"Why does it turn into fire?"

Shanzhi followed Ye Chang and nagged. Although Ye Chang had explained it many times, he still couldn't understand.

"I used to take ice in winter and accidentally discovered that ice with convex arcs on the surface can gather light into one, and ice strips with triangular edges can disperse light into three...

Ye Chang said while wondering what would happen in the palace now.

This is the Tang Dynasty with a relatively open atmosphere. People are extremely tolerant, so Ye Chang is not worried that if he says this, he will be regarded as a monster.

"Please let someone go to the ice cellar to get ice." In the palace, Li Longji told Gao Lishi.

When Chen Xuanli arrived, Bing also took it. First, it was a convex mirror. As Ye Chang said, it actually concentrated the sunlight into a little, and after a little time, it successfully made the fire.

"If there is really such a thing... I'll call my son-in-law Zhang Pei to come... Who is on duty in the Hanlin Academy today? I'll call them together."

After discovering that it is not only the water jade ball that can cause fire, but also the ice convex mirror that can make fire. Li Longji began to believe that this is not a magic trick, but just flowing with water to the lower part and trees to the upper part, which is a natural truth.

After a while, Zhang Pei appeared in front of him, but the person on duty in the Hanlin Academy had not arrived yet.

"Who is on duty at the Hanlin Academy today?" Li Longji asked.

"Li Taibai." Zhang Pei replied.

"Where are people?"

Zhang Pei was a little annoyed. He didn't know where Li Taibai, who should be on duty, went. Gao Lishi tilted his mouth: "Sir Li likes the excitement. Do you also go to watch the city competition and linger in the middle?"

"Even I want to see it." At this time, Li Longji was quite tolerant of Li Bai, and he smiled and said, "Since that's the case, I'll send someone to the city tournament to call him."

Zhang Pei listened quietly to Li Longji's arrangement, but he felt a little jealous of Li Bai.

"Son-in-law, have you presided over the Hanlin Academy? Have you ever seen this?"

"Where does this... come from the magic trick?" Seeing the insect girl aside and thinking about what happened in the city competition today, Zhang Pei immediately understood that this must be Ye Chang's ghost. Moreover, he presented this "treasure" to the emperor through the insect girl, and must have wanted to please Li Longji so that he could get a job.

Thinking of this, Zhang Pei bowed to Li Longji and said, "Your Majesty, this is a magic trick. How can it be stored in the palace? It must be punished for those who offer this magic trick."

Li Longji stroked his beard and smiled: "This is not a magic trick, right?"

"How come this is not a magic trick?" Zhang Pei was stunned when he heard this.

The emperor was extremely afraid that someone in the palace would use magic to deceive the public and harm others. Emperor Wu of Han was very talented and had a great deal of killing his prince because of witchcraft. Li Longji's personality was close to that of Han Wu in this regard.

"The son-in-law doesn't know the reason for this?" Li Longji was too lazy to argue with him and asked again.

Zhang Pei was thinking about how to use this matter to bring Ye Changdou in. He was not in a mood to think carefully. He shook his head: "It is not a magic trick, but also a strange trick. It is not something that the emperor and the literati and officials can hear."

This swept Li Longji's interest, especially when Li Longji saw the insect girl standing there pitifully. Thinking that he had just scared the little daughter, he waved his hand with a smile: "Son-in-law, you have to do more knowledge."

First, the convex lens gathers fire, and then the prism spectroscopic light distribution. Among these two, Yang Yuhuan was very interested in the latter. At this time, he smiled and said to him: "Sanlang, if it was the prism spectroscopic light distribution and shine on the stage when singing and dancing in the Pear Garden, wouldn't it add more color?"

"But you need to be happy..."

The two of them were very interested in discussing how to use prism to dress up the stage. After a while, they heard the little eunuchs making a sound. Then, they saw two little eunuchs walking in with one person.

Even though I was still far away, I smelled a smell of alcohol.

"Li Qing is indeed a fairy in the wine industry. She can't live without wine for a moment." Li Longji smiled and said, "I'm so drunk that I don't know if I can still speak."

"I am not drunk, but I am just a little tired." But I saw the man pushing the little eunuch who was holding away, staggeringly standing, and saluting him: "Today's market competition, there are 47 kinds of fine wines. In the past, I will take time and effort. When I get together today, I will be greedy. Please forgive me for your crime."

His eyebrows were thin and long, his eyes were handsome, elegant and elegant. Although he looked at him, he was drunk but he was drunk and did not fall.

