Zhu Yu had already thought this through: "I started learning martial arts when I was six years old. At first, I just studied by myself using books. When I was eight, I got a formal master."

Lu Yucheng frowned: "Where did the book come from, and where did you find your master?"

"When I was six years old, I went to the palace to attend a banquet and saw Prince An, who was then the fourth prince, reading a book on martial arts. He saw that I liked it and gave the book to me."

“When I was eight years old, Prince An introduced me to his master before he joined the army, and from then on I followed him to learn martial arts.”

"who?"

"Xu Jing".

"Xu Jing? You studied under Xu Jing!" Lu Yucheng was startled. Xu Jing was a famous martial arts fanatic. Many noble families wanted him to teach their children and nephews martial arts, but he refused. He never expected that Xu Jing would take his sister as his disciple.

Unfortunately, Xu Jing passed away three years ago. Everyone thought that Xu Jing's skills had been lost with his death, but they never expected that he had already taken in two apprentices.

"You mean, you and Prince An have known each other for a long time, and you two are actually fellow disciples?"

Zhu Yu felt guilty and dared not look at Lu Yucheng. Xu Jing was indeed his master, but at that time Xu Jing had joined the Northern Army under an assumed name.

At that time, Zhu Si was known for his fearlessness in battle, which naturally caught Xu Jing's eye. Xu Jing took him as his disciple and passed on all his martial arts skills to him.

"Yes, indeed. Didn't you notice, brother, that my martial arts style is quite similar to that of Prince An?"

Lu Yucheng thought about it and realized that it was indeed the case.

However, there were still many things that Lu Yucheng didn't understand, such as why Consort Duan beat her sister for no reason.

Since my sister has such superb martial arts skills, why did her body become so weak after just a few blows?

And most importantly, why did His Highness Prince An write that divorce letter?

He was completely baffled and was about to ask for clarification when his attendant Luo Wang arrived.

"Young Master, everything is ready. Shall we depart now?"

Tomorrow is Naji, which is when the groom asks for the bride's name and, after their birth dates and times are matched, informs the bride's family of the auspicious omens of the marriage and sends gifts. These gifts are a pair of geese, also called the "bestowing goose gift."

Lu Yucheng is going to personally hunt a pair of wild geese today and bring them back to the Marquis of Nanyang's residence.

"Brother, go quickly and bring back a pair of big, beautiful geese for your sister-in-law." Zhu Yu pushed Lu Yucheng towards the door.

Lu Yucheng warned him, "You're not allowed to go anywhere!"

"No, no, I'll stay inside."

Lu Yucheng snorted coldly.

"Brother, why don't we withdraw the guards? With your sister's current skills, there's no need for them to guard her."

The guards on the tree and the roof ridge suffered a massive blow.

Lu Yucheng looked at him: "What do you want to do?"

Zhu Yu blinked his innocent-looking big eyes: "I didn't do anything. Brother, what are you thinking? It'll be dark soon if we don't leave now. If we don't bring back a pair of the best geese, be careful your sister-in-law won't let you into the house!"

Lu Yucheng glared at Zhu Yu and went out with Luo Wang.

With the guards gone, Lu Xiaoyun searched the backyard of the Duke of Zhenguo's mansion even more thoroughly.

She and Zhu Yu now possess the same martial arts skills that Zhu Yu used to have. Even if the secret guards hadn't been withdrawn, with her current martial arts skills, they would be practically useless.

Both of them had already tasted the sweetness and then developed a craving for more.

What Lu Yucheng didn't know was that although he had brought his sister back, he hadn't missed a single day of their shameless nights together.

Zhu Yu even suspected that she might have been reading a lot of little notebooks in modern times, otherwise, where would she have gotten all those strange and unusual ideas?

She always knew exactly how to control the situation, and only after he was on the verge of collapse and begged her several times would she give in to him.

Once they've been given the gift, they completely let loose and won't stop until they've done it a few times.

He suffered greatly, having to beg her both before and after, until he finally gave up, his tears flowing freely.

Afterwards, Zhu Yu took out a small notebook and wrote down all the details for Lu Xiaoyun. Looking at the numbers on the jade bracelet, Zhu Yu chuckled wickedly. "Just you wait, Lu Xiaoyun, when I switch back into my male form!"

I'll get it all back for you, one by one!

No, we need to charge interest before we stop.

Lu Xiaoyun didn't care. Anyway, she was a man now, and she thoroughly embraced the principle of living for the moment.

Zhu Yu even suspected that Lu Xiaoyun had been eating some kind of super nourishing soup at the Prince An's mansion every day.

Don't let the money in Prince An's mansion be squandered.

Despite grumbling, I didn't miss a single expense, but the feeling was definitely getting better and better.

Occasionally, when Lu Xiaoyun was tied up with something and couldn't come, he would stand by the window and crane his neck to look.

Fortunately, Tongjia Courtyard had its own small kitchen. Ever since the first night they discovered that Prince An had climbed over the wall to sleep with their young lady, Qi Yu and Li Feng had been quietly preparing water every night, then closing their ears, shutting the door, and going to sleep.

Although the two were fighting fiercely on the bed, they didn't make too much noise.

After all, when Zhu Yu felt it was not working, he would just bite Lu Xiaoyun.

Lu Xiaoyun could only groan a few times at most.

Zhu Yu often slept until late morning. When Lu Yucheng asked Qi Yu and Li Feng about it, they both said that their young lady was used to practicing martial arts at night and often practiced until midnight.

Lu Yucheng had no suspicions.

...

Lu Yuyan and Ruoling, along with their group, rode horses at full speed and arrived in Mu City three days later.

The epidemic in Mu City is getting more and more serious. Almost every family has lost someone. Physician Jiang, along with a group of imperial physicians and doctors from Mu City, are taking care of the patients day and night.

Before entering the city, Lu Yuyan personally put a homemade mask, which had been fumigated with mugwort, on Ruoling.

Lu Yuyan was a head taller than her. Princess Ruoling looked up at him with her big, bright eyes and a smile.

After putting on his mask, Lu Yuyan placed his hands on her shoulders and said earnestly, "Princess Ruoling, once we enter the city, you must obey my orders, otherwise..."

Ruoling grabbed Lu Yuyan's hand: "I know! Otherwise, just send me back to Shengjing City. I'm tired of hearing about it."

With his hand being held by a soft little hand, Lu Yuyan felt his palms sweating.

But he still sighed earnestly and helplessly, "Princess Ruoling, please don't take my words lightly. If something happens to you, I won't be able to explain to the Emperor and the Empress Dowager, let alone to your two good brothers!"

"Okay, okay, I'll do whatever you say. But you have to promise me you won't call me princess. From today onwards, call me Ruoling, okay?"

Lu Yuyan scoffed, "Heh, I'm not your brother, how can you call me that so casually?"

Ruoling looked into his eyes and said softly, "Don't call me like you would a brother, just call me Ruoling, okay?"

Lu Yuyan felt her throat was a little dry, touched her nose, and muttered softly, "Well, okay then."

Zhu Chen had just contracted the disease, but his condition was not very dangerous. In addition, the newly developed prescription had some effect, so his condition seemed to be okay.

However, Zhu Chen himself was quite frightened.

Zhu Chen was confined to one courtyard, while everyone else except for one servant was gathered in another courtyard for observation.
