The following day, the clear skies that had lasted for several days suddenly turned into sunshine, followed by continuous rain that lasted for five days. Reports about the river embankments from various regions began to be sent to the palace. The Fourth Prince hadn't even had a few days of rest before he was summoned by Emperor Kangxi again.

Since entering the manor, Yan Yu had been living alone in her empty room. The Fourth Prince had never visited her, and she couldn't go to him herself. In addition, with the flood control efforts underway, the Fourth Prince simply stopped returning to the manor altogether. For several days in a row, he didn't return home, eating and drinking in the palace, and spending his days at the Ministry of Revenue discussing flood prevention and disaster relief with the vice ministers and advisors.

Initially worried that Yan Yu would immediately gain the Fourth Prince's favor after marrying into the family, Wu Shi and others secretly began to mock the two sisters in the main courtyard. Lan Qin continued to live her own little life, seemingly unaffected by whether the Fourth Prince came or not. She only went to the main courtyard to pay her respects a few times and encountered Yan Yu there, but both sides were extremely polite, and no unpleasantness occurred.

That night, Lanqin was about to close her book and go to sleep when she saw that Fourth Master had come through the torrential rain. As soon as he entered the house, she saw that he was wearing a raincoat and a bamboo hat, and he looked like a fisherman.

"Master, you look so funny in this outfit!" Lanqin couldn't help but put down her book, walk up to the Fourth Master who was taking off his "raincoat," twirl around him, and say with a smile.

"If you like it, I'll have someone make you a set another day?" Fourth Master took off his straw hat, revealing his smooth, moon-shaped hair.

"Okay, Master, remember to make one for me too." Lanqin clapped her hands in approval. However, seeing that the Fourth Master looked exhausted, she dared not joke around anymore. She quickly called someone to bring in water to help the Fourth Master wash up, and then obediently rolled into his arms and got into bed.

The two lay on the bed, fully clothed, listening to the patter of rain outside, and neither spoke for a moment.

"Lan'er, I'll be going out again in a few days. Would you like to come with me?" Fourth Master asked, holding the little girl in his arms. The little princess had finished her postpartum confinement, and her face looked a bit fuller than before.

"Is Your Highness going to inspect the river embankment?" Lanqin looked up at Fourth Master's slightly tired eyes.

"Yes, the heavens really like to play tricks on people. A while ago it was so dry, and now it's flooding. They just won't give me a single day of peace!" A flash of annoyance crossed Fourth Master's eyes.

"Where are you going this time, Master?" As soon as Lanqin heard that she was going with Fourth Master to help with flood control, she immediately thought of the Yellow River. This river, which has nurtured countless people along its banks, has also swallowed the lives of tens of thousands of ordinary people. Its name is indispensable in the history of flood control in ancient China.

Sigh, being a prince isn't easy. In the event of any natural or man-made disaster, as Kangxi's representatives, these adult princes had to rush to the scene immediately, just like Lin Mengyao had seen national leaders inspecting disaster areas on TV before. However, in ancient times, disaster relief relied on manpower, with no equipment. Once a natural disaster struck, the area would be flooded in an instant, and there really wasn't enough time to run away.

"I am ordered to inspect the Yellow River channels in Shanxi, Henan and Shandong. Would you like to accompany me?" The Fourth Prince knew that this mission would not be an easy one, but he really did not want to be unable to see Lanqin for several months, so he wanted to take the little princess with him this time.

"I'm willing~~" Lanqin immediately raised her hands and cheered. Although she knew that this was not an easy job to go to Jiangnan, as long as she thought about being able to go out and not having to stay in the inner courtyard every day, and she didn't want to not see the Fourth Master for several months, she immediately agreed without hesitation.

Seeing the little princess's unwavering joy, the Fourth Prince was genuinely pleased. This young woman's sincerity, which was immediately apparent, and her undisguised emotions, truly made him, who had grown up in the masked harem, feel quite different.

"My lord, is it just me this time?" Lanqin nestled back into the Fourth Prince's arms, raising her hand to stroke his chest. She remembered that last time the Fourth Prince had brought both Gengshi and Wangshi. For some reason, Lanqin hoped that this time the Fourth Prince would only bring her. Although the Fourth Prince wasn't hers alone in this mansion, she longed for him to be hers alone outside.

Perhaps, without realizing it, the changes that had taken place in Lanqin's heart were something she herself was unaware of.

"What, do you want me to take only you?" Fourth Master lifted Lanqin's chin and looked tenderly at the little princess in his arms.

"Yes, I wish to go out with Fourth Master and enjoy some time alone together. I don't want any third person to interfere!" This was the first time Lanqin had revealed her desire to have him all to herself in front of Fourth Master.

Looking into the clarity and determination in the little princess's eyes, the Fourth Prince suddenly lowered his head and kissed her, moving down until he stopped between her breasts.

Lanqin was caught off guard by the Fourth Prince's sudden kiss and was flustered. But the Fourth Prince would not allow her to resist and immediately pinned the little princess down.

Because of Lanqin's postpartum period, Fourth Master hadn't touched her for almost a month. Now, he probably couldn't hold back any longer. Like a flood that had been stored up for a long time, his hands ignited a burning passion wherever they touched.

As their passion intensified, Lanqin no longer allowed herself to be caressed by the Fourth Prince. Instead, she took the initiative and climbed onto him. Seeing the little princess sitting naked on his lap, the Fourth Prince squinted at Lanqin, whose face was flushed and whose black hair was disheveled. He was deeply attracted by her beauty at that moment.

This kind of beauty was something he had never seen when he was intimate with any other woman. Most of them had their eyes tightly closed, their expressions pained beneath him as if they were enduring torture, even while flattering him. But the Fourth Master seemed to prefer Lanqin's appearance at this moment. It was a kind of enjoyment and satisfaction of experiencing pleasure, without concealment, without fawning, and without fear.

"Little thing, is it comfortable?" With the rhythm of his hips, the little girl on his body couldn't help but let out moans.

"So comfortable. My lord, I feel so comfortable." Lanqin half-closed her eyes, her expression utterly captivating.

"I want you to stay this comfortable forever~" Lanqin's words ignited the most primal lust within Fourth Master. He straightened up and sat up. The two locked eyes and their limbs intertwined.

Fourth Master reached down to Lanqin's buttocks and lifted her up. Then, he slowly shuffled off the bed, while Lanqin half-hung around his waist, their bodies intertwined.

The two kept changing positions in the bedroom, their lovemaking intense. Lanqin was surprised by the Fourth Master's movements and energy, but she couldn't help but let go. She had been a little afraid of the Fourth Master's passion before, but now, after reaching the peak several times, the most primal desire in Lanqin's heart had been completely aroused.
