Courtyard Houses: The Great Masters of a Nation Hidden Within

One method was to have Section Chief Wang select twelve militiamen with the strongest bayonet fighting skills, and have them charge forward in groups of four.

Gao Jianguo skillfully maneuvered inside, taking down all twelve men without getting a single white spot on himself.

The entire militia team stared wide-eyed, mouths agape, but not a single person uttered a sound.

Gao Jianguo chuckled: "What's my little thing compared to Comrade Lü Junsheng's one battle, where he took down twenty-seven Japanese devils with a bayonet—that's the real god."

Section Chief Wang clapped his hands as he said, "Zhendong, stop belittling yourself. The guy you're talking about is indeed impressive, but I haven't had the good fortune to see him. I, on the other hand, watched your skills with my own eyes wide open."

The militiamen joined in the chant: "Yes, yes, yes!"

A burst of applause erupted.

In his other hand was the gun he had been craving for a long time.

56.5 meters, 100-meter chest target, standing and shooting, ten rapid shots, all hitting the bullseye.

That really set the atmosphere on fire; people were yelling, shouting, and clapping their hands until they were practically broken.

Gao Jianguo was still the same as always: "Hitting a chest target is barely considered passing. It was during the military skills competitions that I really opened my eyes. Machine gunners would be firing rapidly with their machine guns, and they would call out names one by one from a row of head targets, without missing a single one."

Section Chief Wang couldn't take it anymore, so he gave a thumbs up, turned around and left—he wasn't going to be a supporting character anymore.

There's a saying: "Since we're already here..."

Since he'd already exposed himself, Gao Jianguo decided to spend the whole day there and indulge his passion for guns.

Are there any problems with grown men being unable to move when they see a gun?

Just treat it as a vacation.

He enjoyed the shooting so much that he also took on part of the militia training for the day.

He holds the title of deputy captain, so it's fine if he's not here, but since he's here, he should at least do something.

The work he did was nothing more than helping to organize the formation, correct the movements, and calibrate the marksmanship. When he had a spare moment, he would wrestle and twirl with the militiamen, which really made him feel a bit like he was leading troops in the company back in the day.

After finishing work in the afternoon, Gao Jianguo, who had made a fortune in terms of popularity and prestige in the militia, said goodbye, got on his bike, and rode home.

When I got home, I just grabbed a quick bite to eat.

Once the food was stuffed, they started tinkering with the materials for the thermocouple protection tubes.

Gao Jianguo had his eye on gh2747 deformed high-temperature alloy.

As for how I became familiar with this thing, it all started when I was working on my graduation project and messing around with thermocouples in my past life. I found it and wrote it down while looking for information.

GH2747 is an iron-nickel-chromium based precipitation-hardening wrought high-temperature alloy. It can operate at 1,100 to 1,250 degrees Celsius year-round, and can even briefly reach 1,300 degrees Celsius. It can basically meet the needs of K-type and N-type thermocouples.

This stuff is quite strong, has a stable structure, and is excellent in terms of oxidation and corrosion resistance. It's easy to weld, and can be rolled or forged into shape.

A relatively simple method for using thermocouple protection tubes is to roll thin plates into tubes and then weld them on.

Moreover, the amount of thermocouples used is negligible compared to the material itself.

Aviation, petrochemicals, nuclear energy, and metallurgy are where it truly shines, and most importantly, it's not expensive.

Besides iron, nickel, and chromium, the only other ingredient that sounds impressive is light rare earth cerium.

To be honest, it's nothing special. The flint in a lighter is just this thing.

This was actually the second big firecracker that Gao Jianguo planned to set off.

It's inconvenient to do a separate project, and it just doesn't make sense for someone working on automation to talk about metallurgy.

It would be much more logical to promote it by claiming it was a trial production of thermocouple protection tube materials.

This alloy can be dried in a vacuum induction furnace, which matches the current experimental conditions perfectly and is very easy.

This is called "killing two birds with one stone"—it caught them all by the armpit.

Back when he was tinkering with thermocouples in his past life, he felt like he had struck gold with this material. He frantically searched through all the related information, especially the proportions.

