That evening, when Yinzhen entered the room, Nan Yi ignored him as usual, throwing two quilts onto the bed, her meaning self-evident. Yinzhen sighed inwardly, not wanting to make a fool of himself.

To win her over, you have to take it slow and patiently.

In the middle of the night, Nan Yi suddenly felt a chill run down her spine, as if danger was imminent. She abruptly opened her eyes, jumped out of bed, and darted to the door.

It had been snowing for a while, and the weather was cold. The snow hadn't melted, and the snow's reflection shone on the door. Through the doors and windows, a faint light shone inside. Nan Yi caught a glimpse of several dark figures flashing past the door.

They sneaked in at midnight; their intentions were clearly malicious.

Nan Yi quietly moved to the bedside where Yinzhen was sleeping. She touched his mouth and reminded him in his ear, "Wake up, someone has sneaked in."

Yinzhen woke up with a start, "Yi'er?"

"Get up quickly, someone has sneaked in," Nan Yi repeated.

Yinzhen's expression changed slightly. He quickly stood up and asked as he dressed, "How many people?"

Nan Yi placed her index finger on his lips. Some martial arts masters could hear even the softest voices, and they could also tell whether the person in the room was asleep or awake by their breathing.

After putting on his clothes, Yinzhen touched her cold hand, silently reached to the side of the bed, took her dress, and draped it over her shoulders.

Nan Yi wrote the word "Thirteen" on Yinzhen's palm. They were safe. He wondered if the Thirteenth Prince in the other bedroom was safe.

She plans to go and take a look.

Yinzhen was worried about her and took her hand, wanting to go together. Nan Yi was also worried about him being alone, so the two opened the door.

Under the faint glow of the snow, the courtyard was empty, with a few bare trees standing by the wall. The night was as cold as ice, and all was silent.

This courtyard was rented temporarily. It was a small courtyard with three main rooms and two side rooms. He and Thirteen occupied the main rooms, while the accompanying guards lived in the side rooms.

The guards were on night watch, but the opponent was more skilled than them, so they were not discovered.

Just then, someone stepped on a dry branch, and with a clear "creak," the sound, like a thunderclap from a clear sky, startled everyone in the courtyard, whether they were asleep or not.

"Who~"

A low shout came from inside the house, and then several figures in the courtyard rushed toward the source of the sound. Thirteen also rushed out of the house.

Yinzhen pulled Nan Yi to the thirteenth brother's side. His martial arts skills were mediocre, while the thirteenth brother was quite skilled, only weaker than the fourteenth brother.

At this moment, he seemed to have forgotten that there was another expert beside him.

"Fourth Brother, are you alright?" Thirteen asked the couple who rushed over.

“You’re too slow to notice, Thirteenth Prince,” Yinzhen said in a deep voice. “As soon as they came in, your Fourth Sister-in-law noticed, but you were still fast asleep.”

If they were truly ruthless, he feared he might have his throat slit in his dreams. Recalling this, Yinzhen broke out in a cold sweat. He never imagined that such a small city like Shicheng was full of hidden talents. Those people must have gone to great lengths for the copper mine.

The danger he felt about the trip to Shicheng increased even further.

Thirteen was not calm either. He hadn't expected that the other side would send such a skilled person to probe their strength. It seemed that they had already alerted the enemy.

In the courtyard, the guards fought fiercely with the three men. Although the guards outnumbered the men, they were clearly no match for them. They gradually lost ground and several of them were killed or wounded.

Nan Yi couldn't bear it and snatched the sword from Thirteen's hand.

Thirteen was slightly taken aback. "Fourth Sister-in-law, what are you going to do?"

She said calmly, "Protect your fourth brother." After saying this, Nan Yi rushed into the fighting circle, kicked one person to the ground, and successfully launched a sneak attack. The person flew out of the circle and was brought down by the guards.

With only two people remaining, the guards were under much less pressure, and with Nan Yi's addition, the battlefield situation instantly reversed.

The remaining two who put up a stubborn fight were quite skilled, and even when they joined forces, they could only manage a draw against Nan Yi. With the help of the guards around them, the two could no longer hold out.

Yinzhen's martial arts skills were mediocre, and he couldn't see the battle in the courtyard very clearly, but the sound of swords clashing made his heart pound with fear that Yi'er would be hurt.

Thirteen, who was protecting Yinzhen, was so surprised that he couldn't close his mouth. "Fourth brother, I must be seeing things. Fourth sister-in-law, where did this freak come from? It's unbelievable. I dare say that even Fourteenth brother wouldn't last four moves against her."

What impressive skill! The moves are expansive and powerful, flowing smoothly and gracefully. Such skill must come from a prestigious martial arts school.

He watched with great interest, praising her repeatedly, and thinking to himself, "Why does Sister Tong's kung fu look so familiar?"

"I married her through proper channels," Yinzhen repeated softly, his tone quite proud.

He knew that Nan Yi was skilled in martial arts, and the guards in the courtyard who were watching over her were just decorations, of little use, and she had repeatedly escaped, which made him very angry.

At the height of his excitement, Thirteen suddenly shouted "Good!" and casually replied to his fourth brother, "You're mistaken, Fourth Brother, it's Na."

In a formal marriage, only the primary wife (嫡福晋) is married; a secondary wife (侧福晋) is a concubine, which can only be referred to as taking a concubine (纳).

Yinzhen pursed his lips, his face darkening as he scolded, "Shut up."

With Nan Yi's help, the two didn't last long before being stabbed by the guards and captured.

She returned the borrowed sword to Thirteen, and casually made a sarcastic remark to him, "You're useless, and your sword is all flashy. What's the use of just looking good? It'll be a struggle to even cut someone down."

Thirteen's sword was heavy, not because the sword itself was heavy, but because of the many gemstone tassels inlaid on it, which made it difficult to use during combat.

These are the things you should avoid most when facing an enemy.

In a battle between masters, victory or defeat often happens in the blink of an eye.

Thirteen was unconvinced and shouted, "This is a precious sword bestowed by Father Emperor, forged by a master craftsman, and is incomparably sharp."

“However, it’s not that bad.” Nan Yi retorted bluntly.

Uh... Thirteen was speechless after Nan Yi's words. She was the one who killed the enemy and captured the spies. Her saying that the sword was not useful was more convincing than her own statement that she had never used the sword.

"Are you hurt?" Yinzhen pulled her in front of him and felt around on her back and arms.

Nan Yi struggled for a moment, "It's okay, just a few petty thieves, they can't hurt me. Let's go inside, it's too cold."

"Hmm." Yinzhen responded, then said to the thirteenth prince behind him, who was feeling discouraged, "I'm leaving it to you. Make them more vigilant."

"I know, Fourth Brother."

Despite being filled with questions and wanting to find out the answers, Thirteen had more pressing matters to attend to.

In the room, Nan kicked off her shoes and crawled under the covers; the assassination attempt hadn't affected her at all.

Only a master like Yuan Qingyi could make her wary.

But how many Yuan Qingyi are there in the world?

Yinzhen sat quietly by the bed. Knowing that she was skilled was one thing, but witnessing her easily take down those three spies was quite another.

He had seen many different sides of her: delicate, domineering, fiery, passionate, indifferent, calm, and so on. Each side made him love her even more.

The scene just now, her amazing move, Thirteen's envious tone, made him feel a sense of pride. This woman was his.

He stared at her retreating figure, lost in thought, his gaze deep and greedy. The person on the bed was fast asleep. A chill crept over him, and Yinzhen gently got up, took the quilt from the couch and placed it on the bed. He then took off his outer robe and lay down beside her.
