A nation's industrial development begins with junior engineers.

Chapter 530 What I wish for comes true, brother, are you a lifesaver?

The commotion in the crowd did not affect the "young man" lying on the ground at all.

He methodically took out a balance scale from his large bag, gestured to Old Wang to use a pickaxe to remove the cylinder, and then used a soil-removing knife to scrape away the excess soil at both ends of the cylinder. He then took out a ruler and began to take measurements.

He exhaled a breath of stale air only after the soil sample inside the cylinder had been completely leveled.

The young man waved to Jiang Qiu: "Xiao Qiu, want to try the next job?"

Jiang Qiu's face flushed red as she looked at her grandmother. Only after her grandmother nodded happily did she cheer and toss the marker to Jiang Dong.

"Teacher Sichen! Please tell me if what I'm doing below is correct!"

"It's alright, just be careful. Be careful not to spill the soil sample, and when using a balance, the accuracy must meet the requirement of 0.1g!"

Jiang Qiu took the scraper from the "young man," ignored the mud on the ground, knelt down, and began to dig out soil samples from inside the cylinder.

With Old Wang's help, the "young man" finally stood up.

"Ah, I'm getting old. Bending over for even a short while causes me a lot of pain!"

"Hey, Sister Jiang. Is that young man in the crowd your son?"

Grandma Jiang gently patted Mr. Si Chen's arm, then brushed back the hair that was hanging in front of his eyes: "What do you mean 'old'! You're only a little over 60, you're still a long way from being an old woman!"

"Look at him, it's still the same as it was 30 years ago! He still becomes the most sought-after young man among those 'well-bred ladies'!"

"Hey, it's beneath you to come and help this old woman build a small dam! You're the kind of person who's good at big things!"

"Look at what you're saying, applying what you've learned..."

Jiang Dong, the clever little fellow, first ran to his older brother and snatched a hard candy, stuffing it into his mouth until it was bulging. Then, ignoring his brother's calls, he darted over to the tea area, dragged a bamboo chair over, sat down next to the "young man," and sweetly said:

"Grandpa, please sit down!"

After the "young man" sat down and received the praise, he ran to Jiang Xia's side like a happy little dog.

"Boss! Do you still have that dark, sweet stuff?"

Jiang Xia reached into his pocket and wiped the mud off Jiang Dong's face.

"Have you gone mad again, calling that young man 'Grandpa'?"

Jiang Dong took the chocolate and stuck his tongue out at Jiang Xia: "Hehehe... Boss, you're the silly one. Grandpa Liang is 60 years old, and you're still calling him a young man?"

What?

Looking at the "young man" sitting with his grandmother, Jiang Xia was shocked. No way, a man with a slicked-back hairstyle and wearing black round-framed glasses, you're saying he's 60?

"Wait, what did you call him?"

“Grandpa Liang, some people also call him Teacher Sichen.” Jiang Dong paused, looking at his older brother with some concern.

"Boss, have you gone crazy from working on machines? Isn't Grandpa Sichen your professor at the university you went to? What, you've never met him?"

Jiang Xia sighed and pushed Jiang Dong's face away. "You think this mud-covered person in front of you is that famous scholar?"

Jiang Xia never actually met this famous person at Wudaokou School. Perhaps it was because when Jiang Xia was studying there, this person was out collecting materials for compiling historical records of Chinese architecture...

"How did our little village manage to get this guy to come and build a small dam?"

Watching Jiang Dong run away with the chocolate, Jiang Xia muttered to herself. The five pillars, which she hadn't seen for a long time, surrounded her again in the center.

Upon hearing this, Wu Zhu exclaimed, "Young Master, it was the Ancestor who invited him here!"

"After our ancestors returned, they were worried that Xiaoqinggou would continue to run out of water this year. They wanted to build a dam here to block the melting snow water so that it could help in an emergency."

