Chapter 227

"Mr. Bai, what's the matter? How can the shadow of the guy in class 6 suddenly disappear?" all the participants in class 5 looked at the sudden changes in the field with a look of amazement. Even long Xin was surprised. Lin Feng couldn't help it, so he turned to look at Bai Xiaohei and asked, since Bai Xiaohei had seen that Bai Aoxue would win, So obviously, Bai Xiaohei knows the secret.

"Do you know how shadow is formed?" Bai Xiaohei did not directly answer Lin Feng's question, but asked.

"The shadow is a dark area where light is blocked by objects. Unless there is no light, there will be a shadow. But it's sunny now! How did Bai Aoxue get rid of the shadow?" Long Qing answered Bai Xiaohei's question and then asked.

"I'll explain it to you with my mouth. I guess you can't understand it. Purple charm condenses five or six ice mirrors." Bai Xiaohei smiled and asked Xiao Zimei.

Xiao Zimei nodded after hearing Bai Xiaohei's request. Then the ice blue light on her body began to flicker. Then six ice mirrors with a diameter of about 30 cm appeared on her hands.

At this time, the competition on the challenge arena has just ended, so the movement on Bai Xiaohei's side has attracted the attention of many viewers. Many people stare at Bai Xiaohei with curious eyes. They don't understand why these people waiting to fight under the stage should launch their courage?

Of course, Bai Xiaohei won't care about other people's eyes. He distributed six ice mirrors to six people, and then said to Liu Qingxia, "Qingxia, you stand here and don't move. Others stand around Qingxia and take pictures of her with the ice mirror in their hands. Remember to disperse some."

Hearing Bai Xiaohei's orders, the people acted according to their words. Six people holding ice mirrors stood in Liu Qingxia's six directions, raised their mirrors and began to look for the reflection point of light and shine on Liu Qingxia.

The first light shines on Liu Qingxia, leaving a long shadow under her feet. When the second light shines, the shadow fades and becomes two. In this way, six lights shine on Liu Qingxia successively, and a strange scene appears, and Liu Qingxia's shadow mysteriously disappears.

"... Miss Bai! We understand the way to make the shadow disappear, but what's the principle?" it's rare that long Xin asked Bai Xiaohei.

"It's actually very simple! You see, when a beam of light shines on an object from a given angle, the light will appear on the ground because it is blocked. After the second light shines, the shadow will be dispersed and begin to fade. This is the light refraction and halo effect. Diagonal light will weaken and disperse the shadow, and this is only two beams of light When the light angle reaches a certain number, the complex and staggered light will erase all the dead corners that form the shadow, so you can't see the shadow. "Bai Xiaohei drew a simple picture on the ground with a stone to explain to the public that in fact, the shadowless lamp specially used for surgery in Bai Xiaohei's world traditional Chinese medicine hospital is this principle, At that time, this was a well-known scientific common sense, that is, the world without science would make people feel so novel.

When Bai Xiaohei finished his explanation, someone in the audience nearest to them began to applaud, and even shouted, "you are worthy of being a teacher of the Dragon Theological Seminary, so young but so knowledgeable."

Bai Xiaohei didn't expect that his explanation would make the audience react like this. For a moment, Bai Aoxue was embarrassed to scratch her head. On the challenge arena, Bai Aoxue's eyes looked at Bai Xiaohei and became a little strange, even something more.

On the other side, mu Youqian twisted his beard and stared at class 5 with a smile. Lao De, the teaching director, looked at Bai Xiaohei with surprise: "headmaster, Bai Xiaohei has some skills! I thought he could only fool around!"

"I told you that this boy is not simple. Don't judge a person because of his age. Moreover, the boy's apparent age may not be true!" Mu Youqian said with an unfathomable face and a strange smile.

Lao De's face was full of doubts when he heard mu Youqian's words, but he didn't ask anything again, because the third competition in the challenge arena had begun.

This time in class 6, a girl with fire red hair came on the stage. The girl is very beautiful, but she is extremely masculine. The fire red hair is inch long short hair, and she is also wearing a boy's school uniform. If it weren't for the bulge of her chest position, I would think of her as a handsome boy at first glance.

After the short haired girl came on stage, she reported her name. Her name is yanene. She is a monk with fire attribute. Her courage level is level 16. From her careless way of speaking, we can see that the girl is a standard man and woman.

After the referee teacher announced the start of the competition, yan'en burned a raging flame and rushed directly towards Bai Aoxue. Bai Aoxue didn't contact yan'en at all. She moved in the field as if she were dancing. Of course, she was not idle. While avoiding the attack of yan'en, Bai Aoxue kept condensing the ability of ice attribute, It took two or three minutes to condense a huge ice hockey with a diameter of five meters over the challenge arena.

When the ice hockey is condensed, Bai Aoxue directly controls the ice hockey to hit yanene. As a monk with fire attribute, yanene can't be afraid even if it is not as high as Bai Aoxue, so he urges all his flames to send out a pillar of fire against the huge ice hockey.

When the fire column contacts with the ice hockey, the ice hockey melts rapidly, while Bai Aoxue outputs the ice attribute and maintains the shape of the ice hockey. A few seconds later, the ice hockey is full of melted water except the outer layer of ice.

All of a sudden, Bai Aoxue removes his support for the ice hockey. At the next moment, the ice hockey is melted by the fire, and a large amount of water falls from yanene's head, pouring yanene with a penetrating cold. While yanene is soaked, Bai Aoxue has strangely come behind yanene, and reaches out his hand to gently pat yanene on the shoulder. The next second, yanene's body trembles, Then the water on the body surface was frozen instantly. In this way, yanene was directly frozen into an ice sculpture.

Looking at Bai Aoxue on the challenge arena, Bai Xiaohei frowned, and then whispered to herself, "this girl named Bai Aoxue doesn't have to be so troublesome. She obviously wants to show her uniqueness by making such a big noise. Does she want to attract the attention of anyone?"

When Bai Xiaohei was talking to himself, he suddenly saw Bai Aoxue turn his head and look at himself, and the eyes were very strange. Bai Xiaohei even saw Bai Aoxue's lips move slightly. Judging from the lip shape, Bai Aoxue was saying to him, "it seems that we are the same!"
