My dad's marriage into my family made me rich, and my fierce yet adorable older sister spoils m

"Ahem... These are just minor tricks, not worth mentioning! As long as we follow the laws of science, even a stubborn rock can be turned into gold."

Professor Lin put his hands behind his back and said in a calm tone.

With a whoosh!

The villagers' eyes were immediately filled with fervent worship when they looked at Lin Hai!

What "Five Black Categories"?!

What kind of stinking intellectual are you?!

This is clearly a living god of wealth who can make barren land grow crops!

Guan Hongying looked at her husband, who was surrounded by everyone like a star, and her eyes reddened with excitement. She stood up straighter than ever before!

Guan Sanya, standing behind the crowd, watched the young man's confident and strategic back as he looked ahead.

At that moment, a ripple, imperceptible even to herself, flickered in her cold and beautiful eyes.

Yesterday's miraculous water, and today's incredible, almost divine, wheat seedlings.

What secrets does their younger brother still hold?

On the gravelly ground above Xigou, the cold wind still blew, but He Youcai's heart was even colder than the winter wind.

Looking at the lush green wheat seedlings covering the ground, which were even growing vigorously.

He Youcai finally realized that he had completely failed this time.

Not only did they fail to control the Guan family, they ended up benefiting them instead!

"Captain He, this agreement is in black and white, and we've even put our fingerprints on it."

Lin Chuan chuckled as he pulled the receipt out of his pocket and waved it in front of He Youcai, his smile seemingly harmless.

"We've already agreed that once the land is plowed and the crops are planted within three days, the harvest from these ten acres over the next five years, after deducting the grain tax, will all go to the Guan family! Captain He is a man of his word, he certainly won't go back on his promise, right?"

As he spoke, Lin Chuan even chuckled twice.

He Youcai was so angry that his face turned ashen. His lips trembled for a long time, and he felt as if he had a breath stuck in his throat, unable to go up or down, feeling extremely suffocated.

In the end, he couldn't even utter a single "no."

After all, if he dared to go back on his word in front of the entire village, he would lose his position as the production team leader.

"Fine! If you can finish it all within three days, then you're really something! But we'll see what happens next!"

With a dark expression, He Youcai abruptly flicked his sleeve and then, along with two of his subordinates, slunk away through the crowd.

The villagers immediately erupted in enthusiastic cheers.

After all, in this era, being able to make the arrogant production team leader suffer was even more satisfying than watching a movie or a grand opera during the Spring Festival.

After this battle, Lin Hai's reputation as an agricultural genius was thoroughly established in the village.

Even when Guan Hongying walks around the village, those gossipy women who used to talk behind her back are now all eager to curry favor with her.

They addressed her as "Sister Guan" and "Professor Lin's family member" so affectionately.

Even intimate gestures made Guan Hongying feel somewhat uncomfortable!

Of course, it's true that it's not something I'm used to.

But in Guan Hongying's heart, she was more beautiful and happier than anyone else!

With the help of the spiritual spring water, the remaining gravelly land was plowed and sown in less than half a day!

With the villagers as witnesses, He Youcai dared not renege on his promise!

More than half a month later, thanks to the day and night work of Master Pang and his apprentices, the two large tile-roofed houses on the east side of the Guan family compound were finally completed!

The house is made of red bricks and green tiles, and the interior is spacious and bright!

The most amazing thing is the firewall and the heated floor kang designed by Lin Chuan!

The day we moved happened to be the first heavy snowfall of the winter!

Snowflakes were falling outside, the temperature had plummeted, and even water was freezing instantly!

But the newly built tile-roofed house was warm and cozy.

As soon as the stove in the kitchen is lit, the heat from behind it circulates through the fire wall into the rooms behind.

Now, not only can you bake pancakes on the heated kang (a traditional heated brick bed), but the air inside the house is also warm and cozy. Even wearing only a single layer of clothing, you won't feel cold at all.

Once things settled down, Lin Chuan focused his attention on the task of helping the girls become literate.

If you're learning to read, simply drawing circles on the ground with a twig is definitely not enough.

To learn knowledge properly, you must have proper textbooks and paper and pen.

However, in those days, buying books required not only money, but also special industrial coupons and cultural goods coupons. These items were not available at the supply and marketing cooperatives, so one could only try their luck on the black market.

"Mother, I want to go to the black market on the outskirts of the county tomorrow to get some books and paper."

At the dinner table, Lin Chuan directly put forward his idea.

"You're alone? Going to the black market?" Guan Hongying's brows furrowed subconsciously, and then her face was filled with worry.

"That place is a mixed bag. I heard that recently there have been people with red armbands patrolling the area, specifically targeting speculators and profiteers. You're just a city kid who doesn't even know the way. What if you get caught? Let your sister take you there."

"I'll take him there."

Guan Sanya, who had been eating silently, suddenly put down her chopsticks, and her cold voice rang out at the table.

"I know that secret passage outside the county town well. I used to take that route to sell mountain products. I'll take him there; nothing will happen."

Hearing this, Guan Hongying couldn't help but nod.

"Yes, your third sister goes to the black market the most. She's the one who gets most of the mountain goods and game. I'll only feel at ease if you go with her tomorrow."

Lin Chuan smiled and glanced at Guan Sanya beside him, then nodded.

"Okay~ But then I'll have to trouble Third Sister."

He was indeed unfamiliar with some of the people here, after all, he had been taken away by his own mother not long after being sent down to the countryside in his previous life, and hadn't had time to learn anything about the place.

Therefore, it would be best if someone could take me there now.

Upon hearing that they were going to the black market in the county town, Guan Siya's eyes lit up instantly, even though she had been struggling with writing.

She slammed the steamed bun she was holding onto the table, then abruptly stood up, raising her hand.

"I want to go too! I haven't been to the county town in over half a year. I heard the department store recently got some new styles of hair ties! Third sister, can you take me with you?"

"Huh? I want to go too!!" Guan Liuya chimed in, waving her little hands excitedly. "I want to go to the county town to buy candied hawthorns and snacks!"

Seeing these two troublemaking brats, before Guan Hongying could even speak, Lin Chuan snapped his fingers and flicked each of them on the forehead.

"Huh?! Lin Chuan, you've got some nerve! You actually dared to flick me?!" Guan Siya covered her forehead and glared at Lin Chuan angrily.

Guan Liuya cried out in pain, "Ouch! Brother Lin Chuan, why are you like this?!"