Sizhu chimed in, "This matter was even discussed at the commune, but the people there said that our ancestors are senile. The amount of labor required to build this dam is not small, and the commune has no money to subsidize it!"

"Our ancestors scolded them for being short-sighted; they were practically ready to fire a gun at the organizational meeting..."

Sanzhu took out his cigarettes, lit them around, and continued to explain to Jiang Xia: "In the end, the ancestor talked to the village secretaries of Qinjiacun and Shangxiawacun. The village secretaries of Shangxiawacun supported the ancestor and decided to send laborers to repair the dam together."

"Oh!" Jiang Xia nodded: "Then, where is Qin Family Village?"

“Look…” Sanzhu pointed to a dazed-looking man beside him, “Uncle Wei from Qin Family Village said he can’t spare that many laborers, and he’s worried that the organization work will be difficult in the future, but he’s offering us moral support…”

"In the end, they probably felt embarrassed, so they sent a man from the village..."

"Bah! That old man Wei is a real rat incarnate! Of all people to send, he had to send a notorious idiot. Young master, look at that guy, he's so dull and wooden. When the ramming hammer was swung, he just stood there dumbfounded, trying to crawl under it!"

"Is this supposed to be helping? It's purely here to disgust us!"

Wu Zhu spat and glared fiercely at the man.

The man was stunned by his fierce tone, his head shrank down, his shoulders hunched over, and he became hunched over.

Hey, another village guardian?

Jiang Xia shook her head. "Alright, don't yell at him. Take your anger out on that guy surnamed Wei!"

He pulled out the remaining two hard candies from his bag, approached the village guard, and opened his palm: "Have a taste..."

This village keeper was quite different from the fat man Jiang Xia had encountered. His large frame was clad in a thin cotton coat, and a gust of wind blew through the holes, revealing his prominent bones.

The village keeper looked at the candy and gave Jiang Xia a big smile.

"Ah... Great-Grandpa, hello!"

Jiang Xia was delighted, stuffed the candy into the man's hand, and squeezed it tightly.

"You're not from Jiangjia Village, so you don't need to call me that. Just call me comrade!"

Just as Jiang Xia was about to say something more, he heard Jiang Qiu let out a disappointed sigh.

"Teacher Liang! According to the calculation results, the relative density (DR) value of the sand layer is currently only 50%, which is lower than the design requirement of 75%!"

Teacher Liang, who was discussing Jiang Xia with Grandma Jiang, couldn't sit still any longer and quickly walked over to Jiang Qiu's side.

"Is the calculation result correct?"

"Yes! I checked it twice, Grandpa Liang, according to the formula you proposed..."

pw?=（m1??m2）/Vx(1+w)?以及pd?=（m1??m2）/V。确定结果正确！相对密度确实是这么多！”

"Hey! Still not working?"

Teacher Liang sighed and turned to Grandma Jiang: "Sister, we need to work harder! This relative density isn't enough to support the weight of a 45-degree dam..."

"We've been ramming it all morning and it's still not working?" Grandma Jiang gave a wry smile. "Looks like I was thinking too simply. I never imagined that there was so much to learn about building a small dam!"

"There's no other way. The soil here is a mixture of loose sand and silty clay. The compaction standard for the core seepage prevention zone of the dam should be greater than 98%. Otherwise, the lifespan of this dam might not even be three years!"

Teacher Liang sighed: "Sister, let's not talk about making it a century-old project, but it should at least last for 50 years! Otherwise, we'll really be letting down the hardworking members of the commune."

"Hey! Grandma, Teacher Liang, don't worry, Jiang Xia seems to have drawn up some blueprints for a road roller. Once he finishes making the machine, it will definitely meet your needs!"

Looking at the anxious group, Old Wang pointed to Jiang Xia, who was correcting the way the village guards addressed him, and said with a smile.

"Oh?"

"what?"

"ah!"

"Big brother is truly a timely help!" Jiang Qiu raised his muddy face and smiled happily at his older brother.
