My cultivation disguise has been exposed by Xiao Sizi.

"This is supposed to be the majestic and mysterious Tang Dynasty Immortal Abode?! This is clearly a super shelter that combines gangsters, mad scientists, and a royal daycare!"

Just as Li Chen was feeling frustrated and wanted to set up a soundproof array to get a peaceful sleep,

"Sixteenth Brother~~"

A sweet, soft voice called out in my ear.

Li Chen looked down and saw that Xiao Sizi had somehow run to his rattan chair.

The little girl was covered in sweat, her delicate, fair face flushed. She stretched out her two small, white hands and hugged Li Chen's leg tightly, her clear, innocent eyes blinking as she looked at him, activating her invincible "coquettish and affectionate" mode.

"Sixteenth Brother, Sizi is so tired from running. Sizi wants to eat that glowing red berry from last time~~ Please~~"

As the little ox spoke, it rubbed its fluffy little head against Li Chen's leg.

Look at that adorable little face.

Li Chen's expression of utter despair and disgust vanished without a trace in an instant, like a Sichuan opera face-changing act!

Instead, he wore a radiant smile that exuded the loving kindness of an old father.

"Oh dear, is our little Sizi tired? Does he want some spirit fruit? Yes, yes, yes! Sixteenth Brother will get it for you right away!"

With a flick of his wrist, Li Chen magically produced a large plate of crystal-clear, enticingly fragrant century-old vermilion fruits from his storage bag.

He not only stuffed both hands full of food for Sizi, but also waved to the timid Chengyang over there.

"Chengyang, come here, you eat too. Runan, this reddest one is for you, it's good for replenishing qi and blood."

Just moments ago, the Great Tang Dynasty's Number One Immortal Venerable was complaining about the "daycare center," but now he has completely degenerated into a doting brother with no bottom line.

Standing not far away, Qin Wan'er, who was grinding herbs with a jade pestle, witnessed the entire process of Li Chen's change of expression.

The stunningly beautiful maid couldn't help but cover her red lips with her sleeve, which was still scented with medicine, and chuckled softly.

Those beautiful, watery eyes were full of tenderness and smiles.

Li Chen may appear ruthless and aloof on the surface, but deep down, he is more gentle and protective of his own than anyone else.

Just as this heartwarming sibling feeding session was halfway through...

"BOOM!!!"

A muffled explosion suddenly came from the direction of the east wing!

Immediately afterwards, a thick plume of black smoke shot into the sky, blackening a small patch of the originally clear sky.

"What is it now?! Li Qingque! Are you going to blow up the entire palace?!"

Li Chen was so angry that he almost crushed the vermilion fruit in his hand. This fat guy's experiments have been getting crazier and crazier lately.

"Sixteenth Brother! Sixteenth Brother, I did it! Hahahaha!"

This was accompanied by a burst of manic laughter.

The moon gate of the east wing was suddenly kicked open.

At this moment, Prince Wei, Li Tai, had a blackened, frizzy hairstyle that looked like a chicken coop, his face was covered in soot, and even his magnificent purple robe had several holes burned in it, making him look like a beggar who had just crawled out of a coal mine.

But he didn't care about his image at all; his small eyes shone with an extreme fervor!

Li Tai rushed to Li Chen in three strides, ignoring the black ash covering his body, and held up a dark, cylindrical object with small holes in the middle, along with a densely drawn drawing, in front of Li Chen as if presenting a treasure.

"Sixteenth Brother! Look! I've made that thing you mentioned in 'Illustrated Guide to Winter Clothing for the People'!"

Li Tai was so excited that he danced around and spat out words.

"I used coal ash residue mixed with a specific ratio of yellow mud water, and pressed it into shape in a mold! This stuff is not only extremely cheap, but because it has ventilation holes in the middle, it burns very completely and generates extremely high heat!"

"And this matching tin stove! Combined with the chimney to expel the toxic fumes, this is absolutely a priceless treasure for the poorest people in the world to get through this harsh winter!"

Looking at the familiar "honeycomb briquette" in Li Tai's hand, and the extremely detailed structural diagram of the simple iron stove.

Li Chen's eyes suddenly lit up!

"Well done, Qingque!"

Li Chen slapped Li Tai's shoulder, which was covered in soot, and laughed excitedly, "I knew it! You're definitely a once-in-a-century scientific genius!"

The winters of the Tang Dynasty were extremely harsh. Charcoal was expensive, and ordinary people simply couldn't afford it. Every winter, countless more frozen corpses were found in the mass graves outside Chang'an.

Now, honeycomb briquettes and iron stoves have appeared more than a thousand years ahead of schedule. This is absolutely a game-changer that could completely change the landscape of people's lives in the Tang Dynasty!

Now that the tools have been put to use, the next step is to engage in capital operations and reap the rewards of fame!

"Someone come here!"

Li Chen turned his head and loudly gave orders to the guards outside the door.

"Go to the Cui family mansion in Qinghe immediately and bring Miss Cui Wanqing here!"

Li Chen turned his head and looked at Li Tai, whose face was full of excitement. A wicked smile, a mixture of "profiteer" and "savior," curled up at the corner of his mouth.

"Blue Sparrow, get ready."

"I'll take you now to ignite a flame of technology in this frigid Tang Dynasty, a flame powerful enough to illuminate the ages!"

"Our grand plan for 'science and technology-driven poverty alleviation' officially launches today!"
