"Yang Yang, Wan Xia, Yan Weidong, Qiu Zhu, Liu Yuan, Zhao Xian......" Ding Yi said thirty or forty names one by one.

"Stop, how can you have so many teachers? What do they teach you? Where are these people now? Li Er interrupted Ding Yi in time, I have never heard of anyone who has so many teachers, although the teacher screams strangely, but it is also the same as the master.

"Uh. I taught even more, mathematics, physics and chemistry, history, geography and politics, and later divided into arts and sciences, and then it was even more powerful,......"

"Stop, what kind of knowledge are you talking about, why haven't I heard of it?" Ding Yi, who was about to say that he majored in college, was interrupted by Li Er.

"Well, there are all kinds of things, all kinds of things, all kinds of things!" Ding Yi summed it up, it should be so much!

"You kid can't tell me one of them?" Empress Eldest Sun listened a little anxiously next to her, and she didn't say clearly what she had learned for so long.

"Well, then chemistry and physics, can Your Majesty get some saltpeter, water, and two basins of different sizes, and a peeled hard-boiled egg, a bottle with a mouth smaller than an egg, and some paper." Ding Yi has heard a lot about the legend of saltpeter, and for the ancients, it was immortal magic.

"Hmph, I'd like to see what you've learned, and get people ready." Li Er instructed the eunuch to prepare what Ding Yi wanted.

After a while, he took the things he needed, and Ding Yi asked people to pour half a basin of water into the large basin and add half a basin to the small basin.

"Your Majesty, the queen will use chemistry to demonstrate to you next, but please don't be too surprised and stay calm." Ding Yi kindly reminded.

"Hmph, don't say more, start quickly!" Li Er did not accept Ding Yi's reminder.

The kindness was not reciprocated, Ding Yi put a small piece of saltpeter into the large basin without saying a word, and after a few minutes, a trace of cold air came, the effect was not good, and there was too much water. Put some more.

Now it's okay, Li Junxian saw the smoke coming from the basin and took a few steps back, a little unsure what it was, it felt unsafe to get too close. There is an eerie feeling!

After a while.

"Your Majesty, all right, please see, this water has frozen." Ding Yi pointed to the basin and said to Li Er.

"You... You say it's chemistry? "Li Er was shocked by Ding Yi's methods, could he be a spell? Empress Eldest Sun was also shocked.

"Yes, Your Majesty, this is just the simplest use of chemistry, and after this knowledge is advanced, it can easily kill countless people, cough cough... It can make crops grow violently, increase the harvest by several percent, and can also be applied in medicine to treat various diseases, and has a great effect on asthma, wind chill and other incurable diseases. Oh, and asthma is what people call a gas disease. Ding Yiyi was not shocked, and even said that it could cure qi diseases, and I heard that the eldest grandson queen had asthma.

"What do you say! Can this method cure qi diseases? "Li Eryi was anxious when he heard that it could cure qi disease, but Empress Changsun's qi disease was said to be an incurable disease by the imperial doctors, and now that he heard that it could be cured, can he not be in a hurry! I didn't ask how I could kill countless people. Empress Eldest Sun was also excitedly waiting for Ding Yi's answer.

"Well, it's theoretically possible, but the minister's research on this knowledge is shallow, so it is estimated that it will not work for the time being!" Ding Yi really failed chemistry!

"Hmph, what did you learn!" Li Er was suddenly angry, why don't you learn it. Empress Eldest Sun was also disappointed!

"Ah, Your Majesty's knowledge is very troublesome, the minister went through a lot of hardships when he first learned it, but after all, he was unable to do it, but please believe that Your Majesty will definitely study this knowledge to a high level in his lifetime." Although Ding Yi didn't take chemistry classes well, he was just interested in all kinds of experiments.

"Well, let's talk about your physics!" Although Li Er was disappointed, he finally had hope and hope.

