The five-and-a-half-year-old baby doctor comes to the city to cure those who refuse to listen.

Yan Zhengqing walked away with a tragic expression, carrying that "big brother" mobile phone that was heavier than a brick.

He didn't look like he was going on a secret mission; he looked more like he was going to die a martyr's death.

Lin Jianguo watched his retreating figure, then looked back at the Grandmaster who was busy chopping wood and carrying water in the courtyard. He couldn't suppress the fear he felt towards the Black Lotus Sect.

"Xiao Chen, this Black Lotus Cult sounds very powerful, what should we do..." Lin Jianguo rubbed his hands, his face full of worry.

"Grandpa, don't be afraid."

Chu Chen was squatting on the ground, teasing a passing ant with a small twig.

"When soldiers come, generals will block them; when water comes, earth will dam it."

He stood up, dusted off his trousers, and looked around the entire courtyard of Qianlong Residence with an air of importance.

"However, since they're coming to deliver packages, we need to make sure the door is sturdy enough so they don't make our house dirty."

He turned to look at Zhou Tian, ​​who was supervising the chopping of firewood.

"Zhou Tian, ​​I have a task for you."

Upon hearing this, Zhou Tian immediately tucked the leather whip in his hand into his waistband and jogged over.

"Sir, what are your orders?"

"Go to the stone quarry outside the city and buy me a batch of stones."

Chu Chen pulled a crumpled piece of paper from his pocket. It had several oddly shaped stone designs drawn on it, along with their dimensions.

"I want this kind. It should have natural moss on the surface and look a bit old. The appearance doesn't matter, but it must be hard enough."

Zhou Tian took the blueprints and scratched his head.

"Sir, are we... doing landscaping?"

"No, our home's decor is too outdated. I'm going to upgrade it."

Chu Chen was talking nonsense with a serious expression.

"Go for a modern Chinese style, emphasizing understated luxury and sophistication."

Zhou Tian nodded as if he understood, then grabbed the blueprints and ran off excitedly.

Lin Jianguo looked at his grandson, opened his mouth, but in the end he didn't ask anything.

He's gotten used to it now; it's okay if he doesn't understand what his grandson is saying.

In the afternoon, Zhou Tian drove back in a large truck, loaded with a load of oddly shaped bluestones.

"Move them all down and place them in these spots in the yard, according to the lines I drew."

Chu Chen was directing the group of "labor reform prisoners" in the backyard.

Zhao Wuji, Zhao Tiansha, and those international spies all put down their work and, with bitter faces, began to work as porters.

Each of these stones weighs hundreds of kilograms, but in the hands of these former masters, they were as easy as moving a few blocks of tofu.

Following the white lines drawn by Chu Chen on the ground, they precisely placed the bluestones in various corners of the courtyard.

Some were placed next to the artificial hill, some were buried in the flower bed, and some were even embedded directly in the corner of the wall.

All afternoon, the muffled thuds of stones hitting the ground echoed throughout Qianlong Residence.

Lin Jianguo, holding a teacup, stood to the side, completely bewildered.

He noticed that the place where Chu Chen had placed the stones looked messy and lacked any aesthetic appeal, making the yard even more chaotic.

Chu Chen ignored all of that. He moved a small stool, sat in the middle of the courtyard, and slowly carved something on a boulder in a central location, holding a carving knife he had somehow acquired.

The carving knife moved with more ease in his hands than cutting butter, stone chips flying everywhere, and intricate and mysterious patterns gradually took shape on the stone.

As Zhao Wuji carried the last stone, he glanced at Chu Chen as he passed by.

With just that one glance, he felt as if his soul had been pricked by a needle. An indescribable, chilling killing intent emanated from the patterns, causing his hand to tremble and nearly causing the hundreds-of-pounds-weight stone to fall on his foot.

He quickly looked away, nervously placed the stone in the designated spot, and then moved far away, not daring to look at it again.

As it was getting dark, the stones were finally all arranged.

Chu Chen then had Zhou Tian move all the rare ores he had previously brought from the Xuanyao Valley pit to the backyard.

He hastily built a makeshift furnace with a few firebricks and threw all the colorful ores into it.

"Director Zhao, come here and lend a hand." Chu Chen waved to Zhao Wuji.

Zhao Wuji ran over with a fawning expression.

"Sir, what can I do for you?"

"What are your instructions?"

"Aren't you using fire-attribute internal energy? Come on, blow some air into this furnace for me."

Chu Chen pointed to the stove.

"Control the heat carefully, first use a gentle heat to smelt, then switch to a strong heat to forge."

Zhao Wuji's face immediately turned green.

To make him, the former master of Xuanyao Valley and a half-step grandmaster, a human fan?

But he dared not disobey, so he could only grimace, gather his inner strength, and carefully channel his true energy into the furnace.

He was surprised to find that the ores Chu Chen threw in each had vastly different melting points and properties, making it impossible for them to be smelted in the same furnace.

But Chu Chen would only occasionally throw in a herb or drip a few drops of an unknown liquid, and the violent energy would miraculously merge together, turning into a pool of liquid shimmering with nine-colored light.

Zhao Wuji's worldview was once again thoroughly rubbed into the ground.

Chu Chen's movements were as fast as lightning. Using two tree branches as pliers, he quickly pulled out more than a dozen thin, cicada-wing-like metal pieces shaped like willow leaves from the pool of liquid.

As soon as the metal sheet was removed from the flame, it cooled rapidly and turned into an ancient bronze color.

"Alright, that's a wrap."

Chu Chen clapped his hands.

Zhao Wuji was exhausted, his internal energy almost completely depleted. He plopped down on the ground, panting heavily.

The next morning, Lin Jianguo got up and found that the yard had changed drastically.

Those messy stones now look much better, as if they've been carefully arranged.

Even stranger, a string of wind chimes appeared under the eaves of the east wing.

The wind chime was made by stringing together the bronze willow leaves that had been refined yesterday. It had a strange shape, and when the wind blew, it didn't make a crisp "ding-dong" sound, but a dull "humming" sound that made people feel uneasy.

"Xiao Chen, why did you hang that thing up? It sounds awful."

Lin Jianguo pointed to the string of wind chimes and asked.

Chu Chen was sitting at the stone table drinking AD calcium milk when he heard this, and put down the bottle with a serious expression.

"Grandpa, you're so out of touch."

"This isn't called a wind chime; it's called the 'Qianlongju Smart Home Security System 1.0'."

Lin Jianguo was stunned.

"What...smart home?"

"Yes." Chu Chen pointed to the stones in the yard. "See those stones? Those are our central server and distributed sensors."

He then pointed to the wind chimes under the eaves.

"That's a voice-controlled drone defense matrix."

"Simply put," Chu Chen summarized, "fire prevention, theft prevention, and cult prevention. From now on, if any unruly flies fly in, we won't even need to lift a finger; it'll be automatically cleaned up."

Lin Jianguo was completely confused. He recognized each word individually, but couldn't understand them at all when they were put together.

He was stunned for a long time before he finally managed to utter a sentence.

"Wow...wow, modern technology is so amazing."

Chu Chen looked at his grandfather's bewildered yet impressive expression and nodded in satisfaction.

He picked up a brick that was left over from moving stones yesterday.

"Here, let me demonstrate for you."

He cleared his throat and called out to the wind chimes.

"Xiao Ai, my classmate."

The wind chimes did not respond.

Chu Chen wasn't embarrassed and simply changed his wording.

"Tmall Genie?"

The wind chimes remained silent.

"Cough cough." Chu Chen coughed twice, then let out a low shout in an ancient syllable.

"punish!"

He casually threw the brick in his hand toward the center of the yard.

A bizarre scene unfolded.

When the brick flew directly above the yard, it vanished into thin air without any warning.

It wasn't an explosion, it wasn't shattered, it was completely and silently wiped from this world, leaving not even a speck of dust behind.

The teacup in Lin Jianguo's hand fell to the ground with a "clatter" and shattered into pieces.

He rubbed his eyes, stared intently at the center of the courtyard, his mouth agape, but he couldn't utter a single word.

Not far away, Zhao Wuji, who was watering the vegetable garden, witnessed this scene.

The water ladle in his hand fell into the bucket with a "plop," splashing water everywhere.

He felt a chill run from his tailbone straight up to the top of his head.

He stiffly turned his head, looked at the seemingly ordinary bluestones, and then at the unremarkable wind chimes under the eaves. Cold sweat instantly beaded on his forehead.

The Nine Heavens and Ten Earths Extinction Formation!

There's also the ancient sword energy of the Immortal Slayer!

This kid actually brought these kinds of killing formations and weapons that only exist in myths and legends into the yard and used them as decorations!

It's voice-activated!

He suddenly realized that being the head of the outhouse at Qianlongju wasn't so unacceptable after all.

At least, he's still alive.

"Hmm, it seems the system is well-tuned; the signal is quite stable."

Chu Chen clapped his hands in satisfaction, then turned to look at Zhao Wuji, who was stunned.

"Chief Zhao, what are you standing there for?"

"The vegetables are practically dying of thirst, aren't you going to water them?"
