Only the little fat Li Tai stared at Li Xuan with big eyes and stared at Li Xuan for a long time, full of longing.

Seeing that my father and mother were about to leave.

Before Uncle Wang could give him a gift, Li Tai couldn't help but raise his mouth and looked at Li Xuan with aggrieved look on his face.

"Uncle Wang, Uncle Wang, where is Qingque's gift?"

"Forehead!"

Li Xuan was stunned, and a trace of doubt flashed in his eyes.

After thinking for a while, I finally recalled before the little fat man was about to cry.

I seem to have forgotten this little fat man’s gift!

He quickly chuckled, looked at Li Tai and asked, "What does Qingque like?"

"Back to Uncle Wang, I like reading!"

Li Tai replied quickly.

"Reading a book?"

Li Xuan frowned slightly, he didn't have much book collection.

"Don't worry Xuanba, I'm waiting for it today, it's not too late to give Qingque gifts in the future!"

Seeing this, Li Shimin said.

Hearing this, Li Tai couldn't help but look disappointed.

However, Li Xuan had a flash of inspiration in his heart.

"I happened to have something, Qingque must like it!"

After saying that, he turned around and walked into the house.

Soon, he walked out with a small object in his hand.

When Li Shimin, Li Tai and others looked at the object, they couldn't help but look confused.

It's just a handle made of purple sandalwood, with a sandalwood ring on the front, wrapped in a round glass. What's the use?

But they didn't notice it. Li Chengqian, Li Baoding and others had strange faces.

"Qingqin, this object is called a magnifying glass, which is carefully crafted by the ink-treater. Putting this lens on the text can enlarge the text!" Li Xuan said.

“Enlarge the text?”

Li Shimin and Empress Changsun were both full of surprise and suspicion.

At this moment, Li Xuan had already handed the magnifying glass to Li Tai.

He also took out a small book from the coffee table, looked through it, and signaled Li Tai to put the magnifying glass on the words.

"ah?"

Li Tai was shocked immediately.

Sure enough, he saw that the words on the small book actually became so big.

He quickly moved the magnifying glass away, and the text on the small book returned to its original state.

I couldn't help but look full of regret.

"Xuanba, how did this happen?"

On the side, Li Shimin and Empress Changsun were also shocked.

"This matter is just taking advantage of the characteristics of glass, just like a clairvoyant!"

Li Xuan chuckled and did not explain carefully.

Although this kind of thing seems simple, if he wants to explain it clearly to Li Shimin, he may not be able to explain it clearly for a day.

"Thank you, Uncle Wang!"

Li Tai saluted Li Xuan with joy and thanked him.

"Qingque, this magnifying glass can not only enlarge text, but also enlarge the heat of the sun. Therefore, you must not use a magnifying glass to see the sun!"

This time, Li Xuan looked solemn.

"Uncle Wang, can the magnifying glass make the sun big?"

Li Tai looked puzzled.

Hearing this, a trace of helplessness flashed in Li Xuan's eyes.

"Hold the magnifying glass and come out with me!"

Then, he took out a piece of paper from under the table and walked out of the house.

"Yes, Uncle Wang!"

Li Tai held the magnifying glass with a happy face and walked out with Li Xuan.

Behind him, Li Shimin, Empress Changsun and others followed him out with curiosity.

Li Xuan found a place with sufficient sunlight and placed the paper in his hand on the ground.

Then, Li Tai walked over, placed the magnifying glass in his hand on the paper, and constantly adjusted the position.

"Xuanba, what are you doing?"

Li Shimin asked curiously.

"Your Majesty, don't be impatient, you'll know in a while!"

Li Xuan was still staring at Li Tai tightly, without turning his head.

Seeing this, Li Shimin smiled helplessly and looked at Li Tai without saying much.

"Um?"

Suddenly, a white smoke rose from the paper.

Before Li Shimin could ask in surprise, the paper started to burn out of thin air.

"Uncle Wang, the paper is on fire!"

On the ground, Li Tai jumped up, his face full of frightened.

"No need to worry, this is what you ignite!"

Li Xuandao.

"What?"

Li Tai was full of surprise and quickly explained: "Uncle Wang, I didn't use flint to light the paper!"

"It's a magnifying glass that concentrates the temperature of the sun, magnifies it many times, and slowly ignites this piece of paper!"

Li Xuan explained.

This time, Li Tai understood it, stared at the big eyes, glanced at the magnifying glass in his hand, and then looked at the paper on the ground.

This was the first time he used fire to ignite from childhood, and deep in his eyes, he was filled with excitement.

"So, when you hold a magnifying glass, you must not look at the sun, otherwise it will burn your eyes. You should not keep holding the magnifying glass and wandering under the sun, which will ignite something!"

Li Xuan reminded again.

Before, Cheng Chusi and Li Chengqian almost burned his small courtyard!

"Please let Uncle Wang go, Qingque will definitely not look at the sun with a magnifying glass!"

Li Tai said solemnly.

"That's good!"

Li Xuan nodded slightly. He had already said what he should say. As for whether this little fat man would hold a magnifying glass and lit the palace, it had nothing to do with him.

"Xuanba, can you give me more such a divine thing?"

On the side, Li Shimin also came to his senses and looked at the magnifying glass in Li Tai's hand with an inexplicable expression.

"Xiao Xiang, Master Kong, and a group of great scholars have been reading books all year round, so now, whenever the words are too small, you need to lie your eyes on the books to see clearly. Therefore, I want to give some magnifying glasses to these old ministers so that they will not be as hard as reading books!"

"It's OK!"

Li Xuan chuckled and continued, "However, every time I read a book, I need to hold a magnifying glass in my hand. It is too inconvenient. You can ask the ink-treater to make some glasses and wear them directly on your eyes. In this way, those old ministers, whether they are reading or walking, just wear glasses!"

"Glasses?"

Li Shimin's face was once again full of doubt.

"Your Majesty, glasses are made of two pieces of this kind of glass, and they can be worn directly in front of you!"

Li Xuan briefly introduced.

Listening to this, Li Shimin was very interested.

"So, please bother Xuanba!"