"Oh, this physics is mainly to explore some world truths, such as why man can be on the earth and not like the stars floating in the sky; how can one take to the skies? why things always fall to the ground; Why are the flowers so red? Well, this is not! Why do some things float on the water and some sink down? why the sun illuminates the earth; how fire has a temperature; why water cooks food; Why does the kettle bounce frequently; What can I do to rush from Chang'an to Luoyang in one hour; What kind of scene is it outside the sky; What can you use to see thousands of miles away? And how can I talk to people thousands of miles away? These are all things that physics needs to learn. Ding Yi even 100,000 whys, and the people above the hall were dumbfounded.

"None of these are... Should it be? How can anyone else fly like the stars, the sun has light! Li Er was a little unsure.

"Your Majesty, this is physics, and what the minister has learned is how to figure out the reason for these things. It's complicated, but it's fun! Ding Yi said to Li Er.

"Your Majesty, please look!" Ding Yi pointed to the bottle with a mouth smaller than an egg and said to Li Er, and after speaking, he lit the torn paper and threw it into the bottle, and put the shelled egg vertically on the mouth of the bottle.

"Poof." The egg fell in.

"You... How do you do it! Li Er was once again overthrown.

"Your Majesty, this is physics, and this involves the change of air. You may not believe it when the minister says it, so the minister won't say it, it's a bit complicated, you understand, and the political affairs will be delayed! Ding Yi, who didn't want to explain the atmospheric pressure, perfunctory Li Er.

"Hmm... In that case, then you will tell me where your teacher is located? Where is your hometown? Li Er felt that what Ding Yi said was reasonable, and turned back to the original topic, almost forgetting the topic by this kid, his mouth was too sharp.

"Eh, Your Majesty's teachers are also in the global village, the minister really can't find it, otherwise I would have gone back a long time ago, if Your Majesty knew, tell me, and I would have returned to my hometown!" Ask me again, if you say it, it won't scare you to death!

"Hmph, you are bold! How dare you fool me like this! If you don't say anything, I will cure you for the crime of deceit. Li Er was furious, he was really a bad boy.

"Your Majesty, the minister is willing to ask for a death to make His Majesty trust, the minister really doesn't know where his home is! The minister also wants to tell His Majesty, but the minister can't do it! Ding Yi learned Cai Shaofen's expression and cried. I really left a few tears, but I just cried because I thought that I might not see my family for more than ten years or more.

"You..." Li Er looked at the heartbroken Ding Yi and was a little confused.

"Your Majesty, the concubine sees that this kid is also showing her true feelings, it should be true, so don't be angry. He is just a child, and he has immortal merits for Datang, so he cares about what to do. As long as his heart is towards the Tang Dynasty, it will be good if you don't want to be Your Majesty! Empress Eldest Sun was bitterly persuading Li Er on the side.

"Yes, Your Majesty, the minister deeply loves every inch of land in the Tang Dynasty, respects His Majesty the Emperor of the Ages, and does his best for the Tang Dynasty, and the minister does not dare to deceive His Majesty! When the minister studies his knowledge thoroughly, he should be able to find his hometown, but now the minister can't do it. Ding Yi hurriedly followed the words of Empress Changsun and said sincerely, leaving a few sad tears from time to time.

"Hmph, I believe you this time, hurry up and study your knowledge!" Li Er also said along the steps, otherwise, if he killed him, no one would be able to come up with a cure for Guanyin's qi disease, and no one would be able to study how to make people fly to the sky, let alone come up with something that would double the harvest and easily kill countless people.

"Thank you, Your Majesty. The minister must do his best, diligently and tirelessly study the knowledge of the minister! Ding Yi immediately promised, otherwise he was afraid that it would be difficult.

"Your Majesty, the concubine thinks it is better to send him to study in the Guozijian, so that he can study more diligently." Empress Changsun felt that she had to let this flamboyant kid be imprisoned, and she could also let him know that she was polite, righteous and shameful, and that she was no longer as naughty as this.

"Ah, mother, don't! I don't want to go to school, I'm going home to study physical chemistry! ”