It was Li Taibai.

"Since Li Qing is not drunk, let's talk about what's going on. I asked Mr. Zhang just now, but he didn't know it, and thought it was a magic trick."

Li Longji signaled to Gao Lishi, who instructed the eunuch to take the ice again, used a convex lens to make the fire, and used a prism to disperse the light.

When the rest of the people saw this scene, they were all exclaiming. Li Bai looked at it with his sleepy eyes, but smiled and said nothing.

"Li Qing?" Li Longji asked.

"Cramming the fire in a convex lens is a must-have method for Ye Chang to practice Wu." Li Bai's first sentence made everyone smile, but the second sentence was a bit shocking: "The Yang Tunnel used in the army is the same. The Book of Rites states that the "Left-wrapped gold silence is also the same. "The "Huainan Wanbishu" also says, "Cutting the ice to make the round, lifting it to the sun, and carrying the shadow with wormwood will produce fire."

Speaking of this, Li Bai glanced at Zhang Pei with a slant, and then smiled and said, "Sir Zhang is well-versed in Hanmo, and such idle books are not the director of the bachelor's degree."

Zhang Pei was speechless.

He originally regarded it as a magic trick, but he didn't expect that there would be such an allusion.

He was also knowledgeable, otherwise he would not be able to sit in his current position, but he was still far from Li Bai. Li Bai read a lot of books and had a strong memory. Such allusions were read with ease, as if they were on the side.

However, although Li Bai had kindly offered to him, he did not appreciate it.

He lowered his eyes and stopped looking at Li Bai. Li Bai was careless and did not care about this detail. He pointed to the prism and said, "The National Dynasty's comments on "The Book of Rites" and in "The Monthly Order" the HL side note, "The sun is thin and the sun is leaking, and the rainbow will grow. Could it be that the raindrops are also ridge-shaped, so the sun is a rainbow?"

He talked freely, and wrote his articles freely. After saying that, he couldn't help but smile and said, "Others only say that I am in the Hanlin Academy, drinking wine every day, but I don't know that I am also well-read. I am very awesome. The more I follow the wine, the deeper my wisdom. I also ask Your Majesty to give me wine."

This is almost his normal state. Every time he drafts an edict, writes a beautiful article, or prepares Li Longji for consultant, he wants to ask Li Longji for wine. Li Longji laughs out loud, feeling very happy, and sighs a little.

It turned out that Ye Chang had any magic tricks, but it was something that everyone predecessors knew, but although they were obvious to their predecessors, they did not use it.

"Why did you know that it was Ye Chang's work at first sight?" Li Longji asked with a smile.

"The world is mediocre, but Ye Shiyi is smart and able to find these principles in ancient books. He is also a good person. Seeing this principle, he must practice it." Li Bai said.

"You and Ye Chang know each other?"

"The gods have been in contact for a long time, and I have never lived together."

Li Longji nodded and suddenly felt a sudden change in his heart. Ye Chang's clever thoughts were very helpful to his pears in the Pear Garden. Maybe he should give this kid a chance?

But after looking at the cuckold girl who was smiling aside, Li Longji changed her mind again.

You can't give this guy a chance to get close to the cuckold girl. Although cuckold girl is still young, she has been in Chang'an for a long time. If cuckold girl has two or three years, will she start to grow up?

"Since the gods have been in contact for a long time, I will order you to do something for me." Li Longji looked at Li Bai: "Please go see Ye Chang for me."

Li Bai was happy. He had already intended to make friends with Ye Chang, and just now he wanted to take this opportunity to recommend Ye Chang to Li Longji. Now, after Li Longji's tone, he thought he wanted to summon Ye Chang, so he couldn't help but be happy for Ye Chang.

Zhang Pei was completely in a different mood.

A Li Bai in the Hanlin Academy has already made him feel threatened. If another Ye Chang is added, he feels that it may affect his status in front of Li Longji.

What's more, Ye Chang's discord with him is clear.

Therefore, when he heard Li Longji ask Li Bai to see Ye Chang, his heart was overthrown with old vinegar in Shanxi, so sour.

If he hadn't known that Li Longji was stubborn, he really wanted to speak at this time and block Li Longji's will.

Li Longji pondered for a moment, then smiled and said, "There is no need to announce the imperial edict. Ask him for me, why did I come to Chang'an again?"

As soon as these words were spoken, Li Bai was stunned, and Zhang Pei was happy with his face.

