Shen Qiqi's face was filled with pride and excitement as she explained, "Look, we've added a layer of earthen insulation here to better lock in the heat and reduce heat loss. This way, not only will it burn longer, but it will also save more firewood!"

Lu Qing looked at her work, his eyes full of admiration and pride. He smiled and patted Shen Qiqi's shoulder, "Wife, you are such a genius!" Shen Qiqi smiled at him playfully, her eyes curved into crescent shapes, and her whole body exuded vitality and confidence.

The two immediately began to implement the new improvement plan, with Lu Qing helping by handing tools and assisting, and they worked in perfect harmony.

After some effort, the new kang was finally renovated.

Shen Qiqi lit the firewood, and soon the new kang gradually heated up.

She gently touched the kang with her hand, feeling the even and lasting heat, and nodded with satisfaction.

"Brother Qing, feel it, is the heat of this kang more evenly distributed now?" Shen Qiqi asked excitedly.

Lu Qing also walked forward, reached out and touched it, a look of surprise on his face, "Yes, it is indeed much better than before!"

Shen Qiqi looked at the smile on Lu Qing's face, and a sense of accomplishment instantly surged in her heart.

She stood up and said proudly, "Now, everyone will have a more comfortable winter!"

When Lu Qing saw Shen Qiqi's results, tenderness flashed in his eyes. He suddenly hugged her in his arms and held her tightly.

He whispered in her ear, "Wife, you are really great. No matter what difficulties you encounter, I will always support you."

Shen Qiqi snuggled in Lu Qing's arms, feeling extremely warm and happy.

She raised her head, looked at Lu Qing's resolute face, and a sweet smile appeared on the corner of her mouth.

At this moment, there was a sound of footsteps outside. Shen Qiqi and Lu Qing raised their heads and saw Mrs. Lu and her eldest uncle's wife, Mrs. Li, standing at the door, their eyes full of curiosity and surprise.

Shen Qiqi's heart moved, and a mysterious smile appeared on the corner of her mouth, "Mom, uncle and sister-in-law, come and see, I have prepared a little surprise for you..." Mrs. Lu and uncle and sister-in-law Li stood at the door, staring at the kang that Shen Qiqi had renovated, with surprise written on their faces.

Shen Qiqi smiled brightly and led them into the house, feeling the even and lasting heat.

"Mom, uncle and aunt, feel the heat of this kang. Is it more evenly distributed than before?" Shen Qiqi asked proudly, with a gleam of victory in her eyes.

Old Mrs. Lu cautiously reached out her hand and touched the kang. She immediately felt a warmth coming from her palm and a satisfied smile appeared on her face. "It's really good. This kang is much more comfortable than before. How did you do that?"

Shen Qiqi explained with a smile: "I added a layer of earthen insulation material inside the kang, which can better lock in the heat and reduce heat loss. This way, not only can it burn longer, but it can also save more firewood."

After hearing this, Mrs. Lu praised her endlessly, "Qiqi, you are such a capable and good daughter-in-law. We are so lucky to have you!" After that, she turned to her eldest uncle's wife, Mrs. Li, and said, "Ms. Li, you should also go back and renovate it quickly. This new heater is really great!"

Although my eldest uncle's wife, Mrs. Li, didn't say anything, she was a little shaken in her heart.

She couldn't help but touch the kang again and nodded, "Okay, I'll go back and try it too."

At this moment, the laughter of children could be heard outside. Apparently, the kangs in other homes had also adopted Shen Qiqi's improved method, and the entire Lu family courtyard was filled with a warm and joyful atmosphere.

Shen Qiqi looked at everyone's satisfied smiles, and the sense of accomplishment in her heart became even stronger.

"Qiqi, now everyone will be more secure during the winter!" Lu Qing said with a smile, his eyes full of pride.

Shen Qiqi snuggled in Lu Qing's arms, enjoying the happiness of this moment.

At this moment, hurried footsteps were suddenly heard outside the door. Looking up, I saw an elder from the village hurriedly walking in with a look of anxiety on his face.

"Qiqi, have you heard? A similar heating method appeared in the next town, but someone started a fire due to improper operation!" Before he finished speaking, the atmosphere in the whole room froze.

Shen Qiqi's heart tightened, and she quickly asked, "What's the situation? Is anyone injured?"

"Fortunately, the injuries are not serious, but the fire department has already intervened to investigate." After the elder finished speaking, he turned and left, leaving Shen Qiqi and her family looking at each other in bewilderment.

Shen Qiqi clenched her fists. "Although her words were brief, they were full of determination.
