The sun was very strong, and the Persians cast the light refracted by the glass mirror on the thatch, but nothing happened. How could it be related to the fire in Lishan Villa?
While the courtiers were puzzled, Niu Xiantong, the general manager of Lishan Villa, had a flash of panic in his eyes.
"Non-my family, its heart must be different!"
"Your Majesty, this Persian is playing tricks. I thought he was an assassin who sneaked into the palace..."
The cattle steward knelt on the ground, trying to block the Persian's next move, but it was too late. The thatch first started to smoke, and then suddenly burst into flames.
The sun was already strong in late summer and early autumn, but just like that, a small bundle of thatch was burned to ashes in the blink of an eye where the courtiers could see it.
"If an assassin sneaks into the palace, General Li is here and will protect my father."
After the bundle of thatch was burned, Li Sixu looked at the father-in-law and asked in a childish voice: "What was the father-in-law worried about just now?"
"This old slave is also worried about His Majesty's safety."
Mr. Niu's face turned a little pale, and he obviously couldn't hold it any longer...
If you shine a small glass mirror on the thatch, the thatch will catch fire on its own?
This left the courtiers stunned and shocked for a moment.
The same is true for Xuanzong!
The breeze stirred up the ashes of the burned thatch, and Xuanzong recovered from the shock: "What kind of secret technique is this?"
"Your Majesty, this is not an immortal technique!"
Li Linhuai followed what Li Sixu taught her and explained the principles of concave and convex mirrors.
The point where the concave mirror reflects sunlight is called the focus, and the temperature is high enough to cause thatch and wood sticks to burn.
A convex mirror is also called a magnifying glass. When sunlight passes through the convex mirror, it will gather at one point and the temperature will be quite high, which can also cause thatch and wood to burn.
What is a concave mirror and a convex mirror? Not only was Xuanzong confused, but the courtiers were also confused by Li Linhuai.
Xuanzong asked the Persians: "Tell me, why does a glass mirror catch fire when it shines on thatch?"
The Persians didn't understand the language, so they chattered a lot.
Afraid that Xuanzong wouldn't understand, he kept polishing the mirror, and then held the mirror and shook it in the sun. In the end, not only did he fail to explain clearly, but it made Xuanzong even more dizzy.
However, not understanding what the Persians said did not prevent Xuanzong and his courtiers from thinking that the fire in Lishan Courtyard was related to the glazed mirror.
Xuanzong looked at Li Linhuai and continued to report: "It was a coincidence that I saved this Persian who was being hunted and got a glass mirror from him."
"Although colored glaze is expensive, I saw that it cannot be used to illuminate people. It is not as practical as a bronze mirror. Thinking that the ten princesses were frightened in the royal courtyard, I brought this colored glaze mirror to the princess. Relieve boredom."
"The little princess was playing with a mirror and burned it on the thatch pile next to the woodshed. I thought it was strange. I learned from the Persians that the glazed mirrors he sold had just arrived in the capital and were sold out, so I followed this clue. , it was found on Huangshang Wang Yuanbao."
Li Linhuai cupped his hands and said, "I have brought Wang Yuanbao. Please summon him."
Xuanzong asked Eunuch Yang to send Wang Yuanbao to see him. Soon Wang Yuanbao, who was fatter than Manager Niu, climbed up the steps of Jinluan Hall step by step. He glanced at Li Sixu and knelt down to pay homage to Xuanzong.
"Caomin Wang Yuanbao, I have met His Majesty!"
"The glazed mirrors brought to Chang'an by Persian merchants were indeed bought by the common people."
Wang Yuanbao reported: "The Caomin Mansion has always been in contact with the father-in-law who is responsible for the procurement of the Internal Affairs Office in the palace. He helps the Internal Affairs Office collect rare items sold to the capital by foreign merchants at very low prices, such as those brought by Persian merchants. The ambergris that came to the capital was purchased by the Cao Min Mansion for the palace."
"These foreign merchants who come to the capital to sell goods also know that when they have rare items, they first send them to the people's houses. These glazed mirrors were bought by the people."
Wang Yuanbao suddenly looked at Eunuch Niu: "After getting the glazed mirror, the grassroots quickly informed the Ministry of Internal Affairs. It was this father-in-law who took the token from the palace and bought the glazed mirror from the grassroots at a very low price. If he threatens ordinary people and still wants to do business in the capital, then he should not publicize the fact that he bought a glass mirror."
Ever since Li Linhuai asked the Persian businessman to use a mirror to light the thatch on fire, Mr. Niu was frightened and had been thinking hard about how to deal with it.
So much so that Li Linhuai asked Xuanzong to pass on Wang Yuanbao, but he had not yet recovered.
Those batches of glazed mirrors were indeed obtained from the Royal Shang Wang Yuanbao, but murdering the royal heirs was no small matter. The mirrors only got to him after changing hands several times.
When he heard Wang Yuanbao say that he bought it with the palace sign and threatened him, Mr. Niu was stunned!
"Your Majesty, I have never bought a glass mirror from him. It is this businessman who smells like copper who is framing me."
"Do you dare to say that Mr. Niu has a clear conscience about almost burning the little princess to death?"
Li Linhuai knelt down and said, "Your Majesty, while Mr. Song summoned Eunuch Niu to the capital yesterday, I went to the Royal Courtyard and arrested Eunuch Niu's accomplices."
"The palace maid herself admitted that it was the Niu Gonggong who ordered her to set fire to the wooden bridge connecting Yahe Garden with a glazed mirror, intending to burn the little princess to death."
Niu Xiantong thought that setting fire to Yahe Garden was done perfectly. The glass mirror changed hands several times and everyone who handled it had dealt with it.
As an imperial merchant, if Wang Yuanbao knew that the colored glass mirror for sale was related to the murder of the tenth princess, he would definitely cover up the matter of handing over the colored glass mirror.
As a result, he calculated countless times and failed to calculate that the Persian merchants could escape death.
Wang Yuanbao was not afraid of being implicated and went to court to testify.
What's more, Mr. Song and Li Linhuai teamed up to make a plan to divert the tiger away from the mountain and attack the people around him while he was leaving the Royal Courtyard.
In this way, even if Liuli Jing who murdered the tenth princess could not be found, he had already fallen into the urn.
The situation is over!
The ox's face was ashen and he sat paralyzed on the ground...
"Your Majesty, Manager Niu has no grudge against the little princess, so why did he do this to the little princess? I think Niu Fairy Tong was just one of the real culprits behind setting fire to the little princess. I hope your Majesty will investigate the case thoroughly."
After Li Linhuai finished speaking angrily, Xuanzong said: "I will let Yang Sixu investigate the case thoroughly."
Returning to the Jinluan Hall, Xuanzong looked around at the courtiers with a gloomy expression, and asked: "Let me see, who else wants to obstruct vaccination to prevent smallpox?"
The whole hall was silent, and there was no sound!
"Since all my dear friends agree with the vaccination of cowpox to prevent smallpox, if anyone dares to interfere and cause trouble, he should be punished!"
Xuanzong's majestic voice echoed in the hall, and Lord Yao and Lord Song all came out in unison: "Your Majesty is wise!"
"Your Majesty, Holy Might!"
"Your Majesty, Holy Might!"
All the courtiers in the palace knelt on the ground, supporting vaccination to prevent smallpox. Li Sixu and Wang Tao looked at each other, and Wang Tao smiled happily at her with a loving look on his face.
Li Sixu winked at him mischievously, and then saluted Xuanzong: "Father, I still have something to say."
