"Why does it turn light into fire?" Shanzhi followed behind Ye Chang and babbled. Although Ye Chang had explained it many times, he still couldn't understand it. "I once took ice in winter and accidentally discovered that the ice with a convex arc surface can condense the light into one, and the triangular ice strips can disperse the light into three" Ye Chang said while talking. Think about what will happen in the palace now. This is a relatively open-minded Tang Dynasty, and people are very tolerant, so Ye Chang is not worried that if he tells this, he will be regarded as a monster. "Let people go to the ice cellar." Get ice inside. "In the palace, Li Longji said to Gao Lishi. "When Chen Xuanli arrived, he also brought the ice. First it was a convex mirror. As Ye Chang said, it actually focused the sun's rays into one point, and after a while, , then the fire was successfully made. "It is true that this is the case I have to summon my son-in-law Zhang Pei to come whoever is on duty in the Hanlin Academy today will be summoned." " Discovering that not only water jade balls can ignite fire, but also convex ice mirrors can ignite fire. Li Longji began to believe that this was not a witchcraft. It was just like water flowing downwards and trees growing upwards. It is a natural principle. " After a while, Zhang Pei appeared in front of him, but he was on duty at the Hanlin Academy, but he hadn't arrived yet. "Who is on duty at the Hanlin Academy today? "Li Longji asked. "Li Taibai. " Zhang Pei replied. "Where are the people? " Zhang Pei was a little annoyed. He didn't know where Li Taibai, who was supposed to be on duty, had gone. Gao Lishi, on the other hand, tilted his lips and said, "Xueshi Li likes excitement. Did he also go to the city game and hang out there? " "Even I want to go and see it. "At this time, Li Longji was quite tolerant of Li Bai. He smiled and said: "In that case, I will send people to the market place to summon him. " Zhang Pei listened to Li Longji's arrangements calmly, but he was a little jealous of Li Bai. "Xian son-in-law, you preside over the Hanlin Academy, have you ever seen this? " "Where does this come from? "Seeing Chong Niang aside and thinking about what happened in today's city game, Zhang Pei immediately understood that this must be Ye Chang's fault. Moreover, he presented this "treasure" to the emperor through Chong Niang, and he must have wanted to ask for it. Li Longji was so happy that he could get an official position. Thinking of this, Zhang Pei saluted Li Longji and said: "Your Majesty, this is a witchcraft. How can it be kept in the palace? Those who offer this witchcraft must be punished." Li Longji. He stroked his beard and smiled: "Isn't this a sorcery? " "How is this not a witchcraft? "Zhang Pei was stunned when he heard this. The emperor was very afraid of someone in the palace using witchcraft to confuse people and harm others. Emperor Wu of the Han Dynasty was a talented man and he also killed his own prince because of witchcraft. In this regard, Li Longji's character was close to that of Han Wu. "A good son-in-law. Don'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 take advantage of this matter to get Ye Chang in. How could he be in the mood to think carefully? He shook his head: "It's not sorcery, it's also a strange skill. The clever ears cannot be heard by the emperor or the scholar-bureaucrats. " This dampened Li Longji's mood, especially when Li Longji saw Chong Niang standing there pitifully and thought that he had just frightened his little daughter. He smiled and waved his hand: "Xian son-in-law, you still need to learn more. . " First, the convex lens gathers the fire, and then the prism splits the light. Of the two, Yang Yuhuan is very interested in the latter. At this time, he smiled and said to him: "Sanlang, if you use this prism to split the light during singing and dancing in the Liyuan, it will shine on Wouldn¡¯t it add more color on stage? " "But you need to move with the music" The two of them discussed with great interest how to use prisms to separate the light on the stage. After a while, they heard the sounds of the little eunuchs, and then they saw Two young eunuchs helped a man come in, and they smelled the smell of alcohol from a distance. "Li Longji smiled and said: "I'm so drunk, I don't know if I can still speak. " "I'm not drunk, but just a little tired. "But the man pushed the little eunuch who was supporting him away, stood up unsteadily, and saluted him: "Today's market competition, there are a total of forty-seven kinds of fine wines. In the past, it took a lot of time to buy them one by one. With all my strength, I got together in one place today, and I became greedy. Please forgive me. " He has slender eyebrows and long eyes. He is handsome, elegant and unrestrained. Although he is drunk in Gu Panjian, he is still drunk. It is Li Taibai. " Since Li Qing is not drunk, please tell me what is going on. I just asked Academician Zhang, but he didn't know either and thought it was a witchcraft. " Li Longji signaled to Gao Lishi. Gao Lishi instructed the little eunuch to get ice again, use a convex lens to make fire, and use a prism to split the light. When the others saw this scene, they all exclaimed. Li Bai looked at it with sleepy drunken eyes. He smiled and said nothing. "Li Qing?" "Li