Making you a son-in-law is not about making you conquer the world.

"The work efficiency is still pretty good!" Lin Ping said with satisfaction as he looked at the wooden floor that had been put back in place, with only a copper pipe added underneath.

Clearly, he wanted to create a real underfloor heating system, using hot water in copper pipes to heat the entire house, rather than the previous fireplace.

Compared with previous heating methods, underfloor heating has the following advantages.

First, the heater was moved outside the door, which reduced the risk of poisoning, and this was the most important thing.

Secondly, because the copper pipes are evenly laid under the floor, the heating is more uniform, and the room is warmer.

"Hmph, even if you were a stone, you'd be warmed up by Master Ping's tricks," Lin Ping said confidently.

Indeed, she should have such confidence. What girls fear most is the cold of winter. Lin Ping solved this problem at its root, so how could Meng Qingge not be moved?

Besides, he's handsome, so being touched by him can easily turn into liking him.

As darkness approached, Lin Ping felt that having only underfloor heating wasn't enough, so he set about making a hot water bottle.

In nature, water has the highest specific heat capacity, and Lin Ping should make good use of it.

As evening fell, Meng Yuanping and his wife returned home in a rage and beat and scolded Meng Qingfan.

Although he is usually a playboy, he wouldn't go so far as to beat someone in the street and cause a scene in the government office, which would be very embarrassing.

They might even be caught by Meng Qingchao and lose their right to compete for the inheritance.

"Kneel down! Don't even think about getting back up until you properly admit your mistake," Meng Yuanping said with exasperation, the leather whip in his hand cracking loudly.

Meng Qingfan felt wronged. He had clearly admitted his mistake, so why did he still have to kneel?

"Mother, save me! Father will beat me to death!" Meng Qingfan said pitifully, genuinely frightened.

Huang Jiayu raised her eyebrows and said angrily, "I might as well beat you to death, just pretend I never had a son like you."

It wasn't because Meng Qingfan had done anything unforgivable, but because he was straying further and further from the path of becoming the heir.

Hearing the pitiful cries, Lin Ping couldn't help but shiver.

As an outsider, what could he say?

Who would have thought that Meng Qingfan would use this method to lure the tiger away from the mountain?

In short, Lin Ping owed him a favor.

Not long after, Rou'er brought Lin Ping dinner, but he had no appetite. He held a hot water bottle filled with hot water in both hands and looked longingly out the door.

"Rou'er, what time does your young lady usually come home?" Lin Ping asked curiously.

He knew that Meng Qingge was often so busy that she forgot to eat and sleep, and he also knew that she might be busy until even later today, but he was still a little worried.

"If Young Master Lin misses Miss, why don't you go find her yourself?" Rou'er covered her mouth, smiling like a flower.

Everyone knew Lin Ping's purpose in coming to the Meng family, and his help to Meng Qingge these past few days further confirmed his affection for her.

"Looking for her? Why would you want to look for her? Isn't it nice to sleep in bed on such a cold day?" Lin Ping hurriedly explained, casually tossing the hot water bottle to Rou'er and deliberately pretending to be indifferent.

"If you feel sorry for her, then take this hot water bottle to her."

The little hands, which were originally cold, immediately felt a warm sensation when they touched the hot water bottle.

"Hmph, a man who has the desire but not the courage," Rou'er said, sticking out her tongue.

She naturally understood Lin Ping's meaning and, not daring to delay for a moment, immediately ran towards the winery.

"It's a dark and windy night, can this girl handle it?" After Rou'er's figure disappeared, Lin Ping felt a little regretful.

How could you let a young girl walk alone at night? Besides, it was snowing outside.

I wanted to chase after her, but then I had to start turning on the heater. Anyway, Rou'er often went looking for Meng Qingge at night, so I didn't need to worry too much.

Lin Ping took some wood from the woodshed, lit it in the heating stove, and as the flames grew, the water temperature in the copper pipes rose steadily, making Meng Qingge's boudoir warm as well.

If he weren't worried about the servants and maids gossiping, he wouldn't mind going to enjoy himself.

"Looks like we need to buy a few open-pit coal mines in Shanxi; this firewood really doesn't burn very well," Lin Ping said, shaking his head helplessly.

The Daye Dynasty did not have the habit of burning coal; they used charcoal for heating, which was not only expensive but also produced short-lived flames.

Thinking about the vast unexploited coal mines in Shanxi, Lin Ping was so excited that he couldn't sleep.

When he's really rich, he'll buy a few hills there and become a coal boss in no time. In the future, he'll use the best carriages to marry off his daughters.

Besides the fact that firewood couldn't be burned easily, Lin Ping also discovered another problem: the wooden doors and windows covered with paper were not airtight and lost heat quickly.

It all comes down to the glass itself; Lin Ping needs to accelerate his glass research.

By the time the water in the copper pipe was hot enough to touch, the temperature in Meng Qingge's boudoir was already suitable for putting on her undergarments.

This is probably Lin Ping's real purpose. If the doors and windows weren't so unreliable, he would have continued to raise the temperature, ideally to the point where clothes couldn't be worn.

Just as Lin Ping was developing a lewd smile, Rou'er hurriedly ran back.

"Oh no! Miss is missing!" Rou'er shouted breathlessly.

The sound immediately drew everyone's attention. Meng Yuanping and his wife were the first to rush out, and even Meng Qingfan, who was kneeling on the ground, was spared punishment.

Lin Ping was clearly slow to react, obviously not yet awake from the dream he had just experienced.

"What exactly happened?" Meng Yuanping asked anxiously.

"Just now, Young Master Lin asked me to deliver a hot water bottle to Miss, but when I got to the wine shop, Miss had already left," Rou'er said hurriedly.

"What if we've gone down the wrong path?" Huang Jiayu dared not consider the worst-case scenario.

"Miss always takes this route," Rou'er explained, looking aggrieved.

She is Meng Qingge's personal maid, so the possibility of her going astray is extremely small.

Moreover, on this snowy night, Meng Qingge wouldn't wander around aimlessly. After finishing her business at the winery, she would definitely return home.

Upon hearing this, everyone panicked; it was indeed a bad omen.

"Fan'er, take some servants and we'll split up to search. Jiayu, wait at home. If Qingge doesn't return within an hour, report to the authorities," Meng Yuanping calmly instructed.

"Rou'er, come with me."

Before anyone could act, a dark shadow swept past, taking Rou'er with it.

At lightning speed, Rou'er was clearly frightened. She pressed her little face against Lin Ping's chest and asked in a childlike voice, "Young Master Lin, where are we going?"

Lin Ping's face was colder than the heavy snow in the sky, and he replied indifferently, "Is this the road Qingge is taking?"

After slowing down a bit, Lin Ping pointed to the due west direction and said.

Rou'er nodded. Afraid of Lin Ping's cold gaze, she still buried her little head in his arms, which felt quite warm.

The heavy snow had left no footprints on the road, which posed a significant challenge to the search operation.

"Jiang Heigou, thank you for teaching me tracking techniques." Lin Ping slowly lowered his body, grabbed a handful of snow with his bare hands, and smelled it.

As expected, nothing was found.
