Seeing that the experiment was finally successful, Chen Yi felt relieved and signaled the palace servants to put out the burning fire. Then he walked to Wu Zetian, wiped away the sweat from his face, and respectfully said: "Empress, I didn't say a big word, I took the fire with ice. Hehe, the skills I have shown are also a trivial skill. Please don't laugh." As he said that, he looked at Ming Chongyan, who was still full of surprise.

"Zi Ying, you are so amazing. You can actually use ice to remove fire. Tell me quickly how you did it." Wu Zetian looked at Chen Yi with a smile and signaled Wu Tuaner who was slapping her palm to go over to wipe the sweat for Chen Yi. Wu Tuaner responded and carefully wiped the sweat on Chen Yi's face and belly, which made Ming Chongyan on the side jealous.

Chen Yi knew that Ming Chongyan was also a "nature" person and a lustful person. He could guess from the fact that he saw Ming Chongyan's performance when he was watching the side. Just now, when he was in the hall, Chen Yi saw him aiming at Wu Zetian's half-exposed breasts at least several times, and occasionally looked at Wu Tuan'er's equally high chest. The surging chests of these two women are indeed eye-catching, but people like Chen Yi can already hide their hopes. Those malicious eyes can not be seen by others except the parties involved. However, Ming Chongyan's performance is as eager as Ming Chongyan, and he can't help but peek at the scenery of the woman's chest next to him.

When he saw Ming Chongyan aiming at Wu Zetian and Wu Tuaner's chest, Chen Yi wanted to use a hammer to knock him hard on the head, shouting loudly, and not seeing whose woman he was, but you can watch it randomly? However, Wu Tuaner's extremely considerate sweat-wiping behavior just now hit Ming Chongyan. The pretty palace maid next to Wu Zetian was too lazy to even look at him directly. However, he served Chen Yi so carefully that anyone's charm could be seen at a glance.

She smiled brightly at Wu Tuaner. When the beauty was shy, Chen Yi began to answer Wu Zetian's inquiry: "Empress, it's not just ice. Things that look similar to this ice cube are like the lens in a telescope, and also have the function of aria. Just now, I made the ice cube into a convex mirror. This shape can gather light, which is the bright white dot just now. The white dot that gathers sunlight is very high. Even in winter, it is the same. It can easily ignite those dry things. If such a mirror is placed on the house and the point is gathered on flammable wood and other objects, it may cause a fire."

"So that's it. I've seen it, haha," Wu Zetian said with a smile. After Chen Yi said this, it was really easy to understand, and he also praised him: "Zi Ying, you know a lot of techniques, and no one knew about them before."

"Empress, in fact, it is not only such a convex mirror that can concentrate and ignite objects, but a concave mirror can also be used. However, the concave mirror is focused by reflection, and the principles are different." Chen Yi then told Wu Zetian the principle of concave mirror focusing. Wu Zetian could not understand it, but Ming Chongyan on the other hand listened with relish, and he had gained insight.

Seeing this, Chen Yi moved his heart again, walked to Ming Chongyan, pointed to the gatehouse in front of the hall and said, "Doctor Ming, this gatehouse is very high. I wonder if Doctor Ming can measure this height?" Since he has shown his appearance today, let's continue showing off. Strike Ming Chongyan again.

"This..." Ming Chongyan looked at the gatehouses of several floors, and was a little confused about what Chen Yi pointed out. After thinking about it, he said: "You can go up to a high place and measure the height with a ruler. I guess there is a definite elevation when you rely on this building? Why did Chen Dajian ask this?"

Chen Yi smiled mysteriously, glanced at Wu Zetian who was curious and listened to him, and said confidently: "Doctor Ming is true, but he can use a very simple method to measure his height."

"I wish to hear it carefully." Ming Chongyan was both curious and surprised.

Wu Zetian and Wu Tuaner on the side also looked at Chen Yi with great interest, not knowing what wonderful way this little man who made them worried about came up with.

Chen Yi asked someone to find a pole, stand it in the courtyard, measure the height of the pole, and then measure the length of the shadow. After remembering these two heights, Chen Yi ordered the upper to measure the height of the gate building, and after a few simple calculations, he calculated the height of the gate building.

"Empress, at the same time and at the same position, the length of the projection of the object standing under the sun is proportional to its height. As long as you calculate this ratio, then measure the height of the object's shadow to be measured, and simply calculate it, you can calculate the height of the object we want to know." As he said that, he smiled at Ming Chongyan, very proud.

This is an extremely simple projection algorithm in arithmetic. In later generations, primary and junior high school students might be able to calculate, but people today may not know it. Just like the theory of the focus of convex lenses, although it is simple, it is not known until no one understands it.

