After being proven wrong, the madman went into seclusion for a while.

At that moment, a bold idea flashed into Yunzhi's mind.

"Someone come here!" Yunzhi called out, and Rulan immediately ran over and asked, "Miss, what are your orders?"

"Rulan, go and find out where the madman has been these past few days for me."

Whether it's as she suspected, she'll know once she observes the madman's movements.

"Yes, miss."

Ru Lan was quick; in no time, she had uncovered the madman's whereabouts over the past few days. Sure enough, as Yun Zhi had predicted, the madman had been in contact with Qin Er.

It seems someone in the Duke of Qin's mansion will be poisoned again, but we don't know who it will be.

"Alright, take it." Yunzhi returned the file to Rulan and instructed, "The madman should have gotten involved in the Qin State Duke's Mansion matter. Tell our people to be careful. Especially with the eldest young master Qin, I don't want the person I worked so hard to save to die in the end. This kind of thing that ruins our own reputation absolutely cannot happen."

"This servant understands." Rulan nodded, then took the dossier and left.

At the Regent's Palace, Lu Cang of Dongli had been quite busy these past few days, so he hadn't had a chance to visit Yunzhi. However, his attention to Yunzhi hadn't diminished.

So, taking a rare break, he called Mingyi over and asked him what Yunzhi had been busy with lately.

When asked by his master, Mingyi naturally answered without reservation.

"What did you say? She's been going out every night lately?" Dongli Lu Cang frowned, somewhat displeased. Of course, he wasn't unhappy that Yunzhi went out at night, but rather worried about her safety.

Although he knew Yunzhi was skilled in martial arts, medicine, and poison, even tigers have their moments of weakness. How much more so should humans?

Therefore, he was worried that something might happen to her.

"Yes. However, the princess must have gone to detoxify people. Recently, a madman has appeared out of nowhere and likes to poison people. The poison is quite potent, and ordinary doctors can't do anything about it. The princess is kind-hearted and can't bear to see those people die, so she secretly went to detoxify them at night."

After hearing this, Dongli Lu Cang thought for a moment and then instructed, "From now on, you all should protect him secretly."

"Your subordinate understands and will certainly ensure the Princess's safety."

"Okay, go down."

After Mingyi left, Dongli Lucang had no mind to deal with official documents. After thinking for a while, he decided to go see Yunzhi.

Coincidentally, Yunzhi was also free at the time. So she picked up a book, sat down in the recliner, and began to read comfortably.

Just then, a figure suddenly descended from the sky and landed in front of Yunzhi, smiling as he said to her, "Zhizhi, you seem to be enjoying yourself."

Yunzhi put down her book, looked up at the uninvited Dongli Lucang, and said speechlessly, "Doesn't my mansion have a gate? Why do you always like to appear out of nowhere?"

Upon hearing this, Dongli Lu Cang paused for a moment, then smiled and replied, "I just wanted to give you a surprise."

"Surprised? More like frightened."

"Since you put it that way, I'll use the main entrance next time."

"Hmm!" Yunzhi nodded, then asked, "Why are you here? Don't you have official business to attend to?"

"No matter how busy I am, I still have to come and see you." Dongli Lucang said as he sat down opposite Yunzhi and looked her over.

Seeing that she looked noticeably tired, he felt a pang of heartache and said, "Zhizhi, just have your subordinates do whatever you need to do. You don't look well; have you not been getting enough rest?"
