The nanny was stunned for a moment, staring at Lan Ziye with her eyes as if she had seen a ghost. She couldn't understand how Lan Ziye knew all this, as she had clearly cut off all ties with the past!

However, it was obvious that Lan Ziye had no intention of saying more to her, and simply had someone drag her away.

After the nanny left, Chu Xixuan looked at Lan Ziye and asked, "Did you just mean that the nanny is a half-demon?"

"There are only two possibilities for someone to have demonic energy on his body. One is that he is a transformed half-demon; the other is that he has been marked by the demon clan. I don't know what the situation is with this wet nurse, but the demon related to her is probably no longer alive!" Lan Ziye said.

Chu Xixuan looked at Lan Ziye in confusion.

Lan Ziye smiled and said, "Do you think if that demon hadn't died, they would have allowed the nanny to roam freely in the Zhu family for so many years?"

Three days later, news finally came from Bluebird. Lan Ziye couldn't wait to get to the pawnshop, and heard Bluebird report, "Young Madam reminded me to start with the connection between Yan Ning, Madam Zhu, and the wet nurse. Indeed, we've found some clues. It turns out that Madam Zhu has been frail since childhood, so the family helped her find a master. That master is called Yuanzhen Taoist!"

"Yuanzhen Taoist? Is that still a popular term in this era?" Lan Ziye raised his eyebrows. Such a title seemed to only exist in the era of three thousand years ago.

"That Taoist Yuanzhen was an alchemist. His alchemy skills were decent, but his heart was crooked. He was a petty thief. Under the guise of saving lives, extending their lifespans, and achieving immortality, he defrauded countless people of their money and defiled countless ordinary girls!" said the Blue Bird. "Having done so many evil things, he naturally had many enemies. Sixteen years ago, Taoist Yuanzhen was killed!"

"Is Taoist Yuanzhen a demon or a human?" Lan Ziye asked impatiently.

"Human race!" replied the blue bird.

"Taoist Yuanzhen not only accepted the eldest lady of the Zhu family as his disciple, but also accepted Yan Ning as his disciple, so Yan Ning and the eldest lady are actually sisters!" said Qingniao.

"We also found out that Taoist Yuanzhen had a daughter. She disappeared after Yuanzhen's death. No one knows where she went, and no one has ever seen her since!" Qingniao said as he took out a photo and handed it to Lan Ziye. "This is a photo of Taoist Yuanzhen attending a meeting. The person standing behind him is his daughter!"

Lan Ziye took the photo and was shocked. "Wet nurse? So Taoist Yuanzhen's daughter is the Zhu family's wet nurse? This wet nurse is really good at hiding her identity!"

"We also found out that sixteen years ago, the eldest son of the Zhu family and the fifth son of the Zhu family both went to see Taoist Yuanzhen, as if they wanted to summon him to the Zhu family, but they were rejected by Taoist Yuanzhen!" Qingniao said again.

"That connects the dots!" Lan Ziye said suddenly. "Madam Zhu, Yan Ning, and the wet nurse are all sisters from the same school. The eldest and fifth sons of the Zhu family have actually known the three sisters for a long time. But what kind of grudges or hatreds are there between them? The fifth son of the Zhu family clearly knew who the wet nurse was, so why did he summon her to the mansion to be his daughter's wet nurse?"

"We don't know yet, because Taoist Yuanzhen himself was a very mysterious existence, and few people knew his private affairs, so the investigation is a bit difficult!" said Qingniao.

"I can't wait!" Lan Ziye said, "I think with this photo we can go and trick that nanny!"