Longji asked. "Convex lens to make fire, this must be practiced by Wu Yechang. "Li Bai's first sentence made everyone smile.Laughing, but the second sentence is a bit surprising: "The Yang Tunnel used in the army has the same principle. "Book of Rites" records that 'the left side wears a golden sui', which is also of the same type. "Huainan Wanbi Shu" There is also a saying in "Peel the ice to make it round, hold it towards the sun, and use moxa to bear its shadow, and the fire will be born." Speaking of this, Li Bai glanced sideways at Zhang Pei, and then said with a smile: "Scholar Zhang." Proficient in calligraphy and calligraphy, this kind of idle writing is not what a bachelor is good at." Zhang Pei was speechless. He originally regarded it as a sorcery thing, but he didn't expect it to have such an allusion. He can be regarded as knowledgeable, otherwise he would not be in his current position, but compared with Li Bai, he is still far behind. Li Bai read a lot of books and had a strong memory. He could pick up such allusions at his fingertips as if he had a scroll at his side. However, although Li Bai was kind-hearted in helping him, he did not appreciate it. He lowered his eyes and stopped looking at Li Bai. Li Bai was careless and did not pay attention to this detail. He pointed to the prism to separate light and said: "Kong Yingda of the imperial dynasty annotated the "Book of Rites" and wrote the marginal note of "HL" in the "Moon Order". When the sun shines, the raindrops form a rainbow. Is it possible that the raindrops are also ribbed, so the sunlight forms a rainbow? After he finished speaking, he couldn't help but laugh: I only know that I am in the Hanlin Academy, drinking alcohol every day, but I don¡¯t know that I am also well-read. I am a very human being. The more you drink, the deeper your wisdom becomes. Please give me some wine. "This is almost his normal state. Every time he drafts an edict, writes a beautiful article, or prepares Li Longji as an advisor, he has to ask for a drink from Li Longji. Li Longji laughed, feeling very happy in his heart, but also sighed a little. It turns out that it¡¯s not that Ye Chang has any sorcery, but that it¡¯s something that everyone in the past knew, but even though it was obvious to them, they didn¡¯t make use of it. ¡°Why did you know it was Ye Chang¡¯s doing it as soon as you saw it? "Li Longji asked with a smile. "Everyone in the world is mediocre, but Ye Shiyi is clever and can find these truths in ancient books. He is also a good person. He sees this principle and must practice it. "Li Bai said. "Qing and Ye Chang know each other? " "We have known each other for a long time and have never known each other in our lives. " Li Longji nodded, and suddenly something moved in his heart. Ye Chang's clever ideas were very helpful to his Liyuan actors. Maybe he should give this kid a chance? But looking at Chong Niang who was smiling at the side, Li Longji changed his mind again. He couldn't give this guy a chance to get close to Chong Niang. Although Chong Niang was still young, he had been in Chang'an for a long time. Won't Chong Niang start to grow up in another two or three years? "Since we have been friends for a long time, I will ask you to do something for me. Li Longji looked at Li Bai and said, "Please go see this Ye Chang for me." " Li Bai was overjoyed. He had long wanted to make friends with Ye Chang, and just now he wanted to take this opportunity to recommend Ye Chang to Li Longji. Now from Li Longji's tone, he thought he wanted to summon Ye Chang, so he couldn't help but be happy for Ye Chang. " Zhang Peize It's a completely different mood. Having Li Bai in the Hanlin Academy already makes him feel threatened. If there is another Ye Chang, he feels that it may affect his status in front of Li Longji. What's more, Ye Chang and Ye Chang. His discord was clear. Therefore, when he heard that Li Longji asked Li Bai to see Ye Chang, he felt extremely jealous. If he hadn't known that Li Longji was stubborn, he would have wanted to. At this time, he opened his mouth to block Li Longji's decree. Li Longji pondered for a moment, and then said with a smile: "There is no need to announce the decree. You can ask him for me why he came to Chang'an again after I asked him to return to his hometown. " As soon as these words came out, Li Bai was stunned, while Zhang Pei was overjoyed. "Your Majesty Ye Chang has a genius, your Majesty" "It's just some strange skills. Your Majesty repelled this person, and Yao and Shun were not as good as him." At this time, Zhang Pei felt that his opportunity had come: "This generation is accustomed to making mysteries and confusing the emperor with novel things. One day Qi Heng learned a lesson, and your majesty should be careful about it." Such a righteous speech, although Li Bai has Biancai, but Zhang Pei is his immediate superior, and Li Longji has obviously made up his mind. He did not expect such a turn of events. He was stunned for a moment, and finally suppressed the displeasure in his heart, shook his head and said: "If your Majesty selects Ye I am willing to work hard for Chang Yu in the dust, but if I want to repel Ye Chang, I have Bachelor Zhang to serve. " He clearly refused to chase Ye Chang away, and Zhang Pei was overjoyed when he heard this. "Li Bai's temperament doesn't look