I only regret that I didn't fully memorize the national standard GB/T14992, otherwise I'm afraid I would have been stuck in the metallurgical field for the rest of my life.

Thinking of this, Gao Jianguo's heart skipped a beat.

Oh no, oh no, are we going to get deeper and deeper into the pit of metallurgy?

No, no, I studied automation. My family's skill is coding bugs, but making CPUs is my real business!

He shook off those nonsensical thoughts and began frantically searching for information about gh2747.

Thankfully, his brain had been thoroughly tested by the system; otherwise, he wouldn't have been able to extract even a single bit of information.

Just as I was busy, someone knocked on the door.

Gao Jianguo stuffed the notes into the storage room, got up, and opened the door.

An elderly deaf woman was standing outside, clutching something in her hand.

He quickly ushered her inside: "Grandma, if anything happens, just have Sha Zhu run a errand and call me. It's pitch black and freezing cold; if she bumps or falls, I'll be in big trouble."

The deaf old woman smiled, her toothless mouth drooping: "It's alright. Don't let my old age fool you, I can still move around, and my eyesight is still good. It's just that my ears won't listen to me."

As he spoke, he moved over to the stove and sat down.

Gao Jianguo chuckled: "Grandma, I can see that you understand perfectly well; it's not a matter of hearing at all."

The old woman's lips drooped down: "What did you say? I can't hear you!"

Well, so you've given me a lesson right in front of everyone, haven't you?

Anyway, he had almost finished his work, and since the old lady was a rare guest, Gao Jianguo made her a cup of malted milk powder.

The deaf old woman took a sip: "Mmm, it's sweet."

Gao Jianguo shouted, "Drink as much as you like! I still have half a can left. Take it with you later; it'll give you energy."

The deaf old woman nodded: "Yes, it's better than Sha Zhu. Sha Zhu cooks me a few meals a week, but there's no meat."

Although he complained about Sha Zhu, his tone betrayed his pain.

Gao Jianguo knew that this grandmother and grandson were always like this. If you went along with her and started to criticize Sha Zhu, the old lady would immediately change her mood from sunny to cloudy.

He deliberately avoided the question: "Grandma, what brings you here today?"

The deaf old woman picked up the bag in her hand and took out a pair of shoes from it: "My eyes aren't blind yet, and I can tell Zhendong that you genuinely treat this old woman like an elder. At my age, I can't help with anything else, except for these hands which can still move. It's getting cold, so I made you a pair of shoes to warm your feet."

Gao Jianguo didn't lie: "Oh, that's great! I was just worried about my feet getting cold."

She deftly kicked off her shoes and slipped them on, saying, "Grandma, you're amazing! You never even measured my foot size, and these fit perfectly."

The old woman curled her lip again: "Hmph, you've been making shoes for decades. Your ears may not be working properly, but your eyes are still bright."

This old lady really loves to pout, just like a child.

Gao Jianguo chuckled as he took off the shoes and put them away: "I told you when I first moved in that my parents might have even worn the shoes you made when they were making the revolution. Well, this good fortune has now fallen on my shoulders."

The old lady smiled, her eyes narrowing. "Yes, if you don't mind, this old lady will make it for you every year."

"That's wonderful! I'll thank you in advance, even if it's a bit embarrassing."

Gao Jianguo was not at all aloof. If he hadn't already left the army, he really wouldn't have dared to do this, given the rule of "not taking a single needle or thread from the masses."

I chatted with the old lady for a while about the things happening in the yard.

Liu Haizhong brutally beat his second son, Liu Guangtian; Yan Bugui plotted against his eldest son, Yan Jiecheng, with abacus beads; Jia Zhangshi nagged her daughter-in-law, Qin Huairu, to death; and He Yuzhu easily dealt with Xu Damao in the backyard.

Gao Jianguo's eyebrows practically flew off his face as he listened, and he gestured wildly.

By the time the old lady finished drinking the malted milk powder, it was completely dark.

Gao Jianguo picked up the half-empty can of malted milk powder and helped the old lady back to the backyard.