"Your Majesty... Ye Chang has a genius, Your Majesty..."

"It's just some strange tricks and tricks. Your Majesty repels this person, Yao and Shun are not in time." At this time, Zhang Pei felt that his opportunity came: "This generation is used to making mysterious things and confusing the emperor with novel things. One day, you should think about it carefully."

After a lot of righteous words, although Li Bai was eloquent, Zhang Pei was his immediate boss, and Li Longji was obviously determined. He did not expect such a turning point. He was stunned for a moment, and finally suppressed his unhappiness in his heart. He shook his head and said, "If Your Majesty lifts Ye Chang in the dust, I am willing to run for a while, but if you denounce Ye Chang, you will have Master Zhang to serve."

Zhang Pei felt happy again after he clearly refused to drive Ye Chang away.

Li Bai's temperament does not look like a minister? He can still choose the emperor's destiny? Although His Majesty is favored by him now, it will sooner or later make His Majesty disgusted. At that time, Li Bai's words and deeds are all guilty.

"I am willing to obey the imperial edict." Since Li Bai refused to do this, Zhang Pei naturally took the initiative and stepped forward to salute Li Longji.

The cuckold girl next to her turned her mouth and looked at Zhang Pei with great disbelief.

When An Lushan was rude to her and killed her eunuch, Li Longji originally wanted to punish her. As a result, Zhang Pei made a statement, and Li Longji turned angry and happy. Now he wanted to drive Ye Chang away, but he repeatedly slandered him. He really was a villain

No matter what, Zhun Niang hated Zhang Pei in her heart, even if Zhang Pei was her so-called brother-in-law.

Li Longji felt that Zhang Pei was useless to stay in front of him, so he asked him to drive Ye Chang away. When Zhang Pei went out, he winked at Gao Lishi. Gao Lishi understood and quietly whispered to Chen Xuanli.

Zhang Pei was very excited when he asked Chen Xuan to Lixuan. If he could take the opportunity to kill Ye Chang on the spot, that would be great.

He just stood up after leaving the palace. He didn't know where Ye Chang was. He went back to look for the insect mother and asked, but he was afraid that Li Longji would blame him for his actions without a constitution. After thinking about it, he came directly to Wang Jin's mansion.

Since Wang Jin is against Ye Chang, this guy always knows where Ye Chang is.

Just as Zhang Pei was looking for Ye Chang everywhere, Ye Chang himself hummed an untuned song and had already left the Chang'an City Gate.

The monk felt frustrated in the carriage and sat outside the carriage. He turned around with some dissatisfaction: "So anxious, don't Master Hu invite us to have a drink?"

"What's so delicious about the wine? What's more, don't leave at this time, will you be rushed?" Ye Changhuan said happily: "The matter is done. I have obtained two farms of Princess Yuzhen and 30,000 guan of Wang Yuanbao. We have a great harvest on this trip. Let's leave earlier to avoid any accidents."

He didn't expect Zhang Pei to come and cause trouble, but he had been in Chang'an for a long time and really wanted to go back to Xiuwu. His sister had been pregnant for a long time and would have to give birth in more than a month, so of course he had to rush back.

These days, a woman is like passing the gates of hell. Although he has prepared in advance, he is also worried that there will be an accident. He is by his side, and with his experiences in another life, he will always be better.

The carriage left Chang'an from Yanxingmen. At this time, the weather was getting darker. According to Ye Chang's plan, he would rest in peace before staying in peace. After dawn, he would take a boat and follow the canal re-driving Wei Jian and go back to Wuzhi directly.

When he came, there was Jiao Sui and Du Fu was there, which was lively, but now Jiao Sui went back to his home to see it. Du Fu stayed in Chang'an City to prepare for the imperial examination, leaving only Ye Chang and Shanzhi.

However, just as the storm was watching, suddenly, behind them, the sound of horse hooves came.

Shanzhi looked back and said "Huh". He saw more than a dozen people riding horses. Judging from their appearance, they were all powerful servants, but they were both fierce and fierce in their posture and expression.

The group of people began to disperse when they were about a hundred steps away from them.

"Mr....the situation is wrong, they...they have bad intentions."

The driver who drove the carriage was a little panicked. He just took a taxi and saw servants from powerful families rampant near Chang'an City. Although Han Chaozong was better after taking office as Jingzhao, it was only limited to Chang'an City. Outside the city, it was not uncommon for powerful families to bully the people.
