"If so...... Is the biggest obstacle actually your own people? Xuan Ziwen was a little disappointed, and then he suddenly said, "Wait, this is just your side of the story, you don't have any evidence at all, right?" ”

"Maybe." Dai Huadong shrugged his shoulders and said indifferently, "But I know that no one will voluntarily hand over power, and that kind of person is either a saint or a fool...... However, at present, it seems that there are still a lot of fools in the three empires. ”

“……”

"It's far away, teacher, you go on." Dai Huadong coughed lightly, "You just thought I didn't say anything just now." ”

"......" Looking at Dai Huadong's appearance, Xuan Ziwen smiled bitterly and said, "You little guy...... Forget it, let's move on. ”

Next, Xuan Ziwen told them the principle of the soul guide and some innovative ideas, Dai Huadong took notes seriously, his memory was not as good as Xu Yiyi on the side.

Time flies when people are focused on something, and it feels like an hour has passed in the blink of an eye.

"Click-" The door of the laboratory opened, and Dai Huadong saw a black-haired girl walk in, about seventeen or eighteen years old, of course, the judgment may be a little inaccurate, Huo Yuhao's guy is obviously only fourteen years old, but he has a height of one meter eight like taking hormones, which causes Dai Huadong to be unable to see the other party's age from the appearance at all.

"Teacher, it's rare for you to be so early." The girl looked lazy, as if she didn't see Dai Huadong and Xu Yiyi at all, and then lay down in front of the experimental table, as if she had to make up for sleep.

"Ahem," Xuan Ziwen came back to his senses and said, "Tangerine, don't sleep, don't you see a newcomer here?" ”

The girl was still lying there, raised her right hand and waved it like a fly: "Don't make noise, let me sleep a little longer, you know I got late last night." The girl's voice was soft, giving people a feeling of itching.

Xuan Ziwen said helplessly: "Forget it, no matter what she is, she is like this, her name is Tangerine, and she is also a student I bring, you can call her senior sister in the future, she studied a soul guide last night until late, and an experiment was done in the middle of the night, so she only got up at this time." I took a total of four trainees with me, and the other three have gone out to practice, and it is estimated that it will be a few days before they come back. It's not too early, so let's stop here today, now tell me what the principle of that thing is? ”

"...... is it true that the brain circuits engaged in research are a little special? Just now, it looked like the three views were collapsing, and now it's full of vitality again?

"Okay, Xu Yiyi, you go back first, I'll explain it to Teacher Xuan. This thing is called a battery, which uses different active metals to react with acidic liquids to generate an electric current in the circuit, and uses the current to make the bulb shine...... "Dai Huadong began to explain the principle of the battery and the small bulb to Xuan Ziwen.

At first, Xuan Ziwen could understand it, but when it came to the electrons, positive charges, negative charges or something in the back, he was completely confused. He heard every word clearly, but when they put it together, he didn't recognize it at all.

Until noon, Dai Huadong leaned against the wall weakly and said, "I finally understand the mood of our math teacher at the beginning." Teacher Xuan, I have told you so many extra things, and I have to charge more. Since Xuan Ziwen really couldn't understand, Dai Huadong could only start from scratch to give him the material is made up of protons, neutrons, electrons, and milk...... Ahem, began to talk, which barely made Xuan Ziwen understand part of it.

"I still can't imagine how matter could be made of such spherical particles. And there is such a big gap. Xuan Ziwen looked at the white paper with the atomic model on the experimental table.

"It's just a simple diagram for you to understand a little bit, but in fact the gap is much bigger than that." Dai Huadong said, "Okay, teacher, don't forget the agreement with me. ”

"It's unimaginable......"

"Hmm...... What time is it? "The girl named Tangerine who was sleeping on the table before finally woke up at this time.

"Today is the year 20394 of the ephemeris, and you have been asleep for 30,000 years." Dai Huadong said seriously.

"Have I slept for so long......" The girl was still a little confused, and then suddenly reacted, "Huh?! What's the situation? I just slept for a while, how come 30,000 years have passed? ”

Then the girl looked around, this time she was finally completely awake, she looked at Dai Huadong angrily, and said, "Who are you?" How dare you lie to me! ”

Dai Huadong looked around and said to Xuan Ziwen: "Teacher Xuan, how can you deliberately deceive Senior Sister Tangerine?" ”

"Huh?" Xuan Ziwen was still immersed in his own world just now, and he didn't react for a while.

"Don't try to blame anyone! I know it's you! Tangerine pointed at Dai Huadong and said angrily.

"Cut!" Dai Huadong cut off, "It was actually discovered." ”

"Sure enough, it's you!" The orange directly threw an orange over and smashed it at Dai Huadong.

Dai Huadong seemed to be stupid, he didn't dodge or dodge, and then he was hit in the head by an orange......

Dai Huadong was stunned and touched the place where it was smashed, and then looked at the hand that had touched his head, the blood-red liquid was stained all over his hand, and at the same time, the blood-red liquid flowed down from his head.

The orange was dumbfounded, what she threw was just a very ordinary orange, at most it hurt a little when she hit it, so as not to smash people's heads and break the bloodstream.

Dai Huadong looked at the orange with resentful eyes, stretched out his hand stained with red liquid tremblingly, pointed at her and said, "You...... You're ......."

Before he finished speaking, his whole body suddenly fell backwards, and the red liquid flowed all over the ground.

Xuan Ziwen finally came back to his senses, he looked at Dai Huadong who fell to the ground with surprised eyes, and then looked at the helpless orange, and hurriedly came to Dai Huadong's side.

"Dai Huadong, how are you?" Xuan Ziwen helped Dai Huadong up and tried to press his wound with his hand, but this press found that there was a problem, there was no wound at all. Xuan Ziwen was stunned by his discovery.

At this time, Dai Huadong's weak voice sounded: "I...... I ask for compensation, medical expenses, and mental damages, and for the sake of you being a woman, I will charge you 100 billion in compensation. ”

Xuan Ziwen let go directly: "You guy is not injured at all!" ”

"Ouch!" Dai Huadong was hit by this blow, and let out a cry of pain, listening to the voice, there was no appearance of a dying person at all.

"You guy......" The orange who reacted suddenly burst into anger......
