosing to lay eggs. If the cause is not found, more sirens will die."

Xu Milu stroked her chin and pondered for a moment, then suddenly asked, "Ah Hai is a noble siren, doesn't even he know the reason?"

Nanako nodded, looking somewhat sad:

"We have distributed the white pearls in our stock to everyone as much as possible, but there are still some cubs that cannot hatch. If this continues... Pearl City will disappear."

Xu Milu did not readily agree:

"I can't give you an answer right now, but I have a batch of good quality white pearls that I can sell to you. More white pearls will follow, and I hope they can be of some use."

"Really?"

Nanako was pleasantly surprised: "It's mating season now, and most of the sirens in Pearl City choose to lay their eggs at this time. We need far too many pearls. Do you really have a way, Lady Miru?"

"Quantity is not a problem."

Xu Milu was full of confidence.

Just kidding. Putting aside the countless pearl farms on Earth, just look at the four seas in Journey to the West. The pearls produced there could support not only a Pearl City, but also a whole sea monster clan!