After Chen Yi talked about the projection algorithm, he blew the Pythagorean law and trigonometric function to Wu Zetian. Wu Zetian was stunned when he heard it directly. Wu Tuan'er's eyes were starry, and Ming Chongyan looked like a black line. He sighed that today's show was not the time. Chen Yi knew the truth. Chen Yi knew half of the corners of the world, or he didn't know at all. It was really annoying. It seemed that Chen Yi's talent and knowledge were far from ordinary people. It was really not a false statement. Ming Chongyan felt deeply afraid of Chen Yi. Of course, there were some unspeakable reasons.

Ming Chongyan felt that Chen Yi's performance today was a bit targeted, just to suppress him in front of Wu Zetian, but he was powerless to do anything about it.

"Empress, Chen Dajian's talent is not comparable to me. I admire Chen Dajian very much. I hope to have the opportunity to learn from Chen Dajian's good students in the future." If I can't compare to others, I'll give in. Ming Chongyan will not be petty in such matters. He knew that if he showed righteous indignation towards Chen Yi at this time, he would definitely be disgusted by Wu Zetian. He took the initiative to admit defeat and showed a very demeanor, which would probably make Wu Zetian admire him, and it might not necessarily appreciate his demeanor. Anyway, he would have to show greatness no matter what.

Ming Chongyan's generousness really surprised Wu Zetian. He looked at him with admiration, but did not say anything to him. He just turned his face and said to Chen Yi: "Zi Ying, I really didn't expect that you would have so many masters of miscellaneous studies. I really underestimated you in the past. It seems that what you learned far out of my own accident, you will have to show more in front of me in the future, so that I can enjoy it with great pleasure."

"I will definitely not disappoint the Empress." Chen Yi agreed with courtesy. Ming Chongyan's performance still surprised him a little. This man who seemed to be only a little older than him had encountered setbacks and lost face in front of Wu Zetian. How could he have such a demeanor and look calm and look unstoppable and underestimated him. He could not lose to him in this regard. Chen Yi stood up and bowed to Ming Chongyan, and smiled and said, "Doctor Ming, what he chose just now is just some of his own expertise. There must be many things that doctor Ming has learned that have never heard of or seen before. If you have the opportunity to ask you more questions in the future."

Chen Yi was not so proud of his performance that he suppressed Ming Chongyan, which was a bit beyond Wu Zetian's surprise. When did this guy act so humble? Looking at the scene just now, he obviously wanted to humiliate Ming Chongyan in front of her. He gained a clear advantage in the skills competition and received her praise in person. He actually showed so gracefulness that he did not take advantage of the opportunity to humiliate Ming Chongyan. It was not simple.

Wu Zetian guessed Chen Yi's intention to do this, and was a little nervous and proud. This guy cared about her very much. He was "jealous" in such a thing and took the risk of angering her. When the palace competed with Ming Chongyan, he really knew how to do this, which made him even more anxious for a while when he thought of this, Wu Zetian showed a playful smile on his lips.

Although Ming Chongyan maintained a good demeanor, he was disappointed in front of Chen Yi today and felt very uncomfortable. He also knew that Chen Yi and Wu Zetian had something to talk about next, so he took the opportunity to say goodbye and leave first without disturbing them about the affairs of the court. Wu Tuaner was also very tactful, knowing that there were some private words between Chen Yi and Wu Zetian, and commanded other palace servants to retreat, leaving only Chen Yi and Wu Zetian in Qingliang Palace.

"Zi Ying, why did you suddenly come to me today? Is there anything important?" There was no one else beside me, and Wu Zetian spoke casually. After saying this casually, she lay down on the water bed. This cool water bed was also made according to Chen Yi's design, which allowed Wu Zetian to avoid the torture of sniffing the heat in midsummer, which made Wu Zetian quite satisfied.

This little man has a good head and always makes some useful things inadvertently, such as the water bed, chairs, shock-absorbing carriages, crystal sunglasses and other things, which made her amazed at his talent. His performance today made Wu Zetian even more surprised and curious about Chen Yi's talent. I really can't figure out where this little man learned these things from.

But today is not the time to ask these things. This little man may have resentment in his heart. He can't let him have resentment. He must accept everything she does. Let's hit him hard today

After asking, Wu Zetian looked at Chen Yi with a smile on his face, hoping that he could explain the reason for coming here to find her today.

"Empress, I heard that Doctor Ming was using some tricks to deceive you, and I was afraid that you would be deceived by him, so I rushed over."

Chen Yi did not hide the reason for coming here today, and continued in Wu Zetian's surprised eyes: "Empress, Doctor Ming is just a few tricks of confusing people. He uses agile techniques to make things difficult for him. There is nothing magical about him performing these jugglings in the palace. The purpose is just to arouse your interest and to follow the Empress to borrow the upper rank. Empress, you can't follow his will and let his plan succeed. Well, the secret he knows can be seen, it's really just a trick. Hehe, in terms of proficiency in miscellaneous studies, I am much better than him. If Empress is interested in these, I can often perform for you."
