For them, being able to enter the Princess Protector's Mansion is a great honor.

It not only means that their future lives are guaranteed, but also means that they have become the princess's protectors.

Moreover, their families can receive better care and protection, which is undoubtedly what they dream of.

"Thank you, Your Majesty!" The craftsmen shouted in unison, their voices full of gratitude and determination.

Li Shimin nodded with satisfaction, then turned to the little princess, his eyes flashing with pride and expectation.

"Sizi, you did a great job this time." He praised sincerely, "You actually created a treasure like Liuli!"

The little princess shook her head firmly and corrected him, "Yeah, yeah, this isn't colored glaze, it's glass!"

Li Shimin was stunned when he heard this, then he burst into laughter, "Okay, okay, if you say it's glass, then it is glass.

I don't care what it's called, anyway, this thing is a treasure, if you make it, it will be a great achievement!"

He looked at the little princess lovingly, his eyes full of pride and joy.

"Tell me, little Sizi, what reward do you want? As long as you can tell me, Yeye will agree to it."

In Li Shimin's opinion, what he saw was just the finest colored glass!

But since it was created by the little princess, she can call it whatever she wants!

When the little princess heard that Li Shimin was going to give her a reward, she did not ask him for any treasure.

Instead, she pouted slightly in disdain and grumbled in mock anger: "Yeah, don't bother Sizi! Sizi is still busy working."

The little princess said this because in her mind, the most precious treasures in the world are hidden in the little prince.

As for Aye, he's so poor! He can't get anything he wants all day long!

Li Shimin was amused by the little princess's "disgust", but he did not feel unhappy about it.

On the contrary, he was full of curiosity about what the little princess would do next.

Liuli has been successfully produced, so what is she still busy with?

So, he asked curiously, "Xiao Sizi, what other work do you have to do?"

When the little princess heard this, she immediately raised the light bulb in her hand excitedly.

He proudly showed it to Li Shimin: "Yeah, look, Sizi is making a light bulb!"

"Light bulb? What is this?" Li Shimin stared at the glassware in the little princess's hand with a puzzled look on his face.

Because in his opinion, what the little princess was holding was still a piece of glass.

Why is it called "light bulb"?

Furthermore, this thing looks complete in appearance, could there be any unfinished work?

The little princess looked at Li Shimin's puzzled expression and giggled.

"Yeah, what you see is just the outer shell of the light bulb. There's nothing inside yet."

As she spoke, she gently rotated the bulb shell in her hand, revealing the cavity inside.

"A real light bulb requires a special filament placed inside this glass shell..."

The little princess's explanation was clear and well-organized.

He explained the principles and process of making the light bulb to Li Shimin one by one.

However, for Li Shimin, this unprecedented professional knowledge seemed to come from another world.

He listened with a bewildered look on his face. Those unfamiliar terms echoed in his ears, as obscure and difficult to understand as the Book of Heaven.

But he understood the little princess's last sentence.

"When Sizi makes the light bulb, the nights of my Tang Dynasty will be as bright as day!"

He asked in surprise, "Sizi, are you saying this light bulb can replace candles? And last longer and be brighter than candles?"

The little princess nodded seriously, "Mucuo, yeah!

Not only does this bulb make the night as bright as the day, but it also doesn't need to be constantly replaced like a candle.

As long as it’s plugged in, it glows continuously, much brighter than a candle.”

After hearing this, Li Shimin was very excited.

He imagined that the imperial palace, streets, and every household in the Tang Dynasty were all lit up with such light bulbs. What a spectacular sight that would be!

This is not only an innovation in lighting tools, but also a symbol of the progress of Tang Dynasty civilization.

"Sizi, when will this light bulb be completed?" Li Shimin asked anxiously.

The little princess tilted her head and thought for a moment before answering, "It will be fine once we produce qualified light bulbs!"

As she spoke, she waved the one in her hand and continued with a hint of disdain, "Although this one can be used, it has too many impurities, and the effect won't be very good!"

"What? Can it be done now?" But Li Shimin didn't care about striving for perfection.

Hearing that the glass in front of him could make do, he immediately urged impatiently:

"Sizi, why don't you make one out of this first so I can see what the light bulb looks like?"

"As for better ones, just leave it to these craftsmen. They'll give it some time and effort, and they'll definitely be able to make something that satisfies you!"

The little princess couldn't help giggling when she saw Aye's eagerness.

She knew that Aye was impatient and always wanted to see new things immediately.

So she nodded and agreed.

"Okay, since Yeye wants to see it so much, Sizi will demonstrate it to Yeye."

After saying this, the little princess turned lightly and ran into the hall.

"Mother, you're back!"

The moment the little princess stepped into the hall, she caught a glimpse of Empress Changsun who was having a cordial conversation with her sister Lizhi and Xiao Chengyang.

A bright smile suddenly appeared on his face.

She couldn't wait to run towards Empress Changsun and throw herself into her warm embrace.

Empress Zhangsun lovingly embraced the little princess, gently stroking her hair, her tone full of doting:
