Under Qin Yan's astonished gaze, Qin Wan pulled her over the wall and came to the main courtyard with ease.

There is a happy event at home today, and the servants should have a feast as well. There won't be more than ten or twenty dishes, but there will be eight dishes, and the person on night duty will also have someone send over the food.

But today, not only is there no banquet, but they haven't even had anything to eat. Who wants to go to work on an empty stomach?

Therefore, there were few people everywhere. Even if there were people, they would just gather together and chat. There was no one guarding or patrolling at all.

Qin Wan was already familiar with the terrain. Now that there was no one on patrol, she felt like she was in an empty area, all the way to the main courtyard.

She took Qin Yan over the wall and climbed onto the roof easily.

Qin Yan opened her mouth wide, and only at this moment did she find her voice: "You..."

Qin Wan quickly covered her mouth and said in a low voice, "Don't make any noise earlier or later. Are you talking now because you're afraid no one will know we're here?"

Qin Yan quickly shut her mouth, wanting to see what Qin Wan was doing. Could she still have feelings for Lu Yan? But what had she been doing earlier? Now she was climbing over the wall to watch someone's wedding night?

With doubts, Qin Yan followed Qin Wan and tiptoed to the roof above the bedroom.

Qin Wan had just found a place to stand when she noticed that there seemed to be a figure lying on the other side of the roof. She squinted her eyes to look over, but before she could go forward, the other person also noticed her.

With the help of the dim moonlight, both sides could see each other's appearance clearly.

The first thing the two did was not to fight or run away, but to take out black scarves and cover their faces.

Qin Yan looked at the two of them, covered her face and muttered, "It's too late to cover your face now."

Qin Wan glanced at her and wanted to avoid her, but the best viewing spot was right next to her.

Qin Wan had no choice but to pull Qin Yan over, and the two of them leaned over and climbed down beside Xie Qing.

Xie Qing looked up and down at Qin Wan who was wearing a nightgown. It was amazing that the dress really showed off her figure.

His gaze was too blatant, and Qin Wan glared back, "What are you looking at?"

Xie Qing sneered and said, "Look at the eldest daughter of the Qin family being a thief."

"That's not as good as you, the crown prince, who comes here to steal and steal jade." Qin Wan did not hold back.

Qin Yan had no doubt that if the situation was not right, these two people would fight: "Someone come, shut up!"

The two men then stopped talking, glared at each other, and looked up from the roof into the yard.

Today, not only was there no one guarding the backyard, but there was also no one guarding the yard of the new house. A figure climbed over the wall and came in. He was stunned for a moment when he saw the empty yard, and then went to open the gate.

The Fourth Prince walked in slowly: "No one?"

"No."

The Fourth Prince was surprised. Was Bai Wanyi waiting for him specifically? He quickly walked to the main door and pushed it open.

Qin Wan watched the person enter the house and hurriedly felt around for the tiles nearby. She remembered that a few tiles on the roof were loose, and she had intended to repair them before the rainy season. Now that they were divorced, no one knew that the tiles were loose.

She easily lifted the tile, and a ray of light came out. Qin Wan quickly covered the tile to prevent it from being discovered by the people inside, or if it was discovered by others, it would be bad if someone was sent to check because of the light coming through the roof.

Qin Yan moved closer to Qin Wan and looked down through the gap that was only a thin line left. There was a table set up in the bridal chamber, and Bai Wanyi was eating after changing his clothes.

Bai Wanyi drove out all the maids and old women serving in the room. None of them were satisfied. The old woman in the outer courtyard moved a chair for Qin Wan, and the head maid in his own room poured wine for Qin Wan. They all acted in a disloyal way.

Whenever Bai Wanyi thought about how today's wedding had become a joke, he would stuff food into his mouth furiously, until his cheeks were puffed up.

The Fourth Prince saw this scene as he entered the room. He opened his fan with a swish and said, "Miss Bai, long time no see."

Bai Wanyi looked up and saw that the Fourth Prince had choked, almost choking to death. She hurriedly grabbed the tea and drank it. After finally catching her breath, she hurried out to check and closed the door. "Why are you here?"

"Oh, is this your attitude towards me?" The Fourth Prince sat down at the table and looked Bai Wanyi up and down. This woman had changed, yet seemed to remain the same. "A few years ago, you were very enthusiastic towards me."

Bai Wanyi rolled her eyes at him. After the initial panic, she calmed down again. The one who should be afraid was not herself, but the Fourth Prince. After all, this was a minister's wedding room, and he should not be here.

Bai Wanyi wiped his mouth, returned to the table and sat down, looking at the Fourth Prince with a smile: "Your Highness, we just met you. How can you say it's been a long time? This is the inner house. It's not appropriate for you to trespass into the bridal chamber of a minister, right?"

The Fourth Prince looked at her hypocritical appearance and sneered, "I've been to other places before."

Bai Wanyi's expression changed slightly, and then he smiled again. A few years ago, the Fourth Prince went to the border in disguise, probably because he didn't want to be recognized. Now that he showed up on his own initiative, he might have other purposes.

Bai Wanyi only needed to use her brain, which had watched countless palace dramas, to think about why, and she understood. She was no longer afraid and said softly, "My husband will be back soon. I'm afraid it's not appropriate for the Fourth Prince to be here. Please go back first."

The Fourth Prince leisurely poured himself a glass of wine, holding the glass and smiling, "Don't worry, Marquis Lu won't be able to come over for a while, not to mention..."

He stood up and walked to Bai Wanyi, handed the wine to her mouth and said with a smile: "He drank too much and was unconscious. I just put him next to you. He doesn't know what happened."

Bai Wanyi leaned back but couldn't avoid the Fourth Prince's hand. She knew she couldn't avoid it, so she curled her lips into a smile, and with a charming look in her eyes, she grabbed the Fourth Prince's hand, held the wine glass, drank half a sip herself, turned the glass over, and looked at the Fourth Prince.

The Fourth Prince looked at the faint lip print on the rim of the cup, his throat tightening. This little devil, what a genius! He lowered his head, took the wine cup in his mouth, raised his head and drank it in one gulp.

Bai Wanyi's cheeks flushed, and she looked at the Fourth Prince with watery eyes: "What do you mean?"

The Fourth Prince took out a handkerchief and pinched Bai Wanyi's chin, wiping away the smudged lipstick. His tone and gestures were gentle, but his words were threatening: "I heard that you've been making a big move at the border, and today someone impeached Marquis Lu for embezzling military funds. Tell me, if he knew... would he take the blame for you?"

Bai Wanyi's face turned pale. Even when the prince exposed her confession in public, she didn't panic: "You, what do you want!"

The Fourth Prince said slowly, "Do I need to tell you what I want? As long as you hand over the recipe, I will ensure that nothing happens to you."

Bai Wanyi turned around without hesitation to get the prescription. The Fourth Prince wanted to fight for the throne, so the prescription he wanted must not be something that could make money, but something that could kill him.

The gunpowder and firearms recipes were handed to the Fourth Prince. She looked at him with a pleading look, and the red corners of her eyes were very pitiful: "I'll give them all to you, but you have to make sure I'm fine!"

The Fourth Prince put away the prescription, patted her cheek, and chuckled, "I will naturally keep you safe."

As soon as the Fourth Prince left, Bai Wanyi flipped the table over: "What the hell! Threatening me!"

The drama inside the house ended. Outside, Qin Wan approached Xie Qing and whispered, "Aren't you curious about what the Fourth Prince asked Madam Lu for?"
