The letter in his hand was plain and unremarkable. There was only a thin piece of paper in the brown envelope.

The moment the figure received the letter, such a thought flashed across his mind.

The Hereditary Prince had sent him to protect An Lingge, but even after so many days had passed, An Lingge still hadn't blown her whistle.

He thought that An Lingge had forgotten about the Dark Guard. It was only when he heard the whistle that he realized that An Lingge had not forgotten about the Dark Guard.

Now that An Lingge needed to deliver a letter to the Hereditary Prince, it was time for his Dark Guard to come in handy.

"You should know where Hereditary Prince Mu is now, right?" An Lingge's melodious voice came out, allowing her thoughts to run far away from the Dark Guard.

"Your subordinate has been in contact with the person beside master the entire time." Dark Guard did not hide anything and honestly replied.

This meant that he could now deliver the letter to Mu Junhan.

An Lingge relaxed, and the corner of her mouth curved into a faint smile, "After you send this letter over, return to Hereditary Prince Mu's side. I don't need that many people here."

She already had her loyal heart and Bi Zhu by her side.

Dark Guard did not accept, they only said respectfully, "This subordinate will deliver this letter to master as soon as possible. Please rest assured, princess."

As a Dark Guard, he would always do whatever Master told him to do.

Mu Junhan had instructed him to protect An Lingge, so his mission was to protect An Lingge. Unless Mu Junhan told him to go back, he would stay in the darkness to protect An Lingge.

An Lingge suddenly understood, if she could so easily listen to someone else's orders, then she was afraid that her Dark Guard could not be considered as qualified.

She nodded and said goodbye. Then, the figure in front of her disappeared.

Right at this time, the bead curtain made a sound, and Brightheart and Bi Zhu walked in with a small cauldron in their hands.

"Miss, will you place this cauldron in our courtyard?" Bi Zhu blinked. If this cauldron was in their courtyard, who knows what Aunt Li would do.

An Lingge acknowledged her presence. Just as she was about to order the two girls to fry the medicine, she remembered that the recipe was a little complicated. She spun the words in her mouth and swallowed them.

"This recipe is for controlling the plague." Lan Xin had the plague, and all of them had come in contact with Lan Xin just now, so they were easily infected, thus the medicine was indispensable.

A flash of astonishment appeared on Brightheart's face, she didn't know how An Lingge found out about the anti-plague medicine, but she had never doubted An Lingge's words, she only whispered, "Then this servant will go and fry the medicine now."

"Wait." An Lingge called out to her, "This prescription is a little complicated, the two of you, take a look at what I've done."

She walked out of the room with Bi Zhu and Ming Xin hurriedly following behind her with the small furnace in their hands.

Fortunately, when the medicinal herbs were first discovered, Aunt Li and Seventh Prince did not send people to collect them. After that, An Lingge sent someone to move the medicinal herbs out, but he still had some left in his Parasol House.

An Lingge brought the two maids to the storage area where the medicinal herbs were stored. She had to explain in detail about each medicinal herb she took out to them before she could explain to them what they should take note of when concocting the medicinal herbs.

Two hours had passed after the medicinal herbs were fried.

"Send this to father. Tell him it's to prevent and cure the plague and he must drink it." An Lingge poured the fried medicine into a bowl and closed the lid.

When An Yingcheng went into the palace to report the news to the emperor, he estimated that he should be back soon.

Bi Zhu nodded her head, and carefully brought the medicine to An Yingcheng's courtyard.

Ming Xin stayed where she was and started to fry the medicine under An Lingge's guidance.

Her mind was meticulous and astute. At the same time, she raised the fire in both pill furnaces, frying the two pills in an impressive manner.

An Lingge saw that Brightheart had already cut four sets of medicine. Other than the three of them, she also sent someone to deliver a bowl of medicine to the doctor, just in case.

After settling all of these matters, just as An Lingge was about to take a nap, a wife suddenly ran over in a hurry.

"Eldest Miss, happy occasion, happy occasion!"

In the blink of an eye, she had already appeared in front of An Lingge. Although she was still panting, she had a bright smile on her face.

She grinned widely, her smile so wide that even her teeth could not be seen, "Mrs. Mingzhu has sent someone to deliver an invitation to our house, to invite Eldest Miss to be a guest at our house."

Mrs. Mingzhu?

An Lingge suddenly remembered that back then, when she had just been reincarnated, she had temporarily entered the Qing Yun Temple in order to avoid the schemes set up by the Aunt Li. After that, when An Lingyi framed him, it was the Mrs. Mingzhu who stood up for him and fiercely reprimanded An Lingyi.

But the Mrs. Mingzhu was always quiet and did not like to interact with people. Other than burning incense and ceremonial Buddha, she did not go out even once, why would she suddenly invite him to her residence?

"What happened in Mrs. Mingzhu's residence?" An Lingge's eyes flickered as she thought of one possibility.

"The young miss is intelligent, the Mrs. Mingzhu has found her long-lost daughter, and has sent a thread to many families, wanting to introduce her daughter to everyone." The Prince An's Palace had been weakened over the years. If he could get on good terms with the Mrs. Mingzhu, it would be a good thing.

This was indeed the case.

An Lingge thought about the mother and son duo that she had met on the mountain path. Back then, she had hinted at Shen Jiaojiao because of the kindness Shen Jiaojiao had shown him in her previous life. Now that Shen Jiaojiao had indeed been found by the Mrs. Mingzhu, the reunion between mother and daughter, could be considered as her repaying Shen Jiaojiao.

A smile appeared on her face, and her eyes softened a little. "Give me the invitation."

Upon hearing that, the wife passed over an exquisite and golden invitation note. On it was written in small characters, with the invitation letter written on it. Although it was only a few words, the happiness of the Mrs. Mingzhu could be seen from it.

When she recognized Shen Jiaojiao, the reason why she was able to immediately send her lover to the mansion was to let everyone know who Shen Jiaojiao was.

An Lingge's gaze swept across them, her eyes stopped for a moment at the date, and her lips curved into a gentle and sincere smile, "Three days later, I will bring my little sisters to the Mrs. Mingzhu's residence.

Mrs. Mingzhu's invitation wasn't given to An Lingge alone, but was given to all of the women in the Prince An's Palace.

However, this invitation was in her hands and not Aunt Li's. It could be seen that Mrs. Mingzhu still remembered the time at Qing Yun Temple, and did not have any good feelings towards Aunt Li's mother and daughter.

It was just that Mrs. Mingzhu didn't go out for a long time and didn't know that the Old Mistress had already returned.

An Lingge put away the invitation, and her eyes shone brightly.