like that of a minister. How can he pick and choose and discount the emperor's order? Although your Majesty is now favoring you. Sooner or later, he will annoy His Majesty. At that time, Li Bai's words and deeds will all be blamed. "I am willing to obey the imperial edict. "Since Li Bai refused this job, Zhang Pei naturally did his part and stepped forward to salute Li Longji. The Chong Niang next to her flattened her mouth and looked at Zhang Pei with a very unkind look. "An Lushan was rude to her back then and killed her. Li Longji originally wanted to give her a small punishment for cheating on her chamberlain, but it turned out that Zhang Pei made the remarks, and Li Longji turned his anger into happiness. Now he wants to drive Ye Chang away, and he has made repeated slanders.He is a villain. No matter what, Chong Niang hated Zhang Pei in her heart, even though Zhang Pei was her so-called brother-in-law. Li Longji felt that Zhang Pei was useless if he stayed in front of him, so he immediately asked him to drive Ye Chang away. When Zhang Pei went out, he winked at Gao Lishi, and Gao Lishi understood and quietly cooed at Chen Xuanli. Zhang Pei was very excited after asking Chen Xuanli for a few sergeants. It would be great if he could take the opportunity to kill Ye Chang on the spot. After leaving the palace, he got up. He didn't know where Ye Chang was. He went back to ask the Chongniang. He was afraid that Li Longji would blame him for not following the rules. After thinking about it, he came directly to Wang Jin's mansion. . Since Wang Jin is against Ye Chang, he always knows where Ye Chang is. Just when Zhang Pei was looking for Ye Chang everywhere, Ye Chang himself was humming tunes and had already left the Chang'an city gate. The monk felt that the carriage was stuffy, so he sat outside the carriage. He turned around with some dissatisfaction and said, "We are so anxious. Didn't Donor Hu treat us to a drink?" Are you waiting for someone to rush you?" Ye Changhuan said happily: "The matter is done. We have obtained Princess Yuzhen's two farms and Wang Yuanbao 30,000 yuan. We have gained a lot from this trip. Let's leave early to avoid surprises." I didn't expect Zhang Pei to come here to cause trouble, but I just stayed in Chang'an for a long time and really wanted to go back to practice martial arts. His sister has been pregnant for a long time and will give birth in more than a month, so of course he has to rush back. These days, when a woman gives birth, it's like going through hell. Although he has made preparations in advance, he is also worried about accidents. With him by your side, you will always feel better based on your experiences from another life. The carriage left Chang'an from Yanxing Gate. At this time, it was getting dark. According to Ye Chang's plan, he would first rest in Nilu where he had stayed before. After dawn, he would take a boat and go back to Wuhan directly along the canal re-dug by Wei Jian. Zhi. When I came here, Jiao Sui and Du Fu were there, which was quite lively, but now Jiao Sui has gone back to his home to visit, while Du Fu stayed in Chang'an City to prepare for the imperial examination, and only Ye Chang and Shan Zhi were left. However, just when the reverse journey was in sight, suddenly, behind them, there was the sound of rapid horse hooves. Shanzhi looked back and said "Huh". He saw a dozen people approaching on horseback. They all looked like powerful servants, but both their riding posture and their expressions were fierce. This group of people began to disperse when they were about a hundred steps away. "Mr. Lang something is wrong. They they have bad intentions." The driver of the carriage was a little panicked. He was just a taxi, but he had seen servants of powerful families running rampant near Chang'an City. Although things were better after Han Chaozong took office in Jingzhao, it was only limited to Chang'an City. Outside the city, it was not uncommon for powerful families to bully the people. Ye Chang also poked his head out of the carriage and looked back. He didn¡¯t recognize these ten or so people, but judging from their cold and fierce expressions, they not only had bad intentions, but were also fierce. Ye Chang's thoughts changed. He had offended many people in Chang'an City. Could it be that some family sent assassins here? "Whether it is or not, these people must be avoided, otherwise the monk alone may not be able to protect himself. "Go quickly, go quickly," he urged. However, at this moment, I saw someone in the crowd with bows and arrows ready. The carriage driver immediately understood and rolled out of the carriage as soon as he turned over. There was no need for him to lose his life for these two guests. The monk was smart, grabbed the reins, and urged the horse. I could only hear a constant buzzing behind me, and then a thumping sound. Ye Chang, who was in the carriage, immediately fell on the floor as he watched four or five sharp arrows penetrate the carriage and almost hit him. "Damn it, it's our lives Monk, enter the forest." Although it is inconvenient for the carriage to enter the forest, at least it can use the trees to hide from the arrows. Moreover, Ye Chang remembered that passing through this forest was where the counterattack was. Once there, this group of assassins would not be so bold.
